    1485184 Glass fibre manufacture KAISER GLASS FIBER CORP and NITTO BOSEKI CO Ltd 13 Jan 1975 [14 Jan 1974 26 Aug 1974] 1329/75 Heading C1M Glass fibres 12 are formed by passing molten glass 14 through orifices 22 in a plate 38, the orifices opening to and terminating at the plate, and directing a flow of gas on to the external surface of the orifice plate so that the plate is cooled sufficiently to prevent flooding and eliminate stagnate gas from adjacent the plate. The gas is directed at an angle of 45 to 90 degrees to the plate. The gas should be non- reducing and is preferably air, nitrogen or carbon dioxide. The orifices are formed in the plate at a density of at least 50 per square inch, those on the periphery of the plate having a larger diameter. The orifices may be interconnected by capillary grooves. To regulate the head of glass a reservoir is provided communicating with a supply of glass via a valve, the latter being actuated by a depth gauge in the reservoir.

    (54) METHOD OF MANUFACTURING GLASS FIBER
    AND DEVICE FOR ITS IMPLEMENTATION
    one
    The invention relates to the production of glass fibers, namely to methods and devices for the production of glass fibers.
    A known method of manufacturing glass-5 fibers, in which fibers are drawn from a stream of molten glass mass that is passed through filters, is fed into the exit zone of a glass-cone stream from a film {aa cooling slurry in the form of a continuous jet and discharges it l.
    It is also known a device for carrying out this method, comprising a container for melting glass mass, a flat plate die with holes 5 located at the base of the tank, means for drawing glass fibers and means for supplying and discharging a cooling gas medium .1.
    However, the glass fiber obtained by this method is of insufficient quality.
    The purpose of the invention is to improve the quality of the fibers by preventing the inlet of the spinnerets with molten glass.
    The goal is achieved in that according to the method of making glass fibers, in which fibers are drawn from a stream of molten glass mass that is passed through dies, the cooling medium is introduced into the exit area of the glass cones from (| As a continuous stream of gas, it is constantly directed to the exit zone of the glass cones from the spinneret at an angle of 46-9 ° from at least one side of the stream of glass cones.
    In addition, in an apparatus for carrying out the method of manufacturing glass glasses, the cooling gas medium supply means C comprises a gas nozzle located under the plate with holes at a distance of 2.5-51 cm.

    FIG. 1 shows the device for the implementation of the proposed method, a general view ;, FIG. 2 - plastag with holes, side view; in fig. 3 - the same, raerez. The device comprises a reservoir 1 for melting glass mass. Tank 1 was crushed in sleeve 2, in the center of which head 3 with molten glass was placed. Tank I has a base 4 and can be made of kvasfatnym, right coal or dilinaric. At the base 4 of tank 1 there is a filter-. Pa in the form of a plate 5 with holes 6. Above the sleeve 2 is placed a means for extracting glass fibers in the form of a valve 7, by means of which the inside of the sleeve 2 communicates with a source of liquid glass 8. When opening and closing the valve 7, the glass fiber flows and liquid glass 8 in the tank 1. To regulate the amount of glass inside the sleeve 2 & on its inner part a platinum tube 9 is placed, direction & Lenna up through the valve 7. Valve 7 is connected to the regulator S through the screw of the pilot rod 11. The regulator of the U valve is connected to the sound indicator 12 of the depth, reacts to its signals and moves the valve 7 in accordance with them up or down the sleeve 2, allowing the glass melt to flow onto the sleeve 2. The strand fibers 13 are drawn through the openings 6 of the plate 5. A platinum rod 14 is in contact with the plate 5, which is connected to an electric current source that provides for an increase in the temperature of the plate. On the platinum rod 14, a measuring rod 15 is installed, providing an electrical current between them. The copper rod 15 is water cooled to reduce the temperature at the point of contact between the rods 14 and 15. The temperature of the plate 5 can also be controlled by induction heating. The temperature of the plate 5 is in the range of 20 50-2300 R. In the zone of exit of the glass cones from the die, the cooling medium is supplied in the form of a continuous stream 16 of gas at an angle of 4690 with means containing a gas nozzle 17. The gas nozzle 17 is located under the plate 5 with holes 6 at a distance of 2.6-51 cm. The base of the sleeve 2 has a ceramic support 18 for isolating from the plate 5 with holes 6. The reservoir I and the ceramic support 18 are surrounded by an insulating material 19 placed between the current-carrying rods 14 and 15 and source of liquid glass 8. Isolating ma The material 19 is an annular space 2O around the hub 2, in tank I with which the coil is heated i 21, designed to compensate for the heat loss associated with the thermal resistance of the insulating material. The coil of the heater 21 is connected to a thermocouple, with which the Monitoring of the amount of current flowing in it is carried out, in order to control the amount of heat generated by it to compensate for the loss. The second layer of insulating material 22 is placed on top and is spatially separated from the source of liquid glass 8, thereby creating an insulating gap 23. To provide coverage for individual glass fibers. a lubricant, for example, starch, to reduce friction between the cells by adjacent fibers under a gas nozzle of an installed oilcan 24. An example of the implementation of the proposed method. The standard sleeve without a tip used in this example is made of a flat sheet of an alloy plate (80% platinum, 20% for the sake of thickness O), 40 in. (1.0 mm). In a flat plastite, holes are drilled with QO, O 52 inches (1.32 mm), spread out with a hexagon with distances between the centers O, O 70 inches (11.78 cm). The rectangular portion of the sleeve, in which the holes are dispersed, is about 1.2 5 inches in width (3.125 cm) and approximately 2.85 inches in length (7.24 cm) with alternating rows of 17 and 18 holes. Each row contains approximately 46 holes. Type E glass is melted in a standard glass-making furnace to produce a molten glass bath, approximately 10 inches in depth (25.4 cm) with a temperature of approximately 2300 F (), which is what made the glass fibers using the plate described above. Plastium is supplied with a heater, and the plate temperature is maintained at about 2100 (1149С). Standard lubrication is carried out with the aid of a roller feeding it onto fibers that are wound at a speed of approximately 30,000 (min) (min. 914.4 m / min). In order to maintain the state in which the separation of the fibers takes place, from vertically arranged six nozzles 0 1.4 luys (0.61 cm) located in a row on one side of the plate with holes at a distance of approximately 5 inches (12.7 см cm), down, 59444 from it, the air flows, the flow of which is alpha upwards along the crest side of the part where the holes are located at an angle 15 from the vertical. Air is supplied under pressure, 5 values of which are in the range of 3-5 feet overpressure per square inch (from 0.21 to 0, 35 kg / cm I above atmospheric pressure). Successful stretching of the fibers under constant operating conditions while maintaining the separation of the filaments. In the process of use, there was some curvature of the plate with the spindles, and on it appear both concave, and flat areas, and the curvature of the plate does not improve the conditions for obtaining the plate. Claim 1. A method of making glass wool, in which fibers are drawn from a stream of molten glass mass that passes through flat fleecers, falls into the exit zone of the glass plates 76 from the spinnerer and surrounds the spray jet. It is due to the fact that, in order to improve the quality of the fibers, here the prevention of the filing of the die with molten glass mass, the cooling medium is constantly directed to the exit zone of the glass cone from the spinneret under the grades 46-90 from at least one stream of glass onus
