聚乙烯、聚乙烯和聚乙烯涂層是在彩鋼表面噴涂的一層塑料，主要用于防潮和防腐。聚乙烯（PE）是由乙烯合成的高分子有機化合物。它可以分為兩類：低分子量和高分子量。聚酯彩涂板制造商聚酯彩涂板價格天體彩涂板請致電上述網(wǎng)站咨詢低分子量一般為液體、無色、無味、不溶于水、密度為0.92 g/cm 3，可用作潤滑劑和油漆。高分子量一般為固體、乳白色、熱塑性和手性。感覺像蠟，密度在0.92到0.96 g/cm 3之間。耐腐蝕，絕緣性好。高密度聚乙烯（HDPE）具有硬度高、硬度高、機械強度高等特點。可作為雷達、電視的容器、管道和高頻絕緣材料。不溶于水，吸水性小。當溫度高于70℃時，只能稍微溶解一些化學溶劑，如甲苯、乙酸等，但隨著溫度在15-40℃之間的變化，微粒聚腈可以熔化或固化，當溫度升高時，可以吸收熱量；當溫度升高時，可以吸收熱量。它能吸收熱量。它收縮、凝固并散發(fā)熱量。由于其吸水性小，不易受潮，保溫性能好，是一種很好的建筑材料。顆粒狀聚芝麻可與水泥混合制成墻壁和地板。根據(jù)室溫下吸熱熔化和放熱凝固的特點，室溫上升時熔化和吸熱，溫度下降時凝固和放熱。這樣可以保持室溫穩(wěn)定。因此，它是一種良好的蓄熱材料。根據(jù)建筑材料的其他特點，它還具有防漏、防熱防潮、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涂料對于材質(zhì)有良好的附著性，彩涂鋼板易于加工成型，價廉且產(chǎn)品多，顏色和光澤的選擇余地大。聚酯涂料對耐紫外光性與涂膜耐粉化性，并不理想，因此PE涂料的使用仍需受到一些限制，一般用在空氣污染不嚴重的地區(qū)或需多次成型加工的產(chǎn)品。由于聚酯含有活性基-OH/-COOH，極易和其它高分子化和物反應(yīng)，為改良PE的耐陽光性與粉化性，以色澤保持性與耐熱性優(yōu)的Silicone樹脂作變性反應(yīng)，和PE的變性比可于5%—50%之間，SMP提供鋼板更好的持久性，其防蝕年限可長達10-12年，當然其價格也比較PE為高，但因Silicone樹脂對材質(zhì)的附著性和加工成型性并不理想，因此SMP彩涂鋼板并不適用于需多次成型加工的場合，大部分用于建筑屋頂及外墻。
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.
任何東西，都是一分錢一分貨。我們在比較彩涂鋼板質(zhì)量的時候，價格是一方面，但是也不要太注重彩涂鋼板價格。如果一種彩鋼板的價格別其他的低很多，那么我們就要有所注意了。所以，選擇彩鋼板廠家也是很重要的。佛山市萬慶物資有限公司，位于華南鋼材集散地——樂從鋼材批發(fā)市場。我司自備庫存，可發(fā)往全國各地，物流暢通四方。
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.
