Yiziphi izindlela zokugaywa kabusha kwamapulasitiki alahlwayo?
Kunezindlela ezintathu zokugaywa kabusha: 1. Ukwelashwa kokubola okushisayo: Le ndlela iwukushisa nokubola imfucuza yepulasitiki ibe uwoyela noma igesi, noma ukuyisebenzise njengamandla noma ukusebenzisa kabusha izindlela zamakhemikhali ukuwahlukanisa abe imikhiqizo ye-petrochemical ukuze isetshenziswe.Inqubo yokubola okushisayo yilezi: i-polymer iyancipha emazingeni okushisa aphezulu, futhi amaketanga e-molecular ayaphuka futhi abola abe ama-molecule amancane nama-monomers.Inqubo yokubola okushisayo ihlukile, futhi umkhiqizo wokugcina uhlukile, okungenzeka ube ngesimo se-monomer, i-polymer yesisindo samangqamuzana aphansi, noma ingxube yama-hydrocarbon amaningi.Ukukhethwa kwenqubo yokugcoba amafutha noma i-gasification kufanele kusekelwe ezidingweni zangempela.Izindlela ezisetshenziswayo yilezi: uhlobo lwethangi elincibilikayo (lwe-PE, i-PP, i-PP engahleliwe, i-PS, i-PVC, njll.), uhlobo lwe-microwave (PE, PP, i-PP engahleliwe, i-PS, i-PVC, njll.), uhlobo lwesikulufu (lwe-PE, PP , PS, PMMA).Uhlobo lwe-tube evaporator (ye-PS, PMMA), uhlobo lombhede ovuvukalayo (ye-PP, i-PP engahleliwe, i-PE exhunywe ngokuphambanayo, i-PMMA, i-PS, i-PVC, njll.), uhlobo lokubola kwe-catalytic (ye-PE, PP, PS, PVC, njll. ).Ubunzima obuyinhloko kumapulasitiki abola ngokushisa ukuthi amapulasitiki anokungahambi kahle kwe-thermal, okwenza ukubola kwezimboni ezinkulu kanye nokuqhekeka okushisayo kube nzima ukwenza.Ngaphezu kokubola okushisayo, kunezinye izindlela zokwelapha zamakhemikhali, njengokuqhekeka okushisayo, i-hydrolysis, i-alcoalysis, i-alkaline hydrolysis, njll., engabuyisela izinto zokusetshenziswa zamakhemikhali ahlukahlukene.
2. Ukuncibilika kabusha kweNcibilikisa Le ndlela iwukuhlunga, ukuchoboza, nokuhlanza amapulasitiki alahlwayo, bese ewancibilikisa futhi enziwe ngepulasitiki abe imikhiqizo yepulasitiki.Ngemikhiqizo kadoti nezinto ezisele ezivela ezimbonini zokukhiqiza inhlaka kanye nezitshalo zokucubungula nokukhiqiza zepulasitiki, le ndlela ingasetshenziswa ukukhiqiza imikhiqizo ehlukahlukene enekhwalithi engcono.Kunzima ukuhlunga nokuhlanza amapulasitiki angcolile asetshenziswa emphakathini, futhi izindleko ziphezulu.Ngokuvamile zisetshenziselwa ukwenza imikhiqizo eqinile futhi ephansi.3. Ukusetshenziswa kabusha kwenhlanganisela: Le ndlela iwukuphula amapulasitiki okulahlwayo, njengemikhiqizo yegwebu le-PS, igwebu le-PU, njll. abe yizicucu zosayizi othile, bese uwaxuba nezincibilikisi, izinto ezinamathelayo, njll. ukuze wenze amabhodi angasindi namalayini.
