How to solve the problem if the silicone tube of the neck hanging fan adsorbs hair?

     As the weather gets hotter and hotter, whether it is the kitchen, office workers or all walks of life, they all want to be equipped with a movable fan. The hanging neck fan is developed on this basis. There will be a section at the end of the hanging neck fan. The hose supports 360° kinks and can adjust the wind direction arbitrarily. A layer of silicone tube will be wrapped outside this section of hose to cover the main hardware. The hose has the functions of beautification, softness and comfort. Without special treatment, it is easy to stick to dust, absorb hair and other shortcomings, and the neck fan is very close to the hair, and all these shortcomings are magnified, so it is necessary not only for the soft, safe and comfortable silicone tube of the neck fan, but also for the neck fan Silicone tubes cannot absorb hair and impurities, and the current solution is: oil spray and special pockmarked surface treatment.
     Solution: oil injection: oil injection can completely solve the problem of adsorption and stickiness on the surface of the silicone tube of the hanging neck fan, but it will increase the cost correspondingly. After all, the surface of the silicone tube needs to be treated with ink. The principle is that the surface of the silicone tube Carry out all-round wrapping to make it sticky and adsorbable. This kind of hand feeling and oil isolation is to add a door between the two so that the silica gel adsorption force is isolated from the silica gel body and cannot be released. This solution can not only solve the problem of absorbing hair and dust, but also It can increase the affinity between the silicone tube and the human skin, making people feel more comfortable. In addition, the silicone tube is bright in color (various and colorful can be customized). The neck fan silicone tube, once the tube is sprayed with oil, can completely solve the problem of absorbing hair and sticking dust.
     Another solution that is not very practical but is also used by some groups is to reduce the adsorption capacity and dust sticking characteristics of silica gel from the process. First, adjust the hardness of the silicone tube of the hanging neck fan to about 40~50°. It is not suitable for high hardness. The reason for this is that the hardness of the raw material of this method is relatively low. No oil injection is required through extrusion molding, and the surface will appear uneven. The appearance is a bit grainy, a bit like a defective product but not a defective product. This is intentionally made into this kind of grainy surface. The advantage of this is that each pit can pass through these uneven pits With subtle heights and troughs, these pits can weaken the adsorption capacity of silica gel (note that it is weakened rather than completely absent). The advantage of this is that it can greatly weaken the ability of the silicone tube of the hanging neck fan to absorb hair, so that it can be done without Oil injection can weaken the adsorption capacity of sticky dust. From another perspective, the cost of the silicone tube of the hanging neck fan is reduced a lot. This is why many companies in the market have to choose this method because they want to control the cost of hanging neck fans. , although this method reduces the adsorption capacity, it will also lose part of the feel of the silicone tube of the neck fan.
