What is the Advantage and Disadvantage of Tape Coating Machine

1. Production process (coating)

View Details

Coating a layer of butyl acrylate pressure-sensitive adhesive on BOPP, the production process is called coating, which is quite simple!

2. Base information of the coating machine

The size of the coating machine is relatively large, and the coating machines on the market are not only different in width, but also in length due to different design speeds. According to statistical data, there are currently 0.5m, 1m, 1.3m and 1.6m domestic coating machines, among which 1.3m is the most common, accounting for about 80% of the national use; 0.5m and 1m are mostly manufacturers It is used for printing and printing tape; the 1.6-meter coating machine has only gradually flourished in recent years. The length of the coating machine is 30-40 meters (designed for drying glue).

3. Coating process (squeegee + wire rod)

The coating machine has two coating processes, wire bar and doctor blade. The doctor blade is a traditional coating process. Its advantages are: it can obtain high smoothness and gloss; its disadvantages are: it has higher requirements on the original film and the glue coating speed is relatively slow. As a coating process that has just emerged in recent years, wire rod has the advantages of low requirements on the original film, fast glue coating speed, and can adapt to coating with high solid content; the disadvantage is that the adjustable range of coating amount is small , the metering rod is easily damaged, and the quality of the glue is high. Each craft has its own shining point, the two crafts can only coexist, and neither of them can be eliminated.

4. Coating speed (process differences)

The production process of the coating machine is divided into the wire bar process and the scraper process. Generally speaking, the production speed of the wire bar machine is faster than that of the scraper machine. According to statistics, the current production speed of the wire rod machine is 250-260 m/min, 280-290 m/min, some can reach more than 300 m/min; while the production speed of the scraper machine is 220-230 m/min, 180-190 m/min, 150 m/min, and even some old lines around 100 m/min. Therefore, the production capacity of each coating machine is quite different.

5.the specific steps of tape production

&#;Adding raw materials: The first thing to do in the tape production process is to add tape raw materials, such as acrylic acid.

&#; Emulsification tank: Then add the acrylic tape raw material to the emulsification tank for emulsification.

&#;Reaction pot: Add acrylic acid into the emulsification tank for emulsification, and then put it into the reaction pot for heating.

&#; Glue: After the above tape production process steps, the finished glue is produced.

&#; Coating machine: Put the newly made glue on the film for gluing.

&#; Semi-finished products: tape semi-finished products made through these tape production processes - parent rolls.

&#;Pipe cutting machine: use the pipe cutting machine to carry out the pipe cutting process on the tape parent roll just made.

&#; Slitting machine: After the tape master roll is successfully cut, the tape production process is carried out by a slitting machine.

&#;Carton: After the tape master roll has been cut into tubes and strips, it becomes the tape that people see in the market, and now it can be packed in cartons.

&#;Adhesive Tape: Put the packaged adhesive tape in the warehouse, this is the last adhesive tape production process, at this time it can be called the finished adhesive tape.

BOPP sealing tape machine can automatically rag at high speed. Its advantages are high-speed automatic cloth cutting, automatic film sticking, automatic edge trimming, uniform glue coating, etc. With the gradual development and expansion of the sealing tape market, the application range of the sealing tape coating machine is also expanding.

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.
