Technological innovation is the development of enterprises in the last word , i have always maintained the secretary rise in special wallssevered the forefront of the core system , in 2000 , the high - intensity of my invention cesium potassium glass chip . test success has been on the market seven years , 2007 to special ( fire ) glass wallsindoor fire glass partition , fire glass window design , construction and 10 years of deep - processing glass curtain wall designconstruction and constantly sum up experience and experiment , glass walls severed system to fire . high temperature must be within the framework of anti - bomb material support fixed glass in the event of fire . at the time of the explosion have enough time to ensure the integrity of the entire system . bullet - proof glass or glass does not fire in a short period of time due to damage fixed framework , a glass panel fell off , lost the fire or bomb - functional 企業不斷的技術創新是我們發展的硬道理,也是我司一直保持林立于特種幕墻、隔斷系統前沿的核心, 2000年,我司發明的高強度單片銫鉀防火玻璃,經試驗檢測成功推向市場以來已有7個年頭,七年來特種(防火)玻璃幕墻、室內防火玻璃隔斷、防火玻璃門窗的設計、施工及十多年來的玻璃深加工,幕墻設計、施工及不斷的經驗總結和試驗,玻璃幕墻、隔斷系統要防火、防炸彈沖擊波必須要有耐高溫高強度的框架材料固定支撐玻璃,在一旦發生火災、爆炸的時候要有足夠的時間保證整個系統的完整性,不至于防火玻璃或防炸彈玻璃在短時間內由于固定框架破壞,而玻璃脫落,失去了防火或防炸彈的功能。 |
