Fire-resistant fiber cement composite steel plates, as a new type of high-performance building material, adopt a sandwich composite structure of "galvanized steel plate + fiber cement core layer," formed by high-temperature and high-pressure processes. Steel hte fiber cement lahkawng yan a akyu ara ni hpe kahkyin gumdin nna, shim lum lam makawp maga ai lam, jak rung atsam ni, grup yin hpe htuk manu hkra galaw lu ai atsam ni hta grau kaja ai atsam ni hpe madun dan nna, hkrit tsang hpa kaba ai hpaga lam hte mung shawa nta ni hta grai lang ai.
Grai sawng ai wan hte bawm kapaw ai lam hpe ninghkap lu ai atsam gaw shi a madung arawn alai rai nga ai. Ndai arung arai gaw A1 non-wan hkru ai madang hpe hkan sa nna, wan hpe hkying hkum 4 kaw nna 6 du hkra hkam sharang lu ai. 1770–2000℃nbung katsi ai shara hta npawt nhpang hpe makawp maga ya nna, masha ni hpe htawt sit ai hte wan hkru ai lam ni hpe hkye la na matu manu dan ai aten hpe mari la ya ai. Shi a bawm kapaw ai-hkap la lu ai atsam gaw grau nna dan dawng nga ai; fiber cement core layer gaw hkrat sum ai n-gun hpe atsawm sha hkap la nna, bawm kapaw ai n-gun wave ni hpe bra ayai shangun ai, 3000KPa hta grau ai (sh) dai hte maren ai bawm kapaw ai n-gun hpe hkam sharang lu ai. Hkrum hkra ai hpang, n-gun ja ai daw ni hpe n shapraw ya ai majaw, lahkawng lang ngu na hkala nba byin wa na hpe hkrak sha shayawm ya lu ai majaw, chemical plant ni hte sau htu ai shara ni zawn re ai -hkrit tsang hpa law ai shara ni a matu htuk manu ai.
N-gun n law ai hte -n-gun ja ai jak rung atsam ni gaw shim lum lam hte shim lum lam hpe kahkyin gumdin ya ai. Dai plate a n-gun gaw 2.2-2.8 g/cm3 daram rai nna, shinggyim masha ni lang ai n-gang plate ni hta na htam masum hta na htam mi daram sha rai nga ai. 9.5mm galu ai plate langai gaw square meter mi hta 23-25kg sha hkam ai majaw masha langai sha lang na matu loi ai. Dai hte maren, grai kaja ai jak n-gun hpe gumrawng nga ai, 185MPa hta grau kaba ai (sh) dai hte maren sha n-gun rawng ai hte 72GPa hta jan ai elastic modulus nga ai. 1m tsaw ai kaw nna hkrat wa ai 4.5kg hkam sharang ai arai hpe hkam sharang lu ai, hkrat sum ai n-gun hpe 2700J du hkra hkam sharang lu ai, lit hkam ai npawt nhpang ni a ra kadawn ai lam ni hpe hkap la lu ai sha n-ga, n-gun shayawm ai hte n-gun shayawm ai hpe mung hkam sharang lu ai.
Laksan grup yin hpe htuk manu hkra galaw lu ai atsam gaw aten galu-hpring tsup hkra galaw ya ai. Dai arai gaw, nbung katsi ai shara law law hta ngang grin ai bungli galaw ai lam hpe madun dan nna, -40℃kaw nna 600℃du hkra grai sawng ai makau grup yin ni hta pyi, n-gun n rawng ai hte n-gun n rawng ai hpe hkam sharang lu ai majaw, katsi katsang re ai dingdung daw na nbung laru hte nbung laru kaba ai bungli galaw ai shara ni a matu htuk manu nga ai. Galvanized steel ntsa gaw grai kaja ai n-gun hte hka lim ai hpe hkam sharang lu ai majaw, hkying hkum 2000 jan na hkra hka lim ai chyam dinglik ai lam hpe lu la ai. Acid, alkali, carbon compound ni a n-gun hpe ninghkap lu ai, hka n-gun 10% hta n-pu (sh) maren sha nga ai majaw, ga npu na shara ni hte sanghpaw li ni zawn re ai hka n-gun rawng ai shara ni hta htuk manu ai. Shaning 30 jan na hkra galaw lu ai ngu gumrawng nna, gram lajang ai lam n ra ai ngu tsun mai ai.
Dai board ni a galu kaba ai lam gaw 1200mm×2400mm (sh) 1220mm×2440mm rai nga ai. Dai gaw, htu ai, htu ai, katsi ai hku shinggrup ai zawn re ai galaw ai ladat amyu myu hpe madi shadaw ya nna, size hte maren gram lajang mai ai. Modular hpe jung ai gaw, gawgap ai aten hpe grai kadun shangun ai. Ndai arung arai gaw asbestos-n lawm ai hte formaldehyde n law ai majaw, hkai sun hte grup yin hpe makawp maga ai nta gawgap ai arung arai langai mi rai nga ai. Shi a tsaw ai ntsa nsam nsam gaw, n-gun n rawng ai sha, hkrak sha mawn sumli lu ai, nsen- hpe hkap la lu ai atsam mung nga ai, grup yin na nsen hpe atsawm sha shayawm ya lu nna, shim lum lam hte tatut galaw mai ai lam lahkawng yan hpe lu la mai ai.
