A process and an apparatus for recycling resin scrap including a thermosetting resin paint film and a thermoplastic resin substrate as its major components, wherein the resin scrap is supplied into a passage of a cylinder, melted, and delivered by screw arrays from an upstream side to a downstream side of the passage of the cylinder, and hydrolyzed by a hydrolyzing agent while forming a highly packed region with a resistor. The resistor restricts the resin scrap to flow from the upstream side to the downstream side in a short period of time, and forms the highly packed region where a contact efficiency is enhanced between the resin scrap and the hydrolyzing agent.

Apparatus for recycling resin scrap

This invention relates to a method of manufacturing molded wooden products composed of a wooden body and a skin material. This method employs materials having long working life and enables simultaneous integral molding of the wooden body and the skin. The obtained molded wooden product has excellent characteristics.

Method of manufacturing a molded wooden product

A process for recycling a thermoplastic resin covered with a thermosetting-resin paint film includes the steps of decomposing the paint film by bringing the thermoplastic resin covered with the paint film into contact with a paint-film-decomposing agent in a molten state, and removing decomposed products, resulting from the paint film and the paint-film-decomposing agent, and the residual paint-film-decomposing agent by degassification to prepare a recycled resin. The paint-film-decomposing agent can be primary amines and/or secondary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less, or can be tertiary amines and/or quaternary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less to which water and/or alcohols is added.

Process for recycling resin covered with paint film

A process and an apparatus for recycling resin scrap including a thermosetting resin paint film and a thermoplastic resin substrate as its major components, wherein the resin scrap is supplied into a passage of a cylinder, melted, and delivered by delivering means from an upstream side to a downstream side of the passage of the cylinder, and hydrolyzed by a hydrolyzing agent while forming a highly packed region with a resistor. The resistor restricts the resin scrap to flow from the upstream side to the downstream side in a short period of time, and forms the highly packed region where a contact efficiency is enhanced between the resin scrap and the hydrolyzing agent.

Process for recycling resin scrap and apparatus therefor

Waste parts made of synthetic resin and having a hydrolyzable coating thereon are crushed into chips. The chips are supplied quantitatively to a hydrolyzer apparatus where they are continuously transported through the hydrolyzer with a screw while in contact with steam so as to hydrolyze the coating. The chips with the hydrolyzed coating are dried in a drying furnace and the dried chips are transported to a kneader wherein the hydrolyzed coating is kneaded into chips. The kneaded chips are cooled and then pelletized into pellets in a pelletizing apparatus.

Method for continuously recycling waste parts having a coating thereon

A binder, a water-repelling agent, and a mold release agent are added to wooden fibers obtained by splitting wood chips. This mixture is collected into a body having a particular shape without being formed into a mat. The collected body is compression molded under heat to make a molded wooden product.

A method of manufacturing a molded wooden product includes the steps of: preparing a ligneous molding material by adding a binder essentially consisting of a synthetic resin and the like to wood fibers; adjusting the weight of the molding material in a fibrous state or in a state of being aggregated into a predetermined configuration; directly supplying the molding material to a shaping mold; shaping the outer periphery of the molding material by moving the shaping mold toward the center in conformity with the final external shape of a molded product; and hot compression molding the molding material, thereby obtaining a molded wooden product of a predetermined configuration.

Method of manufacturing molded wooden product

A method is provided for producing an integral skin foam article made up of a skin, foam and core member. According to the method, an expanded layer which is of the same material as the skin is formed on the back of the skin prior to forming the article.

Method for forming a skin foam article

The foam slush molding apparatus of this invention comprises a mold and a hot air jacket, and an optional heat retaining hood. The hot air jacket and the optional heat retaining hood are provided along and a certain distance apart from the molding surface on which a resin is heated and fused. The molding surface and the jacket form a first hot air chamber for heating, and the jacket and the optional heat retaining hood form an optional second hot air chamber for heat retention. The apparatus permits uniform heating and foaming at an efficient molding cycle.

Foam slush molding apparatus

A molded wooden product comprised of wood fibers to which a binder containing a synthetic resin or the like has been added, characterized in that it has portions of varying thickness, preferably a deep-drawn portion and a thickened peripheral portion, the molded wooden product being of substantially uniform density throughout.

Molded wooden products

A method and apparatus for applying a synthetic resin layer to an outer surface of a metal part while the metal part is placed within a powdered mass of a thermally fusible synthetic resin. The metal part within the powdered mass is induction-heated to a temperature higher than a melting point and lower than a thermal decomposition point of the synthetic resin, in order to melt a portion of the powdered mass surrounding the heated metal part, and thereby permit the molten portion of the powdered mass to be deposited as the synthetic resin layer on the outer surface of the heated metal part. To facilitate the placement of the metal part in the powdered mass, air may be blown into the powdered mass to keep the mass in a fluid state.

Method and apparatus for coating metal part with synthetic resin

A slush mold for molding film moldings such as surface coverings of interior finishing parts of automotive vehicles. The slush mold comprises a mold body having a molding surface of a predetermined shape formed in the inner surface thereof, a skirt capable of being detachably joined to the mold body so as to cover the marginal portion of the inner surface of the mold body other than the molding surface so that a resin film molding is formed only over the molding surface, and guide members for guiding the skirt so that the skirt is joined correctly to the mold body. Thus, the molding material is distributed only over the molding surface, and thereby the yield rate of film moldings is improved and the work in the subsequent process is facilitated.

Slush mold

High-density polyisocyanurate resins having improved rigidity, heat resistance and/or impact resistance can be obtained by reacting a polyisocyanate with a polymer polyol derived from a polyol having a molecular weight of at least 4500, and optionally a crosslinker, in the presence of trimerization catalyst, using isocyanate index of 200-5000.

Polyisocyanurate resin and process for making the same

A flexible foamed product with skin, characterized in that on the surface of the foamed product there is formed a skin composed of the reaction product of a linear urethane polymer, a polyol or an urethane prepolymer with an OH-terminal group compatible with the linear urethane polymer, and a blocked isocyanate; and the process for manufacturing such a product.
