Izina RY'IGICURUZWA:Polyvinyl Chloride
Imiterere ya molekulari:C2H3Cl
CAS No.:9002-86-2
Imiterere ya molekulari y'ibicuruzwa:
Polyvinyl chloride, ikunze kuvugwa mu magambo ahinnye ya PVC, ni plastike ya gatatu ikorwa cyane, nyuma ya polyethylene na polypropilene.PVC ikoreshwa mubwubatsi kuko ikora neza kuruta ibikoresho gakondo nkumuringa, icyuma cyangwa ibiti mumiyoboro hamwe nibisabwa.Irashobora gukorwa yoroshye kandi yoroheje hiyongereyeho plasitike, ikoreshwa cyane ni phalite.Muri ubu buryo, bukoreshwa kandi mu myambaro no gupfunyika, kubika insinga z'amashanyarazi, ibicuruzwa bitwikwa hamwe na porogaramu nyinshi zisimbuza reberi.
Polyvinyl chloride nziza ni cyera, gikomeye.Ntishobora gushonga muri alcool, ariko irashonga gato muri tetrahydrofuran.
Peroxide- cyangwa thiadiazole-yakize CPE yerekana ubushyuhe bwiza bugera kuri 150 ° C kandi irwanya amavuta cyane kurusha elastomeri idafite inkingi nka reberi karemano cyangwa EPDFM.
Ibicuruzwa byubucuruzi byoroshye mugihe ibirimo chlorine ari 28-38%.Kurenza 45% bya chlorine, ibikoresho bisa na chloride polyvinyl.Ibiro byinshi-bifite uburemere bwa polyethylene bitanga chlorine polyethylene ifite ubukonje bwinshi nimbaraga zikomeye.
PVC igiciro gito ugereranije, ibinyabuzima na chimique irwanya kandi ikora byatumye ikoreshwa muburyo butandukanye.Ikoreshwa mu miyoboro yimyanda hamwe nindi miyoboro ikoreshwa aho igiciro cyangwa intege nke zo kwangirika bigabanya ikoreshwa ryicyuma.Hiyongereyeho impinduka zoguhindura hamwe na stabilisateur, byahindutse ibikoresho bizwi kumadirishya nimiryango.Mugushyiramo plasitike, irashobora guhinduka kuburyo bworoshye kugirango ikoreshwe muri cabling progaramu nka insulator.Byakoreshejwe mubindi bikorwa byinshi.
Imiyoboro
Hafi ica kabiri c'isi ya polyvinyl chloride resin ikorwa buri mwaka ikoreshwa mugukora imiyoboro ikoreshwa mumijyi ninganda.Ku isoko ryo gukwirakwiza amazi angana na 66% by isoko muri Amerika, naho mubikoresha imiyoboro y’isuku, bingana na 75%.Uburemere bwacyo bworoshye, igiciro gito, hamwe no kubungabunga bike bituma bikurura.Ariko, igomba gushyirwaho neza no kuryama kugirango irebe igihe kirekire kandi ikabije.Byongeye kandi, imiyoboro ya PVC irashobora guhuzwa hamwe ukoresheje sima zitandukanye zishishwa, cyangwa zashyizwemo ubushyuhe (inzira ya butt-fusion, bisa no guhuza umuyoboro wa HDPE), bigakora ingingo zihoraho zidashobora kumeneka.
Umugozi w'amashanyarazi
PVC isanzwe ikoreshwa nkugukingira insinga z'amashanyarazi;PVC ikoreshwa kubwiyi ntego igomba kuba plastike.
Polyvinyl chloride idafite amashanyarazi (uPVC) yo kubaka
uPVC, izwi kandi nka PVC itajenjetse, ikoreshwa cyane mu nganda zubaka nk'ibikoresho bidahagije, cyane cyane muri Irilande, Ubwongereza, ndetse no muri Amerika.Muri Amerika izwi nka vinyl, cyangwa vinyl side.Ibikoresho biza muburyo butandukanye bwamabara kandi birangira, harimo ifoto - ingaruka zinkwi zirangiza, kandi zikoreshwa mugusimbuza ibiti bisize irangi, cyane cyane kumadirishya yidirishya hamwe na silles mugihe ushyiramo glazing ebyiri mumazu mashya, cyangwa gusimbuza kera. Windows.Ibindi bikoreshwa birimo fascia, hamwe na side cyangwa ikirere.Ibi bikoresho byasimbuye hafi ya byose gukoresha ibyuma bikozwe mu kuvoma no kuvoma, bikoreshwa mu miyoboro y’imyanda, imiyoboro itwara amazi, imiyoboro n’amazi.uPVC ntabwo irimo phthalates, kubera ko ibyo byongewe gusa kuri PVC yoroheje, ntanubwo irimo BPA.uPVC izwiho kurwanya cyane imiti, urumuri rw'izuba, na okiside ituruka mu mazi.
Imyenda n'ibikoresho
PVC imaze gukoreshwa cyane mumyenda, kugirango ikore ibintu bisa nimpu cyangwa rimwe na rimwe gusa kubera ingaruka za PVC.Imyenda ya PVC irasanzwe muri Goth, Punk, imyenda yimyenda nubundi buryo bwo kwambara.PVC ihendutse kuruta reberi, uruhu, na latex ikoreshwa rero mu kwigana.
Ubuvuzi
Ibice bibiri byingenzi byifashishwa mubuvuzi bwa PVC byemewe nubuvuzi ni ibintu byoroshye kandi byogosha: ibikoresho bikoreshwa mumaraso namaraso yinkari cyangwa kubicuruzwa bya ostomy hamwe nigituba gikoreshwa mugutwara amaraso hamwe no gutanga amaraso, catheters, bypass yumutima, byashyizweho na hemodialysis nibindi. Mu Burayi gukoresha PVC kubikoresho byubuvuzi ni toni 85.000 buri mwaka.Hafi ya kimwe cya gatatu cyibikoresho byubuvuzi bishingiye kuri plastiki bikozwe muri PVC.
Igorofa
Igorofa ya PVC ihindagurika ntabwo ihendutse kandi ikoreshwa mumazu atandukanye arimo urugo, ibitaro, biro, amashuri, nibindi. Igishushanyo mbonera na 3D birashoboka kubera ibicapo bishobora gukorwa hanyuma bikarindwa nuburyo bwambaye neza.Hagati ya vinyl foam layer nayo itanga ibyiyumvo byiza kandi byiza.Ubuso bworoshye, bukomeye bwurwego rwo hejuru rwo hejuru birinda kwiyongera k'umwanda ubuza mikorobe kororoka ahantu hagomba kubikwa neza, nk'ibitaro n'amavuriro.
Ibindi Porogaramu
PVC yakoreshejwe kubicuruzwa byabaguzi bifite ingano ntoya ugereranije ninganda nubucuruzi byasobanuwe haruguru.Ubundi buryo bwambere bwisoko ryisoko ryabaguzi kwari ugukora vinyl records.Ingero ziheruka zirimo gufunga urukuta, pariki, ibibuga byo gukiniramo, ifuro nibindi bikinisho, hejuru yikamyo yabugenewe (tarpauline), amabati yo hejuru hamwe nubundi bwoko bwimbere.
Chemwin irashobora gutanga ibintu byinshi bya hydrocarbone hamwe nu muti wa chimique kubakiriya binganda.Mbere yibyo, nyamuneka soma amakuru y'ibanze akurikira yerekeye gukora ubucuruzi natwe:
1. Umutekano
Umutekano nicyo dushyira imbere.Usibye guha abakiriya amakuru ajyanye no gukoresha ibicuruzwa byacu neza kandi bitangiza ibidukikije, twiyemeje kandi ko umutekano w’abakozi n’aba rwiyemezamirimo wagabanuka kugeza ku gipimo cyiza kandi gishoboka.Kubwibyo, turasaba abakiriya kwemeza ko ibipimo bikwiye byo gupakurura no kubika ibicuruzwa byujujwe mbere yo gutanga (nyamuneka reba umugereka wa HSSE mumagambo rusange nuburyo bwo kugurisha hepfo).Impuguke zacu HSSE zirashobora gutanga ubuyobozi kuri aya mahame.
2. Uburyo bwo gutanga
Abakiriya barashobora gutumiza no gutanga ibicuruzwa biva muri chemwin, cyangwa barashobora kwakira ibicuruzwa biva muruganda rwacu rukora.Uburyo buboneka bwubwikorezi burimo amakamyo, gari ya moshi cyangwa ubwikorezi butandukanye (ibintu bitandukanye birakurikizwa).
Mugihe cyibisabwa abakiriya, turashobora kwerekana ibisabwa bya barge cyangwa tanker hanyuma tugashyiraho umutekano wihariye / gusuzuma ibipimo nibisabwa.
3. Umubare ntarengwa wateganijwe
Niba uguze ibicuruzwa kurubuga rwacu, umubare ntarengwa wateganijwe ni toni 30.
4. Kwishura
Uburyo busanzwe bwo kwishyura ni kugabanywa bitarenze iminsi 30 uhereye kuri fagitire.
5. Inyandiko zitangwa
Inyandiko zikurikira zitangwa na buri gutangwa:
· Umushinga w'itegeko, CMR Waybill cyangwa izindi nyandiko zijyanye no gutwara abantu
· Icyemezo cyo gusesengura cyangwa guhuza (niba bikenewe)
· Inyandiko zijyanye na HSSE zijyanye n'amabwiriza
· Inyandiko za gasutamo zijyanye n'amabwiriza (niba bikenewe)
