摘要： PURPOSE:To obtain a sealant which can prevent the evolution of mildew for a long time by adding a small amount of three specific mildewcides to a silicone sealant. CONSTITUTION:This sealant is obtained by adding p-chloro-m-xylenol (A), bis(2- pyridylthio-1-oxide) zinc salt (B) and 2-(4-thiazolyl)benzimidazol (C) to a silicone sealant. The amount of the active ingredients of the three compounds to be added to the sealant is preferably 0.1-3%. The proportion (by weight) of the compounds A, B and C is 1-8:1-8:1-8, preferably 2-5:1:1. By the addition of a small amount of the three mildewcides, the sealant can be prevented from being detriorated by a number of mildews, and hence it can be effectively used as a sealant for the interior and exterior of buildings and tile joints.

摘要： PURPOSE:To manufacture inexpensively, simply and in a short time by making blocking hard to occur, by a method wherein a plasterboard is brought into contact with a curtain film formed under a state wherein a coating liquid is streamed down by inclining in the advancing direction of the plasterboard rather an a vertical line and inclined forward in the advancing direction of the plasterboard rather than the vertical line. CONSTITUTION:Application of a coating liquid such as vinylidene chloride resin is performed by a curtain flow coating. At this time, the coating liquid 2a is streamed down through a stream down port 71 by a curtain film 13 of the coating liquid so that the coating liquid 2a is inclined forward in an advancing direction of a plasterboard 1 rather than a vertical line. It is preferable that this angle theta of inclination is established at 10 deg. or lower. A moistureproof coating such as vinylydene chloride resin is formed at 60-70gr/m on base paper of the plasterboard 1 like this. Generation of blocking is prevented by formation of the moistureproof film of this kind.

摘要： PURPOSE:To raise the moisture-proofing effect of a gypsum board by a method in which the surface of a gypsum board is covered uniformly with a resin film only by a regulated amount per unit area to form a moisture-impermeable layer. CONSTITUTION:While supplying a gypsum board 1 of a Stoeckigt size of 340sec. or more continuously at a rate of 100-180 m/min, a synthetic resin emulsion 2a containing 50-60wt% vinylidene chloride copolymer particles of an average grain size of 1-13pm, consisting of 85-95 pts.wt. vinylidene chloride and 5-15 pts.wt. (meth)acrylate, is applied to the gypsum board l to coat it with a thickness of 0.1-0.5mm of film from a curtain flow coater 7. The emulsion 2a coat on the board 1 is dried at 120-200 deg.C for 1.5-2.0min to form the resin film of 60-70g/m2 on the board 1. The board 1 is placed on pallets and cooled to form a moisture-proof gypsum board 10.

摘要： PURPOSE:To enable a press curing time to be shortened, and obtain sufficient adhesion by providing a great number of small holes on the adhesive surface of a lumber in a method of adhering a lumber to a gypsum board wherein a preservation treated and monthproof-finished lumber is pressed to the gypsum board via an adhesive layer. CONSTITUTION:Upon adhering a preservative treated and monthproof-finished lumber 1 to a gypsum board 4 via an adhesive layer 3 in application of pressure, a great number of small holes 2 are provided on the adhesive surface of the lumber 1. The adhesive comes into the small holes 2, and thus the surface area of the adhesive layer 3 becomes large, accordingly, the drying can be done promptly and the curing time can also be shortened. And, the adhesive comes into the small holes, and thus the adhesive layer engages to the lumber, thereby increasing adhesive forces therein.

摘要： PURPOSE:To surely prevent a slip accident by forming on the upper surface of a wood surface plate of a panel a resin waterproof first coating layer forming on its upper surface a resin waterproof final coating layer and coating grains, adhering to the upper of the first coating layer, with the final coating layer. CONSTITUTION:A plywood surface plate 2 applies to its upper surface a resin waterproof first coating layer 3 arranging on its upper a particle 5 of sandy grain or the like adhering. Next on the first coating layer 3, a resin waterproof final coating layer 4 is applied, thereafter the plate 2 is dried by a hot air drying furnace, forming a building panel 1.

摘要： PURPOSE:To improve a fire protection performance by burying a fire protecting material in a recessed groove provided on the surface material of a joint and a surface material above this recessed groove in the structure of the joint against which a facing material butts with a space disposed. CONSTITUTION:In the structure of a joint C where facing materials 10, 10 butt against each other, fire protecting materials 50, 30 are buried in a recessed groove 21 provided on the surface material 20 of the joint and the joint C above the recessed groove 21. The facing material 10 is composed of fire protecting material such as asbestos cement slate, asbestos cement calcium silicate board, ALC board. The fire protecting materials 30, 50 are composed of foaming asbestos member, rock wool felt, slate, ceramic fiber felt, fire proof putty, fire proof cement. Thereby, since the thickness of the fire protecting materials 30, 50 can be increased, fire protecting performance can be improved.
