PVC SG-5 kumuyoboro,
PVC yo gukora imiyoboro, PVC SG-5 resin,

Sg-5 resin ifite urwego rwo hasi rwa polymerisation igomba guhitamo mubikorwa bikomeye.Urwego rwo hejuru rwa polymerisiyonike, imiterere yumubiri nubukanishi hamwe nubushyuhe
Ibyiza biranga ibyiza, ariko amazi mabi ya resin azana ingorane zimwe na zimwe mugutunganya, bityo viscosity ni rusange (1).7 ~ 1. 8) x 10-3 pa
• SG-5 resin ya S irakwiriye.Umuyoboro ukomeye muri rusange ukoresha icyerekezo cya stabilisateur, itunganijwe neza yubushyuhe, ubusanzwe bukoreshwa butatu bwibanze, ariko
Ubusanzwe ikoreshwa hamwe nisabune hamwe nisabune ya barium hamwe namavuta meza.Guhitamo no gukoresha amavuta ni ngombwa cyane mugutunganya imiyoboro ikomeye.
Amavuta yo kwisiga imbere hamwe n'amavuta yo hanze agomba kwitabwaho kugirango agabanye imbaraga za intermolecular, kugirango ibishishwa bya elegitoronike bigabanuke kugirango bibeho, kandi birinde gushonga
Komera ku cyuma gishyushye kugirango utange ubuso bwiza.Isabune yicyuma ikoreshwa muburyo bwo gusiga imbere, kandi ibishashara bifite aho bishonga bikoreshwa mumavuta yo hanze.Umwigisha wuzuza
Kugira ngo ukoreshe calcium karubone na barium (ifu ya barite), karubone ya calcium ituma imikorere yubuso bwumuyoboro iba nziza, barium irashobora kunoza imiterere, kuburyo umuyoboro woroshye gukora, bibiri
Igiciro kirashobora kugabanuka, ariko byinshi bizagira ingaruka kumikorere yumuyoboro, umuyoboro wumuvuduko numuyoboro urwanya ruswa byari byiza kutongera cyangwa kongeramo bike.

Imiyoboro ya PVC na CPVC ni iki?

Imiyoboro ya PVC

Yatejwe imbere mu myaka ya za 1930, imiyoboro ya PVC (polyvinyl chloride) yabaye ihame ry’imiyoboro ya komini n’inganda ku isi.Muri Amerika, bitatu bya kane by'amazu yose akoresha PVC.Kuva mu myaka ya za 1950, byahindutse gusimbuza imiyoboro y'icyuma

PVC ikorwa hifashishijwe bumwe muri butatu bwa polymerisime: guhagarika polymerisation, emulion polymerisation, cyangwa polymerisation nyinshi.Ubwinshi bwa PVC bukozwe hakoreshejwe guhagarika polymerisation.

Ni ngombwa kumenya ko imiyoboro ya PVC ije muburyo bubiri: bukomeye kandi budafite amashanyarazi.Imiterere itajenjetse ishobora kuba iyambere mubitekerezo - tekereza amazi meza, amazi, imyanda, nubuhinzi.Ifishi idashyizwemo imashini iroroshye, nibyiza gukoreshwa mubisabwa nko kuvura ubuvuzi no kubika insinga z'amashanyarazi.

Ibyiza bimwe byumuyoboro wa PVC harimo imbaraga zayo, kuramba cyane, kugiciro gito, kwishyiriraho byoroshye, no kurwanya ingese no kwangirika.

Imiyoboro ya CPVC

CPVC mubyukuri ni PVC yashizwemo chlorine.Inzira ya chlorine ituma CPVC ihanganira ubushyuhe bwo hejuru - kugeza kuri 200 ° F - kandi igateza umuriro hamwe no kurwanya ruswa.Bitewe nubushyuhe bwo hejuru, inyubako nyinshi zubaka zisaba imiyoboro ya CPVC kumazi ashyushye, nubwo ishobora gukoreshwa mumazi meza ashyushye kandi akonje.Byongeye kandi, CPVC yinjijwe cyane mugukoresha sisitemu yo kumena umuriro.

Urutonde rwibyiza bya CPVC rwongeyeho.Kuri imwe, imiti yubushyuhe nubushyuhe bituma iramba bidasanzwe kandi ikanatanga igihe kirekire.

Bitewe nubushobozi bwayo bwo guhangana nubushyuhe bwo hejuru hamwe nubunini bwagutse bwubucuruzi ninganda, CPVC iza ku giciro kiri hejuru ya PVC.

Ni irihe tandukaniro riri hagati y'imiyoboro ya PVC na CPVC?

Itandukaniro nyamukuru hagati ya PVC na CPVC nubushobozi bwabo bwo guhangana nubushyuhe.Nkuko byavuzwe mbere, umuyoboro wa CPVC urashobora kwihanganira kugera kuri 200 ° F, mugihe umuyoboro wa PVC ushobora kwihanganira kugera kuri 140 ° F.Niba ugiye hejuru yubushyuhe, byombi bizatangira koroshya, bishobora gutera ingingo gucika intege kandi imiyoboro ikananirwa.Nkigisubizo, abapompa benshi bazagusaba gukoresha CPVC kumirongo y'amazi ashyushye na PVC kumirongo y'amazi akonje.

Nubwo PVC ifite ibyiza byinshi, CPVC ifite ihinduka ryinshi, kandi iraboneka mubunini bwumuringa wizina (NPS) nubunini bwumuringa (CTS).Ibinyuranye, PVC iraboneka gusa muri sisitemu ya NPS.Imiyoboro yombi iraboneka muri metero 10 na 20 z'uburebure.

Kubireba isura, imiyoboro ya PVC ni umweru cyangwa umukara wijimye wijimye, kandi imiyoboro ya CPVC mubisanzwe iba yera, yera yijimye, cyangwa umuhondo.Niba harigihe hari ikibazo, byombi bizaba bifite tekiniki yubuhanga byacapwe kuruhande.Kubera ko imiterere yimiti itandukanye hagati yibi byombi, sima ya solvent hamwe nibikoresho bihuza ntibigomba gukoreshwa muburyo bumwe.

Ni irihe sano riri hagati ya PVC na CPVC?

Iyo bigeze kubijyanye na tekiniki nu mubiri, byombi PVC na CPVC bifite urutonde rushimishije rwibyiza.Kuri imwe, imiterere yimiyoboro yombi ibemerera kurwanya ruswa no kwangirika bivuye mumiti.Icya kabiri, byombi bifite umutekano gukoresha n'amazi meza mugihe ANSI / NSF 61 byemejwe.Byombi biza muri gahunda ya 40 na Gahunda ya 80 yubugari, kandi biraboneka kumpera yanyuma no kumpera yinzogera.Byongeye kandi, Gahunda 40 PVS ije mu cyiciro cya 125.

Nka bonus yongeyeho kubikorwa byabo byoroshye byo kwishyiriraho, byombi birwanya ingaruka cyane kandi biramba, byemerera ubuzima bwimyaka mirongo itanu kugeza kuri mirongo irindwi.Kandi bitandukanye n'umuringa, igiciro cy'imiyoboro yombi ya PVC na CPVC ntabwo gishingiye ku gaciro k'isoko.

PVC resin irashobora gutunganyirizwa mubicuruzwa bitandukanye bya plastiki.Irashobora kugabanywamo ibicuruzwa byoroshye kandi bikomeye ukurikije uko ikoreshwa.Ikoreshwa cyane cyane mu gukora impapuro zibonerana, ibikoresho byo mu miyoboro, amakarita ya zahabu, ibikoresho byo guterwa amaraso, imiyoboro yoroshye kandi ikomeye, amasahani, inzugi n'amadirishya.Umwirondoro, firime, ibikoresho byo gukwirakwiza amashanyarazi, amakoti ya kabili, guterwa amaraso, nibindi

PVC isabwa iterwa nubwubatsi, ubuhinzi, gupakira hamwe nibicuruzwa byumurenge.Ku isoko ryimbere mu gihugu PVC resin ikoreshwa mugukora ibicuruzwa byoroshye kandi byoroshye PVC.Hafi ya 55% byimigabane yisoko ifitwe nigice cya PVC Imiyoboro & Fittings yonyine, ibindi bice birimo Film & Sheet, Cable Compound, Flexible hose, Inkweto, Umwirondoro, Flooring and Foam Board.Ku isoko ryimbere rya PVC, resin ikoreshwa cyane mugukora imiyoboro ya PVC.Hafi ya 55% yo gukoresha resin iri muri uyu murenge wonyine.Izindi nzego zirimo uruhu rwubukorikori, inkweto, amabati akomeye kandi yoroshye, amashanyarazi yubusitani, amadirishya ninzugi nibindi. PVC yo kugurisha imbere mu gihugu yagiye yiyongera ku gipimo cya 5% ku mwaka.
