Building Materials Encyclopedia: Treatment and Utilization of Glass Fiber Waste Wire

The system consists of cleaning, crushing, cleaning, drying and transportation.
Scrap removal

Waste paper tube, wire, nuts and other debris, open wire, metal detector metal.

Scrap broken

Crusher inlet needs to be set to control the amount of feed to the roller, the product is 5mm short fibers and powder, more fine-grained: secondary crushing after drying, plus air separation device.

Scrap washing

After rinsing with water, the sizing agent adhered to the fibers is rinsed off, and the water of the waste silk is washed. The treated water of the sewage treatment station can be used with as little or no tap water as possible. The washed water is returned to the sewage station for processing. The washed fiber is initially separated from the water by a sand separator.

Waste wire drying

The dryer is sent to the dryer for continuous drying. The hoist has a variable frequency speed control function, and the feed rate affects the moisture content of the dried product. Dryer energy, natural gas, steam drying, but also use the heat of the stove drying oven. Fiber content after drying is less than 1%. According to the production needs, it can be put into the tank or ton bag for standby, or it can be pneumatically conveyed to the use bin.

The use of waste wire

1. Application in continuous fiber production

Note the following points:

1 The kiln head is set to feed on both sides, and as far as possible, the amount of feeding on both sides is the same.

2 It should be as dry as possible. The moisture content should not exceed 1%. It is even more necessary for non-alkaline ponds and kilns.

3 The alkali-free waste wire can be fine-grained, while the caustic is the opposite, as thick as possible.

4 Supplement the volatile components B and F in the glass fiber chemical composition.

2. Application in glass wool production

1 Because the alkali 5# glass fiber component is the same as the alkali alkali glass wool component, the alkali alkali waste fiber can be directly used for the production of alkali alkali glass wool.

2 alkali-free glass fiber composition and alkali-free glass wool composition contrast:

Comparison instructions

It can be seen from the comparison that there is only a slight difference between Si, Al, B, R2O, and other components except CaO and MgO. In production, the raw materials used for the introduction of CaO and MgO in the original formulation are mainly supplemented, and the remaining components can be adjusted to meet the production needs.

3. Application in embossed glass production

The use of waste wire to produce embossed glass has been introduced for a long time. Its main method is based on the composition characteristics of medium and non-alkali waste wire, and an ingredient composition similar to that of embossed glass is configured in accordance with the medium and alkali-free waste wire volume 2:1. The following table:

The quartz sand and soda ash are used to modify the low SiO2, R2O, and high CaO, MgO, Al2O3 and other components to form a composition recipe that meets production needs. The approximate formula is as follows:

In production, care should be taken to properly control the annealing temperature (about 570°C) and molding temperature.

4. Application in glass mosaic production

The use of medium and alkali-free waste silk for the production of glass mosaic has been for many years. Due to the different colors of glass mosaics, there are certain differences in the composition of the glass mosaics. According to the composition requirements of different colors, the use of alkali or alkali-free waste wires is selected. However, in order to meet the requirements of product color and thermal stability, chemical stability, mechanical strength, etc., further adjustments must be made to the ingredients, and silica, limestone, potash feldspar, soda ash, soda ash, fluorite and other minerals should be properly added. Raw materials and different colorants.

5. Production of Ceramic Glaze Using Glass Fiber Scrap

The basic components of the glass fiber are all required for the ceramic glaze, and especially the non-alkali fiber contains 7% B2O3, which is a common component for the glaze. It can reduce the melting temperature of the glaze, prevent the glaze layer from cracking and improve the glaze. Surface hardness, gloss and chemical resistance. Due to the high price of boron raw materials, the proportion of glaze costs is high. Making full use of useful components of waste silk can greatly reduce the production cost of glaze.

Conclusion

1. The use of waste filaments listed above is an example that has been tested in production practice. It is technically feasible and economically significant.

2. With alkali-free waste wire as an example, the raw material cost of waste wire is about 1,050 yuan/ton, and boron raw material accounts for about 600 yuan/ton. At present, the price of waste silk take-out is only one hundred tons or so. It can be seen that the use of waste wire has great economic value. Making full use of the useful components of waste wire can bring considerable economic benefits.

3. According to the composition of waste silk, actively explore the use of channels, the use of waste wire, can bring about certain economic benefits and reduce pollution and pollution for the society. Can kill two birds with one stone. Qualified companies, based on the composition of waste silk, are actively exploring ways and channels to use them, creating more wealth for businesses and society. To add a clear water and blue sky to our human living environment.
