Problems solved by technology

[0002] In recent years, liquid crystal materials used in liquid crystal display devices are stored in metal packaging containers, but the inner walls of metal packaging containers are easily corroded by the materials contained inside, which affects the quality of materials; as time goes by, metal packaging Elements of the matrix material of the container itself will precipitate and produce new chemical changes, which is not conducive to long-term storage and greatly shortens the service life of the storage container

Embodiment 1

[0027] First, prepare a 100L acid-resistant and corrosion-resistant open container; calculate the volume required for each raw material according to the volume ratio (19L of nitric acid; 5L of sulfonic acid; 3L of diphosphoric acid; 5L of monobutyl ether; 1L of zeolite; 62L of water; other adsorption Water 62L of the calculated corresponding volume is poured in the container; 19L of nitric acid is slowly added in required water, and rapid stirring heat dissipation; When the temperature of nitric acid solution returns to normal temperature, diphosphoric acid 3L is added in the solution, Stir evenly; Add 5L of sulfonic acid, 5L of monobutyl ether, 1L of other surfactants, 5L of adsorbent, etc. into the above solution, and stir evenly to obtain the surface treatment solution for the inner wall of the packaging container.

Embodiment 2

[0029] First, prepare a 100L acid-resistant and corrosion-resistant open container; calculate the volume required for each raw material according to the volume ratio (29L of nitric acid; 1L of sulfonic acid; 1L of diphosphoric acid; 1L of monobutyl ether; 1L of zeolite; 62L of water; other adsorption Add 29L of nitric acid to the required water slowly, and quickly stir to dissipate heat; when the temperature of the nitric acid solution returns to normal temperature, add 1L of diphosphoric acid to the solution , Stir evenly; Add 1L of sulfonic acid, 1L of monobutyl ether, 1L of other surfactants, 5L of adsorbent, etc. into the above solution, and stir evenly to obtain the surface treatment solution for the inner wall of the packaging container.

Embodiment 3

[0031] First, prepare a 100L acid-resistant and corrosion-resistant open container; calculate the volume required for each raw material according to the volume ratio (24L of nitric acid; 3L of sulfonic acid; 2L of diphosphoric acid; 3L of monobutyl ether; 1L of zeolite; 62L of water; other adsorption Add 24L of nitric acid to the required water slowly, and quickly stir to dissipate heat; when the temperature of the nitric acid solution returns to normal temperature, add 2L of diphosphoric acid to the solution , Stir evenly; Add 3L of sulfonic acid, 3L of monobutyl ether, 1L of other surfactants, 5L of adsorbent, etc. into the above solution, and stir evenly to obtain the surface treatment solution for the inner wall of the packaging container.

Abstract

The invention relates to a liquid crystal packaging container inner wall surface treatment formula. The liquid crystal packaging container inner wall surface treatment formula comprises, by volume, 19-29 parts of nitric acid, 1-5 parts of sulfonic acid, 1-3 parts of diphosphonic acid, 1-5 parts of monobutyl ether, 1 part of a surfactant, 5 parts of an adsorbent and 62 parts of water. According to the liquid crystal packaging container inner wall surface treatment formula, in actual surface treatment, a protective film can be formed on the inner wall of a metal container, the corrosion resistance of the inner wall is improved, and precipitation of matrix elements is reduced; and in addition, raw materials of the formula are easy to obtain, operation is easy, and processing of the formula is easy to achieve.

Description

technical field [0001] The invention relates to a surface treatment formula, in particular to a surface treatment formula for the inner wall of a liquid crystal packaging container. Background technique [0002] In recent years, liquid crystal materials used in liquid crystal display devices are stored in metal packaging containers, but the inner walls of metal packaging containers are easily corroded by the materials contained inside, which affects the quality of materials; as time goes by, metal packaging Elements of the matrix material of the container itself will precipitate and produce new chemical changes, which is not conducive to long-term storage and greatly shortens the service life of the storage container. [0003] In order to meet the high requirements of the liquid crystal industry for packaging containers, it is necessary to carry out special treatment on the inner wall of the liquid crystal packaging container. Reducing the amount of element precipitation and...
