Gusaba TPS bizakomeza gutezwa imbere kugirango byuzuze ibisabwa ku isoko.

Ibyingenzi Byibanze nuburyo bukoreshwa muri TPS EVOH Resin mugupakira ibiryo

Isosiyete ya TPS ya EVOH (Ethylene Vinyl Alcool) isobanura intambwe mu buhanga bwo gupakira ibiryo, cyane cyane mubikoresho bikoreshwa cyane. Imiterere yihariye ya molekuline, igaragaramo amatsinda ya hydroxyl (-OH) buri gihe kumurongo wa polymer, itera inzitizi idasanzwe irwanya ogisijeni nizindi myuka ishobora guhungabanya ubuziranenge bwibiribwa. Ibi bintu byingenzi biranga EVOH ikintu ntagereranywa mubipfunyika byibiribwa bigezweho, aho kubungabunga ibicuruzwa bishya no kongera igihe cyo kubaho ni byo byingenzi.

Mubikoresho bikarishye, resin ya EVOH ya TPS isanzwe ishyirwa mubikorwa byinshi, aho ishyizwe hagati ya polyethylene (PE) cyangwa polypropilene (PP). Iboneza ni ngombwa kuko mugihe EVOH itanga inzitizi zisumba izindi, bisaba kurinda ubushuhe kugirango ikomeze imikorere yayo. Ibice byo hanze bikora iki gikorwa cyo kurinda, byemeza ko inzitizi zihoraho mubuzima bwa kontineri. Imiterere yerekana umuvuduko udasanzwe wo kwanduza ogisijeni uri munsi ya 0.01-0.1 cc / m² / kumunsi, kurwanya cyane amavuta hamwe n’umusemburo kama, hamwe no gukorera mu mucyo no kurabagirana.

Gutunganya TPS EVOH resin bisaba kugenzura neza nibikoresho byihariye kugirango bigere kubisubizo byiza. Isosiyete itanga ubufasha bwuzuye bwa tekiniki, harimo umurongo ngenderwaho urambuye wo gutunganya ubushyuhe (mubisanzwe 190-230 ° C), ibisabwa byo kugenzura ubushuhe, hamwe no gutoranya ibiti byubatswe munzego nyinshi. Mugihe ibiciro byambere bishobora kuba hejuru ya plastiki zisanzwe, inyungu zubukungu ni nyinshi mugihe urebye igihe kirekire cyo kugabanuka no kugabanya imyanda y'ibiribwa. Izi nyungu zatumye EVOH ya TPS isubirwamo ihitamo kubakora ibicuruzwa bashaka ibisubizo byimbaraga zikomeye mubikoresho byibiribwa bikomeye.
