Nyuj cov roj cov ntaub ntawv nplaum cov khoom siv feem ntau hu ua cov sulfuric acid ntawv, tom qab pulp tshwj xeeb kom ntxiv cov phau ntawv tshwj xeeb. Rol ntawv feem ntau yog cov ntawv sau, thaum nplaum yog cov ntawv nplaum khawm, feem ntau yog cov kua nplaum thiab cov ntawv. Ob yam khoom siv feem ntau tsis muaj feem xyuam rau cov siv tau. Thov piav qhia cov kev xav tau tshwj xeeb lossis keeb kwm yav dhau los. Kuv yuav sim kuv qhov zoo tshaj plaws los pab koj nrhiav cov ntaub ntawv cuam tshuam. Raws li cov chaw tsim khoom lag luam, peb tseem tuaj yeem tsim cov ntawv nplaum, cov ntawv xas, cov ntawv siv tshuaj ntsuab, cov ntawv kho mob, cov ntaub ntawv hluav taws xob, cov hluavtaws hluavtaws, inkjet tus tsiaj Adhesive thiab lwm yam khoom.Tto Xav paub ntau ntxiv, thov sab laj.
