Qhov sib txawv ntawm cov dej reducer thiab superplasticizer
Superplasticizers thiab plasticizers yog ob qho tib si additives uas siv los txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm pob zeb. Txawm li cas los xij, muaj qee qhov sib txawv tseem ceeb ntawm ob.
Superplasticizers, tseem hu ua high-range water reducers los yog HRWR, yog cov tshuaj additives uas yog siv los txhim kho cov flowability ntawm pob zeb tsis txo nws lub zog. Lawv feem ntau yog siv rau hauv kev sib xyaw ua ke lossis precast qhob uas yuav tsum muaj kev ua haujlwm siab. Superplasticizers muaj txiaj ntsig zoo ntawm kev sib cais cov cement, uas tso cai rau txo qis hauv dej cov ntsiab lus thaum tswj kev ua haujlwm yuav tsum tau ua. Qhov no tuaj yeem ua rau cov pob zeb muaj zog thiab ruaj khov dua nrog cov kab nrib pleb tsawg dua thiab siab dua tiv thaiv te thiab puas.
Plasticizers, ntawm qhov tod tes, kuj yog cov tshuaj ntxiv siv los txhim kho kev ua haujlwm ntawm cov pob zeb, tab sis lawv tsis muab tib theem ntawm kev txo cov dej hauv cov ntsiab lus xws li superplasticizers. Lawv ua haujlwm los ntawm kev txo qhov nro ntawm cov dej hauv qhov sib tov, uas txhim kho cov plasticity thiab flowability ntawm cov cement paste. Plasticizers feem ntau yog siv rau hauv cov pob zeb uas muaj zog qis los yog qhov yuav tsum tau ua haujlwm nruab nrab.
Hauv cov ntsiab lus, superplasticizers muab cov txiaj ntsig tseem ceeb ntawm lub zog, ua haujlwm ntev, thiab ua haujlwm tau zoo, thaum cov plasticizers feem ntau yog siv rau cov kev xav tau tsawg dua.
