Iingenelo kunye nokungonakali kokusebenza komtya wokutywina kuchaphazela ukungangeni komoya, ukumelana namanzi, ukulahleka kobushushu kunye nezinye izalathisi ezibalulekileyo zokusebenza kweengcango kunye neefestile zeengcango zesakhiwo kunye neefestile ukuya kumlinganiselo omkhulu, kunye nokuqina kweengcango kunye neefestile. Ngenxa yesi sizathu, ilizwe liye laqulunqa umgangatho wesizwe we-GB12002-89 "umnyango wePlastiki kunye nefestile yefestile" ixesha elide ukulungelelanisa ukuveliswa kunye nokuhlolwa kwezitywina.
Nangona kunjalo, umgangatho wangoku kunye nexabiso lerabha kunye neeplastiki zokutywina iingcango kunye neefestile kwimarike yezinto zokwakha zidideka kakhulu. Iyabiza kwi-15,600 yeeyuan ngetoni nganye, kodwa inexabiso eliphantsi nge-6,000 yeeyuan ngetoni nganye. Umahluko wamaxabiso uphantse ube yi-yuan eyi-10,000, kwaye umgangatho uyahluka kakhulu. Wonke umntu uyayazi into amakayenze. Abavelisi abaninzi baye baxela ukuba isitywina sabo kukuphunyezwa komgangatho wesizwe we-GB12002-89, kwaye ingxelo yovavanyo olufanelekileyo inokukhutshwa yi-arhente egunyazisiweyo. Ngokwezitywina zerabha zabavelisi abaziwayo abasetyenziswa yinkampani yethu ngoku kweli shishini, kunye neesampulu zokutywina ezikhutshwe ngabavelisi, ukusebenza koguga komoya oshushu kule projekthi kunefuthe elimangalisayo kwisalathiso sokunciphisa ubunzima bokufudumeza: iisampuli ezingaphezu kwe-10, enyanisweni, akukho namnye umntu ofanelekileyo.
Ngokomgangatho we-GB12002-89, into yokusebenza yokuguga yomoya oshushu yomgca wokutywina kufuneka ibe yi-3% kwisalathisi sokunciphisa ubunzima bokufudumala. Nangona kunjalo, ukulahlekelwa kwesisindo sokufudumala kweziphumo zovavanyo lwangempela yi-7.17% ~ 22.54%, ekude ngaphaya komgangatho welizwe jikelele.
Kwimicu yokutywina okunjalo, inani elikhulu leeplastiki eziphantsi abilayo okanye i-plasticizer substitutes zongezwa kwifomula. Olu hlobo lwetywina lusaguquguquka kakhulu kwixesha elitsha. Nangona kunjalo, njengoko ixesha lihamba, i-plasticizer iyancipha ngakumbi, i-elasticity yokutywina ilungile, kwaye iyancipha kwaye iyancipha, echaphazela ukusebenza kokutywinwa kwimpembelelo yempembelelo yomnyango kunye nefestile, kwaye iphinda ithintele ukuqina komnyango kunye nendibano yefestile.
Ukongezelela, umxholo we-plasticizer we-sealant uphezulu kakhulu, kwaye udibanisa ne-migration phenomenon ye-PVC resin ngexesha lokusetyenziswa kwe-plasticizer. Ibangela umthunzi wefreyimu yasekhaya kunye nokudumba. Oko kukuthi: xa udibana nesitywina kwindawo yokutywina, kukho ububanzi obubanzi kwaye buncinci, obungaxutywanga, ibala elimnyama, kunye nomzimba omhlophe wenza umehluko oqinileyo, ochaphazela kakhulu ukubonakala. Umbala kwi-plasticizer ngenxa yokufuduka, kunye nokuvuvukala kwendawo. (Iingcango ze-Sliding kunye neefestile azibonakali ngenxa yoqhagamshelwano kunye neeprofayili zamacandelo, kwaye iiprofayili zinemibala kwaye zidumbile. Ngokuqhelekileyo, iingcango ezivulekileyo kunye neefestile azikwazi ukubonwa kwimeko evulekileyo. Isitywina kunye neeprofayili ezihambelanayo ziye zaphelelwa ngumfowunelwa.) Nangona iiprofayili zendawo kunye nokudumba azinayo imiphumo enzulu yokungaphumeleli kweprofayili yefestile kunye neefestile zeplastiki kunye neefestile zefestile kunye neefestile ezinzulu. Emva kwayo yonke loo nto, esi sisiphako, emva kwayo yonke loo nto, umphumo wemifanekiso yeengcango zeplastiki kunye neefestile zimbi kakhulu.
Ukuze kugcinwe umfanekiso weengcango zeplastiki kunye neefestile kunye nokukhathalela ukukhula okunempilo kunye nokuqina kolu shishino olusakhulayo, abavelisi bemicu yokutywina kufuneka bavelise amatywina afanelekileyo ngokwenene, kunye nomnyango weplastiki kunye nezityalo zokuhlanganisa iifestile kufuneka zisebenzise amatywina asemgangathweni ophezulu ngokwenene.
