Damp pov thawj: Muaj feem xyuam rau txhua qhov chaw noo noo
MgO boards yog cov khoom siv cua coagulable gel, uas feem ntau muaj cov dej tsis zoo.Txawm li cas los xij, los ntawm peb cov kev hloov kho thev naus laus zis, MgO boards nthuav tawm cov dej tsis zoo.Tom qab 180 hnub ntawm immersion, lawv softening coefficient tseem nyob saum 0.90, nrog ib tug ruaj khov ntawm 0.95 thiab 0.99 thaum lub sij hawm tsis tu ncua kev ntsuam xyuas.Lawv solubility hauv dej yog li 0.03g / 100g dej (gypsum yog 0.2g / 100g dej; sulfoaluminate cement yog 0.029g / 100g dej; Portland cement yog 0.084g / 100g dej).MgO boards 'dej tsis kam yog qhov zoo dua li gypsum, thiab lawv tau sib npaug nrog Portland cement thiab sulfoaluminate cement, ua tau raws li qhov yuav tsum tau siv rau hauv qhov chaw ntub dej.
Daim ntawv thov Scenario
Cov chav dej thiab chav ua noj:MgO boards ua tau zoo tshwj xeeb hauv cov av noo ib puag ncig, ua rau lawv zoo tagnrho rau siv hauv chav dej thiab chav ua noj.Cov chaw no feem ntau raug dej thiab chav dej, thiab MgO boards 'siab dej tsis kam ua kom lub sij hawm ntev thiab ruaj khov hauv cov chaw no.
Hauv qab daus thiab cellars: Hauv qab daus thiab cellars feem ntau cuam tshuam los ntawm ya raws thiab dampness vim lawv nyob ze rau hauv av.MgO boards 'cov khoom tsis muaj dej tsis zoo ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov cheeb tsam no, tiv thaiv kom tsis txhob ya raws thiab tswj kev ua haujlwm zoo.
Sab nrauv phab ntsa thiab ru tsev: Cov yam ntxwv dej tsis zoo ntawm MgO boards ua rau lawv tsim nyog rau sab nrauv phab ntsa thiab ru tsev, tiv thaiv los nag thiab noo noo, thiab ua kom muaj kev nyab xeeb ntawm cov tsev.
Acid & Alkali Resistance ntawm MgO Boards
Acid & Alkali Resistant:Muaj feem xyuam rau High Corrosive Ib puag ncig
Tom qab soaked nyob rau hauv 31% magnesium chloride acid tov rau 180 hnub, lub compressive zog ntawm MgO boards nce los ntawm 80MPa mus rau 96MPa, nrog ib tug zog nce ntawm 18%, uas ua rau corrosion kuj coefficient ntawm 1.19.Nyob rau hauv kev sib piv, cov corrosion kuj coefficient ntawm zoo tib yam Portland cement tsuas yog hais txog 0.6.MgO boards 'kev tiv thaiv corrosion yog qhov siab dua li cov khoom siv cement zoo tib yam, ua rau lawv zoo heev rau kev siv ntsev thiab corrosive ib puag ncig, muab kev tiv thaiv corrosion zoo.
Daim ntawv thov Scenario
Seaside Buildings:MgO boards ua tau zoo heev nyob rau hauv ib puag ncig ntsev siab, ua rau lawv zoo tagnrho rau cov vaj tsev hauv hiav txwv.Cov ntsev tuaj yeem ua rau cov khoom siv hauv tsev zoo heev, tab sis MgO boards ' ntsev tsis kam ua kom muaj kev ruaj ntseg ntev hauv cov cheeb tsam no.
Cov nroj tsuag tshuaj thiab cov chaw soj nstuam: Nyob rau hauv cov cheeb tsam siab corrosive, MgO boards 'cov kua qaub thiab alkali tsis kam muab kev tiv thaiv zoo, ua kom cov khoom siv tsis raug puas los ntawm cov tshuaj lom neeg.
Cov Khoom Siv Ua Lag Luam: MgO boards yog tsim rau ntau yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv nruab nrab corrosive heev, muab kev tiv thaiv txhim khu kev qha thiab ua haujlwm ntev.
Xaus
Cov dej tsis zoo, tsis muaj dej tsis kam, thiab cov kua qaub & alkali tsis kam ntawm MgO boards ua rau lawv tseem ceeb hauv kev tsim kho niaj hnub no.Txawm hais tias nyob rau hauv qhov chaw ntub dej lossis qhov chaw corrosive siab, MgO boards muab kev tiv thaiv tshwj xeeb, ua kom muaj kev ruaj ntseg ntev thiab kev nyab xeeb ntawm cov tsev.
