& nbsp; In the field of mobile phone screen repair, screen adhesion is crucial, but vacuum bonding machines also need to pay attention to details when removing bubbles. Although removing bubbles is a very, very simple process, many situations where bubbles cannot be removed without attention can also occur. For example, issues such as setting the time too short. Have friends who are familiar with the process of repairing mobile phone screen bursts encountered situations where bubbles are difficult to remove when making screens?
& nbsp; In the eyes of many people, defoaming is a simple task, but in fact, using a defoamer also requires skills. So how did you solve those stubborn little bubbles when you encountered them? The editor has summarized it for everyone today.
In our daily use of defoamers, we need to pay attention to the following points:
1： The temperature of the defoamer.
& nbsp; When using a defoamer, the temperature inside the defoamer should be set between 35-45 degrees. Some prefer to use a defoamer with a temperature above 50 degrees, and the temperature can be set according to the quality of the OCA adhesive used. The temperature of a good defoamer should not exceed 50 degrees. If the temperature inside the defoamer is too high during use, the probability of defoaming will increase, so the ideal temperature is between 30-50. A good choice for the working pressure of the defoamer is between 6-8 MPa.
2： Stubborn small bubbles
& nbsp; For some stubborn small bubbles, most people think that it is due to insufficient time or pressure for bubble removal. In fact, there are other reasons for this situation. Those familiar with the screen making industry know that when making screens, they will encounter bubbles that are difficult to remove to some extent. In this case, if you want to redo it, you need to consider the cost/time issue. So when encountering stubborn bubbles, you can use a clamp to clamp them and remove them.
& nbsp; When using a defoamer, it is necessary to pay attention to whether the door of the defoamer is locked properly, because the defoamer works under high pressure, so it is necessary to pay attention to the safety of using the defoamer.
& nbsp; Shandong Tianyuan is a chemical company that integrates research and development, design, manufacturing, installation, and commissioning of defoaming equipment. The company has several technical design engineers and production personnel, using processes and technologies; We have successfully designed and produced various series and specifications of defoaming equipment, including fully automatic defoamers, semi-automatic defoamers, and experimental defoamers.
& nbsp; High pressure defoamer is Tianyuan's main product, which has complete specifications and is available in high, medium, and low grades. According to different user requirements, the products are made of all stainless steel, some stainless steel, and carbon steel. The control system is operated by a microcomputer and touch screen, which can achieve automatic control of the entire defoaming process. Easy to operate, good defoaming effect, and convenient maintenance. And we can design and customize various specifications of equipment for users.
