Description
Technical field
The present invention relates to ceramic technology field, specifically a kind of production technology of pottery insulation utensil.
Background technology
Pottery is originated in the Eastern Han Dynasty, is one of five big kiln porcelain of Song Dynasty, the treasure in Han nationality's tradition technology in producing porcelain, is referred to as
National treasure, rarity, it is world-famous for the transmutation art of uniqueness, is known as " the valuable an ancient unit of weight of gold is priceless " and " there is ten thousand strings of cash in family, not as pottery
One " good reputation, be the exclusive national treasure porcelain in Countermeasure In Yuzhou City of Henan Province god Hou towns, by its simple and unsophisticated moulding, consummate technique, multiple
The miscellaneous change nothing such as magical transmutation, the beautiful scenery of lakes and mountains, rosy clouds fog, people's beast flower, bird, insect, and fish with glaze, " it is color to enter kiln kiln discharge ten thousand of the same colour "
Poor figure color and marvellous charm, it is described as first of Chinese " five big porcelain ".
China has the history with more than one thousand years using porcelain, and porcelain tool is the part that can not be lacked in common people's daily life,
The pottery device shape transformation in terms of household utensils, it is to use pottery or other porcelain just to have many daily apparatus at present
It is prepared, but with China's cultural life and the continuous improvement of material life, people are to family life articles for use and decoration material
The requirement more and more higher of the aesthetic property of material, quality, pattern, the function of traditional ceramic utensil can not meet the need of people
Ask, specific manifestation in the following areas, first, traditional pottery colour generation and the change of moulding far can not meet pottery fan
Requirement, color and luster is splendid not as metallic article, second, in terms of feature, people are not content with as just simple
Utensil uses, and there is insulation and the pottery product of purifying health care effect more will be favored by people, three be due to ceramic material itself
Limitation, the surface of obtained pottery product is easy to adsorb the impurity such as bacterium, dirt, not only influences attractive in appearance, nor is beneficial to
Clean environment and health.
Therefore, a kind of formula of production is excellent, and preparation method is simple, and burning process is unique, product design and quality reality attractive in appearance
With the pottery insulation utensil that integrated artistic flow easily manipulates, there are extensive market prospects.
The content of the invention
The invention aims to solve the deficiency of above-mentioned technical problem, the present invention proposes a kind of pottery insulation utensil

And practicality.
The present invention is for the insufficient technical scheme that uses for solving above-mentioned technical problem：A kind of life of pottery insulation utensil
Production. art, comprise the following steps：
（1）The blank and glaze of pottery are chosen, the glaze is the glaze with antiseepage and health-care effect；
（2）Above-mentioned blank and glaze are put into ball mill and carry out grinding；
（3）Use step（2）In blank prepare the base substrate of sandwich, and the preformed hole that vacuumizes is set in the outer layer of base substrate,
The preparation method of described base substrate includes any one in the throwing method of forming, slip casting or the method for forming of moulding adobe blocks；
（4）Use step（2）In blank prepare seal bar, the diameter of the seal bar is more than the aperture of the preformed hole, described
The length of seal bar is identical with the thickness of the outer wall of the base substrate interlayer；
（5）By step（3）Obtained base substrate and step（4）Obtained seal bar, which is put into vacuum sintering furnace, tentatively to be sintered,
Oxidation operation, moisture effusion in sintering process in base substrate and seal bar, base substrate and seal bar are shunk, after the completion of sintering
Cool to room temperature with the furnace, take out standby；
（6）To step（5）On the inner and outer wall of base substrate after the completion of the preliminary sintering and surface of seal bar applies and had
Antiseepage and the glaze of health-care effect, then seal bar is filled in the preformed hole of base substrate, be put into vacuum sintering furnace and sinter again,
Opening vavuum pump takes the air in the interlayer of base substrate away in sintering process, and controls the temperature in sintering furnace under vacuum
It is sintered, melts the glaze in seal bar and interlayer, and the sealing completed to the preformed hole of base substrate is flowed in billet surface,
Cool to room temperature after the completion of to be sintered with the furnace, take out standby；
（7）The outer wall of ceramic thermal insulation utensil to being densified after glaze firing cleans, and metal-coated films on the outer wall；
（8）One layer is coated with the surface of the ceramic thermal insulation utensil of metal-coated films to be made up of sol and titanium dioxide anti-bacterial agent
Sol pellicle, form antimicrobial nano coating on the surface of ceramic thermal insulation utensil after sintering, you can be made with metallic luster and
The pottery insulation utensil of antibacterial action；
（9）To step（8）Obtained ceramic thermal insulation utensil carries out vacuum-tightness detection and heat-insulating property detection, and rejects and do not conform to
Lattice product.

The present invention is to provide a kind of production technology of pottery insulation utensil, can solve traditional pottery with steam vent and protect
Warm utensil is in the defects of aesthetic measure and integral heat insulation effect.Traditional pottery insulation utensil all carries steam vent, and reason is
During firing, the temperature of high-temperature fusion formation, blank and glaze when inevitably needing steam vent to discharge firing
Material caused internal high temperature gas during high-temperature fusion, if discharged without steam vent, will result in pottery utensil
Burst, cause product to fire, but the utensil with steam vent is again deficient on aesthetic measure and integral heat insulation effect
Lack, and the steam vent of later stage closing should be doubly cautious during use after processing seals, avoid touching, otherwise just lose
The effect of insulation, causes the product can not to use；The technique of the present invention, the base substrate of sandwich is first prepared, and in the outer layer of base substrate
The preformed hole that vacuumizes is set, the material as base substrate is reused and prepares the seal bar to match with preformed hole, base substrate and
Seal bar is first tentatively sintered, and is discharged blank caused internal high temperature gas during high-temperature fusion, is avoided causing pottery
Utensil is burst；Then again on the inner and outer wall of the base substrate after the completion of preliminary sintering and the surface of seal bar applies tool
There is the glaze of antiseepage and health-care effect, and seal bar filled in the preformed hole of base substrate, be put into vacuum sintering furnace and sinter again,
Opening vavuum pump takes the air in the interlayer of base substrate away in sintering process, and controls the temperature in sintering furnace under vacuum
It is sintered, melts the glaze in seal bar and interlayer, flows, both realized at the finish to billet surface in billet surface
Reason, the sealing function between seal bar and base substrate is realized again, improve the heat insulation effect of pottery utensil；It is in addition, provided by the invention
It is a kind of production technology of pottery insulation utensil, also to metal-coated films on the outer wall for the ceramic thermal insulation utensil being densified after glaze firing
With antimicrobial nano coating, obtained insulation utensil is set to have the texture of ceramics and distinctive metal color, bright in luster, glossiness concurrently
It is high, corrosion-resistant, wearability is good, it is easy to clean to be not easy to attach dirt, sterilization again, has sight and practicality concurrently.
