Nws yog cov hmoov dawb uas muaj kev sib cais saum pH ntawm5.5, thiab yog siv rau hauv cov txheej txheej enteric kom tawg sai rau hauv plab hnyuv sab sauv, rau granulation ntawm cov tshuaj hauv cov hmoov. rau kev tswj-tso tawm, thiab rau qhov chaw tshwj xeeb xa tshuaj. Nws feem ntau tso tawm hauv duodenum ntawm lub plab zom mov.
Puas yog methacrylic acid copolymer muaj kev nyab xeeb?
Methacrylic Acid yog HIGHLY CORROSIVE CHEMICAL thiab kev sib cuag tuaj yeem khaus khaus hnyav thiab hlawv daim tawv nqaij thiab qhov muag uas ua rau qhov muag puas. Ua pa Methacrylic Acid tuaj yeem ua rau lub qhov ntswg thiab caj pas. Cov qib siab tuaj yeem cuam tshuam rau lub ntsws ua rau hnoos, hawb pob thiab / lossis ua tsis taus pa.
methacrylic acid copolymer yog dab tsi?
Production. Nyob rau hauv txoj kev uas feem ntau, methacrylic acid yog npaj los ntawm acetone cyanohydrin, uas yog hloov mus rau methacrylamide sulfate siv sulfuric acid. Qhov no derivative nyob rau hauv lem yog hydrolyzed rau methacrylic acid, los yog esterified rau methyl methacrylate nyob rau hauv ib kauj ruam.
methacrylate copolymer siv rau dab tsi?
