Defects in fiberglass grating panels can to some extent lead to a decrease in product quality, so great care should be taken during the repair process. The original grid should maintain corrosion resistance, mechanical properties, and flame retardancy to avoid defects caused by uneven skin color, excessive, inappropriate, and excessive catalytic curing shortening operations.
The appearance quality of fiberglass grating panels has disadvantages such as uneven color, white color, impurities, bubbles (appearance, center, bottom) and thickness errors, lack of curing degree and resin layer richness, cracking (formed by curing resin richness and reducing defects), top pins, warping, compensation defects, etc. It is necessary to establish a strict quality inspection standard system and specifications. The appearance of the grille also greatly affects the appearance quality of the product, forming a consistent crescent or anti slip sand appearance. It is also worth paying attention to the manufacturer of a lubricated fiberglass grille panel.
There are too many industrial samples and problems in China, and product quality has been neglected. The supplied goods are significantly different from the samples. Insufficient understanding of quality control in the production process can lead to many human operation defects, such as uneven color, impurities, bubbles, thickness errors, resin layers, defects, and so on. The defects of the curing system include the formation of white, foaming, delamination, insufficient curing degree, cracking, etc. Another drawback of deformation is mainly caused by the unreasonable fiber layer structure and curing system, which many manufacturers have not handled well. In addition, the color aging of fiberglass grating products is severe, mainly due to poor quality of pigment paste and the lack of quantitative UV absorbers.
