PET ni iki? -Isesengura ryuzuye rya Polyethylene Terephthalate
PET, cyangwa Polyethylene Terephthalate, ni ibikoresho bya polymer bikoreshwa cyane mu nganda zikora imiti. Muri iyi ngingo, tuzatanga isesengura ryimbitse ryibisobanuro bya PET, aho bikoreshwa, inzira yumusaruro nibyiza byayo, kugirango duhe abasomyi gusobanukirwa byimazeyo PET nkibikoresho byingenzi.
Ibisobanuro nibintu byibanze bya PET
PET ni iki? Muburyo bwa chimique, PET ni polimoplastique polymer yakozwe na polymerisation ya aside terephthalic na Ethylene glycol. Imiterere yimiti ya PET itanga imiterere yubukanishi nkimbaraga nyinshi, kurwanya ubushyuhe no gukorera mu mucyo. Iyi mitungo ituma PET ibikoresho byo guhitamo muburyo bwinshi bwo gusaba, cyane cyane murwego rwo gupakira.
Ibice byingenzi byo gusaba PET
PET ikoreshwa muburyo butandukanye bwa porogaramu, yibanda ku bice bibiri by'ingenzi: ibikoresho byo gupakira no gukora fibre. Mu nganda zipakira, PET ikoreshwa cyane mugukora ibicuruzwa nkamacupa ya pulasitike, ibikoresho byamafunguro na firime, aho gukorera mu mucyo hamwe n’imiterere myiza ya bariyeri yemeza ko ibiryo biri muri paki biguma ari bishya.PET ikoreshwa kandi nkibikoresho fatizo bya fibre synthique, ikoreshwa cyane mu nganda z’imyenda, cyane cyane mu gukora fibre polyester. Imyenda ikozwe muri fibre ya polyester iroroshye kwambara, yoroshye gukaraba kandi byihuse gukama, bigatuma biba byiza kwambara buri munsi.
Ibikorwa bya PET
Gusobanukirwa icyo PET nayo isaba kureba byimbitse kubikorwa byayo, bikorwa muburyo bubiri: intambwe imwe (esterification itaziguye) nintambwe ebyiri (guhana ester). Mubikorwa byintambwe imwe, aside terephthalic ihita ikorwa na Ethylene glycol mubushyuhe bwinshi hamwe nigitutu cyo kubyara PET, mugihe mugihe cyintambwe ebyiri, estylene glycol esters yabanje gukorwa, hanyuma hakorwa polycondensation kugirango habeho PET. Hatitawe kuburyo bwakoreshejwe, ibicuruzwa byanyuma bigomba gukorerwa muburyo bwo gutunganya, kubibumbabumbwa, kubitondekanya, kubibumbabumbwa, kubitondekanya, kubitondekanya, kubitondekanya, kubibumbabumbwa, kubitondekanya, kubitondekanya, kubitondekanya.
Ibyiza no Kuramba kwa PET
PET ni iki? Duhereye ku buryo burambye, ibyiza bya PET biri muburyo bwiza bwo gusubiramo; Ibicuruzwa bya PET birashobora gutunganywa hifashishijwe pyrolysis, gutunganya imiti nubundi buryo bwo kugabanya umwanda w’ibidukikije, kandi imbaraga za PET n’umutungo woroheje na byo birayiha inyungu mu kugabanya imikoreshereze y’ibikoresho n’ibiciro byo gutwara. Ibiranga bituma PET imwe mubikoresho byingirakamaro mu nganda zigezweho.
Umwanzuro
Mu ncamake, PET ni iki? Nibikorwa byimikorere ya polymer hamwe nibikorwa byinshi.PET igira uruhare runini munganda zigezweho kubera imiterere myiza ya fiziki ya chimique, uburyo bwinshi bwo kuyikoresha no kuyisubiramo neza. Haba mubikoresho byo gupakira mubuzima bwa buri munsi cyangwa gukora fibre mu nganda z’imyenda, imbaraga za PET ziri hose. Kubwibyo, gusobanukirwa byimbitse icyo PET ningirakamaro mugusobanukirwa imigendekere yibikoresho bya chimique bigezweho.
