Abstract
The invention discloses a kind of preparation methods of low temperature domestic ceramics, the raw material of the household ceramic blank by picking of raw material, crushing, ingredient, dry powder ball milling, addition nanofiber additive, fineness test, size mixing, blowing, cross and screen out iron, filters pressing press filt, pugging, no longer need to through aging process, then after straight forming, drying process, through 8 hours, biscuiting is to 1100 DEG C, 30min is kept the temperature, obtains domestic ceramics element tire after cooling.The disadvantage that this method solve the tyre body hardness of Conventional cryogenic domestic ceramics is poor, thermal stability is poor.And its production method is scientific and reasonable, and technology is advanced, easy to implement, high yield rate, good product quality, and firing period can be greatly shortened, reduce firing temperature, significantly reduces production cost, therefore have a vast market foreground.
Description
Technical field
The invention belongs to inorganic non-metallic material (ceramics) fields, and in particular to a kind of preparation method of low temperature domestic ceramics.
Background technique
Domestic ceramics is always various countries noble porcelain for a long time, is the high-grade porcelain kind generally acknowledged in the world at present.Because it is " thin
Such as paper, thoroughly such as mirror, sound such as single sonorous stone, white as a jade ", porcelain exquisiteness is penetrating, and type is beautiful elegant, the moist light in color face, and flower face is colourful more
Color feature, has achieved its pure white quality and luxurious moulding, has concurrently using the dual value with art, is imperial palace in history
The treasure of special product and noble's collection is power and status symbol, is known as " king of porcelain ".Domestic ceramics with its high quality,
High style, high-grade use porcelain as major star hotel, general merchandise supermarket, the essential of powerful and wealthy family, and even more presenting friends is best
Gift.But the shortcomings that daily-use fine also has him compared with traditional pate dure, first is that tyre body hardness is relatively poor, product long-term
Porcelain mouth is easy production notch when use；Second is that thermal stability is relatively poor, suddenly cold and hot is in use, product is easy to happen bursts.
Therefore research invent it is a kind of have the advantages that domestic ceramics, and the domestic ceramics that tyre body hardness is big, thermal stability is good just have it is non-
Often big realistic meaning.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of green low-carbon, that product hardness is high, thermal stability is good is low
The preparation method of warm domestic ceramics.
The present invention is achieved by the following technical programs: a kind of preparation method of low temperature domestic ceramics, it is characterised in that:
The raw material of the household ceramic blank is by picking of raw material, crushing, ingredient, dry powder ball milling, addition nanofiber additive, fineness inspection
It surveys, size mixing, blowing, screen out iron excessively, filters pressing press filt, pugging, no longer need to through aging process, then after straight forming, drying process,
Through 8 hours, biscuiting kept the temperature 30min, obtains domestic ceramics element tire after cooling to 1100 DEG C.
The mass percent of the household ceramic blank raw material composition are as follows: apatite 50 ~ 55%, kaolin 20 ~ 30%, feldspar
10 ~ 20%, quartz 5 ~ 15%, additional nanofiber additive 5 ~ 10%.
The nanofiber additive is calcium phosphate nano fiber.
The time of the dry powder ball milling process is 18 hours.
The fineness test formed 250 meshes, and tailing over is 0.08%.
The molding procedure uses compression moulding.
The temperature of the drying process is 45 DEG C.
The present invention by adding calcium phosphate nano fiber, the netted package knot formed in green body using it in the feed
Structure can not only increase the plasticity of green body and the whiteness and thermal stability of intensity and carcass, it is daily to solve Conventional cryogenic
The disadvantage that the tyre body hardness of ceramics is poor, thermal stability is poor.And its production method is scientific and reasonable, and technology is advanced, easily
In implementation, high yield rate, good product quality, and firing period can be greatly shortened, reduce firing temperature, significantly reduce
Production cost, therefore have a vast market foreground.
Specific embodiment
For further illustrate the present invention, to reach the technical means and efficacy that predetermined goal of the invention is taken, tie below
Preferred embodiment is closed, the present invention is described in detail:
Embodiment 1
(1) mass percent ingredient: apatite 54%, kaolin 22%, feldspar is formed according to low temperature household ceramic blank raw material
14%, quartzy 10%, additional calcium phosphate nano fiber 6%；
(2) picking of raw material, crushing, ingredient are pressed, dry powder ball milling, fineness test, is sized mixing, blowing, mistake at addition calcium phosphate nano fiber
It is spare to screen out iron, filters pressing press filt, pugging, wherein the time of dry powder ball milling process is 18 hours, and fineness test formed 250 mesh
Sieve, tailing over is 0.08%；
(3) by the good green body of roll forming after 45 DEG C dry, through 8 hours, biscuiting kept the temperature 30min, natural cooling to 1100 DEG C
To room temperature kiln discharge, low temperature domestic ceramics element tire is obtained.
Embodiment 2
(1) mass percent ingredient: apatite 50%, kaolin 28%, feldspar is formed according to low temperature household ceramic blank raw material
16%, quartzy 6%, additional calcium phosphate nano fiber 7%；；
(2) picking of raw material, crushing, ingredient are pressed, dry powder ball milling, fineness test, is sized mixing, blowing, mistake at addition calcium phosphate nano fiber
It is spare to screen out iron, filters pressing press filt, pugging, wherein the time of dry powder ball milling process is 18 hours, and fineness test formed 250 mesh
Sieve, tailing over is 0.08%；
(3) by the good green body of roll forming after 45 DEG C dry, through 8 hours, biscuiting kept the temperature 30min, natural cooling to 1100 DEG C
To room temperature kiln discharge, low temperature domestic ceramics element tire is obtained.
