Ibikorwa Byibanze bya Plastike

Mbere yuburyo bukuru bwo gusohora, ibiryo bya polymeric byabitswe bivangwa ninyongeramusaruro zitandukanye nka stabilisateur (kubushyuhe, okiside itajegajega, ituze rya UV, nibindi), ibara ryibara ryibara ryumuriro, kuzimya umuriro, kuzuza, amavuta, imbaraga, nibindi kugirango bitezimbere ubuziranenge bwibicuruzwa nibikorwa.Kuvanga polymer ninyongeramusaruro nabyo bifasha kugera kumurongo wumutungo wihariye.

 
Kuri sisitemu zimwe na zimwe, ubundi buryo bwo kumisha kugirango hirindwe kwangirika kwa polymer bitewe nubushuhe busanzwe bukoreshwa.Ku rundi ruhande, kubidakenera gukama mbere yo gukoreshwa, birashobora gukomeza gukama cyane cyane iyo byabitswe mu byumba bikonje hanyuma bigahita bishyirwa ahantu hashyushye bityo bigatangira kwangirika hejuru y’ibikoresho.
Nyuma ya polymer ninyongeramusaruro zimaze kuvangwa no gukama, imvange ni gravit igaburirwa muri hopper yo kugaburira no kunyura mu muhogo wa extruder.
Ikibazo kimwe gikunze kugaragara mugukoresha ibikoresho bikomeye nkifu ya polymer nigenda ryayo.Rimwe na rimwe, ibiraro bifatika imbere muri hopper birashobora kubaho.Niyo mpamvu, ingamba zidasanzwe nko gutera inshinge za azote cyangwa gazi iyo ari yo yose ya inert irashobora gukoreshwa kugirango ihungabanye polymer iyo ari yo yose yubatswe hejuru y’ibiryo bityo bigatuma ibintu bigenda neza.

Ibikoresho bitemba mumwanya wa buri mwaka hagati ya screw na barriel.Ibikoresho nabyo bigengwa numuyoboro wa screw.Mugihe umugozi uzunguruka, polymer itangwa imbere, kandi imbaraga zo guterana zigikora.
Ibigega bisanzwe bishyuha hamwe nubushyuhe bwiyongera buhoro buhoro.Mugihe uruvange rwa polymer rugenda ruva mukarere kagaburira rugera kuri metero, imbaraga zo guterana no gushyushya ingunguru zitera ibikoresho kuba plastike, kuvangwa kimwe, no gukomeretsa hamwe.
Ubwanyuma, nkuko gushonga byegereje iherezo rya extruder, inyura mbere binyuze muri paki ya ecran.Ipaki ya ecran ikoreshwa mugushungura ibikoresho byose byamahanga mumazi ya thermoplastique.Irinda kandi umwobo wa plaque idapfa.Gushonga noneho birukanwa mu rupfu kugirango babone imiterere y'urupfu.Irahita ikonjeshwa kandi ikururwa na extruder kumuvuduko uhoraho.
Ibindi bikorwa nko kuvura flame, gucapa, gukata, annealing, deodorisation, nibindi birashobora gukorwa nyuma yo gukonja.Extrudate noneho izakorerwa igenzura hanyuma ikomeze gupakira no kohereza niba ibicuruzwa byose byujujwe.
