Shanghai Daoqin Plastics Co., Ltd.

         recycled plastics commonly used additives has:

        (l) filler: more filler reinforcement function, meanwhile is plastics modified, made composite/compounding material important formed separation,例如石墨, 二硫化 aluminum, fiber and glass fiber and other; also filling agent or filler. filler in plastics formed material in 约占40%一70%, commonly used filler has powder, slip powder, silicon 藻土, 石灰石 powder, aluminum powder, 炭黑, 云母, 二硫化 aluminum, 石棉, glass fiber and other. its in fiber filler can improve/increase plastics structure strong/high degree;石棉 filler can improvement plastics heat resistant property;云母 filler can reinforcement plastics electrical insulation property;石墨, 二硫化 aluminum filler can improvement plastics abrasion scratch and wear resistance can and other. in addition, due to filler generally ratio combined formed resin 便宜,故 filler add can reduce plastics cost.

        (2) solid 化: also hard agent or agent. its function in through crosslinked make resin tool has type structure, formed is relatively hard and stability products, different product types resin using/adopting different product types solid agent. 例如, in aldehyde resin in add 入六亚甲基四 amine, in ring oxygen resin in add 入乙二 amine, 顺丁烯二 acid and other.

        (3) increase agent: is improve/increase plastics in processing can property and products flexibility property, elastic property and other,

         in plastics products production processing need add a small amount of increase agent. increase agent usually is tool has easy molecular weight relatively low solid or liquid has machine combined material. main/primary is type and ketone type, commonly used has 邻苯二甲 acid 二辛脂, acid 二辛脂, acid 二甲苯脂, adipic acid 脂, 二苯甲 ketone and other. 例如, polyvinyl chloride (PVC) resin in add 入邻苯二甲 acid 二丁脂, can make plastics soft/flexible has elastic property,但 research table/sheet 明, it can for 实验动 material device 官, liquid, 肾脏, 肺脏, and other multiple device formed loss 伤, especially is and 发育期儿童 for its function non 常敏感.

        (4) stabilizer: 人造草坪 in molding processing and use process in, due to hot, light oxygen function, 早 发生 degradation, oxidation 断链, crosslinked and other phenomenon, make material property can bad. is anti hot, light and other function make plastics fiber aging add a small amount of can stability function material 质,例如,添 add type and amine type and other has machine material can resistant oxidation,炭墨则 can used as outer absorption agent; heat stabilized agent is remove increase agent outer plastics products in use most more additives. 总 说, ring oxidation types or material large 豆油(ESBO) and other by a large amount of used as plastics food packaging materials heat stabilized agent, lubricant and increase agent and other. poly chlorine dilute, poly chlorine ethylene and polystyrene (PS) and other material usually has 0. 1%~27%不 and other ring oxidation material 油. due to material in ethylene oxidation material property strong/high, therefore pure degree will effect/influence its property degree. usually, its molecular weight large (即 solvent understanding degree small), property low.

        (5) flame retardant: function is retardant 止燃烧 or formed self-extinguishing, comparison formed flame retardant has oxidation and other machine material or acid type and 含澳化 combined material and other has machine material.

        (6) color agent: is make plastics products tool has color color and gloss, can add color agent. color agent its in color in solvent understanding property separation is material and material. material is has machine combined material, can solvent by color resin in;颜 material generally is machine combined material,不 solvent by color 介质, its color property is through high dispersion property pellets dispersion by 染介质, its rate and 基体差别 large, absorption separation light,而 also 反射另一部 separation light 线, to color 视觉. material not only for plastics tool has color property, meanwhile has filler and stabilizer function. in addition, according to construction plastics use and molding processing in need, has also add lubricant, anti-static agent, foaming agent, flame retardant and anti agent and other.
