Kev kho mob xwm txheej ceev

Cais thaj chaw muaj kab mob thiab txwv kev nkag mus. Txiav tawm qhov hluav taws kub. Nws raug pom zoo tias cov neeg ua haujlwm kho mob xwm txheej ceev yuav hnav lub ntsej muag plua plav (lub ntsej muag tag nrho) thiab hnav cov kua qaub thiab alkali- pov thawj zuag qhia tag nrho. Tsis txhob kov cov xau ncaj qha. Ib qho me me ntawm cov dej xau: tsis txhob muaj plua plav, siv lub duav huv los sau rau hauv lub thawv qhuav, huv, npog. Cov dej xau ntau: sau thiab rov ua dua lossis thauj mus rau qhov chaw pov tseg pov tseg.

Kev siv:

Phthalic anhydride tam sim no tau siv dav hauv tshuaj, tshuaj, khoom siv hluav taws xob, kev ua liaj ua teb, txheej txheej, tshuaj zoo thiab lwm yam kev lag luam. kuv lub teb chaws phthalic anhydride yog siv los tsim phthalic acid ester plasticizers. Cov txiaj ntsig phthalic anhydride suav txog li 60% ntawm tag nrho kev noj phthalic anhydride, dyes thiab pleev xim rau 25%, thiab unsaturated resins thiab lwm yam khoom muaj txog li 15%. Phthalic anhydride yog ib qho tseem ceeb ntawm cov organic chemical raw khoom, feem ntau yog siv los tsim cov yas yas, alkyd resins, dyes, unsaturated resins, thiab qee yam tshuaj thiab tshuaj tua kab.
