Description
Technical Field
The invention belongs to the technical field of color removing agents, and particularly relates to a color removing agent for a dyed plastic part in printing and dyeing production and a using method thereof.
Background
Plastic parts (such as a winding shaft and the like) can be dyed simultaneously in the fiber printing and dyeing production process, if dyes on the colored parts are dissolved out in the dyeing process, the fiber dyeing effect is inevitably influenced, color cross can be seriously caused, and therefore, the dyed plastic cannot be reused in the printing and dyeing process. The dyed plastic piece is repeatedly used after being subjected to color removal treatment, and has important significance for reducing industrial cost, saving energy and realizing green production. However, the conventional physical method for removing color of plastics involves benzene series and other organic solvents, which causes secondary pollution and high cost.
Disclosure of Invention
The invention aims to provide a coloring agent for a dyed plastic part in printing and dyeing production and a using method thereof aiming at the defects of the prior art. The invention takes acid as a catalyst, and the color removing agent realizes the high-efficiency color removal of plastic parts under the synergistic action of the penetrant, almost no waste liquid is generated, and the invention is high-efficiency and environment-friendly.
In order to achieve the purpose, the invention adopts the following technical scheme:
a color remover for dyed plastic parts in printing and dyeing production comprises A, B components in parts by weight, wherein the component A comprises 10 ~ 95 parts of calcium hypochlorite, 10 ~ 95 parts of magnesium hypochlorite, 10 ~ 95 parts of sodium hypochlorite, 1 ~ 10 parts of potassium hypochlorite, 1 ~ 5 parts of CTAB and 1 ~ 5 parts of SDS, and the component B comprises 1 ~ 1 parts of oxalic acid00 parts of acetic acid 1 ~ 100 parts, hydrochloric acid 1 ~ 3 parts and H2SO41 ~ 35 parts.
The method for using the color remover comprises the following steps: adding the component A and the component B into water and uniformly mixing under stirring, placing a dyed plastic piece to be treated under the liquid surface, filtering out the plastic piece after the color is faded, washing the plastic piece with clear water and drying the plastic piece; the filtrate is reused.
The invention has the beneficial effects that:
(1) the method utilizes the water-soluble color removing agent to rapidly remove the dye on the plastic part by a catalytic degradation method, and the solution used in the production process can be recycled, so that almost no waste liquid is generated, and the method is efficient and environment-friendly;
(2) the treatment cost of the dyed plastic part is lower than 200 yuan/ton, the value of the dyed plastic part is improved to 8000 yuan/ton from less than 5000 yuan/ton after the color removal treatment, and the cost can be saved by about 3000 yuan/ton.
Drawings
FIGS. 1 and 2 are graphs showing the change in color of a dyed tube before and after treatment with the color-removing agent of the present invention.

Example 3
A color remover for dyed plastic parts in printing and dyeing production comprises A, B components in parts by weight, wherein the component A comprises the following raw materials in parts by weight: 55 parts of calcium hypochlorite, 95 parts of magnesium hypochlorite, 55 parts of sodium hypochlorite, 1 part of potassium hypochlorite, 3 parts of CTAB and 3 parts of SDS; the component B comprises the following raw materials: 50 parts of oxalic acid, 100 parts of acetic acid, 1 part of hydrochloric acid and H2SO435 parts of (A).
Example 4
A color remover for dyed plastic parts in printing and dyeing production comprises A, B components in parts by weight, wherein the component A comprises the following raw materials in parts by weight: 45 parts of calcium hypochlorite, 45 parts of magnesium hypochlorite, 55 parts of sodium hypochlorite, 5 parts of potassium hypochlorite, 3 parts of CTAB and 3 parts of SDS; the component B comprises the following raw materials: oxalic acid 60 parts, acetic acid 1 part, hydrochloric acid 2 parts and H2SO415 parts.
Color removal of the plastic printing and dyeing tube: the component A and the component B of the color remover are added into water and mixed evenly under stirring, a plastic printing and dyeing pipe to be treated is placed under the liquid level, the printing and dyeing pipe is filtered out after color fading is completed, and the printing and dyeing pipe is washed clean by clear water and dried; the filtrate is reused. The using effect is shown in figures 1 and 2, the plastic printing and dyeing tube dyed by various dyes is milky white after being treated by the color removing agent, so that the recycling of the plastic is ensured, and the plastic printing and dyeing tube is green and environment-friendly.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
