How to judge the quality of XPS extrusion board

Extruded board is a new type of insulation material in the building insulation industry, which is widely used in the construction industry. However, the quality and price of extruded boards in the market are very different. Many people do not know how to distinguish high-quality and low-quality extruded boards Extruded board manufacturer Let's introduce.

one High quality extruded board has good thermal insulation performance. Extruded board is made of resin, Freon, hexabromo flame retardant and other components through foaming extrusion in the machine. This kind of board is made of continuous and uniform bubbles. The closed cell structure like honeycomb does not have voids at all, which can isolate air transmission and achieve thermal insulation effect. The thermal conductivity is only 0.028w/m.k, which can isolate the transmission of water vapor and achieve the effect of waterproof and moisture-proof, but the thermal insulation performance of low-quality extruded board is very poor. It will not be long before the structure of the whole product is changing.

2. High quality extruded board has very good compressive capacity. Due to its vacuum closed cell structure, the extruded board has high compressive strength and relatively high impact resistance. According to different models, thicknesses, unit weights and other specifications of the extruded board, its compressive strength is more than 220-500kpa and can withstand various ground loads. It can play a very good bearing role in some building construction, It can bear different loads, and can well block the impact on the outside world. It is widely used in geothermal floor heating boards, highways, airport runways, square floors, and large refrigerators.

However, the compressive capacity of the inferior extruded board is very poor. When it is used in pavement construction, the road deformation will occur after a short walk, which will have a great impact on the whole project.

three Grade B1 Plastic extruded board The anti-corrosion performance is very good, and the long-term use will not be affected by the external environment. The stability is particularly good, and the performance will not be reduced due to corrosion. The stability of low-quality extruded boards is particularly poor, and they may absorb water or be corroded after a short time.

Extruded boards are widely used in dry wall insulation, flat concrete roof and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, expressway and other fields of moisture-proof insulation.
