Description

Detailed Description of the Invention This invention uses calcium carbonate powder as the main raw material, which is stably supplied at a relatively low cost. do,
Shock resistance in non-porous board, [111 strength custom made, etc.
It has been designed to provide effective encouragement.

Therefore, the previous inorganic board (e.g., Tsunagi Sukan, senont, plaster, etc.) had poor molding properties, and the light board material FW, II was provided by Tasaku. In addition, the pure inorganic base plate is not considered to have sufficient impact resistance, bending strength, etc., and it cannot be cut, drilled, or nailed. The special characteristics of the sieve are extremely poor.

Compared to this, add 1+/4 finger adhesive in the inorganic powder.
, person, 'j! Of course, in the case of inorganic plates provided with J-type hair, since the bone structure 1... is completely covered with the glue, it is inevitable that there will be a large amount of resin used. It was treated with acid, and this functioned as a hard resin and cedar board rather than as an inorganic board.

The present invention 4 This inorganic plate l15L11 method has been devised in view of the disadvantages of the conventional tilted sound plate.
Two types of aggregates are made of fine calcium carbonate powder, and a resin film such as electrified vinyl is attached to the surface of the aggregate to connect the bones. The gap other than the part of the film that will be subjected to foaming is 1lji
I, phrenology! T, 1% 4J eliminates the room for the intervention of unnecessary (V-1 pilgrimage materials), and makes it possible to promise the same functional effect as when V-1 is placed on an almost pure non-1 geometric board, and everyone itself The aim is to make the music lighter, the music is custom-made, and the impact resistance is improved.

The foamed inorganic cell according to the present invention! In detail, an example of a manufacturing method targeting 11 is shown. 2 (1%

The non-absorbent ib turf was obtained by heating and foaming in the Q++) chamber.

In addition, as for the demolition that can be discharged in the meantime, alcohol, acetone, benzene, trichlene, formic acid, tetrahydrofuran, etc. are selected as appropriate according to the first samurai of the control index number 7 used in 1st history. In addition to being used as a blowing agent, azobisisobutylene (funitrile, soda carbonate, freon, propane, butane, or pentane, etc.) are also used in sorting 1. It is I.
