Burning Rate: Fire Safety’s Key Metric
New 22 10 月, 2025 5
Burning rate quantifies fire risks, guiding material selection and safety design across industries. 1. Definition: Dual Dimensions of Burning Rate As a core parameter in fire science and material flammability assessment, burning rate quantifies the speed of combustion reactions or material ablation. It is expressed in two ways: Chemical Reaction Rate: Measures consumption of reactants (mol/(L·s)) or product generation (kg/(m³·s)) via chemical ki
UL94 Test: Grade & Selection Guide
New 21 10 月, 2025 12
Core Methods of UL94 Test and Thickness Impact The core method of the UL94 test involves using a specified standard flame to ignite a test sample and closely observing the sample’s burning extent, burning speed, whether there is dripping, and whether the dripping substances can ignite flammable materials (such as cotton wool) below. Based on the sample’s thickness, burning behavior, and self – extinguishing ability, it is classi
Diverse Types of Protective Suits for Cleaning Robots
With the advancement of technology, cleaning robots are playing an increasingly important role in our lives. These small yet powerful devices can effectively perform a variety of cleaning tasks, whether in domestic or industrial settings. However, at the same time, protective clothing for cleaning robots has gradually attracted attention. Protective clothing is a crucial tool for protecting robots from contamination, damage, and wear.

What is Bacterial Filtration Efficiency (BFE)?
FAQ 13 10 月, 2025 22
In disease prevention and control, as well as in everyday health care, masks have become an indispensable barrier. However, not all masks offer the same level of protection. One of their core performance indicators is Bacteria Filtration Efficiency (BFE). BFE directly measures the mask material’s most critical ability to block bacterial droplets. Whether in surgical settings, protecting patients from respiratory droplets from doctors, or in
Test methods for rubber ozone aging and how to improve ozone resistance
News 19 9 月, 2025 49
Rubber ozone aging is the deterioration of rubber in the atmosphere. Ozone is a significant factor. Ozone aging first occurs on the surface, particularly at stress concentrations or at the interface between compounding agent particles and the rubber. It typically forms a thin film, which then cracks. If used under dynamic conditions, the film is more likely to break down, exposing a fresh surface. This allows ozone aging to progress further, unti
What is a Salt Spray Tester?
News 19 9 月, 2025 59
Salt spray testing equipment, scientifically known as a “salt spray chamber,” uses salt spray corrosion to test the reliability of the sample under test. Salt spray refers to a diffuse system composed of tiny salt droplets in the atmosphere. It is one of the three types of artificial environmental protection tests. Many companies need to simulate the destructive effects of marine climates on their products, which is why salt spray cha
