Ukukhetha inqubo efanele yokubumba kuyisinqumo esibalulekile ekwenziweni kwezingxenye zepulasitiki. Ithinta ngqo izindleko zamathuluzi, izikhathi zomjikelezo wokukhiqiza, ikhwalithi yendawo, kanye nekhono lokuthola izilinganiso eziqondile. Amabhizinisi ahlose ukukhiqiza ngempumelelo kufanele aqonde izindlela ezahlukene zokubumba ezitholakalayo nokufaneleka kwazo ezinhlelweni ezahlukene. Lesi sihloko sihlinzeka ngokubuka konke okubanzi kwezinqubo ezibalulekile zokubumba ipulasitiki, imishini yazo, izinto zazo, kanye nezinto ezisebenzayo. Iphinde yethule uhlaka lwezinqumo ukusiza abakhiqizi bakhethe inqubo efanele kakhulu ngezidingo zabo ezithile.

Inqubo ngayinye yokubumba ipulasitiki inezinjongo ezihlukile zokukhiqiza, enezinto zokusebenza ezihlukile kanye nokuhambisana kwezinto. Izindleko zamathuluzi ziyahlukahluka kakhulu phakathi kwezinqubo futhi ngokuvamile zihambisana nomthamo wokukhiqiza okulindelekile. Ngaphezu kwalokho, ubujometri bengxenye bungakuvimbela ukukhetha indlela yokubumba, njengoba amanye amasu ebhekana kahle nezimo eziyinkimbinkimbi kunezinye. Ukuthuthukisa uhlaka oluhlelekile lokwenza izinqumo kubalulekile ukuze kuhambisane izinjongo zokukhiqiza nobuchwepheshe obufanele bokubumba, kuqinisekiswe ukonga izindleko kanye nekhwalithi yomkhiqizo.

Ukwelashwa komjovo kubandakanya ukujova ipulasitiki eshisiwe emishini enembayo kusetshenziswa imishini ekhethekile equkethe iyunithi yokujova, iyunithi yokubopha, namathuluzi. Izinto ezivamile zihlanganisa i-polypropylene (PP), i-acrylonitrile butadiene styrene (ABS), i-polystyrene (PS), i-high-density polyethylene (HDPE), ne-nylon. Le ndlela ihamba phambili ekukhiqizeni izixhumi, izindlu, amagiya, nezingxenye zezokwelapha ezinezimvume eziqinile nokusebenza kahle kwevolumu ephezulu. Kodwa-ke, ukwelashwa komjovo kudinga izindleko eziphakeme zokuqala zamathuluzi futhi kunamathele emithethweni eqinile yokuklama.

I-Blow molding yindlela lapho ipulasitiki eshisayo ivuvukiswa khona ngaphakathi kwesikhunta ukuze kwakhiwe izingxenye ezingenalutho. Imishini ngokuvamile yakhiwa yi-extruder noma iyunithi lokujova elihlanganiswe nesiteshi sokuvuvukisa. Izinto ezifana ne-HDPE, i-low-density polyethylene (LDPE), i-PP, ne-polyethylene terephthalate (PET) zivame ukusetshenziswa. Le ndlela ilungele ukukhiqiza imikhiqizo engenalutho elula njengamabhodlela, izigubhu, namathangi. Imikhawulo ihlanganisa ukuhluka kokuqina kodonga kanye nobunzima obukhawulelwe bezingxenye.

Ukubumba nge-Extrusion kuqhubeka nokucindezela ipulasitiki eshisayo ngokusebenzisa i-die enesimo ukuze kwakheke izimo. Le nqubo ihlanganisa i-extruder, i-die, kanye nezinhlelo zokupholisa futhi isebenza kahle ngezinto ezifana ne-polyethylene (PE), PP, polyvinyl chloride (PVC), kanye ne-polyethylene terephthalate glycol (PETG). Ilungele imikhiqizo eqhubekayo ende njengepayipi, amashidi, kanye nezimo. Izinselelo zihlanganisa ukuphatha ukushintsha kobukhulu kanye nokunciphisa imiphumela ye-die swell.

Engxenyeni yokubumba ngokucindezela, izinto ezilinganiselwe kusengaphambili zifakwa esikhunjeni esishisayo bese zibunjwa ngaphansi kwengcindezi kusetshenziswa ama-pressi we-hydraulic noma we-mechanical. Izinto ezivamile zihlanganisa ama-plastic we-thermoset nezinhlanganisela zerabha. Le nqubo ithandwa kakhulu izingxenye zezimoto ezinezindonga ezijiyile kanye nezindlu zikagesi. Ngenkathi ukubumba ngokucindezela kusekela ama-composites kahle, kuhlanganisa izikhathi ezinde zokujikeleza kanye nomkhawulo wokukwazi ukwenza imininingwane eyinkimbinkimbi.

Ukubumba nge-rotational kubumba izingxenye ngokushisa nokujikeleza impushana yepulasitiki ngaphakathi kwezikhumba. Kusetshenziswa umshini we-rotomolding onezikhumba eziklanyelwe ngokukhethekile, ikakhulukazi nge-linear low-density polyethylene (LLDPE). Ifaneleka kahle ekwenzeni izimo ezinkulu ezingenalutho njengamathangi, izitsha, kanye neziqukathi. Ububi obuyinhloko buhlanganisa izikhathi ezinde zokukhiqiza kanye nokunemba okuphansi kancane uma kuqhathaniswa nezinye izindlela.

I-Thermoforming ifudumeza amashidi epulasitiki futhi ayenze phezu kwezikhunta isebenzisa i-vacuum noma ingcindezi. Izinto zokusebenza zihlanganisa izifudumezi zamashidi neziteshi ze-vacuum noma zengcindezi. Izinto ezifana ne-ABS, i-high-impact polystyrene (HIPS), ne-PVC zivame ukwenziwa zibe amatheyi nezindlu. Lezi zinqubo zisebenza kahle ngokomnotho ekukhiqizeni okumaphakathi kodwa zinomkhawulo ekunembeni kwemininingwane kanye nokufana kobukhulu bodonga.

Isithombe esibukezayo sezinkqubo eziyinhloko zokubumba ipulasitiki.

Lapho ukhetha inqubo yokubumba, abakhiqizi kufanele bacabangele ubuchwepheshe bezinto zokusebenza, izindleko zamathuluzi, ukuzivumelanisa kwezinto ezibumbekile, amandla okubekezelelana, nezikhathi zokujikeleza. Ukubumba ngomjovo kuholela ekunembeni nasekucekeleni okusheshayo kodwa kufuna utshalomali olukhulu lwamathuluzi. Ukubumba ngomoya nokubumba okujikelezayo kugxile ezingxenyeni ezingenalutho ngezindleko eziphansi zamathuluzi kodwa kuhluleka ekunembeni. Ukubumba ngokukhipha akufani nezingxenye eziqhubekayo, kanti ukubumba ngokucindezela kugqama ezingxenyeni ezijiyile neziyinhlanganisela. Ukubumba nge-thermoforming kunikeza ukujikeleza okusheshayo kwezinto ezibumbekile ezilula. Ukuqonda lezi zivumelwano kusiza ukuthuthukisa ukusebenza komkhiqizo nekhwalithi yomkhiqizo.

Uhlolo oluhlelekile luhlanganisa ukuhlaziya izici eziningana ezibalulekile. Umthamo wokukhiqiza uthinta ukwenzeka kwenqubo; imithamo ephezulu ngokuvamile ithanda ukubunjwa komjovo ukuze kukhokhelwe izindleko. Izidingo ze-tolerance kanye nokuqedwa kobuso ziqondisa izinketho ezinhlelweni ezinokulawula okuqinile njengokubunjwa komjovo. Izimo eziyinkimbinkimbi zivame ukudinga ukubunjwa komjovo noma ukucindezela. Imikhawulo yebhajethi yamathuluzi ingase iqhubekele ekubunjweni kwe-thermoforming noma i-blow molding. Ukuhambisana kwezinto kubalulekile—ukufanisa izinhlobo ze-resin njenge-PP, i-HDPE, noma ama-thermosets nenqubo efanele kuqinisekisa ukusebenza komkhiqizo. Ukusebenzisa lolu hlelo kuvumela abakhiqizi ukuthi benze izinqumo ezinolwazi, ezihlelekile.

石家庄嘉源塑料制品有限公司 (Hebei Jiayuan Plastic Products Co., Ltd.) isekela imboni yokubumba ipulasitiki ngokuletha izingxenye zepulasitiki eziklanyelwe ukuhlangabezana nezidingo zokukhiqiza. Le nkampani igcizelela ikhwalithi yokuncibilika nobuchwepheshe bokugada ngesikhathi sangempela, kuthuthukisa ukungaguquguquki kwenqubo kanye nekhwalithi yezingxenye.

Ulwazi olwengeziwe lutholakala kuwoMayelana Nathi ikhasi.

Ukukhetha inqubo efanele yokubumba ipulasitiki kubalulekile empumelelweni yokukhiqiza, kuthinta ngqo izindleko, ikhwalithi, nokusebenza kahle. Ukuqonda ngokujulile amandla nemikhawulo yenqubo ngayinye yokubumba, ehambisana nezidingo zokukhiqiza, kuvumela abakhiqizi ukuthi balolonge utshalomali kumathuluzi, izikhathi zokujikeleza, nokusebenza komkhiqizo. Ukuhlola okuqhubekayo nokuthuthukiswa kwenqubo, okusizwa abalingani abanjengo-石家庄嘉源塑料制品有限公司, kunika amandla izinkampani ukuthi zigcine izinzuzo zokuncintisana embonini yepulasitiki eguqukayo.

Ukubumba ngomjovo kulungile ngenxa yokunemba kwayo okuphezulu nezikhathi ezisheshayo zokujikeleza ezihambisa izindleko zamathuluzi ezintweni eziningi.

Ukubumba nge-thermoforming nokubumba ngomoya kuvame ukudinga utshalomali oluphansi lokuqala lwamathuluzi uma kuqhathaniswa nokubumba ngomjovo.

Ukubumba ngomjovo kusekela ukulawula okukhulu kobukhulu phakathi kwezinqubo ezivamile zokubumba ipulasitiki.
