Gutezimbere ububiko bwa plastike

Umuyoboro wa plastiki nubwoko bukoreshwa cyane bwa valve, bufite ibyiza byo kurwanya ruswa, uburemere bworoshye, kwambara nabi, nibindi bikoreshwa cyane mubumashini, peteroli, kurengera ibidukikije nizindi nganda.Ibikurikira namateka yiterambere rya valve ya plastike.

Mu myaka ya za 1950, hamwe n’iterambere ryihuse ry’inganda z’imiti, icyifuzo cya valve cyiyongereye buhoro buhoro.Muri iki gihe, ibikoresho bya pulasitike byakoreshejwe cyane mu nganda, ku buryo bamwe mu ba injeniyeri batangiye kwiga uburyo bwo gukoresha ibikoresho bya pulasitike mu gukora indangagaciro.Imyanda ya pulasitike yo hambere yakozwe cyane cyane ikoresheje ibikoresho bya polyvinyl chloride (PVC), ifite imbaraga zo kurwanya ruswa, ariko imiterere yubukanishi irakennye kandi ikwiranye gusa n’umuvuduko muke hamwe n’ubushyuhe buke.

Mu myaka ya za 1960, hamwe n’iterambere rikomeje ry’ikoranabuhanga rya plastiki, polypropilene (PP), polytetrafluoroethylene (PTFE) n’ibindi bikoresho byakoreshwaga mu gukora indangagaciro za plastiki.Ibi bikoresho bifite imiterere yubukanishi hamwe no kurwanya ruswa, kandi birashobora guhuza nurwego runini rwibidukikije.

Mu myaka ya za 70, hamwe no gukura kwikoranabuhanga rya plastike ya plastike, hatangijwe ububiko butandukanye bwa plastike bushya, nka fluor polyvinyl fluoride (PVDF), ibyuma byikirahure, nibindi .. Ibi bikoresho bishya bifite imiti ihamye yimiti nubukanishi, kandi birashobora ihuze nibikorwa byinshi bisaba akazi.

Mu ntangiriro z'ikinyejana cya 21, hamwe no kurushaho gukangurira kurengera ibidukikije, ibisabwa ku mibande bigenda byiyongera.Muri iki gihe, ibikoresho bimwe na bimwe bya pulasitiki byakoreshejwe mu gukora indangagaciro, nka polyetherketone (PEEK), polyimide (PI) n’ibindi bikoresho bya pulasitiki bikora cyane.Ibi bikoresho bifite imiterere myiza yubukanishi no kurwanya ruswa, kandi birashobora guhura nibikorwa bikenewe cyane.

Muri make, hamwe niterambere ryinganda zimiti no guhanga udushya twubuhanga bwa plastiki, ububiko bwa plastike bwiboneye iterambere ryibikoresho bya pulasitiki bikora neza kuva mubikoresho bya PVC bya mbere kugeza ubu, bihora bitezimbere kurwanya ruswa, imiterere yubukanishi nubunini bwa kubishyira mu bikorwa, kuba ibikoresho byingenzi kandi byingirakamaro mu nganda z’imiti, peteroli n’ibidukikije.
