Hmoov polycarboxylate dej reducer
Cov khoom no yog tsim rau kev siv cov kua polycarboxylate superplasticizer tom qab nws tau teeb tsa ua kua. Nws yog tsim rau kev npaj-sib xyaw thiab cam khwb cia-hauv-qhov chaw pob zeb hauv ntau lub tsev lag luam thiab pej xeem. Nws kuj tseem tsim nyog rau kev ua haujlwm siab, kev ua haujlwm siab, kev ua haujlwm siab, super-kua, tsis muaj kev vibration, nws tus kheej-leveling, nws tus kheej-compacting thiab steel fiber tshwj xeeb pob zeb; precast pob zeb, kev thauj mus los ntev pob zeb, kev lag luam pob zeb, thiab lwm yam.
Nws yog tshwj xeeb tshaj yog tsim rau cov chaw tsim kho nyob rau hauv tej thaj chaw deb uas tsis haum rau lub tsev factories, thiab tsuas yog cov khoom sib xyaw yooj yim tuaj yeem ua tau raws li kev tsim kho.
Cov khoom no yog cov hmoov polycarboxylate dej txo tus neeg sawv cev nrog cov dej txo qis thiab siab slump tuav hom tsim los ntawm peb lub tuam txhab. Ntxiv nrog rau cov yam ntxwv tseem ceeb ntawm cov hmoov dej txo tus neeg sawv cev, nws qhov txiaj ntsig loj tshaj plaws yog tias nws muaj kev tuav pov hwm zoo heev. Nws tuaj yeem yaj ncaj qha nrog dej los npaj cov kua dej txo tus neeg sawv cev, thiab txhua qhov kev ua tau zoo tuaj yeem ncav cuag qhov kev ua tau zoo ntawm cov kua polycarboxylic acid twj tso kua mis, uas ua rau nws yooj yim heev nyob rau hauv daim ntawv thov txheej txheem. Nws tuaj yeem siv rau hauv thaj chaw deb kom ua tiav cov kev xav tau ntawm kev tsim kho sai ntawm cov nroj tsuag los ntawm kev nplawm thiab dissolving. Cov khoom lag luam muaj cov yam ntxwv ntawm cov khoom sib xws, cov ntsiab lus dej tsawg, zoo solubility, txo cov dej siab thiab siab slump tuav.
Tus nqi txo cov dej siab: cov dej txo qis tuaj yeem ncav cuag ntau dua 25 feem pua, thiab cov dej ntws tuaj yeem txhim kho tau zoo nyob rau hauv cov xwm txheej ntawm tib cov dej ntxiv rau cov pob zeb;
Kev khaws cia siab: cov tshuaj polycarboxylate hmoov dej reducer yuav ua rau qee yam kev puas tsuaj rau ntau dua lossis tsawg dua carboxylic acid pawg vim qhov kub thiab txias hauv cov txheej txheem ziab. Yog li ntawd, qhov slump tuav kev ua tau zoo tom qab cov kua hloov mus rau hauv cov khoom yog txo qis heev. SP-409 yog tsim los ntawm cov txheej txheem tshwj xeeb, kom cov pawg carboxylic acid tsis raug puas tsuaj thaum lub sij hawm tsim cov hmoov, kom cov slump khaws cia ntawm cov kua txiv cawv qub.
Zoo solubility thiab ceev dissolution tus nqi: vim nws cov yam ntxwv particle loj thiab loj tshwj xeeb deg cheeb tsam. Yog li ntawd, nws tuaj yeem yaj sai sai hauv cov txheej txheem ntawm cov dej dissolution. Thiab tsis muaj qhov pom tseeb impurities tom qab dissolution.
Qhov pom zoo noj ntau npaum li cas ntawm cov hmoov qhuav qhuav yog {{0}}.2 rau 0.3 feem pua ntawm cov khoom siv cementitious. Tom qab dissolving, nws tuaj yeem siv los hloov cov kua polycarboxylate dej reducer, thiab nws tuaj yeem hloov pauv raws li cov ntsiab lus tseeb tom qab dissolving.

Ntim thiab khaws cia
Cov khoom no yog 25 Kg / hnab hauv airtight ntim. Raws li cov neeg siv khoom xav tau, lub hnab ntim loj lossis ntim tshwj xeeb tuaj yeem muab tau.
Cov khoom no yuav tsum tau thauj thiab khaws cia rau hauv qhov chaw qhuav ntawm chav tsev kub (hauv qab 40 degree), tsis txhob tshav ntuj ncaj qha. Tsis txhob sib tsoo lossis nias hnyav kom tsis txhob cuam tshuam cov khoom.
Cov khoom no muaj lub neej txee ntawm 12 lub hlis nyob rau hauv thawj ntim thiab yuav tsum tau siv nyob rau hauv 60 hnub tom qab qhib.
