塑料原料聚甲醛颗粒

聚甲醛塑料性能的优缺点：

1。优点：

聚甲醛具有良好的尺寸稳定性，价格低廉，表面硬度高，表面致密，耐常用化学品和溶剂，电性能好。良好的机械性能和刚性，接近金属材料，虽然收缩率大，但尺寸稳定。重量轻，是取代铜、铸锌、铝和其他金属材料的理想选择；优异的抗疲劳和蠕变性能。消除外力后，立即恢复原状，具有良好的耐磨性、自润滑性和摩擦性。Pom、UHMWPE、PA和F4统称为四种主要的耐磨塑料材料。它们具有很高的热稳定性和化学稳定性、良好的介电性能和良好的电气绝缘性。耐溶剂，无应力开裂

2。缺点：

聚甲醛容易受热分解，成型收缩率大，成型难度高于尼龙。密度高，耐酸性和阻燃性差，耐候性差。熔点不是很高。在较高温度下，热降解非常迅速。氧存在时也会发生热氧化降解

3。均聚和共聚比较：

均聚材料具有良好的延展性和耐疲劳性，但不易加工。该共聚物材料具有良好的热稳定性、化学稳定性和易加工性。除上述性能外，HPO还具有较高的密度、结晶度和机械强度。缩醛共聚物的短期强度、模量、伸长率、热变形温度、抗蠕变性、耐热老化性和耐热水性均优于均聚甲醛，成型温度范围更宽

4。加工方法：

注塑、挤压、吹塑、旋转成型、焊接、粘接、涂层、印刷、电镀、机加工、注塑是最重要的加工方法。注射压力：700-1200bar。注射速度：中等或高

Advantages and disadvantages of POM plastic performance:

1. Advantages:

POM has good dimensional stability, cheap price, high surface hardness and dense surface, can withstand common chemicals and solvents, and has good electrical properties. Good mechanical properties and rigidity, close to metal materials, although the shrinkage rate is large, but the size is stable. Lightweight and ideal for replacing copper, cast zinc, aluminum and other metal materials; excellent fatigue and creep resistance. After removing the external force, it returns to the original state immediately, with good wear resistance, self-lubrication and friction.Pom, UHMWPE, PA and F4 are collectively referred to as the four major wear-resistant plastic materials. They have high thermal and chemical stability, good dielectric properties, and excellent electrical insulation. Solvent resistant, no stress cracking.

2. Disadvantages:

POM is easy to be decomposed by heating, the molding shrinkage rate is large, and the molding difficulty is higher than that of nylon. High density, poor acid resistance and flame retardancy, and poor weather resistance. Melting point is not very high. At higher temperatures, thermal degradation is very rapid. Thermo-oxidative degradation also occurs in the presence of oxygen.

3. Homopolymerization and copolymerization comparison:

Homopolymer materials have good ductility and fatigue resistance, but are not easy to process. The copolymer material has good thermal stability, chemical stability and ease of processing. In addition to the above properties, HPO also has high density, crystallinity and mechanical strength. The short-term strength, modulus, elongation, heat distortion temperature, creep resistance, heat aging resistance, and hot water resistance of acetal copolymers are better than those of homoformaldehyde, and the molding temperature range is wider.

4. Processing method:

Injection molding, extrusion, blow molding, rotational molding, welding, bonding, coating, printing, electroplating, machining, injection molding are the most important processing methods. Injection pressure: 700-1200bar. Injection speed: medium or high.
