Guhitamo Umurongo Ukwiye Amacupa ya Divayi: Saranex na Sarantin

Ku bijyanye no kubika divayi, guhitamo icupa rifite uruhare runini mu kubungabunga ubwiza bwa divayi. Ibikoresho bibiri bikunze gukoreshwa, Saranex na Sarantin, buri kimwe gifite imiterere yihariye ikenewe mububiko butandukanye.
Saranexbikozwe muri firime nyinshi zifatanije zirimo inzoga ya Ethylene-vinyl (EVOH), itanga inzitizi ya ogisijeni igereranije. Hamwe nigipimo cya ogisijeni (OTR) kingana namasaha 1-3 cc / m² / 24, Saranex yemerera ogisijeni nkeya gucengera icupa, rishobora kwihuta gukura kwa divayi. Ibi bituma biba byiza kuri divayi igenewe gukoreshwa mugihe gito. Igipimo cyo gukwirakwiza imyuka y’amazi (WVTR) ya Saranex nayo iragereranije, hafi 0.5-1.5 g / m² / amasaha 24, ikwiranye na divayi izishimira mu mezi make.
SarantinKu rundi ruhande, bikozwe mu bikoresho bya PVC bifite inzitizi nyinshi zifite ubushobozi buke cyane, hamwe na OTR munsi ya 0.2-0.5 cc / m² / amasaha 24, bigabanya umuvuduko wa okiside kugirango urinde uburyohe bwa vino. WVTR nayo iri hasi, mubisanzwe hafi 0.1-0.3 g / m² / amasaha 24, bigatuma Sarantin iba nziza kuri vino nziza cyane igenewe kubikwa igihe kirekire. Urebye imiterere ya barrière isumba izindi, Sarantin ikoreshwa cyane muri divayi igenewe gusaza imyaka, ikemeza ko ubuziranenge butagerwaho n’umwuka wa ogisijeni.
Muncamake, Saranex ikwiranye na vino igenewe kunywa igihe gito, mugihe Sarantin nibyiza kuri divayi nziza cyane igenewe kubikwa. Muguhitamo umurongo ukwiye, abakora divayi barashobora guhaza neza ibyo kubika no kunywa kubakoresha.
