Taw qhia ntawm polycarboxylic acid dej txo tus neeg sawv cev

Polycarboxylic acid dej txo tus neeg saib xyuas yog lub cim tshiab ntawm cov dej txo cov neeg ua haujlwm siab, cov txheej txheem kev, cov molecule muaj sulfonic acid pawg, carboxylic acid pawg thiab ntau ceg saw, nrog tsawg npaum li cas, txo cov dej siab, slump-proof thiab lwm yam. . Nws tuaj yeem txhim kho lub zog ntawm pob zeb, txo qhov shrinkage ntawm pob zeb thiab txhim kho lub durability ntawm pob zeb. Nws tuaj yeem siv dav hauv kev siv cov pob zeb, nws tus kheej-compacting pob zeb, muaj zog thiab ruaj khov pob zeb, kev ua haujlwm siab.

1, Polycarboxylic acid dej txo tus neeg sawv cev muaj cov dej zoo txo ​​cov cuab yeej nyob rau hauv qis npaum li cas, thiab cov dej txo tus nqi tuaj yeem ncav cuag 25-45%.

2, Polycarboxylic acid dej txo tus neeg sawv cev muaj cov ntsiab lus alkali qis, tsis muaj chlorine ion, yuav tsis ua rau alkali aggregate cov tshuaj tiv thaiv, tsis muaj corrosion ntawm hlau, alkali cov ntsiab lus tsawg dua los yog sib npaug li 4%. Cov ntsiab lus alkali tsawg dua 4% thiab cov ntsiab lus chlorine ion tsawg dua 0.03%. Cov ntsiab lus 40± 1.0 & 50 ± 1.0.

3, Polycarboxylic acid dej txo tus neeg sawv cev muaj qhov zoo dispersibility thiab slump-proof, thiab tuaj yeem siv los tsim cov pob zeb loj loj.

4, Polycarboxylic acid dej txo tus neeg sawv cev tuaj yeem txo qis cov dej tso tawm, thiab tsis muaj qhov tshwm sim sib cais, yooj yim los tsim cov pob zeb muaj zog.

5, Polycarboxylic acid dej txo tus neeg sawv cev tuaj yeem tsim txhua yam kev lag luam pob zeb. Nws tuaj yeem siv rau hauv thawj lub ncuav thiab prefabrication ntawm kev txav mus los loj thiab muaj zog ua vaj tse.

Yam ntxwv:

Tus nqi txo qis (ua rau lub cev muaj zog thiab muaj zog)

Kev ua tau zoo flowability (txo lub sij hawm tsim kho thiab kev ua haujlwm compaction)

Zoo thaum ntxov thiab lig zog

Ceev ceev adsorption txo cov sij hawm sib tov

Txhim kho shrinkage thiab creep zog

Cov khoom ruaj khov rau kev khaws cia ntev
