Khoom noj khoom haus- qib kraft ntawv tsis yog ntawv zoo tib yam; nws yog tsim los ntawm ntev - fiber ntau ntoo pulp los ntawm siab - lub zog nias thiab cov nroj tsuag - raws li txheej txheem txheej. Its oil resistance comes from the physical barrier formed by the dense interweaving of fibers, rather than a chemical coating; nws cov dej tsis kam tso siab rau kev sib koom ua ke ntawm cov lignin ntuj thiab nws cov qauv microporous- dej tsis yooj yim nkag mus, tab sis nws tswj kev ua pa nruab nrab, tiv thaiv condensation buildup.
Cov khoom no tsis tso cov yas yas, tsis tawm cov ntxhiab tsw thaum cua sov, thiab ua tau raws li GB 4806.8-2022 tus qauv rau daim ntawv tiv tauj zaub mov, ua rau nws yog ib qho zoo tagnrho rau cov zaub mov, zaub nyoos, thiab kua ntses. Nws tsis cia siab rau ib txheej ntawm cov yas kom "dhuav" nws tus kheej li ib puag ncig tus phooj ywg; es, nws tsis kam cuam tshuam los ntawm qhov chaw ntawm fiber ntau.
