Compared with the prior art, the high-silica glass fiber and the preparation method thereof have the following advantages: the holmium oxide and the niobium pentoxide are introduced according to the optimized proportion, so that the high-temperature viscosity and the forming temperature of the glass are effectively reduced, the ductility of the glass material block is enhanced, and the high-strength glass fiber is obtained at relatively low melting temperature and wire drawing temperature.
The invention provides a fire-proof rolling door convenient for fire protection, and a using method thereof comprises the following steps:
the first embodiment is as follows: the initial state with rolling slats door main part 1, guided way I28 and guided way II 29 installation be fixed in on the wall body of building entrance to a cave under the initial condition, under ordinary state, drive roller 7 through control motor 9 and rotate and roll up and unreel rolling slats door main part 1, when motor 9 drives roller 7 and carries out clockwise rotation or anticlockwise rotation, lantern ring 13 drives each roller 21 and rotates, because motor 9 drives roller 7 pivoted speed comparatively slowly, when each roller 21 receives to rotate and to arbitrary one side slope, three roller 21 left and right sides receive gravity different, make sliding tray 18 to carry out sliding balance to the direction opposite with lantern ring 13 rotation direction, can regard as ordinary rolling slats door to use.
Example two: when a fire disaster occurs in a market or an exhibition hall, the motor 9 is controlled to rotate clockwise to put down the roller shutter door main body 1 after people in the market evacuate, the fire in a market or an exhibition hall is blocked and restrained, when fire fighters put out a fire to the fire, strike baffle 26 through the squirt and make support arm 25 drive rolling disc 17 and carry out clockwise rotation rapidly, rolling disc 17 extrudees each roller shaft 21 of 18 sliding discs under balanced state, make roller shaft 21 block in draw-in groove 27, the extrusion drives lantern ring 13 and rotates, lantern ring 13 drives sleeve pipe 11 and carries out clockwise movement, card axle 23 drops to the downside in following arc wall 12, the direction piece 32 leads to the card axle 23 that drops, make card axle 23 slide to the downside along lift spout II 31, make the folding opening that forms of compound steel fire prevention book curtain II 3 upper end whereabouts, the fire fighter of being convenient for puts out the conflagration through the opening part.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions are considered to be within the protective scope of the present invention.
