PVC

Ahanini, ibicuruzwa bya PVC bikozwe mu ifu ya PVC mbisi hakoreshejwe ubushyuhe nigitutu.Inzira ebyiri zingenzi zikoreshwa mugukora ni ugukuramo imiyoboro no guterwa inshinge.

Gutunganya PVC igezweho ikubiyemo uburyo bwa siyansi bwateye imbere busaba kugenzura neza ibihinduka.Ibikoresho bya polymer nifu yubusa itemba, bisaba kongeramo stabilisateur hamwe nibikoresho bifasha gutunganya.Gutegura no kuvanga ni ibyiciro byingenzi byimikorere kandi bisobanutse neza kubikwa kubikoresho fatizo byinjira, guteka no kuvanga.Kugaburira imashini zisohora cyangwa kubumba zishobora kuba zitaziguye, muburyo bwa "kuvanga byumye", cyangwa kubanza gutunganyirizwa muri granular "compound".

Gukabya

Polimeri ninyongeramusaruro (1) bipimwa neza (2) kandi bigatunganywa binyuze mumuvuduko mwinshi uvanze (3) kugirango uhuze ibikoresho bibisi bivanze kimwe bivanze byumye.Ubushyuhe bwo kuvanga hafi 120 ° C bugerwaho nubushyuhe bwo guterana.Mubyiciro bitandukanye byo kuvanga, inyongeramusaruro zirashonga kandi zigenda zambara buhoro buhoro PVC polymer granules.Nyuma yo kugera ku bushyuhe bukenewe, ikivunga gihita gisohoka mu cyumba gikonjesha kigabanya vuba ubushyuhe bugera kuri 50 ° C, bityo bigatuma imvange igezwa mu bubiko hagati (4) aho n’ubushyuhe n'ubucucike bigerwaho.

Umutima wibikorwa, extruder (5), ifite igenzurwa nubushyuhe, ingunguru ya zone aho izunguruka neza "screw".Ibikoresho bya kijyambere bigezweho ni ibikoresho bigoye, byateguwe neza hamwe nindege zitandukanye kugirango ugenzure compression nogosha, byakozwe mubikoresho, mugihe cyose cyibikorwa.Impanga ya konte-rotate ya screw ikoreshwa nabakora inganda zose zitanga uburyo bunoze bwo gutunganya.

Amashanyarazi ya PVC apimirwa muri barrale hamwe na screw, hanyuma bigahindura imvange yumye muburyo bukenewe "gushonga", hamwe nubushyuhe, igitutu nogosha.Mugihe cyanyuze kumurongo, PVC inyura muri zone nyinshi zikanda, homogenise kandi zigatemba imigezi yashonga.Agace ka nyuma kongerera umuvuduko wo gukuramo gushonga mumutwe no gupfa gushiraho (6) bikozwe ukurikije ubunini bwumuyoboro usabwa nibiranga imigezi irashonga.Umuyoboro umaze kuva muri extrait upfuye, bingana no kunyura mu ntoki zingana na vacuum yo hanze.Ibi birahagije kugirango ukomere igice cyinyuma cya PVC kandi ufate diameter ya pipe mugihe cyo gukonjesha bwa nyuma mubyumba bikonjesha amazi (8).

Umuyoboro ukururwa binyuze mubikorwa byo gukonjesha no gukonjesha na puller cyangwa gutwara (9) ku muvuduko uhoraho.Kugenzura umuvuduko ningirakamaro cyane mugihe ibi bikoresho bikoreshejwe kuko umuvuduko umuyoboro ukururwa bizagira ingaruka kurukuta rwibicuruzwa byarangiye.Kubijyanye na reberi impeta ihujwe n'umuyoboro ukururwa ugenda gahoro mugihe gikwiye kugirango umubyimba ugabanuke mu gice cya sock.

Mucapyi kumurongo (10) iranga imiyoboro mugihe gisanzwe, hamwe nibiranga ukurikije ingano, icyiciro, ubwoko, itariki, nimero isanzwe, numero ya extruder.Gukata byikora byikora (11) bikata umuyoboro muburebure busabwa.

Imashini ivuza ikora sock kumpera ya buri burebure bwa pipe (12).Hariho uburyo bubiri rusange bwa sock.Kuri reberi-impeta ihuriweho n'umuyoboro, urusenda rushobora gukoreshwa, mugihe urusenda rusanzwe rukoreshwa muguhuza socket.Umuyoboro w'impeta usaba icyuma kuri spigot, ikorerwa haba kuri sitasiyo yabonetse cyangwa mu nzogera.
Ibicuruzwa byarangiye bibitswe ahantu hagenzurwa no gupima laboratoire no kwemerwa neza (13).Umusaruro wose urageragezwa kandi ugenzurwa ukurikije Australiya ikwiye kandi / cyangwa kubisobanuro byabaguzi.

Nyuma yo kugenzura no kwemerwa, umuyoboro urabikwa kugirango utegereze koherezwa bwa nyuma (14).

Ku miyoboro ya PVC (PVC-O) yerekanwe, inzira yo kuyikuramo ikurikirwa niyindi nzira yo kwaguka ibaho mugihe cyasobanuwe neza kandi kigenzurwa neza nubushyuhe nigitutu.Ni mugihe cyo kwaguka niho icyerekezo cya molekulari, gitanga imbaraga nyinshi zisanzwe za PVC-O, kibaho.

Gutera inshinge

Ibikoresho bya PVC bikozwe nuburyo bwo gutera inshinge nyinshi.Bitandukanye no gukomeza gusohora, kubumba ni inzira isubirwamo, aho "ishoti" ryibintu bigezwa kubibumbano muri buri cyiciro.

Ibikoresho bya PVC, haba muburyo bwa porojeri yumye cyangwa ifumbire mvaruganda, ni uburemere bwagaburiwe kuva hopper iri hejuru yikigo cyatewe inshinge, mukibari kibamo imigozi isubiranamo.

Barrale yishyuzwa plastike isabwa na screw izunguruka no kugeza ibikoresho imbere ya barriel.Umwanya wa screw washyizwe kumurongo "warashwe".Muri iki gikorwa, igitutu nubushyuhe “plastike” ibikoresho, ubu bishonga, bitegereje gutera inshinge.

Ibi byose bibaho mugihe cyo gukonjesha kurasa ryabanje.Nyuma yigihe giteganijwe ifumbire izakingurwa kandi ibishushanyo mbonera byuzuye bizasohoka bivuye mubibumbano.

Ifumbire noneho irafunga hanyuma plastiki yashongeshejwe imbere yikibari iterwa inshinge nyinshi numuyoboro ubu ukora nka plunger.Plastike yinjira mubibumbano kugirango ikore ibikurikira.

Nyuma yo gutera inshinge, kwishyuza biratangira mugihe ibishushanyo bibumbabumbwe bigenda bikurikirana.
