Embodiment 1

[0029] Pretreatment: Pretreatment and processing of the waste liquid produced during the production of aluminum profiles; Neutralization: Use a metering pump to absorb the preparation solution and lye respectively, and stir slowly at the neutralization temperature to make the insoluble aluminum hydroxide produced Change from small particles or colloidal state to large particles, release surface adsorbates at the same time, and then separate; discharge: after the waste water is discharged up to the standard, the insoluble aluminum hydroxide sludge can be recycled to obtain aluminum hydroxide; preparation: the preparation Quartz, kaolin, and potassium feldspar used in ceramics are sorted, coarsely crushed, and weighed separately; billet making: each raw material after weighing is mixed, coarsely ground, 120-mesh sieved, pulped, wet ball milled, and sieved , press filtration, rough scouring, aging, and scouring to make finished mud; catalysis: adding appropriate aluminum hydroxide...

Embodiment 2

[0031] In embodiment one, add following operation:

[0032] In step 1, the pretreatment of acidic wastewater containing aluminum ions refers to the fine filtration of acidic wastewater containing aluminum to remove the suspended solids in it to obtain clear and transparent acidic wastewater containing aluminum, and then add The neutralizing agent is prepared, and the neutralizing agent is a soluble alkali, and the pH value is controlled to be 2-4 during preparation.

[0033] Pretreatment: Pretreatment and processing of the waste liquid produced during the production of aluminum profiles; Neutralization: Use a metering pump to absorb the preparation solution and lye respectively, and stir slowly at the neutralization temperature to make the insoluble aluminum hydroxide produced Change from small particles or colloidal state to large particles, release surface adsorbates at the same time, and then separate; discharge: after the waste water is discharged up to the standard, the i...

Embodiment 3

[0035] In embodiment two, add following operation:

[0036] Refers to adding the aluminum material taken out of the alkaline cleaning waste liquid into the pickling waste liquid, soaking for 2 hours to 48 hours, so that the ferric iron in it is completely reduced to ferrous iron, and the flocs are removed by filtration, and the flocs are removed. The substance is added to the untreated waste lye, and the filtrate is a clear solution containing acid and aluminum ions.

[0037] Pretreatment: Pretreatment and processing of the waste liquid produced during the production of aluminum profiles; Neutralization: Use a metering pump to absorb the preparation solution and lye respectively, and stir slowly at the neutralization temperature to make the insoluble aluminum hydroxide produced Change from small particles or colloidal state to large particles, release surface adsorbates at the same time, and then separate; discharge: after the waste water is discharged up to the standard, the ...

Abstract

The invention discloses a method for preparing environment-friendly domestic ceramics from aluminum hydroxide extracted from aluminum profile waste liquor. The method comprises the following steps: pretreatment: pretreating waste liquor generated during aluminum profile production. Aluminum hydroxide extracted from the aluminum profile waste liquor is used as a catalyst, and the problems that in the prior art, the manufacturing cost of the prepared high-brightness domestic ceramics is relatively expensive and the prepared domestic ceramics contains certain radioactive materials which can causecertain harm to the body of a user are solved; the method for preparing the environment-friendly domestic ceramics from aluminum hydroxide extracted from the aluminum profile waste liquor has the advantage of improving whiteness of the ceramics, original zirconium silicate is replaced with aluminum hydroxide, a radioactive composite is not contained, the cost is lower than that of ceramic blank containing zirconium silicate, about 1 / 3 of raw material cost is reduced, and whiteness also meets the requirement of whiteness of the ceramic blank containing zirconium silicate.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a method for preparing environment-friendly daily-use ceramics by extracting aluminum hydroxide from waste liquid of aluminum profiles. Background technique [0002] Ceramics are materials and various products made of clay as the main raw material and various natural minerals through crushing, mixing, molding and calcination. People make a kind of pottery clay and fire it in a special kiln at high temperature. Ceramics , ceramics is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. Bowls, etc. The production process of ceramic products refers to the whole process from the input of raw materials to the production of ceramic products. It is the laborers who use certain labor tools and follow certain methods and steps to direc...
