Abstract

The present invention relates to a low-temperature fast firing technology of household fine porcelain, which belongs to the field of household porcelain. The technology comprises: blank material, glaze material and a firing method thereof. In the technology, 10 to 30% of albite or 1 to 4% of alkali earth metal mineral are introduced into the blank material, and the main chemical components of the blank material comprise the material of the following proportion by weight: 62.0 to 65.0 wt% of SiO2, 20.0 to 25.0 wt% of Al2O3, at most 0.4 wt% of Fe2O3, 0.2 to 2.0 wt% of CaO, 0.2 to 1.0 wt% of MgO, 0.4 to 3.4 wt% of Na2O, 3.0 to 6.0 wt% of K2O and 4.0 to 6.0 wt% of IL; the glaze material adopts the raw glaze material of a compounding fusing agent, and the chemical components of the glaze material comprise the material of the following proportion by weight: 62.0 to 65.0 wt% of SiO2, 10.0 to 14.0 wt% of Al2O3, 8.0 to 10.0 wt% of CaO, 1.0 to 3.0 wt% of MgO, 2.0 to 6.0 wt% of ZnO, 1.0 to 4.0 wt% of Na2O, 4.0 to 6.0 wt% of K2O and 1.0 to 3.0 wt% of F; the blank material and the glaze material are fired with a roller kiln by a one-step firing process, the firing temperature is controlled at 1200 to 1250 DEG C, and the firing period is from 70 to 120 minutes. Compared with the existing firing temperature, the firing temperature of the technology is reduced by more than 100DEGC, the firing period is shortened by 2/3 of that of the existing firing period, and the energy saving and consumption reducing effect is obvious.

Description

Low temperature rapid sintering process of domestic fine pottery
The invention provides the new production method of a kind of daily-use fine, belong to the domestic ceramics field.
The firing temperature of daily-use fine is 1320~1380 ℃ at present, and firing period is more than 8 hours, and what have reaches 24 hours.The consumption of fuel and kiln furnitures is big, has also shortened simultaneously the work-ing life of kiln, makes that to burn till cost high, and environment is brought disadvantageous effect.Therefore, no matter from economy or environmental angle, adopting low temperature fast firing energy-saving and cost-reducing is the development trend of daily-use fine.
The object of the present invention is to provide the new production method of a kind of daily-use fine, reduce firing temperature significantly, shorten firing time.Quality product meets the requirement of GB/T3532-1995 " daily-use fine " national standard simultaneously.
The present invention includes blank, glaze formula and process for calcining
1, blank: adopt and introduce 10-30% albite or 1-4% mineralizer (comprising talcum, phosphatic rock etc.), control quartzy mineral content, improve measures such as blank fineness, improve the speed of response of blank, reduce the destruction that the residual quartz crystal conversion brings at sintering process.Guarantee that when low temperature fast firing, each component is fully reacted fusion, form fine and close fine and smooth porcelain, avoid porcelain base quenching process to burst.
The main chemical constitution (Wt%) of blank is: SiO 262.0~65.0 Al 2O 320.0~25.0 Fe 2O 3≤ 0.4 CaO 0.2~2.0 MgO 0.2~1.0 Na 2O 0.4~3.4K 2O 3.0~6.0 IL 4.0~6.0 blank fineness: 320 mesh screen residues≤0.2%
2, glaze: adopt raw glaze by composite fluxing agent is adjusted proportioning, make it existing higher initial melting temperature, have the good high-temperature flowability again, guaranteeing has good glaze quality under the low temperature fast firing condition, and with low cost.
The main chemical constitution (Wt%) of glaze is: SiO 260.0~65.0 Al 2O 310.0~14.0 CaO 8.0~10.0MgO 1.0~3.0 ZnO 2.0~6.0 Na 2O 1.0~4.0K 2O 4.0~6.0 F 1.0~3.0
3, burn till employing roller kiln once-firing, 1200~1250 ℃ of firing periods of firing temperature: 70~120 minutes.
4, other production technique is identical with existing daily-use fine production technique.
Production method of the present invention is:
Picking of raw material, elutriation → batching → grinding → deironing → press filtration → pugging → moulding → glazing → roller kiln burn till → finished product
The present invention has compared following characteristics with existing daily-use fine production technique:
1. firing temperature reduces more than 100 ℃;
2. firing period is existing below 1/4 of technology;
3. kiln furnitures consumption and manning reduce than existing technology.With short production cycle, fast to market response.Example blank 1. potassium felspar sand is washed mud 50%, and albite is washed mud 30%, kaolin 20% chemical constitution (Wt%):
IL SiO 2 Al 2O 3 Fe 2O 3 CaO MgO Na 2O K 2O

Above-mentioned base glaze is produced by daily fine porcelain production technique, burns till in 120 minutes with 1230 ℃ at 30 meters roller kiln, and product meets GB/T3532-1995 " domestic porcelain " national standard.
