There is heat-stable ceramic marmite and the preparation method of metal magnetic conducting film
Technical field
The present invention relates to marmite and manufacture field, a kind of heat-stable ceramic marmite with metal magnetic conducting film and preparation side
Method.
Background technology
Electromagnetic oven enters common people house and becomes a reality already, and along with constantly advocating of flames of anger thermal source, electromagnetic oven is more
Showing powerful vitality, and pottery marmite is nontoxic, the kitchen tools of genuine feature other material especially can not generation
Replace.Owing to heat-stable ceramic marmite does not has magnetic conductivity, it is impossible to use on electromagnetic oven.And if electromagnetism on heat-stable ceramic marmite
Stove, is suitable for cooking requirement, consumption demand now, is the once new revolution of marmite technology, and domestic and abroad market prospect is boundless.
Summary of the invention
Heat-stable ceramic marmite owing to selling on Vehicles Collected from Market does not has magnetic conduction function, it is impossible to directly use on electromagnetic oven,
It is an object of the invention to develop electromagnetic thermal-resisting ceramic marmite, will thoroughly solve heat-resisting marmite and cannot be used for a difficult problem for electromagnetic oven.
The present invention adopts the following technical scheme that realization:
A kind of heat-stable ceramic marmite with metal magnetic conducting film, including pot, described bottom of pot body is coated with metal transfer successively
Layer, metal magnetic conducting layer and coat of metal.
Described metal transition layer thickness 0.1-0.2mm, described metal magnetic conducting layer thickness 0.2-0.5mm, described metal coating
Layer thickness 0.1-0.2mm;The gross thickness of three layers is 0.6-0.7mm.
The preparation method of the above-mentioned heat-stable ceramic marmite with metal magnetic conducting film, comprises the steps:
(1), product selection
Pottery marmite presents sintering state, and water absorption rate is more than 1%, smooth bottom product;
(2), spraying coating process flow process
Metal spraying silk is filled in spray gun, marmite product is buckled and is placed on smooth frock rotating disk, sprayed protection utensil is put
On marmite product;Sprayed protection device, for covering marmite other place in addition to bottom surface, is simultaneously used for specification spraying position.
With spray gun at marmite bottom surface fast spraying intermediate metal, transition zone as combining bottom, spraying temperature 1100 DEG C;
After cooling 5min, spray metal magnetic layer, spraying temperature 1000 DEG C;
Cooling more than 1h, polishes magnetic layer surface, then spray metal protective layer, spraying temperature 1200 DEG C with hardhead sponge.
Described metal spraying silk uses aluminium alloy, titanium alloy, Stainless Steel to constitute metal base, and its ratio is 3:2:1, makes
The tinsel of a diameter of 1.5 millimeters, the frock market such as spray gun is bought.With spray gun in hot environment, utilize tooling device
Bottom heat-stable ceramic marmite, spraying forms metallic film, sprays layer protective layer after cooling again, after placing hardening.Metal
Silk is atomized into metal microparticle in hot environment, and heat-stable ceramic glaze under high temperature action occurs slightly to soften, after softening
Glaze layer surface runs into metal microparticle and fills and leads up rapidly ceramic pan basal surface pore, along with the prolongation of spray time, metal microparticle
Just form metal coating in the heat-stable ceramic the bottom of a pan, after cooling, utilize the magnetic conduction function of metal coating just can make on electromagnetic oven
With heat-stable ceramic marmite cooking food.
Present invention have the advantage that
1, magnetic conductive film hardness is big, and pore is few, and the magnetic conduction life-span is long.
2, magnetic conductive film is the most water funk.
3, heat-stable ceramic Heat stability is good, magnetic conductive film is difficult to puncture.
4, technique is simple, it is simple to grasp, and is suitable for mass industrialized production.
5, safe devoid of risk.
6, heat radiation is slow, good heat insulation.
7, nontoxic, genuine, convenient and swift.
The present invention is reasonable in design, and the benefit using this technology maximum is by natural, nontoxic, the natural juice of ceramic cooker
Original flavor and the flames of anger of electromagnetic oven, convenient and swift combine, develop a kind of electromagnetic oven pottery marmite, adaptation modern consumer
Culinary art requirement, there is good market application foreground.
Detailed description of the invention
Below the specific embodiment of the present invention is described in detail.
A kind of heat-stable ceramic marmite with metal magnetic conducting film, including pot, described bottom of pot body is coated with metal successively
Transition zone, metal magnetic conducting layer and coat of metal.
Described metal transition layer thickness 0.1-0.2mm, described metal magnetic conducting layer thickness 0.2-0.5mm, described metal coating
Layer thickness 0.1-0.2mm;The gross thickness of three layers is 0.6-0.7mm.
Concrete preparation method is as follows:
One, preliminary preparation
(1), product selection
Product sintering state to be presented, water absorption rate is more than 1%;Bottom product smooth, there is no base bubble, glaze slag, speckle and heap
The defects such as long-pending pore.
(2), sprayed protection utensil is regular, to justify, and must not have deformation, uneven phenomenon.
(3), site environment is wanted clean, must not be polluted.
Two, spraying coating process flow process
Metal spraying silk is slowly filled in spray gun;
Product button is placed on smooth frock rotating disk;
Keeping device is placed on product;
Accomplish fluently light;
Bottom (transition zone), spraying temperature 1100 DEG C is combined by spray gun fast spraying;
Cooling more than 5min;
Spraying magnetic layer (1000 degree make tinsel granulate), distance and spraying rate regulation with spray gun to pot surface are led
The uniformity of magnetic film;
Cool down more than 1 hour;
With hardhead sponge polishing magnetic conductive film surface (making uniform good-looking attractive in appearance);
Outermost stopping off, spraying temperature 1200 DEG C;
Join lid pack (not hurting film with rigid article) warehouse-in.
Three, sampling observation electromagnetic oven is tested magnetic conduction effect and makes a record.
Four, success rate reaches more than 95%.
Five, total film thickness controls at 0.6-0.7 millimeter.
Six, transition zone, magnetic layer, the material of protective layer are consistent.
Seven, during spraying transition zone nozzle to pot surface distance 30 centimetres, when spraying magnetic layer nozzle to pot surface away from
From 40cm, during spraying protective layer, nozzle is to 50 centimetres of pot surface.
Eight, color and luster can show the thickness of film layer, and general light gray-white is preferable.
Nine, sampling examination is from the beginning of 1000 degree, can be raised to 2000 degree after 5 minutes.
It should be noted last that, above example is only in order to illustrate technical scheme and unrestricted, although ginseng
It is described in detail according to the embodiment of the present invention, it will be understood by those within the art that, to technical scheme
Modifying or equivalent, without departure from the spirit and scope of technical scheme, it all should contain the present invention's
