Glass fiber short cut felt uniformity control

In the process of glass fiber short cut felt, the control of evenness is involved in three aspects: valve, weight, friction and static electricity.

Here are three ways to break down!

 

Control of f gas

 

According to the principle of sedimentation, the homogeneity of short cut felt is very important to f gas.

Therefore, how to control the f gas is the top priority of the felting.

We adopt the control of frequency control for each fan, and control the weight uniformity of the short-cut felt by adjusting the wind flow rate at the bottom of the settling chamber.

If the short cut felt in a certain part is always light, and the short felt of the adjacent area is heavy, then the damper is adopted to reduce the air door of the heavy part.

If the short cut felt in a certain area is always light, and there is no one part of the short cut felt, then the filling method is used to increase the weight.

It needs to be pointed out that because the distribution of the short cut yarn in the settling chamber is very disorganized and disorderly, the position of the tile is random, and the sealing of the settling chamber is particularly important.

The two sides of the general settling chamber and the inlet seal are made of soft plastic sheet. The outlet is sealed with a light aluminum tube, one of which has the function of sealing, and the other hand has the effect of pressing the felt surface.

Because the width of the short cut felt is adjusted by the side plates on both sides of the settling chamber, the mesh belt has a serious wear and tear on both sides of the plastic sheet, and the replacement cycle is short.

Moreover, settling chamber f gas in the form of circulation wind, bound to lead to part of the short cut fiber through forming net belt into the duct, into the duct of the short cut fiber with convulsions in chopped room, chopped chamber of the working environment.

In view of this, a filter is installed near the fan to reduce the fibre entering the duct.

However, the filter screen will slowly absorb a layer of glass fiber, blocking the passage of the wind, so that the f gas is reduced.

Domestic some by forming the wind outside, it will not be affected by the factors, but the way of short cutting room air flow and temperature and humidity is big, does not favor the chopped strand of subsidence and subsidence control.

 

F weight control

 

After chopped strand of evenly spread to mesh belt is the route by its sets and the average speed of decision, because under the direction of gravity, its movement trajectory is very complicated, for finalize the design equipment and stable wind circulation, the settling chamber height H and f gas as often.

According to the principle of settlement, to get the uniform product, chopped yarn quality is also an important parameter, when heavy > f f gas, its along the direction of f heavy movement speed is greater than its along the direction f gas velocity, the mat surface "tile rotavirus would happen.

Therefore, it is necessary to control the moisture of glass fiber raw silk in production. The water is high, and the raw silk is not easy to be dispersed after cutting, and filament and fiber bundles are easily found in the short cut felt.

 

F and f static control.

 

When chopped strand is the f and f static increases, the strand will together to fall in forming net take or adsorption in the settling chamber walls, so how to control these two factors: first, in the original silk production, its infiltration agent adding a small amount of antistatic agent;

Second, control the yarn rack room and the drying humidity of the molding room.
