PVC isubiramo imiyoboro yo kuhira
PVC isubiramo imiyoboro yo kuhira,
kuhira imiyoboro y'ibikoresho fatizo, pvc yo kuvomerera,
Umuyoboro wo kuhira PVC:
.Ubuso bwurukuta rwumuyoboro wa PVC uroroshye.Kurwanya amazi ni bito, kandi coefficient de coiffe ni 0.009 gusa, iri munsi yizindi miyoboro.Mugihe cyurugero rumwe, diameter ya pipe irashobora kugabanuka.Kurwanya umuvuduko wamazi, kurwanya umuvuduko winyuma hamwe ningaruka zo kurwanya imiyoboro ya PVC yo kuhira ni ndende cyane, ikwiranye nogukora imiyoboro mubihe bitandukanye.Nibihendutse kandi bikoreshwa cyane.
(2) Umuyoboro wo kuhira wa PVC urashobora gukurikiza neza uburyo bwo gukura kw ibihingwa kugirango ubone kuhira imyaka.Amazi yo kuhira arashobora gutoranywa ukurikije ubushuhe bwihariye bwibihingwa nubutaka.
.Ibi birashobora kugabanya imirimo yintoki.
.
. kuhira nindi mishinga minini nini nto.
Polyvinyl Chloride (PVC) ni umurongo wa termoplastique ugizwe na polymerisation ya vinyl chloride monomer.Bitewe no gutandukanya ibikoresho fatizo, hariho uburyo bubiri bwo guhuza vinyl chloride monomer calcium karbide hamwe na peteroli.Sinopec PVC ikoresha inzira ebyiri zo guhagarikwa, zikomoka mu Buyapani Shin-Etsu Chemical Company na American Oxy Vinyls Company.Ibicuruzwa bifite imiti myiza yo kurwanya ruswa, ibikoresho byiza byo gukwirakwiza amashanyarazi hamwe n’imiti ihamye.Hamwe na chlorine nyinshi, ibikoresho bifite umuriro mwiza wo kuzimya no kuzimya.PVC iroroshe gutunganywa mugusohora, gushushanya inshinge, kalendari, guhumeka, guhonyora, gushushanya no gushushanya ubushyuhe, nibindi.
