Lub teeb pob zeb Additives | High-Performance Foaming Agents rau Cellular Concrete
Lub superplasticizer yog ib yam khoom ntxiv rau cov khoom lossis cov khoom siv los ua kom nws cov plasticity. Nws tuaj yeem txo cov ntsiab lus dej thiab ua kom cov khoom muag muag. Nws tseem tuaj yeem ua rau kom muaj zog thiab ruaj khov ntawm cov khoom.
Superplasticizers yog siv los ua ib qho khoom siv los txhim kho qhov zoo thiab ruaj khov ntawm pob zeb. Lawv tuaj yeem pab txhim kho cov flowability ntawm pob zeb, tiv thaiv kev sib cais ntawm cov khoom hauv ib qho kev ncua, thiab ncua kev teeb tsa ntawm cov cement. Lawv kuj tuaj yeem pab txo cov permeability ntawm pob zeb.
Qee cov superplasticizers yog hluavtaws thiab qee qhov yog ntuj. Lawv feem ntau ua raws li lignosulphonate. Cov molecules ntawm ib tug superplasticizer yog ntau pua lub sij hawm loj dua cov molecule ntawm dej.
Lawv feem ntau yog siv los txo tus nqi ntawm cov dej uas xav tau hauv kev sib xyaw ua ke. Lawv tuaj yeem txo cov dej-rau-cement piv, uas tuaj yeem ua kom muaj zog thiab kav ntev ntawm cov pob zeb. Lawv kuj tuaj yeem txo qhov shrinkage ntawm cov pob zeb thiab tuaj yeem ua kom cov txheej txheem hydration. Lawv kuj tuaj yeem pab tswj qhov kub ntawm cov pob zeb hauv cov ntim loj.
Lawv kuj feem ntau siv los ua ib qho kev pabcuam hauv plasters, tshuaj pleev ib ce, thiab cov tshuaj ntxuav. Lawv feem ntau ntxiv rau cement ntawm txog 0.5-0.3% ntawm qhov hnyav ntawm cov cement. Lawv kuj tau siv los ua ib qho kev pabcuam hauv kev tsim cov khoom yas.
Qhov ntau npaum li cas ntawm lub plasticizer yog txiav txim los ntawm Marsh Cone Test. Nws tuaj yeem sib txawv ntawm tsib mus rau nees nkaum litres ntawm plasticizer ib cubic meter ntawm pob zeb. Nws feem ntau yog tov thaum lub sij hawm sib tov thiab thaum lub sij hawm lub site ncuav.
