Causes and hazards of yellowing of exterior wall insulation mesh
We all know that the standard exterior wall insulation mesh is white unless it is colored and turns into yellow. Under special circumstances, the insulation mesh that is not colored is also yellow. What is going on?
Indeed, the standard color of the thermal insulation mesh cloth is white. When gluing and baking, sometimes the temperature control is very poor, so the temperature is too high, causing the insulation mesh cloth to be baked, which is the "yellow" we see. Insulating mesh cloth. Insulation mesh cloth has different specifications and materials. The temperature of the baking cloth is also different. Therefore, we need to adjust the appropriate temperature based on a series of data such as different specifications, models, thicknesses, etc. of the insulation mesh cloth to achieve the best performance of the mesh cloth. Otherwise, the temperature in the furnace will inevitably be too high, causing the insulation mesh to become hard when baked. In severe cases, it will cause the insulation mesh to bake yellow. If the temperature is too low, the insulation mesh will be too soft. There is no stereotype. This requires our workers to control and adjust based on many years of production experience.
The appearance of the thermal insulation mesh is very important. The yellowed thermal insulation mesh is not only unqualified in appearance, the most important thing is that the inner quality is compromised and the service life is reduced. The roasted yellow thermal insulation mesh is not acceptable. To avoid unsafe hidden dangers in work clothes and home decoration during sales.
