Characteristics of several coating methods -

Wire scraper
These scrapers are made of high-precision cold-drawn round steel wrapped around stainless steel wire. If the wire scraper is rotated by the micro DC motor during the scraping, the effect is better. The wire scraper usually acts directly on the substrate when the glue is applied. However, it is generally only used for the pre-squeegee coating of the smooth roll. A precise squeegee of a comma blade is usually required later.

Air squeegee
The air squeegee mechanism acts on the sizing roller by a uniformly sprayed gas (pressure) flow, which serves the purpose of squeegeeing. The gas (pressure) flow is required to be evenly distributed over the entire width of the optical roll, and this type of scraper is often used for scraping a good fluidity. The scraper has a high precision of scraping, and is currently widely used for coating scraping of whiteboard paper.

Various optical films, protective films, film films, matte flexible packaging films.


Slot-Die Coating:
     The Slot Die coater is a high-precision coating method in which the coating glue is pressed from the reservoir to the nozzle through the supply line, and the glue is ejected from the nozzle to be transferred to the coated substrate.
advantage:
1. The coating effect is good, and the coating amount is flexibly controlled by the micro-motion adjustment of the coating blade, and the coating precision is high.
2. It can coat the discontinuous mode, and the coating range can be adjusted freely. It does not need to use the baffle plate, and it will not produce the stain phenomenon caused by the difference in edge thickness.
3. Cleaning and disassembly is easier.
4. Helps to maintain a clean, high level, the channel through which the glue flows as a whole can be sealed to prevent the entry of other contaminants.
Disadvantages:
1. The partial structure of the entire Slot-die coating head is complicated, and the processing precision of the rubber roller, the coating roller, the traction roller and the scraper is required to be high, so the cost is higher than other coating methods.
2. Due to the high precision, it is difficult to use and operate.
