Gukuramo PVC, UPVC,
PVC Rigid (izwi kandi nkaUPVC) ni icya gatatu cyakozwe cyane na polymer.Kubijyanye no gusohora plastike, PVC niyo plastiki ikunze gukururwa cyane.Nibiciro bidahenze, bifite ibintu bisubirwamo kandi biratandukanye kubikoresha murugo no hanze.Ibi bitumaGukuramo PVCsa guhitamo gukunzwe kumurongo mugari wa porogaramu.uPVC isobanura PVC idashyizwe hamwe kandi ibikoresho birangwa nigihe kirekire n'imbaraga zayo.Nibindi bintu byahinduwe cyane na plastiki, ikomeye kubikorwa byinshi
Imiterere ya PVC
PVC ni polymer ikomeye ishobora kurushaho kunozwa ukoresheje impinduka.Gukuramo PVC gukomeye bifite imiti ikomeye.Ibi bivuze ko igituba gikomeye cya PVC gishobora gusudwa byoroshye, gufunga no guhuzwa ubwacyo - nibyiza kubihuza mumiyoboro.Kurwanya kwangirika gutuma imyirondoro ya PVC itagaragara, ibice hamwe na trim bikwiranye nibidukikije hanze.PVC ifite kandi ibikoresho byiza byo kubika amashanyarazi make.Ndashimira inyungu zayo nyinshi,Gukuramo PVCs na PVC ituje yakoreshejwe hamwe nitsinzi haba murugo no hanze.
Gukomera kwa PVC gukoreshwa
PVC ya Rigid ikoreshwa cyane mubwubatsi bw'amazi n'imyanda, konserwatori, imyanda, kwambara, kurinda urukuta n'inzugi hamwe n'amakadirishya kubera imiterere yubushyuhe bwiza kandi itajegajega.Mubisabwa byo gutwara uPVC ikoreshwa hanze kumubiri wibinyabiziga, caravani nubwato, ndetse no imbere mugukora ubwiza bushimishije, kuko iboneka mumabara menshi kandi irangije hejuru.Mu bucuruzi bwo kugurisha aho herekanwa, ububiko bwabitswe, impapuro zamatike hamwe nicyuma gifata ibyapa byose bikozwe muri PVC ikabije.
Ibiranga plastike ya termo, kuba idashobora gushonga mumazi, lisansi n'inzoga, kubyimba cyangwa gushonga muri ether, ketone, hydrocarbone ya alifatique ya chlorine, hamwe na hydrocarubone ya aromatique, kurwanya cyane ruswa, n'umutungo mwiza wa dielectric.
Gusaba
PVC Resin SG-3 Gusaba kuri:
1. Umwirondoro wa PVC
Umwirondoro ni murwego rwo gukoresha PVC mugihugu cyigihugu, hafi 25% yikoreshwa rya PVC yose, cyane cyane mugukora inzugi nidirishya nibikoresho bizigama ingufu, kandi kubikoresha biracyari binini kandi byiyongera.
Umuyoboro wa PVC
Imiyoboro ya PVC ninganda ya 2 nini mu nganda zikoreshwa cyane, Ikoreshwa ni 20% yubushobozi bwose bwo kubyaza umusaruro imbere mu Bushinwa, Umuyoboro wa PVC.
3. Filime ya PVC
Filime ya PVC yatanzwe ni iya 3 nini ikoreshwa cyane, ni hafi 10% yubushobozi bwose.
