产品细节

用于PMMA塑料眼镜的纯丙烯酸PMMA树脂

主要介绍：

1. 聚甲基丙烯酸甲酯（PMMA）的导热系数和比热容量属于中等水平，为0.19w/cm。k和1464j/kg。K、 分别

   甲基的极性不是很大，PMMA仍然具有良好的介电和电绝缘性能。值得指出的是，聚甲基丙烯酸甲酯和整个丙烯酸塑料具有优异的耐电弧性能。在电弧的作用下，表面不会有碳化的导电路径和电弧轨迹

   耐化学性和耐溶剂性
   聚甲基丙烯酸甲酯可抵抗稀无机酸，但浓无机酸可使其耐腐蚀和耐碱，但温氢氧化钠和氢氧化钾可使其耐腐蚀、耐盐和油脂、耐脂肪烃、不溶于水、乙醇、甘油等，但可吸收酒精溶胀，并产生抗应力开裂、抗酮、抗氯代烃和抗芳烃

3. 耐候性
   聚甲基丙烯酸甲酯（PMMA）具有优异的耐大气老化性能。经过4年的自然老化试验，其重量发生变化，抗拉强度和透光率略有下降，颜色略有变黄，抗银纹性明显降低，冲击强度略有提高，其他物理性能基本不变。一种
   5。可燃性
   聚甲基丙烯酸甲酯易于燃烧，其极限氧指数仅为17.3

   主要优点：

   1. 通常被称为有机玻璃的聚甲基丙烯酸甲酯（PMMA）具有透明度高、价格低、易于加工等优点

   2. 它通常被用作玻璃替代材料

   4. 有机玻璃是一种重要的热塑性塑料，发展较早，具有透明、稳定、耐候、易染色、易加工、美观等特点，广泛应用于建筑行业

   Main Introduction:

   1. The thermal conductivity and specific heat capacity of polymethyl methacrylate (PMMA) belong to the middle level, which are 0.19w/cm.k and 1464j / kg. K, respectively.

   2. The polarity of the methyl group is not very large, and PMMA still has good dielectric and electrical insulation properties. It is worth pointing out that polymethyl methacrylate and the whole acrylic plastics have excellent arc resistance. Under the action of electric arc, there will be no carbonized conductive path and arc track on the surface.

      Chemical resistance and solvent resistance
      Polymethyl methacrylate can resist dilute inorganic acid, but concentrated inorganic acid can make it erode and alkali resistant, but warm sodium hydroxide and potassium hydroxide can make it erode, salt and grease resistant, fatty hydrocarbon resistant, insoluble in water, ethanol, glycerin, etc., but it can absorb alcohol swelling, and produce stress cracking, ketone, chlorinated hydrocarbon and aromatic hydrocarbon resistant.

   3. Weather resistance
      Polymethyl methacrylate (PMMA) has excellent atmospheric aging resistance. After 4 years of natural aging test, its weight changes, tensile strength and light transmittance slightly decrease, its color slightly turns yellow, its craze resistance decreases obviously, its impact strength slightly increases, and its other physical properties hardly change. A kind of
      5. Flammability
      Polymethyl methacrylate is easy to burn and its limited oxygen index is only 17.3.

   Main Advantage:

   1. Polymethyl methacrylate (PMMA), which is usually called organic glass, has the advantages of high transparency, low price, easy machining and so on.

   2. It is often used as a glass substitute material.

   3. A kind of Plexiglass is an important thermoplastic developed earlier, with transparency, stability and weather resistance, easy to dye, easy to process, beautiful appearance, widely used in the construction industry.
