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 coatings are a layer of plastic sprayed on the surface of color steel, mainly damp-proof and anti-corrosion.
Polyethylene (PE) is a polymer organic compound synthesized from ethylene. It can be divided into two categories: low molecular weight and high molecular weight. Polyester color coated panel manufacturers polyester color coated panel price celestial object color panel please call the website above to consult low molecular weight generally liquid, colorless, tasteless, insoluble in water, density of 0.92 g/cm 3, can be used as lubricant and paint. High molecular weight is generally solid, Milky white, thermoplasticity and chirality. It feels like wax and has a density ranging from 0.92 to 0.96 g/cm 3. Corrosion resistance, good insulation. High density polyethylene (HDPE) has the characteristics of rigidity, high hardness and high mechanical strength. It can be used as containers, pipes and high frequency insulation materials for radar and TV. It is insoluble in water and has little water absorption. When the temperature is higher than 70 * C, it can only slightly dissolve some chemical solvents, such as toluene, acetic acid, etc. But with the change of temperature between 15 40 C, particulate polyZene can melt or solidify, when the temperature rises, it can absorb heat; when the temperature rises, it can absorb heat. It shrinks, solidifies and emits heat. Because of its small water absorption, not easy to damp, good thermal insulation performance, it is also a good building material. Granular polyZene can be mixed with cement to make walls and floors. Based on the characteristics of endothermic melting and exothermic solidification at room temperature, it melts and endotherms when room temperature rises and solidifies and exotherms when temperature decreases. This will keep the room temperature stable. Therefore, it is a good heat storage material. According to its other characteristics, the building material also has the functions of leak proof, heat proof and moisture proof, anti-corrosion and so on.
