How to quickly dry old paint in low temperature environment during decoration?

During the winter construction, painters in many furniture factories add desiccants and curing agents to paint at will to increase the number of products, which will dry the paint, but it will directly affect the transparency of the paint film. It may cause the paint film to be hard and fragile, easy to whiten, burst and fall off. The following describes how to quickly dry old paint in a low temperature environment during decoration.

? One of the solutions of how to quickly dry old paint in low temperature environment: In order to solve the problem of slow drying at low temperature, not only the coating formula needs to be adjusted, but also the construction conditions need to be improved. Adopt winter coating formula to speed up drying. If it still can't meet the transportation requirements of furniture factory, we must use infrared lamp irradiation, warm air pipe and other on-site heating methods to appropriately raise the relative temperature of the environment. These two steps are ideal solutions.

Solution 2: In the low temperature environment, the paint defects caused by slow drying of wood paint spraying include hanging, slow or dry, sticking, undercut, wrinkles, whitening, pinholes, bubbles and so on. When the wind, fog, temperature of 5 degrees and relative humidity of 85 degrees, oil workers stop construction. Lacquer flows slowly due to low temperature drying, resulting in thin and uneven paint film, which is as heavy as hanging curtains and as light as tearing beads.

How to quickly dry old paint at low temperature Solution 3: Use winter thinner to accelerate paint drying; Extend the repainting time until the upper layer of paint is completely dried before painting; Add a little thinner to increase the viscosity of the paint. Appropriately increase the proportion of curing agent (the increase is within 15 inch, otherwise the paint film will become brittle), so as to speed up the curing speed of the paint film; Good ventilation should be ensured to completely release the solvent method and prevent re-adhesion;

Solution 4: Before coating the next layer, the recoating time should be extended until the last layer is completely dry. In order to avoid the primer wrinkling caused by the dissolution of primer diluent when the primer is not cured.

The fifth solution of how to quickly dry old paint in low temperature environment: white low temperature is easy to form water vapor on the surface of substrate, and the relative humidity is 85.

The sixth solution of how to quickly dry old paint; Appropriate extension of repainting time during wet construction. The repainting time shall not be less than 60 minutes and not more than 2 hours, and the wet treatment construction must be carried out at most once. After that, the paint film must be completely dried and polished. Architecture; Cooling water must be cooled for 12 hours before repainting;

Pinholes, bubbles, deep wooden holes and poorly sealed paint on the wood surface slowly dry through the wooden holes to form pinholes; Deep wood holes contain air, paint permeates downward, and air is squeezed out to produce paint bubbles. The above is all the solutions to how to quickly dry old paint in low temperature environment.
