Problems solved by technology

The main disadvantage of this type of technology is that the product after casting has macroscopic defects such as air bubbles and pores, which are prone to leakage. Moreover, during the heat release process of the resin, it will deform and form cavities, resulting in hardness, flexural strength and other indicators. None meet the requirements

Abstract

The invention provides a novel high-performance hydrofluoric acid-resistance artificial functional composite plate and a preparation method thereof. The plate is mainly made of barite aggregate, resin and a serial of modified agents. According to the preparation method, the finished plate can be formed after a serial of processes of barite packing graduation, special resin and the serial of modified agents adding, mixing and stirring, organic combination reaction, plate blank forming, high-temperature and high-pressure reaction, high-frequency vibration, cure reaction (80-120 DEG C), thickness determining, polishing, bridge cutting, detection and the like. The composite plate has special anti-corrosion performance, excellent mechanical performance and durability, and is superior in product conveying, installation, maintenance and the like.

Description

technical field [0001] The invention relates to a hydrofluoric acid-resistant artificial composite board and a preparation method thereof. The product is suitable for various anticorrosion projects, especially for acid-resistant anticorrosion projects of hydrofluoric acid or mixed acids, and belongs to the field of anticorrosion materials. Background technique [0002] Industrial anti-corrosion materials are widely used in petroleum and chemical industries, mainly for oil and gas pipeline anti-corrosion, chemical plant equipment, floor and urban sewage treatment, etc. With the rapid development of my country's industry, the demand for anti-corrosion materials has increased sharply, especially high-performance and low-cost anti-corrosion materials, whose market size is second only to building materials. At the same time, as an industrial anti-corrosion material, how to have a long service life of 10 years or even more than 15 years, and it is suitable for a very harsh corrosi...
