Description
Technical field
The present invention relates to heating kettle technical field, in particular to a kind of metallic object and heat-generating disc suitable for food container.
Background technique
Kettle is the necessity of life, from coal gas kettle to intelligent plastic electric heating kettle, arrives stainless steel insulating pot, then to partly
Glass water pot, full glass water pot, product are being kept updating.It is glass physical stability of characteristics, safety, clean, it will not be with heating
Food generate chemical reaction, do not have the secret worry of heavy metal, the transparent body of glass can penetrate far infrared, promoted water quality,
Optimize water source.
Current full glass water pot substantially has technologies several in this way: transparent nano film, carbon film and thick film.The first two kind power declines
Subtract fastly, abandoned by various manufacturers, the latter's power stability is good, but technique requires height, wants to the processing index of glass body
Ask stringent, such as: smoothness, the uniformity of thickness, compactness cannot have bubble, hollow etc..In These parameters, any one
Standard is not achieved, Electric radiant Heating Film is also easy to produce hot knot and micro- sudden strain of a muscle electric discharge, and instantaneous temperature is high, and it is broken to eventually lead to vitreum.Moreover, hair
Hotting mask needs temperature characterisitic, the matched coefficients of thermal expansion with glass, while good can also adhere to, infiltrate with glass.And
It also to fire and test after the slurry modulation of heating film, test period is long, and uncertain factor is big, once the physical property variation of glass is again
The long period is spent to re-modulate.
With current glass industry level of processing both domestic and external, it is unable to satisfy above-mentioned processing index.Then at high cost
High quartz glass comes into being to substitute the solution of the Pyrex of good economy performance.However, the cost of quartz glass is
Tens times of Pyrex, although the thickness of quartz, flatness, bubble hollow are superior to borosilicate, quartzy fusing point is high, kettle body at
Type difficult processing, cost is huge, is unable to volume production.
In order to solve the inherent shortcoming of glass material, occur other some solutions these years, such as: cut bottom glass
Glass kettle body uses ceramic heating plate/crystallite heating plate and silica gel sealing ring, is embedded in and cuts in the glass pot body of bottom, form one kind
Pseudo- full glass health-promotion kettle.It is directly contacted with heating liquid due to metal heating tray, although heat transfer efficiency can be improved, it is broken
It is broken all-glass theory, during hot cooking food, food and silica gel are chemically reacted, and cause pollution, discoloration, heavy metal super
Mark.Moreover, the place of sealing ring and heater transition is usually also the dead angle of cleaning, it cannot be guaranteed that safety and sanitation.In addition, above-mentioned
The sealing consistency of structure is bad, can not achieve volume production.
For another example: heating film is attached directly in kettle body, since kettle body material conducts heat is bad, be easy to cause hot-spot,
So that heating film overheats and ablation, it is also possible to cause kettle body to rupture because kettle body material cold-heat shrinks unevenness.
For another example: the scheme of external radiation places quartz heating-pipe in glass pot bottom, to being filled with water, glass container adds
Heat, the disadvantage is that: bottom heat is high, it is seen that polished bard eye, control system inaccuracy etc..
That is, the scheme of current full glass water pot can not meet simultaneously, cost is relatively low, the service life is long, safety, can volume production, cleaning
The problems such as being easy.

2, compactness is good: the coating can completely cut off completely metal surface and air, high-temperature heating when, guarantee metal not by
Oxidation；The coating has good insulating properties simultaneously, when being used for electric heating plate, can charge to avoid surface, meet electrical safety
Needs；
3, chemical stability is good: the coating substantially belongs to crystallite-glass mixture, and chemical property is stablized, for adding
When warm-served food product (< 400 DEG C), element-free is precipitated, and acid-proof alkaline is good, can meet the needs of food safety with direct food contact；
The coating is bright and clean, smooth, and it is easy to clean to encounter greasy dirt；
4, specific far infrared radiation feature: in 50~200 DEG C of temperature ranges, infra-red radiation of the coating at 9~15 μm
Wave band emissivity > 0.8, the radiation wave band are also the infra-red radiation fluctuation of water and human body simultaneously, are accordingly used in heating water or food,
There is health-care effect to human body.
Therefore, the glass function coating is fine and close, bright and clean, smooth, hard, chemical property is stable, it is made to be applied to production
When full glass water pot, can solve simultaneously cost is relatively low, the service life is long, safety, can volume production, cleaning the problems such as being easy.Specifically, this hair
When the bright metallic object for being formed with glass function coating is for making full glass heating container, it is used as heated base, from source
Solve the problems, such as that glass thermal coefficient is extremely low, to realize high-power, which can be in 800-3000
Watt area, which is arbitrarily set, matches.Moreover, the metallic object that the present invention is formed with glass function coating has excellent thermal conductivity, heat-generating disc
Operating temperature is only at 109 degree or so, so that the stability of heat-generating disc, reliability, life cycle be made to greatly improve.
Further, the metallic object is made by following methods:
Metal body surface is pre-processed, keeps its bright and clean, smooth；
By the way of spraying or printing, coating is uniformly coated on metal body surface；
The metallic object for being coated with coating is sintered at 600~1000 DEG C, is formed on the surface of metallic object fine and close, bright and clean, flat
The glass function coating whole, hard, chemical property is stable.
Correspondingly, being coated with glass on the heat-generating disc invention additionally discloses a kind of heat-generating disc suitable for food container
Powder coating, the glass powder coating can form glass function coating in fever panel surface；Wherein, the glass powder coating mainly by
50~90wt% glass powder and 10~50wt% organic component composition；The glass powder includes the glass powder of 17~100wt%
