強化剤はどのような特性をテストする必要がありますか? 検出方法?
強化剤とは、材料の靭性を高めることができる添加剤を指します。, mainly used to improve the impact resistance, toughness and crack resistance of plastics, ゴム, coatings and other materials to improve the mechanical properties and service life of materials. The toughening agent is usually a polymer compound or inorganic substance, with a high molecular weight and molecular weight distribution, which can form a uniformly dispersed phase in the material, so as to effectively absorb and disperse stress, and improve the toughness and impact resistance of the material. Common toughening agents include polyurethane, acrylate copolymer, ethylene-propylene copolymer, calcium silicate, sodium aluminum silicate, 等.
