Common Causes of Defects in quality SILICONE RUBBER COATED FIBERGLASS SLEEVING

2023-03-28

The quality SILICONE RUBBER COATED FIBERGLASS SLEEVING is widely used for their excellent protection properties. If quality problems occur during the production process, it will affect the safety protection performance. So what is the cause of the problem with quality SILICONE RUBBER COATED FIBERGLASS SLEEVING?
1. There are air bubbles in the quality SILICONE RUBBER COATED FIBERGLASS SLEEVING. Reasons: (1) Mechanical failure or excessive mechanical speed; (2) Abnormal raw rubber quality; (3) Too high paint concentration and high feeding temperature;
2. The inner diameter of quality SILICONE RUBBER COATED FIBERGLASS SLEEVING is small (large). Reasons: (1) The weaving method of the tube blank is abnormal; (2) Improper use of tooling, wear, dirty tooling, and debris in the tube; (3) The transmission of the machine has failed, resulting in a deviation in the inner diameter.
3. The voltage of the glass fiber sheath is lower than the stable value. Reasons: (1) The paint concentration is too low, which affects the withstand voltage performance; (2) Bubbles are generated; (3) The quality of the original rubber is not up to standard. The tube blank is not well woven, too sparse and loose.
4. The color of the quality SILICONE RUBBER COATED FIBERGLASS SLEEVING is uneven. Reasons: (1) The dewaxing temperature is unstable; (2) The dewaxing temperature is not set properly, and the outside air enters the dewaxing furnace; (3) The weaving of the tube blank is abnormal; (4) There are particles on the glass fiber tube.
5. The wall thickness of the quality SILICONE RUBBER COATED FIBERGLASS SLEEVING does not meet the requirements. Reasons: (1) Irregular tube blank weaving; (2) Inappropriate paint concentration is not required when the inner hose is extruded, or the extrusion wall thickness is unstable; (3) The speed setting of the machine is incorrect or unstable .
