影响自封口袋缩短率的几个要素

发布日期:2022-12-29 作者:bjmj111.com 点击:

常见的自封口袋类型有许多,那大家知道影响自封口袋缩短率的要素有哪些呢?下面济南自封口袋厂家就来为您讲解相关信息。
There are many common types of self sealing pockets. What are the factors that affect the shortening rate of self sealing pockets? Now Jinan Self sealing Pocket Factory will explain relevant information for you.
1、自身结构
1. Self structure
同一自封口袋中,壁厚较小的部位的缩短率要小于壁厚较大的部位,远离嵌件部位的缩短率要大于靠近嵌件部位的缩短率,垂直于活动方向与活动方向的缩短率也是有不同的,一般情况下活动方向缩短率大于垂直于活动方向的缩短率,自封口袋受到阻挠方向的缩短率要比无阻挠方向的缩短率要小。
In the same self sealing bag, the shortening rate of the part with smaller wall thickness is smaller than that of the part with larger wall thickness, the shortening rate of the part far from the insert is greater than that of the part close to the insert, and the shortening rate perpendicular to the moving direction is also different from that of the moving direction. Generally, the shortening rate of the moving direction is greater than that perpendicular to the moving direction, and the shortening rate of the self sealing bag in the obstructed direction is smaller than that in the non obstructed direction.
2、原材料
2. Raw materials
用不同原材料出产的自封口袋的缩短率是不同的,但是运用相同质料出产的不同批次的自封口袋缩短率也不相同,这主要是受到了加工出产过程的影响,结晶型的塑料的缩短率要大于无定形的塑料,活动性差的塑料成型缩短率大,活动性好的塑料成型缩短率小,假设在塑料中参加填充料会导致成型的塑料缩短率明显下降,不添加填充物的塑料出产成型后的缩短率更好。
The shortening rate of the self sealed bags produced with different raw materials is different, but the shortening rate of the self sealed bags produced with the same materials in different batches is also different, which is mainly affected by the processing and production process. The shortening rate of crystalline plastic is greater than that of amorphous plastic. The molding shortening rate of plastic with poor mobility is large, and the molding shortening rate of plastic with good mobility is small, It is assumed that the filling material in the plastic will lead to a significant decrease in the plastic shortening rate, and the plastic without filling material will have a better shortening rate after production and molding.

3、压力和温度
3. Pressure and temperature
压力过高会使得自封口袋的密封添加,导致缩短率减小,假设进步出产自封口袋的原材料的温度,会使得自封口袋的体积胀大,通过压力入型的物料变少,使得缩短率增大,但是原材料的温度升高会使得粘度变小,粘度变小会使得型腔内的压力增多,使得自封口袋的缩短率减小,所以终究影响自封口袋的缩短率的要素取决于压力和原材料温度两者的概括影响。
If the pressure is too high, the sealing of the self sealing bag will be added, leading to a reduction in the shortening rate. Suppose that the increase in the temperature of the raw materials used to produce the self sealing bag will cause the volume of the self sealing bag to swell, and the materials used to press into the mold will become less, leading to an increase in the shortening rate. However, if the temperature of the raw materials rises, the viscosity will become smaller, leading to an increase in the pressure in the mold cavity, leading to a decrease in the shortening rate of the self sealing bag, Therefore, the factors that affect the shortening rate of self sealing bags ultimately depend on the general effects of pressure and raw material temperature.
