Extruded sheet application features - extruded polystyrene sheet prices

What is XPS? 
Insulation boards are made of several materials, such as: asbestos, polyurethane foam board, XPS board, and others. XPS board extrusion means a direct way to produce out of the hard polystyrene foam board. XPS, and some other role in the housing plates and other construction and engineering fields is the thermal insulation. In addition, XPS can also be applied in the packaging of goods above. As building energy-saving insulation materials, XPS extruded plate can significantly reduce fuel consumption (ie, oil, gas, etc.) used for heating or electricity. Production process to make these plates owned by small and compact closed molecular structure, this knot closed GB basalt extruded plate xps configuration can make the heat conduction gas is maintained at a very limited space, so as to achieve the insulation effect . This feature also brings to the plate impermeable performance. You can buy XPS in the building materials market. XPS board is also available from the manufacturer that extruded board insulation tiles later years. Different manufacturers, sheet having a color which there are differences, such as: pink, blue or green. 

XPS board application characteristics:
First, high compressive strength, hot extruded board has 150KPa - 600KPa variety of models to meet various load requirements. Such as: the square ground, roof parking, rooftop tennis court, roof garden, as well as by long-term load platform ground, highway and railway roadbed, etc.
Second, the superior insulation properties as a thermal insulation material, extruded sheet guide coefficient is less than 0.03w / mk, 70% relative humidity extruded plate in this regard under the obvious degree, extruded sheet in this regard clearly superior to other insulation material and insulation performance over time is very small, after decades of using insulation performance still more than 80%
Third, good noise performance noise reduction, noise insulation extruded plate unique performance, so you both at the hotel or in the KTV rooms, also, or at home, do not interference and influence others to worry about the outside world, so that this feature is particularly in the home decoration, construction decoration in advantage. 

Fourth, excellent moisture barrier performance, extruded sheet having closely obturator cellular structure of polystyrene molecule itself does not absorb water so that it has excellent resistance to water vapor permeability Handan extruded board , water absorption than normal hair polystyrene foam board about 10 times smaller, only absorb a small amount of water at the initial stage, after it is no longer water; its water vapor permeability than the foamed polystyrene 2-4 times. Therefore, in addition to extruded board can effectively prevent the intrusion of rain and moisture penetration, but also effectively prevent the internal material due to condensation of water, due to thawing and bursting.
Fifth, good environmental performance, stable chemical properties of extruded plate, less volatile decomposition, mildew; has good corrosion resistance of its high-performance thermal insulation function, can reduce the consumption of natural resources; it produces recyclable solid waste process used in full compliance with the requirements of the world's sustainable development strategy is a new type of environmentally friendly products.

XPS recycling is an important industry which should be developed rapidly.

Developed countries waste plastics strategies

Currently, the majority of waste plastics are thermoplastics, due to the molecular structure is not too much damage, after sorting, washing, drying, grinding, mixing the ingredients, granulating, such a process can be re-processed into plastic products. Waste plastics and renewable energy than new material resin savings of 85% to 90%, saving energy processing 6% to 17%.
After the waste plastics processed into granules, the material still has good overall performance, meet blown film, drawing, tube drawing, injection molding, extrusion profiles and other technical requirements, widely used in plastic products.
Japan, as one of the countries producing plastic, plastic scrap its huge annual emissions, accounting for 30% to 50% of household waste by volume. Coupled with Japan’s land area is small, densely populated and has a lot of plastic waste cannot be incinerated or buried use manner. On the other hand, Japan’s lack of resources, companies need plastic waste as a resource to be recycled, the establishment of a recycling-oriented society.

At present, Japan will not be able to collect a single species, it is difficult according to the type of plastic waste sorting as heat recovery, substituted for blast furnace coke as a reducing agent, is used as a fuel in cement kilns. Fuel used for a variety of re-generating boilers, part of the oil fuel can be used in cars , including solid fuel technology, fuel-based powder, an aqueous slurry of solid fuel technology, thermal decomposition of oil and so on.
Plastic waste oil can get higher-value liquid fuel or chemical raw materials, and other heat recovery and fuel-based method can only be referred to alternative coal or gas, it is the oil recovery method stipulated by the Government of Japan mixed waste plastics. It is internationally recognized as the ideal method.

Italy is the recycling of waste plastics in Europe doing the best work of the State. Italian waste plastics accounted for about 4% of municipal solid waste, the recovery rate of up to 28%. In addition, Italy has also developed a separate waste plastics from municipal solid waste in machinery and equipment.

The United States had carried out the recovery and utilization of waste plastics in the early 1960s, on the use of thermal energy is extracted from the thermal decomposition of waste plastics technology research chemical raw materials, has achieved some success. In addition to solving the problem of plastic waste, states also adopt legislative and other compulsory measures. Plastic recycling are popular in many developed countries, as a developing country, China should accelerate the pace of recycling industry.

Waste plastic recycling system "Situation and Countermeasures"

  Due to the extensive use of plastics and good performance, plastic and steel, timber, cement form the four basic materials of modern industry, and promote the sustainable development of agriculture and industry and the rise of modern high-tech. The total amount of waste plastics was born is also rapid growth, the intensification of the contradiction between environment and development.
   Ecological crisis caused by plastic waste
   It is well known as a novel plastic material, because of its excellent performance, easy processing, low prices and rapid development, increasing penetration into daily life. However, with plastic products are widely used, with the large number of applications of plastics, waste generated is also increasing, causing serious pollution of the human environment. In particular plastic packaging material.

    According to incomplete statistics, in developed countries, the proportion of plastic waste in Europe and throughout the city waste in order to calculate the weight of close to 10% in terms of volume as high as 30% to 40%.
    And a lot of plastic waste scattered, even buried, also need 200 years to resolve, not to mention the plastic will be buried in soil and pollute underground water, destroy the soil structure.
    Therefore, recycling of waste plastics, as a cost-saving energy measures to protect the environment, has been a high degree of foreign enterprises and government. A recycling machine is important to an enterprise.

The reason behind the difficult Styrofoam waste recycling

Styrofoam is used in all aspects of our lives, such as food packaging, foam cups, Styrofoam boxes and so on. Recycled Styrofoam granules have a huge market potential and value. However, waste Styrofoam recycling is not an easy thing.

The first is the policy.

Our country waste plastic recycling is mainly by « picking up bottles » and other private channels to complete the recycling of waste plastics. Recently, however, affected by oil prices, recycling of waste plastic bottles almost unprofitable, picking up the bottle the enthusiasm of the army was gone, recycled plastic bottles has been greatly affected. Thus, the government should establish an official recycling channels, so that when the interests of the market recovery cannot drive people to ensure the normal inflow of waste plastics recycling plant. From policy should support regular plastic recycling enterprises, improve the mechanisms and standard plastic recycling, waste plastic recycling there is a clear quantitative criteria.

Second, the technical aspects

The method of recycling of plastics mainly for the physical regeneration, will recycle plastic waste through sorting, washing, processing directly after granulation molding. Waste plastics renewable way there are many, in addition to physical recovery also includes energy recovery, chemical reduction, and used as a solid fuel. Processing and utilization of waste plastics technology level is relatively low, a lot of waste plastic processing enterprises do not have the strength of the introduction of foreign advanced technology, but also unable to develop new technologies and processes.

Governments should accelerate their pace to help enterprises develop plastic recycling, it is the same important as Styrofoam recycling.

The recycling of EPS packaging

In Australia, about 45,000 tons of expanded polystyrene (EPS) is created and consumed each year. 
Much of this EPS is embedded in long-term use (such as waffle pods used in housing construction and engineering/manufacturing components) however, approximately 40% (or 18,000 tonnes p.a) is single-use or short-term packaging that can be recycled after use. We currently only recycle about 27% (or 4,900 tonnes p.a.) of this EPS packaging，so there is a plenty of opportunity to recycle more. 

MWRRG is currently looking at ways to assist industry, businesses and councils in metropolitan Melbourne to recover more EPS packaging and divert it from landfill for reprocessing.

Look for ways that you can reduce the amount of polystyrene waste that you generate.

Polystyrene packaging can’t be recycled from your kerbside recycling bin, and when thrown in your garbage bin it ends up taking up precious space in landfill, and does not break down. So, taking actions to realize polystyrene recycling is important.

Using a reusable cup instead of the disposable polystyrene cups will stop some polystyrene from entering the waste stream.

Polystyrene meat trays are not accepted for recycling because they are contaminated by uncooked meat products; they must be disposed of in your general trash. Biodegradable meat trays made from plant oils are in development but are not widely available due to high manufacturing costs. Improvements in manufacturing efficiency will hopefully bring the cost of these trays closer to the cost of polystyrene food trays and we will begin to see more and more of them on our supermarket shelves.

Because of the varied uses for EPS, recycling requirements are a little more complex than, say, paper and other plastics, but it is worth taking the time in order to keep this prevalent material in use and out of landfills.

The Use of Expanded Polystyrene Will Be Limited

Expanded Polystyrene (EPS) is widely used in mechanical equipment, instrumentation, household electrical appliances, handicrafts and other fragile products vulnerable to shock packaging materials and fast food packaging. However, after use, the waste of polystyrene foam has light weight, large volume, and has anti-aging, it is difficulty to corrosion, which as a major waste disposal problems. According to the latest news, about the restricted use of expanded polystyrene, the Canadian Plastics Industry Association San Francisco's expanded polystyrene restrictions and it will be extended to items such as foamed egg trays.

It is reported that San Francisco's goal is to become a "zero waste" of the city in 2020, and other US cities are also take actions, including the ban in court last year in New York, and from January 1,2017, to take food EPS ban in Washington.

The board of supervisors voted unanimously to introduce a ban on foamed polystyrene since 2017, which includes peanut packaging, coffee mugs, cooling systems, toys and marine buoys. From July 1, 2017, even the supermarket meat, fish and eggs boxes will be removed.

Much of this EPS is embedded in long-term use (such as waffle pods used in housing construction and engineering/manufacturing components), however, approximately 40% (or 18,000 tonnes p.a) is single-use or short-term packaging that can be recycled after use. We currently only recycle about 27% (or 4,900 tonnes p.a.) of this EPS packaging so there is plenty of opportunity to recycle more. So, we should try our best to take actions in polystyrene recycling. people can collect the waste polystyrene products and throw them into the specific recycling bins. Many cities have machines that can process these waste into renewable useful products. 

Plastic waste pollution should be paid more attention

Recently, this is a report that a coral whale has been stranded in the west coast of Norway. The animal protection department was forced to euthanize this coral whale, and the researchers decided to give the coral beak whale which weigh up to 2020 kilograms a mercy killing, and plans to put its skeleton at the University of Bergen Museum. In the anatomy of this head Ziphius cavirostris, the researchers found that its belly stuffed with a large number of plastic products. Involved in anatomical work, University of Bergen zoologist Lys Levante said that the first Ziphius cavirostris's abdomen filled with plastic products, including at least 30 plastic bags and other small things, the digestive system has no food, and almost all blocked by plastic particles,which may result in severe pain due to plastic clogging. 

Though this thing, we can find that Marine plastic waste pollution is one of the serious environmental problems. Plastic waste pollution such as polystyrene can be consumed by fishes once it breaks down in the ocean. Marine animals higher up the food chain could eat the fishes that have consumed EPS, thus concentrating the contaminant. It could be a potential health hazard for us humans who are on top of the food chain considering that styrene, the plastic monomer used in manufacturing EPS has been classified by the US National Institutes of Health (NIH) and the International Agency for Research on Cancer (IARC) as a possible human carcinogen. Styrene is derived from either petroleum or natural gas, both of which are non-renewable and are rapidly being depleted, creating environmental sustainability problems for EPS. 

So, we should find solutions to solve this question, and plastic recycling such as polystyrene recycling is an important and a good way to reduce this kind of plastic pollution.

Extruded polystyrene foam board has been introduced

Extrusion foam insulation board is a kind of insulation material, mainly used for building insulation, cold storage, highways, railway subgrade and other fields. And xps raw material is polystyrene resin. In 2013, China's total output of extruded foam reached 19 million m³, the market share has more than 70% in the building insulation materials. It is reported that the world's most advanced environmentally friendly extruded polystyrene foam board project officially settled in Tianjin.

In 2011 through the Ministry of Environmental Protection and the United Nations Development Program and other relevant agencies to assess the official into the China Environmental Protection Association governing units, China Building Materials Association governing units. This indicates that the Tianjin world sunshine will face a greater opportunity for development, will also lead the entire Tianjin and North China-related insulation products to further upgrade, and then for China's environmental protection and energy conservation to make a more solid contribution.

China's extruded foam insulation board industry is currently the main use of hydrogen fluoride-containing blowing agent. This kind of blowing agent to disperse into the atmosphere will damage the ozone layer, but also has a strong greenhouse gas, produce benzene, formaldehyde and other harmful substances, do great harm to the human body. Therefore, the accelerated phase-out of hydrochlorofluorocarbons is not only significant for the protection of the ozone layer, but also greatly slows global warming.

After using it, it can also be recycled through take such action as Styrofoam recycling. And then we can use it to do other products.

Hidden dangers in Khan steam room

The survey found that some of the Khan steam room heating method using electric heating film of the ground and wall, insulation layer using extruded polystyrene foam board which use polystyrene as xps raw material and other flammable combustible materials, and electric film often use polymer combustible materials, which easily lead to casualties. On top of that, polystyrene can also be recycled, we can take such actions as EPS recycling.

Fire fighters said that if you want to eliminate sweat steam room fire accident, you must analyze sweat steam room interior decoration, electrical wiring layout and working principle and other fire safety weaknesses carefully. Khan steam room must be decorated by formal, qualified professional decoration company and decoration materials must be produced by regular manufacturers to meet national standards. Sweat steam room must be responsible for the safety of personnel management of safe work.

Khan steam room shall not be pasted, decorated, hanging any items, to avoid the impact of heat caused by a fire accident. Khan steam room can not act as "drying room" use, after heating the ground can not stack any clothing, towels, bedding and other items, so as not to be timely damage to heat plus heating system, causing a fire. Sweat steam room are all the electrical appliances, circuits, lights, temperature control systems, electrical and other related electrical equipment, are not allowed to change and move The location, in order to avoid accidents.

Sweat steam floor of the ground due to heating system, it can not be added, placed, covered with any seats, stools, furniture and other items, so as not to cause heat caused by fire; sweat steam room service staff must master independence, to deal with the relevant knowledge of accidents, and have contingency contingency handling capacity; Khan steam room shall not be free to increase the heating facilities; Khan steam room must be equipped with emergency fire measures, in a clear position placed foam fire extinguishers.

Types of waterproof plates

The main types of waterproof sheet include: PVC board, color steel plate, EVA waterproof board and XPS board.

1, PVC board

Pvc is the most common material in the market plastic, and pvc as raw material with cross-section of the honeycomb-like mesh structure of the plate, this board is light and the price is relatively low compared to wood, it can keep from moth, and with the characteristic of insulation and waterproof, is the most commomly used waterproof sheet, pvc plastic does not absorb water, so waterproof is its basic principles.

2, color steel plate

Color steel plate, also known as color coated steel plate, is in the steel plate with a layer of organic coating, so as to achieve the effect of waterproof and corrosion-resistant. The color plates we often see in our lives are the roof of the board, and they are exposed to the outside without rusting even in the rainy season. Color steel outside the layer of special coating is made of silicon modified polyester or polyvinylidene fluoride and plastic sol composition, durability is very strong, shelf life is generally 10 to 15 years, and as long as every 10 spray a paint, Then the average life expectancy can reach more than 35 years.

3, EVA waterproof board

EVA waterproof board is also one of the important waterproof sheet, in fact, EVA has been very common in life. It is very light, and wear, corrosion resistance, waterproof, with a buffer effect. EVA made with hot melt adhesive plate also has the same characteristics, light and water, the price is not high, but also with thermal insulation properties.

4, XPS extruded board

XPS extruded board is extruded polystyrene insulation board, is the third generation of rigid foam insulation material, it is polystyrene resin as xps raw material and aggregates, through a special process of heating mixed with a catalyst, and then extruded to produce a rigid foam sheet. This kind of board can be recycled through polystyrene recycling, and also can be recycled to do other products.
