Selection of Resin Types for Fiberglass Grating
Release time:
2020/03/23
The main raw materials for producing fiberglass grating include resin, fiberglass, and filler powder, each of which consists of various types. Below, we will focus on introducing three commonly used types of resin for fiberglass grating: ortho-type, iso-type, and vinyl-type. The price is proportional to the corrosion resistance, so it is important to select the most economical type of resin based on the corrosive medium in the usage environment by consulting performance descriptions and corrosion resistance tables. A. Ortho-type: It has ordinary corrosion resistance, can withstand atmospheric aging, seawater corrosion, etc., and has a long-term usage temperature of -50 to 60°C. B. Iso-type (Municipal use): It has excellent corrosion resistance and can...
The main raw materials for producing fiberglass grating include resin, fiberglass, and filler powder. Each raw material includes different types. Below, we will focus on introducing three commonly used types of resin for fiberglass grating: orthophthalic, isophthalic, and vinyl.
Its price is proportional to its corrosion resistance, so it is necessary to select the most economical type of resin based on the corrosive medium in the usage environment by consulting performance descriptions and corrosion resistance tables.
A. Orthophthalic: Has ordinary corrosion resistance, can withstand atmospheric aging, seawater corrosion, etc., with a long-term usage temperature of -50~60℃.
B. Isophthalic (Municipal Use): Has excellent corrosion resistance, can withstand environments with medium concentrations of inorganic acids, alkalis, and various salts, with a long-term usage temperature of -50~90℃.
C. Vinyl (Chemical Use): Has outstanding corrosion resistance, can withstand harsh corrosive environments such as acids, alkalis, salts, solvents, or alternating acid-alkali, with a long-term usage temperature of -50~110℃.
From the above content, we can see that the performance of grating products made from different types of resin also varies. So, which type of resin is more effective?
The answer to this question is actually very simple. We should decide which type of resin material to use based on the specific environment in which the grating board will be used. If it is only used as a tree guard or a cargo rack with low corrosion resistance requirements, then choosing orthophthalic resin is sufficient. Conversely, if it is used in highly corrosive environments such as chemical plants, sewage treatment, or offshore platforms, then a more corrosion-resistant vinyl resin should be selected.
Of course, the prices of grating boards made from different types of resin also vary. Orthophthalic is more economical, while vinyl has excellent corrosion resistance but is relatively more expensive. Therefore, we need to choose a more economical and suitable type of raw material based on the specific environmental requirements.
In addition to resin materials, there are also different types of fiberglass roving and fillers available for making grating boards. Fiberglass, as the main load-bearing carrier of the grating board, is the primary material affecting the load-bearing performance of the grating. Different types of fillers provide varying flame-retardant effects for the grating board.
Finally, after determining the production materials for the fiberglass molded grating, it is also necessary to choose the specifications and dimensions of the grating board. The thickness of the grating board is a major factor affecting its load-bearing strength, and the appropriate thickness should be selected based on the requirements of the usage environment. As for the specific dimensions of the product, we can customize and produce products of various specifications and sizes according to customer requirements.
In summary, to ask which type of resin is better for fiberglass grating, it is necessary to consider the specific type of environment in which it will be used. Guangxi Fiberglass Products Co., Ltd. is a professional manufacturer specializing in the production and research of fiberglass grating. We welcome your inquiries.
