Ikibaho cya PVC gikoreshwa mubyiciro byose, cyane cyane mubikoresho byubaka.Waba uzi ibibazo bishobora kuvuka mugihe cyo gukora imbaho za PVC?Hasi, umwanditsi azakubwira ibyabo.
Ukurikije ibipimo byinshi byo kubira ifuro, birashobora kugabanywa kubira ifuro ryinshi no kubira ifuro rito.Ukurikije ubworoherane nubukomere bwimiterere ya furo, irashobora kugabanywamo ibice bikomeye, igice-gikomeye kandi cyoroshye.Ukurikije imiterere y'utugari, irashobora kugabanywamo plastike ifunze-ifunze na plastike ifunguye.Impapuro zisanzwe za PVC zirakomeye zifunze-selile ntoya-ifuro.Amabati ya PVC afite ibyiza byo kurwanya ruswa, kurwanya ikirere, kutagira umuriro, nibindi, kandi bikoreshwa cyane mubice byinshi, birimo ibyapa byerekana, ibimenyetso, ibyapa byamamaza, ibice, imbaho zubaka, ibikoresho byo mu nzu, nibindi. Kuganisha kuri selile nini mumpapuro zifuro nibice birebire.Inzira itaziguye yo kumenya niba imbaraga zo gushonga zidahagije ni ukujya inyuma yizingo eshatu hanyuma ugakanda isahani ipfunyitse kuri roller yo hagati n'intoki zawe.Niba imbaraga zo gushonga ari nziza, urashobora kumva elastique mugihe ukanze.Niba bigoye kumera nyuma yo gukanda, imbaraga zo gushonga ni nke.Kuberako imiterere ya screw nuburyo bwo gukonjesha bitandukanye cyane, biragoye kumenya niba ubushyuhe bwumvikana.Muri rusange, mubisobanuro byemewe bya extruder, ubushyuhe muri zone 3-5 bugomba kuba buke bushoboka.Kugirango ubone ibicuruzwa byinshi bibyibushye mumpapuro, birakenewe kandi ko ibikoresho bya PVC bifite imbaraga zo gushonga.Kubwibyo, ubuziranenge bwumubyimba ni ngombwa cyane.Kurugero, usibye ibikorwa byibanze byimfashanyo-rusange yo gutunganya, kugenzura ifuro rifite kandi uburemere bwa molekile hamwe nimbaraga zo gushonga, zishobora kuzamura cyane imbaraga zo gushonga zivanze na PVC kandi zikarinda ibibyimba no guturika., bivamo imiterere yimikorere ya selile hamwe nubucucike bwibicuruzwa biri hasi, mugihe nanone bizamura ubuso bwibicuruzwa.Birumvikana ko igipimo cyumuhondo wumuhondo hamwe numukozi wera wifuro nacyo kigomba guhuzwa.
Kubireba imbaho, niba ituze ridahagije, bizagira ingaruka kubibaho byose no hejuru yikibaho guhinduka umuhondo, kandi ikibaho cya furo kizaba cyoroshye.Igisubizo nukugabanya ubushyuhe bwo gutunganya.Niba nta terambere rihari, urashobora guhindura formula hanyuma ukongera muburyo bukwiye ingano ya stabilisateur na lubricant.Stabilisateur ni uburyo bwo gusiga amavuta bushingiye kumavuta yatumijwe hanze kugirango yongere ibintu neza.Ibikoresho birwanya ubushyuhe bifite amazi meza., kurwanya ubushyuhe bwiza;guhangana nikirere gikomeye, gutatana neza, gukomera no gushonga;gutekana kwiza, gutembera neza, gutembera kwagutse, gukoreshwa gukomeye hamwe no gusiga imbere no hanze.Amavuta afite ububobere buke, ibintu byihariye bidasanzwe, amavuta meza no gutatanya, kandi akoreshwa cyane mugutunganya plastike nizindi nganda.Ifite amavuta meza yo hanze no hanze;ifite ubwuzuzanye bwiza na polyethylene, chloride polyvinyl, polypropilene, nibindi. Byakoreshejwe nka dispersant, lubricant and brightening mugihe cyo kubumba imyirondoro ya PVC, imiyoboro, ibyuma bifata imiyoboro, PE na PP, kugirango bizamure urwego rwa plastike, bizamura ubukana kandi byoroshye ubuso bwibicuruzwa bya pulasitike, kandi birashobora guhinduka umwe umwe, byoroshye kubona ibibazo byihuse aho uri hose, ukemure ikibazo vuba bishoboka.Kubijyanye nuburinganire bwamavuta, kunyerera bidahagije bigaragarira muburyo ubushyuhe bwo muri zone 5 ya extruder bugoye kugenzura kandi gushyuha byoroshye, bikavamo ubushyuhe bwinshi murwego rwo guhuza, ibibazo nkibibyimba binini, ibituba, na umuhondo hagati yikibaho, kandi hejuru yikibaho ntabwo byoroshye;Kunyerera cyane bizatera imvura kuba ikomeye, izigaragaza mu miterere iri mu miterere no kugwa kwa kunyerera hanze hejuru yisahani.Bizagaragaza kandi nkibintu bimwe na bimwe bigenda bisubira inyuma bidasanzwe ku isahani.Kunyerera imbere bidahagije bivuze ko bigoye kugenzura ubunini bwikibaho, kibyibushye hagati kandi cyoroshye ku mpande zombi.Kunyerera cyane imbere bizaganisha ku bushyuhe bwo hejuru murwego rwo guhuza.
