Common abnormal problems of FRP Bridge include the following 5 points: 1. Sticky surface; 2. Many bubbles; 3. Glue flow; 4. Stratification; 5. Poor drying and solidity. The following is a detailed answer from Jinan Bridge manufacturer.
1、表層發粘,環境濕度較大,水分過于聚集;再有就是由空氣中氧的阻聚導致的。解決方案是:在環氧樹脂中添加一部分石臘,在玻璃鋼橋架表層噴一層環氧樹脂膠甲苯溶液,或者在表層涂一層冷干漆;
1. The surface is sticky, the environmental humidity is high, and the moisture is too concentrated; Furthermore, it is caused by the polymerization inhibition of oxygen in the air. The solution is: add a part of stone wax to the epoxy resin, spray a layer of epoxy resin glue toluene solution on the surface of the FRP Bridge, or apply a layer of cold dry paint on the surface;
2、氣泡多,造成原因是樹脂使用量過多,需要改進攪拌方式,降低黏劑中的氣泡,樹脂黏度很大,可提高環境溫度,采用樹脂非常容易浸透的無捻玻璃布等。
2. There are many bubbles. The reason is that too much resin is used. It is necessary to improve the mixing method to reduce the bubbles in the adhesive. The viscosity of the resin is very high, and the ambient temperature can be increased. The twistless glass cloth, which is very easy for the resin to soak, is used.
3、流膠,俗成環氧樹脂瘤,環氧樹脂黏度小,可添加適度二氧化硅粉,也可能是用料不均勻,需要充足攪拌。
3. Glue flow, commonly known as epoxy resin tumor, epoxy resin viscosity is small, appropriate silica powder can be added, or the materials may be uneven, and sufficient mixing is required.

4、分層,由于玻璃布未脫臘或返潮造成,環氧樹脂使用量不夠或玻璃布未卡緊,熱固時間太早、過急或過高發。
4. Delamination is caused by the glass cloth not dewaxing or returning to moisture, insufficient use of epoxy resin or the glass cloth not tightly clamped, and the thermosetting time is too early, too fast or too high.
5、干固欠佳,由于溫度過低,環境濕度過大,環氧固化劑或硫化促進劑使用量不夠或不成功導致的。
5. Poor dry curing is caused by too low temperature, too high environmental humidity, insufficient or unsuccessful use of epoxy curing agent or curing accelerator.
此外玻璃鋼橋架設備前,應依據施工圖斷定始端到終端方位,沿圖紙標定走向,找好水平、筆直、彎通,用粉線袋或畫線沿橋架走向在墻壁、頂棚、地上、梁、板、柱等處彈線或畫線,并均勻檔距畫出支、吊、托架方位。
In addition, before the installation of FRP Bridge equipment, the orientation from the beginning to the end shall be determined according to the construction drawing, and the alignment shall be calibrated along the drawing to find the horizontal, straight and curved connection. The lines shall be snapped or drawn on the wall, ceiling, ground, beam, plate, column, etc. along the bridge alignment with powder line bags or lines, and the orientation of supports, hangers and brackets shall be drawn with uniform spacing.
