Lub hauv paus ntsiab lus ntawm cementing admixtures tsuas yog suav nrog cov hauv qab no:
Mechanism ntawm Kev Ua: Centesing Admixtures ncua qhov pib coagulation ntawm kev ua kom zoo nkauj ntawm kev ua tiav, yog li kho qhov ua tau zoo ntawm Maas slurry. Piv txwv li, organic surfactant retarders ncua lub sij hawm teeb tsa lub sij hawm ntawm cement los ntawm cov txheej txheem no.
Tshuaj lom neeg muaj feem: cementing admixtures tuaj yeem faib ua polymers, surfactants thiab inorganic ntsev. Cov tshuaj lom neeg no tuaj yeem txhim kho kev ua tau zoo ntawm cov kua dej lossis cov maj mam slurry thiab ua tau raws li kev cai ntawm kev tsim khoom. Piv txwv li, polymer admixtures nce cov viscosity ntawm kev txhim kho cov ntsiab lus ntawm cov ntsiab lus ntawm kev ua kom zoo nkauj los ntawm kev hloov kho ion concecting ntawm kev daws teeb meem.
Daim Ntawv Thov Qhuab Qhia: Cementing AdmixTures yog siv dav hauv cov khoom ua kom cov roj caasing ntawm cov roj thiab roj thiab dej kom zoo. Hauv kev ua kom cov roj thiab roj zoo, cov roj zoo, tau siv los txhim kho cov kev ruaj ntseg thiab lub zog ntawm cov roj av, tiv thaiv roj, roj av los ntawm kev nqis tes, thiab txhim kho kev siv hluav taws xob. Hauv dej zoo cementing, admixtures yog siv los tswj lub sij hawm hloov pauv ntawm cov xis, thiab ua kom lub sijhawm siv cov dej kom ntev. 2. Hom tshwj xeeb: cov cementing admixtas, cov neeg organic, thiab cov organic ua kom nrawm nrawm nrawm nrawm nrawm thiab cov nyhuv ntsev. Dispersants xws li livin sulfonates thiab lawv cov derivatives tau siv los txhim kho cov rheology thiab raug ncua kev kawm tau ntawm cov cement slurry. Thickeners nce cov viscosity thiab shear fort ntawm drilling kua los ntawm nce cov ntsiab lus ntawm cov tshuaj polymer.
