摘要： PROBLEM TO BE SOLVED: To reduce the cure shrinkage of a lining material for pipe interior coating by compounding an unsatd. polyester resin, an unsatd. polymerizable monomer, a peroxide initiator, a (meth)acryloylated styrene macromonomer, and specific flat particles. SOLUTION: Component A is prepd. by compounding 100 pts.wt. unsatd. polyester resin having a number average mol.wt. of about 1,000-50,000, a hydroxyl value of 5-100mgKOH/g, an acid value of 5-30mgKOH/g, and an unsaturation equivalent of 100-1,000 with 5-200 pts.wt. unsatd. polymerizable monomer (e.g. acrylic acid or styrene), 1-40 pts.wt. (meth)acryloylated styrene macromonomer having a number average mol.wt. of about 1,000-10,000, 10-500 pts.wt. flat particles having a length of 80μm or lower (e.g. silica or talc), about 0.5-10 pts.wt. cure catalyst, and a solvent. Component B is prepd. by the same formulation except that it does not contain the catalyst and contains 0.1-20 pts.wt. peroxide initiator. A lining material for pipe interior coating is obtd. by mixing components A and B just before being used.

摘要： PURPOSE: To provide a carrying device for powder, wherein the capacity capable of following the size of necessary discharge quantity can be freely variable in pneumatically transporting a fine particle coating to be used for an iron pipe, etc., and stable in carrying and easy in maintenance. CONSTITUTION: A wind box 13 is formed via a porous plate 11 on the bottom part of a closed tank 1, and an injector 2 for carrying a fine particle coating P is opening/closing freely fitted to the lower part side surface of the tank. A pressure adjusting valve 3 is opening/closing freely fitted to the top surface of the tank. Consequently, a fine particle in the closed tank can be pressured while flowing, thereby allowing the free selection of the rate of discharge capacity reinforcement for the injector 2 by pressure adjustment. A level can be sharply improved from in view of the versatility, simplicity, stability, and maintenance.

摘要： PURPOSE: To improve the corrosion resistance of an iron pipe and the like for channel or gas pipeline to be buried. CONSTITUTION: A copolymer water dispersion in which 5-50wt.% of a conjugated diolefin having 4-6 carbon atoms is necessarily copolymerized with 3-10wt.% of at least one of ethylenic unsaturated carboxylic acids is used as a main component by use of a reactive emulsifier having a polymerizing ethylenic unsaturated group to prepare a coating material, and the coating material is applied to the inner and outer surfaces of an iron pipe covered with a Zn primer as a sealer by frame coating. Thus, even when the surface of the iron pipe makes contact with the moisture in the soil, the emulsifier is never eluted from the coating film, and fast projecting function can be kept long. Since the coating material itself is highly corrosion-resistant, and the moisture penetration to a metal layer as substrate can be arrested, corrosion by ionization of the metal is also prevented. Further, properties such as stability, impact resistance, and white rust prevention as coating material are also remarkably more excellent than in a conventional technique.

摘要： PURPOSE:To prevent degradation of water quality by covering the surface of the rubber of a water-sealing rubber ring for use in the joints of a variety of city water pipes with a flexible resin coating harm less to human, at least over an area where the surface of the rubber could make contact with water passing through a pipe. CONSTITUTION:In a joint where a spigot 2 is fitted into the socket 1 of a cast iron pipe with a bolt and nut 4 tightening a retaining ring 3 and a socket flange together, a rubber ring 5A is interposed between the portion of the spigot 2 pressed by the end of the retaining ring 3 and the retaining ring 3 inside the socket 1, thus sealing water passing through a pipe so that it does not leak outside. In this case, the surface of rubber used in the rubber ring 5A is covered with a flexible coating 6A of a resin harmless to human, at least over an area where the surface could make contact with the water passing through the pipe. The coating 6A is preferably made of an olefine resin such as fluororesins and polyamide resins, so that even if trace amounts of toxic substances are added to the rubber, the coating prevents the toxic substances from dissolving into the water.

摘要： PURPOSE:To obtain a method for subjecting water-swellable rubber to surface treatment without especially limiting a water-swellable resin to be used and readily reducing consumption of potassium permanganate in extracting water. CONSTITUTION:In a method for surface treatment, unvulcanized rubber (EPDM) is mixed with water-swellable rubber (e.g. crosslinked polyacrylate-based resin), molded, then vulcanized to produce water-swellable rubber, which is oxidized at least on the surface. The oxidation can be carried out by immersing the water-swellable rubber in an aqueous solution of a peroxide, chlorine or a chlorine compound (sodium hypochlorite). Consequently, consumption of potassium permanganate based on dissolution examination shown by JIS K6,353 can be readily reduced to

摘要： PURPOSE:To uniformly coat the inner surface of a bent pipe having a large curvature by packing a mixture of different powdery materials in the bent pipe so that the reaction propagation velocity is made low at the inner periphery side and high at the outer periphery side, and always keeping the reaction interface horizontal along with the rotation of the bent pipe. CONSTITUTION:The mixture of a strong reducing agent and the powder of a metal oxide is packed in the hollow part of the metallic bent pipe 1 and pressed, the upper part of the packing material is heated to initiate a reaction, and a thick ceramic layer is formed on the inner surface of the bent pipe 1 while controlling the attitude. The thermites having different reaction propagation velocities are packed, for example, in three layers A, B, and C so that the reaction propagation velocity is made low at the inner periphery side and high at the outer periphery side. The rotation of the bent pipe is simultaneously controlled so that the reaction interface is always kept horizontal when the interface descends in the bent pipe 1. The inner surface of the bent pipe 1 having a large diameter and wherein the distance between the outer periphery and inner periphery is great can be coated.

摘要： PROBLEM TO BE SOLVED: To prevent breakage of any of air valve constituent members such as a guide member when water within the air valve receives a sudden pressure change.SOLUTION: A guide member 4 of an air valve is divided into two, that is, an upper guide 4a and a lower guide 4b, while a safety valve 18 is installed in a floating valve element 6. By dividing the guide member 4, mutual force of constraint in a vertical direction is severed, thereby, when the inner pressure of the guide member 4 receives a sudden pressure change, the breakage of the guide member 4 can be prevented. Furthermore, when the inner pressure exceeds a predetermined value, the safety valve 18 is activated so as to escape the inner pressure, thereby any of the constituent members of the air valve such as a guide member 4, floating valve element 6, float valve body 7 and the like can be prevented from being damaged due to the sudden change of the inner pressure.
