Problems solved by technology

[0002] Ceramics, especially wear-resistant and / or corrosion-resistant ceramics, have excellent wear-resistant and / or corrosion-resistant properties, and are widely used in building materials, metallurgy, chemical industry, aerospace and other industrial fields, but the material has low toughness and strength. It cannot meet some engineering needs, and it is not easy to make large-scale products
[0003] FRP (or other fibers and their fabric-reinforced composite materials) is a widely used engineering material, which has the advantages of high strength, small specific gravity, and easy to make large-sized products, but has the disadvantages of poor corrosion resistance and wear resistance. short service life
Therefore, the application of FRP pipes is greatly restricted

Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment.

[0025] Such as figure 1 As shown, the ceramic and FRP composite pipes of the present invention are composed of three layers of ceramic inner layer 1, resin intermediate connection layer 2 and FRP outer layer 3 respectively. The ceramic inner layer is formed by splicing a plurality of ceramic blocks 4, and the splicing seams of the ceramic blocks are misplaced.

[0026] The specific preparation methods are respectively exemplified as follows:

[0027] Example 1. Using 10mm×10mm×4mm 92% alumina ceramic sheet as wear-resistant and corrosion-resistant ceramic material, alkali-free glass fiber as FRP reinforcement material, unsaturated polyester resin as FRP matrix, unsaturated polyester resin Ester resin is the material of the intermediate connection layer. Process the steel pipe into a core with a diameter of 150 mm and a length of 3.1 meters. Paste and fix the ceramic sheet on the ...

Abstract

This invention relates to a kind of ceramics, glass steel compound pipe which is composed of ceramic inner layer, middle connection layer and glass steel layer. The process method comprises the following steps: spraying resin middle connection layer on the inner ceramic pipe layer; then compounding glass steel outer layer. The compound pipe middle connection layer and the ceramic layer and the glass steel outer layer are tightly combined, which makes best use of the ceramic characteristics and the glass steel materials. The invention are most used in transmission of liquid medium with solid particles and the powders.

Description

technical field [0001] The invention relates to a technology of ceramics and glass-steel composite pipes, which belongs to the field of material composite technology, and is mainly suitable for the transmission of liquid media containing solid particles and powders. The glass fiber mentioned here generally refers to glass fibers or other fibers and their fabrics Reinforced composites. Background technique [0002] Ceramics, especially wear-resistant and / or corrosion-resistant ceramics, have excellent wear-resistant and / or corrosion-resistant properties, and are widely used in building materials, metallurgy, chemical industry, aerospace and other industrial fields, but the material has low toughness and strength. It cannot meet some engineering needs, and it is not easy to make large-scale products. [0003] FRP (or other fibers and their fabric-reinforced composite materials) is a widely used engineering material, which has the advantages of high strength, small specific gr...
