I-polypropylene homopolymer

I-Polypropylene iyinto eyongayo enikeza inhlanganisela yezinto ezibonakalayo ezibonakalayo, ezomshini, ezishisayo, nezikagesi ezingatholakali kunoma iyiphi enye i-thermoplastic.Uma iqhathaniswa ne-polyethylene esezingeni eliphansi noma ephezulu, inamandla omthelela ophansi, kodwa izinga lokushisa eliphakeme lokusebenza namandla aqinile.Yaziwa ngokumelana kwayo okuhle kakhulu namakhemikhali ezindaweni ezonakalisayo, i-polypropylene inikeza ukumelana okuhle kakhulu nezinyibilikisi zemvelo, ama-agent okwehlisa amafutha kanye nokuhlasela kwe-electrolytic.Inesisindo esincane, imelana nokungcoliswa, futhi inezinga eliphansi lokumunca umswakama.

I-Polypropylene itholakala ngezinhlobo ezimbili eziyisisekelo njenge-homopolymer noma i-copolymer material.Nakuba okufanayo ezicini eziningi uhlobo ngalunye lubonisa umehluko ohlukile kukho kokubili ukubukeka nokusebenza.

I-Polypropylene Homopolymer (PPH) isetshenziswa kabanzi.I-PPH inikeza isilinganiso samandla aphezulu esisindweni futhi iqinile futhi inamandla kune-copolymer, lokhu kuhlangene nokumelana okuhle kwamakhemikhali kanye nokushisela kuvumela lokhu okubalulekile ukuthi kusetshenziswe ezakhiweni eziningi ezimelana nokugqwala.

I-Polypropylene copolymer (PPC) ithe ukuthamba kancane kodwa inamandla omthelela angcono, iqinile futhi ihlala isikhathi eside kune-PPH.I-copolymer polypropylene ijwayele ukuba nokumelana kangcono nokuqhekeka kwengcindezi kanye nokuqina kwezinga lokushisa eliphansi kune-homopolymer ngezindleko zokuncipha okuncane kwezinye izakhiwo.

IZIMPAHLA

QAPHELA: Amanani esakhiwo ethulwe ngenhla amanani ajwayelekile ahloselwe ireferensi nezinjongo zokuqhathanisa kuphela.AKUMELE zisetshenziswe njengesisekelo sokucaciswa kwedizayini noma ukulawulwa kwekhwalithi.
