Banza wumve icyo PVC aricyo.Polyvinyl-Chloride izwi nka PVC.Biroroshye gutangiza ubucuruzi bwo gukora imiyoboro ya PVC murwego ruto kandi ruciriritse.Imiyoboro ya PVC ikoreshwa cyane mu mashanyarazi, kuhira no kubaka.PVC isimbuza ibikoresho byinshi nkibiti, impapuro nicyuma mubisabwa byinshi.Ikoreshwa cyane nk'umuyoboro w'amashanyarazi murugo no mugukoresha inganda.
Imiyoboro ya PVC ikoreshwa cyane mugutanga amazi kuko ifite ibiyiranga.Nibyoroshye kandi bifite igiciro gito.Imiyoboro ya PVC iroroshye kuyishyiraho kandi ntabwo yangirika.Umuyoboro wa PVC ufite imbaraga nyinshi zo kwihanganira umuvuduko mwinshi w'amazi.Imiyoboro ya PVC irwanya cyane imiti hafi ya yose kandi ifite ubushyuhe bwinshi nubushakashatsi bwamashanyarazi.
Icyifuzo cy'umuyoboro wa PVC kiriyongera mu Buhinde kuko ibikorwa remezo bigenda byiyongera.Imiyoboro ya PVC ikoreshwa cyane mubikorwa byubwubatsi nubuhinzi kandi ibyifuzo biriyongera mugihe cya vuba.Imiyoboro ya PVC ikoreshwa cyane mubikorwa bitandukanye nko gutanga amazi, kuhira imyaka, kuvoma neza imiyoboro myiza ndetse no kuvoma ubutaka.
Imiyoboro ihanamye kandi isukuye ikoreshwa cyane cyane mu kuvoma amazi ku butaka aho bikenewe.Icyifuzo kiragenda cyiyongera mu cyaro cyo gutanga amazi, kuhira, hamwe n’iterambere mu nganda z’ubwubatsi ndetse no kwagura umuyoboro w’amashanyarazi mu cyaro.Kurenga 60% byumuyoboro wa PVC uri muri mm 110 z'uburebure.
Mbere yo gukora mbere, ugomba kwiyandikisha muri ROC.Noneho shakira uruhushya rwubucuruzi muri Komine.Saba kandi uruhushya rwuruganda nkuko amategeko ya leta abiteganya.Saba Udyog Aadhar MSME kwiyandikisha kumurongo no kwiyandikisha kuri TVA.Shaka 'Nta cyemezo cyemewe' mu kigo cya leta gishinzwe kurwanya umwanda.Shaka icyemezo cya BIS cyo kugenzura ubuziranenge.Fungura konti ya banki iriho muri banki yigihugu.Kurinda ikirango cyawe ukoresheje Kwiyandikisha.Kandi usabe kandi icyemezo cya ISO.
Ibikoresho fatizo nka PVC resin, DOP, Stabilisers, Gutunganya acide, Amavuta, Amabara hamwe nuwuzuza birakenewe mugukora imiyoboro ya PVC.Amazi n'amashanyarazi ni ngombwa.
Kubikorwa bya PVC, imiyoboro ya PVC itavanze ntabwo ikwiye gutunganywa.Kugirango inzira igende neza kandi itajegajega, ibyongeweho birasabwa kuvanga na resin ya PVC.Hariho inyongeramusaruro zikoreshwa mugukora imiyoboro ya PVC ni: DOP, DIOP, DBP, DOA, DEP.
Plastiseri - hari plastike isanzwe ikoreshwa ni DOP, DIOP, DOA, DEP, Reoplast, Paraplex nibindi.
Amavuta - Buty-Stearate, Glycerol Moni-Stearate, Epoxidised Monoester ya acide oleic, aside stearic nibindi.
Mbere yuko inzira itangira PVC, resin yongewemo na plasitike, stabilisateur, amavuta yo kwisiga hamwe nuwuzuza kugirango tunoze inzira kandi ihamye yibicuruzwa.Ibigize hamwe na resin bivanze nuruvange rwihuta.
Ibisigarira bigaburirwa ibyuma bisohora kabiri kandi bipfa gushiramo byashyizwe kuri diameter isabwa.Ibikurikira ibice bya PVC byanyujijwe mucyumba gishyushye hanyuma bigashonga munsi yo kwikuramo imigozi nubushyuhe bwa barriel.Ikimenyetso gikozwe mugihe cyo gukuramo.
Imiyoboro iva muri extruder ikonje mugikorwa kinini.Hariho ubwoko bubiri bwubunini bukoreshwa aribwo Kuringaniza Umuvuduko na Vacuum Sizing.
Nyuma yo gupima hariho gukurura.Igice cyo gukurura imiyoboro irakenewe kugirango uhore ukurura imiyoboro isohorwa na extruder.
Gukata ninzira yanyuma.Hariho ubwoko bubiri bwo gukata bukoreshwa kumiyoboro ya PVC.Igitabo na Automatic.Mugusoza imiyoboro igeragezwa kubimenyetso bya ISI kandi yiteguye kohereza.
Mubuhinde ubwoko bwinshi bwimashini zikora imiyoboro ya PVC zirakorwa ariko muribi Itsinda rya Devikrupa Rikora Imashini nziza.
