Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of glass fiber tube production, in particular to an environment-friendly glass fiber sleeve gluing and coating device.
[ background of the invention ]

After the glass fiber pipe is woven and formed, the outer wall of the pipe needs to be coated with coating oil, so that the comprehensive performance of the glass fiber sleeve is enhanced. In the existing gluing process of the gluing tank of the silica gel glass fiber sleeve, xylene is diluted, silica gel liquid containing xylene is added into the gluing tank, a layer of silica gel containing xylene solvent is coated on a glass fiber blank tube through the gluing tank, and the silica gel is uniformly covered by utilizing the action of gravity. The xylene content of the used silica gel raw material is 40-50%, and the xylene content of part of the silica gel raw material is over 70%. In the subsequent long drying tunnel vulcanization process at 100-250 ℃, the xylene organic solvent is completely volatilized and discharged into the atmosphere, and the environment is seriously polluted. And the silica gel layer on the surface of the glass fiber sleeve after the diluted xylene silica gel liquid is coated at one time is thinner, so that the breakdown voltage and the flexibility of the product are poorer. Even if silica gel liquid without xylene is used, the viscosity of the silica gel liquid is higher than 10000mPa & S, while the viscosity of the silica gel liquid diluted by xylene is below 800mPa & S, the coated silica gel liquid naturally sags and flows under the action of gravity, so that the thickness of the sections of different areas of the glass fiber casing is very uneven, and the glass fiber casing has no practical use performance; if the viscosity of the solvent-free silica gel is reduced, the overall performance of the silica gel liquid is reduced, and the prepared glass fiber casing is very hard and brittle and is very easy to break. The existing gluing process adopts a mode of immersing and hanging coating liquid, and the requirements of the existing production process are not met.

In the traditional coating process, the blank tube is soaked in silica gel liquid added with dimethylbenzene, and the coating thickness of the surface of the blank tube is not uniform due to the liquidity of the silica gel liquid after the blank tube penetrates out of the silica gel liquid; and the xylene has volatile pollution and can volatilize under the high-temperature baking of a subsequent vulcanizing furnace. Even if xylene is not added, the coating thickness of the surface of the embryonic tube is more difficult to control due to the higher viscosity of the silicone fluid. According to the sizing coating device 3 provided by the invention, the blank tube subjected to dewaxing treatment is pulled to the upper port of the sizing coating device 3 to be subjected to dewaxing treatment, the blank tube is pulled out from the lower port of the sizing coating device 3 in the substantially vertical direction to finish the process of coating the surface with the silica gel liquid at one time, and the silica gel liquid in the sizing coating device 3 can be uniformly coated on the surface of the blank tube to form the sleeve 10' without adding xylene; the tube coated with the silica gel liquid is vulcanized in a high-temperature vulcanizing furnace 4 and a secondary vulcanizing furnace 5, pulled by a tractor 6, wound on a winder 8 after passing through a tension wire storage frame 7.
