specific Embodiment approach 1

[0014] Specific embodiment one: the surface modification method of a kind of fish breeding pottery pot of this embodiment prevents white eggs is carried out according to the following steps:

[0015] (1) Sensitization of clay pots: immerse the pot in the aqueous solution of stannous chloride and shake for 5 to 120 seconds, take it out and immerse in deionized water and shake for 5 to 120 seconds, in which the aqueous solution of stannous chloride contains 0.5 to 10.0 g / L Stannous chloride, 1.0~50.0 mL / L 37% concentrated hydrochloric acid and 0.1~5.0 g / L hydroxylamine hydrochloride;

[0016] (2) Preparation of metallization solution: Dissolve the complexing agent with a concentration of 0.5-6.0 g / L, the silver nitrate with a concentration of 0.1-0.8 g / L and the copper salt with a concentration of 0.6-3.0 g / L in order to remove In deionized water, adjust the pH to 11.0-12.0 with sodium hydroxide and age for 24 hours, then add ethanol with a concentration of 3-8 mL / L and glyoxyli...

specific Embodiment approach 2

[0020] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the complexing agent described in step (2) is one or two of sodium citrate, sodium gluconate, potassium pyrophosphate or sodium malate The combination. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the copper salt described in step (2) is a kind of in copper acetate or copper nitrate. Others are the same as in the first embodiment.

Abstract

The invention relates to a method for modifying the surface of fish breeding clay pots to prevent white eggs, so as to prevent fish eggs from appearing white eggs in the hatching process. The invention aims to solve the problem that the surface of the current fish breeding earthen pot is easy to accommodate dirt and breed bacteria, which causes mildew and whitening in the hatching process of fish eggs. A method for surface modification of fish breeding clay pots to prevent white eggs: (1) sensitization of pottery pots; (2) preparation of metallization solution; (3) preparation of antibacterial layer; The preparation of the hydrophobic layer obtains a film layer with excellent antifouling and antibacterial properties on the surface of the fish breeding clay pot. A method for surface modification of fish breeding pots to prevent white eggs can improve the surface tension of pots, make them have excellent anti-fouling performance, and can inhibit harmful bacteria, thereby effectively preventing fish eggs from becoming moldy and developing during hatching. white phenomenon.

Description

technical field [0001] The invention belongs to the field of non-conductor surface modification, and relates to a method for preventing white eggs by modifying the surface of clay pots for fish breeding. Background technique [0002] For the aquarium field, two issues are crucial: fish health and fish reproduction. The health of fish is inseparable from a good water environment, and the reproduction of fish is not only related to the water environment, but also closely related to the breeding place. [0003] For a good aquarium system, the self-purification ability of the aquarium system itself is fundamental to ensure that it provides a high-quality water environment for ornamental fish. In the aquarium system, fish feces and excess feed that have not been removed from the aquarium system will eventually be decomposed under the action of heterotrophic bacteria in the entire aquarium system, and the decomposition product of heterotrophic bacteria to protein is ammonia. Amm...
