At present, there are more and more manufacturers making color steel purification plates in the market, and various quality problems follow. Next, Jinan Color Steel Sandwich Panel Factory will talk about the reasons for the softening and color difference of color steel purification plate!
Reasons for softening of color steel purification plate:
1. The gel time is too long.
2. The resin of the color block of the purification plate does not contain wax.
3. The temperature is too high or too low during casting.
4. The ambient temperature of the clean room is too high.
Reasons for color difference of color steel purification plate:
1. The resin mixture is not stirred sufficiently.
2. Paint measurement error.
3. Do not use premixed dispersion mixing.
4. The drying room is partially overheated and the plates are unevenly heated.
In addition, during the prefabrication of color steel purification plates in the factory, the gap and installation allowance between door openings, window openings and joints shall be fully considered according to experience. During the whole process of transportation and installation, prevent scratches, heavy pressure and surface collision, and prevent pits and scratches from being uncorrectable.
Get familiar with the drawings, carefully review the unknown contents such as the plane layout, node requirements, the relationship between the color steel purification plate and the building, the color of the color steel purification plate itself, filler and basic size requirements, the size and layout of doors and windows, and the type of auxiliary materials in the color steel purification plate partition.
The sealing silica gel shall be installed on the color plate in good sanitary condition. After cleaning and dedusting, it shall be unified. Otherwise, the silicone joint is easy to be polluted and blackened. Within 24 hours after the silica gel is grouted, there should not be a lot of dust operations and the ground should not be washed with water, which may affect the curing and firmness of the sealing silica gel.
In fact, to ensure that the color of the board is not affected, we need to control the entire production process, especially when brushing the outer layer of paint, we should not only pay attention to the uniform application, but also the paint should meet the use requirements.
