1)耐腐蚀性好。

1) good corrosion resistance.

玻璃钢井室能抵抗酸、碱、盐、海水、未经处理的污水、腐蚀性土壤或地下水及众多化学流体的侵蚀。比传统材质井室的使用寿命长，其设计使用寿命可达30年以上。

FRP wells can resist the erosion of acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater and many chemical fluids. The service life of the well chamber is longer than that of the traditional material well, and its design service life can be over 30 years.

对玻璃钢井室而言，由于其具有无需防腐、使用寿命大大延长、安装简便等优点，因此，受到了市政排水行业的广泛欢迎。

For glass fiber reinforced plastic well chamber, because it has the advantages of no need of anticorrosion, long service life and easy installation, it has been widely welcomed by the municipal drainage industry.

2)防污抗蛀。

2) antifouling and moth resistance.

玻璃钢井室的不饱和聚酯树脂表面洁净光滑，不会被污水中的甲贝、菌类等微生物玷污蛀附，以致增大糙率，增加维护费用。

Unsaturated polyester resin in glass fiber reinforced plastic well chamber is clean and smooth, and it will not be contaminated by Mallas or fungi and other microorganisms, so as to increase roughness and increase maintenance cost.

3)耐热性、抗冻性好。

3) good heat resistance, good frost resistance.

在-30℃状态下，仍具有良好的韧性和极高的强度，可在-50℃－80℃的范围内长期使用，采用特殊配方的树脂还可在110℃以上的温度工作。

At -30 DEG C, still has good toughness and high strength, can be used for a long time in the range of -50 DEG C 80 DEG C, the temperature of resin with special formula can be more than 110 DEG C.

4)自重轻、强度高，运输安装方便：

4) light weight, high strength, convenient transportation and installation.

采用纤维缠绕生产的玻璃钢井室，其比重在1.8－2.0，但强度可达50-120Mpa，这样它就可以按用户的不同要求，设计成满足各类承受内、外压力、轴向受力要求的结构。它与配管之间的承插连接方式，安装快捷简便，同时降低了吊装费用，提高了安装速度。

The glass fiber reinforced plastic chamber produced by filament winding has a specific gravity of 1.8 to 2, but its strength can reach 50-120Mpa. So it can be designed according to the different requirements of users to meet all kinds of structures that bear internal and external pressure and axial force requirements. It is fast and easy to install, which reduces the cost of hoisting and improves the installation speed.
