A method for soldering or welding components in a series production wherein: a fixing seam which connects the components (1, 2) is produced by melting a connecting material (3), which is supplied as an additional material or is formed by a base material of the components (1, 2), along a joint formed by the components (1, 2); and a volume-forming layer of connecting material is deposited onto the fixing seam by melting, or the fixing seam produced by means of the connecting material supplied as an additional material is re-melted.

The invention belongs to the technical field of high polymers and relates to a high-strength high-toughness low-odor polypropylene composition and a preparation method and usage thereof. The high-strength high-toughness low-odor polypropylene composition comprises the following components in parts by weight: 50 to 80 parts of polypropylene, 2 to 9 parts of compatilizer, 0 to 10 parts of thermoplastic elastomer, 0.1 to 0.5 part of antioxidant, 0.2 to 1 part of deodorant and 15 to 35 parts of glass fiber. The composition selects low-odor homopolymerized and copolymerized polypropylene matrix resins, selects a low-odor compatilizer and a reactive deodorant simultaneously, and is simple in production process flow, high in production efficiency, continuous in production process and stable in product quality. The composition maintains the advantages of the polypropylene matrix, and additionally has the capacity of enhancing the strength and the toughness are improved, and reducing the odor is reduced, so that the composition has the comprehensive performance of high strength, high toughness and low odor; and moreover, the requirement on the automotive trim comfort can be well met, and the composition has a good application prospect.

Disclosed is an industrial microwave ultrasonic reactor. The inner wall of the reactor is provided with a liner; a microwave generation device is composed of microwave units distributed over the outer sidewall of the reactor in a spaced manner, or of a microwave pipe provided outside the reactor and microwave units distributed over the microwave pipe in a spaced manner. One end of the microwave pipe is in communication with the bottom of the reactor via a connecting pipe I and the other end is in communication with the top of the reactor via a return pipe. A shield is provided outside the microwave generation device to space the microwave units apart from the outer space, with a heat removal device being provided outside the shield. The microwave generation device is composed of ultrasonic pulse units provided along the outer sidewall of the reactor in a spaced manner; there are 10 - 30 sets of ultrasonic pulse units provided from top to bottom, each set having 10 - 50 members and being distributed along the circumferential direction of the reactor, and a stirring shaft of a stirring device is fixed below a stirring motor and extends into the reactor. The present reactor can shorten the time for chemical leaching, improve the purity of a product extracted and increase operation efficiency.
