Kev ua haujlwm lom neeg: MES (2-Morpholinoethanesulphonicacid) yog ib qho zwitterionic tsis muaj txiaj ntsig zoo hauv pH ntau ntawm 5.5-7.7.Raws li ib tug zoo tus tsis, MES yog dav siv nyob rau hauv cov nroj tsuag media, reagent daws thiab physiological thwmsim los kho pH.
Chemical Properties: Lub teeb daj muab tshuaj txhuam.Lub teeb nyem yog 149 ° C thiab qhov taw tes ntws yog 60 ° C.1% dej solubility ntawm 25 ° C.Nws muaj cov tshuaj tua kab mob siab, zoo heev calcium xab npum dispersibility thiab chemicalbook tsis kam rau cov dej tawv.Zoo lom solubility.
Daim ntawv thov: Cov khoom no yog siv los ua calcium xab npum dispersant hauv xab npum thiab xab npum.tuaj yeem hloov sodium tripolyphosphate ua cov tshuaj uas tsis muaj phosphorus lossis tsis-phosphorus detergent.Kuj tseem siv tau ua ib qho active hauv cov kua ntxhua.Nyob rau hauv kev lag luam, nws yog siv los ua ib tug nruab nrab-bubble ntxhia flotation tus neeg saib xyuas.Nyob rau hauv tawv degreasing, nws yog siv raws li dispersant thiab wetting tus neeg sawv cev nyob rau hauv dyes, pigments thiab tshuaj tua kab.Nws yog siv los ua tus neeg sawv cev deinking hauv kev lag luam luam ntawv.
Kev Siv: tuaj yeem siv ua tshuaj ntxuav lub ntsej muag, tshuaj zawv plaub hau ua npuas dej, tshuaj ntxuav tais diav, xab npum raw khoom, thiab lwm yam.
Siv: Cov khoom siv roj ntsha tsis zoo, siv rau hauv cov khoom siv tshuaj ntsuam xyuas biochemical, cov khoom siv DNA / RNA extraction thiab PCR cov khoom siv kuaj mob.
