Description
【発明の詳細な説明】 〔技術分野〕 本発明はケイ酸カルシウム板、木片セメント板。[Detailed description of the invention] 〔Technical field〕 The present invention is a calcium silicate board and a wood cement board.
パルプ混入セメント板、石綿セメント板などのセメント
板の端部強度を劣化させなりためのセメント板の製造方
法に間中る。A method for manufacturing cement boards, such as pulp-containing cement boards and asbestos cement boards, is being developed to avoid deterioration of the edge strength of cement boards.
従来のセメント板の製造方法では湿式抄造機によって抄
造されたセメント生板をパレット上に数段に積み上げ積
載された状態で養生庫で養生し。In the conventional method of manufacturing cement boards, raw cement boards are made using a wet paper machine, stacked in several tiers on pallets, and then cured in a curing warehouse.
しかる後にこの養生されたセメント生板を自然乾燥や強
制乾燥をしてセメント板を得るのが一般的であった。し
かしながら、このようにパレット上に積載された状態で
養生されるためにセメント中の水分はセメント板の端部
付近で早く乾燥して蒸発しやすくなり中央付近との水分
差が生じやすくなるという問題があった。そのために、
セメント板の中央付近と端部では硬化速度が異なり内部
歪が発生し特に端部にセ論でクラツクが発生しやすくな
るという欠点があった。Thereafter, it was common to obtain a cement board by naturally drying or forced drying the cured green cement board. However, since the cement is cured while being loaded on a pallet, the moisture in the cement dries quickly near the edges of the cement board and evaporates easily, resulting in a moisture difference between the cement board and the center. was there. for that,
The curing speed differs between the center and the edges of the cement board, causing internal strain, which has the disadvantage that cracks are particularly likely to occur at the edges.
本発明は上述した背景技術に鑑みてなされたもので、そ
の目的とするところはセメント生板を養生後、含水用を
均一化して端部クラックの発生を防止することのできる
セメント板の製造方法にある。The present invention has been made in view of the above-mentioned background art, and its object is a method of manufacturing a cement board that can uniformize water content after curing the green cement board and prevent the occurrence of edge cracks. It is in.
以下、本発明の一実施例に係る第１図に基づＡて説明す
る。Hereinafter, an embodiment of the present invention will be explained based on FIG. 1.

するものである。Fresh cement boards 1 made by a Fourdrinier-type or circular-mesh type wet papermaking machine are piled up in several tiers on a pallet 2, and then heated and cured in a curing warehouse. The pallet 2 is disposed on the side end surface 3 of green cement boards loaded on the pallet 2, and the green boards are hardened to produce cement boards.
したがって、セメント生板１をバレット２上に積載養生

ことができる。Therefore, after the green cement board 1 is loaded on the bullet 2 and cured, water is sprayed on the side circumferential surface 4 of the green cement board 1. After drying, the moisture content becomes even between the center and the edges, and after drying, the moisture content becomes uniform, the curing speed of the cement becomes constant, and no internal strain occurs, which can prevent cracks.

る。As described above, the present invention provides a method for producing a cement board by loading and curing raw cement boards made by a wet papermaking machine, then spraying water on the side circumferential surface of the raw cement boards, and then drying and hardening them. Because of this, after the green cement board is cured, it can be dried and hardened in a state where the water content is homogenized, and cracks at the edges of the cement board can be prevented. Furthermore, since no complicated process is required, maintenance of the equipment is also simplified.
