With the advancement of science and technology, more and more types of modern building materials are being built, and the performance is even more superior. Polyethylene plastic sheets are products based on the characteristics of polyethylene. Let's take a look at what polyethylene plastic sheets are.
What is polyethylene plastic plate
Polyethylene plastic is a synthetic resin, it is a kind of plastic, it is soft, feels good to touch, and it is transparent, good quality, etc. It has been applied in many aspects such as plastic bags, cling film and so on. Plastic plate is also the direction of application of this material. Polyethylene plastic plate can bring positive use and play a wide range of roles. If you need to purchase a large number of polyethylene plastic plates, you need to find a manufacturer of polyethylene plastic plates to customize.
Polyethylene chemical properties
Polyethylene has excellent chemical stability. It is resistant to hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide and other chemical substances at room temperature. Nitric acid and sulfuric acid have a strong destructive effect on polyethylene. Polyethylene is prone to photo-oxidation, thermal oxidation, and ozone decomposition, and is easily degraded under ultraviolet light. Carbon black has excellent light shielding effect on polyethylene. Crosslinking, chain scission, formation of unsaturated groups, etc. may occur after irradiation. reflect.
The performance of polyethylene depends on the way it is polymerized. At medium pressure (15-30 atmospheres), the Ziegler-Natta polymerized under the conditions of organic compounds is made of high-density polyethylene (HDPE). Polymerization under this condition Ethylene molecules are linear, and the molecular chain is very long, with molecular weights of up to several hundred thousand. If it is under high pressure (100-300 MPa), high temperature (190-210°C), peroxide polymerization catalyzes free radical polymerization to produce The low density polyethylene (LDPE), which is a branched structure.
Polymerization pressure: high pressure, medium pressure, low pressure;
The nature of polyethylene varies from species to species, depending on the molecular structure and density.
Polymerization method: slurry method, solution method, gas phase method;
Product density: high density, medium density, low density, linear low density;
Product molecular weight: low molecular weight, normal molecular weight, ultra high molecular weight.
What are the characteristics of polyethylene plastic plate
(1) Product features: High density, high hardness, high tensile strength, no water absorption (instead of traditional three-oil four-felt, asphalt-asphalt board and other materials). Product environmental protection, simple construction, seepage prevention, leakage prevention, cost cost Low, good water stop effect. Corrosion resistance, anti-aging, high temperature resistance +80°C~ -45°C no flow, no deformation, no brittle, long service life. The surface has an independent fine cell structure, with two-component poly The use of sulfur sealant and cement adhesive can be firmly integrated into one, naturally adapt to changes in expansion and contraction changes, enhance the expansion of the water stop effect.
(2) Application range of products: It can be widely applied to various concrete water stop joint projects such as river embankments, port terminals, underground culverts, hydropower stations, airport bridges, and room toilets.
(III) How to use the product: During construction, this product can be used in a variety of ways depending on the situation. Longitudinal sealing joints, horizontal sealing joints, horizontal sealing joints and other special joints.
