Welcome to the website for landscape facilities products and knowledge.
How do manufacturers test the resistance of landscape chairs to oils, sunscreen, and other common outdoor substances?
Manufacturers rigorously test landscape chairs to ensure they withstand exposure to oils, sunscreen, and other common outdoor substances. These tests simulate real-world conditions to evaluate durability and material integrity.
1. Material Selection: Chairs are made from UV-resistant, non-porous materials like polyethylene or powder-coated metal to minimize staining and degradation.
2. Controlled Exposure: Samples are coated with oils, sunscreen, or other substances and exposed to sunlight, humidity, and temperature fluctuations in climate chambers.
3. Abrasion Testing: Mechanical scrubbers simulate repeated contact with these substances to assess surface wear and colorfastness.
4. Chemical Resistance: Labs use standardized protocols (e.g., ASTM standards) to measure how materials react to chemicals without cracking or fading.
5. Real-World Trials: Chairs are placed in high-traffic outdoor areas (e.g., pools, parks) for long-term observation.
Results guide improvements in coatings and designs, ensuring chairs remain functional and aesthetically pleasing despite harsh outdoor conditions.
