Kev Taw Qhia
Nyob rau hauv lubmethyl methacrylateCov txheej txheem ntau lawm, kev saib xyuas kom meej ntawm monomer purity thiab reactivity yog qhov tseem ceeb rau kev polymerization tas mus li. Cov txheej txheem polymerization ntau hauv kev tsim acrylic xav tau kev tswj hwm nruj ntawm radical initiator dosing thiab kev tshem tawm cua sov.
Cov txheej txheem polymerization ntawm cov ntawv acrylic vam khom kev nyeem ntawv tiag tiag rau kev ntsuas, sib tov, thiab pov tseg kom tiv thaiv cov qhov tsis zoo thiab cov ntaub ntawv tsis raws li qhov tau teev tseg. Kev tswj qhov ceev kom raug ua rau muaj kev meej thiab kev sib xws hauv kev tsim cov ntawv acrylic.
Kev Txheeb Xyuas Txog Cov Txheej Txheem Tseem Ceeb Hauv Kev Lag Luam
Cov txheej txheem tsim cov methyl methacrylate siv catalytic methylation lossis oxidative esterification ncaj qha los tsim MMA monomer. Catalytic methylation feem ntau siv cov catalysts Mg/Ga oxide sib xyaw, ua tiav kev xaiv siab thiab cov txiaj ntsig, thaum txo cov khoom tsim tawm. Direct methylation, qauv hauv Aspen Plus, ua rau muaj kev siv rov qab zoo, tso cai rau MMA purity txog li 99.9% nrog kev siv hluav taws xob tsawg dua.
Daim duab qhia txog cov txheej txheem methyl methacrylate qhia txog cov khoom siv raw, cov kauj ruam ntxuav MMA, thiab cov theem ruaj khov. Tom qab ntawd, MMA ruaj khov raug xa mus rau cov chaw polymerization loj los ntawm cov kav dej kaw, txo qis kev ua qias tuaj thiab kev poob.
Cov txheej txheem polymerization ntawm methyl methacrylate muaj xws li cov neeg pib ua kom sov, kev tswj cua sov kom raug, thiab kev nthuav dav ntawm cov saw polymer tas mus li. Kev tswj cua sov ntawm lub reactor ua kom muaj kev hloov pauv zoo ib yam thiab tiv thaiv kev ua kom sov tsis tu ncua.
Kev tswj cov txheej txheem tsim cov ntawv acrylic nyob ntawm qhov kev ntsuas kom raug, kev sib xyaw ua ke siab, thiab kev casting scaled. Cov txheej txheem ua cov ntawv acrylic xws li kev tswj kev txias thiab kev tswj cov npuas dej yog qhov tseem ceeb rau kev meej thiab kev sib xws. Txhua kauj ruam xav tau kev saib xyuas nruj kom ruaj khov rau qhov zoo ntawm cov khoom.

Qhov Ceev Tiag Tiag Kev Sib Tw Ntsuas inAcrylicSlub suabMkev tsim khoom
Kev ntsuas qhov ceev thiab kev sib sau ua ke hauv cov txheej txheem tsim cov ntawv acrylic ntsib teeb meem tas li los ntawm cov txheej txheem dynamics thiab kev hloov pauv ntawm cov khoom siv. Qhov kub siab hauv cov cheeb tsam exothermic reactive ua rau cov sensor fouling sai dua, ua rau drift thiab calibration poob. Cov txheej txheem methyl methacrylate bulk polymerization ua rau muaj kev hloov pauv viscosity sai, cuam tshuam kev ruaj khov ntawm lub ntsuas qhov ceev thiab xav tau kev rov kho dua ntau zaus.
Cov khoom me me uas raug tshem tawm thiab kev sib cais theem thaum lub sijhawm ua cov txheej txheem polymerization ntawm daim ntawv acrylic ncaj qha txo qhov tseeb ntawm inline sensor, vim tias cov cuab yeej teb raug kev cuam tshuam los ntawm kev tawg thiab kev ntws tsis sib xws. Cov cheeb tsam hauv cov txheej txheem yuav muaj cov npuas sib txawv lossis microgel tsim, ua rau cov ntaub ntawv ceev thiab kev sib sau ua ke tsis sib xws vim muaj kev hloov pauv ib ntus.
