Description

Technical Field

[0001] The present invention belongs to the field of preparation of plant specimens, and particularly relates to a method for preparing a large-scale kelp specimen. Background Art

[0002] Most of the existing methods for preparing plant specimens use natural air drying, which is more suitable for smaller plants. For large plant specimens, technologies such as assembly, splicing and folding are mostly used for preparation, and the whole of the specimen cannot be completely shown. Making large plant leaf specimens cannot be well and effectively preserved, and problems such as discoloration, deformation, mildew, and damage often occur. Marine algae plants are softer and thinner than land plant leaves, have more water, and do not have a well-developed cuticle, palisade tissue, fiber tissue and conducting tissue like land plants. Therefore, seaweed plants such as kelp cannot effectively support the leaf surface, and most marine plant leaves become very thin after dehydration and are prone to deformation. Using the existing technology for preparation is difficult, not easy to fix, and technical problems such as wrinkles, cracks, mildew, and color fading are likely to occur in the specimens. Summary of the Invention

[0003] The present invention provides a method for preparing a large-scale kelp specimen for the above technical problems. The method can successfully prepare a relatively smooth and complete kelp specimen that is mildew-proof, color-fastness-proof, crack-proof and can be preserved for a long time and is easy to maintain.

[0004] The present invention is realized by the following technical solutions:

[0005] A method for preparing a large-scale kelp specimen, and the specific steps of the method are as follows:

[0006] First step, wash and cook the kelp;

[0007] Second step, first lay a layer of cotton yarn net on a flat plate with a smooth surface that is not easy to deform and rust, spread the cooked kelp flat on the flat plate, absorb the excess water on the kelp, level the kelp, the side close to the flat plate is called the lower leaf surface, and the upward side is called the upper leaf surface. Cover a layer of cotton yarn net on the upper leaf surface, place absorbent paper on the cotton yarn net and press it with a heavy plate-shaped body. After 10 - 13 hours, open and arrange the kelp to make it flat, and brush a layer of white latex around the upper leaf surface of the kelp. Leave the middle of the upper leaf surface empty and brush the white latex after one day. When the white latex is almost dry, uniformly brush a layer of white latex on the surface of the upper leaf surface. After the newly brushed white latex is completely dry, check whether the lower leaf surface of the kelp is flat. If there are uneven places, brush a layer of white latex on the corresponding upper leaf surface of the uneven places separately;

[0008] Step 3: After 48 hours, turn the kelp over and check and arrange whether there are wrinkles on the leaf surface. If there are wrinkles, apply another layer of white latex on the corresponding upper leaf surface. After it dries completely, check the flatness of the kelp leaf surface. The lower leaf surface of the kelp reaches complete flatness, and then pour crystal resin on the upper leaf surface. Pour crystal resin and curing agent on the upper leaf surface of the kelp according to a volume ratio of 3:1. After the crystal resin on the upper leaf surface is completely cured, pour it on the lower leaf surface of the kelp according to a volume ratio of 3:1 of crystal resin and curing agent. After the crystal resin on the lower leaf surface is completely cured, arrange the four sides of the kelp for mounting.

[0009] Further, the length of the kelp is more than 240 cm.

[0010] Further, add 0.2-1.0% salt to the water for boiling the kelp.

[0011] Further, the flat plate is a stainless steel flat plate or an aluminum plate.

[0012] The beneficial effects of the method of the present invention compared with the prior art: The large kelp specimens prepared by the method of the present invention can ensure that they will not mildew, become damp or crack, can achieve complete flatness and color preservation, and can be truly permanently preserved. Specific embodiments

[0013] The technical solution of the present invention will be further explained below through examples, but the protection scope of the present invention is not limited by any form of the examples.

[0014] Example 1: A preparation method of a large kelp specimen, and the specific steps of the method are as follows:

[0015] Step 1: Wash a 240-cm long kelp clean, and then put it in a pot and cook it. Put 20 g of salt in 10 kg of the cooked water body to keep the color of the kelp.

[0016] The second step is to spread the kelp on a flat stainless steel plate and use newspapers to absorb excess water and level the kelp. You can also use an aluminum plate, but not a wooden board. Using a wooden board will easily deform the kelp or make it stick to the board and cannot be completely removed. The side that is close to the plate is called the lower leaf surface, and the side facing up is called the upper leaf surface. Cover the flattened upper leaf surface of the kelp with a layer of cotton gauze, put 2 layers of newspapers on the cotton gauze and press it with an iron plate. After 12 hours, open it and slightly tidy up the leaf surface of the kelp to make its surface flat. Brush a layer of white latex around the upper leaf surface of the kelp. In this step, only the upper leaf surface of the kelp can be brushed with white latex. If white latex is brushed on both sides of the kelp at the same time, wrinkles are likely to occur and it cannot be leveled later. The middle part of the leaf surface on the kelp is vacated and white glue is applied every other day. When the white glue is quick-drying, the time of white glue drying is different according to the thickness of the kelp and the weather for making. Generally, after 4-10 hours of brushing white glue on the middle part, the white glue quick-drying reaches the degree of quick-drying. The present embodiment is a 240cm kelp made in May. After 9 hours of brushing white glue on the middle part, a layer of white glue is uniformly applied on the leaf surface thereon. After the white glue is completely dried, check whether the leaf surface under the kelp is smooth. If there is uneven place, brush a layer of white glue on the uneven place separately; This step is very critical. The researchers initially carried out a disposable brushing of white glue on the kelp. As a result, the middle part of the kelp is prone to produce wave-shaped wrinkles, and further drying is prone to cracking. This gradual brushing of white glue has been studied out through repeated attempts, and the periphery of the kelp is brushed first, and after the periphery is qualitatively characterized, the method of brushing the middle part is brushed again. The smoothness of the kelp leaf surface can be guaranteed as much as possible by brushing white glue on the wrinkled place again.

[0017] The third step is to turn the kelp over after 48 hours to check if there are any wrinkles on the lower leaf surface. If there are wrinkles, brush a layer of white glue on the upper leaf surface corresponding to the wrinkles. Wait for the white glue to dry. Make sure the kelp is completely flat and then pour crystal resin on its upper leaf surface. Use crystal resin and curing agent in a ratio of 3:1 to pour on the upper leaf surface of the kelp. After it cures for 48 hours, pour the lower leaf surface over again. After it is completely cured, arrange the kelp around and frame it, with the lower leaf surface facing outwards.

[0018] In the embodiment, it should be noted that when brushing white latex, try not to have bubbles, brush out an extra area around the kelp, and when pouring the crystal resin on the front of the kelp, it must not exceed the area brushed with white latex, and it must be within the range brushed with white latex. If the poured crystal resin penetrates into the back of the kelp, it will cause the kelp to directly bond with the stainless steel plate and finally cannot be separated and fail.
