Zeziphi iindlela zokurisayikilisha iiplastiki zenkunkuma?

Kukho iindlela ezintathu zokuphinda zisetyenziswe: 1. Unyango lokubola kwe-Thermal: Le ndlela kukufudumeza kunye nokutshabalalisa inkunkuma yeplastiki ibe yi-oyile okanye igesi, okanye isetyenziswe njengamandla okanye iphinde isebenzise iindlela zekhemikhali ukuzahlula kwiimveliso zepetrochemical ukuze zisetyenziswe.Inkqubo yokubola kwe-thermal yile: i-polymer depolymerizes kumaqondo okushisa aphezulu, kwaye i-molecular chain chain iqhekeza kwaye idibanise kwiimolekyuli ezincinci kunye ne-monomers.Inkqubo yokubola kwe-thermal iyahluka, kwaye imveliso yokugqibela iyahluka, enokuthi ibe luhlobo lwe-monomer, i-polymer ephantsi ye-molecular weight, okanye umxube wee-hydrocarbons ezininzi.Ukukhethwa kwe-oyile okanye inkqubo ye-gasification kufuneka isekelwe kwiimfuno zangempela.Iindlela ezisetyenziswayo zezi: uhlobo lwetanki enyibilikayo (ye-PE, i-PP, i-PP engaqhelekanga, i-PS, i-PVC, njl. njl.), uhlobo lwe-microwave (PE, PP, i-random PP, i-PS, i-PVC, njl.), uhlobo lwe-screw (ye-PE, i-PP , PS, PMMA).Uhlobo lwe-Tube evaporator (ye-PS, i-PMMA), uhlobo lwe-ebullating bed (ye-PP, i-PP engahleliwe, i-PE edibeneyo, i-PMMA, i-PS, i-PVC, njl.), uhlobo lwe-catalytic decomposition (ye-PE, PP, PS, PVC, njl. ).Obona bunzima kwiiplastiki zokubola kwe-thermal kukuba iiplastiki zine-conductivity ephantsi ye-thermal, eyenza i-industry-scale enkulu yokubola kwe-thermal kunye nokuqhekeka kwe-thermal kunzima ukwenza.Ukongeza kokubola kwe-thermal, kukho ezinye iindlela zonyango lwekhemikhali, njengokuqhekeka kwe-thermal, i-hydrolysis, i-alcolysis, i-alkaline hydrolysis, njl., enokubuyisela izinto ezahlukeneyo zemichiza ekrwada.

2. Ukunyibilika kusetyenziswe kwakhona Le ndlela kukulungisa, ukutyumza, kunye nokucoca iiplastiki ezilahlwayo, kwaye emva koko zinyibilike kwaye zenziwe zeplastiki zibe yimveliso yeplastiki.Kwiimveliso zenkunkuma kunye nezinto ezishiyekileyo ezivela kwizityalo zokuvelisa i-resin kunye nokulungiswa kweplastiki kunye nezityalo zemveliso, le ndlela ingasetyenziselwa ukuvelisa iimveliso ezahlukeneyo ezinomgangatho ongcono.Kunzima ukuhlenga nokucoca iiplastiki zenkunkuma ezisetyenziswa eluntwini, kwaye iindleko ziphezulu.Ngokuqhelekileyo zisetyenziselwa ukwenza iimveliso ezirhabaxa kunye nezisezantsi.3. Ukusetyenziswa kwakhona okuhlanganisiweyo: Le ndlela kukuqhekeza iiplastiki zenkunkuma, njengemveliso ye-PS ye-foam, i-pu foam, njl.njl. ibe ngamaqhekeza obungakanani obuthile, uze uwaxube kunye nezinyibilikisi, izinto zokuncamathelisa, njl.njl. ukwenza iibhodi ezikhaphukhaphu kunye ne-liners.
