Problems solved by technology

[0002] Red is the basic and indispensable tone in the embossing art production process, but compared with other shades of materials, red materials tend to brown easily and lose their original "true color"
Such as the red eucalyptus ( Lorpetalum Chinese (R.Br) Oliver var. Rubrum Yieh), its leaves are small and easy to use in the embossing process, and it is a more valuable embossing material. There is no ready-made answer in the existing technology, and its economic value is difficult to improve

Embodiment 1

[0019] A kind of method for protecting the color and shape of the leaves of the present invention comprises the following steps:

[0020] first step. Prepare a color-retaining reagent. The formula of the color-retaining reagent is: by weight, 17.0 g of citric acid, 3.0 g of sodium hydroxide, 1.5 g of hydrochloric acid with a concentration of 10%, 0.5 g of sodium lauryl sulfate, and 4.0 g of sucrose.

[0021] The second step. Select mature and intact red leaves of Hongjimu, wash away the impurities or dust on the surface, and then soak in the prepared color-preserving reagent for 30 hours.

[0022] third step. After immersing for 30 hours, take out the red leaves of eucalyptus and rinse them with clear water to wash off the residual reagent on the leaves, and dry the water on the surface of the leaves.

[0023] The color-preserving reagent container should be tightly closed, and each of the leaves must be fully immersed in the reagent, and each of the leaves should be separa...

Embodiment 2

[0031] A kind of method for protecting the color and shape of the leaves of the present invention comprises the following steps:

[0032] first step. Prepare a color-retaining reagent. The formula of the color-retaining reagent is, by weight, 25.0 g of citric acid, 5.0 g of sodium hydroxide, 3.5 g of hydrochloric acid with a concentration of 10%, 1.5 g of sodium lauryl sulfate, and 6.0 g of sucrose.

[0033] The second step. Select mature and intact red leaves of Hongjimu, wash away the impurities or dust on the surface, and then soak in the prepared color-preserving reagent for 40 hours.

[0034] third step. After immersing for 40 hours, take out the red leaves of the eucalyptus and rinse them with clear water to wash off the residual reagent on the leaves, and dry the water on the surface of the leaves.

[0035] The color-preserving reagent container should be tightly closed, and each of the leaves must be fully immersed in the reagent, and each of the leaves should be se...

Embodiment 3

[0043] A kind of method for protecting the color and shape of the leaves of the present invention comprises the following steps:

[0044] first step. Prepare color retention reagent, the formula of color retention reagent is: by weight, citric acid 21.0 g, sodium hydroxide 4.0 g, hydrochloric acid 2.5 g and concentration are 10%, sodium lauryl sulfate 1.0 g, sucrose 5.0 g;

[0045] The second step. Select mature and intact red leaves of Hongjimu, wash away the impurities or dust on the surface, and then soak in the prepared color-preserving reagent for 35 hours.

[0046] third step. After immersing for 35 hours, take out the red leaves of eucalyptus and rinse them with clear water to wash off the residual reagent on the leaves, and dry the water on the surface of the leaves.

[0047] The color-preserving reagent container should be tightly closed, and each of the leaves must be fully immersed in the reagent, and each of the leaves should be separated to ensure that each par...

Abstract

The invention provides a method for protecting color and keeping shape of China loropetal leaves, and relates to a method for protecting color and keeping shape of plant leaves. The method comprises the following steps: 1. preparing a color protective reagent from citric acid, sodium hydrate, hydrochloric acid, sodium dodecyl sulfate and sucrose; 2. selecting mature and undamaged red China loropetal leaves, and soaking the leaves in the prepared color protective reagent for 30-40 hours; 3. taking out the soaked leaves, then rinsing the red China loropetal leaves with clear water, and sopping up the water on the surfaces of the leaves; 4. clamping the leaves with splints and then drying the processed leaves for 40-60 seconds in a microwave oven; and 5. pressing the dried leaves for 18-30 hours by a repressing drying method so that the leaves are fully dried. The method provided by the invention has the following beneficial effects: dried red China loropetal leaves formed by the method have the advantages of good flexibility, good flatness, beautiful appearance, no browning phenomenon and brighter color compared with that of fresh leaves, thus having higher ornamental value and higher economic value.

Description

technical field [0001] The invention relates to a method for protecting the color and shape of plant leaves, in particular to a method for protecting the color and shape of the leaves of eucalyptus. Background technique [0002] Red is the basic and indispensable tone in the process of embossing art production, but compared with materials of other tones, red materials tend to brown easily and lose their original "true color". Such as the red red eucalyptus ( Lorpetalum Chinese (R.Br) Oliver var. Rubrum Yieh), its leaves are small and easy to use in the embossing process, and it is a more valuable embossing material. There is no ready-made answer in the prior art, and its economic value is difficult to improve. Contents of the invention [0003] The invention aims at overcoming the above-mentioned shortcomings of the prior art and meeting the market demand, and provides a method for protecting the color and shape of the leaves of the eucalyptus. This method begins with ...
