摘要： A method for producing a formed product of deproteinized natural rubber latex capable of reducing a content of an allergen in a natural rubber latex material to a level sufficient to keep the latex from being harmful to the human body without decreasing yields of the product and deteriorating formability of the latex. In the method, cleaning removal of a non-rubber content is carried out after each of protein decomposition, prevulcanization and forming. An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02% by weight or alcohol-water mixed liquid containing alcohol in an amount of 5 to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.

摘要： A hollow extruding die for extruding a hollow section of a zinc-containing aluminum alloy is provided. The die is protected from cracks and has an extended life, without requiring any substantial structural changes to the die. In the die mandrel of the die a mandrel is connected by bridges with an outer cylindrical member. The bridges have a tapered projection facing toward the mandrel. A 3 mm thick coating composed of a nickel alloy is bonded on the surface of the projection by padding the welding material. Instead of coating the bridges, a covering can be attached to the surface of the bridges. To receive the covering, an engaging groove extends from the root of the mandrel and along the surface of the bridges to the outer cylindrical member of the die mandrel. The covering is composed of the same steel material as that of the die or of the nickel alloy. The covering has a through hole for receiving the mandrel formed on the base. At the opposite sides of the through hole, the covering has projecting portions that are disposed parallel to the mandrel and the covering is tapered along the bridges.
