Daim ntawv thov teb ntawm polycarboxylate superplasticizer

Polycarboxylate superplasticizer yog ib yam tshiab ntawm cov pob zeb sib xyaw, uas tuaj yeem txo cov cement hauv pob zeb, txhim kho cov dej ntws thiab cov twj tso kua mis ntawm cov pob zeb, txo cov pob zeb thiab cov pob zeb tawg, thiab txhim kho cov kav ntev thiab huab cua tiv thaiv ntawm pob zeb. Vim nws qhov kev ua tau zoo heev, polycarboxylate superplasticizer tau siv dav hauv cov khoom siv hauv tsev. Nws cov cheeb tsam kev thov tseem ceeb suav nrog cov hauv qab no:

1. Kev tsim vaj tsev pob zeb: polycarboxylate superplasticizer tuaj yeem txhim kho qhov fluidity ntawm pob zeb, ua pob zeb yooj yim rau kev tsim thiab txheej txheem, thiab qhov zoo ntawm qhov chaw zoo dua. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txo qhov shrinkage thiab tawg ntawm pob zeb, thiab txhim kho cov kav ntev thiab huab cua tsis kam ntawm pob zeb.

2. Txoj kev engineering: Nyob rau hauv cov txheej txheem ntawm kev tsim kho, polycarboxylate superplasticizer tuaj yeem txhawb nqa cov dej ntawm cov cement thiab txhim kho lub zog thiab ruaj khov ntawm pob zeb. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txhim kho cov kav ntev thiab huab cua tiv thaiv ntawm cov pob zeb, ua rau txoj kev ruaj khov dua.
 

3. Choj engineering: Nyob rau hauv tus txheej txheem ntawm kev tsim choj, polycarboxylate superplasticizer tuaj yeem txhim kho cov dej ntws thiab cov twj tso kua mis ntawm cov pob zeb,

li no ua kom cov kev tsim kho efficiency ntawm pob zeb thiab txo lub sij hawm tsim kho. Tsis tas li ntawd, nws tuaj yeem txo qhov shrinkage thiab cracking ntawm pob zeb, txhim kho lub durability ntawm pob zeb, thiab txuas ntxiv lub neej kev pab cuam ntawm cov choj.

4. Cov dej txuag dej: polycarboxylate superplasticizers kuj tau siv dav hauv cov dej txuag dej, xws li dams, sluices, channels, thiab lwm yam. Nws tuaj yeem txhim kho qhov fluidity thiab impermeability ntawm pob zeb, ua kom cov dej txuag dej ruaj ntseg thiab txhim khu kev qha.

5. Kev tsim hluav taws xob hauv av: Hauv cov txheej txheem ntawm kev tsim kho hauv av, polycarboxylate superplasticizer tuaj yeem txhim kho cov dej ntws thiab cov twj tso kua mis ntawm cov pob zeb, txo cov pob zeb shrinkage thiab tawg, thiab xyuas kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm underground engineering.

Nyob rau hauv luv luv, polycarboxylate high-efficiency dej reducer muaj ntau yam kev siv, tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv hauv tsev, thiab tuaj yeem txhim kho kev tsim kho thiab kev tsim kho kom zoo. Nws yog ib qho tseem ceeb heev tshiab pob zeb admixture.
