How to solve the problem of painting wooden furniture with "oil-to-water" (III)

With the transformation of wood coating industry, water-based paint applications have become an irreplaceable part of furniture environmental protection coating, and are gradually being used by more and more people who pay attention to environmental protection and health. In recent years, Dabao water-based paint by virtue of stable quality advantages into the rapid development of the track, water-based wood paint sales are rising, the market share increased year by year. At the same time, Dabao intelligent coating solutions continue to come out, optimize and improve, accelerate the furniture industry to promote the "oil-to-water" process

.
"Oil-to-water" in addition to the previous mentioned in the environmental protection situation spraying system equipment selection and handling and other optimization programs, water-based paint and oil-based paint are two completely different systems, in the furniture coating spraying construction process sprayer will have a completely different operating experience and feelings. Simply say: can spray good oily paint master may not be able to spray good water-like paint Oh! Next small editor for you to share the "oil-to-water" process, Dabao water-powered wood paint spraying problem-solving skills.
Before sharing, it is necessary to know about water-based paint, water-based paint is now synound for healthy and environmentally friendly coating, in the industry water-based paint products are also springing up, mainly acrylic water-based paint and acrylic polyurethane water-based paint two types of pure water-based paint." Acrylic water-based paint for easy construction, mostly used in home furnishings or children's furniture. Acrylic polyurethane water-based paint (commonly known as two-part water-based paint) has excellent materialized properties, hardness, scratch resistance and other performance is better than acrylic water-based paint, so two-part water-based paint is more used in furniture manufacturing enterprises. In practical application, we will find that the water-based paint on the market in the construction spray viscosity is often high, resulting in furniture products after coating paint film effect is not good, the need for furniture factory replacement spraying equipment. Many furniture factories take into account the cost of production and invest in new equipment. Dabao's "oil-to-water" solution has taken into account and solved such problems as the furniture coating transformation.
1, the guest special project water-based wood furniture paint product system
1, the use of low viscosity, high solid content formula design
low viscosity, high-solid content of Dabao water-based paint is fully suitable for customers' existing spray equipment for "oil-to-water", no need to replace the spraying tools, to achieve a better film thickness with low viscosity.
2, open and closed process products introduced
in the process of furniture paint spraying operations often encounter such problems, especially when doing open process effects, sprayers often spray open effects into closed paint effects, spraying amount is very difficult to grasp. Therefore, furniture enterprises in doing high-end products on the sprayer's technology has higher requirements. Invisible also brings a lot of pressure to most sprayers. To say the serious point is to increase the cost of enterprise labor. And Dabao open and closed process products, in the spray method unchanged, just according to product requirements to choose the specified products, sprayer or spray in the conventional way, spray one more shot and less spray one shot as long as the oil does not flow will not affect the final paint effect. Paint film drying paint perforation, feel and work parts of the overall opening effect, paint flatness can be guaranteed, greatly reducing the furniture factory due to changes in technology, spraying method instability caused by furniture coating problems.
3, facade spray anti-flow hanging technology
because water-like paint is the cause of water dilution, drying speed is relatively slow after construction. In the spraying process, a slightly larger amount of coating will occur the phenomenon of drooping. Of course, the actual application of water-based paint can not be sprayed too thick, must be through the multi-channel spraying process to complete the coating of work parts. In general, in order to prevent flow hanging is to add thickener or reduce water addition, but added thickener or reduce water added will improve paint viscosity, not easy to spray out, atomization is not good, wet paint film flatness, pipe hole performance is also poor! And Dabao water-based paint can be done in a lower viscosity, conventional coating amount of facade spraying does not flow, to a certain extent to reduce the paint flow caused by spray construction problems, optimize the water-based paint coating process, reduce the poor coating rate.
4, supporting mechanical automatic spraying equipment
with the improvement of scientific and technological productivity, furniture coating is no longer relying solely on traditional artificial spray production. Now more and more furniture enterprises to introduce modern mechanical automation and efficient coating equipment, such as: intelligent robots, re-injection sprayers, electrostitive sprayers, vacuum sprayers and so on. With a full set of mechanical automation spraying equipment, Dabao paint, has been vigorously invested in this area of technology research and development. The water-based paint product system of the supporting mechanical automatic spraying system has been gradually perfected to meet the needs of the furniture factory for rapid and efficient coating production.
2, the standard standardized water-based paint spraying operation mode
1 clean atomized air
water-based paint in the spray process after spraying the paint surface dry can not be too fast, too fast dry surface will make the water in the paint film volatile, leveling is not good. The transition atomization of the paint mist falls on the newly sprayed paint surface resulting in a rough coating and a poor feel. Among them, one of the main culprits that causes the spray table to dry too fast is that the atomized air pressure is too large, and the excessive flow rate of the air accelerates the drying of the paint surface after spraying. So we have to meet the water-like paint atomization effect while reducing the atomized air pressure as much as possible. Secondly, the atomized air needs to be filtered and purified to reduce the paint film problems caused by the atomized air containing impurities. It is common practice to add oil and water filters and degass valves at the end of the compressed air delivery pipe connection, and to maintain the filter regularly to ensure that the filter is continuously effective.
2 gun position
the gun position operation is not in place, will cause water-like paint oil, shrink edge, orange peel, rough and other issues.the
gun should be perpendicular to the surface of the work piece and maintain a consistent distance (between the spray gun work pieces), maintain a uniform speed of the gun, to maintain the axis of the wrist to reach the end of each gun stroke, to ensure that each stroke begins near the spray work piece outside the pull trigger, and at the end of the trip by the spray work piece of the external release plate machine to complete the gun collection action. Also move on to the start of the next spray trip.
3 folding scale
improper spraying scale will lead to water-like paint film gun marks, uneven gloss, uneven color and other issues.
the spray length of the gun stroke is adjusted accordingly according to the size and shape of the work piece. However, regardless of the width and narrowity of the spray, we need to do is the line gun spray overlay ratio control, to ensure that the gun range and the gun range between the overlay 1/2 to 1/3 ratio.
4-tube
To prevent the supply hose from touching the watery paint during spraying, we should hold the spray gun in one hand and then bypass the hose through the wrist through the shoulder to the back, and grab the bypass hose with the other hand. The hose between the two hands is kept at an appropriate distance so that the arm can move freely during painting operations. If a pressure-feed gun is used, the tracheal and trout pipes need to be tied together with tape so that the pipe and tube winding do not interfere with operation during spraying.
5 position
correct position can relieve job fatigue and improve spray quality and efficiency. Usually the legs are apart wider than the shoulders, in the process of shooting the upper body slightly forward, to ensure that the body's center of gravity is stable, the feet move freely. When spraying higher work parts, a higher platform is required. On production lines at higher flow chain speeds, work pieces must be erred together.
6 Spray order
water-based paint solvent is water without solubility, paint once contaminated is not self-elimination, will directly affect the final surface paint coating effect of water-based paint surface. Therefore, it is also very important for us to use the correct and reasonable order when spraying water-based paint. In general, we have to do the first after the lord, first behind, first behind, from left to right, from back to front, from top to bottom, from inside to outside. Observe the principle that a cycle is not repeated and that it is uninterrupted.
7 coating amount
we often ask: water-like paint how to call spray good, spray enough? To put it actually, the amount of coating is to meet the standard. In principle, the paint sprayed on the work piece after completely moist, do not hang as well. However, the factors affecting the amount of water-based paint coating are related to environmental conditions and the type of drying equipment, in addition to their own factors. In order to avoid paint problems caused by excessive spraying, we will determine the amount of coating on site according to the design requirements, environment and coating production conditions of the customer's furniture coating process.
