ASTM D3985 Standard Test Method for Oxygen Gas Transmission Rate through Yas Film and Sheeting using a Coulometric Sensor. Txoj kev sim no suav nrog cov txheej txheem rau kev txiav txim siab ntawm tus nqi tsis tu ncua ntawm kev xa cov pa oxygen los ntawm cov yas hauv daim ntawv ntawm zaj duab xis, ntawv, laminates, coextrusion, los yog cov ntaub ntawv yas-coated los yog ntaub.
Test Principple
Cov qauv tsim thiab kev ua haujlwm ntawm peb lub cuab yeej yog raws li ASTM D 3985 tus qauv.
Cov roj nitrogen qhuav yog rhais los ntawm lub chamber, qhov twg cov yeeb yaj kiab sim ua raws li daim nyias nyias cais cov kwj dej ntawm cov kwj dej ntawm sab nraud. Qhov sib txawv ntawm ib nrab ua rau lub zog tsav rau oxygen molecules kom diffuse los ntawm zaj duab xis mus rau sab qis. Cov yeeb yaj kiab thaiv kev txiav txim siab tus nqi ntawm oxygen permeation, uas yog ntsuas tsis tu ncua los ntawm coulometric sensor nyob rau hauv cov kwj tawm ntawm sab nitrogen. Qhov kev sim ua tiav thaum qhov sib npaug, lossis lub xeev khov kho, ua tiav; uas yog, thaum lub sensor pom ib qho tsis tu ncua ntawm cov pa oxygen hauv cov cab cab nitrogen. Tus nqi ntawm oxygen permeating los ntawm cov qauv tsis hloov. Tus nqi no yog tus qauv OTR thiab tau sau tseg rau hauv units ntawm cc/100 in2/24 hr lossis cc/m2/24 hr ntawm 73 ° F (23 ° C), 0% RH.
