Kev piav qhia txog khoom
Cov txheej txheem tiv thaiv hluav taws uas tsis nthuav dav yog qhov tsim nyog rau kev txau rau ntawm qhov chaw ntawm cov qauv hlau, tsim ib txheej ntawm cov rwb thaiv cua sov thiab txheej tiv thaiv hluav taws, uas tiv thaiv cov qauv hlau ntawm hluav taws los ntawm kev muab rwb thaiv tsev. Cov txheej txheem tiv thaiv hluav taws tuab feem ntau yog cov khoom siv rwb thaiv tsev kub inorganic, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, thiab muaj cov yam ntxwv ntawm kev tsim kho yooj yim thiab ceev, kev nplaum txheej muaj zog, lub zog kho tshuab siab, lub sijhawm tiv thaiv hluav taws ntev, kev ua haujlwm tiv thaiv hluav taws ruaj khov thiab txhim khu kev qha, thiab muaj peev xwm tiv taus kev cuam tshuam hnyav los ntawm cov nplaim taws kub xws li hydrocarbons. Lub tuab ntawm cov txheej txheem tuab yog 8-50 hli. Cov txheej txheem tsis ua npuas ncauj thaum cua sov thiab vam khom nws cov thermal conductivity qis dua los ua kom ntev qhov kub ntawm cov qauv hlau thiab ua lub luag haujlwm hauv kev tiv thaiv hluav taws.
siv ntau yam
Cov txheej txheem tiv thaiv hluav taws kub ntawm cov qauv hlau tsis nthuav dav tsis yog tsuas yog tsim rau kev tiv thaiv hluav taws ntawm ntau yam qauv hlau uas muaj lub nra hnyav hauv ntau hom tsev xws li cov tsev siab, roj av, tshuaj lom neeg, fais fab, metallurgy, thiab kev lag luam lub teeb, tab sis kuj siv tau rau qee cov qauv hlau uas muaj kev phom sij hluav taws los ntawm cov tshuaj hydrocarbon (xws li roj, cov kuab tshuaj, thiab lwm yam), xws li kev tiv thaiv hluav taws rau kev tsim roj av, chaw nres tsheb, cov chaw khawb roj, thiab cov thav ntawv txhawb nqa ntawm cov chaw khaws roj, thiab lwm yam.

Txoj Kev Tsim Kho
(I) Kev Npaj Ua Ntej Kev Tsim Kho
1. Ua ntej txau, tshem tawm cov khoom uas lo rau, cov khoom tsis huv, thiab cov hmoov av ntawm qhov chaw ntawm cov qauv hlau.
2. Rau cov khoom siv hlau uas muaj xeb, ua kev kho xeb thiab siv xim tiv thaiv xeb (xaiv cov xim tiv thaiv xeb uas nplaum zoo). Tsis txhob tsuag kom txog thaum cov xim qhuav.
3. Qhov kub ntawm qhov chaw tsim kho yuav tsum siab tshaj 3 ℃.
(II) Txoj Kev Txau
1. Kev sib tov cov txheej yuav tsum tau ua raws li qhov yuav tsum tau ua, thiab cov khoom yuav tsum tau ntim raws li qhov yuav tsum tau ua. Ua ntej, muab cov khoom ua kua rau hauv lub tshuab sib tov rau 3-5 feeb, tom qab ntawd ntxiv cov khoom hmoov thiab sib tov kom txog thaum sib xws.
2. Siv cov khoom siv txau rau kev tsim kho, xws li cov tshuab txau, cov tshuab cua, cov thoob khoom siv, thiab lwm yam; cov cuab yeej siv xws li cov khoom sib tov mortar, cov cuab yeej rau plastering, trowels, cov thoob khoom siv, thiab lwm yam. Thaum lub sijhawm tsim kho txau, qhov tuab ntawm txhua txheej txheej yuav tsum yog 2-8 hli, thiab lub sijhawm tsim kho yuav tsum yog 8 teev. Lub sijhawm tsim kho yuav tsum tau kho kom haum thaum qhov kub thiab txias ib puag ncig sib txawv. Thaum lub sijhawm tsim kho txheej thiab 24 teev tom qab tsim kho, qhov kub thiab txias ib puag ncig yuav tsum tsis txhob qis dua 4 ℃ kom tiv thaiv kev puas tsuaj los ntawm te; nyob rau hauv qhov chaw qhuav thiab kub, nws yog ib qho tsim nyog los tsim cov xwm txheej txij nkawm tsim nyog kom tiv thaiv cov txheej kom tsis txhob poob dej sai dhau. Kev kho hauv zos tuaj yeem ua los ntawm kev siv tes.
