What are the specific uses of EPS materials?

EPS is short for Expandable Polystyrene Sheet, which is made from raw materials that have been pre-haired, cooked, shaped, dried and cut. It can be made into different densities, different shapes of foam products, but also to produce a variety of different thicknesses of foam sheets. So what are the specific uses of EPS materials?
▲EPS raw materials
01 Packaging materials
EPS is a thermoplastic material, consisting of about 98% air and 2% polystyrene. As the density can be as low as 10-30kg/m3 , eps is currently the lightest packaging material, under high load, this material will be bent, when subjected to shock or falling to the ground, EPS products will play a cushioning, shock-proof role. Suitable for fragile products, mechanical parts, electrical appliances, electronics, automotive parts and other industries.
02 External wall insulation building materials
EPS buffer material can also be made into EPS insulation board, which is conducive to the maintenance of room temperature, the choice of external wall insulation, because the wall heat storage capacity of the larger layout layer in the inner side of the wall, which is conducive to the maintenance of room temperature stability. If the eps foam is used in the external insulation system of the external wall, its apparent density must comply with JG149-2003 "expanded polystyrene board thin plaster external wall external insulation system" standard requirements, that is, the apparent density in 18-22kg/m3.
At the same time, it can also play a role in the maintenance of the main layout of the building, extending the life of the building. Because the external insulation is placed on the outside of the layout, it reduces the stress caused by the deformation of the layout due to temperature change and reduces the corrosion of the layout by harmful substances in the air and ultraviolet light.
03 EPS wall materials
The cavity polystyrene module (EPS module for short) concrete wall has the following advantages, such as structural and thermal insulation integration and simple construction.
(1) eliminating backward production processes, standardisation, factory and scale production of modules.
(2) The unique plugging and jointing of the enterprise mouth, to ensure the accuracy of the module installation combination.
(3) The unique cavity construction combination connection method ensures the accurate size of the composite wall section.
(4) The creation of the module as an external demolition-free formwork for cast-in-place concrete shear walls, with integrated wall structure.
(5) Unique nodal structure, the bottom blocked the "cold bridge", to achieve the overall sealing of the external insulation layer of the house to ensure that the energy-saving building as a whole to meet the design standards.
(6) The unique dovetail design of the module surface allows for the paste of decorative tiles on the external wall surface.
(7) Improve the durability of the building, so that the insulation layer and the structural wall of the same life.
The cavity polystyrene module (referred to as EPS module) concrete wall can be applied to the fire resistance level three (B1) and below, seismic intensity 8 degrees and below, above-ground building height 15m and below, above-ground building number 3 floors and below, no support wall column when the building floor height is not more than 5.1m industrial and civil building external wall. Its design, construction and acceptance are in accordance with the "JGJ/T 420-2017 Technical Regulations for the Application of Polyphenylene Module Insulation Wall".
The product can be widely used in the construction of urban and rural villas, such as ecological livability, relocation, poverty alleviation, post-disaster reconstruction, beautiful countryside and characteristic towns.
04 Decorative lines
EPS decorative lines are a new type of exterior decorative lines and components, suitable for installation on the exterior EPS, XPS insulation walls, which can reflect the European classical, elegant decorative style, but also to ensure that the main building exterior wall does not appear cold, thermal bridge effect.
Especially for the European style of high-rise buildings, the installation of cement components is very difficult, long construction period, time will appear cracks, poor durability, and the use of EPS decorative lines, with the advantages of easy installation, economic, long durability, etc. EPS decorative lines are stripped B2 level fire polystyrene as the main body, paste alkali-resistant glass fibre mesh cloth, with a special bonding outside the protective layer composite. It is not affected by temperature changes, cold and heat resistance; not affected by humid climate and acid rain.
EPS decorative lines are fire resistant and do not emit toxic substances, and are environmentally friendly, high quality decorative building materials. EPS decorative lines are cut by computer numerical control and are quick to produce, with a wide variety of models, such as lines, Roman columns, window casings, arches, etc., which can be installed on the four sides of windows, door edges, cornices and walls; making the building facade more beautiful.
Our graphene EPS has better performance than traditional EPS, high strength ≧ 0.3Mpa, lower thermal conductivity ≦ 0.030w/m.k, to B1 fire performance, its series of products fully comply with the national vigorous development of low-energy building requirements, in the assembly of low-energy buildings have been applied and demonstration.
