Polycarboxylate Ether Monomer HPEG / TPEG

TPEG

1. Cov khoom no tsis muaj tshuaj lom, tsis ua rau khaus, muaj dej solubility zoo, yog soluble hauv dej thiab ntau yam organic solvents, thiab yog ib qho tseem ceeb raw khoom rau ib tiam tshiab ntawm high-efficiency kua nplaum tshuab.

2. Lub molecular hnyav tis ntawm cov khoom no yog nqaim, cov ntsiab lus ntawm polyethylene glycol yog tsawg, tus nqi tuav ntawm ob daim ntawv cog lus yog siab, thiab cov kev ua ntawm polymerization zoo heev.Kev hloov pauv ntawm cov khoom yog siab.Kev ua tau zoo ntawm tus neeg sawv cev zoo heev.3. Cov dej-txo tus neeg sawv cev tsim los ntawm cov khoom no muaj kev ua haujlwm siab ntawm cov khoom tawg thiab kev tuav pov hwm, thiab muaj kev cuam tshuam zoo rau ntau cov ntaub ntawv hmoov xws li cement.Nws muaj cov dej-txo qis thiab siv cov cement tsawg.Qhov zoo ntawm cov cement ntxiv yog 0.2% -0.5% Concrete water reducer, dej txo tus nqi tuaj yeem ncav cuag ntau dua 30%.

4. Tom qab ntxiv cov dej txo tus neeg sawv cev rau cov pob zeb, ib zaj duab xis adsorption yog tsim nyob rau saum npoo ntawm cov cement hais, uas slows lub hydration tus nqi ntawm cov cement, ua rau kev loj hlob ntawm cov cement pob zeb siv lead ua zoo meej, txo cov capillary voids ntawm dej. evaporation, thiab cov qauv kev sib txuas yog ntau ntom, uas tuaj yeem txhim kho cov pob zeb siv tau ntau dua 20%.Nws tuaj yeem siv rau lub zog siab (siab dua C60) kev lag luam pob zeb.

5. Cov dej-txo tus neeg sawv cev ua ke los ntawm cov khoom no tuaj yeem txhim kho rheology thiab plasticity ntawm pob zeb.Nws tuaj yeem ua tiav kev tsim vaj tsev los ntawm kev siv tus kheej ntws, tso dej, thiab tsis muaj kev vibration, uas tuaj yeem ua rau kev tsim kho ceev thiab txo nqi kev tsim kho.

6. Cov khoom no yog cov khoom lag luam ntsuab thiab ib puag ncig zoo, cov ntsiab lus chloride ion: ≤0.1%.Ua raws li ISO14001 thoob ntiaj teb kev tswj hwm kev tiv thaiv ib puag ncig.

HPEG

1. Cov khoom no muaj dej solubility zoo.

2. Cov khoom no siv cov catalyst muaj zog heev thiab cov txheej txheem synthesis tshwj xeeb.Qhov hnyav molecular faib yog nqaim, cov ntsiab lus ethylene glycol tsawg, thiab ob daim ntawv cog lus khaws cia yog siab.Kev ua haujlwm polymerization tau zoo heev, cov khoom hloov pauv tau siab, polycarboxylic acid dej reducer khoom tsim los ntawm cov khoom muaj cov ntsiab lus zoo, thiab cov dej reducer muaj kev ua tau zoo heev.

3. Kev ua tau zoo thiab qhov Performance index ntawm hluavtaws dej reducer:

1) Kev ua haujlwm siab heev.Nyob rau hauv cov ntaub ntawv ntawm kev ua tau zoo tib yam dej txo tus nqi, nws muaj ib tug high nqi kev ua tau zoo.

2) Tsawg admixture thiab dej txo tus nqi siab.Cov dej-txo tus neeg sawv cev niam cawv nrog cov ntsiab lus ntawm 20% thiab cov dej txo qis ntawm 1.0% (cov khoom siv cementing) tuaj yeem ncav cuag 30-35%.

3) Zoo plasticity tuav.Lub slump poob ntawm pob zeb tom qab 1h yog me me.

4) Zoo heev durability.Muaj peev xwm txo tau cov dej haus thiab txhim kho cov kav dej ntawm cov pob zeb.

5) Ntsuab thiab kev tiv thaiv ib puag ncig.Nyob rau hauv cov txheej txheem ntawm cov dej reducer, tsis muaj formaldehyde thiab chloride ion tsim kev puas tsuaj rau ib puag ncig, thiab cov ntsiab lus ntawm sulfate tsawg.
