PC工艺
生产聚碳酸酯纺织筒管时，选择光气法生产的PC作为原材料，其中80%为新材料，20%为回收材料。生产过程如下：
配料→ 烘干→ 注射→ 完成→ 抛光→ 热处理→ 产品
烘箱的干燥温度为115-120℃，16-20小时，托盘上的材料厚度小于30mm，因此树脂水分含量小于0.03%
筒体三个区域的温度为200-220、250-280、260-290°C，喷嘴温度略低于筒体温度，比筒体温度低5-10°C。注射压力为60-100MPa，成型周期为25秒，热处理温度为115-120°C，持续1小时。热处理采用倒置悬挂式
筒子的使用寿命是木制筒子的三倍，尺寸稳定，耐候性好，不起毛，光洁度好。可提供多种颜色的筒管，方便团队进行经济计算
对于废弃的可回收PC材料，也可以进行增韧处理以替代新材料。可与回收PC材料中的少量尼龙树脂或高抗冲聚苯乙烯树脂混合，可将产品的冲击强度提高一倍以上，提高弯曲强度。提高了树脂的加工性能和表面光洁度。进步了很多
此外，由于尼龙在熔融过程中的粘度极低，它可以对共混体系中的颜料具有极好的润湿和覆盖效果，破坏颜料的聚集性，增加颜料的分散性。因此，可以减少颜料的用量。20%.

Product Details
PC process
For the production of polycarbonate textile bobbins, PC produced by the phosgene method is selected as the raw material, of which 80% is new material and 20% is recycled material. The production process is as follows:
Ingredients → drying → injection → finishing → polishing → heat treatment → products.
PC process
The drying temperature of the oven is 115-120℃, 16-20 hours, the thickness of the material on the tray is less than 30mm, so that the resin moisture content is less than 0.03%.
The temperature of the three zones of the barrel is 200-220, 250-280, 260-290°C, and the nozzle temperature is slightly lower than that of the barrel, 5-10°C lower. The injection pressure is 60-100MPa, the molding cycle is 25 seconds, and the heat treatment temperature is 115-120°C for 1 hour. The inverted suspension type is used for heat treatment.
The bobbin has a service life three times longer than that of a wooden bobbin, is dimensionally stable, has good weather resistance, is lint-free, and has a good finish. It can provide bobbins of various colors, which is convenient for the economic calculation of the team.
For waste recycled PC materials, toughening treatment can also be carried out to replace new materials. It can be blended with a small amount of nylon resin or high-impact polystyrene resin in the recycled PC material, which can increase the impact strength of the product by more than one time, and improve the bending strength. The processing performance of the resin and the surface smoothness are improved. Improved a lot.
In addition, due to the extremely low viscosity of nylon during melting, it can have an excellent wetting and covering effect on the pigments in the blending system, destroying the aggregation of the pigments and increasing the dispersibility of the pigments. Therefore, the amount of pigments can be reduced. 20%.
