Fastly, so that the levelability of coating is lower, it is unfavorable for the problem of follow-up coating combines；In addition, since aluminium base receiving does not live
The drying of higher temperature twice is beneficial to prevent aluminium base yield strength and tension is strong using three different grades of temperature
The decline of degree is conducive to the raising of pull ring material mechanical property.
It is in argon when carrying out first time coating to material volume 5. material volume is placed in specific environment when carrying out coating
Compression ring border, vacuum degree 2.0 × 10-2~3.5 × 10-2Pa, temperature be 300~400 DEG C, carry out under conditions of 200-300V, due to
It applies to be high-temperaure coating when first time coating, is related to solidification process, it is desirable that resistant to high temperatures after solidification and invariance, therefore first
Ar gas environment is selected when secondary coating, the metastable energy level of argon gas only has the energy of 11.5eV, and metastable energy level is lower, the first ionization
Can be smaller, 2.0 × 10-2~3.5 × 10-2It, can be with the property of various raw materials in effective protection high-temperaure coating under the vacuum degree of Pa
Matter is not destroyed, and is formed and is protected to high-temperature resistant coating, prevented ionization energy excessively high and destroy the ingredient of raw material；Carrying out the
When secondary and third time coating in helium environment, the metastable energy level of helium high energy metastable helium atomic in the high temperature environment is
11.7eV can generate metastable atom or molecule with higher-energy, longer life, these metastable particles and other particles
Collision can release free electron, can connect the molecule in raw material closer, improves levelability, enhances and aluminium base
With the adhesion strength of high-temperaure coating.
6. being filled when being mixed to high temperature resistant inner coating and epoxy external coating using the special type of coating agitating and heating
It sets, the coating in storage device is drawn out and is transported in heating device by the conveying device of the device, is heating coating
It is heated in device, reduces the gap between molecule, so that the molecule in close in each raw material combines, be conducive to improve internal layer painting
The adhesive force of material and outer layer coating；It is helical form by heat exchange tube design, increases the contact area of heat exchanger tube and liquid heating medium

Intensity is in higher level, and yield strength reaches as high as 385MPa, and tensile strength reaches as high as 205MPa, and contrast groups
In, since when coating coats, the temperature of tri- heating zones baking oven A and baking oven B sets identical, yield strength and tensile strength
Decline is obvious, this shows the different grades of temperature setting of baking oven A and baking oven B, and it is cured can either to meet inner coating low temperature needs
It is required that and can be avoided and to solidify incomplete problem because temperature is too low, while also avoiding causing to solidify because temperature is excessively high
Excessive velocities are unfavorable for the problem of follow-up coating combines so that the levelability of coating is lower；In addition, since aluminium base is held
By the drying of incessantly higher temperature twice, using three different grades of temperature, be beneficial to prevent aluminium base yield strength and
The decline of tensile strength is conducive to the raising of pull ring material mechanical property.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
