Abstract
The invention discloses a zirconia coating layer for a saggar; the zirconia coating layer includes the following components in parts by mass: 4-6 parts of 60-mesh fused zirconia, 1-4 parts of 100-mesh fused zirconia, 1-3 parts of 200-mesh fused zirconia, 0.1-0.5 part of sodium hexametaphosphate, 0.1-0.5 part of polyvinyl alcohol, and 1-5 parts of water. At the same time, the invention also discloses a preparation method of the zirconia coating layer saggar. The product has the advantages of low cost, stable quality and long service life, and is more convenient to use than a traditional product.
Description
Technical field
The invention belongs to fire resisting material field is and in particular to a kind of zirconia coating for saggar and this saggar
Preparation method.
Background technology
The firing temperature of ferrum oxygen soft magnet material typically between 1100 DEG C to 1450 DEG C, for preventing product to be scattered,
Burning till of ferrum oxygen soft magnetic bodies typically uses mullite saggar as carrier, but the ferrum in ferrum oxygen soft magnetic bodies, nickel,
Aluminium oxide easily and in saggar material for the compositions such as manganese, oxidation pasc reaction, cause contamination of products, damage product
Performance.Most manufacturers take in saggar one layer of 4mm of pad about thick zirconium oxide plate (zirconium oxide and ferrum oxygen
Soft magnetic bodies Fails To Respond) or uniformly spread last layer zirconium oxide sand, the contact with mullite sagger for the insulation product.
With the restriction of technology development and market condition, using zirconium oxide backing plate and spread zirconium oxide husky the drawbacks of increasingly
Prominent.Main performance the following aspects.1st, use zirconium oxide backing plate：(1) price of zirconium oxide backing plate is high.
Standard oxidation zirconium plate (100 × 100 × 4mm), univalent 9-12 unit, equivalent 900-1200 unit/M2.(2) make
Low with the life-span.Because thermal shock resistance is poor, averagely every piece life-span is less than 2 months.2nd, using oxidation zircon sand：
(1) oxidation zircon sand is easily corroded by the mullite of saggar base material, with changing after a while, produces into
This height.(2) oxidation zircon sand is not easy uniform fold base plate, the ferrum oxygen soft magnetic bodies vulnerable to pollution of exposed part.
Content of the invention
Goal of the invention：Present invention aims to the deficiencies in the prior art, provide a kind of oxygen for saggar
Change zirconium coating.
Another object of the present invention is to providing the preparation method of above-mentioned zirconia coating saggar.
Technical scheme：In order to achieve the above object, the present invention is specifically achieved like this：One kind is used for saggar
Zirconia coating, including the component of following mass fraction：60 4～6 parts of mesh electric-melting zirconias, 100 mesh electric smelting
1～4 part of zirconium oxide, 200 1～3 part of mesh electric-melting zirconias, 0.1～0.5 part of sodium hexameta phosphate, polyvinyl alcohol
0.1～0.5 part, 1～5 part of water.
A kind of preparation method of zirconia coating saggar, comprises the following steps：
(1) 60 mesh electric-melting zirconias of 4～6 parts of mass fraction are weighed, 1～4 part of 100 mesh electric-melting zirconias,
1～3 part of 200 mesh electric-melting zirconias, 0.1～0.5 part of sodium hexameta phosphate, 0.1～0.5 part of polyvinyl alcohol,
With 1～5 part of water；
(2) compound is put into blender, mixed 1～2 hour with 120 revs/min of rotating speed；
(3) with hairbrush, the material mullite sagger inner surface sintering is applied one layer of compound, or mixed
Close material and pour saggar into, vibrate saggar, be allowed to even application in saggar inner surface；
(4) saggar handled well standing nature is dried 12～24 hours, put into drying room through 110 DEG C, 24～36
Hour is dried；
(5) saggar is put into high temperature kiln through 1550 DEG C, burn till within 3～4 hours；
(6) after saggar kiln, standing cooling, the selection warehouse-in to room temperature.
Beneficial effect：The present invention, compared with conventional art, has the advantage that：
1st, cost is relatively low, and every square metre of materials of zirconia coating are only and use 1/5th of zirconium plate；
2nd, steady quality, life-span are high, and the service life of zirconia coating is synchronous with saggar, significantly larger than zirconium plate
And zircon sand；
3rd, link easy to use, decreasing pad zirconium oxide plate and spread oxidation zircon sand, using more convenient.
