Description
Technical field
The invention belongs to ceramic utensil field, the specifically a kind of and preparation side of the matching used ceramic inner vessel of electric food warmer
Method.
Background technology
Electric food warmer is a kind of electric-heating cooking utensil.Metal heat generating member in electric food warmer through heating power, heat transfer to heating
The interior pot that part fits, and internally the food in pot boils.At present, the frequent pot in supporting pottery of electric food warmer, makes food cooking
Adjust relatively sanitary and delicious.
The heat generating member of conventional electric food warmer and ceramic pot bottom contact portion are a planes（Or the plane of dimpling）, ceramic pan
Heat be from the bottom of a pan import.During boiling, if the moisture of food is reduced in pot, food is heated in pot, occurs
Uneven, the effect that boils can decline（As cooking rice is also easy to produce half-cooked phenomenon）.Household electrical appliances manufacturing is entered to electric food warmer heat generating member
After row transformation, the external form of heat generating member is improved to dish-type or bowl-type from plane, heat transfer form is conducted heat from the pot bottom of routine and improves
Conducted heat simultaneously for pot bottom and pot wall, improve the effect that boils.
Electric heating element with radian is at work, it is desirable to ceramic outer wall of wall good fit, could effectively carry out heat
Conduction.This requires the profile of ceramic pan and regularity must reach the strict demand of design, some conventional permissions of ceramic pan
Scale error scope diminish, the pot wall thickness requirement of ceramic pan also changes, and the glaze layer of ceramic pan should reach flat smooth,
These particular/special requirements, cause conventional ceramic pan preparation method can not meet the requirement of this Special-purpose ceramic cooker.Therefore, it is necessary to make
It is standby to go out to meet the ceramic pan of this particular/special requirement.The problem is classified as innovation subject by household electrical appliances and ceramic industry, from ceramic raw material
It is combined in terms of innovation and improvement that formula, die treatment, formed product, product are burnt till etc., captures production technology difficulty,
Problem be present in solution.
The content of the invention
It is an object of the invention to provide a kind of ceramic inner vessel qualification rate is high, regularity is high, glaze layer flat smooth, the bottom of a pan and
Pot wall and electric food warmer arc heat generating member good fit, the preparation side with the matching used ceramic inner vessel of electric food warmer of good heat conduction effect
Method.
The preparation method with the matching used ceramic inner vessel of electric food warmer of the present invention, it is characterised in that including following production
Step：
（1）It is prepared by blank
Take kaolin 20-24 parts by weight, spodumene 16-20 parts by weight, petalite 30-34 parts by weight, talcum 4-8 parts by weight,
Clay 10-14 parts by weight, bentonite 1-3 parts by weight, waste ceramic 6-10 parts by weight are as blank stock.
Above-mentioned waste ceramic is scrap caused by ceramic pan production process, and these scraps are scrapped afterwards through burning till,
It is a kind of crystalline material by firing, waste ceramic fragmentates through impact, then can be used after being rolled into sand shape thing.
After above-mentioned raw materials are mixed plus clear water carries out wet ball grinding, and 220 mesh sieves are crossed through ball milling raw material, and through sieving, raw material passes through
Filter press press filtration is deposited in through press filtration clod and old 48-60h is carried out in wet environment, pass through pugging through old clod into clod
Machine carries out continuous pugging three times, and the blank for preparing mass moisture content 21%-23% is standby.
The special role of raw material and blank preparation technology in the above-mentioned formula of brief description：Waste ceramic is added in formula, for
Reduce shrink of product rate, improve product regularity, it is beneficial to reduce the volatile matter generation of sintering process product etc.；Formula
In use two kinds of lithium-containing materials of spodumene and petalite simultaneously, can make that product thermal shock resistance is stable, the decline of product deformation rate.
Clay and bentonite are used in formula, is the plasticity for adjusting blank, product is not ftractureed in forming process.Blank system
In standby, carry out continuous pugging three times again after the old 48-60 h of press filtration clod, be make the viscosity of blank and plasticity reach product into
The requirement of type.
（2）It is prepared by glaze
Take kaolin 9-11 parts by weight, spodumene 50-58 parts by weight, petalite 14-18 parts by weight, magnesia 11-13 weight
Part, raw material of the calcium oxide 7-9 parts by weight as glaze.
After above-mentioned raw materials are mixed plus clear water carries out wet ball grinding, through ball milling raw material by magnetic separator de-ironing iron removaling, after iron removaling
Raw material crosses 320 mesh sieves, adds clear water to be deployed into the glaze that concentration is 48 Baume degrees through the raw material that sieves standby.
（3）Product roll forming
Product molding uses the roll forming lathe and gypsum mold of household porcelain production, using above-mentioned standby blank, adopts
Use flow forming process.
Cleaning treatment is carried out to gypsum mold before production, discarded using tea head caused by the finished tea manufacturing process of Feng huangshan Mountain
Material progress is soaked, and tea head dead meal 1kg adds 80-90 DEG C of clear water 100kg, after soaking 1 h, takes Aqua Folium Camelliae sinensis in gypsum mold
Chamber is cleaned, and removes the residue on surface, and cleaned gypsum mold places 10- in the hothouse that temperature is 50-60 DEG C
12 h, decline gypsum mold moisture content, water absorption rate improves, thicker suitable for bottom and wall, and the special pottery that pot wall band is cambered
The roll forming of porcelain pot.
In product molding, every product roll forming time is 22-28s, and relatively conventional rolling extended for 1/3 time,
The shale density and regularity for ensuring product unpainted clay idol improve.
（4）Product repaired biscuit
The unnecessary pug of moulded products opening is removed using the cutting of small steel knife, moulded products surface is carried out using clear water and cotton
Cleaning, makes product surface flat smooth.
（5）Product glazing
Using above-mentioned standby glaze, glazing is carried out to product using immersion glaze mode by hand.
（6）Product is burnt till
Using Production of Ceramics kiln, to being burnt till through slipware, firing atmosphere is oxidizing atmosphere, burns till maximum temperature and is
1280-1290℃；Firing time is 14-16h, and in sintering process, kiln temperature should keep 1.5- 1220-1230 DEG C of stage
2h, product carcass is set to be well combined with surface glaze layer, glaze layer flat smooth, glaze layer compactness improves, and after the completion of burning till, is made one
Kind and the matching used ceramic inner vessel of electric food warmer.
After the above method, the present invention has the beneficial effect that：
Obtained ceramic inner vessel qualification rate is high, and regularity is high, glaze layer flat smooth, the bottom of a pan and pot wall and electric food warmer arc heat generating member
Good fit, good heat conduction effect, it is delicious to be cooked food, rice without it is half-cooked phenomena such as.
