Problems solved by technology

However, when it is used on the postoperative wound of the mantle of the pearl mussel, its shortcomings will be highlighted, mainly: the solidification time of the glue is longer (needing 6 to 10 seconds), and the drainage performance is poor Wait
This makes the postoperative wound of pearl-growing mussels unable to bond quickly, and dirty water and foreign matter cannot completely avoid entering the wound, so it is difficult to avoid the occurrence of dirty beads and spit beads, and the mortality rate of pearl-growing mussels still cannot be effectively reduced. reduction of

preparation example Construction

[0058] A preparation method of an adhesive is prepared by using n-butyl α-cyanoacrylate and isobutyl α-cyanoacrylate as main components and adding an appropriate amount of stabilizer.

[0059] Added stabilizers include: hydroxymethylcellulose, hydroquinone and toluenesulfonic acid.

[0060] The use of the adhesive prepared according to the above method is applied to the postoperative wound of the mantle of the pearl clam and the visceral mass.

[0061] According to a kind of adhesive prepared by the above-mentioned method, its mass percent component is:

[0062] α-n-butyl cyanoacrylate 50-90%;

[0063] α-isobutyl cyanoacrylate 8-48%;

[0064] Hydroxymethylcellulose 1.5-5%;

[0065] Hydroquinone 0.2~1.2%;

[0066] Toluenesulfonic acid 0.2~1.1%.

[0067] The adhesive provided by the present invention uses butyl cyanoacrylate with superior performance: n-butyl α-cyanoacrylate and isobutyl α-cyanoacrylate as its main components. After the complex stabilizer toluene sulfonic ac...

Abstract

An adhesive for the wound of the pearl-culturing clam is proportionally prepared from alpha-butyl cyanoacrylate, alpha-isobutyl cyanoacrylate, hydroxymethyl cellulose, phenyldiphenol, and toluenesulfonic acid. Its advantages are short setting time, high water-proofing nature, and low dead rate of clam.

Description

technical field [0001] The invention relates to the cultivation technology of freshwater pearls, and relates to an adhesive. Background technique [0002] In the cultivation process of freshwater pearls, inserting slices or cores on the mantle or viscera of pearl-growing mussels is a key step that directly affects the survival rate of pearl-growing mussels and thus affects the yield and quality of pearls. The so-called insertion means that after the shell of the pearl oyster is opened, a small incision is cut on the epithelial cells of its mantle, and the pre-prepared small pieces of epithelial cells are inserted into the incision to form a seedless pearl. The so-called nucleus insertion is to insert the pre-prepared bead nucleus together with the small cell pieces into the incision of the epithelial cells of the mantle. Similarly, the epithelial cells wrap the bead nucleus to form a pearl sac, and then secrete nacre. Eventually nucleated pearls are formed. It is not diffi...
