Non-expanding fireproof txheej rau steel qauv
Product Description
Non-expanding steel qauv fireproof txheej yog tsim rau txau rau saum npoo ntawm steel qauv, tsim ib txheej ntawm rwb thaiv tsev kub thiab hluav taws kub tiv thaiv txheej, uas tiv thaiv cov hlau qauv ntawm hluav taws los ntawm kev muab rwb thaiv tsev. Cov txheej tuab ntawm cov khoom siv hluav taws xob yog cov khoom siv hluav taws xob tsis zoo, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, thiab muaj cov yam ntxwv ntawm kev siv yooj yim thiab nrawm, muaj zog txheej adhesion, muaj zog txhua yam, lub sij hawm ntev hluav taws kub, ruaj khov thiab txhim khu kev qha hluav taws, thiab muaj peev xwm tiv taus kev kub ntxhov los ntawm cov nplaim hluav taws kub xws li hydrocarbons. Lub thickness ntawm txheej txheej yog 8-50mm. Cov txheej tsis ua npuas dej thaum rhuab thiab tso siab rau nws cov thermal conductivity kom ntev qhov kub ntawm cov qauv steel thiab ua lub luag haujlwm hauv kev tiv thaiv hluav taws.
siv ntau yam
Non-expanding steel qauv fireproof txheej tsis yog tsuas yog haum rau kev tiv thaiv hluav taws ntawm ntau yam load-bearing steel qauv nyob rau hauv ntau hom tsev xws li high-sawv vaj tse, roj av, tshuaj, fais fab, metallurgy, thiab lub teeb kev lag luam, tab sis kuj muaj feem xyuam rau ib co steel qauv nrog hluav taws kub phom sij tshwm sim los ntawm hydrocarbon chemicals (xws li roj, kuab tshuaj petroleum, hluav taws xob engineering, thiab lwm yam). platforms, thiab kev txhawb nqa thav duab ntawm cov chaw cia roj, thiab lwm yam.

Thaum qhov ntsuas hluav taws kub ua haujlwm ntev li 180 feeb, qhov loj ntawm cov nqaj hlau yog 21 hli, thiab nws tsis poob nws cov kabmob. Qhov hluav taws kub txwv tsis pub tshaj 3.0 teev.
Txoj kev tsim kho
(I) Kev Npaj Ua Ntej Ua Ntej
1. Ua ntej tshuaj tsuag, tshem tawm cov khoom adhering, impurities, thiab plua plav tawm ntawm cov qauv steel nto.
2. Rau steel qauv Cheebtsam nrog xeb, ua xeb tshem tawm kev kho mob thiab siv cov tshuaj tiv thaiv xeb (xaiv cov tshuaj tiv thaiv xeb uas muaj zog adhesion). Tsis txhob tsuag kom txog thaum cov xim qhuav.
3. Kev tsim kho ib puag ncig kub yuav tsum siab tshaj 3 ℃.
(II) Kev Txhaj Tshuaj
1. Kev sib xyaw ntawm cov txheej txheem yuav tsum tau ua nruj me ntsis 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 tso rau hauv lub tov khoom rau 3-5 feeb, tom qab ntawd ntxiv cov khoom siv hmoov thiab sib tov kom txog thaum qhov tsim nyog sib xws.
2. Siv cov khoom siv tshuaj tsuag rau kev tsim kho, xws li cov tshuab txau, cov tshuab cua compressors, cov khoom thoob, thiab lwm yam; daim ntawv thov cov cuab yeej xws li mortar mixers, cov cuab yeej rau plastering, trowels, cov khoom thoob, thiab lwm yam. Thaum lub sij hawm siv tshuaj tsuag, lub thickness ntawm txhua txheej txheej yuav tsum yog 2-8 hli, thiab lub sij hawm tsim kho yuav tsum yog 8 teev. Lub sijhawm tsim kho yuav tsum raug kho kom tsim nyog thaum qhov kub thiab av noo sib txawv. Thaum lub sij hawm txheej txheej txheej thiab 24 teev tom qab kev tsim kho, qhov kub ntawm ib puag ncig yuav tsum tsis txhob qis dua 4 ℃ los tiv thaiv Frost puas; nyob rau hauv qhuav thiab kub tej yam kev mob, nws yog advisable los tsim ib tug tsim nyog tu tej yam kev mob los tiv thaiv lub txheej los ntawm poob dej sai heev. Kev kho hauv zos tuaj yeem ua los ntawm tes thov.
Lus Ceeb Toom
- 1. Cov khoom tseem ceeb ntawm sab nraum zoov tuab-hom steel qauv fireproof txheej yog ntim rau hauv cov hnab yas qis uas muaj cov hnab yas, thaum cov khoom siv pabcuam tau ntim rau hauv nruas. Kev khaws cia thiab kev thauj mus los kub yuav tsum tsis pub dhau 3 - 40 ℃. Nws tsis raug tso cai khaws cia sab nraum zoov lossis raug tshav ntuj.
- 2. Cov tshuaj txau yuav tsum tau tiv thaiv los ntawm nag.
- 3. Lub sijhawm khaws cia zoo ntawm cov khoom yog 6 lub hlis.
