Abstract
The invention discloses an enamel inner container of an electric pressure cooker and a manufacturing method thereof. The enamel inner container is characterized in that the inner container is a cylindrical metal matrix, the inside and the outside of the metal matrix are enamel coating, and an opening on the top of the inner container is provided with a re-cladding metal ring with a curled edge and a re-cladding metal ring with a straight edge. The enamel coating is fused and condensed on surface of the metal matrix. The metal matrix is made of a cold rolled plate, an aluminum plate or a stainless steel plate. The thickness of the enamel coating is 150-400 microns. The enamel inner container of the electric pressure cooker can be made by steps of preparing a blank, treating blank surface, preparing enamel slurry, wet-process enameling, drying and single firing or by twice-coating and twice firing. The wet-process enameling is realized by an enamel dipping method or an enamel spraying method. The blank surface treatment comprises degreasing, pickling, neutralizing and drying. The enamel inner container of the electric pressure cooker has the advantages of good heat storage effect, good rigidity, good pressure resistance, and good heat conductibility, corrosion and wear resistance, environmental protection, energy saving and being capable of cooking nutritious and delicious food and the like.
Description
Technical field
The present invention relates to the method for a kind of enamel inner container of electric pressure cooker and manufacturing enamel inner container of electric pressure cooker.
Background technology
At present, aluminum liner is generally made by technologies such as electrification, anodic oxidation, sprayings, when boiling soda acid salt food, particularly during basic food, very serious to the aluminum pot corrosion, add that coating is heat-resisting poor, not wear-resisting, come off easily, polluted food, long-term use causes serious harm to the health of human body.Stainless-steel pan, particularly boils when containing soda acid salt food when heating owing to contain heavy metal element such as chromium, and these heavy metal elements are dissolved on the food easily, and long-term use meeting causes serious harm to health.
Summary of the invention
The method that the purpose of this invention is to provide a kind of enamel inner container of electric pressure cooker and manufacturing enamel inner container of electric pressure cooker.
Purpose of the present invention is achieved through the following technical solutions.
A kind of enamel inner container of electric pressure cooker is characterized in that: described inner bag is the cylindrical metal matrix, and the inside and outside both sides of metallic matrix are enamel coating, and the opening part at inner bag top is provided with outer crimping and straight flange wraps two kinds of quoits again.
Described enamel coating fusion condenses on the surface of metallic matrix.
Described metallic matrix is made by cold-reduced sheet, aluminium sheet or corrosion resistant plate.
The thickness of described enamel coating is the 150-400 micron.
Described enamel inner container of electric pressure cooker makes by base, the surface treatment to base, preparation glaze slip, the wet method application of slip, drying, an once-firing.It is better also can to adopt two technologies that are coated with two burnings to make effect.
Described wet-process enamelling adopts and soaks the method for warding off or spray method.
Described surface treatment to base comprises green compact, degreasing, pickling, neutralization, drying.
The firing temperature of described once-firing is about 800-850 degree centigrade, and the duration is about 4-6 minute (is example with the cold-reduced sheet).
The present invention compared with prior art has the following advantages:
Enamel inner container of electric pressure cooker of the present invention is the high-tech product of the applicant's independent research success, it is effective that boccaro pot, watt pot etc. have heat accumulation on the existing Chinese traditional food of this inner bag, can cook delicious and nourishing food etc. advantage, also have the good rigidlies that metal pan had such as stainless steel, aluminum pot and pot possessing composite bottom, good heat conductivity, withstand voltage, anti-wear performance good, the positive effect of environmental protection and energy saving.Prepare glaze slip and corresponding processing step owing to adopt the vitreous enamel frit to mill through scientific matching, the function admirable of enamel inner container of the present invention, the life-span of inner bag obtains very big prolongation, and the enamel coating adhesion property can be up to state standards.The heat-resisting sudden turn of events of enamel layer and acid and alkali resistance, salt performance are good, meet the FDA food hygienic standard.In addition, the technology of making enamel inner container of the present invention is simple relatively, need not to purchase the required expensive device of electrostatic enamelling and easier being widely used reconstructed in the place.
Description of drawings
Fig. 1 is the structural representation of enamel inner container of electric pressure cooker of the present invention;
Fig. 2 is the local structure for amplifying schematic diagram of enamel inner container of electric pressure cooker wall of the present invention.
The specific embodiment
Describe in further detail below in conjunction with the method for accompanying drawing enamel inner container of electric pressure cooker of the present invention and manufacturing enamel inner container of electric pressure cooker.
As Fig. 1 and shown in Figure 2, enamel inner container of electric pressure cooker described in the utility model is an open-topped cylindrical inner bag 1, cylindrical wall is made up of metallic matrix and enamel coating 2, enamel coating is coated on the inside and outside both sides of metallic matrix, metallic matrix is made by cold-reduced sheet, aluminium sheet or corrosion resistant plate, and the upper opening of cylindrical inner bag is provided with outside circular crimping and straight flange wraps two kinds of quoits again.
The method of making enamel inner container of electric pressure cooker is as follows:
At first the steel plate process is cut out the blank that operations such as material, punching press, stretching are processed into enamel inner container of electric pressure cooker, handle on the surface to blank after the blank moulding, and its step is as follows:
Degreasing: about 5 minutes of the liquid mixture prepared groove immersions (employing hypercolour wave trough effect is better) such as degreasing acid sodium of blank being put into NaOH and the 5g/L of about 80 50g/L that spend.Put into the clear water rinsing of flowing again.
Pickling: normal temperature uses down 6% hydrochloric acid to clean the rusty stain on blank surface, and it is clean to put into the clear water rinsing of flowing again.
Neutralization:, again it was immersed in 1% the hot soda ash solution 5 minutes through the clean blank of rinsing.
Dry: as to make blank at room temperature dry.
Enamel inner container of electric pressure cooker of the present invention has that heat accumulation is effective, good rigidly, wear-resisting withstand voltage good, Outside the advantages such as good heat conductivity, antiseptic property are good, environmental protection and energy saving, can cook delicious and nourishing in addition The advantages such as food.
