Taw qhia rau polycarboxylate dej txo tus neeg sawv cev

Polycarboxylate dej-txo tus neeg saib xyuas yog lub cim tshiab ntawm cov dej-txo cov neeg ua haujlwm siab. Nws yog cov txheej txheem technical. Cov molecule muaj sulfonic acid pawg, carboxylic acid pawg thiab ntau ceg chains. Nws muaj cov yam ntxwv ntawm kev siv tsawg tsawg, txo cov dej kom tsawg, thiab khaws cia zoo. Nta. Nws tuaj yeem ua kom cov pob zeb ua kom muaj zog, txo cov qhob shrinkage thiab txhim kho pob zeb durability. Nws tuaj yeem siv dav hauv kev siv cov pob zeb, nws tus kheej condensing pob zeb, muaj zog thiab ruaj khov, thiab cov pob zeb ua haujlwm siab.

1. Polycarboxylate dej-txo tus neeg sawv cev muaj cov dej zoo txo ​​cov khoom ntawm qhov tsawg, thiab tus nqi txo cov dej tuaj yeem ncav cuag 25-45%.

2. Polycarboxylate superplasticizer muaj cov ntsiab lus alkali qis thiab tsis muaj chloride ions. Nws yuav tsis ua rau alkali aggregate cov tshuaj tiv thaiv thiab yuav tsis corrode steel tuav.

3. Polycarboxylate dej-txo tus neeg saib xyuas muaj qhov zoo dispersion thiab slump tuav, thiab tuaj yeem siv los npaj cov pob zeb nrog cov fluidity loj.

4. Polycarboxylate dej-txo tus neeg sawv cev tuaj yeem txo cov pob zeb los ntshav yam tsis muaj kev sib cais, ua kom yooj yim los npaj cov pob zeb ua kom muaj zog.

5. Polycarboxylate dej-txo tus neeg sawv cev tuaj yeem siv los npaj ntau hom kev lag luam pob zeb. Ncuav ua ntej thiab precast qhob uas muaj fluidity thiab siab zog.

yam ntxwv:

Tus nqi txo qis (ua rau lub kaw lus siab dua thiab lub zog)

Cov khoom ntws zoo heev (txo lub sijhawm tsim kho thiab kev siv zog compaction)

Zoo thaum ntxov thiab lig zog

Ceev ceev adsorption txo cov sij hawm sib tov

Txhim kho shrinkage thiab creep zog

Kev ua haujlwm ruaj khov thiab khaws cia ntev
