Tshuab ntau lawm ntawm cov kua alkali-free accelerator masterbatch

A Sai-teeb tsa admixtureyog hom pob zeb ua ntxiv uas nrawm dua cov txheej txheem thiab cov txheej txheem ua kom tawv nqaij tawv. Tam sim no, dav siv ceev ceev-teeb tsa edixtures muaj cov khoom siv alkali muaj zog hauv lawv cov ntaub ntawv raw. Thaum lawv ua tiav qhov kev teeb tsa tau xav tau sai, lawv kuj nce cov ntsiab lus Alkali hauv cov qauv pob zeb tawv. Thaum cov pob zeb ua hluav taws xob muaj cov dej noo, lawv zoo li nqus noo noo, ua rau sodium ion nag los, thiab txo kev ua haujlwm lub neej ntawm cov qauv ua vaj tse.

Yuav kom kov yeej lub drawbacks ntawm Alkali-based nrawm nrawm-concixtures,Alkali-Dawb ceev ceev-teeb tsa Admixturestau nce ntxiv cov koob meej nyob rau hauv xyoo tsis ntev los no. Lawv tau dav siv nyob rau hauv cov tebchaws tsim khoom xws li cov neeg nyob hauv Tebchaws Europe thiab North America, thiab lawv txoj kev yuav loj hlob nyob hauv Suav teb ib yam nkaus. Piv rau alkali-based nrawm nrawm, cov lus Askiv-dawb ceev ceev-teeb tsa admixtures muaj ob peb qhov zoo, suav nrogib puag ncig kev ua phooj ywg, lub sijhawm ntev, siab dua ntev lub sij hawm compressive muaj zog khaws cia, thiab zoo dua qub.

Txawm li cas los xij, kev siv cov kev siv engineering tau qhia qee qhov teeb meem nrogKua alkali-dawb ceev ceev-teeb tsa Admixtures, feem ntau yog:

1. Rau qee hom xis mas, aNtau duayuav tsum ua tiav cov nyhuv tseem ceeb.
2. Thaum lubTeem sijhawm raws li cov cai, tus{{0 {0}}} Hnub Compressive Lub Zog yog tsawg(xis tiag cug colrter compressive zog<7MPa), and in some cases, it may not develop any strength or harden properly.
3. Kev sib raug zoo uas tsis zoonrog qee hom cement.
