Gum belongs to the product anomaly quality problems will affect the use of the product, in the LED neon silicone sleeve light up due to the gum part of the impurities and will not guide the light so there will be the whole light is bright, and the gum part is dark, which leads to the product is bad. Second is to affect the aesthetic, after all, LED neon silicone tube as an ornamental and lighting type products and aesthetic still have certain requirements, and the rubber particles are regarded as one of the defects affecting the ornamental.
Why the LED neon silicone tubing rubber particles can not be completely eliminated? To the current two-color extrusion process to the product is completely no particles who can not guarantee that we can only strive to do to reduce the occurrence of particles. Why is the traditional transparent silicone tube with fewer particles? Our silica gel in the extrusion process in a single head will generally add a filter inside the mold will be raw materials in the impurities filtered out, it will not be extruded with the silica gel raw materials vulcanization molding. LED neon silicone sleeve belongs to the new two-color die head extrusion, its mold is generally more precise and die head is small, so there is no way to add a filter in front of the mold will increase the LED neon silicone sleeve surface particles increase the chances of appearing, because it can not isolate the impurities in the filter, then can only be extruded along with the mold in the surface of the casing to form so-called glue particles.
Another way to avoid is to refine the process of refining a few more hands, because sometimes the raw materials in the feed over when there are bubbles and dead glue, if the refining time is not long enough to lead to the emergence of which dead glue, these dead glue with the extrusion wrapped in the surface of the LED neon silicone casing and thus the formation of dead glue. Then the solution is that the refining of rubber must be sufficient to be long enough, the dead rubber particles crushed into a gel state and silicone molding extrusion, so that the surface of the LED neon silicone tube will not appear particles of the situation, because the dead rubber is crushed by the pressure into a powder or gel and then through the way of vacuum will be the dead rubber cleavage so that you can avoid the emergence of particles of the situation.
To solve the problem from the root cause should come from the material to the workshop environment should have strict control, sometimes the raw material suppliers to send over the product itself is not strictly controlled (especially some low-end raw materials) leads to no matter how to control there is no way to completely solve the case of particles. Secondly, the workshop environment and staff quality these are one of the reasons that lead to the emergence of LED neon silicone tube particles, these targeted changes will be LED neon silicone tube to improve the production environment can be avoided in such cases.
