Txoj Kev Npaj Polycarboxylate Superplasticizer Synthesized Ntawm Chav Kub:
Lub invention muaj feem xyuam rau lub technical field ntawm lub tsev cov khoom admixtures thiab tshwj xeeb tshaj yog muaj feem xyuam rau ib tug polycarboxylate superplasticizer synthesized nyob rau hauv chav tsev kub thiab ib tug npaj txoj kev.Txoj kev npaj muaj xws li cov kauj ruam hauv qab no: ntxiv unsaturated polyether methyl allyl polyoxyethylene ether, hydrogen peroxide thiab 2-acrylamide tetradecyl sulfonic acid rau hauv dej deionized los npaj cov tshuaj hauv paus;Dripping ib qho kev daws teeb meem A uas muaj acrylic acid, methacrylic acid thiab ib tug saw hloov mus rau mercaptoacetic acid thiab ib tug aqueous tov ntawm vitamin C, stirring uniformly, nqa tawm ib tug dawb radical polymerization cov tshuaj tiv thaiv nyob rau hauv chav tsev kub, thiab regulating pH nqi ntawm cov tshuaj tiv thaiv system. yuav tsum yog 6-7 los ntawm kev siv kua caustic soda tom qab cov tshuaj tiv thaiv tas, yog li tau txais cov polycarboxylate superplasticizer.Lub polycarboxylate superplasticizer tau los ntawm kev tsim khoom tuaj yeem tswj tau qhov sib txawv ntawm lub sijhawm ntev, muaj cov saw ntev ntev, zoo nyob rau hauv kev ruaj ntseg dispersion, yooj yim hauv cov txheej txheem kev npaj thiab tsis tshua muaj zog noj, tuaj yeem ua ke ntawm chav tsev kub thiab muaj txiaj ntsig zoo nyiaj txiag.
Motar Performance:
1. Nws yog homologous ntawm cov dej-txo tus nqi ntawm motar thiab fluidity ntawm cement paste.Qhov ntau fluidity ntawm cement paste, qhov ntau dua dej-txo tus nqi ntawm motar.
2. Dej-txo tus nqi nce ceev thiab siab thaum qhov ntau npaum li cas.Thaum cov koob tshuaj zoo ib yam, cov dej-txo tus nqi ntawm PCE hmoov yog 35% siab dua li ntawm lwm cov superplasticizer hauv khw.
3. Vim muaj kev cuam tshuam los ntawm kev sib xyaw thiab xuab zeb coarse aggregate, Dej-txo tus nqi hauv pob zeb yog txawv ntawm cov motar.Thaum lub admixture thiab xuab zeb coarse aggregate yog nyob rau hauv kev pom zoo ntawm cov pob zeb ntws, cov dej-txo tus nqi ntawm cov pob zeb yog siab dua li ntawm motar.
4. Nws muaj antifreezing kev ua tau zoo thaum kub siab tshaj -5ºC.Yog li nws tuaj yeem siv tau rau hauv cov pob zeb antifreezing.
Polycarboxylate Superplasticizer Khoom nta:
1. Tus nqi txo dej siab: nws tuaj yeem ua kom cov dej txo qis mus txog ntau dua 25%, thiab txhim kho cov dej ntws zoo heev
nyob rau hauv cov xwm txheej ntawm tib tus nqi ntawm cov dej ntxiv rau cov pob zeb;
2. siab slump tsis kam: nyob rau hauv cov txheej txheem tshuaj tsuag kom qhuav, pawg carboxylic yuav ua rau muaj kev puas tsuaj ntau dua los yog tsawg dua.
ib txwm polycarboxylate superplasticizer.Yog li kom txo tau qhov poob qis ntawm kev tuav pov hwm zoo tom qab cov kua
ransformed rau hauv cov khoom.Sp-409 yog tsim los ntawm cov txheej txheem tshwj xeeb, kom cov pawg carboxylic acid tsis puas
nyob rau hauv cov hmoov manufacturing txheej txheem, thiaj li yuav khaws cov slump retention ntawm tus thawj kua niam cawv.
3. Zoo solubility thiab ceev ceev dissolution tus nqi: vim nws cov yam tsis xws luag thiab loj tshwj xeeb deg cheeb tsam.Yog li ntawd, nws ua tau
yuav yaj sai sai nyob rau hauv tus txheej txheem ntawm dej dissolution.Thiab tsis muaj qhov pom tseeb impurities tom qab dissolution.
Scope ntawm daim ntawv thov:
1. Haum rau kev tsim kho nyob deb li cas hom twj tso kua mis.
2. Haum rau kev sib xyaw ua ke ib txwm ua pob zeb, ua kom muaj kev ua haujlwm siab, cov pob zeb ua kom muaj zog thiab ultra-siab zog pob zeb.
3. Haum rau impervious, antifreezed thiab siab durability qhob.
4. Haum rau kev ua haujlwm siab thiab siab ntws pob zeb, nws tus kheej-leveling pob zeb, ncaj ntsej muag pob zeb thiab SCC (tus kheej compact qhob).
5. Haum rau ntau npaum li cas cov ntxhia hmoov hom pob zeb.
6. Haum rau cov pob zeb loj uas siv hauv kev nthuav dav, railway, choj, qhov, dej txuag dej, chaw nres nkoj, wharf, hauv av thiab lwm yam.
Kev nyab xeeb thiab ceev faj:
1. Cov khoom no yog alkalescence khoom tsis muaj tshuaj lom, corrosiveness thiab muaj kuab paug.
Nws yog unedible thaum nws tuaj rau lub cev thiab qhov muag, thov ntxuav nws hauv dej huv.Thaum muaj kev tsis haum rau qee lub cev, thov xa tus neeg mus rau tsev kho mob sai sai.
2. Cov khoom no yog khaws cia rau hauv daim ntawv thawv nrog PE hnab sab hauv.Tsis txhob nag thiab sundries sib tov.
3. Lub sijhawm lav zoo yog 12 lub hlis.
