Tus neeg sawv cev tiv thaiv dej ntawm daim ntawv
Haum rau kev tsim cov ntoo pulp, reed pulp, Asmeskas pov tseg pulp ntau yam ntawv kab lis kev cai, ntawv board, ntawv xov xwm, txiv hmab txiv ntoo hnab ntawv thiab ntawv qhwv thiab lwm yam ntawv, tuaj yeem siv rau hauv qhov ntau PH tus nqi (7-9), qhov tsim nyog tshaj plaws rau PH (7.5-8.5), tuaj yeem siv calcium carbonate filler, Nws tuaj yeem hloov cov kua qaub ib txwm muaj ntawm rosin thiab AKD neutral sizing. Qhov ntxiv ntawm cov khoom no yog 0.1-0.15% ntawm cov pulp qhuav kiag li (qhov qhuav ntawm cov khoom no). Thaum siv, dilute nws 5-10 zaug thiab ntxiv rau hauv lub tank sib tov slurry thiab do nws kom sib npaug.
Rau daim ntawv uas muaj kev sau, qhov kev sib law liag ntxiv yog ntxiv cov khoom sau ua ntej thiab tom qab ntawd ntxiv cov tshuaj tiv thaiv dej.
Daim ntawv nruab nrab, ua kom daim ntawv muaj zog dua, txo qhov tshwm sim ntawm hmoov, plaub hau poob, txhim kho kev luam ntawv. Txhim kho kev khaws cia cov fibers zoo thiab cov khoom ntxiv, txo kev siv pulp thiab txo cov nqi. Txhim kho qhov zoo ntawm daim ntawv, xws li lub zog ntawm qhov chaw, kev nruj, kev tiv thaiv kev quav, kev loj me, kev pom tseeb, qhov du ntawm qhov chaw thiab lwm yam cim qhia ntawm daim ntawv zoo dua li cov cim qhia txog kev loj me ntawm cov kua qaub thiab cov cim qhia txog kev loj me ntawm cov xim nruab nrab. Ua kom yooj yim rau kev loj me, txhim kho kev ua haujlwm ntawm lub tshuab ntawv, thiab tsis tsim cov teeb meem ntawv.
