specific Embodiment approach 1

[0030] Embodiment 1: This embodiment is a method for preparing a veneer veneer with photocatalytic function, which is specifically completed according to the following steps:

[0031] 1. Prepare mixed solution A:

[0032] Bismuth nitrate pentahydrate is dissolved in nitric acid to obtain mixed solution A;

[0033] The mass of bismuth nitrate pentahydrate described in step 1 and the volume ratio of nitric acid are (2mmol~4mmol):(30mL~50mL);

[0034] The concentration of nitric acid described in step 1 is 3mol / L~5mol / L;

[0035] 2. Prepare mixed solution B;

[0036] Ammonium molybdate tetrahydrate was dissolved in distilled water to obtain mixed solution B;

[0037] The quality of the ammonium molybdate tetrahydrate described in step 2 and the volume ratio of distilled water are (0.3g~0.8g):(30mL~40mL);

[0038] 3. Preparation of reaction solution:

[0039] Add mixed solution B dropwise to mixed solution A at a rate of 20 drops / min to 40 drops / min to obtain mixed solution C...

specific Embodiment approach 2

[0051] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the mass of bismuth nitrate pentahydrate described in step one and the volume ratio of nitric acid are (2mmol~3mmol):(30mL~40mL). Other steps are the same as in the first embodiment.

specific Embodiment approach 3

Abstract

The invention provides a method for preparing veneer with a photocatalytic function, relates to a veneer preparation method, and aims to solve the problems that a conventional Bi-system photocatalyticwood preparation process is high in cost, poisonous gas is easily generated during a machining process, and the photocatalytic effect is poor. The method comprises the following steps: 1, preparing amixed solution A; 2, preparing a mixed solution B; 3 preparing a reaction liquid; and 4, carrying out a hydrothermal reaction so as to obtain the veneer with the photocatalytic function and photocatalyst powder. By utilization of the veneer which is prepared through the method provided by the invention and has the photocatalytic function, 15% of RhB dye can be degraded within 12 minutes. Throughthe method, the veneer with the photocatalytic function can be obtained.

Description

technical field [0001] The invention relates to a preparation method of veneer veneer. Background technique [0002] Furniture is an indispensable article in daily life, but the release of organic pollutants in furniture has caused harm to the human body. This issue has attracted people's attention. Therefore, furniture that can degrade organic matter and be environmentally friendly is very popular. The existing related bismuth-based photocatalytic wood is processed by two pressure impregnations, and the used halide salt solution may produce toxic gas during processing. In addition, this method is to dip into one solution a first, and then dip into another solution b. The disadvantage is that, firstly, the length of the two processes and the cost increase, and secondly, the cost of the solution is wasted, because when starting from a After taking out and impregnating to b, the b solution cannot be reused. Third, it is uncontrollable. During the second impregnation, the g...
