Embodiment Construction

[0029] As shown in the figure, the expanded perlite heat-insulating shell of the present invention includes a heat-insulating shell body, the inner wall of the longitudinal section of the heat-insulating shell body has a concave-convex structure, and the surface of the inner wall is provided with a heat-reflecting film 3 。

[0030] The heat reflective film 3 Aluminum foil or silver white coating (can be aluminum powder coating).

[0031] The heat insulating shell body is composed of two or three arc-shaped split bodies butt joints, and the arc-shaped split body butt joint surfaces are correspondingly provided with sealing grooves 2 , sealing groove 2 A first sealing member is arranged in the enclosed space. Set sealing groove 2 And the first seal not only plays a good role in sealing and heat insulation, but also solves the problem of the seal breaking away from the seam after installation, and reduces the impact of damage to the heat insulation tube shell b...

Abstract

The expanded perlite heat-insulating shell with a heat-reflecting cavity and its production method relate to the improvement of the structure of the expanded perlite heat-insulated shell and its production method. The present invention aims at the above problems, and provides an expanded perlite heat-insulating shell with high efficiency and energy saving, good thermal insulation effect and simple structure and a production method thereof. The expanded perlite heat-insulating shell of the present invention includes a heat-insulating shell body, and its structural points are that the inner wall of the longitudinal section of the heat-insulating shell body has a concave-convex structure, and the surface of the inner wall is provided with a heat-reflecting film. The production method of the expanded perlite heat-insulating shell of the present invention comprises the following steps: 1) mixing the expanded perlite and an adhesive to form a mixture; 2) putting the mixture into a mold box of a molding machine, and pressing the heat-insulating shell with a concave-convex inner wall; 3) After demoulding, it is finished by drying.

Description

technical field [0001] The present invention relates to the improvement of expanded perlite heat insulating shell structure and its production method. Background technique [0002] Perlite is a kind of natural acidic glassy volcanic lava. Because its volume expands rapidly by 10 to 20 times under high temperature conditions of 1000 ℃ to 1300 ℃, it is collectively called expanded perlite. It is generally required that the expansion multiple is >10 to 16 times, and can be used as a filter, catalyst, molecular sieve, and carrier of rubber, chemical fertilizers, and pesticides; it is widely used in construction, metallurgy, petroleum, machinery, light industry, hydropower, casting, medicine, food, Departments of agriculture, forestry and horticulture. Common expanded perlite heat insulation shells use cement or sodium silicate as an adhesive, and after mixing, they are pressed into a circular shell consisting of 2 to 3 arc-shaped body parts through a mold. In order to reduc...
