Home wood decoration and life are closely related, pay attention to the choice of paint.
1, UV paint quality on the impact of wood quality UV paint is a kind of radiation curing coating, is an environmentally friendly energy-saving paint, with UV paint finish wood floor paint film hard, wear-resistant, high light paint bright plump, delicate matte paint Smooth.
UV lacquer cures quickly and reaches surface dryness within a few seconds in a few seconds by ultraviolet radiation. When the coating film is dried by a wet film, the shrinkage thereof is large and the internal stress is large, so that the adhesion between the coatings is poor. The hardness of UV paint is generally stronger than that of other paints. Generally, the harder the paint film, the more brittle the paint is. The less wear resistant, the paint film is also easy to crack. When the hardness of the coating film is noisy, the change of the surface paint film can not be deformed due to the lack of elasticity due to the thermal expansion and contraction of the floor or the change of wet shrinkage and shrinkage, and cracks appear.
2. The effect of PU lacquer quality on wood quality PU lacquer and polyurethane lacquer can enable star hydrogen bonding between polymer molecules. When the external force acts on the coating film, the hydrogen bonds can be separated and the external energy can be absorbed. When the external force is removed, the film is re-formed into hydrogen bonds to form a reversible repetition. The PU paint has high mechanical wear resistance and toughness.
PU paint film adhesion is good, has excellent adhesion to all surfaces, in particular, has a good sealing effect. It can be dried at high temperature and can also be cured at low temperature. It can be cured even at 0°C, and has good solvent resistance and chemical resistance. Each paint needs to dry before it can be used for the next painting process. It has a long time and low efficiency, but it has good sealing effect on oily floors, especially with good toughness. Therefore, the paint cracking, wrinkling, etc. caused by the deformation of the floor deformation caused the damage of the paint film to be smaller than that of the UV paint.
However, due to the fact that PU paint has a certain amount of volatile gases such as benzene, it contains a large number of highly active isocyanate groups, it is easily gelled in the presence of water or moisture, and construction operations inadvertently cause interlayer peeling, film foaming, and other disadvantages. . At the same time, the PU coating containing aromatic isocyanic acid was yellow after being irradiated with ultraviolet rays, and had poor light retention and color retention. Therefore, we must strictly guarantee the quality of PU paint, and master the correct operation method, so as to ensure the quality of the wood.
Therefore, the quality of the coating must be strictly controlled during the coating process so as to ensure the overall quality of the wood.
