Ishidi le-PP elivimbela ilangabi liyishidi lepulasitiki elenziwe nge-resin ye-PP, elinezithasiselo ezahlukahlukene ezisebenzayo ezingeziwe ngokusebenzisa i-extrusion, i-calendar, i-cooling, i-cutting kanye nezinye izinqubo. Ishidi le-PP elivimbela ilangabi liyizinto ezi-semi-crystalline. Liqinile kune-PE futhi linephuzu lokuncibilika eliphakeme. Ngenxa yokuthi izinga lokushisa le-PP le-homopolymer lithambile kakhulu ngaphezu kwe-0C, izinto eziningi ze-PP zezentengiselwano ziyi-copolymers ezingahleliwe ezinokuqukethwe kwe-ethylene okungu-1-4% noma ama-block copolymers anokuqukethwe kwe-ethylene okuphezulu. Izinto ze-PP ze-Copolymer zinezinga lokushisa eliphansi lokuphambuka kokushisa (100°C), ukucaca okuphansi, ukukhanya okuphansi, kanye nokuqina okuphansi, kodwa zinamandla amakhulu okuthinta. Ngakho-ke, ungayibona kanjani ikhwalithi yeshidi le-PP elivimbela ilangabi?
1. Hlola ukucwebezela kwayo okungaphezulu. Ukucwebezela okubi kuyipulasitiki ephinde yasetshenziswa.
2. Qaphela ukuqina kwayo. Ishidi le-PP elisebenzisa ilangabi elihlanzekile linokuqina okuhle kakhulu futhi lingagobeka kancane.
3. Hlola indawo yokusika. Ngemva kokusika ipulasitiki ephinde yasetshenziswa, kuzoba nezinhlobonhlobo zemfucumfucu enemibala ehlukene.
4. Hlola ubuningi bayo. Ubuningi be-PP polypropylene bungu-0.92 ~ 0.93. Zonke izinto ezintanta emanzini ziyi-polypropylene.
5. Ishidi le-PP elivimbela ilangabi liyashiswa futhi lishiselwe. Intuthu iyaphuma lapho kushiswa ipulasitiki esetshenzisiwe.
6. Ukudlulisa ukukhanya, amapulasitiki aphinde asetshenziswa awadlulisi ukukhanya kahle.
7. Ukuqina, ipulasitiki ephinde yasetshenziswa nakho kubi kakhulu.
8. Ubuningi beshidi le-PP elivimbela ilangabi, liphonse emanzini ukuze ubone ukuthi liyantanta yini emanzini, iningi lamanzi asetshenziswe kabusha liyashona phansi.
