IzimotoIsikhumba Sokwenziwa se-PVCUmbiko wemakethe uhlanganisa izitayela zakamuva zemakethe, ulwazi lomkhiqizo, kanye nesimo sokuncintisana kulo mkhakha. Umbiko uqokomisa abashayeli ababalulekile, izinselelo, kanye namathuba emakethe. Uphinde unikeze idatha ngemithelela yezomnotho emincane kanye nezibalo zabantu embonini ethile. Ngaphezu kwalokho, wethula ukuhlaziywa okuphelele kwabadlali ababalulekile, izingxenye, kanye nezinhlelo zokusebenza embonini yezimoto. Umbiko uhlanganisa usayizi wemakethe, ukusetshenziswa kokungenisa/ukuthumela ngaphandle, intengo, imali engenayo, kanye nesabelo semboni emakethe yomhlaba wonke yesikhumba sokwenziwa se-PVC.
Inqubo yokukhiqizaIsikhumba sokwenziwa se-PVCKuhlanganisa ukufudumeza izinto kabili. Kule nqubo, izinto eziyingozi njenge-formaldehyde ziyashintshashintsha kakhulu. Iphunga elisele liyancishiswa. Ngakho-ke, umkhiqizo unephunga eliphansi. Ngaphezu kwalokho, inqubo yokukhiqiza isikhumba sokwenziwa se-PVC izenzakalelayo kakhulu. Isibonelo, umugqa wokukhiqiza wekhalenda wamanje wenziwa eShayina. Lobu buchwepheshe bunezinzuzo eziningi.
Isikhumba Sokwenziwa se-PVC senziwe nge-resin ye-polyvinyl chloride (PVC) kanye nezinye izinto zokwenziwa kwepulasitiki. Izinto zokwakha zigqitshwe ngendwangu ukuze zifane nesikhumba. Izinto zokwakha zihlala isikhathi eside futhi zithambile kunesikhumba sangempela, okwenza zifanelekele ukusetshenziswa okuhlukahlukene. Kodwa-ke, intengo yesikhumba sokwenziwa se-PVC iphansi uma iqhathaniswa nesikhumba semvelo. Uma udinga isikhumba sokwenziwa sekhwalithi ephezulu sokuthenga kwakho okulandelayo kwesikhumba, cabanga ngokuthenga umkhiqizo we-PVC.
Inqubo yokukhiqiza ayilula njengokukhiqizaIsikhumba se-PVCkusukela ekuqaleni. Izinto eziyisisekelo zivame ukuba ukotini noma i-polyester. Zombili izindwangu zilukhuni futhi zinezimbobo, zidinga amasu okukhiqiza akhethekile. Abanye abakhiqizi besikhumba somgunyathi bakhiqiza izinto zabo eziyisisekelo, kodwa iningi labo lizithola ezindaweni zokukhiqiza ezivela eceleni. Ukuze uthole ukuhambisana okuphelele, cabanga ngokuqina nokuqina kwesikhumba se-PU. Lena impahla efanelekile yefenisha kanye nengaphakathi, futhi ingasetshenziswa ezimotweni nasemasofeni asezingeni eliphezulu.
Inqubo yokukhiqiza isikhumba sokwenziwa se-PVC iqala ngokufaka isiphetho se-polyurethane entweni eyisisekelo. Izinto eziyisisekelo ezivamile zifaka ukotini, i-polyester, i-nylon, kanye ne-rayon. Iphethini yokusanhlamvu kokwenziwa isetshenziswa kusetshenziswa i-roller. Umphumela wokugcina uba iphethini yokusanhlamvu kokwenziwa efanayo. Isikhumba se-PVC senziwe ngendlela efanayo nesikhumba se-PU. Isikhumba sokwenziwa se-PU senziwe ngenhlanganisela yezinto zokugcoba kanye nama-plasticizer.
Isikhumba se-PU nese-PVC yizinto zokwenziwa ezivame ukusetshenziswa efenisha nasezingutsheni. Zombili zenziwe ngendwangu engalukiwe futhi ziyamelana nokubuna. Ikhwalithi yesikhumba se-polyurethane izoncika ezintweni ezisetshenziswa enqubweni yokukhiqiza.
