聚乙烯、聚乙烯和聚乙烯涂层是在彩钢表面喷涂的一层塑料，主要用于防潮和防腐。聚乙烯（PE）是由乙烯合成的高分子有机化合物。它可以分为两类：低分子量和高分子量。聚酯彩涂板制造商聚酯彩涂板价格天体彩涂板请致电上述网站咨询低分子量一般为液体、无色、无味、不溶于水、密度为0.92 g/cm 3，可用作润滑剂和油漆。高分子量一般为固体、乳白色、热塑性和手性。感觉像蜡，密度在0.92到0.96 g/cm 3之间。耐腐蚀，绝缘性好。高密度聚乙烯（HDPE）具有硬度高、硬度高、机械强度高等特点。可作为雷达、电视的容器、管道和高频绝缘材料。不溶于水，吸水性小。当温度高于70℃时，只能稍微溶解一些化学溶剂，如甲苯、乙酸等，但随着温度在15-40℃之间的变化，微粒聚腈可以熔化或固化，当温度升高时，可以吸收热量；当温度升高时，可以吸收热量。它能吸收热量。它收缩、凝固并散发热量。由于其吸水性小，不易受潮，保温性能好，是一种很好的建筑材料。颗粒状聚芝麻可与水泥混合制成墙壁和地板。根据室温下吸热熔化和放热凝固的特点，室温上升时熔化和吸热，温度下降时凝固和放热。这样可以保持室温稳定。因此，它是一种良好的蓄热材料。根据建筑材料的其他特点，它还具有防漏、防热防潮、防腐等功能。
Polyethylene, polyethylene and polyethylene coating are a layer of plastic sprayed on the surface of color steel, which are mainly used for moisture-proof and anti-corrosion. Polyethylene (PE) is a high molecular organic compound synthesized from ethylene. It can be divided into two categories: low molecular weight and high molecular weight. Polyester color coating board manufacturer polyester color coating board price TIANTI color coating board, please call the above website for consultation. The low molecular weight is generally liquid, colorless, tasteless, insoluble in water, and the density is 0.92 g / cm 3. It can be used as lubricant and paint. High molecular weight is generally solid, milky white, thermoplastic and chiral. It feels like wax with a density of 0.92 to 0.96 g / cm3. Corrosion resistance and good insulation. High density polyethylene (HDPE) has the characteristics of high hardness, high hardness and high mechanical strength. It can be used as containers, pipes and high-frequency insulating materials for radar and TV. Insoluble in water, low water absorption. When the temperature is higher than 70 ℃, only some chemical solvents, such as toluene and acetic acid, can be slightly dissolved. However, with the change of temperature between 15-40 ℃, the particulate polyacrylonitrile can melt or solidify. When the temperature increases, it can absorb heat; When the temperature rises, it can absorb heat. It absorbs heat. It shrinks, solidifies and emits heat. Because of its small water absorption, not easy to be affected by moisture and good thermal insulation performance, it is a good building material. Granular sesame seeds can be mixed with cement to make walls and floors. According to the characteristics of endothermic melting and exothermic solidification at room temperature, melting and endothermic when room temperature rises, solidification and exothermic when temperature decreases. This keeps the room temperature stable. Therefore, it is a good heat storage material. According to other characteristics of building materials, it also has the functions of leak proof, heat and moisture-proof, anti-corrosion and so on.
PE coating has good adhesion to materials, color coated steel plate is easy to process and form, low price and many products, and there is a large choice of color and luster. Polyester coating is not ideal for UV light resistance and film pulverization resistance, so the use of PE coating still needs to be limited. It is generally used in areas with less air pollution or products requiring multiple molding and processing. Because polyester contains active group - OH / - COOH, it is easy to react with other macromolecules and polymers. In order to improve the sunlight resistance and pulverization of PE, silicone resin with excellent color retention and heat resistance is used for denaturation reaction, and the denaturation ratio with PE can be between 5% - 50%. SMP provides better durability of steel plate, and its anti-corrosion life can be up to 10-12 years. Of course, its price is also higher than PE, However, because the adhesion and processing formability of silicone resin to materials are not ideal, SMP color coated steel plate is not suitable for occasions requiring multiple molding processing, and most of it is used for building roofs and exterior walls.
Everything is worth every penny. When we compare the quality of color coated steel plate, the price is on the one hand, but don't pay too much attention to the price of color coated steel plate. If the price of one color steel plate is much lower than that of others, we should pay attention to it. Therefore, it is also very important to choose color steel plate manufacturers.
