产品详细信息

聚酰胺尼龙PA66

主要方法是在聚合过程或加工过程中添加适量的添加剂，使树脂具有各种不同的特性，使其适合各种不同的使用场合。常用的添加剂有：① 稳定器。包括热稳定剂和光稳定剂，分别提高聚酰胺的抗氧化性和耐光性，制备耐老化尼龙。如果添加2%（质量）的精细分散炭黑，聚酰胺可以在户外长期使用。②常用的玻璃纤维增强材料。增强尼龙用于增加刚性，减少蠕变，降低产品的成型收缩率，提高尺寸稳定性。采用金属纤维增强，不仅具有高模量，而且具有导电性。矿物的使用也有很好的增强效果，使加工成型容易，降低了成本。二硫化钼和聚四氟乙烯也是聚酰胺的增强材料，可以提高耐磨性。③ 成核添加剂。用于制备微晶尼龙，可加快脱模时间，缩短成型周期20%-30%。此外，根据不同的用途，还可以添加增塑剂和润滑剂

Product Details

Polyamide nylon PA66

The main method is to add an appropriate amount of additives in the polymerization process or processing process to give the resin a variety of different characteristics, making it suitable for a variety of different use occasions. Commonly used additives are: ① Stabilizer. Including heat stabilizer and light stabilizer, they can respectively improve the oxidation resistance and light resistance of polyamide to prepare anti-aging nylon. If 2% (mass) of finely dispersed carbon black is added, polyamide can be used outdoors for a long time. ②Commonly used glass fiber reinforced materials. Reinforced nylon is made to increase rigidity, reduce creep, and reduce the molding shrinkage rate of the product and improve the dimensional stability. Reinforced with metal fiber, not only has high modulus, but also has conductivity. The use of minerals also has a good reinforcement effect, and makes the processing and molding easy and the cost is reduced. Molybdenum disulfide and polytetrafluoroethylene are also reinforcing materials of polyamide and can improve wear resistance. ③ Nucleating additives. Used to prepare microcrystalline nylon, which can speed up demolding time and shorten the molding cycle by 20% to 30%. In addition, according to different uses, plasticizers and lubricants can also be added.
