Dab tsi yog Kev Siv Cov Hmoov Pob Zeb Accelerator
Apr 22, 2024
Lub hmoov pob zeb accelerator yog cov tshuaj tshwj xeeb sib xyaw tsim los ua kom nrawm nrawm thiab txheej txheem ntawm cov pob zeb.
Khoom nta:
Kev sib xyaw: Feem ntau ua los ntawm alumina clinker thiab ntau yam inorganic ntsev, finely hauv av los txhawb kev ceev ceev ntawm pob zeb nyob rau hauv feeb.
Cov khoom: Muab kev teeb tsa sai thiab tawv, lub zog thaum ntxov, thiab nthuav me ntsis. Nws muaj zog yoog tau rau cov cement sib txawv nrog lub sijhawm pib ntawm 2 mus rau 4 feeb thiab lub sijhawm kawg ntawm 4 mus rau 8 feeb.
Kub rhiab heev: Lub sijhawm teeb tsa ntawm cov cement yog qhov cuam tshuam los ntawm qhov kub thiab txias; qis dua 20 degree, yuav tsum tau noj ntau ntxiv.
Txhim kho kev ua haujlwm: Kev sib xyaw cov khoom no txhim kho kev ua haujlwm thiab homogeneity ntawm cov pob zeb tsis muaj kev cuam tshuam nws lub zog. Nws ua tsis muaj plua plav ntawm qhov chaw ua haujlwm, muaj alkalinity tsawg, thiab tsawg corrosiveness, uas muaj txiaj ntsig zoo rau kev noj qab haus huv ntawm cov neeg ua haujlwm.
Khoom siv:
Rau Shotcrete: Feem ntau siv rau hauv cov ntawv thov kev txhaj tshuaj xws li kev txhawb nqa engineering hauv av, kev tsim kho ntawm lub ru tsev nyias nyias, cov roj tso tsheb hlau luam prestressed, thiab kho thiab txhim kho cov haujlwm.
Rau Refractory thiab Kho Projects: Siv nyob rau hauv refractory pob zeb thiab sealing tej yaam num nyob rau hauv ib puag ncig xws li mine shafts, txoj kev loj thiab railway tunnels, thiab pob zeb anchoring.
Pom zoo Dosage:
Qhov pom zoo noj yog 4% ntawm cov cement hnyav. Kev noj tshuaj tiag tiag yuav tsum tau hloov kho raws li hom thiab qib ntawm cov cement thiab qhov kub ntawm qhov kev tsim kho.
Txoj kev thov:
Cement Requirements: Siv nrog Portland cement qib 32.5 lossis siab dua. Kev ntsuam xyuas tsim nyog yuav tsum tau ua ua ntej siv los txiav txim siab txog qhov zoo tshaj plaws.
Shotcrete Mix Ratio: Cov tshuaj tua kab mob sib xyaw siv 350 kg ntawm cement ib lub cubic meter, nrog xuab zeb piv ntawm 60% thiab dej-rau-cement piv ntawm 0.42 txog 0.50.
Aggregate Specifications: Shotcrete yuav tsum siv pebbles los yog crushed pob zeb nrog lub siab tshaj plaws txoj kab uas hla ntawm 20mm thiab xuab zeb nrog ib tug fineness modulus ntau tshaj 2.5.
Tswj dej: nruj me ntsis tswj cov dej kom tswj tau qhov xav tau dej-rau-cement piv; Cov dej ntau dhau tuaj yeem txo qhov ua tau zoo ntawm cov accelerator.
Siv tam sim ntawd: Cov pob zeb qhuav qhuav uas muaj cov tsuj roj yuav tsum tau siv tam sim ntawd tom qab sib tov thiab tsis khaws cia ntev tshaj li ob teev.
Kev saib xyuas thaum ntxov: Txhim khu kev kho thaum ntxov ntawm cov pob zeb ua haujlwm siv lub tshuab accelerator kom ntseeg tau tias muaj kev cuam tshuam cov dej muaj txiaj ntsig zoo thiab txo qis lub zog poob hauv cov theem tom ntej.
