Emhlabeni wokukhiqizwa kwamapulasitiki, ukukhethwa kwezinto zokusetshenziswa kudlala indima ebalulekile ekunqumeni impumelelo nokuqina komkhiqizo wokugcina. Amagranule e-PVC aqinile wokubumba nge-injection angaphakathi kwezinto ezibaluleke kakhulu ezisetshenziswa ezimbonini ezahlukahlukene ngenxa yokusebenza kwawo okuhlukahlukene, amandla, nokonga izindleko. Ukukhetha amagranule e-PVC aqinile wokubumba nge-injection asezingeni eliphezulu kuqinisekisa ukusebenza okuthembekile, ukucubungula okulula, kanye nekhwalithi engcono yomkhiqizo wokugcina. Ezinkampanini ezifuna ukuthuthukisa umkhiqizo wazo wokukhiqiza futhi zihlangabezane nezidingo zezicelo ezahlukahlukene, ukuqonda inani lamagranule asezingeni eliphezulu kubalulekile. Lesi sihloko sihluza izici, izicelo, nezinketho zokwenza ngokwezifiso zamagranule e-PVC aqinile wokubumba nge-injection, sigcizelela ukuthi kungani ikhwalithi ibaluleke ngempela kule ndawo.

Izinhlamvu ze-PVC eziqinile zokubumba nge-injection yizinhlamvu ezincane ezenziwe nge-polyvinyl chloride, ezilungiselelwe ngokukhethekile izinqubo zokubumba nge-injection. Lezi zinhlamvu zihlukaniswa ngokuqinile kwazo, amandla aphezulu emishini, nokumelana kahle namakhemikhali. Ngokungafani ne-PVC ethambile, izinhlamvu ze-PVC eziqinile zine-plasticizers encane, okuholela emikhiqizweni eqinile, eqinile, futhi ekwazi ukumelana nokucindezela kwemishini. Izimfanelo zazo zomzimba ziyenza ilungele izicelo ezidinga ukuzinza nokuphila isikhathi eside. Izici ezibalulekile zihlanganisa amandla aphezulu okudonsa, ukumelana nokushayeka nokukhuhleka, nokuzinza kwe-thermal, okuvumela ukuthi zisebenze kahle ngaphansi kwezimo ezahlukene zemvelo. Lapho ukhetha izinhlamvu ze-PVC eziqinile zokubumba nge-injection, izinto ezifana nokuhlanzeka, i-melt flow index, nokufana kwezinhlamvu kubalulekile ukuqinisekisa izinqubo zokubumba ezibushelelezi kanye nekhwalithi yomkhiqizo engaguquki.

Amagranule okubumba omjovo we-PVC aqinile asetshenziswa kabanzi ezimbonini ngenxa yokuqina kwawo nokwazi ukuzivumelanisa nezimo. Ekwakheni, avame ukusetshenziselwa ukukhiqiza amapayipi, amafreyimu amafasitela, nezingxenye zokuxhuma, ezizuzwa ngokumelana kwawo nokugqwala nokukhanya kwe-UV. Imboni yokupakisha isebenzisa kakhulu la magranule ekukhiqizeni izitsha eziqinile nezingxenye zokuvikela, lapho ukuzinza kobukhulu nokuqina kubaluleke kakhulu. Ngaphezu kwalokho, umkhakha wezimoto usebenzisa i-PVC eqinile ezintweni zangaphakathi nezingxenye zokuhlobisa, usebenzisa ubukhulu bayo obulula kodwa obuqinile. Ezinye izinto ezisetshenziswa ezimbonini zihlanganisa izindlu zamadivayisi kagesi, amadivayisi ezokwelapha, kanye nezimpahla zabathengi, lapho ukumelana namakhemikhali kwamagranule kanye nokulula kwawo ekucubunguleni kunomthelela ekusebenzeni okungcono komkhiqizo. Ukusebenza okuhlukahlukene kwamagranule okubumba omjovo we-PVC aqinile kubenza bakhethwe kabanzi emikhakheni eyahlukene yemakethe.

Amaphuzu okuthambisa kwe-Vicat kuyisici esibalulekile sokuhlola izici zokushisa zamagranule e-PVC aqinile omjovo. Kubhekiselwa ezingeni lokushisa lapho impahla iqala ukuthamba ngaphansi komthwalo ocacisiwe, okunikeza ukuqonda ekumeleni kwayo ukushisa nemikhawulo yokusebenza. Iphuzu eliphezulu lokuthambisa kwe-Vicat libonisa ukuzinza okungcono kokushisa, okuhumusha ekusebenzeni okuthuthukisiwe ezinhlelweni ezivezwe emazingeni okushisa aphakeme. Ukuqonda leli phuzu kusiza abakhiqizi ukuthi babikezele ukuthi ipulasitiki izoziphatha kanjani ngesikhathi sokubunjwa nangokusebenzisa kwangempela, baqinisekise ukuthi imikhiqizo ihlangabezana namazinga okuphepha nokuqina. Ukuqapha iphuzu lokuthambisa kwe-Vicat kubalulekile ekulawuleni ikhwalithi, njengoba kuthinta izimo zokubunjwa nokuqina kwesikhathi eside kwezingxenye ezibunjwe.

Enye yezinzuzo zamagranules e-PVC aqinile omjovo ukukwazi ukwenza ngezifiso izakhiwo zawo ukuze zihambisane nezidingo ezithile zokukhiqiza. Abakhiqizi bangalungisa izinga lokuqina ngokuguqula ifomula, okuvumela imikhiqizo ukuthi isukume kusuka ku-semi-rigid kuye kuya ku-fully rigid ngokusekelwe ezidingweni zokugcina. Ukwenza ngezifiso umbala nakho kunikezwa kabanzi, okuvumela ukukhiqizwa kwamagranules ngemibala ehlukahlukene ukuze kuhlangatshezwane nezidingo zobuhle noma zokukhangisa ngaphandle kokudela ubuqotho bezinto. Izithako zingafakwa ukuze kuthuthukiswe ukumelana nomlilo, ukumelana ne-UV, noma amandla okumelana nomthelela. Leli zinga lokwenza ngezifiso liqinisekisa ukuthi amabhizinisi angathola amagranules e-PVC ahambisana kahle nemininingwane yomkhiqizo wawo, kuthuthukiswe ukusebenza kahle nokuncintisana emakethe. Izinkampani ezifana neHebei Jiayuan Plastic Products Co., Ltd. ikhethekile ekunikezeni lezi zixazululo ezihlelwe, ixhasa amakhasimende ngemikhiqizo ye-PVC esezingeni eliphezulu, engashintshwa.

Ukukhetha umphakeli onokwethenjelwa wezinhlamvu ze-PVC rigid injection molding kubaluleke njengokuba nekhwalithi yempahla uqobo. Abaphakeli abathembekile bagcina izinqubo eziqinile zokulawula ikhwalithi ukuze baqinisekise ukungaguquguquki nokusebenza kwezinhlamvu zabo. Bahlinzeka ngamashidi emininingwane yezobuchwepheshe, basize ekukhetheni umkhiqizo, futhi banikeze ukwesekwa ngemuva kokuthengisa, okwenza inqubo yokuthenga ibe bushelele futhi ibe sobala. Abaphakeli abanamandla okukhiqiza azinzile nendlela egxile kumakhasimende bathuthukisa ukwethembana nobudlelwano besikhathi eside. Ngokwesibonelo,Hebei Jiayuan Plastic Products Co., Ltd. iyaziwa ngokuzinikela kwayo ekwaneliseni ikhwalithi kanye nekhono lokusebenza ekunikezeni ama-granules e-PVC aqinile okufaka. Ukubambisana nalezi zimpahla kuqinisekisa ukuthi abakhiqizi banokufinyelela ezinsizeni eziphezulu ezisekelwa ubuchwepheshe obunembile kanye nezokuthutha ezithembekile.

Ngokuphetha, ama-granule okubumba nge-PVC aqinile ngokujova ayisisekelo ekukhiqizeni imikhiqizo yepulasitiki eqinile, enokusebenza okuphezulu ezimbonini eziningi. Ikhwalithi yala ma-granule ithinta ngqo kalula ukucubungula, ukwethembeka komkhiqizo, nokusebenza okuhlukahlukene kwezicelo. Ukuqonda izici eziyinhloko njengezici zawo zemishini, iphuzu lokuthamba le-Vicat, nezinketho zokwenza ngokwezifiso kuhlomisa abakhiqizi ukuthi benze izinqumo zokuthenga ezinekhono. Ngaphezu kwalokho, ukukhetha umphakeli ohlonishwayo njengoHebei Jiayuan Plastic Products Co., Ltd. kuqinisekisa ukufinyelela kwekhwalithi ehambisanayo, ukwesekwa kwezobuchwepheshe, nezixazululo ezenziwe ngokwezifiso ezihlangabezana nezidingo zemakethe eziguqukayo. Ezinkampanini ezifuna ukusebenzisa izinzuzo ze-PVC rigid injection molding granules, ukutshala imali ezintweni ezisezingeni eliphezulu kuyisisekelo sempumelelo.

Hlola okwengeziwe mayelana nemikhiqizo ye-PVC esezingeni eliphezulu nezixazululo zokufaka ngokuvakashela ku-Imikhiqizo ikhasi, noma uxhumane nochwepheshe ngalesi Ukuxhaswa isigaba sokuthola usizo olwenziwe ngokwezifiso.
