What is the reason for the appearance of rubber particles on the surface of the Pattern Braided Sleeve

Colloidal particles belong to the abnormal quality problem of the product, which will affect the use of the product. After the LED neon Pattern Braided Sleeve is lit, the colloidal part is impurity and will not guide light, so the whole light will be bright, and the glue The grain part is dark, which leads to defective products. The second is to affect the aesthetics. After all, LED neon Pattern Braided Sleeve still have certain requirements for aesthetics as an ornamental and brightening product, and rubber particles are regarded as one of the defects that affect the ornamental.

Why can`t the rubber particles of the woven sleeve with LED neon light patterns be completely eliminated? In terms of the current two-color extrusion process, no one can guarantee that the product will be completely particle-free. We can only try to reduce the occurrence of rubber particles. Why are there less rubber particles in the traditional transparent Pattern Braided Sleeve? During the extrusion process of our silica gel, the single machine head generally adds a filter screen inside the mold to filter out the impurities in the raw materials, so that it will not follow the silica gel. The raw materials are extruded and vulcanized together. The LED neon pattern woven sleeve is extruded by a new type of two-color die head. The mold is generally more precise and the die head is too small, so there is no way to add a filter in front of the mold, which will lead to the appearance of rubber particles on the surface of the LED neon pattern woven sleeve. The probability increases, because the impurities cannot be isolated in the filter screen, so it can only be extruded along the mold to form the so-called colloidal particles on the surface of the casing.
Another method that can be avoided is: in the process of banburying, it is necessary to refine a few more hands, because sometimes the raw materials have air bubbles and dead glue when they are fed. If the mixing time is not long enough, it is easy to cause what Dead glue, these dead glue is wrapped on the surface of the LED neon pattern woven sleeve after being extruded to form dead glue.
Then the solution is: the rubber mixing time must be sufficient and sufficient, and these dead rubber particles are rolled into a colloidal state and extruded together with silica gel, so that there will be no particles on the surface of the woven sleeve with LED neon lights, because the dead glue It is crushed by pressure into powder or gel, and then the dead glue is cracked by vacuuming, so that the appearance of particles can be avoided.
In order to solve the problem from the root, it is necessary to strictly control the raw materials and the workshop environment. Sometimes the products sent by raw material suppliers are not strictly controlled (especially some low-end raw materials), which leads to There is no way to completely solve the particle situation without such control. The second is the workshop environment and the quality of employees. These are one of the reasons for the appearance of particles in LED neon Pattern Braided Sleeve. These can be avoided by making targeted changes to improve the production environment of LED neon Pattern Braided Sleeve.
