Polycarboxylate Superplasticizer PCEyog tsim ntawm macromolecular sib sau ua ke nrog sulfonic acid pawg, cov pab pawg tsiaj cov roj av, thiab lwm cov pab pawg ua ntej, thiab lwm yam, thiab lwm yam, thiab lwm yam.

Cov ntaub ntawv nyoos loj yuav tsum rau cov synthesis ntawmSiv Tshuaj Dej Reducer Polycarboxylate Superplasticierare: methacrylic acid, acrylic acid, ethyl acrylate, hydroxyethyl acrylate, sodium allyl sulfonate, methyl methacrylate, 2-acrylamido- 2-Methacrylic acid, methoxy polyoxyethylene methacrylate, ethoxy polyethylene glycol acrylate, allyl ether, etc. The initiators that can be used nyob rau hauv Polymerization txheej yog: Persulfate-based-based premiaors, benzoyl peroxide, AzobisisiButyl cyanide; Saw cov neeg hloov chaw hloov chaw: 3-Mercaptopropionic acid, mercaptoacetic acid, thiab lwm yam.

Lub polycarboxylic acid dej txo tus neeg sawv cev Cov qauv hluavtaws hluavtaws puag ncig yog: Hauv ib puag ncig lub zog nruab nrog lub ntsuas hluav taws xob, thiab lub tshuab muag khoom noj khoom haus qis dua, thiab cov khoom noj khoom haus tshiab Thaum xaiv cov polymerization monomer, University nrog nws tus lej sib tw yuav tsum tau txiav txim siab tag nrho. Cov tshuaj tiv thaiv cua kub tuaj yeem txiav txim siab raws li cov tshuaj tiv thaiv tshwj xeeb monomer. Feem ntau, qhov kub hauv qhov ntsuas kub ntawm 70 ~ 95 ℃ Xaiv tau raws li cov tshuaj tiv thaiv kub.

Tso cov kev daws teeb meem tsis pub dhau ib teev, thiab tom qab ntawd tso nws tsis pub dhau 20 ° Ntxiv rau qhov ntsuas kub ntxiv los ntawm 1H, thiab tom qab qhov ntsuas kub nce mus rau 40 ° C, neutralize thiab paug.
