강화제는 어떤 특성을 테스트해야 합니까?? 감지 방법?
강인화제는 재료의 인성을 증가시킬 수 있는 첨가제를 말합니다., mainly used to improve the impact resistance, toughness and crack resistance of plastics, 고무, 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, 등.
