technical field

The invention relates to the field of flexible glass coil processing, in particular to a chemical thinning process and a device for producing a flexible glass coil by a continuous method.

Background technique

Traditional glass is brittle material, they exist in the form of plate or block, and the flexibility is very poor, but once its thickness falls below a certain value, the bendability and softness of glass show.

Flexible glass refers to glass with a thickness of less than or equal to 0.12mm. Flexible glass belongs to the category of ultra-thin glass, and its preparation method is often improved on the basis of the preparation method of ultra-thin glass.

At present, the preparation methods of flexible glass mainly include physical methods and chemical thinning methods.

However, it is quite difficult to prepare glass below 0.1mm by physical method.

However, the current chemical thinning method is to use pieces of glass for chemical etching, which is very inefficient.

The purpose of the present invention is to solve the shortcoming of low production efficiency in the production of flexible glass at the present stage, and propose a chemical thinning process for producing flexible glass coils by a continuous method.

In order to achieve the above object, the present invention provides a chemical thinning process for producing a flexible glass coil by a continuous method, and the specific technical scheme is as follows:

The flexible glass coil wound on the semi-finished drum can be thinned to any required thickness through chemical thinning grooves and chemical etching. The obtained flexible glass coil with preset thickness is wound on the finished drum. Realize continuous production; among them, the speed of the semi-finished product drum and the finished product drum can be adjusted; after drying, the finished flexible glass with the required thickness is obtained.

For example, 0.12mm thick glass can be chemically thinned to 0.03mm. The thickness of the thinning can be controlled by speed, temperature, and potion concentration. Specifically, if the speed is fast, the thinning will be slow; if the temperature is high, the thinning will be fast; if the concentration of the liquid medicine is high, the thinning will be fast.

Preferably, the flexible glass coil on the semi-finished drum is etched through the chemical thinning groove by pulling from one side of the chemical thinning groove to the finished barrel on the opposite side of the chemical thinning groove.

Another object of the present invention is to provide a chemical thinning groove with a chemical thinning function in a chemical thinning process.

The present invention provides a chemical thinning device, comprising a chemical thinning tank, a semi-finished drum located on one side of the chemical thinning tank, and a finished drum located on the other side of the chemical thinning tank, so The semi-finished product drum is used for winding the semi-finished product of the flexible glass coil, and the finished product drum is used for winding the finished flexible glass coil. The settling baffle at the bottom of the thin tank, the limit roller shaft located in the middle of the chemical thinning tank, and the corrosion-resistant heating rod located at the bottom of the chemical thinning tank, make the flexible glass coil on the semi-finished drum from the chemical thinning tank. On the opposite side of the chemical thinning groove, continuous production is achieved by pulling the etched through the chemical thinning groove to the finished cartridge on the opposite side of the chemical thinning groove.

Preferably, both the semi-finished product drum and the finished product drum are provided with speed regulating motors.

Preferably, the chemical thinning device further comprises a filter tank and a circulating water pump, and the circulating water pump is connected to the chemical thinning tank through the filter tank.

Preferably, the chemical thinning tank is made of acid and alkali resistant plastic.

The chemical thinning device provided by the present invention can also be used for cleaning the glass coil wound on the drum. That is, the same set of devices can also be used for cleaning.
