In the internal gallbladder and various plastic products of various types of refrigerators produced by our factory, the ABS injection products account for more than 88% of the total of the total of the refrigerator plastic products, which belong to the amorphous polymer and he no obvious melting point.【通用隨機圖片】
EVA 1、含量在5%以下的EVA,其主要產品是薄膜、電線電纜、LDPE改性劑、膠粘劑等;2、含量在5%~10%的EVA產品為彈性薄膜等;3、含量在20~28%的EVA,主要用于熱熔粘合劑和涂層制品;EVA是由LLDPE(線性低密度聚)和醋酸(VA)共聚而成。
EVA 1, EVA with ethylene acetate content below 5%, its main products are film, wire and cable, LDPE modifier, adhesive and so on; 2, ethylene acetate content in 5%~10% EVA product is elastic film, 3, ethylene acetate content in 20~28% EVA, mainly used in hot melt adhesives and coating products; EVA is from LLDPE (linear low density) Polythene) and acetic acid (VA) copolymerization.
LLDPE也是通過化學改性得來的。它是在聚合中引入丁烯、、辛烯等少量的a-烯烴類單體而形成的共聚物。它具有與HDPE類似的分子構型,但了密度和結晶度。LLDPE有良好的耐應力開裂性,其機械性能也優于LDPE,因此,其應用范圍也相應地擴大了。而氯化聚(CPE)也是化學改性的產物。
LLDPE is also chemically modified. It is a copolymer formed in ethylene polymerization by introducing a small amount of a- olefin monomers, such as butene, hexene and octene. It has a molecular configuration similar to HDPE, but reduces the density and crystallinity. LLDPE has good resistance to environmental stress cracking, and its mechanical properties are superior to LDPE. Therefore, its application scope has expanded correspondingly. Chlorinated polyethylene (CPE) is also a product of chemical modification.
HDPE通過氯化后的產物。氯(CL)部分取代HDPE分子中的氫(H),使分子受到結晶性,從而使它更,并有一定的彈性。它不僅可以用擠出或注塑等加工成CPE制品,廣泛用于建筑、電器等方面,而且CPE本身成為一種優良的改性劑,可以通過物理共混的PE材料的阻燃性和PVC材料的抗沖擊性。
HDPE passes the product after chlorination. Chlorine (CL) partially replaces the hydrogen (H) in the HDPE molecule, causing the molecules to be destroyed by crystallization, it softer and more flexible. It can not only be processed into CPE products by extrusion?or?injection molding, but also widely used in construction and electrical appliances, and CPE itself becomes a fine modifier. It can improve the flame retardancy of PE materials and the impact resistance of PVC materials by physical blending.
PA66的收縮率在1%~2%之間,加入玻璃纖維添加劑可以將收縮率到0.2%~1% 。收縮率在流程方向和與流程方向相垂直方向上的相異是較大的。PA66對許多溶劑具有抗溶性,但對酸和其它一些氯化劑的抵抗力較弱。
The shrinkage of PA66 is between 1%~2%, and the addition of glass fiber can reduce the shrinkage to 0.2%~1%. The shrinkage rate is different from that in the vertical direction of the flow direction. PA66 is resistant to many solvents, but is less resistant to acids and other chlorinated agents.
