Gusubiramo polyvinyl chloride

Polyvinyl chloride ni imwe muri pulasitiki eshanu zikomeye ku isi zikoreshwa muri rusange. Bitewe n'uko ihendutse mu gukora ugereranyije na polyethylene n'ibyuma bimwe na bimwe, hamwe n'imikorere yayo myiza yo gutunganya ndetse n'imiterere y'ibicuruzwa n'imiti, ishobora guhaza ibyifuzo byo gutegura bikomeye kugeza ku byoroshye, byoroshye, bya fibre, byo gusiga irangi n'ibindi, kandi ikoreshwa cyane mu nzego zitandukanye nko mu nganda, mu buhinzi no mu bwubatsi. Uburyo bwo kongera gukoresha imyanda ya polyvinyl chloride ni ingenzi cyane.
1. Kuvugurura
Ubwa mbere, kuvugurura imyanda mu buryo butaziguye bishobora gukorwa. Kuvugurura imyanda mu buryo butaziguye bivuga gutunganya no gushushanya imyanda mu buryo butaziguye binyuze mu gusukura, gusya no kuyishyira muri pulasitiki bitabaye ngombwa ko habaho impinduka zitandukanye, cyangwa gutunganya no gushushanya ibicuruzwa binyuze mu gusya. Byongeye kandi, ishobora no guhindurwa no kuvugururwa. Guhindura no kuvugurura pulasitiki ishaje bivuga guhindura imiterere n'imiti bya pulasitiki yasubiwemo mbere yo kuyitunganya no kuyirema. Guhindura bishobora kugabanywamo guhindura imiterere n'imiti. Kuzuza, fibre composite, no gukurura mu kuvanga ni bwo buryo bw'ingenzi bwo guhindura imiterere ya PVC. Guhindura kuzuza bivuga uburyo bwo guhindura imiterere y'uduce duto twuzuza hamwe na modulus nyinshi cyane muri polymer. Guhindura fibre composite reinforcement bivuga uburyo bwo guhindura modulus nyinshi n'imigozi ikomeye cyangwa iy'ubukorikori muri polymer, bityo bikanoza cyane imiterere y'ibicuruzwa. Guhindura imiterere ya PVC mu buryo bwa shimi bigerwaho binyuze mu guhindura imiterere ya PVC binyuze mu buryo bumwe bwa shimi.
2. Gukuraho no gukoresha hydrogen chloride
PVC irimo chlorine ingana na 59%. Bitandukanye n'izindi polima za karuboni, uruhererekane rw'amashami ya PVC rucika mbere y'uruhererekane rukuru mu gihe cyo gucika, bigatuma habaho gaze nyinshi ya hydrogen chloride, izangiza ibikoresho, ikarandura uburozi bwa Catalyst, kandi ikagira ingaruka ku bwiza bw'ibicuruzwa byacitse. Kubwibyo, uburyo bwo gukuraho hydrogène chloride bugomba gukorwa mu gihe cyo gucika kwa PVC.
3. Gutwika PVC kugira ngo ukoreshe ubushyuhe na gazi ya chlorine
Ku pulasitiki zifunze zirimo PVC, imiterere yo gutanga ubushyuhe bwinshi ikoreshwa mu kuzivanga n'imyanda itandukanye isharira no gukora ibicanwa bikomeye bifite ingano imwe y'uduce. Ibi ntibifasha gusa kubika no gutwara, ahubwo binasimbura ibicanwa bikoreshwa mu byuma bitwika amakara n'amatanura yo mu nganda, kandi bigabanya chlorine kugira ngo byongere imikorere myiza y'ubushyuhe.
