1. Umehluko ekusetshenzisweni.
Isikali sokusetshenziswa kweIphepha le-PE: esetshenziswa kabanzi embonini yamakhemikhali, imishini, imboni yamakhemikhali, ugesi, izingubo zokugqoka, ukupakisha, ukudla kanye neminye imisebenzi. Isetshenziswa kabanzi ekuthuthweni kwegesi, ukuhlinzekwa kwamanzi, ukukhishwa kwendle, ukuchelela ngenkasa kwezolimo, ukuthutha okuqinile kwezinhlayiyana ezimayini, kanye nensimu kawoyela, imboni yamakhemikhali, iposi kanye nezokuxhumana, njll., ikakhulukazi ekuthuthweni kwegesi.
Isilinganiso sokusetshenziswa kwepuleti le-PP: okokusebenza okumelana ne-asidi ne-alkali, okokuvikela imvelo, amanzi angcolile nezinto zokulahla igesi engcolile, umbhoshongo wokukhuhla, igumbi elingenalo uthuli, okokusebenza kwefekthri ye-semiconductor nezimboni ezihambisana nayo, kanye nezinto ezikhethwayo zokwenza ithangi lamanzi lepulasitiki. Ngalesi sikhathi, ipuleti eliwugqinsi le-PP lisetshenziswa kabanzi ukugxiviza ipuleti, ipunch pad, njll.
2. Umehluko ngezici.
Ibhodi le-PE lithambile futhi linokuqina okuthile, futhi ukumelana kwayo komthelela nokusebenza kwe-cushioning kungcono, lapho ibhodi elibunjiwe linokusebenza okungcono; Ibhodi le-PP linobulukhuni obuphezulu, izakhiwo ezingezinhle zemishini, ukuqina okuphansi kanye nokumelana nomthelela omubi.
3. Umehluko ezintweni.
Ipuleti le-PP, elaziwa nangokuthi ipuleti le-polypropylene (PP), liyi-semi-crystalline material. Iqinile kune-PE futhi inephuzu lokuncibilika eliphakeme. Ishidi le-PE liwuhlobo lwe-thermoplastic resin ene-crystallinity ephezulu kanye ne-non-polarity. Ukubukeka kwe-HDPE yasekuqaleni kumhlophe qhwa, futhi ishintshashintsha ngokwezinga elithile esigabeni esincanyana.
Isikhathi sokuthumela: Feb-09-2023
