【発明の詳細な説明】
本発明は、硝子繊維屑の処理方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating glass fiber waste.
硝子長繊維は溶融した硝子をブツシングに穿設
した多数の小孔から流出せしめ、この溶融硝子を
引伸することによつて製造される。この硝子繊維
にバインダー（集束剤）を附与して集束すること
により硝子繊維束が得られ、硝子繊維束は各種用
途に供せられる。 Long glass fibers are produced by flowing molten glass through a number of small holes drilled in a bushing and drawing the molten glass. By adding a binder (a sizing agent) to the glass fibers and bundling them, a glass fiber bundle is obtained, and the glass fiber bundles can be used for various purposes.
硝子繊維束の製造、或は二次加工の段階におい
て多量の屑が発生する。近時省資源、省エネルギ
ーの観点から硝子繊維束屑の再生利用について各
種提案がなされており、その一つとして硝子繊維
原料（バツチ原料）としての利用が試みられてい
る。 A large amount of waste is generated during the manufacturing or secondary processing of glass fiber bundles. Recently, various proposals have been made regarding the recycling of glass fiber bundle waste from the viewpoint of resource and energy conservation, and one of them is the use as a raw material for glass fiber (batch raw material).
板硝子、硝子容器等の製造工程において発生し
た硝子屑は、所定の大きさに粉砕しカレツトとし
てそのまま硝子原料として使用することができ
る。しかしながら、硝子繊維屑を硝子原料として
そのまま、或は切断して硝子溶融窯に投入する
と、硝子繊維に附着しているバインダーが炭化し
て炭化微粒が生成し、この炭素微粒が溶融硝子中
に混入し、着色の原因となり或は泡発生の原因と
なる等の難点があつた。 Glass waste generated in the manufacturing process of glass plates, glass containers, etc. can be crushed into a predetermined size and used as cullet as it is as a raw material for glass. However, when glass fiber waste is used as a raw material for glass and fed into a glass melting kiln either as it is or after being cut, the binder attached to the glass fibers is carbonized and carbonized fine particles are generated, and these carbon fine particles are mixed into the molten glass. However, there were drawbacks such as causing coloring or foaming.
このため硝子繊維屑を硝子原料として使用する
場合、硝子繊維屑を予め処理しバインダーを除去
することも試みられているが、工業的に好適な方
法は知られていなかつた。 For this reason, when glass fiber waste is used as a raw material for glass, attempts have been made to treat the glass fiber waste in advance to remove the binder, but no industrially suitable method has been known.
例えば、硝子繊維屑を水洗することによりバイ
ンダーを除去する方法が提案されているが、この
方法（水洗法という）は、硝子繊維屑の脱水、乾
燥工程を必要とするだけでなく、廃水の処理工程
も必要となる。しかも二次加工の段階で発生した
屑に附着しているバインダーは水洗法では殆んど
除去することができない。 For example, a method has been proposed in which the binder is removed by washing glass fiber waste with water, but this method (referred to as the water washing method) not only requires dehydration and drying steps of the glass fiber waste, but also requires wastewater treatment. Processes are also required. Furthermore, the binder attached to the waste generated during the secondary processing stage cannot be removed by washing with water.
又、硝子繊維屑を加熱し、バインダーを燃焼除
去する事も試みられているが、加熱処理を充分高
温であり、且つ酸素を多量に含有する雰囲気中で
行う必要があり、又、処理に比較的長時間を要す
る難点がある。この条件を満たさない場合はバイ
ンダーが炭化してしまい、燃焼除去が困難とな
る。 Also, attempts have been made to heat the glass fiber waste and burn off the binder, but the heat treatment needs to be carried out at a sufficiently high temperature and in an atmosphere containing a large amount of oxygen, and compared to the treatment, it is difficult to remove the binder. The problem is that it takes a long time. If this condition is not met, the binder will carbonize, making it difficult to remove by combustion.
本発明者は、かかる難点を解決する為、検討を

し、本発明として提案したものである。 In order to solve these difficulties, the present inventors have conducted repeated studies and have found that glass fiber waste is pulverized, the resulting pulverized product is mixed with a powdered glass raw material, and the mixture is heated to a temperature of 600°C or higher containing oxygen. It has been discovered that suitable results can be obtained by bringing a high temperature gas into contact with the glass fiber waste to combust the binder attached to the glass fiber waste, and the present invention has been proposed.

となく除去できる。 When using the method of the present invention, carbonization does not occur even when glass fiber waste is heated at a relatively low temperature in an atmosphere with a low oxygen content, and the binder can be removed in a short time. For example, 0 2 to 7
The binder can be removed without carbonizing by heating at 600°C for several minutes in an atmosphere containing 10 vol%.

る。 Such a pulverized material is mixed with a raw material for powdered glass, and the mixture is brought into contact with a high-temperature gas containing oxygen at a temperature of 600° C. or higher to burn off and remove the binder adhering to the pulverized material. The amount of oxygen that should be contained in the high temperature gas is 7 vol% or more, preferably
It is appropriate that the amount is 10 vol% or more, and the temperature of the gas is preferably 600°C or more, preferably 650°C or more. Note that heating is suitably carried out in a state in which the mixture of the pulverized material and powdered glass raw material is brought into contact with a high-temperature gas while being made to flow. As such a heating method, a fluidized bed can be used, but preferable results can be obtained by injecting the mixture of the pulverized material and powdered glass raw material into a high-temperature gas while being suspended in the gas. You can get it. Alternatively, a rotary kiln may be used, and the mixture may be fluidized and heated by the rotation of the rotary kiln.

除去することができる。 When using the method of the present invention, there is no need to heat the glass fibers at a high temperature for a long time in an atmosphere with a high oxygen content to prevent carbonization of the binder, and the glass fibers can be heated at a relatively low temperature in an atmosphere with a low oxygen content. Even when heated, the binder can be completely removed in a short time.
