准确的计量和投料是原料批次稳定的关键

1。一对测量设备的精度要求。补充料位的选择是适当的，以避免补充时进料波动的影响

3。液体进料需要在短时间内实现连续稳定的产量

桶形结构，长径比大于56更好

反应挤出需要较长的停留时间

圆筒的长径比选择在56到60之间

真空脱挥有助于减少残渣

1。为了减少残留物，真空应增加脱气量。真空度控制不尽可能高，应确保真空度，同时避免真空口回流

3。控制残留物的最有效方法是控制添加的过氧化氢量

过滤器

1。为避免浪费性停机，应选择柱塞式双工位不停机过滤器。选择柱塞式过滤器的另一个原因是，柱塞式过滤器具有较高的加工精度，且不易泄漏。它很好地适应了熔融吹塑材料的低粘度和良好流动性的特点

3。过滤器的加热效率不应低于挤出机的加热效率，从而节省保温时间

挤出机出料部分

1。孔间距不应太小，以避免材料在出口处粘在一起。孔径一般为Φ2.8mm-Φ3.2mm。排放口与冷却水箱相连，应确保料带从模具开口流出时立即进入冷却水

Accurate metering and feeding is the key to the stability of raw material batches

1.Precision requirements for a pair of measuring equipment

2.The selection of replenishing material level is appropriate to avoid the impact of feeding fluctuation during replenishing

3.A liquid feed needs to achieve continuous and stable output in a short time

Barrel configuration, length-diameter ratio above 56 is better

A reactive extrusion requires long residence time.

The length-diameter ratio of the cylinder is selected from 56 to 60

Vacuum devolatilization helps reduce residue

1.In order to reduce the residue, the vacuum should increase the amount of degassing

2.The control of a vacuum degree is not as high as possible, and the vacuum degree should be ensured while avoiding the return of the vacuum port.

3.The most effective way to control residue is to control the amount of peroxide added

Filter

1.To avoid wasteful shutdown, plunger-type dual-station non-stop filter should be selected

2.Another reason for choosing the plunger filter is that the plunger type has high processing accuracy and is not easy to leak. It is well adapted to the characteristics of low viscosity and good fluidity of melt-blown materials.

3.The heating efficiency of a filter should not be lower than the heating efficiency of the extruder, saving heat preservation time

Extruder discharge part

1.The hole spacing should not be too small to avoid the material sticking together at the exit

2.The aperture is generally Φ2.8mm-Φ3.2mm

3.The discharge is connected with the cooling water tank, and it should be ensured that the material strip

enters the water for cooling immediately when it flows out from the die opening

Application: Meltblown
