Embodiment 1

[0018] A tea stain cleaner, the main component of the tea stain cleaner is sodium percarbonate, the average particle diameter of the sodium percarbonate particles is 300 μm, the surface of the sodium percarbonate particles is provided with a coating layer, the The coating is made from a mixture of citric acid and sodium citrate. The preparation method of the tea stain cleaner is as follows: respectively take citric acid and sodium citrate and dissolve them in deionized water to obtain a mixed solution of citric acid and sodium citrate. In the mixed solution, the total mass of citric acid and sodium citrate Ratio of 35%, then spray sodium percarbonate particles with the mixed solution in the fluidized bed, after spraying is completed, dry at 55°C to get final product; wherein, the mass ratio of citric acid and sodium citrate is 2:5 .

Embodiment 2

[0020] A tea stain cleaner, the main component of the tea stain cleaner is sodium percarbonate, the average particle diameter of the sodium percarbonate particles is 500 μm, the surface of the sodium percarbonate particles is provided with a coating layer, the The coating is made from a mixture of citric acid and sodium citrate. The preparation method of the tea stain cleaner is as follows: respectively take citric acid and sodium citrate and dissolve them in deionized water to obtain a mixed solution of citric acid and sodium citrate. In the mixed solution, the total mass of citric acid and sodium citrate Ratio is 40%, then spray sodium percarbonate particles with the mixed solution in the fluidized bed, after spraying is completed, dry at 60°C to get final product; wherein, the mass ratio of citric acid and sodium citrate is 2:6 .

Embodiment 3

[0022] A tea stain cleaner, the main component of the tea stain cleaner is sodium percarbonate, the average particle diameter of the sodium percarbonate particles is 800 μm, the surface of the sodium percarbonate particles is provided with a coating layer, the The coating is made from a mixture of citric acid and sodium citrate. The preparation method of the tea stain cleaner is as follows: respectively take citric acid and sodium citrate and dissolve them in deionized water to obtain a mixed solution of citric acid and sodium citrate. In the mixed solution, the total mass of citric acid and sodium citrate Ratio is 50%, then spray sodium percarbonate particles with the mixed solution in the fluidized bed, after spraying is completed, dry at 70°C to get final product; Wherein, the mass ratio of the citric acid and sodium citrate is 2: 7 .

Abstract

The invention aims at solving the problem that tea stain still exists after cleaning with sodium percarbonate and provides a tea stain detergent and a preparation method thereof. The main component ofthe tea stain detergent is mainly the sodium percarbonate; the surfaces of sodium percarbonate particles are provided with coating layers respectively; and each coating layer is mixed by citric acidand sodium citrate. By adopting the tea stain detergent, the tea stain at any part in a tea set can be fully cleaned; and more importantly, the sodium percarbonate cannot cause the problem of raisingdust and is higher in stability and easy to store.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a tea stain cleaning agent and a preparation method thereof. Background technique [0002] Tea contains theophylline. After the tea set is used for a long time, theophylline is easy to adhere to the surface of the tea set. The tea dirt retained on the inner wall of the tea set is referred to as tea stains or tea stains. Tea stains are produced due to the oxidation reaction between tea polyphenols in tea and metal substances in tea rust in the air. Various metals such as cadmium, lead, iron, arsenic, mercury and nitrite in tea stains are harmful to the body. High content of harmful substances. Therefore, those who have the habit of drinking tea should always clean the tea stains on the inner wall of the tea set in time. [0003] But tea dirt is difficult to clean. Daily tea set cleaning with bleach, detergent powder, detergent, etc. There are also various ...
