Description
Technical Field
The invention belongs to the technical field of refractory material production, and particularly relates to a preparation process of an adhesive for a casting mold and a sand mold plate combination of a casting alpha beta-corundum brick.
Background
The alpha beta corundum brick is applied to a glass kiln for producing high-quality glass in a masonry mode. The sand mould for casting alpha beta-corundum brick is made up by using white corundum and water glass according to a certain mixing ratio, then mixing them and making them into white corundum sand plate, then drying and drying them in drying kiln, after the white corundum sand plate is taken out of the kiln, it has need of using adhesive to adhere them together, and when they are combined, it has need of using adhesive to adhere them together. Therefore, there is a need for improved development and design of adhesives.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a preparation process of an adhesive for a casting mold and a sand mold plate combination of a casting alpha beta-corundum brick, which has the advantages of low cost, strong viscosity, high temperature resistance, unchanged property at high temperature and no pollution to sand molds and bricks.
In order to solve the technical problems, the invention adopts the following technical scheme: the preparation process of the adhesive for the casting mold and sand mold plate combination of the casting alpha beta-corundum brick comprises the following steps:
(1) carrying out Liwater on wet alpha beta brick grinding powder, and then airing and drying in the shade;
(2) screening the alpha beta grinding brick powder when the external moisture content reaches 2% -5%, and collecting the screened alpha beta grinding brick dry powder for later use;
(3) preparing alpha beta abrasive brick dry powder and water glass according to a certain proportion, and fully stirring to obtain a novel combined adhesive; transferring into a container for containing.
And (3) adopting a vibrating screen for screening in the step (2), wherein the screen mesh number of the vibrating screen is 250-300 meshes.
The stirring step in step (3) was performed in a B30C stirrer.
The Baume degree of the water glass in the step (3) is 40-50, and the alpha beta mill brick dry powder and the water glass are prepared according to the weight ratio of 2:1 or 2: 1.5.
By adopting the technical scheme, the invention has the following beneficial effects:
1. in order to solve the problem of discharge of solid waste alpha beta brick grinding powder, a novel adhesive prepared from alpha beta brick grinding powder dry powder and water glass is developed, and the adhesive has the advantages of good bonding strength, no toxicity, quick bonding, high temperature resistance, small bonding gap and no pollution to brick materials.
2. The main component of the alpha beta abrasive brick powder is alumina which is similar to the material of a white corundum sand mold, so the alpha beta abrasive brick powder can be reused after the mold is used and broken.
3. The prepared adhesive has improved bonding strength, the bonding strength of the sand mould plate is improved at normal temperature, and no natural cracking phenomenon is found from test results.
4. Compared with the purchased adhesive, the adhesive has good adhesive strength and reduced use amount; compared with the strength, the sand template bonded by the adhesive has the advantages that the template is broken, the bonding part is not cracked, the quality contrast of the brick is influenced, the purchased bonding agent turns red after high temperature, the mold is labor-consuming and time-consuming to detect the bonding agent, the bonding agent enters the brick, and the brick is scrapped; compared with the price, the price of the originally purchased adhesive is more than 1 ten thousand yuan per ton, the labor cost and the equipment loss consumption of the prepared adhesive and the raw material cost are about 6000 yuan per ton, and the (alpha beta abrasive brick powder belongs to solid waste and is not valued) per ton is saved by at least 5000 yuan.
In conclusion, the invention adopts the materials with the same material quality to research and develop the adhesive suitable for the white corundum sand template, which indicates that the main component Al of the white corundum sand mold is Al 2 O 3 The main component of the alpha beta is also alumina, so that the alpha beta corundum brick powder precipitated during processing and cutting grinding is mixed according to a certain proportion by using the performance of water glass (binding agent) and micro powder under the screen through Li water, airing and shade drying to obtain the dry powder, wherein the moisture content is about 2% -5%, the micro powder passes through a vibrating screen with certain fineness, and the micro powder is stirred according to a certain proportion to finally obtain the combined binding agent.
Detailed Description
