Maleic anhydride muaj cov yam ntxwv ntawm kev ruaj khov zoo thiab kev ua haujlwm zoo hauv cov khoom siv cob. Nws ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm ntau yam resins xws li unsaturated polyester resins, alkyd resins, thiab hloov phenolic resins. Maleic anhydride qhov zoo heev reactivity thiab compatibility nrog ntau hom polymers txhim khu cov neeg kho tshuab thiab thermal zog ntawm resin, ua rau nws haum rau ntau yam kev siv.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm maleic anhydride yog nws cov dej solubility, uas tuaj yeem tsim cov txiv neej acid thaum yaj hauv dej. Cov yam ntxwv no ua rau nws yooj yim los tswj thiab sib koom ua ke rau hauv cov dej-raws li cov tshuab, ntxiv kev nthuav dav nws siv hauv kev tsim cov dej-raws li resins. Tsis tas li ntawd, cov txiv neej anhydride zoo li cov muaju dawb nrog qhov ntom ntawm 1.484 g / cm3, muab cov ntsiab lus pom rau nws cov purity thiab zoo.
Ua kom muaj kev nyab xeeb ntawm kev tuav cov txiv neej anhydride yog qhov tseem ceeb tshaj plaws. Nws raug nquahu kom ua raws li cov lus qhia txog kev nyab xeeb suav nrog S22 (Tsis txhob ua pa plua plav), S26 (thaum sib cuag nrog lub qhov muag, yaug tam sim), S36/37/39 (Xaiv cov khaub ncaws tiv thaiv tsim nyog, hnab looj tes thiab tiv thaiv qhov muag / ntsej muag) thiab S45 ( Thaum muaj xwm txheej lossis tsis xis nyob, nrhiav kev kho mob tam sim ntawd). Lub cim kev phom sij C qhia tias nws yog ib qho kev phom sij rau kev noj qab haus huv thiab yuav tsum tau ua raws li. Cov lus hais txog kev puas tsuaj muaj xws li R22 (muaj teeb meem yog tias nqos), R34 (ua rau kub hnyiab) thiab R42/43 (tej zaum yuav ua rau muaj kev hnov mob los ntawm kev nqus pa thiab sib chwv ntawm daim tawv nqaij).
Maleic anhydride muaj qhov ruaj khov zoo thiab siv dav hauv cov khoom siv cob, thiab yog ib qho tseem ceeb hauv kev lag luam tshuaj. Nws muaj cov txiaj ntsig tseem ceeb xws li kev txhim kho cov khoom siv thiab ua kom muaj dej raws li cov qauv. Nws versatility thiab reactivity ua rau nws zoo tagnrho rau ntau yam kev lag luam thiab kev lag luam daim ntawv thov, ua rau kev tsim cov khoom zoo thiab ruaj khov.
Hauv cov ntsiab lus, maleic anhydride, tseem hu ua MA, yog cov khoom siv dav siv hauv cov khoom siv cob. Maleic anhydride, nrog nws cov khoom ruaj khov, dej solubility, thiab zoo heev compatibility nrog polymers, txhim khu kev ua tau zoo ntawm resin thiab ua rau nws haum rau ntau yam kev siv. Txawm li cas los xij, vim muaj kev phom sij rau kev noj qab haus huv ntawm maleic anhydride, tuav cov txiv neej anhydride yuav tsum tau ua raws li cov lus qhia kev nyab xeeb. Zuag qhia tag nrho, maleic anhydride plays lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj thiab yog qhov tseem ceeb rau kev tsim cov khoom ua haujlwm siab.
