Product Description: 1.Test PrincipleThe ISO 5660 standard is an important standard used to measure combustion characteristics such as the heat release rate of materials during combustion. Heat release rate (HRR) refers to the amount of heat released per unit time when a material burns under specified test conditions. For PVC wall panels, measuring their heat release rate can assess their combustion performance in a fire.The test principle is based on the oxygen consumption principle. During combustion, there is a proportional relationship between the heat released and the amount of oxygen consumed. Generally, the heat released per unit mass of oxygen consumed is approximately constant (about 13.1×10³ kJ/kg). By accurately measuring the oxygen consumption during combustion, the heat release rate can be calculated.ØISO 5660-1 Reaction to fire tests—Heat release, smoke production, and mass loss rate—Part 1: Heat release rate (cone calorimeter method) / ISO 5660-1 Reaction to fire tests—Heat release, smoke production, and mass loss rate—Part 1: Heat release rate (cone calorimeter method)2.Test EquipmentThe ISO 5660 heat release rate is tested using a cone calorimeter, which is the core equipment for the ISO 5660 test. It mainly consists of a combustion chamber, sample holder, ventilation system, oxygen analyzer, weighing system, and data acquisition system.The combustion chamber provides a controlled combustion environment, the sample holder is used to secure the PVC wall panel sample, and the ventilation system ensures the supply of air required for combustion and removes combustion products. The oxygen analyzer can accurately measure changes in oxygen concentration during combustion, the weighing system records the mass loss of the sample during combustion, and the data acquisition system collects and processes various test data, such as heat release rate and mass loss rate.3.Test Sample PreparationThe sample dimensions should comply with the requirements of the ISO 5660 standard. Generally, PVC wall panel samples are typically 100mm × 100mm in size, with the thickness based on the actual wall panel thickness, but the flatness and consistency of the sample must be ensured.Multiple samples are usually required to ensure the reliability and repeatability of the test results.4.Sample PretreatmentBefore testing, the samples need to be pretreated, such as conditioning them to constant weight under standard environmental conditions (temperature 23°C ± 2°C, relative humidity 50% ± 5%), to eliminate the influence of moisture and other volatile components in the sample on the test results.5.Test ProcedureMount the specimen horizontally under a radiation cone with a specific radiant flux, insert the spark plug, and ignite the igniter.Data collection is stopped under the following conditions:a)Continuous combustion for 32 minutesb)The specimen fails to ignite within 30 minutesc)The specimen mass becomes zerod)XO2 returns to within 0.01% of the pre-test oxygen concentration value for 10 minutes more>

Product Description: The phenomenon of brittle fracture in metallic materials caused by the combined action of hydrogen and stress is referred to as hydrogen embrittlement fracture. Stress corrosion and hydrogen embrittlement often occur simultaneously. Therefore, it is difficult to clearly distinguish between stress corrosion and hydrogen embrittlement from a mechanistic perspective. However, from a prevention standpoint, distinguishing them is highly necessary.Hydrogen embrittlement typically manifests as delayed fracture under stress. There have been instances where zinc-plated components such as screws, washers, springs, and leaf springs fractured successively within hours after assembly, with a fracture rate reaching 40% to 50%. Hydrogen does not cause significant corrosion to steel under normal temperature and pressure, but when the temperature exceeds 300°C and the pressure is above 30MPa, hydrogen embrittlement—a type of corrosion defect—can occur, especially under high-temperature conditions.The electronic slow strain rate high-temperature high-pressure hydrogen embrittlement stress corrosion testing machine, developed by Xi'an Lichuang Material Testing Technology Co., Ltd., is primarily used to accurately determine the sensitivity of metals to sulfide-induced stress corrosion cracking under H2S exposure. It can also be employed for testing and researching the mechanical properties of metallic materials, such as static persistent tensile strength, creep, and stress corrosion. It is suitable for determining the stress corrosion failure characteristics of metals in environments containing NaOH, NO3-, H2S, CL- solutions, methanol, N2O4, NH3, humid air, water, and other media.Main technical specifications and parameters:1. Maximum test force: 50kN2. Test force range: 1--100% full range without grading3. Accuracy class: Grade 1; indication accuracy better than ±1%4. Equipped with threaded connection fixtures (two types) and pin-type connection fixtures with automatic centering devices;5.

The tensile speed for slow strain rate tests can be continuously adjusted between 10-6 and 1mm/min.7. Test tensile space: 0-400mm, adjustable test space8. Test control methods: force, time, loading rate, step (multi-stage) loading9. Test environment control temperature: room temperature to 300°C10. Reactor withstand pressure: 10MPaSince hydrogen embrittlement is related to the diffusion of hydrogen atoms, and diffusion requires time—with its speed depending on concentration gradient, temperature, and material type—hydrogen embrittlement typically manifests as delayed fracture. Currently, fractures in elastic fasteners caused by delayed hydrogen embrittlement naturally represent a serious product quality issue. Various techniques can be adopted to reduce and prevent hydrogen embrittlement in elastic fasteners. more>

Product Description: Hengwang Activated Carbon - Conventional Specifications of Columnar Activated Carbon:Iodine Value: 1400/1200/1000/800/600/400/200Diameter: 1.5-8mmIntroduction to Columnar Activated Carbon:Columnar activated carbon is made from coal, coconut shell, and wood chips as raw materials. It is widely used in nitrogen purification equipment and air separation nitrogen production equipment, and is particularly suitable for post-stage purification and oil absorption in pressure swing adsorption nitrogen production. It appears as black cylindrical granules.Columnar activated carbon has a very high effective adsorption rate in the field of air purification, with a CTC adsorption rate of over 90%. It also has a good adsorption effect on volatile organic compounds in water, achieving a removal rate of 25% to 65% for various volatile organic compounds in water. Comparing the adsorption patterns of different molecular weight organic compounds, it can be seen that for volatile organic compounds, the larger the molecular weight, the higher the removal rate. This is similar to the adsorption patterns of phenol and cationic嫩黄, meaning that for small-molecule organic compounds in water, the larger the molecular weight, the more easily they are adsorbed by activated carbon.Activated carbon has a good removal effect on extractable organic compounds with a molecular weight below 480, but a low removal efficiency for large-molecule organic compounds. This is mainly due to the steric hindrance effect of the micropore structure of activated carbon; overly large organic molecules cannot enter the pores of activated carbon and can only be adsorbed on the surface.Columnar Activated Carbon Applications:Widely used in gas treatment, sewage treatment, desulfurization and denitrification, solvent recovery, nitrogen generators, air separation equipment, painting workshops, and other fields.For example:Water treatment industry: Columnar activated carbon is used to remove organic matter, odors, pigments, chlorine, and other pollutants from water, making it a key component in the water purification process.Air purification: In air purifiers and gas masks, columnar activated carbon is used to adsorb harmful gases and particles, such as formaldehyde, benzene, and other volatile organic compounds (VOCs).Chemical and pharmaceutical industries: In the refining of chemical products and pharmaceutical processes, columnar activated carbon is used to adsorb impurities and purify products.Food and beverage industry: Used to remove pigments, odors, and impurities from food and beverages, improving product quality.Electronics industry: In semiconductor and electronics manufacturing processes, columnar activated carbon is used to purify gases and chemicals to ensure product quality.Environmental protection: In industrial exhaust gas treatment, columnar activated carbon can adsorb harmful components in gases, reducing environmental pollution.Metal extraction and electroplating: In metal extraction and electroplating processes, columnar activated carbon is used to adsorb metal ions, improving recovery rates and product quality.Solvent recovery: In industries such as chemicals and printing, columnar activated carbon is used to adsorb and recover organic solvents, reducing waste and environmental pollution.Precautions for Using Columnar Activated Carbon:Not all columnar activated carbon can adsorb harmful gases. Only when the pore structure of the columnar activated carbon is slightly larger than the diameter of the harmful gas molecules, allowing them to fully enter (neither too large nor too small), can optimal adsorption be achieved. Currently, the market mainly offers bamboo charcoal and Wujin charcoal crafts. Wujin charcoal is extremely expensive, with an iodine adsorption index of only about 650 mg/g; bamboo charcoal products also have an iodine adsorption index of only about 700 mg/g. Our company's modified columnar activated carbon, compared to similar products on the market, features excellent adsorption performance and high cost-effectiveness. more>
