What problems do glass fibre tubes have and analysis of the causes?

Glass fibre sleeving is a special glass fibre sleeving made from glass fibre woven into a tube and then processed by a high temperature shaping process

  1. Glass fibre tubes with vapour bubbles.

Causes.

  1. too high a concentration of lacquer, too high a temperature of lacquering.
  2. Machine speed is too fast.
  3. Machine failure.
  4.  abnormal quality of the original glue.
  5. Inappropriate workwear.
  6. Serious paint seepage and bubbles on the inner wall of the tube.

Second, the inner diameter of the glass fiber tube is small (large).

Causes.

1, improper use of workwear, wear and tear, dirty workwear, debris in the hole.

2, abnormal weaving of the blank tube.

3, flat tube.

4, machine transmission failure.

Three, the voltage is not enough (stable).

Causes.

1、Lacquer concentration is too low.

2, out of the bubble.

3、The original glue quality problem.

4, poor weaving of the blank tube, too thin and loose.

5、Employee operation error.

  1. Uneven colour of glass fibre casing.

Causes.

1、Improper setting of dewaxing temperature.

2、Dewaxing temperature is not stable.

3、Cold outside air entering the dewaxing furnace.

4, billet tube weaving abnormalities.

  1. Glass fiber tube with particles.

Causes.

1、Overpainting not filtered cleanly.

2、Lacquer barrel has not been cleaned for a long time.

3, the original rubber quality has abnormal.

4、The guide wheel is not clean, there is hard glue stained to the blank tube.

  1. Glass fibre tube stains.

Causes.

1, caused by the previous process.

2、Water, oil or other pollutants stained at the blank tube through the blank.

3, string colour.

4, mopping stained with dust or other debris.

5, paint is not clean, there are debris or mixed with other colours.

Seven, wall thickness does not meet the requirements.

Cause.

1、Blank tube weaving does not meet the requirements.

2, the inner rubber tube extrusion does not meet the requirements or extrusion wall thickness is not stable.

3、Inappropriate paint concentration.

4、Inappropriate or unstable machine speed setting.
