Lub luag hauj lwm ntawm txhuas sulfate ua raw khoom rau zus tau tej cov pob zeb accelerators rau shotcrete tunnel engineering
May 02, 2023
Aluminium sulfate yog ib hom inorganic compound nrog cov tshuaj formula Al2 (SO4) 3 thiab feem ntau muaj nyob rau hauv daim ntawv. Nws yog dav siv nyob rau hauv zus tau tej cov pob zeb accelerators, tshwj xeeb tshaj yog nyob rau hauv shotcrete tunnel engineering.
Concrete tunneling yog ib qho txheej txheem uas feem ntau siv thaum tsim cov tunnels lossis hauv av ua haujlwm. Txhawm rau kom ntseeg tau tias qhov project zoo, cov pob zeb ua haujlwm zoo yuav tsum tau siv. Accelerator yog ib qho tseem ceeb raw cov ntaub ntawv nyob rau hauv cov pob zeb ntau lawm, nws muaj peev xwm leeb lub teeb thiab hardening txheej txheem ntawm pob zeb, li no shortening lub sij hawm tsim kho.
Raws li cov khoom siv raw ntawm pob zeb accelerator, aluminium sulfate muaj cov yam ntxwv hauv qab no:
1. Ceev ceev solidification: Aluminium sulfate tuaj yeem ua kom cov pob zeb sai sai, txhawb kev sib xyaw ua ke sai dua ntawm cov cement, thiab txhim kho lub zog thiab hardness ntawm pob zeb.
2. Txhim kho fluidity: Aluminium sulfate tuaj yeem txhim kho qhov fluidity ntawm cov pob zeb, ua kom yooj yim rau cov pob zeb kom sau tag nrho cov voids thiab tsim ib qho chaw sib xws, uas yog qhov tseem ceeb tshwj xeeb rau kev tsim vaj tsev.
3. Txo cov shrinkage: Aluminium sulfate tuaj yeem txo qhov shrinkage ntawm pob zeb thaum lub sij hawm teeb tsa thiab hardening txheej txheem, yog li tsis txhob muaj teeb meem xws li tawg thiab to.
4. Kev ua haujlwm siab thiab kev txuag hluav taws xob: Kev sib ntxiv ntawm aluminium sulfate tuaj yeem tsis tsuas yog txhim kho lub zog thiab hardness ntawm pob zeb, tab sis kuj txuag lub sijhawm thiab lub zog uas yuav tsum tau ua rau pob zeb ntau lawm, yog li ua tiav kev ua haujlwm siab thiab txuag hluav taws xob.
Nyob rau hauv luv luv, lub luag hauj lwm ntawm txhuas sulfate raws li ib tug raw khoom rau zus tau tej cov pob zeb accelerators rau shotcrete tunnel engineering yog nws tus kheej-pov thawj. Nws tuaj yeem txhim kho qhov zoo ntawm kev ua vaj tse thiab kev tsim kho kom zoo, ua rau kev tsim kho qhov av muaj kev nyab xeeb thiab txhim khu kev qha. Nyob rau tib lub sijhawm, kev siv cov txhuas sulfate kuj yuav tsum tau tswj xyuas kom zoo kom ntseeg tau tias kev ua tau zoo ntawm cov pob zeb ua tau raws li qhov xav tau ntawm engineering.
