Polycarboxylate superplasticizeryog suav hais tias yog ib qho kev ua tau zoo heev. Tib neeg ib txwm cia siab tias yuav muaj kev nyab xeeb dua, yooj yim dua, ua haujlwm tau zoo, thiab hloov tau ntau dua li cov tshuaj naphthalene ib txwm siv hauv cov ntawv thov, tab sis qhov tseeb tsis yog qhov teeb meem. tab tom ntsib teeb meem sib txawv. Yog li, dab tsi yog qhov ceev faj rau kev sivpolycarboxylic acidcov khoom xyaw?
1. Polycarboxylate superplasticizeryuav tsum tswj cov dej kom tsim nyog. Ntawm qhov tod tes, txhawm rau kom ntseeg tau tias dej-binder ratio, ntawm qhov tod tes, vimpolycarboxylate superplasticizeryog rhiab heev rau kev siv dej. Cov ntsuas uas feem ntau cuam tshuam txog kev ua tau zoo ntawm cov pob zeb sib tov muaj xws li fluidity, cohesion thiab dej tuav. Vimpolycarboxylate superplasticizerNws yog rhiab heev rau kev siv dej, qee zaum cov dej haus tsuas yog nce los ntawm 1kg ~ 3kg thaum lub sijhawm sim thiab tsim khoom. Los ntshav hnyav, pawg ntawm cov pob zeb raug, rub hauv qab los ntawm lev, thiab lwm yam, tsis tuaj yeem lav qhov sib xws ntawm cov pob zeb sib xyaw. Yog li ntawd, kev siv dej unilateral yuav tsum tau tswj nruj me ntsis thaum lub sijhawm tsim khoom.
2. Tswj cov ntsiab lus ntawmpolycarboxylic acid. Cov ntsiab lus tsis txaus ntawm pob zeb yog tshwm sim los ntawm kev poob qis, poob loj, thiab dej tsis zoo; ntau dhau yuav ua rau mob hnyav, kev sib cais, thiab kev rub hauv qab. Nws yog ib qho tsim nyog yuav tau ua ntau yam kev ntsuam xyuas los txiav txim qhov zoo tshaj plaws haum ntawm kev siv dej thiabpolycarboxylate superplasticizercov ntsiab lus. Point, uas yog, qhov zoo tshaj plaws kev siv dej thiab kev siv tshuaj ntxiv.
3. Nws yog nruj me ntsis txwv tsis pub sib tov naphthalene admixtures. Raws li cov haujlwm sib txawv, feem ntau cov pob zeb sib xyaw yuav tsum siv naphthalene admixtures thaum sivpce ua. Yog tias muaj kev tso cai, nws yog qhov zoo tshaj plaws los siv hauv cov chaw sib cais. Yog tib lub tsev muaj ob qho tib sipolycarboxylate superplasticizerthiab naphthalene, lub thawv hnyav, cov raj xa dej thiab cov khoom sib tov rau cov khoom sib tov yuav tsum tau muab ntxuav kom huv si thaum siv lwm yam, thiab cov pob zeb ua pob zeb yuav tsum tau muab ntxuav kom huv. Ntxuav thiab rov ua dua. Yogpolycarboxylic acidthiab naphthalene-raws li admixtures yog tov thiab siv, ob admixtures yuav hnov mob ua kom cov pob zeb "ceev ceev", ua rau tag nrho lub tsheb yuav tsum tau scrapped.
4.Txhim kho qhov kev tshuaj xyuas ntawmpolycarboxylate superplasticizercov khoom xyaw. Thaum kuaj xyuas cov khoom sib xyaw, coj mus kuaj los ntawm cov khoom siv raw uas twb muaj lawm uas yuav raug siv, thiab sim cov pob zeb ua raws li cov kev xav tau ntawm qhov project. Yog tias pom muaj teeb meem, thov tam sim ntawd nug cov neeg ua haujlwm ntawm cov chaw tsim khoom sib xyaw kom hloov kho.
Hauv luv, pob zebpolycarboxylic acid admixtureyog ib yam khoom tshiab. Piv nrog rau cov tshuaj txo cov dej ib txwm muaj, nws tsis tsuas yog muaj cov tshuaj me me xwb, cov dej txo qis, cov tshuaj chlorine tsawg thiab cov alkalinity tsawg, thiab cov txiaj ntsig zoo ntawm kev tuav pov hwm. Txhim kho lub durability ntawm qhob qauv, thiab cov txheej txheem ntau lawm ntawmpolycarboxylate superplasticizerdej reducer yog huv si thiab tsis muaj kuab paug. Nws yog ib hom tshiab ntawm ntsuab thiab ib puag ncig tus phooj ywg ua haujlwm siab dej reducer.
