Construction technology and performance of high density polyethylene board

Construction technology and performance of high density polyethylene board

是一种结晶度高、无极性的热塑性树脂。 High density polyethylene board is a kind of high crystallinity, non-polar thermoplastic resin. It has the characteristics of high toughness, tensile resistance, corrosion resistance, low temperature resistance and good wear resistance. Widely used in chemical, clothing, packaging, food and other fields. It can be filled, flame retardant, modified, embossed and ground. LDPE (high-pressure low-density polyethylene) is soft, low in mechanical strength, and low in melting point. Suitable for film and cable insulation. HDPE (low pressure high density polyethylene) has higher rigidity, higher mechanical strength and higher melting point. Suitable for making hollow products.

With the maturity of our technology, polymer brackets will be more widely used in our lives. In making and decorating houses, various PE boards and other materials are often used. What problems should be noticed in the construction of sports boards? Let's see it together.

By improving the construction process, high-molecular brackets can obtain high-quality PE boards. The main improvement measures are Grasp the problem of feed volume, determine the required amount of material in advance to avoid too much or shortage of material, adjust the higher material amount of PE board, it is best to use high-pressure rapid injection method to produce PE board to get better board. The construction process of polymer support bars is simple, the raw materials are poor in fluidity, and some difficulties are encountered in production. Therefore, attention must be paid to the selection of raw materials. By improving the construction process, the polymer bracket can achieve better quality, so pay more attention to the above problems in the construction, and it can easily achieve the optimization of the quality of the PE board.

由聚乙烯树脂制成。 The high-density polyethylene board is made of polyethylene resin. For milky white, odorless, odorless, non-toxic plastic sheet with melting point of 124C, degradable plastics are mainly divided into photodegradation and thermal degradation, water degradation and biodegradation. Biodegradation is the main trend. In addition, if a carbonyl photosensitizer is to be added, a carbonyl photosensitizer is usually added to the photodegradable material, and the carbonyl photosensitizer absorbs infrared rays or a metal photosensitizer. The catalytic effect is: cobalt cobalt> molybdenum> copper> copper> iron iron> vanadium vanadium. Polyethylene resin is a polymer composed of many ethylene molecules. Due to its stable chemistry, pendant groups are eliminated upon heating. The main chain usually breaks or breaks weak bonds, which has little effect on its performance. Non-degradable plastic
