What to do after polishing: Comprehensive guide and hot topics analysis
As an important surface treatment process, polishing is widely used in metal, stone, wood and other fields. But the subsequent processing after polishing is also critical, directly affecting the quality and life of the finished product. This article will combine hot topics on the Internet in the past 10 days to provide you with a detailed analysis of the post-polishing processing steps, precautions and the latest trends in the industry.
1. Core steps of post-polishing treatment
| steps | Operation content | Applicable materials |
|---|---|---|
| Cleaning and decontamination | Use special cleaners to remove polish residue | Metal/Stone/Plastic |
| Surface passivation | Chemical treatment forms protective film | Stainless steel/aluminum alloy |
| coating protection | Spray varnish or coating | Car paint/furniture |
| Anti-oxidation treatment | Apply anti-rust oil or wax | Precision instruments/decorative parts |
2. Inventory of recent hot technologies (TOP5 search popularity in the past 10 days)
| Technical name | heat index | Main application areas |
|---|---|---|
| Nano coating technology | 9.2 | Mobile Phone Case/Car Beauty |
| Electrolytic polishing post-treatment | 8.7 | Medical equipment/food machinery |
| self-healing coating | 8.5 | High-end electronic products |
| Environmentally friendly passivation agent | 8.3 | Hardware products |
| Laser sealing glaze | 7.9 | jewelry |
3. Comparison of post-processing solutions for different materials
| Material type | Recommended treatment | Effect duration |
|---|---|---|
| stainless steel | Electrolytic passivation + nano coating | 3-5 years |
| Aluminum alloy | Anodizing + sealing | 2-3 years |
| natural stone | Crystallization treatment + penetration protection | 1-2 years |
| car paint | Crystal plating + car clothing | More than 5 years |
4. Solutions to common problems
Based on recent high-frequency discussions in industry forums, we have sorted out how to deal with three typical problems:
1. Mist marks appear after polishing:This is mostly caused by polishing paste residue or over-polishing. It is recommended to use a pH-neutral special cleaner and use a microfiber cloth to wipe in one direction.
2. Rapid oxidation of metal parts:The recent humid climate areas have strongly reflected this. The solution is to use VCI vapor phase anti-rust technology and add corrosion inhibitors to the packaging process.
3. Poor coating adhesion:It is necessary to check whether the surface energy reaches the standard. The new trend is to use plasma treatment instead of traditional grinding to increase the bonding strength by more than 30%.
5. Environmental protection requirements and industry specifications
As environmental protection policies tighten, the newly implemented "Surface Treatment Pollutant Emission Standards" in 2023 puts forward higher requirements for post-treatment processes:
| pollutants | Limit standard | Standard technology |
|---|---|---|
| volatile organic compounds | ≤50mg/m³ | Water-based paint alternatives |
| heavy metal ions | ≤0.5mg/L | Membrane separation and recycling |
| pH | pH6-9 | Neutralization processing system |
6. Future development trends
According to recent industry exhibitions and technical white papers, post-polishing treatment technology is developing in three directions: intelligence (AI quality inspection system), green (bio-based protective agent), and multi-functional (oleophobic and hydrophobic integrated coating). It is recommended that practitioners pay attention to technological upgrades in these areas.
Through the above structured data and analysis, we hope to help you systematically grasp the key points of post-polishing treatment. In actual operation, it is necessary to choose the appropriate solution according to the specific working conditions. It is recommended to participate in technical training regularly to master the latest technology.
