There are provided a method of recovering a base paper for gypsum board for continuously and efficiently recovering a base paper for gypsum board from a waste material of gypsum board including a gypsum core and the base paper for gypsum board adhering thereto. The method of recovering a base paper for gypsum board includes steps of breaking the waste material of gypsum board, separating a gypsum component and a paper piece of the base paper for gypsum board from the broken waste material of gypsum board, and washing the separated paper piece with water using a rotary drum-type washing device so as to eliminate a gypsum component adhering to the paper piece.

High odor eliminating property is provided to a building material for interiors by compounding a hydrazide compound. Additionally, the odor eliminating property of the building material for interiors is improved and hygroscopicity and size stability at the time of use are provided by adding and compounding an organic carbide, an inorganic hygroscopic material, and a water repellent. Also, an interior structure in which these building materials for interiors are employed is provided.

A strip-pack manufacturing apparatus is adapted to attach an end part of an article to a strip. The strip-pack manufacturing apparatus includes a holding part, first and second rollers, a stopper member and an adjusting part. The holding part is configured and arranged to hold and transport the article to a predetermined attaching position. The first and second rollers are arranged in a receiving position at which the holding part receives the article. The first and second rollers are configured and arranged to rotate while sandwiching the end part of the article therebetween. The stopper member is configured and arranged to control the position of the end part of the article that has been drawn by rotation of the first and second rollers to stop at a predetermined position. The adjusting part is configured and arranged to adjust a distance between rotation axes of the first and second rollers.

A strip-pack manufacturing apparatus for attaching an end part (Z) of a bag (X) to a strip comprises holding means for holding the bag (X) and transporting the same to a predetermined attaching position; a pair of rollers (52a, 52b); a stopper (84); and adjusting means. The pair of rollers (52a, 52b) are provided to a receiving position at which the holding means receives the bag, the rollers rotating while sandwiching the end part (Z) of the bag (X). The stopper (84) controls the position of the end part (Z) of the bag (X) to stop at a predetermined position, the end part (Z) having been drawn by the rotation of the pair of rollers (52a, 52b). The adjusting means causes a supporting member (78) for supporting one of the rollers (52a, 52b) to pivot around an axis is that parallel to a rotation axis of the roller (52b), thereby adjusting the distance between the axes of the rollers (52a, 52b).

A strip-pack manufacturing apparatus is adapted to manufacture a strip-pack in which at least first and second articles are attached to a strip. The strip-pack manufacturing apparatus includes an attachment part and an orientation control part. The attachment part is configured and arranged to attach an end portion of each of the first and second articles to the strip. The orientation control part is disposed downstream of the attachment part, and configured and arranged to control the orientation of the first article attached to the strip prior to the second article while the attachment part attaches the second article to the strip.
摘要:
A water repellent gypsum composition comprising a gypsum, and a paraffin emulsion prepared by emulsifying (a) paraffin hydrocarbon having a melting point of 40.degree.-80.degree. C and (b) an oxidized paraffin having an acid value of 10-70 at a ratio of from 97:3 to 50:50 by weight, respectively, in the presence of a water soluble alkali compound. Optionally, a polymer emulsion or solution may be added.
