[Industrial Application Field] The present invention relates to a method for producing glass fibers used for various purposes such as heat insulating materials, plastic reinforcing materials, concrete reinforcing materials, and the like. [Prior art] In the past, a new glass raw material was prepared, heated and melted, and the molten glass was threaded into a fiber shape (no literature available.) [Problems to be solved by the invention] However, Currently, most of the raw materials for glass fibers are imported, which has the drawback of being expensive due to the instability of resources.Additionally, heating and melting the raw materials requires a huge amount of thermal energy, making running costs extremely expensive. It was hot. An object of the present invention is to significantly reduce both raw material costs and energy costs, thereby making it possible to provide extremely inexpensive products. [Means for solving the problem] The characteristic means of the present invention is to heat and melt waste mainly consisting of sewage sludge in a state in which the composition has been adjusted by adding a calcium source and a silica source, and to cool the obtained molten slag. The purpose is to create a product with a CaO/SiO 2 ratio of 0.6 to 1.1 by stringing it into a fiber before solidifying, and its effects are as follows. [Operation] When waste mainly consisting of sewage sludge is heated and melted by adding a calcium source and a silica source to obtain a product with CaO/SiO 2 of 0.6 to 1.1, and the molten slag is processed into strings. It was confirmed through experiments that long fibers with sufficient strength as glass fibers and excellent heat resistance and alkali resistance could be obtained. Since waste is used as the main raw material, the raw material cost is extremely low, and with the spread of sewage treatment, large amounts of sewage sludge can be stably obtained, so there is no need to worry about securing raw materials. Furthermore, melting treatment of waste is effective in terms of detoxification and weight loss, and is currently becoming widespread.According to the present invention, the by-products of waste treatment can be effectively utilized by using thermal energy for the treatment. It will be recovered and used as glass fiber, and judging from this standpoint, the raw material cost and energy cost in glass fiber production can be considered almost unnecessary, making it possible to keep the product price extremely low. [Effects of the Invention] As a result, it has become possible to provide glass fibers at a low price and advantageously in terms of waste treatment, resource saving, and energy saving. In addition, it is possible to obtain glass fibers with excellent heat resistance that can withstand high temperatures of, for example, 1000°C or more.
Compared to conventional glass fibers , which had a temperature of about 500℃ or less, it is now possible to significantly improve heat resistance. As a result, it has become possible to significantly improve alkali resistance.
It has become possible to develop new uses for glass fiber. [Example] Next, an example will be shown. (Example 1) An appropriate calcium source or silica source is added to the dried cake of sewage sludge or the incinerated ash of sewage sludge, or to the mixture thereof with other appropriate waste such as municipal waste incinerated ash, After adjusting the ingredients, the raw material with the adjusted ingredients is heated and melted in an appropriate type of furnace to produce molten slag with a softening point of about 900 to 1300°C. Before cooling and solidifying the molten slag,
The fiber is drawn into a fiber shape using an appropriate device at a temperature of ~1300°C to produce a glass fiber with a CaO/SiO 2 ratio of 0.6 to 1.1. In addition, the composition of the said slag, the composition of the said glass fiber, and the composition of the conventional glass fiber are illustrated below.

スフアイバーを得た。[Table] (Example 2) Sewage sludge was adjusted in composition by adding CaO, heated and melted in a furnace that forms a high-temperature hearth with coke, and the molten slag was passed through a platinum nozzle while maintaining the temperature at 1180°C. Then, threading is performed at a speed of 600m/min.
Glass fibers with an average diameter of 15 μ and an average tensile strength of 83 Kg/mm 2 were obtained. (Example 3) The composition of sewage sludge is adjusted by adding crushed stone, and the sewage sludge is heated and melted in a furnace that forms a high-temperature hearth with coke.The molten slag is heated at a temperature of 1,210°C and is passed through a platinum nozzle for 600 m. String processing is performed at a speed of /min.
Glass fibers with an average diameter of 13 μ and an average tensile strength of 100 Kg/mm 2 were obtained.
