Alkali free kua accelerator Nthuav txau pob zeb

Alkali tsis muaj kua accelerator
Cov pob zeb ntub dej ntub dej yog cov khoom siv ntau yam thiab siv tau ntev uas feem ntau siv rau ntau yam kev siv, nrog rau hauv ob sab phlu, kev txhawb nqa hauv av, thiab kev kho vaj tse. Ib qho tseem ceeb uas cuam tshuam rau kev ua tau zoo thiab kev ua haujlwm ntawm cov pob zeb ntub dej yog hom kev txhaj tshuaj nrawm uas siv.

Tsoos tshuaj tua kab mob accelerants, xws li alkali-raws li cov khoom, tau siv ntau xyoo los ua kom qhov chaw thiab ua kom tawv nqaij ntawm cov pob zeb ntub dej. Txawm li cas los xij, cov khoom no muaj qee qhov tsis zoo, xws li kev ua haujlwm qis dua, muaj kev pheej hmoo ntawm alkali-silica cov tshuaj tiv thaiv, thiab kev txhawj xeeb ntawm ib puag ncig.

Txhawm rau daws cov teeb meem no, ib hom tshiab ntawm cov tshuaj tua kab mob accelerator tau tsim - cov kua accelerator uas tsis yog-alkaline. Cov khoom no yog lwm txoj hauv kev zoo rau cov tsoos accelerants, vim nws muab ntau qhov zoo. Ua ntej, nws tsis yog-alkaline, uas txhais tau hais tias nws tsis nce qib pH ntawm cov pob zeb thiab tsis ua rau muaj kev pheej hmoo ntawm alkali-silica cov tshuaj tiv thaiv. Qhov thib ob, nws yog cov khoom ua kua, uas ua rau nws yooj yim dua los tuav, thauj thiab khaws cia. Thaum kawg, nws muaj kev ua haujlwm siab dua li cov khoom siv accelerators, uas ua rau nws yooj yim rau kev thov thiab muab cov pob zeb ua kom tiav.

Alkali free kua accelerators feem ntau yog ib qho kev sib xyaw ntawm cov organic thiab inorganic chemicals, uas yog tsim los kom ceev cov cement hydration txheej txheem thiab ua kom muaj zog ntau dua hauv lub sijhawm luv. Lawv feem ntau yog ntxiv rau cov dej ntub dej sib tov ntawm lub nozzle, xws li los ntawm kev txhaj tshuaj cais lossis los ntawm kev sib xyaw ncaj qha nrog dej ua ntej nws nkag mus rau hauv lub tshuab txhaj tshuaj.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov, uas tsis yog-alkaline kua accelerators yuav siv tau rau ntau yam ntawm ntub dej sprayed pob zeb tej yaam num, nrog rau mine ua hauj lwm, tunneling, thiab txoj kab nqes stabilization. Lawv kuj muaj txiaj ntsig zoo rau kev kho vaj tse thiab kev siv zog ntxiv.

Nyob rau hauv xaus, cov kua accelerators uas tsis yog-alkaline yog ib tug txhim khu kev qha, muaj kev nyab xeeb, thiab tus nqi-zoo lwm txoj rau ib txwm alkali-based shotcrete accelerants. Lawv muab ntau cov txiaj ntsig, suav nrog kev ua haujlwm siab dua, txo qis kev pheej hmoo ntawm alkali-silica cov tshuaj tiv thaiv, thiab yooj yim tuav thiab khaws cia. Nrog lawv cov kev ua tau zoo thiab kev ua tau zoo, lawv yog qhov tseem ceeb ntxiv rau kev lag luam ntub dej ntub dej, thiab zoo li yuav dhau los ua neeg nyiam dua yav tom ntej.
