2. Zoo dua Load Distribution Capacity, txo qhov kev pheej hmoo ntawm kev puas tsuaj hauv zos
The dense inorganic crystalline structure and fiber-reinforced layer (eg, glass fibers) of MgO boards can evenly transfer localized concentrated loads (such as pressure from furniture bases or small equipment feet) to the base layer (eg, floor concrete, ceiling keels). Qhov no zam cov txheej txheej hauv qab kev puas tsuaj los ntawm "kev ntxhov siab hauv zos".
Piv txwv li, thaum pw hauv pem teb hauv chav nyob, yog tias lub rooj zaum ceg (nrog rau thaj chaw me me thiab qhov hnyav ntawm kwv yees li 8kg) raug nias ncaj qha rau ntawm plywood underlayer, nws yuav ua rau muaj kev nyuaj siab hauv zos hauv plywood. Txawm li cas los xij, MgO board underlayer tuaj yeem cuam tshuam lub siab mus rau thaj tsam ib puag ncig ntawm 30cm, kom ntseeg tau tias muaj zog ntau dua ntawm lub hauv paus pob zeb thiab tshem tawm txoj kev pheej hmoo ntawm kev nyuaj siab.

1. Cov dej noo zoo heev thiab kev tiv thaiv dej: thaiv dej nkag thiab nthuav dav
The microstructure of MgO boards consists of a dense inorganic crystal network, making it difficult for water molecules to penetrate through pores. Lub caij no, siab - zoo MgO boards txo qhov kev pheej hmoo ntawm kev nqus dej ntawm qhov chaw los ntawm "tsawg- chloride formulations" (txo cov ntsiab lus tsis muaj magnesium chloride) thiab "siab-kub curing txheej txheem" (txhim kho board compactness):
Cov ntaub ntawv ntsuam xyuas qhia tau hais tias raws li MgO boards muaj 24-teev dej nqus tus nqi tsawg dua lossis sib npaug li 15% thiab qhov ntim nthuav dav tsawg dua lossis sib npaug li 2% tom qab nqus dej- qis dua li ntawm cov plywood (tshaj 10% expansion rate) thiab gypsum boards (dhau 2%). Txawm tias nyob rau lub sij hawm ntev "dej da dej + ntxuav cov dej sib tov" hauv chav dej, cov laug cam yuav tsis soften, delaminate, los yog bulge rau saum npoo. Lawv muaj peev xwm tswj tau qhov flatness ntawm lub hauv paus txheej thiab tiv thaiv tom qab tawg ntawm ceramic vuas los yog waterproof membranes.
2. Inorganic Composition Resistant Mildew thiab Kab Kab Kab Tsuag: Tshem tawm cov phom sij hauv qhov chaw ntub dej
Cov av noo siab hauv chav dej yooj yim ua rau cov pa roj carbon monoxide (piv txwv li, plywood, nruab nrab- ntom fiberboards) kom loj hlob mildew thiab nyiam borers. Qhov no tsis tsuas yog cuam tshuam rau kev nyiam huv, tab sis kuj txo lub zog ntawm lub rooj tsavxwm vim muaj pwm. Nyob rau hauv sib piv, MgO boards yog tsim los ntawm magnesium oxide (ib qho inorganic ntxhia), ntxiv nrog inorganic fibers (xws li, iav fibers), thiab tsis muaj ntoo fibers los yog organic resins:
Cov ntaub ntawv inorganic lawv tus kheej tsis muab "cov khoom noj khoom haus" xav tau rau kev loj hlob mildew, yog li tsis muaj kev pheej hmoo ntawm mildew nyob rau hauv qhov chaw ntub dej. Nyob rau tib lub sijhawm, qhov tsis muaj cov khoom siv ntoo ua tiav tiv thaiv kev kis kab mob los ntawm kab tsuag, ntoo -cov kab tho txawv, thiab lwm yam. Cov txheej txheem kev ncaj ncees tuaj yeem khaws cia rau lub sijhawm ntev - siv, tshem tawm qhov xav tau ntau zaus hloov thiab tu.
3. Kev sib raug zoo nrog cov dej tsis zoo: Txhim kho cov dej noo tag nrho -Cov nyhuv pov thawj
Lub hauv paus txheej ntawm chav dej yuav tsum tau ua hauj lwm nrog waterproof membranes thiab coatings los ua ib tug "ntau- txheej ya raws- pov thawj barrier". MgO board underlayer gaskets pom zoo heev compatibility nyob rau hauv no system:
Lawv muaj kev hloov pauv tau zoo nrog cov ntaub ntawv tsis muaj dej tsis zoo (xws li cov cement-raws li capillary crystalline waterproof coatings, polymer cement waterproof mortars). Ob leeg yog cov ntaub ntawv inorganic nrog zoo sib xws expansion coefficients, ua kom ruaj khov tsis muaj kev cuam tshuam kev cuam tshuam. Qhov no ua rau muaj kev sib xyaw ua ke ntawm cov dej noo-cov qauv pov thawj ntawm "underlayment + waterproof layer";
Txawm tias thaum ua ke nrog cov organic waterproof coatings (xws li, polyurethane coatings), alkalinity ntawm MgO board nto (pH 8-10) tsis hnov mob chemically nrog cov txheej. Tsis tas li ntawd, lub rooj tsavxwm saum npoo yog tiaj tus (nrog me ntsis roughness), kom ntseeg tau tias cov ntaub ntawv tsis sib xws ntawm cov txheej txheem dej tsis zoo thiab tsis txhob muaj cov ntsiab lus tsis muaj dej tsis zoo los ntawm cov txheej txheem tsis sib xws.
