Shotcrete Accelerator

Non-alkali kua accelerator khoom rau sprayed qhob qhov engineering

txhaj tshuaj accelerator

Taw qhia:
Sprayed pob zeb, tseem hu ua shotcrete, yog ib txoj kev siv dav rau kev tsim cov tunnels. Nws yog ib qho txheej txheem uas muaj kev txau cov pob zeb ntawm qhov siab tshaj plaws mus rau ib qho chaw nrog rab phom muaj zog tua hluav taws. Cov txheej txheem yog nyiam dua li cov txheej txheem ib txwm siv vim tias nws nrawm dua, ua haujlwm tau zoo, thiab siv nyiaj ntau dua. Txhawm rau kom ntseeg tau tias qhov kev ua tau zoo ntawm cov txheej txheem, cov khoom siv uas tsis yog-alkali kua accelerator yog siv.

Dab tsi yog cov khoom uas tsis yog-alkali accelerator?

Cov khoom lag luam uas tsis yog-alkali accelerator yog cov khoom sib xyaw ntxiv rau kev txhaj tshuaj kom nrawm rau kev teeb tsa thiab txheej txheem tawv. Cov khoom tsim tshwj xeeb tsim los ua kom cov hydration ntawm cov cement thiab txo lub sij hawm xav tau rau cov pob zeb kom ua tiav nws lub zog xav tau. Tsis zoo li lwm cov accelerators, cov kua accelerators uas tsis yog-alkali muaj cov ntsiab lus alkaline tsawg, uas tiv thaiv qhov tshwm sim ntawm alkali-tag nrho cov tshuaj tiv thaiv, ib qho teeb meem uas tuaj yeem tshwm sim hauv qee qhov sib xyaw ua ke.

Kev siv cov khoom tsis-alkali kua accelerator hauv tunnel engineering:
Cov khoom uas tsis yog-alkali kua accelerator yog zoo tagnrho rau siv nyob rau hauv tunnel engineering vim hais tias lawv ceev cov txheej txheem thiab hardening, ua rau nws muaj peev xwm tsim tunnels sai thiab ntau npaum. Cov khoom muaj txiaj ntsig tshwj xeeb tshaj yog thaum ua haujlwm hauv thaj chaw uas muaj kev txwv tsis pub nkag thiab lub taub hau, vim tias qhov chaw ceev ceev thiab cov khoom siv tawv tawv kom ntseeg tau tias lub qhov dej tuaj yeem txhawb nqa nws tus kheej yam tsis tas yuav muaj kev txhawb nqa ib ntus rau lub sijhawm ntev dua. Kev siv cov khoom uas tsis yog-alkali kua accelerator kuj txo cov kev pheej hmoo cuam tshuam nrog kev ua haujlwm hauv ib puag ncig nrog kev txwv lub taub hau.

Qhov zoo ntawm non-alkali kua accelerator khoom:
Qhov zoo ntawm kev siv cov khoom siv tsis-alkali kua accelerator hauv tunnel engineering muaj ntau heev. Qee qhov zoo muaj xws li:

- Kev teeb tsa sai dua thiab cov txheej txheem hardening, uas txo cov sijhawm ua haujlwm thiab tus nqi.
- Txo kev pheej hmoo ntawm qhov tshwm sim ntawm alkali-tag nrho cov tshuaj tiv thaiv.
- Ua kom muaj zog ntawm pob zeb.
- Txo kev pheej hmoo ntawm kev tawg.
- Txo qhov kev cia siab ntawm kev nyab xeeb, raws li cov khoom siv tuaj yeem siv rau ntau qhov kub thiab txias.
- Muaj kev nyab xeeb rau cov neeg ua haujlwm, vim tias kev siv cov khoom siv txo cov kev pheej hmoo cuam tshuam nrog kev ua haujlwm hauv qhov chaw kaw.

Xaus:
Hauv kev xaus, cov khoom lag luam uas tsis yog-alkali accelerator yog qhov tseem ceeb rau kev ua tiav ntawm kev ua tiav ntawm kev tsim vaj tse. Cov khoom lag luam txhim kho kev ua haujlwm ntawm cov txheej txheem, ua rau nws muaj peev xwm tsim cov tunnels sai dua, ua tau zoo dua, thiab siv nyiaj ntau dua. Lawv kuj nce kev nyab xeeb ntawm cov neeg ua haujlwm thiab txo cov kev pheej hmoo cuam tshuam nrog kev ua haujlwm hauv qhov chaw kaw. Los ntawm kev siv cov khoom lag luam uas tsis yog-alkali kua accelerator, cov kws ua haujlwm hauv av tuaj yeem ua kom lawv cov haujlwm ua tiav raws sijhawm, ntawm kev siv nyiaj txiag, thiab rau cov qauv zoo tshaj plaws thiab kev nyab xeeb.
