Examples
Embodiment 1
[0033] Put the medium-alkali glass balls into the glass melting pool of the vertical glass fiber drawing device, the temperature of the melting pool is 1350°C, and the drain plate is used for drawing instead of platinum, and the temperature of the drain plate is 1150°C. At a pulling speed of 1500 m / min, the glass droplet is drawn through the leak hole to draw 45 long fibers, and the fiber is coated with a polytetrafluoroethylene coating through a roll-type "oiler" at a temperature of 350 ° C. The coating thickness is about 0.1 to 0.5 μm. And then through 300 ℃ hot melt setting. Then it is coated with spinning lubricant through the lubricating liquid tank, and finally wound on the reel to make Botelon fiber.
[0034] After unwinding, spinning, and packing the botelon fiber reel, it can leave the factory, or enter the weaving workshop to weave it into high-temperature filter cloth or base cloth.
Embodiment 2
[0036] Will image 3 The medium-alkali glass melt in the medium-glass melting pool is drawn out from the leak nozzle on the wire-drawing sink plate with a temperature of 1150°C, and passed through a polyimide paint dipping tank at a temperature of 500°C to make a cross-section such as figure 1 The thickness of the impregnated polyimide coating is about 0.2-0.4μm. After heat setting at 400°C and coating with spinning lubricant, it is finally wound on a spinning reel by a winding device.
[0037] The Botelon fiber on the reel is chopped, spun and woven to make high-temperature filter cloth or base cloth. It can also be made into needle-punched felt by carding, stacking, needle-punching, singeing and other processes after chopping, which can be used as high-temperature filter material.
Embodiment 3
[0039] Put the alkali-free glass balls into the melting pool of the vertical wire drawing device. The temperature of the melting pool is about 1400°C. Platinum-rhodium alloy drain plate is used with a plate surface temperature of 1250°C. It is drawn into 80 long fibers at a pulling speed of 2000 m / min. The fiber is coated with polybenzoxazole coating by a roll-type "oiler" at 550°C, and the thickness of the coating is 0.3 μm. After the Botelon fiber is made, it is heat-melted at 500°C, coated with spinning lubricant, and wound into a tube.
[0040] Filament unwinding, spinning, and weaving can be made into high-temperature filter cloth or base cloth.
