> Roj resistant txoj siv yog nqa cov khoom thiab cov khoom coated nrog lub tshuab roj, hnyav-roj kho thee hauv cov chaw ua noj thiab hluav taws xob tsim cov nroj tsuag, taum daffodils, ntses nqaij thiab lwm yam khoom siv roj.Cov ntaub ntawv no muaj cov tsis muaj polar organic hnyav thiab roj.
> Txoj siv sia, sib xyaw ntawm cov roj resistant hluavtaws roj hmab, muaj kev tiv thaiv zoo rau kev puas tsuaj tshwm sim thaum xa cov roj paug lossis cov khoom siv kho mob.
> Roj resistant conveyor siv tau muab faib ua ob hom raws li cov khoom siv: MOR (Ordinary type) thiab SOR (Heat and oil resistant).
