Alkali-dawb Rapid Hardening Agent / accelerator Rau Cov Nroj Tsuag ntub dej ua nrov

Alkali-dawb ceev ceev hardening tus neeg saib xyuas / accelerator rau ntub txau pob zeb ua nrov

Tsis ntev los no, kev siv cov alkali-dawb ceev ceev hardening tus neeg saib xyuas rau cov ntub dej txau pob zeb tau ua nrov nrov hauv cov haujlwm tsim kho. Hom tshiab ntawm hardening tus neeg sawv cev no yog tus cwj pwm los ntawm lub sijhawm ceev ceev, lub zog thaum ntxov, thiab qis qis.

Cov pob zeb ntub dej ntub dej feem ntau yog siv hauv tunneling, mining, thiab txoj kab nqes stabilization. Nws yog ib qho tseem ceeb uas cov pob zeb ua kom tawv nqaij sai sai los muab kev txhawb nqa tam sim ntawd thiab tiv thaiv kev yaig lossis tawg ntxiv. Txawm li cas los xij, cov tshuaj tawv tawv tawv feem ntau muaj cov alkali, uas tuaj yeem ua rau corrosion thiab cuam tshuam rau lub zog ntawm cov pob zeb thaum lub sijhawm.

Borida alkali-dawb ceev ceev hardening neeg sawv cev yog ib qho kev daws teeb meem rau cov teeb meem no. Nws yog tsim los ntawm cov khoom tsis-alkaline raw khoom thiab muaj qhov nruab nrab pH tus nqi. Nws tseem tuaj yeem ncav cuag lub zog compressive tshaj 20 MPa hauv 4 teev ntawm kev txau, uas yog nrawm dua li cov tshuaj tawv tawv tawv.

Tsis tas li ntawd, qhov tsawg shrinkage yam ntxwv ntawm cov alkali-dawb ceev ceev hardening tus neeg saib xyuas txo qhov kev pheej hmoo ntawm cracking thiab txhim kho lub durability ntawm cov pob zeb. Nws kuj txo cov nqi kho thiab kho cov nqi hauv lub sijhawm ntev.

Raws li qhov txiaj ntsig ntawm nws cov txiaj ntsig ntau, kev lag luam xav tau rau cov alkali-dawb ceev ceev hardening tus neeg sawv cev rau cov tshuaj tsuag ntub dej yog nce. Ntau lub tuam txhab tsim kho tau hloov mus rau cov thev naus laus zis tshiab no thiab muab tso rau hauv lawv cov haujlwm. Kev siv tus neeg sawv cev hardening no tsis tsuas yog ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm cov txheej txheem kev tsim kho, tab sis kuj tseem txhawb nqa kev txhim kho kev lag luam.
