With the continuous development and innovation of silica gel industry, silica gel products are widely used in various industries, and there are more and more silica gel products on the market, but there are also some inferior or fake silica gel products on the market at present, so how do we judge the quality of silica gel products when buying silica gel products?
1. Wear resistance:
Wear resistance is the production and molding of silica gel products, and the surface of silica gel products can suffer loss. The general surface of good silica gel products is rarely rubbed off the surface of the product due to external factors, and does not affect the appearance, text and color of the surface. The surface characters of inferior silica gel products are easy to drop.
2. The elastic:
Silica gel products have good elasticity, because high elasticity mainly comes from the movement of silica gel molecular chain segment, so when buying silica gel products, look at the elasticity of silica gel products to judge the quality.
3. Fatigue resistance:
Silica gel products by alternating stress (or strain), the structure and performance of the material changes phenomenon is called fatigue. As the fatigue process progresses, the phenomenon that leads to the destruction of silica gel products is called fatigue destruction. So fatigue resistance is also a way to identify the quality of silica gel products.
4. Tearing strength and tensile strength:
Silica gel products with high tear strength have outstanding damage resistance, long life, and are not easy to be disturbed by the external environment. Silica gel products with poor tear strength are generally prone to cracks in the tearing process, so as to rapidly expand cracking and lead to damage when stressed.
5. Hardness and fixed elongation stress:
Hardness and fixed extension stress reflect the rubber material rigidity (stiffness) important indicators, both are the force required by silica gel products to produce a certain deformation, is also a way to identify the quality of silica gel products.
