Fatty Acid Series Superplasticizer

Fatty acid series superplasticizer

--Los ntawm Baidu Encyclopedia

Lub npe tshuaj yog aliphatic hydroxysulfonate polymer, thiab cov ntaub ntawv raw uas tsim los yog acetone, formaldehyde, Na2SO3, Na2S2O5, catalyst, thiab lwm yam. Nws cov concentration yog 30 feem pua ​​~ 40 feem pua ​​ntawm cov khoom ua kua xim av-liab, cov dej yuav txo tau mus txog 20. feem pua, nws tuaj yeem siv rau cov pob zeb qis, thiab nws yuav stain lub pob zeb.

HSB (High Strence Bing) yog carbonyl pyroaldehyde synthesized los ntawm polymer sulfonation. Cov saw tseem ceeb ntawm lub hauv paus hydrophobic yog aliphatic hydrocarbons, tom qab ntawd hu ua HSB, uas yog ntsuab superplasticizer tsim los ntawm HS hauv Qingdao. Cov khoom no tsis ua phem rau ib puag ncig thiab tsis ua rau tib neeg noj qab haus huv. Kev siv dav rau cov cement, pom tseeb qhov cuam tshuam rau cov pob zeb, qhov poob qis me me, tsis muaj sodium sulfate crystallization ntawm qhov kub thiab txias, dav siv hauv kev npaj cov twj tso kua mis, retardation, lub zog thaum ntxov, antifreeze, cua nkag thiab lwm yam dej txo tus kheej. siv ua ke nrog naphthalene dej txo tus neeg saib xyuas, amino dej txo tus neeg saib xyuas thiab polycarboxylate dej txo tus neeg sawv cev.

Main Specifications

1. Appearance of brown-red liquid; 2. Solid content>35 feem pua; 3. Lub ntiajteb txawj nqus 1.15-1.2

Cov yam ntxwv ua haujlwm

1. Tus nqi txo dej siab. Qhov ntau npaum li cas yog 1-2 feem pua ​​, thiab tus nqi txo cov dej tuaj yeem ncav cuag 15-25 feem pua ​​. Raws li qhov xwm txheej ntawm tib lub zog poob qis, ntxiv HSB tuaj yeem txuag tau 25-30 feem pua ​​​​ntawm cov cement noj;

2. Thaum ntxov muaj zog thiab txhim kho cov nyhuv yog pom tseeb. Cov pob zeb sib xyaw nrog HSB tuaj yeem ncav cuag 60-70 feem pua ​​​​ntawm cov qauv tsim lub zog nyob rau hauv peb hnub, 100 feem pua ​​​​hauv xya hnub, thiab 30-40 feem pua ​​​​siab dua li cov pob zeb tsis muaj zog hauv 28 hnub;

3. Kev txuag yas siab. Kev poob ntawm cov pob zeb poob thaum lub sij hawm me me, yeej tsis poob hauv 60 feeb, thiab 10-20 feem pua ​​poob hauv 90 feeb;

4. Kev siv dav rau cov cement, kev ua haujlwm zoo thiab cohesion. Tau tshaj lwm yam admixtures;

5. Nws tuaj yeem txhim kho qhov khov-thaw tsis kam, impermeability, sulfate corrosion tsis kam ntawm pob zeb, thiab ua kom zoo dua lwm yam khoom ntawm lub cev ntawm pob zeb;

6. Nws yog tshwj xeeb tshaj yog haum rau cov nram qab no concretes: fluidized plasticized qhob, ntuj curing, steam curing qhob, impermeable thiab waterproof qhob, check anti-freeze-thaw qhob, anti-sulfate corrosion marine pob zeb, as Well as steel reinforcement thiab prestressed pob zeb. ;

7. HSB yog non-toxic, non-flammable, non-corrosive rau steel tuav, thiab tsis muaj sodium sulfate crystals nyob rau hauv lub caij ntuj no.
