A preparation method of glass flakes with different sizes and uniform inner wall thickness

Abstract

The invention discloses a method for preparing different sizes of glass flakes with inner walls of uniform thickness, belonging to the technical field of ocean anticorrosive paints. After being shaped, high temperature hollow glass beads are spherized by a blower system so that the inner wall of the hollow glass bead is homogenized, finally, the hollow glass beads with the inner walls of uniform thickness are rolled and crushed by a steel roller, so as to obtain different sizes of glass flakes with inner walls of uniform thickness. In the process of preparing the hollow glass beads through a solution bubbling method, the formed hollow glass beads are flat due to self gravity, if the flat hollow glass beads are rolled by the steel roller directly, the obtained glass flakes do not have uniform thickness and affect the usage later, therefore, the step of spherizing the hollow glass beads by the blower system is carried out before the step of rolling by the steel roller. The blower system does not require great changes of the preparation system, but can be used for improving all the physical parameters of the prepared glass flakes, so that glass flakes have wider application range.

Description

technical field [0001] The invention relates to the technical field of marine anticorrosion coatings, in particular to a method for preparing glass flakes with different sizes and uniform inner wall thickness. Background technique [0002] The 21st century is the ocean century, and the development and rise of the ocean economy will inevitably lead to the development of a large number of ocean equipment and infrastructure. Due to the particularity of the marine environment, higher special requirements are put forward for the performance of engineering equipment. [0003] The corrosion of reinforced concrete facilities in the marine environment is very serious, and the corrosion in the spray splash area is generally 0.3-0.5 mm per year, and the maximum can reach 1 mm. Marine corrosion has become a common problem faced by the whole world. In my country, marine steel structure corrosion has been paid more attention, while marine concrete anti-corrosion coatings are in its infan...

Problems solved by technology

However, in the actual process of preparing glass flakes, hollow glass beads are generally prepared first, and there are methods such as bubbling. The process will cause the glass beads to become oval, and then make the inner wall uneven, resulting in uneven thickness of the scales, and the thickness of the scales prepared by the above method is not easy to control
