PVC YASIGAYE KUBONA
PVC YASUBIZE KUBONA,
Umuyoboro wa PVC, PVC Umugozi wibikoresho, PVC Kumashanyarazi, PVC isubiramo insinga,
PVC kubera ko ifite imikorere myiza yumubiri, imiti, amashanyarazi, flame retardant, mumwaka wa 1930 na 40, abanyamahanga batangiye gukoresha PVC yoroshye nkibikoresho byo kubika insinga, guteza imbere no gukoresha ibikoresho bya kabili bya PVC mugihugu cyacu byatangiye muri 1950.Hamwe nogutezimbere ubushobozi bwibikorwa bya PVC resin, plasitike ninyongeramusaruro yinganda no kuzamura no gukoresha ubwoko bushya, inganda zikoresha insinga zifite ubuziranenge.
Mu kinyejana cya 21, hamwe no kurushaho gukangurira abantu kwita ku bidukikije no kwita ku buzima bwabo, ibibazo by’ibidukikije byibanze ku muryango w’abantu.Ibihugu byinshi, uturere n’amashyirahamwe byashyizeho amategeko n'amabwiriza akomeye kugira ngo agabanye ikoreshwa ry’ibintu byangiza, cyane cyane amabwiriza ya RolS na REACH.Gushakisha uburyo bushya nuburyo bushya, kunoza igipimo cy’imikoreshereze y’umutungo, guhuza n'ibisabwa n'amategeko agenga kurengera ibidukikije, ibikoresho byo kurengera ibidukikije bya PVC byagaragaye muri iki gihe, kandi bihita bihinduka imwe mu nsanganyamatsiko z’iterambere ry’ibikoresho bya PVC bigezweho. .
Kwiyongera kwinshi no kwagura isoko ryinsinga ninsinga (byitwa umugozi), hamwe nubushakashatsi bwimbitse bwibintu bitandukanye byongeweho (nk'inyongeramusaruro ya flame retardant, suppressor umwotsi), biteza imbere no gushyira mubikorwa bishya ikoranabuhanga, ibikoresho bishya nibicuruzwa bishya byibikoresho bya PVC.Mubintu byinshi kama kama (nka plastiki, reberi) bikoreshwa muruganda rwa kabili, ubwinshi bwibikoresho bya kabili PVC nibikoresho byambere kama mugihugu cyacu.
Thermoplastique high-molecular polymer yakozwe na polymerisation yo guhagarika vinyl chloride monomer.Inzira ya molekile: - (CH2 - CHCl) n - (N: urwego rwa polymerisation, N = 590 ~ 1500).Nibikoresho fatizo bikoreshwa cyane mugukora plastike.Ifite imiti ihamye, irwanya ruswa kandi irwanya amazi.

Porogaramu
Polyvinyl chloride resin ifite ibintu byinshi bisabwa, nk'imbere mu modoka, ibikoresho byo gushariza umuryango, agasanduku k'urumuri rwamamaza, inkweto z'inkweto, imiyoboro ya PVC n'ibikoresho, imyirondoro ya PVC na hose, urupapuro rwa PVC n'isahani, firime izunguruka, ibikinisho byaka, ibicuruzwa byo hanze, Umugozi wa PVC na kabili, PVC uruhu rwubukorikori, ibiti na plastiki hasi, ikibaho gikonjesha, nibindi.
