服務詳情

中國是世界生產和使用石材幕墻的大國。據不完全統計,國內年均石材裝飾板材用于墻面裝飾的約 2500萬平方米左右,所用石材幕墻掛件約1.4億套左右。石材幕墻已在國內呈上升趨勢,掛件的用量也隨之增大,如今業內最為關心的問題就是掛件的質量,雖然在整個石材幕墻中掛件只是一個小小的配件,但它卻起著四兩拔千斤的作用,也可以說在整個石材幕墻的質量與安全問題中掛件是最關鍵的配件之一。

1.天然材質、光亮晶瑩、堅硬永久、高貴典雅

2.耐凍性:石材在潮濕狀態下,能抵抗凍融而不發生顯著之破壞者,此性能稱為耐凍性。巖石孔隙內的水份在溫度低到攝氏零下20時,發生凍結,孔隙內水份膨脹比原有體積大1/10,巖石若不能抵抗此種膨脹所產生的力量,便會出現破壞現象。

3.抗壓強度:石材的抗壓強度會因礦物成份、結晶粗細、膠結物質的均勻性、荷重面積、荷重作用與解理所成角度等因素,而有所不同。若其他條件相同,通常結晶顆粒細小而彼此粘結一起的致密材料,具有較高強度
