(1) cawv rau ntawm pob zeb sib xyaw

Tus neeg saib xyuas lub sijhawm thaum ntxov muaj zog tuaj yeem ua kom lub sijhawm ua kom luv, tab sis thaum cov ntsiab lus ntawm Trical ntawm cov xis nyob lossis qis dua gypsum, sulfate yuav ncua sij hawm lub sij hawm cement. Feem ntau, cov ntsiab lus cua hauv cov pob zeb yuav tsis nce los ntawm thaum ntxov lub zog admixture yog txiav txim siab los ntawm huab cua cov ntsiab lus ntawm dej-txo admixture. Piv txwv li, cov ntsiab lus roj yuav tsis nce ntxiv thaum compounded nrog calcium qab zib dej reducer, tab sis yuav nce thaum compound nrog calcium Ntoo Dej Reducer.

(2) cuam tshuam rau cov pob zeb

Cov neeg sawv cev ntxov muaj zog tuaj yeem txhim kho nws lub zog thaum ntxov; Cov kev txhim kho degree ntawm tib lub zog thaum ntxov muaj lub zog thaum ntxov, kev kho mob, dej xis thiab cement hom. Qhov cuam tshuam rau lub zog ntev ntawm cov pob zeb ua yog tsis sib xws, nrog siab thiab qis. Kev siv zog thaum ntxov muaj qhov cuam tshuam zoo ntawm kev siv tshuaj, tab sis thaum cov tshuaj muaj kev tsis zoo rau lub zog tom qab thiab lub zog tsis zoo. Cov neeg sawv cev dej ntxov-txo cov dej tsis muaj zog, thiab nws ua tau zoo dua li tias thaum ntxov muaj zog tus neeg sawv cev, uas tuaj yeem tswj hwm qhov hloov pauv ntawm lub zog lig. Triethanine tuaj yeem txhawb cov lub zog thaum ntxov ntawm cov cement. Nws tuaj yeem ua kom nrawm cov hydration ntawm tricalcium aluminate, tab sis ncua cov hydration ntawm trycium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate thiab dicalcium silicate Yog tias cov ntsiab lus tseem siab dhau, lub zog ntawm cov pob zeb yuav raug txo kom tsawg.

Cov neeg sawv cev ntxov lub zog tsis muaj qhov cuam tshuam rau kev ua haujlwm ntawm cov tshuaj tiv thaiv kab mob hauv ions, uas yuav txhawb kev txhim kho kev txhim kho kev txhim kho hauv kev txhim kho hauv kev txhim kho hauv kev txhim kho hauv kev txhim kho hauv kev txhim kho hauv kev txhim kho. Thaum cov tshuaj yog loj, tshuaj lom neeg corrosion, hnav tsis kam thiab khov tsis kam kuj tseem yuav raug txo. Rau kev ua vaj tse, txo lub zog ntawm cov pob zeb ua kom zoo thiab nce cov pob zeb thaum ntxov muaj cov kev cuam tshuam me ntsis ntawm cov theem tom qab pob zeb. Tam sim no, kev siv chloride-muaj additives tau txwv tsis pub muaj nyob rau hauv tus qauv hauv lub teb chaws tshiab. Txhawm rau tiv thaiv cov nyhuv ntawm chloride ntsev rau kev txhawb zog corrosion, xeb inhibitor thiab chloride ntsev yog feem ntau siv ua ke.

Thaum siv sulfate tus neeg sawv cev ntxov lub zog, nws yuav ua rau Alkalinity ntawm cov khoom siv ua kua, nws yuav txhawb nqa cov tshuaj lom neeg ntawm Alkali, thiab ua rau cov pob zeb ua kom puas vim Alkali nthuav.
