Electrostatic dry powder spraying ceramic powder composite material

Abstract

The invention relates to an electrostatic dry powder spraying ceramic powder composite material, which comprises the combination of the following base materials in part by mass: 45 to 60 parts of network former, 2 to 17 parts of network forming and fusing agent, 8 to 13 parts of network modifier and fusing agent, 15 to 20 parts of flux and 5 to 7 parts of nucleating agent, wherein the network former is silicon dioxide; the network forming and fusing agent is diboron trioxide; the network modifier and the fusing agent are alumina, magnesia, calcium oxide, sodium fluoroaluminate and zinc oxide; the flux is sodium oxide, potassium oxide and lithium oxide; and the nucleating agent is titanium dioxide, zirconia and phosphorus pentoxide. A steel structure sprayed by the material in the open air and under atmospheric pollution environment for a long period can effectively prevent rust corrosion; and moreover, the service life of a highway guardrail plate, an upright post and the like can reach over 30 years.

Description

technical field [0001] The invention relates to a kind of electrostatic dry powder spraying which is used in a wide range of projects, especially iron and steel structures which have been exposed to the open air and air pollution for a long time, and which can effectively prevent rust and corrosion, especially for expressway guardrails and columns, etc., with a service life of more than 30 years Porcelain powder composite material. Background technique [0002] The anti-corrosion of steel is a worldwide issue. Due to the development of electrostatic dry powder spraying porcelain powder materials, it is aimed at the construction of my country's expressway grand projects, which require tens of millions of tons of guardrails, pipe columns and other metal structures. Because the traditional process of galvanizing, aluminum plating, plastic spraying, etc. has been widely used as surface anti-corrosion materials, pickling, alkali washing and other treatments have brought pollution ...

[0002] The anti-corrosion of steel is a worldwide issue. Due to the development of electrostatic dry powder spraying porcelain powder materials, it is aimed at the construction of my country's expressway grand projects, which require tens of millions of tons of guardrails, pipe columns and other metal structures. Because the traditional process of galvanizing, aluminum plating, plastic spraying, etc. has been widely used as surface anti-corrosion materials, pickling, alkali washing and other treatments have brought pollution to the environment and the atmosphere. With a large number of installations and utilization, time continues , light catalysis, aging and decomposition also form follow-up pollution
