Akamaro k'imiyoboro ya PVC
1. Uburyo bwo gutwara: Ibikoresho bya UPVC bifite uburemere bwihariye bungana na kimwe cya cumi cy'icyuma gishongeshejwe, bigatuma bihendutse kubitumiza no kubishyiraho.
2. UPVC ifite ubudahangarwa bwinshi bwa aside na alkali, usibye aside zikomeye na alkali zegereye aho amazi anyura cyangwa ogisijeni ikomeye ku rugero ntarengwa.
3. Ntizitwara umuriro: Kubera ko ibikoresho bya UPVC bidatwara umuriro kandi ntibiba byangiritse iyo bihuye n'umuriro cyangwa amashanyarazi, nta bundi buryo bwo gutunganya bukenewe.
4. Nta mpungenge zihari ku bijyanye no kurinda inkongi kuko zidashobora gutwika cyangwa ngo zitere umuriro.
5. Gushyiramo biroroshye kandi bihendutse bitewe n'uko hakoreshejwe kole ya PVC, byagaragaye ko yizewe kandi ifite umutekano, yoroshye gukoresha, kandi ihendutse. Gukata no guhuza nabyo biroroshye cyane.
6. Ubudahangarwa bwiza bw'ikirere no kurwanya ingese ya bagiteri n'ibihumyo bituma ikintu cyose kiramba.
7. Ubudahangarwa buke n'umuvuduko mwinshi w'amazi: urukuta rw'imbere rworoshye rugabanya gutakaza amazi, rukarinda imyanda gufata ku rukuta rw'umuyoboro woroshye, kandi bigatuma kubungabunga byoroha kandi bihendutse.

Plasitike si PVC.
PVC ni pulasitiki ikoreshwa mu bintu byinshi ishobora gukoreshwa mu bintu bitandukanye, harimo ibikoresho bisanzwe n'ahantu ho kubaka.
Mu bihe byashize, PVC yari pulasitiki yakoreshwaga cyane ku isi kandi yari ifite akamaro gatandukanye. Ikoreshwa cyane mu bikoresho by'ubwubatsi, mu nganda, mu bikoresho bya buri munsi, mu ruhu rwo hasi, mu matafari yo hasi, mu ruhu rw'ubukorikori, mu miyoboro, mu nsinga, mu mafirime yo gupfunyika, mu macupa, mu migozi, mu bikoresho byo gufunga, no mu bindi bintu.

Ikigo Mpuzamahanga cy’Umuryango w’Abibumbye gishinzwe Ubushakashatsi ku Kanseri cyabanje gukora urutonde rw’ibintu bitera kanseri ku ya 27 Ukwakira 2017, kandi polyvinyl chloride yari imwe mu moko atatu y’ibintu bitera kanseri kuri urwo rutonde.
Polymeri idafite imiterere ya kristu, polyvinyl chloride ni polymer isimbuza atome imwe ya chlorine atome imwe ya hydrogen muri polyethylene. Iyi nyandiko itunganyijwe ku buryo bukurikira: n [-CH2-CHCl] Inyinshi muri monomeri za VCM zihujwe mu buryo buhuza umutwe n’umurizo kugira ngo zikore polymeri y’umurongo uzwi nka PVC. Atome zose za karuboni zihuzwa hamwe n’imigozi kandi zihuzwa mu buryo buziguye. Buri atome ya karuboni ifite sp3 hybrid.

Uruhererekane rwa molekile rwa PVC rufite imiterere migufi ya syndiotactic. Ubushyuhe bwa syndiotactic buzamuka uko ubushyuhe bwa polymerization bugabanuka. Hariho imiterere idahamye irimo imiterere y'umutwe umwe, uruhererekane rw'amashami, imigozi ibiri, allyl chloride, na tertiary chlorine mu miterere ya polyvinyl chloride macromolecular, ibyo bigatera ingorane nko kudahinduka k'ubushyuhe no kudasaza. Inenge nk'izo zishobora gukosorwa nyuma yo gusa n'aho zifatanye.

Uburyo bwo guhuza PVC:
1. Kole yihariye ikoreshwa mu guhuza imiyoboro ya PVC; kole igomba kunyeganyezwa mbere yo kuyikoresha.
2. Igice cy'isoko n'umuyoboro wa PVC bigomba gusukurwa. Uko umwanya uri hagati y'isoko ari muto, niko ubuso bw'ingingo bugomba kuba bworoshye. Hanyuma, oza kole kuri buri soko kandi ushyireho kole kabiri inyuma ya buri soko. Amasegonda 40 nyuma yo kumisha, shyiramo. Shyira kole kure hanyuma wite ku niba igihe cyo kumisha kigomba kongerwa cyangwa kikagabanuka bitewe n'ikirere.
3. Umuyoboro ugomba kuzura nyuma y'amasaha 24 nyuma yo kuwuhuza wumye, umuyoboro ugomba gushyirwa mu mwobo, kandi kunyagirwa birabujijwe cyane. Mu gihe wongera kuzuza, shyiramo uduce duto, wuzuze umucanga mu gace gakikije umuyoboro, kandi wuzuze cyane.
4. Kugira ngo uhuze umuyoboro wa PVC n'umuyoboro w'icyuma, sukura aho umuyoboro w'icyuma uhurira, uwushyushye kugira ngo woroshye umuyoboro wa PVC (utawutwitse), hanyuma ushyire umuyoboro wa PVC mu muyoboro w'icyuma kugira ngo ukonje. Ibisubizo bizaba byiza kurushaho niba imigozi ikoze mu muyoboro w'icyuma ishyizwemo.
imiyoboro ya PVCishobora guhuzwa mu buryo bumwe muri bune:
1. Iyo umuyoboro wangiritse cyane, woseumuyoborobigomba gusimburwa. Hashobora gukoreshwa icyuma gihuza imiyoboro ibiri kugira ngo ibi bikorwe.
2. Uburyo bwo gushonga bushobora gukoreshwa mu guhagarika kole y’ibinyabutabire. Muri iki gihe, amazi y’umuyoboro mukuru arasohoka, bigatuma umuvuduko w’umuyoboro uba mubi mbere yuko kole ishyirwa mu mwobo uri aho amazi yamenetse. Kole izakururwa mu myenge bitewe n’umuvuduko w’umuyoboro, igahagarika amazi yamenetse.
3. Intego nyamukuru yo gusana imigozi ni ukuva kw'agasanduku binyuze mu tuyobo duto. Umuyoboro umwe wa caliber ubu watoranijwe kugira ngo ucibwe mu buryo burambuye kandi ufite uburebure buri hagati ya pikseli 15 na 500. Ubuso bw'imbere bw'agasanduku n'ubuso bw'inyuma bw'umuyoboro wasanwe bihujwe ku ngingo hakurikijwe uburyo bwakoreshejwe. Nyuma yo gukoresha kole, ubuso burakonja, hanyuma bugahambirwa neza ku isoko ry'aho amazi yavuye.
4. Kugira ngo ukore umuti wa resin ukoresheje epoxy resin curing agent, koresha uburyo bwa fibre y'ikirahure. Iboherwa ku buso bw'umuyoboro cyangwa aho amazi ahurira nyuma yo kwinjizwa mu muti wa resin ukoresheje igitambaro cya fibre y'ikirahure, hanyuma nyuma yo gushonga, iba FRP.
