Product Description: Flexible roundlifting slings are characterized by their soft and easy-to-place straps. Due to their special manufacturing process, lifting sling manufacturers can produce round slings with a load capacity of over 100 tons, enhancing the load range of lifting tools and making synthetic fiber slings more widely applicable.The bearing surface width of large-tonnage round slings is smaller than that of flat slings of the same tonnage. When lifting certain objects in specific scenarios, round slings are more convenient to use than flat slings, as they are not restricted by the width of the lifting gear, avoiding situations where the eye width is too broad to be properly placed.The use of lifting tools begins with understanding the production information of Hebei sling manufacturers, as well as the usage methods and precautions of lifting gear, to prevent losses and accidents caused by lack of knowledge.

Product Description: Drug Melting Point Apparatus refers to the temperature at which a substance changes from solid to liquid. Different substances and different purities have different melting points. Therefore, the determination of melting point is one of the important methods for identifying substances and their purity. Thus, the determination of melting point holds a significant position in industries such as chemical and pharmaceutical industries. The melting point apparatus is an instrument used for the identification and study of drugs, fragrances, dyes, and other crystalline substances.Drug Melting Point Apparatus uses a mercury thermometer for measurement and a pointer voltmeter to adjust the heating power, representing the traditional old-fashioned original melting point determination method, which is reliable and accurate. The instrument electronically heats the melting point capillary tube, controls the heating rate by adjusting the voltage, and observes the bright melting process through a magnifying glass. The traditional mercury thermometer is used to determine the initial and final melting point temperatures.Technical Parameters:1. Temperature measurement range: 50-300°C2.

Product Description: Working Principle of the SDQ-50 Deep Hole Rapid Sampling Device:During normal drilling, it operates similarly to the drilling principles currently used in mines, where both the inner pipe of the double-wall drill pipe and the annular space simultaneously convey air and discharge cuttings. For sampling, the reverse circulation drilling principle is employed: compressed air enters through the annular space of the double-wall drill pipe and blows the coal samples cut by the cyclone jet sampling bit out under positive pressure through the inner pipe of the double-wall drill pipe, achieving rapid sampling.The transport speed of coal samples in the inner pipe of the SDQ-50 Deep Hole Rapid Sampling Device can reach 15 m/s.Technical Requirements for the SDQ-50 Deep Hole Rapid Sampling DeviceDrill Pipe: Diameter 50 mm, torque ≥ 4000 N/m, equipped with φ25 quick-connect couplingsDrill Bit: Diameter 75 mm, length not less than 200 mmSampling Speed: >250 g/min;Rated Working Air Pressure: 0.55 MPa;Rated Working Air Volume: 4–5 m³/min (standard conditions);Rated Sampling Depth: 0–50 m (varies depending on geological conditions);Compatible Drill Rig Requirements: Capable of clamping Φ50 mm drill pipe, rear-mounted tail whip; equipped with φ25 and φ32 quick-connect couplings Sampling Device Deep Hole Rapid Sampling Device Coal Seam Gas Sample Sampling Device Coal Seam Gas Sampling DeviceThe SDQ-50 Deep Hole Rapid Sampling Device complies with GB/T23250-2009 "Direct Determination Method of Coal Seam Gas Content Underground." The core of determining coal seam gas content lies in the estimation of loss, with the current technical bottleneck being sampling. The deep hole rapid sampling device standard requires "fixed-point sampling, with a sampling time of less than 5 minutes."Zhengzhou Aidi produces and supplies coal drill cuttings desorption instruments, deep hole sampling devices, pressure measuring instruments, geological exploration desorption instruments, borehole flow meters, mine gas extraction and outburst prevention equipment, true density measuring instruments for coal, gas content measuring instruments, automatic initial gas emission speed measuring instruments, diffusion speed measuring instruments, coal gas extraction pipeline gas parameter instruments, and borehole coal powder circulation devices. more>

When the air compressor system is operating normally, the system pressure is ≤0.785MPa (8kgf/cm²). Under this pressure, the pressure relief valve functions normally. When the air tank ignites due to carbon buildup or the gas inside the tank becomes dangerous for some reason, the temperature and pressure in the system instantly rise. When the pressure reaches 1.04±0.059MPa (10.6±0.6kgf/cm²), the pull rod immediately breaks, the pressure relief valve releases pressure, and the high-temperature, high-pressure gas in the air tank and pipeline is rapidly released, thereby mitigating shock waves and preventing major accidents. more>

Product Description: The Chinese name of MADB is N, N-di (4-sulfobutyl) -3,5-dimethylaniline sodium salt, with a CAS of 209518-16-1. It is a highly water-soluble and sensitive peroxidase chromogenic substrate commonly used in laboratories. It can react with peroxidase to form a complex, and this complex can achieve the purpose of detecting peroxidase activity through colorimetric reactions, thereby evaluating the immune function of cells, the proliferation ability of tumor cells, and the toxicity of environmental pollutants to organisms. Below, we will take you to analyze the role of MADB in detail. 1、 Substrate action The main function of MADB as a chromogenic substrate is to provide a reactive chemical structure to convert the reactive oxygen species generated by peroxidase enzymes into visible products. Because in this process, the structure of MADB has specific binding sites with the reaction products catalyzed by peroxides and enzymes, making the binding between substrates and enzymes tighter and more stable. 2、 Color change effect When MADB reacts with peroxidase, the substrate is oxidized into an unstable intermediate, which is then converted into a stable product through the reduction of MADB. During this process, the color of the substrate will change, which can be used to evaluate the activity and stability of peroxidase, as the more active the enzyme, the more intermediates and products it produces, resulting in a more pronounced change in substrate color. 3、 Signal amplification effect In addition to the role of the substrate itself, MADB can also enhance enzyme reaction efficiency through signal amplification. This is because the binding site between MADB and enzymes is highly specific, and only substrates that conform to a specific structure can react with it. Therefore, MADB has a high affinity and can be effectively catalyzed, precisely achieving this. In summary, as a peroxidase chromogenic substrate, MADB has multiple functions, which together constitute its unshakable position in color experiments. At the same time, it also provides researchers with a fast, sensitive and reliable method to help them complete complex experimental operations. As an advantageous supplier of color reagents, Desheng has developed a new type of Trinder's reagent that can be applied to various biochemical experimental projects. It not only has high purity, but also has sensitive and stable color development, and is cost-effective.
