Alkali-dawb accelerator

Alkali-dawb accelerator

Cov accelerator tsis muaj alkali yog tsim los ntawm cov khoom siv tshuaj xws li sulfoaluminate, ester plasticizer, catalyst, thiab lwm yam, tsis muaj chloride ions, tsis muaj K ntxiv, Na ntxiv ions ntawm alkali hlau, tsis corrode steel tuav, tsis muaj kuab paug. ib puag ncig thiab ua phem rau cov neeg ua haujlwm. lub cev; tshuaj tsuag
Cement slurry, cement mortar, thiab pob zeb yog sib xyaw nrog cov kev ua haujlwm siab uas tsis yog-alkali ceev-setting tus neeg saib xyuas, uas tuaj yeem ua kom nrawm qhov chaw thiab hardening ceev ntawm cov cement thiab txhim kho lub zog thaum ntxov.
, qhov cuam tshuam rau lub zog tom qab me me, lossis txawm tias tsis txo qis; thiab kev sib koom ua ke thiab kev sib koom ua ke ntawm cov pob zeb thiab mortar tau txhim kho zoo heev, thiab tus nqi rov qab yog txo los ntawm ntau dua 80 feem pua, uas ua rau txo cov khoom poob los ntawm kev rov qab los thiab txhim kho cov txiaj ntsig Kev Lag Luam, vim qhov txo qis rov qab zoo heev, alkaline cement plua plav uas ua rau huab cua phem thiab ua rau tib neeg lub cev raug txo kom tsawg, uas tiv thaiv ib puag ncig thiab ua kom cov kev tsim kho sai; Nws muaj cov nyhuv ntawm micro-expansion, shrinkage thiab tawg tsis kam, thiab zoo heev txhim kho lub impermeability thiab dej tsis kam Nws muaj anti-corrosion thiab anti-corrosion zog, thiab nws corrosion kuj coefficient yog nce los ntawm ntau tshaj 50 feem pua ​​piv nrog rau cov accelerators zoo tib yam; High-performance accelerators yog cov khoom siv rau kev txau cov pob zeb ua haujlwm siab, alkali aggregate active qhob, ua vaj tse ruaj khov, thiab kev tiv thaiv ib puag ncig.
Lub tshuab ua haujlwm siab muaj cov khoom zoo heev ntawm cov dej txo, kev teeb tsa ceev, lub zog thaum ntxov, kev txhawb zog, micro-expansion, anti-crack, anti-seepage, anti-corrosion thiab anti-corrosion. Cov kev ua tau zoo ntawm cov pob zeb sib xyaw ua tau raws li qhov yuav tsum tau ua ntawm JC477-2005 cov khoom lag luam thawj zaug.

Khoom siv:
High-performance alkali-free accelerator yog tsim nyog rau kev npaj cov tshuaj tsuag hom kev ua tau zoo pob zeb thiab mortar, ceev-teeb thaum ntxov-lub zog pob zeb rau dej sealing thiab ntsaws; thawj txheej txheej pob zeb thiab mortar rau tunnels xws li railways, highways, thiab hydraulic diversion tunnels, raws li zoo raws li metallurgy, thee mines, thiab lwm yam. Nyias-walled pob zeb (mortar) reinforcement, kho, foundation pit retaining phab ntsa, hluav taws-resistant engineering, thiab kev tiv thaiv engineering rau lub qhov dej thiab txoj kab, kev ua tub rog kev lag luam, thiab underground engineering ntawm kev tiv thaiv huab cua.
