In the manufacturing process of sound horn, how to bond the rubber diaphragm sound film to the ABS shell is an important technical link.
 In the past, the use of oily glue bonding brought the problem of environmental protection has attracted more and more attention of users, and this kind of glue is rigid, elasticity is not enough, but also limits the effect of diaphragm sound membrane assembly. This paper will introduce the bonding technique of rubber diaphragm sound membrane by using ENIENT diaphragm film and ABS shell.

 First, choosing the appropriate adhesive is the key to ensure the bonding effect. This innovative water-based adhesive can fuse well with the rubber and the ABS shell, and strengthen the weak edge, which only requires a very short curing time, which is due to the addition of special reaction promoters, so that the water-based adhesive has the same rapid curing characteristics. This glue has 1200% fracture elongation, and the film is uniform and dense, with good sealing and insulation, can withstand deep water immersion, high temperature aging experiment, water boiling experiment and other strict standards. With good adhesion and mechanical fatigue resistance and weather resistance, can long time to meet the requirements of sound film and shell in long-term vibration movement.

 How exactly do we use this glue?
 
 Prepare the work before bonding first. First of all, ensure that the rubber diaphragm sound film and ABS shell surface are clean and dry, free of dust and grease. It can be cleaned with solvents such as detergent and ethanol, and then dried with a clean cloth.

 Then, apply the innovative water-based glue. The innovative water adhesive is evenly applied to the joint surface of the rubber diaphragm sound membrane and the ABS shell. Pay attention to avoid applying too thick or too thin, in order to ensure the sound effect.

 Subsequently, a period was waited to allow the glue to form a uniform film on the contact surface. This process can be fixed using a clamp or clip, ensuring that the glue maintains the appropriate pressure during curing.

 After the bonding is complete, you need to wait for the glue to cure adequately. The curing time should also depend on the specific ambient temperature and humidity. During the curing process, vibration and forces should be avoided.
 
It is worth mentioning that during the whole construction process, there is almost no odor, so the whole working environment is safe and comfortable. It is also more suitable for the modern dust-free clean workshop with low odor requirements.

 Overall, the use of EG 206 adhesive rubber diaphragm sound film and ABS shell is a stable and reliable method to meet the high quality requirements. By selecting the adhesive and following the correct bonding steps, the adhesive can improve the quality of the horn. Hope the above tips will help you.
