Feem Tseem Ceeb - Yasizer Vs Superplasticizer
Mar 23, 2020
Plasticizers, raws li sawv cev los ntawm lub npe, yog cov khoom siv tshuaj uas tau ntxiv rau cov tshuaj ntxiv los ua kom cov yas ntawm cov ntawd.
Ua kom cov yas dhau yog sib npaug rau kev ua kom cov quav muag. Nws ua rau cov tshuaj hloov pauv thiab ruaj khov. Cov Kws Tshaj Lij Khoom Siv yog cov polymers uas tau siv los tiv thaiv cov khoom tawg yooj yim ntawm kev ncua ntawv. Ob leeg plasticizers thiab Superplasticizers paub zoo li dispersants. Ib qho tawg yog qhov sib xyaw ua tshuaj lom neeg uas ntxiv rau hauv kev ncua ua kom txhim kho kev sib cais ntawm cov ntawv. Ob qhov sib txuas no yog siv los ua kev ntxiv rau cov pob zeb ua ke kom txo cov dej qhov xav tau rau cov pob zeb sib tov sib xyaw. Yog li ntawd, cov yas tsim hluav taws xob thiab cov neeg lim dej kom sib txawv nyias muaj nyias raws li kev txo qis ntawm cov dej xav tau rau cov pob zeb ua kev sib tov. Lub ntsiab sib txawv ntawm cov yas thiab cov superplasticizers yog tias cov yas tsim hluav taws xob tuaj yeem txo qhov xav tau dej los ntawm 5-15% hos cov superplasticizers tuaj yeem txo qhov xav tau dej ntawm 30%.
