Embodiment Construction

[0019] The present invention is achieved like this:

[0020] 1. The producer makes parylene powder;

[0021] 2. The producer heats and vaporizes the parylene powder into steam n;

[0022] 3. The producer cracks parylene vapor molecules into active monomer parylene vapor molecules;

[0023] 4. The producer hollows out the internal organs of the insects and dries and dehydrates the insects;

[0024] 5. The creator vapor-sprays the interior and exterior of the insect with the reactive monomer parylene;

[0025] 6. The producer sprays parylene vapor molecules on the interior and exterior of the insect to form a coating;

[0026] Compared with existing methods, this method has the following advantages:

[0027] 1. The animal specimen preparation method of the present method has high protective performance;

[0028] 2. This method is a spraying method that cannot be realized by other technologies in the spraying process;

[0029] 3, the parylene coating production method effic...

Abstract

The invention relates to a manufacture method for insect specimens coated with poly-p-xylylene. The manufacture method includes increasing the temperature of poly-p-xylylene chemical material powder in an evaporation chamber to 175 DEG C before vaporization, feeding poly-p-xylylene vapor into a splitting decomposition chamber, heating the vapor to 680 DEG C, turning poly-p-xylylene vapor moleculesinto active monomer poly-p-xylylene vapor molecules after splitting decomposition, hollowing out insects, drying and dehydrating the insects in a vacuum chamber with the temperature of 25 DEG C, spraying active monomer poly-p-xylylene vapor to inner and outer surfaces of the insects in the vacuum chamber through a thin tube, evenly adsorbing and infiltrating active monomer poly-p-xylylene molecules in the vapor to the inner and outer surfaces of the insects under a vacuum state, and forming coatings 0.1-10 micrometers in thickness through polymerization and sedimentation to obtain the insectspecimens.

Description

technical field [0001] The invention relates to a method for making an animal specimen coating, which belongs to the coating material manufacturing technology, and in particular to a method for making insect specimens coated with parylene. . Background technique [0002] At present, the insect specimen preparation methods widely used in the world include drug soaking, vacuum drying and constant temperature drying at 25°C, and the protection performance is not good. The production method of the parylene coating is that the parylene vapor molecules are evenly distributed in a vacuum chamber with a temperature of 25°C, absorbed and infiltrated and sprayed on the inner and outer surfaces of the insects, condensed and rapidly polymerized to form a thin film. The efficiency of the above-mentioned spraying method is high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the existing animal specimen preparation method tec...
