Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は無機質性＋１の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for producing inorganic +1.
従来、セメント配合物より建材を製造することが広く行
われ、その製造方法として丸網抄造法、長網抄造法を始
め押出成形法、連続鋳込法など種々の製造法が知られて
いる。BACKGROUND ART Conventionally, building materials have been widely manufactured from cement mixtures, and various manufacturing methods are known, including round net papermaking, fourdrinier papermaking, extrusion molding, and continuous casting.
しかしながら、上記製造法の内、丸網抄造法は抄き上げ
られた薄い挿脱を幾層も積層していく製造法であるから
基本的に板状体の製法にしか適さず、さらに積層製品で
あるから層間剥離か生し易い問題がある。However, among the above manufacturing methods, the round netting method is a manufacturing method in which thin inserts and inserts are laminated in many layers, so it is basically suitable only for manufacturing plate-shaped objects, and furthermore, it is suitable for manufacturing laminated products. Therefore, there is a problem that delamination is likely to occur.
また長網抄造法は上記した欠点はなく厚手の製品も成形
可能であるが、製品賦形は移送・脱水・＼ルト上で行わ
れるので製品断面形状賦形のためのｌ：１−ル等を複雑
に配置する必要があり、装置が複雑となり、また回転駆
動部分の糺持管理も厄介となる問題があった。In addition, the Fourdrinier papermaking method does not have the above-mentioned drawbacks and can form thick products, but since the product shaping is carried out by transferring, dehydrating, and ＼rutting, it is possible to shape the cross-sectional shape of the product. It is necessary to arrange the parts in a complicated manner, making the device complicated, and also making it difficult to manage the adhesiveness of the rotary drive part.
押出成形法はかなり複雑な断面形状の製品であっても連
続成形可能であるが、原料配合に押出助剤の添加が必要
となり、成形性改良のためのスラリーの管理が欠かせず
、しかもこのような管理を行っていてもなお成形不良が
生しることかあるといった困難性を有する。The extrusion molding method allows continuous molding even for products with quite complex cross-sectional shapes, but it requires the addition of extrusion aids to the raw material mixture, and slurry management is essential to improve moldability. Even if such management is carried out, molding defects may still occur.
連続鋳込法は生産がハノチシステＪ、となり効率が悪い
問題があった。The continuous casting method had the problem of low efficiency because production was difficult.
この発明は上記問題点に鑑み、製品の断面形状賦形は押
出成形法と同様な利点を有すると同時に原料の調整等に
関する管理等は殆ど不要であり極めて容易に複雑な断面
形状をなす無機質製品を製造し得る方法を提供すること
を目的としてなされたものである。In view of the above-mentioned problems, this invention provides inorganic products that have the same advantages as the extrusion molding method in terms of the cross-sectional shape of the product, and also requires almost no management regarding the adjustment of raw materials and can extremely easily form a complex cross-sectional shape. The purpose of this work was to provide a method for producing .

水成形することを特徴とするものである。That is, the method for producing inorganic Kengetsu of this invention includes cement,
A slurry consisting of siliceous raw materials, calcareous raw materials, lightweight aggregates, reinforcing fibers, and the required amount of water is fed into a tapered raw material supply pipe whose cross-sectional shape gradually approaches the product shape and whose discharge l] is shaped like the product. The slurry is discharged while applying vibration to the tapered raw material supply pipe, and the discharged product is dehydrated and molded while being transferred on a transfer heald equipped with a dehydrating Naction box. .
〔作用〕
この発明において製品の断面形状の賦形は、原料供給口
は広く、ここから断面形状が次第にテパ状に挟まり吐出
口か目的製品の断面形状とされた原料供給管により行う
。[Operation] In the present invention, shaping of the cross-sectional shape of the product is carried out using a raw material supply pipe having a wide raw material supply port, from which the cross-sectional shape gradually tapers, and the discharge port has the cross-sectional shape of the target product.
そして、この原料供給管に振動を与えつつセメント配合
物を流動供給する。Then, the cement mixture is supplied in a flowing manner while applying vibration to this raw material supply pipe.
従って、セメント配合物よりなる原料は、振動するテー

料供給管内面に沿って製品断面形状に整えられていく。Therefore, the raw material made of the cement mixture flows in the vibrating tapered raw material supply pipe in a straight line, and at this time, the vibration destroys the air bubbles contained inside and flows along the inner surface of the raw material supply pipe. The cross-sectional shape of the product is then adjusted.
そして、製品形状に賦形されて１１１出された成形品は
脱水用ザクシコンボックスをｒｉｔｆｉえた移送ヘルＩ

、養生に適した水分含有量に調整されるのである。Then, the molded product that was shaped into the product shape and put out 111 was transferred to a transporter I which was equipped with a dehydrating Zakushikon box.
-, and is dehydrated while being transferred by the transfer heald, and the moisture content is adjusted to be suitable for curing.
次にこの発明の詳細な説明する。 Next, this invention will be explained in detail.

The outlet 3A is supplied to a tapered raw material supply pipe 3 whose shape has a predetermined product cross-sectional shape, and the tapered raw material supply pipe 3
The material was caused to flow while being vibrated by the vibration device 4.

The material was received by a felt transfer heald 6 equipped with a felt roller, dehydrated and finally shaped by a shaping roll 7, and then transferred to a pallet (not shown) for a curing process.

また、製品の任意部分を切断し気泡の含有状態を調査し
たところ、内部気泡は全く発見されなかった。Furthermore, when an arbitrary part of the product was cut to investigate the presence of air bubbles, no internal air bubbles were found.

The product cross-sectional shape of the compound is shaped by the vibrated tapered raw material supply pipe, so to speak, by gravity flow, so there is no need to use an extrusion aid for cement compound as in the extrusion method. There is no need for equipment, so it is easy to mold products with complex cross-sectional shapes.Moreover, since internal air bubbles are completely destroyed by vibration, molded products with dense structures can be molded, and there is no need for excess moisture. Since the tube is dehydrated during transportation in the transfer heald, it maintains its shape until curing, which has various effects.
