Hluav taws kub ntsuas ntawm Magnesium Oxide Board Fireproof Qab nthab
Qhov ntsuas hluav taws kub tseem ceeb ntawm magnesium oxide board fireproof qab nthab yog uniformlyClass A uas tsis yog{0}}combustible, uas yog nws qhov tseem ceeb kom zoo dua li lub qab nthab fireproof. Cov ntsiab lus tshwj xeeb yog raws li hauv qab no:
Core Fire Rating: Class A Tsis yog -Combustible (Tsuas yog Mainstream Rating)
Raws li lub teb chaws tus qauvGB 8624-2012 "Kev faib tawm ntawm Kev Ua Haujlwm Kub Kub ntawm Cov Khoom Siv Hauv Tsev thiab Cov Khoom", qhov ntsuas hluav taws kub ntawm magnesium oxide board fireproof qab nthab yogChav Kawm A.
Chav A yog ntxiv rau hauv chav A1 (tsis yog- cov khoom siv hluav taws xob) thiab Chav A2 (tsis yog- cov khoom siv hluav taws xob nrog cov pa taws me me). Raws li magnesium oxide boards ntawm kev ua lag luam tuaj yeem ncav cuag Chav Kawm A1 lossis A2, ob qho tib si koom nrog hauv qeb ntawm "tsis yog- cov khoom siv hluav taws xob".
Cov txheej txheem tseem ceeb rau kev txiav txim siab ntsuas: Tsis muaj kev sib tsoo lossis cov pa roj toxic tso tawm thaum raug hluav taws kub, nrog rau qhov hluav taws kub txwv feem ntau ntau dua lossis sib npaug li 0.5 teev (nyob ntawm lub thickness ntawm lub rooj tsavxwm thiab txoj kev teeb tsa).
Vim Li Cas Tsis Muaj Lwm Qhov Kev Ntsuas?
Lub hauv paus khoom ntawm magnesium oxide board yog inorganic minerals xws li magnesium oxide thiab magnesium chloride, uas yog ib txwm tsis -combustible thiab tsis tuaj yeem ncav cuag qis qis xws li Class B1 ( nplaim taws - retardant) lossis Class B2 (combustible).
Kev lag luam ua tsis tau raws li "magnesium oxide fireproof board" hais txog Class A uas tsis yog -cov khoom siv hluav taws xob. Cov khoom lag luam uas cim tsis yog-Class A yog qhov yuav ua tsis tau zoo lossis cuav, ua tsis tau raws li lub hom phiaj tseem ceeb ntawm lub qab nthab.
Cov Ntsiab Lus Tshawb Fawb
Thov tus tub lag luam muab ibhom ntawv tshuaj xyuas rau hluav taws- cov khoom sib ntaus sib tua, qhia meej txog qhov kev ntsuas kev ua tau zoo li "Class A1" lossis "Class A2".
Daim ntawv tshaj tawm yuav tsum tau muab los ntawm ib lub koom haum thib peb uas tsim nyog - tog neeg xeem thiab nyob rau hauv lub sij hawm siv tau; cov lus cog tseg yuav tsum tsis txhob ntseeg.
Hluav taws kub ntsuas ntawm Magnesium Oxide Board Fireproof Qab nthab
Cov dej noo- pov thawj kev ua tau zoo ntawm magnesium oxide board fireproof qab nthab yogzoo heev, uas yog ib qho ntawm nws cov txiaj ntsig tseem ceeb, tsim nyog rau feem ntau qhov chaw ntub dej. Cov ntsiab lus tshwj xeeb yog raws li hauv qab no:
Core Indicators of Moisture-Proof Performance
Kev nqus dej tsawg dua lossis sib npaug li 10% (raws li cov qauv kev lag luam), qis dua li cov ntoo ib txwm siv -raws li cov vaj huam sib luag (feem ntau nrog cov dej nqus dej ntau dua 20%).
Tsis muaj mildew, deformation los yog hmoov nyob rau hauv ib puag ncig ntub. Txawm tias siv nyob rau hauv cov xwm txheej nrog cov av noo ntau dua los yog sib npaug li 80% xws li chav dej thiab cov chaw nres tsheb hauv av rau lub sijhawm ntev, nws tuaj yeem tswj cov qauv kev ruaj ntseg.
Kev ntsuas dej tsis kam nce mus txog "Class Ⅱ" (qib dej tsis kam rau cov vaj huam sib luag), ua tau raws li cov kev xav tau ntawm kev siv lub sijhawm ntev - cov av noo los yog luv luv - lub sij hawm tso dej.
Kev Ua Haujlwm Kev Ua Haujlwm ntawm Cov Dej Hiav Txwv-Cov Ntaub Ntawv Pov Thawj
Qhov xwm ntawm cov khoom siv hauv paus tsis nqus dej noo: Cov ntsiab lus tseem ceeb, magnesium oxide thiab magnesium chloride, yog cov ntxhia hauv cov zaub mov tsis muaj hydrophilic pawg thiab yuav tsis nquag nqus dej los ntawm huab cua.
Cov qauv ntom ntom thaiv cov dej vapor: Lub siab - cov txheej txheem tsim cov txheej txheem ua rau muaj qhov porosity tsawg thiab tsis sib xws ntawm lub rooj tsavxwm (1.2-1.5g / cm³), uas tuaj yeem thaiv cov dej vapor nkag mus tau zoo.
Kev hloov kho kev kho kom txo tau efflorescence: High-cov khoom lag luam zoo ntxiv cov tshuaj tiv thaiv- efflorescence cov neeg ua haujlwm kom tsis txhob "moisture rov qab thiab condensation" tshwm sim los ntawm cov khoom seem ntawm magnesium chloride, txhim kho kev hloov mus rau qhov chaw ntub dej.
Moisture-Cov pov thawj ua tau zoo nyob rau hauv ntau yam xwm txheej
Cov chav dej thiab chav ua noj: tuaj yeem siv ncaj qha los ua cov khoom siv qab nthab. Nrog waterproof putty thiab noo noo-cov ntaub ntawv pov thawj, nws yuav tsis mildew lossis bulge tom qab siv ntev -.
Cov chaw nres tsheb hauv av thiab hauv qab daus: tuaj yeem tiv taus qhov yaig ntawm cov dej hauv av, thiab tsis muaj teeb meem xws li board deformation thiab keel rusting.
Yav qab teb rov qab los - mus rau - hnub sab qab teb: Tsis muaj cov tee dej ntau yuav ua rau saum npoo av, thiab tsis muaj dej seem tom qab dampness, yuav tsum tsis muaj dej noo ntxiv - pov thawj kev kho mob.
Kev pov thawj thiab qhov tsis txaus ntshai ntawm kev ya raws -Cov ntaub ntawv pov thawj
Thov kom tus tub lag luam muab ib daim ntawv qhia "board water absorption test report" kom paub meej tias tus nqi ntsuas tsawg dua los yog sib npaug li 10% thiab tsis muaj kev piav qhia ntawm efflorescence lossis frosting.
Kev soj ntsuam zoo: Siab- zoo magnesium oxide boards muaj qhov chaw qhuav tsis muaj nplaum, tsis muaj hmoov ntog los yog xuab zeb ntawm cov npoo, thiab tsis muaj qhov nthuav dav (kev nthuav dav tsawg dua lossis sib npaug li 2%) tom qab 24 teev ntawm kev tso dej.
Kev sib txuam ntawm cov khoom siv pabcuam: Siv kub-dip galvanized keels thiab xeb- pov thawj tus kheej-tapping screws, thiab foob pob qij txha nrog ya raws- pov thawj sib koom ua ke kom tsis txhob keel xeb cuam tshuam rau tag nrho cov dej noo- pov thawj.
Installation Points rau Magnesium Oxide Board Fireproof Qab nthab
1. Kev npaj hauv paus: Ntxuav cov khib nyiab thiab plua plav rau saum npoo kom ntseeg tau tias lub hauv paus tiaj tiaj thiab qhuav; snap kab raws li kev tsim tsa kom txiav txim siab lub keel installation txoj haujlwm.
2. Keel installation: Siv lub teeb steel keels (75-hom lossis 100-hom pom zoo). Qhov sib nrug ntawm lub ntsiab keels Tsawg dua lossis sib npaug ntawm 1200mm, qhov sib txawv ntawm cov pab pawg keels Tsawg dua lossis sib npaug li 600mm, thiab qhov sib txawv ntawm keel kho cov ntsiab lus tsawg dua lossis sib npaug li 800mm los xyuas kom muaj cov ncej ruaj khov.
3. Board txiav: Txiav cov magnesium oxide board nrog lub tshuab txiav raws li lub qab nthab loj, tawm hauv 3-5mm expansion pob qij txha kom tsis txhob tawg vim thermal expansion thiab contraction.
4. Board kho: Kho lub rooj tsavxwm rau keel nrog tus kheej -tapping screws. Cov ntsia hlau sib nrug tsawg dua los yog sib npaug li 200 hli, thiab qhov kev ncua deb ntawm lub taub hau ntsia hlau mus rau lub rooj tsavxwm ntug Zoo dua los yog sib npaug li 15 hli kom tsis txhob ntug chipping; cov pob qij txha ntawm cov laug cam yuav tsum tau ua raws li qhov nruab nrab ntawm lub keel.
5. Kev kho mob sib koom ua ke: Sau cov qhov khoob nrog kev sib koom ua ke tshwj xeeb gypsum, muab cov ntaub mesh los txhim kho qhov adhesion, tom qab ntawd txhuam putty 2-3 zaug tag nrho, thiab polish smoothly ua ntej pleev xim los yog pasting cov ntaub ntawv zoo nkauj.
6. Kev soj ntsuam zaum kawg: Txheeb xyuas qhov flatness thiab firmness ntawm lub qab nthab kom tsis txhob xoob lossis bulging; cov npoo ntawm qhov qhib rau lub teeb thiab cov cua vents yuav tsum du thiab kaw kom zoo.
