Description
【発明の詳細な説明】 この発明は水硬性石綿セメント板の加圧法に関する。[Detailed description of the invention] This invention relates to a method for pressurizing hydraulic asbestos cement boards.
従来、水硬性セメント板に対してたとえば表面凹凸模様
を付与する場合には凹凸が付与された上型または下型の
抑圧により金型の凹凸を転移せしめてなされていたが、
この加圧の目的には、水硬性セメント板に含水されてい
る水分のうちセメントの水和反応に供されない余分の水
分を圧出せしめ、次工程の硬化に要する時間の短縮も含
まれていた。Conventionally, for example, when giving a surface unevenness pattern to a hydraulic cement board, it was done by transferring the unevenness of the mold by suppressing the upper or lower mold to which the unevenness was applied.
The purpose of this pressurization was to press out the excess water contained in the hydraulic cement board that was not used in the hydration reaction of the cement, thereby shortening the time required for the next hardening process. .
そこで従来は圧出された余分の水分を吸水する目的でた
とえばフエルトの如き微多孔質の吸水性マットを使用し
ていたが吸水性マットが平坦な面であるために上型、下
型の解圧と同時に一旦吸水された余分の水分が再び加圧
された水硬性石綿セメント板に移動し、上記目的が十分
に達せられない状況であった。Conventionally, a microporous water absorbent mat such as felt was used to absorb the excess water that was squeezed out, but since the water absorbent mat has a flat surface, the upper and lower molds cannot be used. At the same time as pressure was applied, excess moisture that had been absorbed once moved to the hydraulic asbestos cement board that was pressurized again, making it impossible to fully achieve the above objective.
本発明は以上の事実に鑑みてなされたもので、圧出され
た余分の水分が水硬性セメント板に再帰するのを防いで
加圧できる水硬性石綿セメント板の加圧法に関し、次工
程の省エネルギー、又は時間短縮に有効なものである。The present invention has been made in view of the above facts, and relates to a pressurizing method for hydraulic asbestos cement boards that can prevent excess water that has been squeezed out from returning to the hydraulic cement board and save energy in the next process. , or is effective in reducing time.
以下、本発明を具体的に説明する。The present invention will be specifically explained below.
図において１は上型、２は下型、３はプレス機の上盤、
４はプレス機の下盤で、上型１は上盤３に、下型２は下
盤４に取付けられている。In the figure, 1 is the upper mold, 2 is the lower mold, 3 is the upper plate of the press,
Reference numeral 4 denotes a lower plate of the press machine, in which the upper die 1 is attached to the upper plate 3 and the lower die 2 is attached to the lower plate 4.
そしてこの下型２の上にはフエルト５が載せられており
、さらにこのフエルト５の上に被加圧体の水硬性石綿セ
メント板６が載せられ、上型１と下型２の圧締によって
水硬性セメント板が加圧される。A felt 5 is placed on the lower mold 2, and a hydraulic asbestos cement board 6, which is a pressurized body, is placed on top of the felt 5. The hydraulic cement board is pressurized.
この場合、フエルト５は表面に多数の排水溝７が縦横に
形成せられている。In this case, the felt 5 has a large number of drain grooves 7 formed vertically and horizontally on its surface.
フエルト５は厚み方向に弾性を有しているから、加圧さ
れると排水溝７はつぶれて厚みが均等される。Since the felt 5 has elasticity in the thickness direction, when pressurized, the drainage groove 7 is collapsed and the thickness is made uniform.
そして上型１、下型２間が解圧されると原形に復帰し排
水溝７が再生する。When the pressure between the upper mold 1 and the lower mold 2 is released, the drain groove 7 is restored to its original shape.
しかるに解圧と同時に加圧時に一旦吸水した石綿セメン
ト板の余分の水分はこの排水溝７に浸出し排水されるか
ら石綿セメント板に再帰する水分は減少するのである。However, at the same time as the pressure is released, the excess water in the asbestos cement board that has absorbed water during pressurization is leached into the drainage groove 7 and drained, so that the amount of water that returns to the asbestos cement board is reduced.
なお、吸水性マットさしては、フエルトの他にスポンジ
でもよく特に制限はない。Note that the water-absorbent mat may be a sponge in addition to felt and is not particularly limited.
以上の如く本発明によれば、被加圧体の石綿セメント板
に含有された余分の水分を加圧時に圧出せしめて吸水マ
ットに吸水せしめ、吸水された水分は解圧時に原形に復
帰した吸水マットの排水溝に浸出するから石綿セメント
板に再帰する水分は減少し、次工程の省力に有益なので
ある。As described above, according to the present invention, the excess water contained in the asbestos cement board of the pressurized body is forced out during pressurization and absorbed by the water absorption mat, and the absorbed water returns to its original shape when the pressure is released. The amount of water that leaches into the mat drainage channels and returns to the asbestos-cement board is reduced, which is beneficial for saving labor in the next process.
