Five kinds of high transparent Slant Silicone Brush Tube making mold process
The Slant Silicone Brush Tube is a processed work made of silicone as the main raw material. Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier.
The adsorption of silica gel is mainly physical adsorption, which can be regenerated and reused. Add acid to the alkali metal silicate (such as sodium silicate) solution to make it acidify, and then add a certain amount of electrolyte to stir to form silicic acid gel; or add acid or Ammonium salts can also generate silica gel. Let the silicic acid gel stand for a few hours to age it, then wash it with hot water to remove the soluble salts, dry it at 60-70℃ and activate it at about 300℃ to obtain silica gel. The silicic acid gel is soaked in a cobalt chloride solution and then dried and activated to obtain color-changing silica gel. The Slant Silicone Brush Tube made of silicone also has this characteristic.
The Slant Silicone Brush Tube can be made into a translucent state. I believe everyone knows that silica gel can become completely transparent. Can also achieve high transparency, transparency and glass transparency comparable. So, how is this highly transparent Slant Silicone Brush Tube made?
If you want to make a high-transparency Slant Silicone Brush Tube, first of all, the silicone mold must be made, and the mold must be polished. Mold polishing can be divided into multiple processes. Here are five common processes:
Electrolytic polishing is to use a small protrusion to selectively dissolve the surface of the material to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better, and the surface roughness can reach Ra<1μm.
Mechanical polishing is a polishing method to obtain a smooth Slant Silicone Brush Tube surface through plastic deformation of the surface of the cutting material. Generally, oil stone strips, wool wheels, sandpaper, etc. are used, mainly manual operations. The ultra-fine polishing method can be used for high surface quality requirements. The surface roughness of this technology can reach Ra0.008μm, which is the highest in the polishing process.
Ultrasonic polishing is a polishing method that uses ultrasound as the power to impact small abrasive particles on the surface of the workpiece at a very high speed, forcing the abrasive to process the processed surface, thereby reducing the surface roughness of the inclined silicone brush tube.
Liquid polishing relies on the high-speed flow of liquid and the abrasive particles it carries to clean the surface of the workpiece to achieve the purpose of polishing. Commonly used polishing methods are: abrasive jet processing, liquid injection processing, hydrodynamic grinding and so on. Hydrodynamic grinding is driven by hydraulic pressure, so the liquid medium carrying abrasive particles flows over the surface of the inclined silicone brush tube at high speed.
Magnetic grinding and polishing:
Magnetic grinding and polishing is an abrasive brush formed by magnetic abrasives under the action of a magnetic field. After grinding and processing, the work piece has the advantages of high processing efficiency, good quality, easy control of processing conditions, and good working conditions. Under proper abrasive conditions, the surface The roughness can reach Ra0.1μm.
After the mold is polished, at this time, it is not possible to directly produce a completely highly transparent Slant Silicone Brush Tube. The raw material of the silicone also needs to choose a highly transparent silicone material to make the manufactured Slant Silicone Brush Tube have high transparency.
