Daim Ntawv Thov Khoom

PnBFeem ntau yog siv los ua tus neeg ntxuav rau cov kuab paug hnyav. Nws tuaj yeem yaj cov roj thiab cov roj sib txuas tau zoo thiab ua rau nws tus kheej haum rau cov mis ntawm tsev neeg thiab kev lag luam. Ib feem yaj hauv dej, PnB tuaj yeem yaj feem ntau cov kuab tshuaj nrog daim ntawv thov raws li hauv qab no:

① ua cov tshuaj ntxuav hauv tsev thiab kev lag luam, tshem tawm cov roj thiab xim, tus neeg sawv cev sib txuas thiab cov kuab tshuaj ntawm cov hlau thiab cov tshuaj ntxuav tawv;

② ua tus neeg sawv cev sib txuas zoo thiab cov kuab tshuaj ntawm cov txheej txheem txo dej;

③ ua tus neeg sawv cev coagulating zoo ntawm cov xim emulsion dej;

④ ua cov kuab tshuaj ntawm cov xim pleev xim;

⑤ ua tshuaj nruab nrab rau ester, solvent thiab plasticizer manufacture.

DPnB
Daim ntawv thov hauv txheej:Ua ib qho ntawm cov khoom siv ua zaj duab xis zoo tshaj plaws ntawm cov xim pleev xim dej, DPnB tuaj yeem siv ua coagulant ntawm acrylic resin, phenylethylene acrylic resin thiab polyvinyl acetate muab kev ua tau zoo heev rau zaj duab xis pleev xim.
Daim ntawv thov hauv kev ntxuav:nws siv tau rau cov tshuaj ntxuav tshwj xeeb tshaj yog rau cov uas xav tau qhov ceev qis, xws li cov tshuaj tshem quav ciab thiab cov tshuaj ntxuav hauv pem teb. Ua tus neeg sawv cev zoo rau kev siv roj thiab roj, DPnB tuaj yeem siv ua cov tshuaj tshem xim thiab tshem cov roj tsiaj.
Lwm daim ntawv thov:DPnB kuj tseem siv tau rau hauv cov khoom ua liaj ua teb, tshuaj pleev ib ce, kua mem hluav taws xob thiab ntaub.
