Magnesium oxide board (feem ntau hu ua "magnesium board") yog ib hom tshiab ntawm cov khoom siv hauv tsev. Nws yog tsim los siv magnesium oxide thiab magnesium chloride ua cov ntaub ntawv tseem ceeb, sib xyaw nrog cov ntsiab lus tshwj xeeb ntawm perlite, fiberglass mesh, ntoo fiber ntau, thiab lwm yam khoom ntxiv. Nws nta cov khoom xws li ua lub teeb yuag, hluav taws kub, muaj zog, lub suab-nqus, thiab kub-insulating, thaum tseem tsis muaj tshuaj lom, corrosion-resistant, thiab pwm-resistant. Nws yog tsim rau siv nyob rau hauv cov phab ntsa, suspended ceilings, thiab li flooring underlayment.
Iav-magnesium board yog dav siv rau sab hauv partitions thiab qab nthab hauv tsev so, khw malls, tsev noj mov, nightclubs, tsev txhab nyiaj, tsev kho mob, supermarkets, chaw ua hauj lwm cov tsev, thiab cov tsev nyob. Nws yog qhov tsim nyog rau cov ntawv thov uas muaj cov txheej txheem thermal rwb thaiv tsev, cov phab ntsa tsis muaj suab nrov, cov khoom siv txav tau yooj yim, qib siab fireproofing, hluav taws-qhov rooj cores, thiab cov khoom siv casing.
Cia
Thaum lub board fireproof yog huab cua-resistant, nws raug nquahu kom khaws cia rau hauv tsev kom ntseeg tau tias nws tseem qhuav thaum siv; qhov chaw cia yuav tsum yog theem lossis lined nrog ntoo planks.
Kev ua haujlwm
Lub rooj tsavxwm tuaj yeem txiav tau siv lub tes taw lossis hluav taws xob pom, lossis tau qhab nia thiab snapped siv riam siv hluav taws xob thiab ncaj. Nws tuaj yeem txuas nrog cov ntsia hlau, ntsia hlau rau tus kheej, lossis rab phom ntsia hlau, lossis los ntawm qhov ua ntej tho qhov.
Ua tiav
Lub board nto tuaj yeem ua tiav nrog cov ntawv ntsa, beech ntoo veneer, xim, vuas, lossis mosaics.
Lus Cim: Thaum thov cov vuas los yog mosaics, ntxiv dag zog rau lub board nto nrog ib tug hlau hlau mesh. Siv lub hauv paus txheej ntawm cov cement mortar ua ntej adhering cov vuas.
Phab ntsa
(1) Board: Feem ntau, nws raug nquahu kom siv iav-magnesium board nrog lub thickness ntawm 6 hli los yog ntau dua rau kev faib phab ntsa.
(2) Accessories: Thaum fastening boards (6mm los yog thicker) rau cov framing studs (furring channels), siv 3.5mm x 20mm countersunk screws. Lub taub hau ntsia hlau yuav tsum yog countersunk 0.5mm hauv qab ntawm lub rooj tsavxwm saum npoo kom ntseeg tau tias ua tiav.
(3) Kev teeb tsa: Ua ntej kev teeb tsa pib, kos cov haujlwm ntawm cov studs kom raug. Qhov nruab nrab-rau-nruab nrab qhov sib nrug ntawm ntsug studs yuav tsum yog 450-600 mm. Ntxiv studs yuav tsum tau ntsia rau ntawm phab ntsa junctions thiab ntawm ob sab ntawm lub qhov rooj thiab qhov rais qhib; yog tias phab ntsa qhov siab tshaj 2440 hli, yuav tsum muaj kev txhawb nqa ntxiv ntawm cov pob qij txha.
(4) Board qhov sib nrug: Cia qhov sib txawv ntawm 4-6 hli ntawm cov boards uas nyob ib sab thiab 5 hli qhov sib txawv ntawm lub rooj tsavxwm thiab hauv pem teb. Cov ntsia hlau sib nrug yuav tsum yog 150 hli ntawm qhov nruab nrab, nrog cov ntsia hlau tso 10 hli ntawm lub rooj tsavxwm ntug thiab 30 hli los ntawm lub ces kaum.
(5) Hanging loads: Cov cheeb tsam npaj rau dai cov khoom hnyav hauv chav dej lossis chav ua noj yuav tsum tau ntxiv nrog cov ntoo rov qab lossis cov studs ntxiv los tiv thaiv kev puas tsuaj rau cov laug cam.
(6) Kev kho kev sib koom ua ke: Khaws qhov sib txawv ntawm 4-6 hli ntawm cov laug cam thaum lub sijhawm teeb tsa. Siv ib qho sib tov ntawm 107 nplaum los yog lub zog nplaum nplaum rau ntawm cov npoo ntawm lub rooj tsavxwm thiab qhov khoob uas siv rab riam, ces siv daim kab xev los yog fiberglass mesh daim kab xev thiab nias nws tiaj.
(7) Txheej / Tiav: Txau, txhuam, los yog dov txoj kev yuav siv tau; Txawm li cas los xij, thaum txhuam hniav, thov saib cov lus qhia tshwj xeeb uas muab los ntawm cov chaw tsim khoom txheej.
(8) Tiling: Thaum txhim kho hauv qhov chaw ntub dej xws li chav dej, chav ntxhua khaub ncaws, chav ua noj, lossis hauv qab daus, qhov sib nrug ntawm qhov yuav tsum tau txo mus rau 400 hli yog tias yuav tsum tau tiling. Ib qho kev nthuav dav yuav tsum tau muab rau txhua peb lub rooj tsav xwm (kwv yees li 3.6 meters) raws phab ntsa.
(9) Lub suab rwb thaiv tsev phab ntsa: Rau lub suab rwb thaiv tsev zoo, xyuas kom nruj, airtight foob ntawm phab ntsa qauv thiab cov laug cam, thiab sau cov phab ntsa kab noj hniav nrog cov ntxhia wool. Siv cov laug cam sib txawv ntawm ob sab ntawm cov studs tuaj yeem txhim kho suab rwb thaiv tsev.
(10) Impact-resistant phab ntsa: Nws raug nquahu kom siv cov boards tuab dua 8 hli los yog txhawm rau txhim kho cov txheej txheem ntxiv (siv cov ntsia hlau ntev dua los tiv thaiv txheej thib ob). Txoj kev no txhim kho kev cuam tshuam kev tiv thaiv, thermal rwb thaiv tsev, suab rwb thaiv tsev, thiab hluav taws kub.
Qab nthab
(1) Feem ntau, nws raug pom zoo kom siv cov laug cam nrog lub thickness ntawm 6 hli los yog ntau dua rau cov qab nthab.
(2) Thaum tuav cov laug cam, pib fastening los ntawm qhov chaw thiab ua hauj lwm sab nraud rau cov npoo.
