Polycarboxylate Superplasticizer inonyanya kurongedzerwa nema unsaturated monomers pasi pechiito chevatangi, uye maketani eparutivi ane mapoka anoshanda anobatanidzwa pacheni huru yepolymer, kuitira kuti ive nemabasa ekushanda kwepamusoro, kudzora kurasikirwa kwekudonha uye kushomeka kwekudzivirira, uye kusakanganisa kubatana nekuoma kwesimende. Polycarboxylic acid yakakwira-inoshanda mvura inoderedza inosiyana zvachose kubva naphthalene sulfonate formaldehyde condensate NSF uye melamine sulfonate formaldehyde condensate MSF mvura inoderedza. Inogona kuita kuti kongiri yedhaka ive yakakwira fluidity kunyangwe yakaderera dosage, uye ine yakaderera viscosity uye slump retention performance pane yakaderera mvura-simende ratio. Iine kuwirirana kuri nani nemasimende akasiyana uye chinhu chakakosha kune yakakwirira-simba uye yakakwirira-fluidity dhaka kongiri.

Polycarboxylate Superplasticizer ndicho chizvarwa chechitatu chepamusoro-chinoita chemakemikari mvura inoderedza yakagadziriswa mushure mehuni calcium uye naphthalene mvura inoderedza. Kuenzaniswa neyechinyakare mvura inoderedza, ine zvinotevera zvakanakira:

a. Yepamusoro yekudzikisa mvura mwero: Mwero wekudzikisa mvura yepolycarboxylic acid yakakwira-inoshanda mvura inoderedza inogona kusvika 25-40%.

b. Yakakwira simba rekukura mwero: yakanyanya kukura simba rekukura, kunyanya yakakwira yekutanga simba rekukura.

c. Yakanakisa slump kuchengetedza: Yakanakisa slump kuchengetedza kuita inogona kuona kushoma nguva kurasikirwa kwekongiri.

d. Yakanaka homogeneity: Kongiri yakagadziridzwa ine fluidity yakanaka kwazvo, iri nyore kudurura uye compact, uye inokodzera kuzvimiririra uye kuzvigadzirisa kongiri.

e. Production controllability: Mwero wekudzikisa mvura, kuchengetwa kwepurasitiki uye kuita kwemhepo kupinza kweiyi nhevedzano yezvidzikisiri zvemvura zvinogona kugadziriswa nekugadzirisa uremu hwepolymer molecular, kureba, density uye mhando yemapoka emaketani epadivi.

f. Yakakura kuchinjika: Iine yakanaka dispersibility uye kuchengetwa kwepurasitiki kune akasiyana akachena silicon, general silicon, slag silicate simende uye akasiyana admixtures kugadzira kongiri.

g. Yakaderera shrinkage: Inogona kunyatso kuvandudza vhoriyamu kugadzikana kwekongiri, uye iyo 28d shrinkage yenaphthalene-yakavakirwa mvura inoderedza kongiri inoderedzwa neanenge 20%, iyo inonyatso kudzikisa kukuvadzwa kunokonzerwa nekongiri kuputika.

h. Yakasvibira uye inoshamwaridzana nemamiriro ekunze: isiri-chepfu, isina-corrosive, uye haina formaldehyde uye zvimwe zvinokuvadza zvinoriumba.
