Cov chaw tsim khoom ntawm pob tshab PET tiv thaiv zaj duab xis tau hais rau peb tias yog tias muaj tev tawm thaum muab cov khoom pov tseg, peb yuav tsum tsis txhob xav txog cov khoom tsis tsim nyog. Qhov no tej zaum yuav tshwm sim los ntawm tsis txaus viscosity. Yog li ntawd, hloov lub siab-viscosity pob tshab PET tiv thaiv zaj duab xis yog qhov zoo tshaj plaws.
Muaj qee cov lus qhia thiab kev siv dag zog rau kev siv txhua yam khoom siv hauv lub neej, thiab tseem muaj cov lus qhia sib txawv rau kev siv cov viscosity ntawm pob tshab PET tiv thaiv zaj duab xis. Raws li peb txhua tus paub, niaj hnub no lub pob tshab PET tiv thaiv zaj duab xis ua lag luam, lawv tau siv ntau txoj hauv kev nyob ntawm lawv qhov viscosity. Piv txwv li, low-viscosity pob tshab PET tiv thaiv zaj duab xis tsuas yog siv rau pasting ntawm cov yas. Ntawm chav kawm, raws li viscosity nce, cov ntaub ntawv pasting kuj yuav txawv. Vim li no, pob tshab PET tiv thaiv zaj duab xis manufacturers coj peb cov lus qhia raws li qib ntawm adhesion.
Yog tias peb tuaj yeem pom cov qauv viscosity ntawm pob tshab PET tiv thaiv zaj duab xis, ces peb tuaj yeem txiav txim siab cov khoom yuav tsum tau muab pov tseg thiab tiv thaiv raws li qhov viscosity. Qhov peb yuav tsum nco ntsoov yog qhov siab dua qhov viscosity, ntau cov khoom uas tuaj yeem pasted, thiab ntau cov khoom uas tsis pasted. Cov khoom sib deev kuj tuaj yeem lo tau yooj yim. Piv txwv li, high-viscosity pob tshab PET tiv thaiv zaj duab xis tuaj yeem muab tso rau ntawm daim hlau ntxhib-grained aluminium.
