BOPP tape coating machine

1. Production process (coating)
Painting a layer of acrylics on the BOPP to compress the allergic glue, the production process is called coating, which is quite simple!

2. Know the coating machine
The coating machine has a large size. The coating machine on the market not only has a difference in width, but also has a difference in length due to different design speeds. According to statistics, domestic coating machines are currently 0.5 meters, 1 meters, 1.3 meters, and 1.6 meters. Among them, 1.3 meters are the most common, accounting for about 80%of the nation's usage; It is used to make prints and printed tapes; 1.6 meters of coating machines have gradually flourished in recent years. The length of the coating machine is 30-40 meters (design for drying glue).

3. coating process (scraper+line stick)
There are two coating processes of the coating machine, which are thread rods and scrapes. The scraper is a traditional coating process. Its advantage is that it can obtain higher smoothness and gloss; the disadvantage is that the requirements for the original membrane are higher, and the speed of the glue is relatively slow. As a coating process that has just emerged in recent years, its advantages are: low requirements for the original membrane, faster glue, and coating that can adapt to high -solid content; the disadvantage is: the adjustable amount of coating can be adjusted in small range. The measurement stick is prone to damage, and the quality of glue is high. Each process has the flash point of each process. The two processes can only coexist and cannot be eliminated.

4. coating speed (different process)
The production process of the coating machine is divided into line sticks and spatula techniques. Generally speaking, the linear machine is faster than the production speed of the spatula machine. According to statistics, the current production speed of the linear machine is 250-260 meters per minute, 280-290 meters/minute, and some can be more than 300 meters per minute. 180-190 meters/minute, 150 meters/minute, and even some old lines are about 100 meters per minute. Therefore, the production capacity of each coating machine is quite different.

5. Specific steps for tape production
1. Added raw materials: The first thing to do in the process of tape is to add tape raw materials, such as acrylic.
2. Emulsion groove: then add acrylic raw material to emulsification.
3. The reaction cooker: The acrylic is added to the emulsification groove for emulsification, and then puts it in the reaction cooker for heating.
4. Globe: Production of glue products after the above tape production process steps.
5, coating machine: put the newly made of glue in the film for glue.
6, semi -finished product: tape semi -finished products made through these tape production processes -mother rolls.
7. Tube cutting machine: The tape -cutting machine that has just been made is used for tube cutting process.
8. Sub -machine: After the tape's mother roll is successfully tube, a split machine is used for a split tape production process.
9, carton: tape mother rolls have become tapes seen by people in the market after cutting and bounty. Now they can be packaged.
10. Tape: Place the packed tape in the warehouse. This is the last tape production process. At this time, it can be called the finished product.

BOPP sealing band machines can automatically break the cloth automatically. Its advantages are high -speed automatic cloth, automatic film, automatic edge, and even glue. With the gradual development and expansion of the sealing tape market, the scope of application of seal tape coating machines is also expanding.
