Uma kukhulunywa ngokukhetha izinto ezifanele iphrojekthi yakho, ukukhetha phakathi kwamaphepha e-PP namashidi e-PPH kudlala indima ebalulekile. Ngenkathi zombili izinketho ziphumelela ezinhlelweni ezahlukene, ukuqonda izakhiwo zazo ezihlukile nezici kubalulekile. Kulesi sihloko sebhulogi, sizohlola izici, izinzuzo, kanye nezimo zokusetshenziswa ezingcono kakhulu zephrojekthi yakho.Ishidi le-PPkanyeIshidi le-PPHs.
I-PolypropyleneAmashidi (PP) aziwa ngamandla awo akhethekile, ukuqina, kanye nokuguquguquka. Lawa mashidi alula anikeza ukumelana okuhle kwamakhemikhali, okwenza abe afanele ukusetshenziswa kwezimboni nezentengiselwano. Amashidi e-PP asetshenziswa kabanzi ezimbonini zokupakisha, zezimoto, kanye nezimpahla zabathengi, ikakhulukazi ngenxa yokumuncwa kwawo umswakama omncane kanye nokumelana nokushaywa kanye nokuklwebheka. Lawa mashidi aziwa nangokumelana kwawo nama-asidi, izisekelo, kanye nezinyibilikisi.
Amashidi e-polypropylene homopolymer (PPH) afana kakhulu namashidi e-PP, kodwa anezici ezithile ezihlukile.Ishidi le-PPHAma-s anezinga eliphakeme lokuqina namandla, okwenza afaneleke kakhulu ekusetshenzisweni okudinga amandla athuthukisiwe. Abonisa ukumelana nokushisa okuhle kakhulu, anikeza ukusebenza okuhle kakhulu ezindaweni ezishisa kakhulu. Ngaphezu kwalokho, amashidi e-PPH ayamelana nokuqhekeka futhi abonisa ukumelana kwamakhemikhali isikhathi eside okuphezulu.
Uma kuqhathaniswa amashidi e-PP namashidi e-PPH, kuba sobala ukuthi izakhiwo zawo kanye nezici zokusebenza ziyawahlukanisa. Ngenkathi zombili izinto zinobuhle obufanayo njengokumelana namakhemikhali nokuqina, amashidi e-PPH anikeza amandla angcono omshini kanye nokumelana nokushisa uma kuqhathaniswa namashidi e-PP. Ngakho-ke, amashidi e-PPH avame ukuthandwa lapho kusetshenziswa khona ukuqina okwengeziwe nokuqina.
Ekuphetheni, ukukhetha phakathiIshidi le-PPAmashidi e-s kanye ne-PPH ancike ekuqondeni izidingo ezihlukile zephrojekthi yakho. Cabanga ngezinto ezifana nokumelana namakhemikhali, amandla omshini, kanye nokumelana nokushisa ukuze wenze isinqumo esinolwazi.
