Ithini indwangu yePolyPropylene?

Ilaphu le-polypropylene ligama elisetyenziselwa ukuchaza nayiphi na imveliso yemboniselo ethathwe kwi-Thermoplastic Polymer Polymer Polyplene. Olu hlobo lweplastiki luyinxalenye yeqela lePolycofin, kwaye ayisiyo-polar kunye ne-crystalline. Ecaleni kwePolythylene, iPolypropylene yeyona iplastiki yesibini ye-Special kwihlabathi, kwaye iqhele ukusetyenziswa ngokufakelwa, imigudu, kunye nezinye iintlobo zabathengi kunye neempahla zemizi-mveliso kunangaphambili.

Olu hlobo lweplastiki lwaluphuhliswa yi-Pillies America Pillips Petroleum ngo-1951. I-Chemisers Robert Banks kunye ne-Jus Hogar yayizama ukufumana i-perline ukusuka kwi-proplelene, kwaye ngengozi yadalwa ngengozi. Ngelixa olu luvavanyo lwalubizwa ngokuba kukusilela, kwavunywa ngokukhawuleza ukuba le ngqokelela intsha inokubakho kwi-polyethylene kwizicelo ezininzi.

Kwakungekho kude kube ngo-1957, nangona kunjalo, ukuba i-polypropyyylene yenziwa into efanelekileyo kwimveliso yobuninzi. Ngo-1954, i-Chelist yase-Italiyane Giulio Natta kunye neqabane lakhe lwaseJamani laphumelela ukwenza le nto ibe yi-polymer ye-Ismotmer, kwaye i-Italiya yaseMonteCatini ikhawuleza yaqala ukuvelisa le nto ukuba isetyenziswe le nto ukuze isebenze le nto ukuze isetyenziswe le nto ukuze kusetyenziswe le nto.

I-Polypropylene yathengiswa phantsi kwegama "Mongan," kwaye eli gama liselithengisa intengiso ebhalisiweyo yeLongollbasell Iqumrhuli. Nangona kunjalo, kuxhaphake kakhulu ukufumana le nto ibhekiswe kuyo njenge-polyproplene okanye i "polypro" emfutshane.
