PM:
Daim ntawv thov hauv txheej: PM, tsis tshua muaj tshuaj lom thiab muaj zog soluble, yog dav siv ua kuab tshuaj thiab txuas tus neeg sawv cev ntawm tus number case, xim pleev xim thiab xim dej xim. Nws yog qhov tsim nyog rau benzene propylene emulsion, propylene alkene acid emulsion thiab nws cov emulsion xim, uas yog tus cwj pwm los ntawm txo cov txheej kub txheej, ua kom nrawm rau nws cov cohesion thiab ua kom cov txheej nyob zoo.
Daim ntawv thov hauv tshuaj tua kab: PM yog siv feem ntau nruab nrab ntawm metolachlor rau weedicide, thiab ua tus neeg sawv cev raug rho tawm ntawm tshuaj tua kab emulsion.
Lwm yam kev siv: PM tuaj yeem siv rau hauv lub thawv tua hluav taws xob tsis muaj roj, tshuaj ntxuav kom huv, rho tawm, thiab tus neeg pleev cov tawv-tsho rau cov hlau tsis huv. Tsis tas li ntawd, nws tuaj yeem siv cov khoom siv ntawm cov tshuaj lom neeg organic, ua kom zoo nkauj ntawm dyeing thiab textile, thiab solvent ntawm cov roj spinning.

DPM yog siv los ua cov kuab rau PVC stabilizer, nitrocellulose, ethyl cellulose, polyvinyl acetate, cov kuab tshuaj rau xim thiab tshuaj pleev xim, thiab ib qho tshuaj sib xyaw ntawm cov kua nres Nws tuaj yeem raug siv los ua cov kuab tshuaj luam ntawv, pleev xim pleev xim, txiav kua txig thiab ua haujlwm roj; raws li txuas tus neeg saib xyuas ntawm cov xim pleev xim dej (feem ntau yog siv los ntawm kev sib xyaw); raws li nquag solvent ntawm dej-xim xim; raws li cov kuab tshuaj thiab txuas tus neeg sawv cev ntawm tsev neeg thiab cov tshuaj ntxuav kom huv, tshem cov roj thiab pleev xim, ntxuav rau hlau thiab tawv tawv; raws li hauv paus hnyav thiab txuas tus neeg sawv cev ntawm cov kuab-hom silk-npo luam ntawv number case; raws li hnyav thiab txuas tus sawv cev ntawm vat dye textile; raws li tus coj sawv cev thiab tus neeg sawv cev saib xyuas tawv nqaij hauv cov tshuaj pleev kom hniav zoo nkauj; raws li stabilizer ntawm cov tshuaj tua kab thiab coagulating? tus neeg sawv cev ntawm pem teb brightener.
