摘要： PROBLEM TO BE SOLVED: To provide a tubular body coating method capable of excellently coating the inside surface of a socket while discharging power paint with small discharge quantity.SOLUTION: A nozzle 32 and a tubular body 1 arranged on the axis line L of the tubular body 1 are reciprocated relatively along the axis line L direction while rotating the tubular body 1 around the axis line L. The electrically charged powder paint is discharged from the tip part of the nozzle 32 to coat the inside surface of a heated socket 12. Two discharge openings 321 mutually extended in parallel are arranged in the tip part of the nozzle 32 to be symmetric to the axis line L. The powder paint discharged in the axis line L direction from two discharge openings 321 is spread with a prescribed angle range θ in a fan-like form in a plane surface in parallel to the extended direction of the respective two discharge openings 321. As a result, the density of the discharged powder paint is made high and thereby, the inner surface of the socket 12 is excellently coated while discharging the powder paint with the small discharge quantity.

摘要： PROBLEM TO BE SOLVED: To leave no odor in a pipe.
SOLUTION: This pipe protective cap 10 mounted to the pipe end of the pipe (p) with solvent-based coating applied to the pipe inner surface, includes an adsorbent containing part 20 facing the internal space of the pipe (p) mounted to the pipe (p). The adsorbent containing part 20 has a function of adsorbing a volatile component of a coating material used for the solvent-based coating. Since the adsorbent containing part 20 has the function of adsorbing the volatile component of the coating material used for the solvent-based coating, odor in the pipe can be eliminated without enlarging the holes of the pipe protecting cap 10 or increasing the number of holes. If the odor can be eliminated, the holes of the cap can be made small, the number of the holes can be reduced, or the holes themselves can be eliminated. A function of suppressing the intrusion of foreign matter into the pipe can thereby be exhibited.

摘要： PROBLEM TO BE SOLVED: To obtain the seal coat material capable of being coated on a cement- hardened substrate such as the mortar lining of a cast steel pipe to prevent the elusion of an alkaline substance, etc. SOLUTION: This penetrable waterproof composition comprises (A) a vinylic polymer containing 2-20wt.% of an acid monomer and (B) the mixture of an epoxy group-containing organoalkoxysilane and an organoalkoxysilane in a (A)/(B) ratio of 0.1-10. The organo alkoxysilane in the composition penetrates into a substrate to reinforce the substrate and form a water-repelling layer, and the vinylic polymer forms a resin layer for protecting the water-repelling layer. Since the acid groups especially react with the epoxy groups to improve the adhesive strength between both the layers, higher water resistance than those by conventional techniques is formed, and the function is maintained over a long period to solve problems.
