A, PU series production matt Note: 1, on the matt varnish gloss. Many factors affecting matt gloss varnish, including coating thickness of paint, paint drying rate, degree of agitation even before spraying, production sites and ventilation air relative humidity production sites are to influence the level of gloss paint . 2, some of the paint because of different solubility, diluent curing agent, different, different thickness of the coating, the film will be on the final performance of the matte evaporation rate, etc. have an impact, so that when you pay attention to pay attention to the production of supporting the use of curing agents, diluents and the like. 3, should be used in different seasons evaporation rate corresponding to the thinner, volatile thinner slow the film is likely to cause flooding, sand. Volatile too fast is likely to cause whitening, loss of gloss, leveling insufficient adhesion poor product quality accidents. 4, winter on the paint. Paint viscosity greatly affected by temperature, the viscosity decreases with increasing temperature, the temperature decreases the viscosity increases. So in the winter can cause diluent to increase the viscosity becomes low, prone to poor fullness, sand, feel the difference, gloss reduction, less able to cover sand marks and other quality problems. So pay attention to the winter storage temperature paint, paint temperature should be kept in place the same temperature. Two, PU series of light production Note 1 because of the relatively long light paint with matte paint drying time, to ensure that the gloss paint surface impurities, and the cleanliness of the closed spray booth more stringent requirements. Also note that when you engage in health, most of them will wash with water sprinkler or room on the ground to dry room, dry room closed because of their own good, relatively high temperature, it will form a hot and humid environment, so that varnish more easily from the dark bubbles. In particular, it is generally recommended that manufacturers will dry room temperature controlled at about 25 degrees, this will pass rate has improved. 2, paste paper or stickers furniture production, processing and closing the paper substrate will affect the choice of primer paint gloss shine, since ordinary PU primer poor solvent resistance, light spray above can lead to a leveling poor, uneven surface gloss and fullness and maintain will be significantly less, therefore, want to get a good mirror effect, the amount of primer appropriate curing agent to increase more, the effect of the surface finish will improved. Third, the production Note 1 PU white finish, in order to make the static surface effect good light white finish, and hope in a long time remain the same, we must start from the choice of MDF, in application experiments contrast, the density fibreboard better, obviously the degree of deformation will be smaller. After a poor finish MDF light flour, put a period of time will be deformed significantly, especially when using PU white will become more powerful, it is proposed in the selection to choose the right MDF MDF. 2, on the primer side, made out of PE white primer gloss white finish either static surface effect is long-shaped extent will be significantly better than the PU primer, particularly in MDF density effect is poor more obvious. 3, prior to spray light white finish, the lower layer of white polish is good, it can directly affect the ultimate effect of light flour and the amount of paint, if used too coarse sandpaper, fullness and static surface effect on surface will become significantly worse if the final go over with a fine sandpaper or play a water mill, can be less when the spray paint spray some white paint, can still get better static surface effect and fullness (individual paint factory white paint curing agent matching requirements are very strict, misuse or abuse of the curing agent affects not only resistance to yellowing, and will significantly change other properties). Third, the production notes on colored transparent paint (also known as a repair process color finish) 1, transparent colored finish is transparent colored. Construction should pay attention to even take the gun, one should not spray too thick, the final color should be sprayed repeatedly made. Otherwise easily lead to uneven color shades, products like the appearance of the affected product. 2, combined with the end of the coloring process, the more three-dimensional effect of film and layering. Fourth, Production Notes Special paint 1, the paint on leather: The leather paint is a special effect paint An art belonging paint, fast drying, high hardness, wear good, the film surface after the hard work was even gritty look and feel, there are kid's feeling. Used in office furniture and cabinets series painting. Usage: Process: Baipi - Closed - sanding -PU solid color primer - sanding --PU solid color primer - sanding - Leather paint. Note: The construction method is basically the same with ordinary polyester paint, grab the spray pressure control during construction, out of fuel, and coating thickness, you can get different leather effects. 2, Cracked paint: the ability to make the film presents a uniform different cracks, good adhesion, according to the thickness of the film will show a different pattern in different sizes. Use: spray paint cracks, general spraying 2 "+", which will cover the entire substrate. Crack paint transferred to suitable viscosity, general spraying a "+" character to achieve the desired pattern, but the workers' individual skill level required for a high number of requests spraying must be uniform, uniform to take the gun. If you need to crack the increase may be appropriate to spray 1-2 "+" character. Note that the last use PU or NC transparent top coat to protect them. Construction Technology: Substrate - filled -NC sanding solid color bottom or gold settled by the (completely covered) - paint cracks or PU topcoat -NC (claim PU spray paint thinner, paint cracks to avoid complete dissolution). Production Notes: A, the right to adjust the spray viscosity (requires consistency as far as possible every time the spray viscosity). B, spraying should be uniform, or the extent of the crack sizes (requiring production of the same suit every spraying the same person, and require workers to high proficiency). C, water can not be gray, putty plaster cracks paint as a primer. D, construction need to pay attention to the use of ancillary products and services. E, due to crack heavy color paint system, paint cracks after construction, to cover clear coat protection. Otherwise there will be back and poor adhesion of the coating defects. G, if the white spray paint cracks should be used in anti-yellowing varnish clear coat, or prone to yellowing. 3, on the pearl paint series: pearl paint with a colorful glitter effect, gloss abundance, elegant color, three-dimensional sense. Usage: pearl paint can be sprayed on a different color primer, the best close to its original color, if you want to get different effects can also be sprayed onto other types of color, which depends on the actual production plant availability . Requirements on the primer coating pearl paint, light grinding hard work after 5 and then use PU clear light overcoat, you will get a high gloss, leveling good mirror effect. Production Notes: A, pearl paint when spraying, with particular attention to the arrangement and density of pearl powder, flash effect is satisfactory. B, when used to stir pearl paint, how many parts pearls directly affect the color and flash effect. C, pearl paint spraying generally do not filter, coarse filter to use when necessary, to avoid the flash pearl paint powder was filtered off (flash powder particles is generally greater than 200 mesh, less than 100 mesh, is too small to affect the flash effect, too affect people's visual effects), the impact of the flash effect. Fifth, on the other 1 PU paint, curing agent: curing agent of foreign products in general are common, only the difference between a primer and topcoat curing agent curing agent. Domestic paint will have much more complex, so production must select the correct curing agent in the country due to differences in different varieties of paint system, the curing agent requirements vary. Note that when using the selection curing agent, or easily cause hardness, gloss, scratch resistance, touch, sweat eliminate uncertainty, additional filling amount of the curing agent must be correct, otherwise it will cause abnormal hardness and gloss . Note: Mistakes should strictly distinguish between the different curing agents and driers in the concept of increase or decrease in the amount of curing agent is not the proper way to adjust the drying rate of the film, reducing the amount of curing agent, the film will have a bad influence. 2, thinner: thinner known as bottom water. Pine fragrance: a high boiling point, slow drying, the solvent is diluted Margulies, a slow-drying solvent has the advantage of easy clean. Slow dry water: It is used to improve the whitening phenomenon due to the high humidity caused by the rainy season. Slow dry water addition for the general control of about 10%, the specific circumstances to data provided by the manufacturer shall prevail.

Do not forget a basic considerations: the spraying process must be careful not to construction work in dusty environment, so as not to affect the final coating results. Trouble the most convenient and most reliable quality and most economical way is to buy finished doors installed directly.
