Problems solved by technology

Since the main component of the egg shell is calcium carbonate, which is brittle, fragile and easy to break, it is very difficult to process
First of all, when choosing the type of egg material, it is necessary to choose eggs with high hardness and large individuals. At present, only ostrich eggs can be used in the domestic market, but this kind of eggs is expensive and the quantity is small.
Second, because the shell of the egg is fragile and easy to break, when choosing the subject matter of the hollowed-out carving pattern, the strokes of the selected pattern should be thicker and the graphics should be simpler, so that the overall effect of the hollowed-out egg carving crafts is not exquisite enough, and the texture of the egg The thinner the shell, the rougher the crafting effect
The third is that even if you choose a hard egg and a rough pattern, you still have to be careful when hollowing out, which will take a long time and cost a lot.
Fourth, skilled workers must undergo a long period of special skill training before they can work on this craft.
Fifth, the loss rate is particularly large. It is well known that the loss rate of goose eggs and eggs is more than 90% when using manual carving knives and electric sharpening knives.
In summary, the existing egg hollow carving technology has disadvantages such as difficult hollow carving, long processing time, high cost, high egg loss rate, rough hollow pattern, etc., which limits the development of egg hollow carving technology

example 1

[0018] Example 1: Crane quail egg corrosion hollow carving method, carried out by the technical process of the present invention, acid corrosion with a purity of 95% nitric acid, made into a concentration of 15% nitric acid solution, soaked for 10 minutes to take out the eggs. The egg membrane is separated from the eggshell, and the egg body is filled with a 15% nitric acid solution, which stays in the egg body for 15 minutes.

example 2

[0019] Example 2: Egg corrosion engraving method is carried out according to the technological process of the present invention, and the purity of acid corrosion is 95%, and the nitric acid solution with a concentration of 20% is prepared and soaked for 15 minutes. The egg membrane is separated from the eggshell, and the egg body is filled with a 15% nitric acid solution, which stays in the egg body for 15 minutes.

example 3

[0020] Example 3: The duck egg corrodes hollow out engraving method, carries out by technological process of the present invention, and acid corrosion is 95% nitric acid with purity, is made into the nitric acid solution of 25% concentration, soaks 20 minutes. The egg membrane is separated from the eggshell, and the egg body is filled with a 15% nitric acid solution, which stays in the egg body for 15 minutes.

Abstract

The egg hollowing-out engraving technique includes the following steps: pumping out egg liquid, drawing pattern on the surface of egg, adding acid-resisting protective layer in the drawing line, drying, making acid corrosion, separating egg film from egg shell and washing with medical ethyl alcohol. Said invention is simple and convenient, short in processing time and low in cost.

Description

(1) Technical field: [0001] The invention relates to an egg hollow carving technology, in particular to an egg corrosion hollow carving method. (two) background technology: [0002] At present, the egg hollow carving technology mostly adopts manual carving and electric grinding wheel grinding. Since the main component of egg shells is calcium carbonate, which is brittle, fragile and easy to break, it is very difficult to process. First of all, when choosing the type of egg material, it is necessary to choose eggs with high hardness and large individuals. At present, only ostrich eggs can be used in the domestic market, but this kind of eggs is expensive and the quantity is small. Second, because the shell of the egg is fragile and easy to break, when choosing the subject matter of the hollowed-out carving pattern, the strokes of the selected pattern should be thicker and the graphics should be simpler, so that the overall effect of the hollowed-out egg carving crafts is not...
