Valve ya plastike ni ubwoko bwa valve nini, ifite ibyiza byo kurwanya ruswa, uburemere bworoshye, kwambara kurwanya, nibindi birakoreshwa cyane mubuvuzi, petrochemical, kurinda ibidukikije nizindi ngamba. Ibikurikira ni amateka yiterambere ya plastike.
Mu myaka ya za 1950, hamwe n'iterambere ryihuse ryinganda zumutima, icyifuzo cya valve buhoro buhoro cyiyongereye. Muri iki gihe, ibikoresho bya plastike byakoreshwaga cyane mumwanya winganda, bityo abashakashatsi bamwe batangira kwiga uburyo bwo gukoresha ibikoresho bya plastike mugikorwa cyinshuke. Ibikoresho bya plastike kare byakorewe hakoreshejwe ibikoresho bya chloride (PVC), bifite imbaraga nziza cyane, ariko bikwiranye na imashini nke kandi bikwiranye nigitutu cyo hasi nubushyuhe buke.
Mu myaka ya za 1960, hamwe no guteza imbere ikoranabuhanga rya phostics, Polypropylene (PP), PolytetrafürouoRyylene (PTFE) nibindi bikoresho byakoreshejwe mugukora plastike. Ibi bikoresho bifite imiterere yubukanishi hamwe no kurwanya ruswa, kandi birashobora kumenyera kugeza kumwanya wakazi.
Mu myaka ya za 70, hamwe no gukura kw'ikoranabuhanga rya plastike, hatangijwe indangagaciro zitandukanye za pulasitike. guhuza no gusaba byinshi.
Mu ntangiriro z'ikinyejana cya 21, hamwe no kumenya uburinzi bw'ibidukikije, ibisabwa kuri indangagaciro bigenda biba hejuru ndetse no hejuru. Muri iki gihe, hakoreshejwe ibikoresho bimwe bya pulasitike byakoreshejwe mu gukora indangagaciro, nka polyerketone (peek), polimide (pi) nibindi bikoresho byo murwego rwohejuru. Ibi bikoresho bifite imiterere yubukanishi hamwe no kurwanya ruswa, kandi birashobora guhura nibibazo bisaba.
Muri make, hamwe no guteza imbere inganda za shimi hamwe no guhora duhangana kwikoranabuhanga rya plastiki, indangagaciro za plastiki bahuye niterambere ryibikoresho bya plastiki bivuye mubikoresho bya PVC hakiri kare kugeza ubu, buri gihe kuzamura imiti yabo ya ruswa, bihora biteza imbere kurwanya ruswa, imitungo nubugizi bwamaniki nubutaka bwa Gusaba, kuba ibikoresho byingenzi kandi byingirakamaro kubikoresho byimiti, petrochemical hamwe ninganda zo kurengera ibidukikije.
