This relates to a method of manufacturing an inorganic substrate characterized by applying vertical vibration through a band 2, and its purpose is to uniformly distribute the sedimented slurry in the length direction and width direction, thereby increasing the thickness. An object of the present invention is to provide a method for manufacturing an inorganic substrate that can obtain an inorganic substrate with high specific gravity accuracy.
従来、長網式抄造機における材料の均一供給については
フローボックスの長さを大きくとることによる均−化又
はアジテータ−による攪拌分散が行なわれている。Conventionally, in order to uniformly supply materials in a fourdrinier paper machine, equalization by increasing the length of the flow box or stirring and dispersion using an agitator has been carried out.
これらの方法によると、材料流れ方向の両サイドの壁の
抵抗により中心部に材料の多い即ち中高の基板になる傾
向があった。According to these methods, due to the resistance of the walls on both sides in the direction of material flow, there was a tendency for the substrate to have a large amount of material in the center, that is, to have a medium height.
又、濾過が終了した時点よりロールあるいはバーによる
強制的に埼−化を行なうこともあるが、この場合は材料
の流れが少なく、材料の多い所はバンクが出来、出来た
基板表面にうろこ状のフローマークやクラックが出来る
欠点がある。In addition, when filtration is complete, a roll or bar may be used to forcibly form the material, but in this case, the flow of the material is small and banks are formed where there is a lot of material, leaving scales on the surface of the resulting substrate. It has the disadvantage of forming flow marks and cracks.

に分離される。However, cement, gypsum, calcium silicate, calcium aluminate monosulfate hydrate (hereinafter referred to as MS)
When the slurry 4 is supplied onto the papermaking zone 2 in the bottom shape of an inorganic substrate such as calcium aluminate trisulfate hydrate (hereinafter referred to as TSH), the sedimentary slurry 1, supernatant water 5, and papermaking zone 2 are formed. Passed filtered water 6

この状態で加振されることにより沈降スラリー１が振動
状態になり、凸部から凹部へ材料が移行し、且つフェル
トのような比較的抵抗の大きい濾材ではかえって濾水性
が良くなる。By being vibrated in this state, the sedimentary slurry 1 is brought into a vibrating state, and the material is transferred from the convex portions to the concave portions, and the filtering properties are actually improved with a filter medium having relatively high resistance such as felt.
なお振動を上方より加える例も考えられるが、上方より
加振すると材料の一部のみ゛・振動の分配が不充分であ
る。It is also possible to apply vibration from above, but if vibration is applied from above, only a part of the material will be affected, and the distribution of the vibration will be insufficient.

基板を得ることができるものである。In the present invention, vertical vibration is applied from the back side of the settled slurry during filtration through a paper band made of net, felt, etc., so that the settled slurry can be uniformly distributed and divided in the length direction and width direction. It is possible to obtain an inorganic substrate with good thickness, specific gravity, and precision.
