Alkali-dawb Liquid Accelerator Quick-setting Agent yog Ib hom tshiab ntawm pob zeb additive

Alkali-dawb kua accelerator ceev-teeb tus neeg saib xyuas yog ib yam tshiab ntawm cov qhob additive, haum rau ntau yam ntub shotcrete tej yaam num, thiab nws cov txheej txheem muaj raws li nram no:

Ua ntej, ntxiv cov khoom siv pob zeb hauv qhov chaw sib xyaw ua ke, suav nrog cov cement, nplua aggregate, coarse aggregate thiab admixture, thiab lwm yam, thiab tom qab ntawd do cov sib tov sib npaug los ua ib qho kev sib xyaw ua ke.

Tom ntej no, cov pob zeb slurry raug thauj mus rau chav tsev txau, compressed thiab txau los ntawm lub twj tso kua mis siab siab los tsim cov pob zeb txau txheej.

Txhawm rau txhim kho lub zog thiab ua haujlwm ntev ntawm cov pob zeb tshuaj tsuag txheej, nws yog ib qho tsim nyog yuav tau ntxiv cov kua alkali-dawb accelerator. Nws txoj kev sib ntxiv yog sib tov cov kua tsis-alkali ceev-teeb tsa tus neeg sawv cev nrog dej, thiab tom qab ntawd ntxiv rau hauv cov tshuaj txau cov pob zeb slurry. Cov pob zeb yuav ua kom tiav qhov kev teeb tsa thawj zaug thiab thaum ntxov hardening thaum txau, txhim kho cov adhesion thiab compactness ntawm slurry, thiab ua kom cov pob zeb txau txheej txheej muaj zog thiab ruaj khov.

Thaum kawg, tom qab lub pob zeb txau txheej yog qhuav thiab solidified, cov txheej txheem tom ntej tuaj yeem ua tiav.

Feem ntau, kev siv cov kua alkali-dawb accelerator zoo heev txhim kho cov txheej txheem kev ua haujlwm thiab kev tsim kho zoo ntawm cov pob zeb ntub dej, thiab ua lub luag haujlwm tseem ceeb hauv kev txuag nqi thiab txhim kho qhov project zoo hauv kev tsim kho.
