Description

A kind of method of pug preparation shadow-mark porcelain billet
Technical field
The present invention relates to ceramic fabrication technique field, in particular to a kind of method of pug preparation shadow-mark porcelain billet.
Background technique
In China, ceramics have very long history, various fields have nowadays been used in, especially in daily necessities In, ceramic is even more to be seen everywhere, and preparation process is also widely used in worldwide already, and ceramic ware for daily use is solemn So have become a part indispensable in people's daily life, panoramic tableware, tea set, decoration, all kinds of sanitary wares etc. with Place as it can be seen that these ceramics beautiful and generous, various shapes can also be prepared resistance to and according to the difference of its purposes mostly High temperature, abrasion-resistant, corrosion resistant ceramics, but with the development of people's demand and market, people are continuous to the function of ceramic It is proposed new requirement.
In order to meet the needs of market, the decorative effect of ceramic is improved, the ceramic with certain translucency can To generate the heat that penetrating and change effect has become major ceramics factory expert research and development under the action of light.Deeply by consumer Like traditional ceramic product translucency poor, affect its further popularizing in fields such as building decorations.
Currently, these formulas have not in terms of translucency there are also the formula that producer develops light-transmittance ceramics brick Mistake performance, but these formula have there are powder poor plasticities, blank forming difficulty and green strength are low, and some light-transmittance ceramics are matched Square alumina content is low to cause formula elevated temperature strength low, and green body is easily deformed in firing, and therefore, up to the present the country does not have The light-transmittance ceramics brick formula that ceramic producer is researched and developed using oneself is produced in batches.Patent No. CN105565668A is to disclose one Light-transmittance ceramics color glaze and its production method are planted, the ratio of rugged property raw material quartz, frit and feldspar is up to 90% in blank formulation More than, the usage amount of raw mineral materials inevitably enlarges, and cost also increases therewith.Therefore, this experiment is thought only to be made with a kind of pug Standby shadow-mark porcelain billet.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of pug preparation shadow-mark porcelain billets Method is handled by the classification to pug using a kind of pug as the primary raw material of porcelain billet, required non-magnetic raw material is obtained, with height Ridge soil carries out a certain proportion of mixing and obtains shadow-mark porcelain billet by some steps, and this method significantly reduces production cost, Environmental pollution is reduced, the good porcelain billet of light transmittance is obtained.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of method of pug preparation shadow-mark porcelain billet, includes the following steps；
(1) magnetic separation classification processing is carried out to pug, obtains two kinds of products: magnetic material and non-magnetic raw material；
(2) in mass ratio, 60~80% non-magnetic raw material, 20~40% kaolin, according to non-magnetic raw material and height are weighed The natrium carbonicum calcinatum of additive 0.5%, 0.8~1% sodium carboxymethylcellulose pyce, 0.3~0.5% poly are added based on the soil of ridge Sodium phosphate obtains mixing blank after mixing well；
(3) will mixing blank through wet ball grinding, ball mill ball milling carries out mist projection granulating after abundant ball milling, aging, obtains powder Material；
(4) resulting powder is placed in press and carries out half-dried compression moulding, obtain adobe, adobe is put into electric furnace by drying In, heat preservation, furnace cooling obtains shadow-mark porcelain billet.
The revolving speed of ball mill is adjusted to 300~350r/min in the step (3), and Ball-milling Time is 30~40min, expects: Ball: water 1:2:1, the fineness that blank is obtained after abundant ball milling is 250 mesh, and the sieve of sieving, less than 0.5%, is then sprayed in amount Mist is granulated, aging 12h.
Adobe thickness control is obtained in the step (4) in 6~7mm, adobe is fired to by dry be put into electric furnace 1250~1280 DEG C, keep the temperature 20~40min.
Beneficial effects of the present invention:
The present invention is handled with using pug for main raw material sources by classification, and non-magnetic raw material is obtained, and is added a certain amount of Kaolin at high temperature, successfully fires shadow-mark porcelain billet by green compact forming method.Because experiment in only used non-magnetic raw material and A small amount of kaolin, greatly reduces production cost, reduces environmental pollution, obtains the good porcelain billet of light transmittance.In addition, Preparation process of the present invention is simple, cost of material is low, broad application temperature range, can be widely used in household china, architectural ceramics and art Porcelain etc. has preferable commercial scale application prospect.
