Glass fiber is a series of glass fiber semi-finished products made of various kinds of used glass through a complete set of glass fiber equipment. Its properties and uses are very wide. The fineness is 0.03mm-0.07mmg. The finished product is fine, silky, soft, like cotton, and tensile. Strong, color white, non-toxic, odorless, acid-resistant, alkali-resistant, corrosion-resistant, high-temperature resistant, and good insulation properties, are widely used in building materials, petroleum, chemical insulation materials, especially glass fiber reinforced plastics.
(I) Selection and cleaning of raw materials
1, the choice of raw materials A variety of waste glass, film diameter 3 cm but organic, mercury, brown and high temperature glass exception.
2. Cleaning of raw materials: Place the selected material in a cement pool or other container and put it into clean water. Mix and clean it with iron milling or a broom, clean the sediment on the glass surface, and then remove it. To clean the two pools again, be sure to wash away the sediment and then use it to remove the water from the bottom of the iron screen or other container with holes in the bottom.
3. If the surface of the glass is oily, wash it with warm water plus 4% caustic soda before use.
4, such as pure flat glass below 2 MM plus 2% of borax.
(II) Production of special equipment
1, a chemical fiber production equipment for a Taiwan 2, the other parts of the device: Motor: 0.5 -0.80KV. 80-1450 rpm. AC contactor: 80A or more. Third button switch: one

50 50 4.30 30-angle iron shaft, bearing, shaft base 205 only drum steel, pulley four 3, the prepared tools: a torch, gasoline, alcohol torches can be used, it is best to use kerosene torch safe and reliable. Drawing pliers: A 35mm long iron clip is self-made and the handle must be insulated. Insulation spoon: a 35mm long self-made, used to pick the glass and adjust the temperature within the bowl, the handle must be insulated. A hacksaw blade: 10 teeth and 20 teeth can be used under the wire.
The above drawing pliers and fishing rods were all made in an iron furnace. Electrode plate: 30 30CM several, yellow steel is suitable.
A pair of electric pliers, a voltage 500 V electric pen, a screwdriver: 6, 8, 10 each
(III) Installation and Usage of Machinery and Circuits: Instructions for Installing Electric Wires and Electrical Appliances
1, mechanical installation: According to the drawings size requirements of the installation of machinery, the rack height from the ground is 1.6 - 1.7 M is appropriate, the truss must be placed in the center of the centralized position, the truss must be flat, the distance to the concentration of rake For 38-40 cm, the distance from the drum to the ground is 40, the distance from the drum to the top of the crucible is 80, and the inclination of the wire is 25-30 degrees.
2. According to the drawings and equipment electricity description: (including voltage, power consumption, etc.), according to the description of the power consumption of each unit, select the cross-sectional area of ​​the wire, power. Connected to the various distribution electrical parts, the connector must be firmly connected.
3, the use of the circuit: From the meter you use the input cable 15A included in the knife is the power used by the motor, the motor and the single slot belt spinning machine is a type A live belt. The voltage of the spinning machine is 0.5 -0.8 KW. From the output of the 80A three-wire, access to the three-wire, direct access to the reverse switch, including the second line into the reverse switch, inverted Heshun input line seat, the other line is connected to the reverse switch "shun" open output line electrode plate. When the reverse switch is turned on and “invertedâ€, the 380 V whose output is changed to the second line is the high voltage. If the output is open, the output changes to the single-phase line with 220 V low voltage. If using AC contactor or compensator, use the same method to connect to the reverse switch, such as the use of 380 V low voltage electric insulation and temperature effect.
(4) Glass fiber production process and operation method:
1, glass fiber production process: raw materials - add water to clean - dry - into the crucible - torch light to preheat the fire - ignition heating 1100 - 1300 degrees - the glass melting temperature adjustment - drawing - pumping Silk - softening - on the silk - wire and wire - finished silk - packaging - finished - storage.
2, ignition (ignition)
Ignition and ignition are divided into three keys.
A, blowtorch ignition: The torch is used to burn the glass into a semi-liquid power supply, which uses petrol, kerosene, and sprinkler to help produce high temperatures.
B. Charcoal rod: Contact the electrode plate with a carbon rod to produce high-pressure molten glass. Use sodium oxide, copper oxide, and copper sulfate water to generate the voltage resistance. This procedure is complicated and difficult to grasp.
C, chemical raw materials: The preparation of drugs with several chemical raw materials, this is called the drug auto ignition with 220V voltage chemical composition is made of sodium hydride, sodium chloride glass powder, aluminum powder.
In the premise of igniting the fire, first warm up the torch. Refer to the instruction manual of the burner for details, fix the eyes of the scorpion, and remove the dust and scum sample on the surface of the stencil with a brush. Correct the size of your eyes, and then put the repaired file on the truss. Place it on the truss. Make sure it is leveled. Add glass afterwards. Be sure to add it to 1/4 of the file and fill it up. Do not exceed the two sides of the file. Size, do not add too much too much, to prevent the glass from flowing out, so that the preparation can be completed after the official ignition. It is best to ignite two people. If you are skilled, you can also use one person to operate. One took a preheated torch and ignited the stick. One controls the temperature switch (the button switch and the reverse switch). The person who blows the torch aligns the flame of the torch with the glass. The medium distance, baking glass, (note the ignition from left to right) until the glass melts and dissolves until it turns red. At this time, the electrode plate of the fire stick is leaned on the melted glass, and at the same time, the person controlling the temperature switch starts to play a low temperature (220 V). If you hit a high temperature prone to sparks, clutching the high temperature of 380 V, alternating with high temperature, then the fire stick slowly move to the left and right, continue to add glass. Keep hitting the heat. When the fire stick moves to a 1/3 degree of collapse, the temperature in the vortex rises rapidly. The fire stick must be in contact with the glass solution. Do not take it too high or press it down. Take it high. The contact is not likely to occur. With sparks, it is easy to feed the simmer continuously until the ignited electrode sticks the fire stick. This ends the process. Note: (1) The burner lamp must be warmed up before the point is entered.
In order to increase the service life of cockroaches, this must be done. At this time, due to the storage time and place, it may be damp or it may already be wet. If it is not first heated, it must be opened when it is ignited.
(2) Do not move the fire stick too fast or too slow. The temperature inside the bowl is too fast to catch up. The temperature is low and it is slow to cook it easily.
(3) If the inner glass bubble is found and the temperature is uneven. Use a spoon to pick it up. After releasing the air, use the hook to transfer the glass inside the bowl and mix it evenly.
3, drawing and drawing After the ignition or priming, the temperature of the glass in the bowl reaches 1100-1300 degrees, the glass will automatically flow out from under the eyes, if some eyes flow out of the glass, At this time, it is necessary to use a brushed wire drawing. When drawing, the posture is correct, from the outside to the pull, so that it is not easy to cut off the wire, do not touch the iron handle and the clip truss, so as to avoid electric shock, clip a few to stick, This will increase and speed up the speed of spinning. After all the wires are drawn, connect them by hand and then start the thread.
4, the silk on the roller before the first spray softener. Pull the pulled wire around the roller, be sure to press firmly the pressure head, push the roller by hand, after the wire is pressed firmly, open the motor, start the operation, enter the normal production, keep feeding, keep adjusting the temperature.
