新近在瓦楞铁板、铝合金波形瓦、加筋石棉瓦之外又发展了一种可以代替普通水泥石棉瓦的围护材料——玻璃钢加强石棉中波瓦,现已在一些工程的屋盖和墙面上使用。这是一种以普通水泥石棉瓦为底胎,上覆单层玻璃纤维布、聚酯树脂玻璃钢的复合构件。受力性能好、吸水率低,具有较好的抗冲击、防腐蚀和耐候、防水性能。根据试验,该瓦的横向抗折力为335公斤,分别为
Recently, in addition to corrugated iron, aluminum alloy tile, and reinforced asbestos, a new type of enclosure material that can replace ordinary cement asbestos has been developed. It is reinforced with fiberglass reinforced asbestos, which is now in the roof of some projects. Used on the wall. This is a kind of composite component that uses common cement asbestos as the bottom tire and is covered with a single layer of glass fiber cloth and polyester resin fiberglass. Good mechanical performance, low water absorption, good impact resistance, corrosion resistance, weather resistance and waterproof performance. According to the test, the transverse resistance of the tile is 335 kg, which is
