There are many kinds of products that coat the production and production, from the shadow of people's livelihood supplies to cutting-edge technology, especially when producing high-precision coating products, we need to carry out high quality volume of coating technology technology, we focus on Introduction to three common precision coating skills, line comparison, for reference.
• 15% of equipment technology (Equipment)
First, small distension coating
The microplexing coated coated is netizen, and the diameter is generally at 120mm- (between D50mm, so it is called micro gravure coating, which is a direction, contactless coating method, the direction of rotation of micro-coating In contrast, the film is not pressed against the coating. The traditional gravure coating method, whether directly coating or reverse coating, back pressure rubber, and rubber diameter The substantially the same row of ribbed is suspended because the material film is pressed between rubber mixing and mesh, it is likely that there is a wrinkle, cracks such as wrinkles and cracks in the coating surface, and the two-in-pressure contact points are coated due to mechanical, air pressure. The quality of the cloth is affected. The micro gravure coating is a method of coating M-style, which means that there is no back pressure rubber homewhere, so some potential hypothyrin produced due to back pressure is eliminated.
• The reverse coating can obtain a relatively flat coating, and the coating amount is evenly distributed.
• Micro gravure coated supply is more complicated, cleaning, and disassembling dagger, often takes 1 · 2 hours.
Shading film, various optical films, lithium batteries, various composite tape, Philippine film, protective film.
The comma-coated coating is characterized by a combination of blade scraper and mixed blade. The impact of the glue thickness is smaller than the blade, the thickness of the coating is easy to adjust, and high viscosity gum can be applied. When the width is large, it is possible to adjust laterally.
• When the coating can be coated, when the coating is applied, the collapse is from the upper and lower flow to the blades and the film film, so that the glue can be sufficiently used, and there is substantially no waste of the plastic liquid.
• Commercing coated coating quality and its various components have a large operation relationship, especially for driving motors and rotating the transmissions of the mushroom, often causes uneven coating, easy to appear horizontally or portrait When the irregular stripes, when coating, the gum is easily out of the baffle and the gap between the transmission, the sealing property is not complete, and when the coating is applied, it is necessary to manpower constantly withdraw the glue of the semi-storage tank. To ensure a uniform distribution of the collapse. Commerges coated application of various optical films, protective film, Philippine forest film, matte soft packaging film.
Slip extrusion coater is a common high-precision coating method, and the coating collapse is sent from the memory to the nozzle by the supply pipeline pressure, and the collapse is ejected from the nozzle, thereby transferring to coating Substrate.
• It helps to maintain a clean level, the channel of the overall flow of the collant can be sealed, and the entry of the pollutants can be sealed.
• Due to high precision, actual use and difficult operation.
High-end optical film, window film, special name for high end membrane.
The so-called roll-to-roll precision coating technology can be applied to various industries such as IC, PCB, photoelectric, people's livelihood, and medical care, from the product (such as stationery tape) to medical tape (beauty, healing) To electronic tape (IC cutting, PCB soldering), as well as photoelectric tape (optical glue with LCD), etc., is a product developed by precision coating technology platform.
It is a coating technique that presses and transfers the coating along the mixed slide along the mixed slide, which is fast, the coating film is width, etc. Features, representing the future direction of wet coating
Advantages: High coating film; good film thickness; wide ladc scale; coating defect (closed loop system); high coating utilization; multilayer coating can be carried out simultaneously.
