Naphthalene-based High-performance Dej txo tus neeg sawv cev

Naphthalene-based high-performance dej txo tus neeg saib xyuas yog ib tiam tshiab ntawm cov dej ua tau zoo txo ​​tus neeg saib xyuas. Nws yog ua los ntawm naphthalene sulfonate formaldehyde condensate thiab lwm yam khoom zoo raw khoom los ntawm kev siv tshuab ntau lawm. Nws muaj cov yam ntxwv ntawm kev siv tshuaj tsawg, txo qis dej ntau, ua haujlwm tau zoo, thiab lub zog siab.

Cov khoom siv dav siv hauv ntau yam kev ua vaj tse, xws li cov pob zeb ua haujlwm siab, cov pob zeb muaj zog, thiab cov pob zeb ua rau nws tus kheej. Nws tuaj yeem txhim kho fluidity thiab pumpability ntawm pob zeb, txo cov dej-cement piv, txo cov ntshav thiab cais cov pob zeb, thiab txhim kho kev ua haujlwm ntawm pob zeb thaum lub sij hawm tsim kho. Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho lub zog thiab kav ntev ntawm cov pob zeb, nrog rau txo qhov shrinkage thiab tawg ntawm pob zeb.

Piv nrog rau cov tshuaj txo cov dej ib txwm muaj, naphthalene-raws li kev ua haujlwm siab dej txo tus neeg saib xyuas muaj cov hauv qab no zoo:

1. Cov dej txo qis: Cov khoom lag luam tuaj yeem txo cov dej-cement piv ntawm cov pob zeb, ua kom cov ntsiab lus zoo, thiab txhim kho cov compactness thiab durability ntawm pob zeb.

2. Kev ua haujlwm tau zoo: Cov khoom lag luam tuaj yeem txhim kho qhov fluidity thiab pumpability ntawm pob zeb, txo qhov poob ntawm cov pob zeb, thiab ua kom cov pob zeb ua haujlwm yooj yim.

3. Lub zog siab thiab ua haujlwm ntev: Cov khoom tuaj yeem txhim kho lub zog thaum ntxov thiab tom qab ntawm cov pob zeb, txo qhov ziab kom qhuav thiab tawg ntawm cov pob zeb, thiab txhim kho cov pob zeb ua kom muaj zog.

4. Kev siv dav dav: Cov khoom siv tuaj yeem siv dav hauv ntau yam kev ua vaj tse, xws li cov pob zeb ua haujlwm siab, cov pob zeb muaj zog, thiab cov pob zeb ua rau nws tus kheej. Nws kuj tseem siv tau rau hauv ntau yam haujlwm engineering, xws li txuas hniav, tunnels, cov tsev siab siab, thiab dams.

5. Tus nqi tsim nyog: Cov khoom lag luam muaj kev siv tsawg thiab kev ua haujlwm siab, uas tuaj yeem txo tus nqi ntawm kev tsim vaj tse.

Hauv cov ntsiab lus, naphthalene-based high-performance dej txo tus neeg sawv cev yog ib qho kev ua tau zoo ntxiv uas tuaj yeem txhim kho qhov zoo thiab ua haujlwm ntawm kev tsim vaj tsev. Nws yog dav siv nyob rau hauv ntau yam kev ua vaj tse thiab tau dhau los ua ib feem tseem ceeb ntawm kev tsim vaj tsev niaj hnub.
