Fiberglass grating is mainly composed of resin, fiberglass fibers, and filler calcium powder in a certain proportion. High quality fiberglass grating is particularly crucial in the selection of raw materials, which directly affects the performance and quality of the product.
Firstly, resin is an important component of fiberglass grating. The high-quality fiberglass grating is made of unsaturated ortho benzene resin 196, which is colorless and transparent. It has the characteristics of low viscosity, low heat release, low shrinkage, high-speed curing, high-speed compatibility, and high glossiness. The fiberglass grating produced using this resin has a flat and smooth surface, good glossiness, high strength, and a certain degree of toughness. The use of inferior resin in the production of grilles can lead to problems such as turbidity, high viscosity, high heat release, high shrinkage, slow curing, and poor compatibility, resulting in products with multiple pores, easy cracking, poor strength, and poor toughness.
Secondly, fiberglass fiber is a key material for enhancing the toughness of grilles. High quality fiberglass fibers, such as alkali free fiberglass fibers, have higher strength than steel wires, certain toughness, good chemical stability, strong weather resistance, almost no water absorption, and do not burn when exposed to fire. In addition, its high strength also makes it suitable for use as tire cord. In fiberglass grilles, fiberglass fibers are usually laid in 8-9 layers to ensure the strength of the product. However, some manufacturers may use high alkali fibers to impersonate alkali free fibers, which have lower strength and poor water and alkali resistance.
Therefore, when choosing fiberglass grilles, consumers should pay attention to the selection of raw materials for the product. High quality raw materials are the foundation for producing high-quality fiberglass grilles. At the same time, consumers can also preliminarily judge the quality of the product by observing its appearance, glossiness, toughness, and other aspects. If conditions permit, it is recommended that consumers choose legitimate and reputable manufacturers to purchase to ensure the quality and performance of the products.
