DRK121 Daim Ntawv Cua Permeability
Lus piav qhia luv luv:
DRK121 Paper Air Permeability yog siv rau kev sim cov huab cua permeability ntawm daim ntawv.Cov khoom nta Raws li cov xwm txheej, qhov nruab nrab huab cua ntws ntawm daim ntawv hauv chav tsev, nyob rau hauv chav tsev lub sij hawm thiab nyob rau hauv chav tsev siab.Daim ntawv thov khoom siv hauv kev kuaj huab cua permeability ntawm cov ntawv sib txawv (tsis muaj cov ntawv ntxhib saum npoo), xws li cov hnab ntawv cement, hnab ntawv kraft, ntawv cable, ntawv luam, ntawv lim thiab lwm yam.Cov qauv txheej txheem ISO1924/2-1985
