1. Izinto ezahlukene
PP amapotimendekukhona polypropylene resins.Ngenxa yokuthi i-homopolymer PP i-brittle kakhulu uma izinga lokushisa lingaphezu kuka-0C, izinto eziningi ze-PP zokuhweba zingama-copolymer angahleliwe ane-ethylene engu-1~4% engeziwe noma ama-clamp anokuqukethwe okuphezulu kwe-ethylene.ifomula copolymer.
I-PC epotimendeni le-PC ibizwa ngokuthi "i-polycarbonate".I-Polycarbonate iyinhlaka eqinile ye-thermoplastic ethola igama layo emaqenjini e-CO3 ngaphakathi kuyo.Nge-bisphenol A kanye ne-carbon oxychloride synthesis.Indlela esetshenziswa kakhulu i- melt transesterification method (i-bisphenol A kanye ne-diphenyl carbonate ahlanganiswa nge-transesterification kanye ne-polycondensation).
2. Izici ezahlukene
Ipotimende le-PP: Impahla ye-PP yohlobo lwe-copolymer inezinga lokushisa eliphansi lokuhlanekezela okushisayo (100C), ukukhanya okuphansi okuphansi, i-gloss ephansi, ukuqina okuphansi, kodwa inamandla omthelela anamandla.Amandla e-PP ayanda ngokukhula kokuqukethwe kwe-ethylene.Izinga lokushisa le-Vicat lokuthambisa le-PP lingu-150C.Ngenxa yezinga eliphakeme le-crystallinity, le nto inokuqina okuhle kwendawo kanye nezakhiwo zokumelana nokunwaya.
Ipotimende le-PC: Kuyi-amorphous thermoplastic resin enezici ezinhle kakhulu ezihlanganisayo, ene-insulation kagesi enhle kakhulu, ubude, ukuzinza kwe-dimensional kanye nokumelana namakhemikhali, amandla aphezulu, ukumelana nokushisa nokumelana nokubanda;futhi inezicisha ngokwakho, i-flame retardant, non-toxic, colorable, njll.
3. Amandla ahlukene
Ipotimende le-PP: inamandla okuthonya anamandla.Ukuqina kobuso kanye nezakhiwo zokumelana nokunwaya zalesi sici zinhle kakhulu.
I-PC suitcase: Amandla ayo angahlangabezana nezidingo ezihlukahlukene kusukela kumakhalekhukhwini kuya engilazini engangenwa izinhlamvu.Uma kuqhathaniswa nensimbi, ubulukhuni bayo abanele, okwenza ukubukeka kwayo kube lula ukuklwebheka, kodwa amandla nokuqina kwayo kuhle kakhulu, kungakhathaliseki ukuthi ukucindezela okunzima noma okujwayelekile , inqobo nje uma ungazami ukuyinyakazisa, yinde ngokwanele.
