Green Silicon Carbide for Sandblasting Aluminum Alloy Panels Green silicon carbide (SiC) is a widely used abrasive material for sandblasting aluminum alloy panels, thanks to its high hardness, sharp edges, and good chemical stability. Below is a detailed analysis of its application characteristics, advantages, operating precautions, and alternatives. 1. Core Advantages of Green Silicon Carbide
Green Silicon Carbide for Sandblasting Computer Screens Overview Green silicon carbide (SiC) is an ultra-high-purity synthetic abrasive widely used for precision surface finishing of electronic display glass, particularly computer/device screens requiring controlled matte/textured finishes. Key Properties Chemical & Physical Characteristics: Purity: >99% SiC (vs. ~95% for black SiC) Hardness: 9.2-9.5 Mohs (second only to diamond/boron carbide) Crystal
What is “Chip Blasting”? In this context, “chip blasting” likely refers to abrasive blasting or shot blasting, but with a very fine, controlled abrasive. It’s used for precision cleaning, deburring, surface texturing, and preparing surfaces for coatings—not for aggressive stripping of heavy materials. The use of silicon carbide, one of the hardest common abrasives, indicates
Green Silicon Carbide (GC) 220# is well-suited for the roughing and intermediate grinding stages of alumina ceramics due to its high hardness and sharp cutting ability. 1. Why Green Silicon Carbide (GC) is the Right Abrasive High Hardness: GC has a Mohs hardness of about 9.2-9.5, which is higher than alumina ceramic (approx. Mohs 9). This
The Core Principle: Surface Preparation is Everything For a non-stick coating (like PTFE/Teflon or ceramic) to adhere properly and have a long service life, the substrate (usually aluminum or stainless steel) must be perfectly prepared. This preparation involves three key steps, and GSiC is crucial for the first one: Cleaning & Degreasing Abrasive Blasting (The
1. Core Function: Superior Surface Preparation The primary goal of surface preparation is to create a surface that allows the coating to adhere perfectly. This involves: Cleaning: Removing all contaminants (rust, mill scale, old paint, salts, oil). Creating a Profile (Anchor Pattern): Etching the metal surface to increase its surface area and create mechanical “teeth”
