On December 2, 2016, the official website of the Guangzhou Bureau of Quality and Technical Supervision announced the results of the 2016 Guangzhou Lubricant Product Quality Supervision and Spot checks. The board recently conducted a random inspection of the quality of Lubricant products in the production areas of the city, sampling a total of 9 companies. The 10 batches of products have been tested to meet the standard requirements. 
Testing lubricant data
Testing lubricant data This random inspection is based on the 2016 Implementation Plan of Guangzhou Lubricants for Quality Supervision and Inspection of Vehicle Lubricants. Its kinematic viscosity, low temperature dynamic viscosity, high temperature and high shear viscosity, foam characteristics, flash point (opening), pour point, and mechanical impurities Thirteen items such as moisture, gel index, sulfate ash, viscosity index, evaporation loss, and sulfur content were examined according to the mandatory national standards GB11121-2006 "Gasoline Engine Oil" and GB11122-2006 "Diesel Engine Oil".
Stainless Perforated Sheet Metal
Stainless Perforated Sheet metal is a versatile material used in various industries due to its unique properties. Here's a breakdown of what it is, its applications, and why it's preferred over other materials in certain situations:
What is Stainless Perforated Sheet Metal?
Stainless perforated sheet metal is made from stainless steel, which is an alloy of iron, carbon, and chromium. The chromium content gives stainless steel its corrosion-resistant properties. Perforated sheets are created by using a die and a punch to create holes or slots in the metal, resulting in a material that has a pattern of openings.
Types of Perforations
- **Round Holes**: The most common type, providing uniform spacing.
- **Square Holes**: Offer more flexibility in design and application.
- **Diamond Holes**: Provide a stronger structure due to their interlocking nature.
- **Staggered Holes**: Enhance airflow and light penetration while maintaining structural integrity.
Applications of Stainless Perforated Sheet Metal
1. **Industrial Uses**:
- **Exhaust Systems**: Used for filtration and noise reduction.
- **Ventilation Grilles**: Facilitates air flow while preventing access to machinery or equipment.
- **Roofing and Cladding**: Provides aesthetic appeal and protection against rain and wind.
2. **Construction**:
- **Facade Panels**: Adds a decorative element while allowing light and air to pass through.
- **Window Screens**: Protects from insects and security threats while allowing natural light.
3. **Agricultural Use**:
- **Hay Bales and Grain Storage**: Allows air circulation without compromising structural integrity.
4. **Food Processing Industry**:
- **Sieve Baskets and Shakers**: Used for sieving and separating food products.
- **Ventilation in Processing Plants**: Ensures proper air circulation and temperature control.
5. **Art and Design**:
- **Decorative Panels**: Used in art installations and architectural designs for their aesthetic qualities.
Advantages
- **Corrosion Resistance**: Stainless steel's high chromium content makes it resistant to rust and corrosion, ideal for outdoor applications.
- **Strength and Durability**: Despite the perforations, the metal maintains significant strength and durability.
- **Easy Maintenance**: Its non-porous surface reduces the risk of bacterial growth and requires minimal cleaning.
- **Aesthetic Appeal**: The perforated patterns can enhance the visual appearance of structures or installations.
Conclusion
Stainless perforated sheet metal offers a combination of functional benefits and aesthetic possibilities, making it a popular choice across various industries. Its unique properties, such as corrosion resistance and strength, coupled with its versatile applications, make it a valuable material for many construction and industrial projects.
