The curtain film of the curtain coater is generated by the pressure of the diaphragm pump, the thickness is easy to adjust, and the distribution is uniform, and the thickness of the paint surface is not different; the conveying speed during the curtain coating can reach 80m/min, so that the paint on the surface of the wood is evenly reduced. The coating thickness of the paint. Analysis of the cause of pitting on the surface of the coating machine?
1. UV dryer equipment is widely used in many other fields such as electronics, optical fiber, liquid crystal display, printing, packaging and so on. Such as: scanning, packaging carton picture offset printing, nameplates, desk calendars, wall calendars and other UV curing inks, various business cards, calendar nameplates UV curing, a large cardboard drying curing equipment UV varnish. 2. Small electronic plastic hardware UV glue or UV curing ink, electronics, precision parts, magnetic heads, magnetic material optical sheets, liquid crystal displays, micro motors and UV light curing adhesives curing, liquid crystal display glass edge sealing UV adhesive curing equipment.
1. Put the UV coating of the roller coater into the product: put the object to be coated on the insert of the roller coater and start working; 2. Electrostatic dust removal: remove the oil and dust brought by injection molding; 3. Preheat: for more Good coloring gives the object a little temperature; 4. Primer spraying: cover the color of the plastic itself, and spray the base color first for the color required for production;
The working principle and structure of the sprayer end? The main working part of the spraying machine is a double-acting pneumatic hydraulic booster pump, and the reversing mechanism is a special form of pilot fully air-controlled air distribution reversing device. After entering the compressed air, when the piston moves to the upper or lower end of the cylinder, the upper pilot valve or the lower pilot valve is actuated, and the air flow is controlled to instantly push the air distribution reversing device to reverse, so that the piston of the air motor makes a stable and continuous reciprocating motion .
What are the product characteristics of UV roller coater? UV roller coater is also called full precision roller coater. It is named because the conveying system, uniform paint roller, and uniform steel roller system all need to precisely adjust the running speed. Reasonable adjustment and use can make the UV paint surface even and even. , High production efficiency, low paint loss, so it has been widely promoted and used in the furniture manufacturing industry, bamboo and wood crafts manufacturing industry, floor wall panel industry, and slippers production industry.
What is the solution to the poor defoaming performance of the curtain coater? The UV coating formulation is improper or the storage temperature is too high, the storage time is too long, and the ultraviolet light will leak. The following points: 1. Choose UV topcoat with good defoaming properties. 2. A filling back cover should be fully sealed, and no small gaps should be left. 3. Try to avoid working at high temperature for paint, curing machine and leveling machine, which will cause the substrate temperature to be too high (not exceeding 60℃), which will cause air to expand and escape.
