Waterproof film, also known as waterproof and dust-proof net, is mainly used in acoustic applications. It can provide a shielding effect for waterproof and dust-proof pollution, and has good sound wave transmission. They can also prevent dust, splashing, ordinary beverages such as soda and coffee from briefly falling into the water, and provide pressure relief and balance. Provide a solution to protect the unobstructed pressure relief holes without significantly restricting air exchange. The control of these holes is necessary due to pressure fluctuations in the equipment caused by temperature, altitude, and sound pressure changes, as well as the release of battery exhaust gas. Its advantage is that it can withstand high temperatures up to 250 ℃ and low temperatures down to -196 ℃.

The biggest feature of waterproof and dustproof mesh is that it is a very good sealing product, with a waterproof level of IP67 (the product is placed in 1 meter deep water, soaked for 30 minutes, without water ingress), and meets SGS and ROHS environmental standards. Moreover, waterproof and dustproof nets also have the following different characteristics. Let's take a look together:

1. Waterproof and dustproof mesh can prevent dust: Although it is not possible to completely prevent dust from entering, it can effectively block dust outside the product over time, or even a small amount of dust entering will not affect the normal operation of the equipment.

2. The waterproof and dustproof net can protect solid foreign objects with a diameter of 2.5mm and larger. Tools, metal wires, etc. with a protective diameter or thickness exceeding 2.5mm.

3. The waterproof and dustproof net can protect against splashing water and water droplets. It can be said that water droplets falling vertically will not cause damage.

4. Waterproof and dustproof nets can effectively protect against water immersion. When immersed in water under certain pressure and time, it will not cause damage to the intrusion of water.

5. Waterproof and dustproof nets can protect against water flooding. The equipment can be immersed in water for a long time under the conditions specified by the manufacturer.

In fact, the most commonly used waterproof and dust-proof mesh materials in the die-cutting industry are mostly Italy's SAATI and Japan's SEFAR waterproof mesh, which have black and white colors. During die-cutting processing, there may be situations where the waterproof mesh of the mesh is not firmly adhered to the adhesive, which may occur during the layering process after punching; Later, after analysis, 3M double-sided adhesive was used, and 3M467/468 double-sided adhesive can solve the adhesive problem. Secondly, during the production process, if the pressure on the pressing wheel is not enough, it may not stick firmly. Just add a little pressure.
