Problems solved by technology

Therefore, the ceramic wave-transparent components that are accidentally polluted must be derusted, otherwise they will be unusable and scrapped, causing serious economic losses
[0003] Existing rust removers are mostly used for metal products or organic products in the construction, machinery, metallurgy, textile, mineral resources or electronic device industries. Phosphoric acid, sulfuric acid and other non-volatile strong corrosive substances or organic macromolecular substances with high carbon residues, and there is no rust removal device suitable for wave-transparent material components, which cannot meet the conditions of comprehensive performance of ceramic wave-transparent material devices without damage. Harmless derusting requirements

Embodiment 1

[0029] refer to figure 1 and figure 2 , weigh 2 parts of hydrochloric acid, 4 parts of oxalic acid, and 40 parts of deionized water, stir and mix evenly, and put them into the liquid storage tank for later use; Spray the pipeline and each ball valve, and start the circulation pump to spray and clean the rust removal liquid of the ceramic components. Stop the machine after spraying for 36 hours, observe with the naked eye that the rust stains on the ceramic components dissolve and disappear, take out the ceramic components, and clean the spray tank and delivery pipeline with clean deionized water, and then put the ceramic components into the clean spray tank again And placed directly below the nozzle. Then, connect the cleaning pipeline to the liquid storage tank containing clean deionized water smoothly, and start the circulation pump to implement deionized water to rinse and replace the adsorbed acid in the components. During the replacement process, clean water was repla...

Abstract

The invention relates to a method for removing rust stains on a porous quartz ceramic wave-transmitting material. According to the method, a solution containing hydrochloric acid and oxalic acid serves as a rust remover, a rust removal device serves as a hardware support, and rust stains are removed through the technological processes of leaching dissolution, replacement and drying. The combination of hydrochloric acid and oxalic acid is adopted as a rust removal component, the strong acidity of hydrochloric acid, the strong reducibility of oxalic acid and the complexing property on iron ions are utilized respectively, the rust removal rate can be greatly increased, the rust removal time is shortened, and the rust removal rate is increased; the components of the derusting liquid are easy to decompose and volatilize after being heated, and no redundant material residue is generated after the derusting treatment of the ceramic part; the rust removal device is simple in structure, easy and convenient to operate, stable in process, high in pollutant removal efficiency and high in construction economy; the method is suitable for acid-resistant porous ceramic materials of different fiber types and fabric structures, and the process adaptability is high.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to. Background technique [0002] Due to its high temperature resistance, high strength, low expansion, low dielectric and many other performance advantages, ceramic wave-transparent materials are increasingly used in electrical functional components of various combat weapon systems. In particular, fabric-reinforced ceramic materials have many internal pores and are easy to absorb foreign substances, and the general structure of wave-transparent components is relatively complex, the production process is long, and there are many processes. Most of the process equipment is made of carbon steel and the hardness of the ceramic material itself is relatively high. As a result, iron stains or rust stains will inevitably appear in the ceramic wave-transparent components during the production and preparation processes such as billet making or processing. However, rust will ser...
