Cawv Tseem Ceeb Ntawm Polycarboxylic Acid Superplasticizer Muaj Txawv Rau Ntawm Txhua Tus

Cawv yam tseem ceeb ntawm polycarboxylic acid superplasticizer muaj kev txhawj xeeb los ntawm txhua tus

Cement thiab dej txo tus neeg sawv cev yog qhov tseem ceeb ntawm kev npaj-ua tiav pob zeb ua.

Tam sim no, cov khoom siv raw siv nyob rau hauv Suav teb' s xis mas cov khoom lag luam muaj ntau yam khoom siv thiab ntau yam hauv qhov muaj tseeb. Hauv kev txhim kho polycarboxylic acid dej tsim tawm rau ntau dua 30 xyoo, qhov rhiab ntawm lawv cov kev cuam tshuam tau ib txwm cuam tshuam rau cov neeg tsim khoom thiab cov neeg siv ntawm cov khoom.

Cov teeb meem yoog raws tau tsim kev kub ntxhov rau cov tub txawg feem ntau los ntawm lub sijhawm, ua rau" hlub" thiab" ntxub" polycarboxylate lub tshuab ua kua dej. Dab tsi yog qhov tseem ceeb uas cuam tshuam rau kev yoog raws ntawm polycarboxylic acid dej reducer thiab cement rau cement yam ntxwv? Txhawm rau ua kom cov phooj ywg to taub zoo dua, cov hauv qab no rau koj los ua cov lus qhia yooj yim.

Cov txheej txheem rau kev ua khoom siv Cement thiab cov khoom siv hauv kev tsim tawm kuj sib txawv. Yog li no, txawm hais tias kev ua cov khoom zoo ib yam thiab qib ntawm cov cement, nws cov ntxhia muaj pes tsawg, zoo nkauj, qhov loj me faib thiab lwm cov yam ntxwv yuav txawv heev, yog li poly carboxylic acid superplasticizer nyuaj rau kev ua si rau tib lub luag haujlwm, uas yog , poly carboxylic acid superplasticizer thiab cement ntawm qhov teeb meem adaptable. Dab tsi yog yam cuam tshuam rau cov kua roj polycarboxylic acid superplasticizer?

Lub hauv paus ntsiab lus cuam tshuam rau kev ua tau zoo ntawm polycarboxylic acid superplasticizer xis mas feem ntau 6 cov ntsiab lus:

(1) Cov ntxhia ua ke ntawm cov cement clinker;

(2) daim ntawv thiab qhov ntau thiab tsawg ntawm gypsum;

(3) xis mas;

(4) tus naj npawb thiab hom ntawm cov khoom sib xyaw hauv cov cement;

(5) cov alkali ntsiab lus hauv cov cement;

Maas cia lub sijhawm (freshness) thiab kub.

Qhov cuam tshuam ntawm cov ntaub ntawv raw ntawm cov nyhuv ntawm polycarboxylic acid superplasticizer.

Slag hmoov thiab ya tshauv.

Slag hmoov thiab ya cov hmoov tshauv yog ob qhov feem ntau cov khoom siv ntxhia hauv pob zeb hauv av qhob. Cov kev tshawb fawb qhia tau tias ib nrab hloov ntawm cov cement nrog slag hmoov thiab zoo siab ya tshauv tuaj yeem txhim kho cov nyhuv ntawm polycarboxylic acid dej txo, uas yog qhov tseem ceeb vim yog ob qho laj thawj:

(1) Txhaws nyhuv ntawm yoov tshauv thiab slag hmoov yog micro-sib sau ua ke.

(2) adsorption muaj peev xwm zoo yoov hmoov tshauv thiab slag hmoov rau polycarboxylic acid dej tso kua dej yog qhov me me.
