                煤礦井下用高強聚酯纖維網
                產品介紹:
                煤礦井下用聚酯纖維增強塑料網假頂是用高模、高強度滌綸長絲捆綁編織成基體,在該基體的表面涂覆一層可阻燃導靜電的涂層,用以代替竹耙、金屬網、塑料網、鋼塑網等傳統支護材料,該產品耐酸堿,不易老化,成本低,使用壽命長,具有強度高、阻燃、導靜電等性能, 可廣泛應用于巷道護頂、護幫及工作假頂。
                產品特點:
                堅固柔軟、重量輕、拉力強度高、每平方米的礦用強度復合網只有1KG左右,同等金屬網的重量則是32KG左右。每平方米的最小拉力強度達40KN,最大拉力強度可達1000KN,同等其它金屬網、鋼塑網等與礦用網強力是無法相比的。
                抗酸堿、耐腐蝕、摩擦不易產生靜電,阻燃性能好,在井下埋壓性能基本不變。金屬網、鋼塑網腐蝕嚴重,大大降低拉力強度。
                應用范圍:
                煤礦井下回采工作面假頂支護工程,煤礦錨噴巷道、隧道的臨時和永久支護,也可用作其他礦山巷道工程、地下土建工程。
                經濟效益:
                通過鋪設煤礦井下用聚酯纖維增強塑料網假頂,提高巷道、圍巖的安全性,避免巷道片幫、漏矸、冒頂現象的發生,改善了巷道的安全條件,減少事故發生;減小巷道的通風阻力,節約能源。煤礦井下用聚酯纖維增強塑料網假頂,在煤礦井下采煤工作面和掘進工作面的臨時支護中,可回收重復使用。
                煤礦井下用聚酯纖維增強塑料網假頂質輕、耐酸堿、成本低、易鋪設。網孔尺寸一般是20*20mm、40*40mm、50*50mm,也可根據客戶需求改變網孔大小。產品顏色一般為米黃色、白色、藍色,也可根據客戶設計要求制作,既減少聯網工作量,又增加煤礦井下用聚酯纖維增強塑料網假頂的整體性能。
                使用方法:
                在煤礦井下支護巷道中,同樣使用金屬網支護工藝要求,可用M型鋼帶和錨盤壓緊高強復合并用螺紋鋼等高強錨桿吊掛和拉緊,煤礦井下用聚酯纖維增強塑料網假頂接頭處,搭接20mm;網與網之間可用14#鐵絲,每隔100-150mm擰緊。在煤礦井錨噴巷永久支護中,也同樣適用于金屬網支護工藝要求,可用錨桿和錨盤固定高強度復合網后,噴射混凝土加強支護,效果更加。在煤礦井下,采煤工作面和挖進工作面的臨時支護中,煤礦井下用聚酯纖維增強塑料網假頂,更優越于其他金屬網,使用簡單、輕便、易折疊、易施工。
