1, umehluko ekusetshenzisweni.
Isikali sokusetshenziswa kweIshidi le-PE: isetshenziswa kabanzi embonini yamakhemikhali, imishini, imboni yamakhemikhali, amandla kagesi, izingubo, ukupakisha, ukudla kanye neminye imboni. Isetshenziswa kabanzi ekuthuthweni kwegesi, ekuhlinzekweni kwamanzi, ekukhishweni kwendle, ekuniseleni kwezolimo, ekuthuthweni kwezinhlayiya ezincane zemayini, ensimini kawoyela, embonini yamakhemikhali, eposini nasezokuxhumana kanye nakwezinye izinsimu, ikakhulukazi ekuthuthweni kwegesi.
Ububanzi bokusetshenziswa kweishidi le-pp: imishini evikela i-asidi ne-alkali, imishini yokuvikela imvelo, amanzi angcolile, imishini yokukhipha igesi engcolile, umbhoshongo wokuklwebha, igumbi elihlanzekile, imishini yezimboni ze-semiconductor kanye nezimboni ezihlobene, futhi futhi iyinto ekhethwayo yokwenza amathangi amanzi epulasitiki, phakathi kwawo asetshenziswa kabanzi amashidi amakhulu e-PP. Isetshenziselwa ukunyathela ipuleti, ipuleti lokubuyela emuva, njll.
2. Umehluko ezimfanelweni.
Ibhodi le-PEithambile, inokuqina okuthile, ukumelana okungcono kokuthinteka kanye nokusebenza kahle kokucushwa, futhi ukusebenza kwebhodi elibunjiwe kungcono; ibhodi le-PP linokuqina okuphezulu, izakhiwo ezimbi zemishini, ukuqina okuphansi, kanye nokumelana okubi kokuthinteka kanye nokucushwa.
3. Umehluko ezintweni zokwakha.
Ibhodi le-PP, eyaziwa nangokuthi ishidi le-polypropylene (PP), iyinto ewuketshezi oluyi-semi-crystalline. Iqinile futhi inezinga lokuncibilika eliphakeme kune-PE. Ishidi le-PE liyi-resin ye-thermoplastic ewuketshezi oluyi-crystalline kakhulu, engeyona i-polar. Ukubukeka kwe-HDPE yokuqala kumhlophe njengobisi, kanti ingxenye encane ikhanya ngezinga elithile.
Isikhathi sokuthunyelwe: Juni-28-2023
