Benefits of technology

This patented technology improves how small particles called silicate wires (SiW) or metal foils made from metals like gallium nitride have been modified by adding certain substances such as iron chlorides or cobalt acids. These modifications enhance their properties for use in applications where they were previously used only as fillings. They also help prevent cracks caused by thermal stress when casted into glass products. Additionally, these modification make them more stable against chemical attack than other materials commonly found within the manufacturing process. Overall this innovation makes possible better quality optical components while maintaining good performance characteristics over time.

Problems solved by technology

Loss foam foundry involves creating an expensive investment for new materials called lost foams or ceramic cores. These losses may result from improving their ability to resist damage caused by corrosion when poured into steel without leaving any residue behind inside them. To solve this problem, there have been various techniques proposed including adding specialized particles like talcum powders (a type commonly known) to enhance fluidity and reduce friction between the solidified shell layers of these lost foils. Additionally, some methods involve modifying existing loss foam compositions through specific processes involving mixing different types of raw ingredients together.

Embodiment Construction

[0014] A mica powder modified quartz-based lost foam coating containing floating beads, made of the following raw materials in parts by weight (kg): quartz powder 100, modified starch 0.9, carboxymethyl cellulose 0.9, sodium bentonite 2.4, mica powder 0.9, four-needle zinc oxide whisker 0.8, silica sol 0.9, ethanol 10, water, hydrogen peroxide 0.6, floating beads 0.6, ceric sulfate 0.2.

[0015] The preparation method of the mica powder modified quartz-based lost foam coating containing floating beads may further comprise the steps:

[0016] (1) Add silica sol to ethanol, stir evenly, then add mica powder and stir evenly, heat to 60°C, add four needle-shaped zinc oxide whiskers while stirring, heat to 70°C, ultrasonically disperse for 3 minutes, continue stirring until After ethanol volatilization is completed, pulverize and pass through a 100-mesh sieve to obtain modified mica powder;

[0017] (2) Mix hydrogen peroxide and ceric sulfate to obtain a mixed liquid, and spray th...

Abstract

The invention discloses floating-bead-contained mica powder modified quartz-based lost foam paint which is prepared from the following raw materials in parts by weight: 100-102 parts of quartz powder, 0.9-1.1 parts of modified starch, 0.9-1.1 parts of carboxymethyl cellulose, 2.4-2.6 parts of sodium bentonite, 0.9-1 part of mica powder, 0.8-0.9 part of tetrapod-shaped zinc oxide whiskers, 0.9-1.1 parts of silica gel, 10-13 parts of ethanol, a proper amount of water, 0.6-0.8 part of hydrogen peroxide, 0.6-0.7 part of floating beads and 0.2-0.3 part of ceric sulfate. As the floating beads are modified with hydrogen peroxide and ceric sulfate, the surfaces and the interiors of the floating beads are filled with hydrogen peroxide and ceric sulfate, the combustion of organic matters can be promoted in casting, the accumulation of carbon can be reduced, the air permeability can be improved, and the air permeability can be further improved due to hollow structures of the floating beads.
