Yuav ua li cas MGO Board rau Phab Ntsa Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Magnesium Oxide Board MGO Vaj Huam Sib Luag Ua Haujlwm Li Cas?
MGO Board (Magnesium Oxide Board) attains lubChav kawm A1 tsis yog- qhov ntsuas hluav taws kub(GB 8624-2012) los ntawm peb-dimensional mechanism uas muajinorganic puag cov khoom siv, kev tsim qauv, thiab cov txheej txheem optimization. Nws qhov hluav taws kub- txoj cai tiv thaiv tau piav qhia hauv 5 yam tseem ceeb hauv qab no:
1. Core: Qhov "Tsis yog-Txoj Kev Teeb Meem" ntawm Inorganic Mineral Base Material
Lub ntsiab Cheebtsam ntawm MGO Board tsim ib tug inorganic cementitious system: ib tug ternary sib tov ntawmmagnesium oxide (MgO), magnesium sulfate (MgSO₄), dej, ntxiv nrog inorganic fillers (xws li, talc, quartz xuab zeb) thiab ntxiv dag zog nrog nruab nrab -alkaline iav fiber mesh. Tsis muaj cov organic combustible Cheebtsam koom nrog:
Magnesium oxide (MgO), ib yam khoom ntawm ntuj ntxhia calcination, yog incombustible inorganic tshuaj nrog ib tug melting point ntawm 2852 degree. Nws tsis muaj thermal decomposition lossis melting hauv qab 800℃thiab tsis tso cov pa hluav taws xob thaum raug hluav taws.
Magnesium sulfate (MgSO₄), ua raws li tus neeg sawv cev kho, kuj yog incombustible, siab - kub- resistant inorganic compound. Nws reacts nrog magnesium oxide los tsim ib tug ruaj khov crystalline qauv ntawm "5·1·8 theem magnesium ntsev cement," ntxiv dag zog rau qhov hluav taws kub stability ntawm lub hauv paus khoom.
Muab piv rau cov ntoo-raws li cov vaj huam sib luag (flammable organic fibers) thiab gypsum boards (yuav ua rau lub cev qhuav dej thiab hmoov av ntawm qhov kub siab), MGO Board cov khoom siv tsis zoo hauv cov khoom siv hauv paus tshem tawm "roj qhov chaw." Nws tsuas yog me ntsis shrinks thaum raug hluav taws kub, tsis muaj hluav taws kub lossis tawg.
2. Cov qauv: "Cov Hluav Taws Xob Hluav Taws Xob" Txhim kho los ntawm iav fiber ntau mesh & ntom ntom ntom
(1) Skeletal Support of Neutral-Alkaline iav Fiber Mesh
MGO Board yog embedded nrog ntau txheej ntawm nruab nrab-alkaline iav fiber ntau mesh, uas nws lub ntsiab yog silicon dioxide (SiO₂)-ib inorganic siab- kub- resistant khoom nrog ib tug melting point ntawm kwv yees li 1720℃. Nws tseem incombustible, tsis yog-softening, thiab tsis-shrinking ntawm kub kub. Nws cov haujlwm muaj xws li:
Txhim khu kev ncaj ncees: Txawm hais tias cov khoom siv hauv paus me ntsis qis thaum lub sij hawm hluav taws kub, cov iav fiber ntau tuav cov pob txha pob txha, tiv thaiv lub rooj tsavxwm los ntawm kev tawg thiab poob tawm thiab ua kom muaj hluav taws kub nyhiab.
Thaiv cov nplaim hluav taws xob nkag mus: Cov txheej txheem ntom ntom ntawm cov iav fiber ntau cuam tshuam cov nplaim hluav taws sib kis thiab ncua kev nkag mus rau hluav taws. Thaum ua ke nrog keel system, nws ntxiv txhim kho qhov ntsuas hluav taws xob (piv txwv li, muab faib ua ob npaug - txheej 9 hli MGO boards + 75mm keels + pob zeb wool ua tiav qhov ntsuas hluav taws kub ntau dua 3 teev).
(2) Nthuav Thermal rwb thaiv tsev txheej ntawm High-Pressure Molding
MGO Board yog tsim los ntawm "siab-siab molding + siab-kub curing," uas ua rau lub rooj tsavxwm tsis sib xws (density: 0.8-1.2g/cm³):
Cov qauv ntom ntom txo cov cua qhov pores, txo cov thermal conductivity (tsuas yog 0.11-0.15W / (m·K)) thiab muab cov thermal rwb thaiv tsev zoo, tiv thaiv kom kub hloov mus rau sab nraub qaum.
Thaum lub sij hawm hluav taws kub, lub rooj tsavxwm nto tsim ib qho "ceramicized glaze" (ib yam khoom ntawm siab -kub sintering ntawm inorganic Cheebtsam), uas txuas ntxiv qhov hws, thaiv cov pa oxygen, thiab cuam tshuam cov saw hlau combustion.
3. Cov tshuaj tiv thaiv: "Stabilization Transformation" ntawm qhov kub thiab txias
Thaum raug kub los yog nplaim taws, MGO Board tsis muaj "combustion reaction" -tsuas yog hloov lub cev me ntsis- yam tsis tso cov tshuaj phem:
Tsis muaj thermal decomposition: Cov qauv crystalline ntawm magnesium ntsev cement (5·1·8 theem) tsim los ntawm magnesium oxide thiab magnesium sulfate tseem nyob ruaj khov hauv qab 1200 degree, tsis decomposing rau hauv nplaim taws / toxic gases xws li CO, formaldehyde, los yog benzene.
Tsis muaj molten dripping: Tsis zoo li cov organic panels (xws li, PVC boards) uas yaj thiab drips ntawm qhov kub thiab txias, MGO Board tsuas yog shrinks maj mam thiab me ntsis hmoov rau ntawm qhov chaw, tsis muaj drippings ua rau lwm yam hluav taws kub.
Haus luam yeeb-dawb & tsis yog- tshuaj lom: Tsis muaj cov organic additives, asbestos, thiab cov xov tooj cua, nws ua tsis muaj pa luam yeeb thaum hlawv, ua tau raws li European thiab Asmeskas "tsim pa taws- cov khoom siv hauv tsev dawb" thiab muab sijhawm khiav tawm ntau dua.
4. Txheej txheem: Hloov kho kom zoo "Fire Stability"
Ob txheej txheem tseem ceeb optimizations ntxiv dag zog tiv thaiv hluav taws thaum tsim khoom:
Halide Efflorescence Resistance Hloov Kho: Cov kev hloov kho tshwj xeeb (piv txwv li, phosphate esters, silicone) yog ntxiv los tiv thaiv "halide efflorescence" ( nag lossis daus ntawm magnesium sulfate ) nyob rau hauv qhov chaw ntub dej, ua kom muaj kev ruaj ntseg ntawm cov txheej txheem inorganic cementitious. Efflorescence yuav loosen lub board qauv thiab txo cov hluav taws kev cia siab rau ntawm qhov kub thiab txias.
Gradient Density Design: High-kawg MGO Boards txais cov qauv gradient ntawm "dense surface + uniform core." Qhov saum npoo sai sai tsim cov txheej txheem tiv thaiv ceramic, thaum lub hauv paus tseem muaj lub zog ntawm cov qauv, ncua sijhawm hluav taws kub.
5. Kev sib piv: Qhov sib txawv ntawm qhov tseem ceeb ntawm Cov Hluav Taws Xob Hluav Taws Xob -Resistant Panels
