Hauv qee qhov kev tsim ua vaj tse, tus neeg tsim khoom feem ntau ntxiv cov dej-txo tus neeg sawv cev, uas tuaj yeem tswj cov pob zeb poob qis, txhim kho qhov tawg ntawm cov pob zeb, thiab txo cov dej haus. Txawm li cas los xij, muaj qhov tsis zoo uas cov dej txo tus neeg sawv cev yog ib qho surfactant, uas yuav ua rau muaj kev ua npuas ncauj, uas yuav cuam tshuam rau lub zog thiab qhov zoo ntawm cov pob zeb. Yog tias ua npuas dej tau tsim thaum lub sijhawm tsim kho, nws yuav tsum tau muab tshem tawm hauv lub sijhawm. Muaj ib tug defoamer uas yuav ua tau heev Qhov zoo tshaj plaws txoj kev uas yuav tshem tawm cov pob zeb ua npuas ncauj yog cement dej txo tus neeg sawv cev defoamer.

Defoaming kev ua tau zoo ntawm cement dej txo tus neeg sawv cev defoamer:

Covdefoamer Feem ntau yog ua los ntawm kev hloov kho polyether thiab belongs rau polyetherdefoamer. Covdefoamer yuav tsis cuam tshuam rau cov khoom tseem ceeb ntawm cov pob zeb hauv daim ntawv thov ntawm pob zeb ua npuas ncauj, thiab tuaj yeem muaj qhov ruaj khov defoaming thiab ua npuas ncauj suppressing teebmeem. Covdefoamermuaj zoo dispersibility nyob rau hauv lub pob zeb ua npuas ncauj, thiab yuav sai sai dispersed mus rau hauv lub pob zeb ua npuas ncauj kom ua tiav qhov kawg ua npuas ncauj tawg thiab defoaming nyhuv. Ntxiv nrog rau de-foaming thiab anti-foaming hauv pob zeb ua npuas ncauj, nws tuaj yeem de-foam nyob rau hauv kub thiab muaj zog acid thiab alkali ib puag ncig.

Cov nyhuv defoaming ntawm cov cement dej txo tus neeg sawv cevdefoamer:

Cov nyhuv ntawm covdefoamer ntawm qhov kev ua tau zoo ntawm pob zeb yog qhov tshwm sim hauv ob qho tib si: ntawm ib sab, nws tuaj yeem tshem tawm cov npuas huab cua ntawm cov pob zeb thiab cov formwork rau qee yam, tiv thaiv los yog tshem tawm cov tiam ntawm honeycomb thiab pockmarked nto ntawm pob zeb nto, thiab ua rau saum npoo ntawm pob zeb muaj High flatness thiab gloss. Ntawm qhov tod tes, lubdefoamer tuaj yeem tshem tawm ntau cov pa npuas hauv cov pob zeb, txo cov cua cov ntsiab lus thiab cov porosity sab hauv ntawm cov pob zeb, thiab txhim kho cov khoom siv dag zog thiab ua haujlwm ntev ntawm cov pob zeb.

Yuav siv cov cement dej txo tus neeg sawv cev li casdefoamer:

1. Thaum lubdefoamer yog siv nyob rau hauv zus tau tej cov pob zeb ua npuas ncauj nrog ib tug dej txo tus neeg sawv cev, lub pob zeb ua npuas ncauj slurry yuav kuj nplaum. Nws yog pom zoo kom ntxiv covdefoamer sai sai thaum ua npuas ncauj tsim, uas tuaj yeem tshem tawm cov npuas loj tsis sib xws hauv cov pob zeb ua npuas ncauj thiab qhia txog kev sib xws Cov npuas me me tuaj yeem ua rau cov pob zeb ua kom tawv tawv.

2. Covdefoamer muaj zog dispersibility thiab yooj yim rau kev sib cais tom qab muab tso rau ib lub sij hawm ntev. Nws raug pom zoo tias kev sib xyaw tas li yuav tsum tau ua thaum lub sij hawm tshem tawm cov pob zeb ua npuas ncauj.

3. Covdefoamer tej zaum yuav degraded vim nws alkalinity, yog li thov tsis txhob siv nws thaum tus nqi pH siab dua 10.
