一、玻璃钢胶布质量对管材性能的影响

The influence of the quality of glass fiber reinforced plastic coating on the performance of pipes

（一）玻璃钢用树脂含量和均匀性对管材性能的影响树脂含量多，玻璃钢制品吸水性减小，电性能好。树脂含量少，电性能下降，并影响剪切强度。但其它机械性能相对提高（如抗压、抗弯等）。同一幅面树脂含量的大小也影响到管材性能。当胶量均匀时，卷制出来的管子比较平整光滑。当胶量不均匀时，卷出来的管子各部位含胶量偏差较大，胶量大的地方易起棱；胶量小的地方密度小，易产生气泡，使电性能降低。因此从质量上和工艺上，都要求有均匀的含胶量。

(1) the resin content and uniformity of glass fiber reinforced plastics affect the properties of pipes, the content of resin is more, the water absorption of FRP products is reduced, and the electrical properties are good. The resin content is low, the electrical properties decrease, and the shear strength is affected. But other mechanical properties are relatively improved (such as compression, bending, etc.). The resin content in the same width also affects the performance of the pipe. When the amount of glue is uniform, the tubes made by rolling are smoother and smoother. When the amount of glue is uneven, the volume of the tube out of each part of the gum deviation is larger, large amount of glue easy to edge; small amount of glue density is small, easy to produce bubbles, so that the electrical performance is reduced. Therefore, both the quality and the process require a uniform amount of glue.

（二）可溶性树脂含量和挥发物含量的影响

(two) the influence of soluble resin content and volatile matter content

可溶性树脂含量主要是影响粘结强度和工艺性。挥发物含量的多少影响到管材物理机械性能及电性能，尤其是对电性能影响较大。

The content of soluble resin mainly affects the bonding strength and process. The content of volatile matter affects the physical and mechanical properties and electrical properties of the pipe, especially the electrical properties.

二、玻璃钢卷管工艺条件对管材性能的影响

The influence of process conditions on the glass steel pipe pipe performance

卷制温度和速度是密切相关的，即温度低，速度要慢，温度高，速度要快。卷制温度过低，挥发物含量大，对产品的电性能不利。卷制温度过高，对产品的机械性能不利，因在高温下，挥发物会使材料形成多孔性，进而使材料的介电性能也降低。因此，要选择适当的卷制温度和速度。

Coiling temperature and speed are closely related, that is, low temperature, slow speed, high temperature and fast speed. The coiling temperature is too low and the volatile content is high, which is unfavorable to the electrical performance of the product. The coiling temperature is too high, which is harmful to the mechanical properties of the product. Because of the high temperature, the volatile will make the material form porous, and then the dielectric properties of the material will be reduced. Therefore, the proper coiling temperature and speed should be selected.

卷制压力对管材的影响主要是影响层间粘结强度、制品的密度。压力愈大，层间粘结强度越高，制品越密实。如环氧/酚醛玻璃布层压板比重为1.8克/立方厘米，而环氧!酚醛管道的比重为1.5克/立方厘米。这主要是因为层压板的成型压力远大于卷管时的成型压力。

The effect of coiling pressure on the pipe material mainly affects the bond strength between the layers and the density of the products. The greater the pressure, the higher the bond strength between the layers, the more compact the product. The epoxy / phenolic glass cloth laminate has a specific gravity of 1.8 grams / cubic centimeter, while the epoxy phenolic pipe has a specific gravity of 1.5 grams / cubic centimeter. This is mainly because the molding pressure forming pressure laminate is far greater than the volume of the.
