Organic glass sealing operation box for chemically polishing glass

Abstract

The invention provides an organic glass sealing operation box for chemically polishing glass. The sealing operation box consists of a front vertical plate, a right vertical side plate, a left vertical side plate, a back vertical plate, a bottom plate and a top plate, and is characterized in that the left upper corner and the right upper corner of the front vertical plate are provided with glove interfaces respectively; an operation box door is arranged at the middle lower position of the front vertical plate, and is provided with an operation box door cover comprising an external thread and a sealing ring; water grooves are formed inside and outside boxes of the left and right vertical side plates; each water groove is provided with a solution injection hole, a solution drainage hole, an air inlet and an air outlet; and alkaline solutions are injected into the water grooves inside and outside the box, so that hermetic isolation of toxic gases is realized. The organic glass sealing operation box is reasonable in overall design, is low in manufacturing cost, and has the characteristics of high transparency and corrosion resistance; and the personal safety of experiment personnel is ensured effectively, purification of toxic gases is realized, and pollution on the surrounding environment is prevented.

Description

technical field [0001] The invention relates to an organic glass sealed operation box suitable for glass chemical polishing, which belongs to the field of chemical experiment operation boxes. Background technique [0002] Chemical polishing is a common method of glass polishing. In the process of chemical polishing of glass, such as the preparation of polishing solution, glass polishing, polishing solution treatment, etc., volatile toxic gases, as well as strong corrosive and oxidizing strong acid solutions, among which the toxic gases are mainly hydrogen fluoride , and the strong acid solution is mainly concentrated sulfuric acid. Hydrofluoric acid is a colorless transparent fuming liquid, which is an aqueous solution of hydrogen fluoride gas. It is easy to volatilize in an open container, has strong corrosiveness and toxicity, and can strongly corrode metal, glass and silicon-containing objects. If 1.5 g Hydrofluoric acid can cause immediate death. Concentrated sulfuric...

AI Technical Summary

Problems solved by technology

There are many types of sealed operation boxes on the market. For example, the vacuum environment operation box for nanofluid preparation with patent No. 200810202356.8 is made of steel and tempered glass. The vacuum glove box 02219258.1 is made of stainless steel, does not have gas purification treatment, and will be corroded by hydrofluoric acid at the same time; for example, the portable anoxic operation box with patent number 200610039509.2 lacks a gas purification system; such as patent The water and oxygen fractionation and purification vacuum glove box No. 200810095796.8 is mostly made of stainless steel. Although it has a purification system, the objects of purification are water and oxygen; these sealed operation boxes are not suitable for the experimental operation of glass chemical polishing
