EMIN - DRAMINSKI: Cùng hợp tác tham gia Triển lãm Agroviet 2013

Many used car buyers often spend a considerable amount of time examining the paintwork, the gaps between body panels, or the overall condition of the exterior. However, these signs can be skillfully masked following repairs; precise color matching and careful polishing can make the vehicle appear almost factory-original.

A fire-retardant coating only provides effective protection when applied to the specified design thickness. A shortfall of even a few hundred microns can significantly reduce fire resistance, whereas an excessively thick coating is prone to cracking and peeling, in addition to increasing material costs

Water resistance is a common requirement for a wide range of modern products, spanning industrial sensors, outdoor LED lights, medical devices, and water filter cartridges to electronic components and automotive parts. When exploring manufacturing technologies, many businesses often ask the same question: can ultrasonic welding truly create a watertight seal?

A satisfactory ultrasonic weld must form a uniform bond across the entire contact surface. The presence of gaps, edge separation, or partial adhesion significantly compromises airtightness, watertightness, and mechanical strength. This is a common issue in the manufacturing of plastics, electronic components, packaging, and medical devices, particularly following a product changeover or an adjustment of welding parameters on the production line.

Hanoi's air quality has shown signs of improvement following the introduction of E10 gasoline. What do the monitoring data indicate, and which indicators should be tracked to ensure an objective assessment?
