Method for manufacturing soft algae specimen

Abstract

The invention provides a method for manufacturing a soft algae specimen. The method comprises the following steps: step one, transferring algae of a specimen to be prepared to an expansion plate in water to enable the algae to be expanded on the expansion plate; step two, putting the expansion plate into a container, flatly laying a dried material / powder on the algae, and then carrying out dryingtreatment; step three, uniformly mixing a mixed glue solution prepared from epoxy resin and polyether amine D-230, performing defoaming at a temperature of not more than 40 DEG C, pouring the defoamedmixed glue solution into a mold, carrying out standing for 7-12 hours, taking down the algae dried in the step two from the expansion plate, adhering the algae onto the glue, covering the algae withthe defoamed mixed glue, and carrying out standing for 24-48 hours until the specimen is solidified; and step four, polishing the solidified algae specimen, coating UV glue, and carrying out UV lamp irradiation curing to complete the preparation. The specimen obtained by the method provided by the invention can better preserve the original form of algae.

Description

technical field [0001] The invention belongs to the technical field of preparation of algae specimens, and in particular relates to a preparation method of mollusc specimens, which can be used for preparation of mollusc specimens such as feather algae, enteromorpha, laver and the like. Background technique [0002] Mollusca, such as feather algae, enteromorpha, seaweed, etc., are relatively soft, and the algae are scattered in the water, but after leaving the water, due to the aggregation of the water flow, they will gather together instead of the normal state in the water body. It is more difficult to operate than other algae when making specimens. [0003] The existing production method of seaweed specimens has a pressing method, which is to dry the algae body by replacing the absorbent paper several times. Because the mollusc algae body is small and delicate, in the drying process, the absorbent paper is replaced many times, which is easy to cause algae. The damage of th...

Problems solved by technology

[0003] Existing methods for making seaweed specimens include a pressing method, which is to dry the algae by replacing the absorbent paper several times. Because the mollusc algae are small and delicate, in the drying process, the absorbent paper is replaced many times, which is easy to cause algae. The damage of the body, and the pressed specimen is easy to oxidize and deform

[0004] In previous studies, it was found that if the specimen preparation method of terrestrial plants was directly used for the preparation of mollusc specimens, the completed specimens could not show the morphology of the algae well.

Among them, pre-sample drying methods include air blowing, absorbent paper pressing, or desiccant, etc. Molluscum algae are small and delicate, and the methods of blowing air and absorbent paper pressing are easy to damage the algae and affect the shape of the algae. The desiccant dries the mollusk, but the desiccant used in the existing technology is anhydrous silica gel powder and aluminum oxide. At the same time, the desiccant with the plant needs to be heated in a microwave oven to complete the drying. After using this method, the drying speed is too fast, and the algae are easy to wrinkle and deform

At the same time, the existing method of preparing terrestrial plants is to directly place the plants in the desiccant to dry and then take them out. However, molluscs are delicate and thin, and if the algae are not directly taken out of the desiccant after drying prone to breakage of algae

At the same time, molluscs stretch out in seawater. Once they are removed from the water, the soft algae will gather together with the water flow. The effect of manual expansion is not good, and it is easy to damage the algae
