Kev Kho Mob Xwm Ceev

Cais tawm thaj chaw tsis huv thiab txwv kev nkag mus. Txiav tawm qhov hluav taws kub. Nws raug nquahu tias cov neeg ua haujlwm kub ntxhov tau hnav lub ntsej muag plua plav (daim npog ntsej muag lub ntsej muag tag nrho) thiab hnav cov kua qaub thiab alkali-pov thawj txhua yam. Tsis txhob kov ncaj qha xau. Qhov me me ntawm cov dej xau: kom tsis txhob muaj plua plav, siv tus pas ntsuas kom huv hauv los sib sau rau hauv lub thawv qhuav, huv, thiab npog. Kev nqus dej ntau: sib sau thiab rov ua dua lossis thauj mus rau qhov chaw pov tseg rau cov khib nyiab.

Pab:

Phthalic anhydride tam sim no dav siv hauv tshuaj lom neeg, chaw tsim tshuaj, khoom siv hluav taws xob, kev ua liaj ua teb, pleev xim, tshuaj zoo thiab lwm yam kev lag luam. Kuv lub teb chaws' s phthalic anhydride feem ntau yog siv los tsim cov phthalic acid ester plasticizers. Cov txiaj ntsig phthalic anhydride muaj kwv yees li 60% ntawm tag nrho cov kev noj ntawm phthalic anhydride, dyes thiab xim tsev rau 25%, thiab cov roj hmab tsis huv thiab lwm yam khoom lag luam muaj kwv yees li 15%. Phthalic anhydride yog ib qho tseem ceeb ntawm cov tshuaj lom neeg ua qoob loo, feem ntau yog siv los tsim cov yas yas, alkyd resins, dyes, resins tsis huv, thiab qee yam tshuaj thiab tshuaj tua kab.
