The Following Are Common Problems in The Manufacture Of Bubble Film

First, forming problems
1. The forming of bubble film is not smooth, resulting in wavy or broken phenomenon.
Possible causes: insufficient heating temperature, insufficient heating time, cooling speed too fast or too slow, unreasonable composite structure, insufficient pressure, etc.
Solution: Adjust the heating temperature and heating time, speed up or slow down the cooling speed, check whether the composite structure is reasonable, and increase the pressure.
2. The surface of the bubble film is rough or bubbles appear.
Possible causes: insufficient molding pressure, uneven material, heating temperature is too high or too low, bubble film area is too large.
Solution: Increase the molding pressure, check whether the material is flat, adjust the heating temperature, and control the size of the bubble film area.
Second, the thickness problem
1. Uneven thickness of bubble film.
Possible causes: the extruder speed is unstable, die head or extruder wear, uneven temperature, inconsistent moisture content of bubble film material, etc.
Solution: Ensure that the extruder speed is stable, replace the die head or extruder parts, coil or surface heating control temperature uniform, to ensure that the material moisture content is consistent.
2. The thickness of the bubble film exceeds the standard.
Possible causes: extruder speed is too fast, die Angle is too small, die head aperture is too large.
Solution: Reduce the extruder speed, adjust the die Angle or replace the suitable die head, reduce the die head aperture.
Three, core tube problem
1. The bubble film is loosely rolled or deformed.
Possible causes: the inner diameter of the core tube is inconsistent, the core tube is loose, and the tension is uneven.
Solution: Use a better quality core tube and adjust the winding tension.
2. Core tube is broken or deformed.
Possible causes: insufficient strength of the core tube, mismatch of the outer diameter of the core tube, poor quality of the core tube.
Solution: Replace the core tube with a better quality and ensure that the outer diameter of the core tube matches.
Fourth, the take-up problem
1. The bubble film leaks or rolls into a loose "lying silkworm chrysalis".
Possible causes: uneven tightening force, winding speed is too fast or too slow.
Solution: Adjust the tension and match the appropriate winding speed to ensure the stability of the winding.
2. The bubble film is not neatly rolled or has rough edges.
Possible causes: The edge of the bubble film is not neat, the core tube is loose, and the winding pressure is not equal.
Solution: Check whether the edge of the bubble film is neat, adjust the winding pressure, and ensure the stability of the core tube.
To sum up, the common problems in the process of bubble film manufacturing are mainly concentrated in the forming, thickness, core tube and coiling, etc. To solve these problems, the parameters and conditions of each link need to be adjusted to ensure the stability of the production process and quality stability, so as to improve product quality and production efficiency.
