Gukuramo plastike birakoreshwa cyane mubikorwa bya plastiki byubu kuko biroroshye kuboneka kandi byoroshye gukorana nabyo.Uburyo bwo gukuramo plastike burimo gushonga ibikoresho bya pulasitike, kubihatira gupfa kugirango bibe umwirondoro uhoraho, hanyuma ubikatire uburebure.Inzira ni ihitamo ryiza kubisabwa bisaba ibicuruzwa byanyuma hamwe no guhora kwambukiranya.Igiciro gito nigiciro kinini cyumusaruro bituma ihitamo gukora mubicuruzwa nkibikoresho, imiyoboro ya pulasitike, kwambura ikirere, insinga hamwe na kaseti.
Ibikoresho byo gukuramo plastike
Mbere yo gutangira inzira yo gukuramo plastike, imashini zikwiye nibikoresho bigomba kuboneka, cyane cyane imashini ya plastike.Iki gikoresho ni imashini yoroshye cyane yorohereza inzira yo gukuramo kuva itangiye kugeza irangiye.Ibice byingenzi bigize extruder ya plastike harimo hopper, barrel, drake na moteri ya moteri.
Ikintu cya kabiri cyingenzi ni ibikoresho bya thermoplastique bibisi bigenewe gusohora.Ibyinshi mubikorwa byo gusohora bishingiye kuri resin plastike (amasaro mato mato) kugirango yemererwe gupakira byoroshye no gushonga byihuse.Ibikoresho bya pulasitiki bisanzwe bikoreshwa mugikorwa cyo gukuramo harimo polystirene (HIPS), PVC, polyethylene, polypropilene, na ABS.
Ikintu cya nyuma gikenewe mugukuramo plastike ni ugupfa.Urupfu rukora nk'ibishushanyo bya plastiki - mu gusohora plastike, gupfa bituma habaho gutembera kwa plastiki yashonze.Gupfa mubisanzwe bigomba kuba byarakozwe kandi birashobora gusaba igihe cyo kuyobora mbere yo gutangira ibikorwa.
Inzira yihariye yo gukuramo plastike
Porogaramu nyinshi zirahamagarira uburyo bwihariye bwo gukuramo kugirango tubone ibisubizo bihagije cyangwa byihutishe umusaruro.Ibikorwa bisanzwe byo gukuramo birimo:
●Gukuramo firime:Ikoreshwa muguhimba ibicuruzwa bya firime ya pulasitike nkibiribwa hamwe n imifuka yo guhunika ibiryo Impfu muriki gikorwa zirimo igishushanyo kiboneye, cya silindrike gikurura plastiki yashongeshejwe hejuru uko ikora kandi ikonje.
●Gufatanya:Ibice byinshi bisohoka icyarimwe.Babiri cyangwa benshi basohora ibiryo bigaburira ubwoko butandukanye bwa plastike mumutwe umwe.
●Kurenza ikoti:Extrusion ikoreshwa mugutwikira ikintu muburyo bwa plastike ikingira.Umugozi wo hanze hamwe na jacketi ya kabili nibisanzwe bikoreshwa muburyo bukabije.
●Kubyimba:Bisa no gusohora gakondo, usibye gupfa harimo pin imbere cyangwa mandel kugirango byorohereze umusaruro wibikoresho bya pulasitike bidafite akamaro.
Inzira Yibanze yo Gukuramo Plastike
Igikorwa cyo gukuramo plastiki gitangirana no gushyira ibisigazwa mbisi muri hopper ya extruder.Niba resin ibuze inyongera zikenewe mubisabwa byihariye (nka UV inhibitor, anti-okiside, cyangwa amabara), noneho byongewe kuri hopper.Iyo ibinini bimaze gushyirwaho, mubisanzwe bigaburirwa imbaraga zinyuze mu muhogo wo kugaburira umuyonga hasi muri barri ya extruder.Muri barrale harimo umugozi muremure, uzunguruka ugaburira ibisigazwa imbere muri barrale ugana ku rupfu.
Mugihe ibisigazwa bigenda muri barriel, biterwa nubushyuhe bwo hejuru cyane kugeza butangiye gushonga.Ukurikije ubwoko bwa thermoplastique, ubushyuhe bwa barrale burashobora kuba hagati ya dogere 400 na 530 Fahrenheit.Abenshi muri extruder bafite barrale igenda yiyongera mubushyuhe kuva aho imizigo igarukira kugeza kumuyoboro wibiryo kugirango ushire buhoro buhoro kandi bigabanye amahirwe yo kwangirika kwa plastike.
Iyo plastiki yashongeshejwe igeze kumpera ya barrale, ihatirwa binyuze mumapaki ya ecran hanyuma igaburirwa mu muyoboro w'ibiryo biganisha ku rupfu.Mugaragaza, ushimangirwa nisahani yamenetse kubera umuvuduko mwinshi muri barriel, ikora kugirango ikureho umwanda ushobora kuba uri muri plastiki yashonze.Ubwinshi bwa ecran, umubare wa ecran, nibindi bintu birashobora gukoreshwa kugeza igihe gushonga bibaye biturutse kumubare ukwiye wumuvuduko winyuma.
Iyo umuyoboro ugaburira, icyuma gishongeshejwe kigaburirwa mu cyuho cyo gupfa, aho gikonje kandi kigakomera.Kwihutisha uburyo bwo gukonjesha, plastiki nshya yashizwemo yakira ubwogero bwamazi.Mugihe cyo gukuramo plastike, imizingo ikonjesha isimbuza ubwogero bwamazi.
