Lub tshuab tseem ceeb ntawm daim ntawv thov ntawm polycarboxylate superplasticizer
Nyob rau hauv xyoo tas los no, polycarboxylate superplasticizers tau siv dav hauv ntau qhov kev tsim kho hauv kuv lub tebchaws. Cov pob zeb niaj hnub no muaj cov kev xav tau siab rau kev ua haujlwm ntxiv, yog li thaum polycarboxylate superplasticizer ntxiv rau cov pob zeb ua ke, cov thev naus laus zis hauv qab no yuav tsum tau xav txog.
(1) Compatibility technology ntawm polycarboxylate system. Vim yog cov qauv tshwj xeeb ntawm polycarboxylate high-performance water reducer, nws tsis tuaj yeem khaws cia thiab siv ua ke nrog lwm cov dej reducers, tshwj xeeb tshaj yog cov naphthalene-based water reducer. Thaum nws yuav tsum tau siv hloov pauv nrog ntau hom dej txo cov neeg ua haujlwm, cov ntim khoom tsim nyog yuav tsum tau ua tib zoo ntxuav kom tsis txhob muaj kab mob sib kis los ntawm kev cuam tshuam qhov zoo ntawm cov pob zeb. Lub adsorption kev ua tau zoo ntawm superplasticizer sib txawv nrog ntau hom cement. Txij li thaum lub compatibility ntau ntawm polycarboxylate superplasticizers nyob rau hauv cov cement yog qhov nqaim, kev sib raug zoo tsis zoo yog yam tsis muaj kev zam. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom nws ntau npaum li cas los yog siv ntau hom cement. kom daws tau qhov teeb meem no zoo.
⑵ Polycarboxylate superplasticizer retarding tshuab. Nyob rau hauv txoj kev tsim kho, vim lub sij hawm luv luv retarding, kev siv cov retarders tuaj yeem ua kom ntev lub plasticity ntawm pob zeb. Txawm li cas los xij, qhov tsis sib haum xeeb ntawm ob qho tib si yuav tsum tau txiav txim siab kom tsis txhob txo qis ntawm kev ua tau zoo.
⑶ tswj cov ntsiab lus roj. Polycarboxylate dej reducer muaj qhov zoo ntawm huab cua nkag thiab tuaj yeem siv ua ke nrog defoamers thiab air-entraining agents. Los ntawm kev tshem tawm thawj zaug thiab tom qab ntawd qhia, cov ntsiab lus huab cua ntawm cov pob zeb tuaj yeem tswj tau, thiab nws txoj haujlwm ua haujlwm tau zoo tuaj yeem txhim kho.
⑷ Tswj cov av nkos hauv cov xuab zeb thiab pob zeb. Cov av nkos ntawm cov xuab zeb thiab pob zeb tseem yuav cuam tshuam rau daim ntawv thov cov nyhuv ntawm polycarboxylate cov dej ua haujlwm siab. Yog tias cov av nkos hauv cov xuab zeb ntau tshaj 2 feem pua, cov qauv ntawm cov av nplaum yuav nqus tau cov dej ntau ntawm cov tshuaj tiv thaiv molecules, uas yuav txo qis kev ua haujlwm ntawm cov pob zeb. Yog tias cov av nkos hauv cov txheej txheem tsim kho yog qhov loj, koj yuav tsum xav txog kev xaiv cov av nplaum-resistant polycarboxylate superplasticizer.
