Problems solved by technology

[0006] Aluminum profile factory sludge (hereinafter referred to as sludge) is the industrial waste generated by the coagulation process of the waste water produced during the processing of aluminum profiles. It is mainly composed of colloidal aluminum hydroxide and has a high aluminum content. At present, most aluminum profiles The factory simply stacks and disposes this kind of sludge, which not only occupies a large amount of land, but also causes potential pollution to the environment; therefore, how to safely and effectively dispose or utilize this kind of sludge has aroused widespread concern

Abstract

An expendable pattern casting coating superior in using performance and low in production cost is prepared with high-aluminum blast furnace slag, aluminum profile plant sludge, magnesia, quartz milltailings, pyrite tailings, montmorillonoid, lithium-base bentonite, zinc-aluminium spinel fine powder, glass beads, sepiolite, volcaniclastic rock, zirconium phosphate, N-beta(aminoethyl)-gamma-AEAPTMS, isopropyl tri (dioctyl phosphoryl group) titanate, polyacrylate, polyethylene wax, chlorinated polyethylene, fatty alcohol-polyoxyethylene ether, methyl methacrylate, polyvinyl alcohol fiber, sodium hexametaphosphate, sodium dehydroacetate, ethanol and water as raw materials. The purposes of comprehensively recycling high-aluminum blast furnace slag and aluminum profile plant sludge and reducing the production cost are achieved.

Description

technical field [0001] The invention belongs to the field of lost foam casting coatings, in particular to a high-alumina blast furnace slag-aluminum profile factory sludge lost foam casting coating and a preparation method thereof. Background technique [0002] Lost foam casting technology is a new casting process in the foundry industry. The lost foam casting process refers to making foam plastic (EPS, ETMMA or EPMMA) into the shape, structure and size of the required castings. After the refractory coating is dried, it is embedded in a special sand box with dry sand (usually quartz sand) for molding, and then poured under a certain negative pressure. Lost foam casting is mainly called dry sand solid mold casting and negative pressure solid mold casting in China, and it is referred to as EPC casting abroad. [0003] At present, the most mature lost foam casting process is used in the mass production of automotive castings. The products produced include aluminum alloy castin...
