Daim Ntawv Thov Khoom

Yav tav su:
Daim ntawv thov hauv txheej:PM, tsis muaj tshuaj lom thiab yaj tau zoo, yog siv dav ua cov kuab tshuaj thiab cov neeg sawv cev sib txuas ntawm cov kua mem, xim pleev xim thiab xim dej. Nws yog qhov tsim nyog rau benzene propylene emulsion, propylene alkene acid emulsion thiab nws cov xim emulsion, uas muaj cov yam ntxwv los ntawm kev txo qhov kub ntawm cov xim pleev xim, ua kom nws sib xyaw sai dua thiab ua kom cov xim pleev xim zoo.
Daim ntawv thov hauv tshuaj tua kab:PM feem ntau yog siv ua nruab nrab ntawm metolachlor rau kev tua tshuaj tua nroj, thiab ua tus neeg sawv cev ntawm cov tshuaj tua kab emulsion.
Lwm cov ntawv thov:PM siv tau ua cov tshuaj tiv thaiv roj, tshuaj ntxuav, tshuaj rho tawm, thiab tshuaj pleev xim rau cov hlau uas tsis yog hlau. Tsis tas li ntawd, nws siv tau ua cov khoom siv rau kev tsim cov organic, tshuaj zas xim thiab ntaub, thiab tshuaj yaj rau cov roj tig.

DPMSiv ua cov tshuaj yaj rau PVC stabilizer, nitrocellulose, ethyl cellulose, polyvinyl acetate, tshuaj yaj rau xim thiab dyestuff, thiab yog ib qho khoom xyaw ntawm cov kua nres. Nws tuaj yeem siv ua cov tshuaj yaj rau cov number case luam ntawv, xim enamel, kua txiav thiab roj ua haujlwm; ua tus neeg sawv cev sib txuas ntawm cov xim dej (feem ntau yog siv los ntawm kev sib tov); ua cov tshuaj yaj nquag ntawm cov xim dej; ua cov tshuaj yaj thiab tus neeg sawv cev sib txuas ntawm cov tshuaj ntxuav hauv tsev thiab kev lag luam, tshem tawm cov roj thiab xim, tshuaj ntxuav rau hlau thiab qhov chaw tawv; ua cov tshuaj yaj hauv paus thiab tus neeg sawv cev sib txuas ntawm cov number case luam ntawv silk-screen; ua cov tshuaj yaj thiab tus neeg sawv cev sib txuas ntawm cov ntaub vat dye; ua tus neeg sawv cev sib txuas thiab tus neeg sawv cev saib xyuas tawv nqaij hauv cov mis tshuaj pleev ib ce; ua tus neeg sawv cev stabilizer ntawm cov tshuaj tua kab thiab tus neeg sawv cev coagulating ntawm cov tshuaj ci ntsa iab hauv pem teb.
