Description
Technical field
The utility model relates to the component of graphitizing furnace, specifically a kind of band coating graphite heater.
Background technique
Graphite heater refers to that the electric furnace made of graphite material heats heater part.Graphite have excellent conduction,
Heating conduction is that graphite is commonly used in electric furnace as heater in special industrial furnace.Graphite electrode is selected to do in early days in industrial furnace
Heater, the oxidation rate and evaporation rate of graphite influence the service life of heater, when vacuum degree is 10-3~10-4mmHgWhen, make
It should be at 2300 DEG C or less with temperature.In protective atmosphere (logical H2、N2, Ar etc.) when, using temperature up to 3000 DEG C.Graphite cannot be
It is used in air, otherwise can occur to aoxidize and consume.
Boron nitride has a variety of excellent performances, is widely used in insulator, the automatic welding of high voltagehigh frequency electricity and plasma arc
Connect the coating of high temperature resistant frame, the material of high-frequency induction furnace, the solid phase admixture of semiconductor, atomic pile structural material,
Prevent the packaging material of neutron irradiation, the pass-through box of radar, the medium of radar antenna and constituent of rocket engine etc..Due to
With excellent greasy property, the release agent as high-temperature lubricant and a variety of models.The boron nitride of molding can manufacture high temperature resistant
Crucible and other products.
It in the prior art, is the inoxidizability and wearability that improve graphite body, if application publication number is CN 203024440
" a kind of solar energy hot-cast socket heating device " disclosed in the utility model patent of U, in the technical solution, by graphite, carbon
The setting of heater surface made of SiClx, refractory metal alloy etc. is using wrapping layer made of high-temperature resistant thermal insulating material.But simultaneously
Not specifically disclose the specific composition of the wrapping layer.
Utility model content
The purpose of the utility model is to provide a kind of band coating graphite heaters, fundamentally solve graphite heater
The problem of oxidation damage, has many advantages, such as that antioxygenic property is good, long service life.
To achieve the above object, the utility model provides following technical solution: the band coating graphite heater includes
Graphite heater, the anti oxidation layer being arranged on graphite heater, are characterized in that: anti oxidation layer is boron carbide and phenolic aldehyde tree
Rouge coating;Anti oxidation layer is attached on graphite heater by transition zone, and transition zone is phenolic resin, epoxy resin, aldehyde ketone tree
Rouge, furane resins, polyamide coating.
Although the utility model has the beneficial effects that graphite, silicon carbide, phenolic resin and epoxy resin etc. belong to it is common
Material, but be incorporated into the service life for extending graphite heater, the prior art there is no similar technical solution.?
Boron carbide and phenolic resin are uniformly dispersed by coating material, when in use, transition zone by organic solvent in anti oxidation layer
Organic material is dispersed in organic solvent (ethyl alcohol or acetoacetic ester), and phenolic resin in anti oxidation layer can have with transition zone
Machine material (phenolic resin, epoxy resin, aldehyde ketone resin, furane resins, polyamide) combines, to ensure that boron carbide
Evenly dispersed and stable coating.To finally improve the inoxidizability of graphite heater, and prolong its service life.
Detailed description of the invention
Fig. 1 is the using state structure diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
Below in conjunction with Fig. 1 ~ 2, the content of the utility model is described in detail by specific embodiment.The band coating graphite hair
Hot body includes graphite heater 1, the anti oxidation layer being arranged on graphite heater 13.Wherein, anti oxidation layer 3 is boron carbide and phenol
Urea formaldehyde coating;Anti oxidation layer 3 is attached on graphite heater 1 by transition zone 2, and transition zone 2 is phenolic resin, asphalt mixtures modified by epoxy resin
Rouge, aldehyde ketone resin, furane resins, polyamide coating.
The utility model the preparation method is as follows:
Step 1, boron nitride, phenolic resin, alcohol are mixed and stirs evenly obtained coating paste, it is spare;
Step 2, by graphite heater surface phenolic resin, epoxy resin, aldehyde ketone resin, furane resins, polyamide resin
The uniform brushing naturally dry of the organic solvents mixed solution such as at least one of rouge etc. and ethyl alcohol or acetoacetic ester;
Step 3, coating naturally dry made from uniform squeegeeing step 1 after the graphite heater made from step 2 dries;
Step 4, will brush the graphite heater that finishes install to be passed through at 950 ~ 1000 DEG C of graphitizing furnace inert gas every
Carbonization treatment is carried out in the retort of exhausted air to get finished product.
Description of symbols:
1 graphite heater
2 transition zones
3 anti oxidation layers
4 graphitizing furnaces.
