Product Description:   Baking: Apply a red flame (or use a dedicated annular baking tool) starting from one end, moving uniformly along the circumference of the heat-shrink tube (it is strictly forbidden to move the flame along the long axis or to let it stay in one place). Once one full circumference has shrunk properly, gradually extend the heating (note: heat uniformly one circumference at a time, rather than moving straight along the axis, otherwise it may cause surface wrinkling or cracking). During the baking process, promptly apply gentle pressure to the already shrunk areas using a smooth roller (a roller or rod matching the shape and size of the corrugation) or while wearing heat-resistant gloves, ensuring it fits snugly against the waveform and removing any residual air (be careful not to scorch the bellows). When the heating shrinkage reaches about 5cm from the end, turn the flame to heat the hot melt adhesive on the inner wall of the heat-shrink tube, then switch to the outer wall. After the heat-shrink tube is fully shrunk, use a low flame to evenly heat the entire area (to fully melt the hot melt adhesive) until the hot melt adhesive begins to seep out from the ends. It is important to emphasize that the flame heating temperature must be properly controlled: neither too high, which could burn the outer wall of the PE tube and cause the end of the heat-shrink tube to crack, nor too low, which would prevent the hot melt adhesive from fully melting and bonding firmly, failing to meet the required peel strength. more>

Optical System: The optical system is responsible for transmitting the laser beam generated by the laser generator to the cladding head, ensuring stable transmission and precise control of laser energy.3. Cladding Head: The cladding head is the execution part of the laser cladding equipment. It focuses the laser beam onto the surface of the workpiece, achieving rapid melting and solidification of the material to form the cladding layer.4. Worktable: The worktable is used to carry the workpiece. Through precise motion control, it enables the relative movement between the laser beam and the workpiece, completing the cladding process.5. Control System: The control system is the brain of the laser cladding equipment. It is responsible for controlling the start and stop of the laser generator, adjusting the optical system, moving the cladding head, and precisely positioning the worktable.II. Key Configuration Factors of Laser Cladding EquipmentWhen selecting laser cladding equipment, the following key configuration factors need to be considered:1. Laser Power: Laser power is one of the most important parameters in the laser cladding process, directly affecting the quality and efficiency of the cladding layer. Generally, higher laser power results in greater depth and width of the cladding layer and higher production efficiency. However, excessively high laser power may cause material ablation and overly rapid melting, affecting the performance of the cladding layer. Therefore, when selecting laser power, it is necessary to balance process requirements and material characteristics.2. Spot Size: Spot size refers to the focused diameter of the laser beam on the workpiece surface. Spot size directly affects the shape and quality of the cladding layer. A smaller spot enables finer cladding but may also result in slower cladding speeds. Therefore, when selecting spot size, it is necessary to balance the precision and efficiency requirements of the cladding layer.3. Scanning Speed: Scanning speed refers to the speed at which the laser beam moves across the workpiece surface. Faster scanning speeds increase production efficiency but may also lead to a decline in cladding layer quality. Therefore, when selecting scanning speed, it is necessary to balance the performance requirements of the cladding layer and production efficiency.4. Powder Feeding System: The powder feeding system is responsible for delivering the cladding material to the cladding head, ensuring the smooth progress of the cladding process. The stability and accuracy of the powder feeding system significantly impact the quality of the cladding layer. When selecting a powder feeding system, factors such as its powder feeding capacity, powder particle size adjustment range, and powder utilization rate need to be considered.5. Control System Precision: Control system precision refers to the accuracy with which the control system manages components such as the laser generator, optical system, cladding head, and worktable. Higher control system precision results in better forming quality of the cladding layer and higher production efficiency. Therefore, when selecting laser cladding equipment, it is necessary to consider whether the precision of its control system meets process requirements.III. Selection Strategy for Laser Cladding EquipmentWhen selecting laser cladding equipment, the following aspects need to be comprehensively considered:1. Clarify Process Requirements: First, you must clarify your process requirements, including the type of cladding material, the thickness and width of the cladding layer, cladding speed, production efficiency, and other requirements.

Through on-site visits, you can understand the equipment's appearance, structure, and operating environment. By trialing the equipment, you can personally experience its ease of operation, stability, cladding effects, and other performance aspects. This will help you gain a more comprehensive understanding of the equipment's actual condition, enabling you to make a more informed choice.4. Consider Cost and Return on Investment: When selecting laser cladding equipment, it is also necessary to consider cost and return on investment. The price of laser cladding equipment varies depending on factors such as brand, model, and configuration. When selecting, you need to balance your budget and expected benefits to choose equipment with high cost-effectiveness. Additionally, factors such as equipment maintenance costs, consumable costs, and operating costs need to be considered to ensure long-term stable operation and profitability of the equipment.In summary, selecting the configuration of laser cladding equipment is a complex and important process. Choosing the right configuration requires comprehensive consideration of various factors, including the type and power of the laser generator, the performance of the optical system, the stability and accuracy of the powder feeding system, the load capacity and motion precision of the worktable, and the programming capability and ease of operation of the control system. When selecting equipment, it is recommended to balance these factors based on your actual needs and budget, and refer to the opinions and suggestions of professionals. Additionally, attention should be paid to the maintenance and upkeep of the equipment to ensure its long-term stable operation and efficient production. more>

Product Description: Selecting the appropriate aeration pad or aeration channel for a specific pneumatic conveying system requires comprehensive consideration of material characteristics, system parameters, equipment installation, and other factors. The specific selection methods are as follows: • Consider material characteristics ◦ Particle size: For fine powdery materials that are easy to fluidize, such as cement raw meal or fly ash, aeration pads or channels with good air permeability can be selected. If the material has a larger particle size or irregular particle shape, higher air permeability and larger pore sizes may be required to ensure adequate fluidization.  • Consider system parameters ◦ Conveying capacity: Select the appropriate specifications of aeration pads or channels based on the conveying capacity requirements of the pneumatic conveying system. Generally, the larger the conveying capacity, the greater the area or number of aeration pads or channels required. For example, for systems with high conveying capacities, multiple aeration pads can be used in combination, or wider aeration channels can be selected. ◦ Operating pressure: Understand the system's operating pressure to ensure the selected aeration pad or channel can withstand it. The design pressure of the aeration pad or channel should be higher than the system's operating pressure to ensure equipment safety and stability. ◦ Compressed air flow rate: Compressed air flow rate is one of the key factors affecting material fluidization. Based on material characteristics and conveying capacity, calculate the required compressed air flow rate and select aeration pads or channels that can provide sufficient air flow. • Consider installation location and space ◦ Installation location: If the aeration pad or channel is installed at the bottom of a silo, consider the silo's shape and dimensions, as well as the location and number of discharge outlets. For flat-bottom silos, aeration channels can be evenly arranged; for conical-bottom silos, aeration pads can be installed at the cone bottom. ◦ Space constraints: If the installation space for the pneumatic conveying system is limited, choose compact aeration pads or channels that occupy minimal space. For example, small aeration pads or embedded aeration channels can be selected. • Consider equipment material and quality ◦ Material: The material of the aeration pad should have good air permeability, wear resistance, and corrosion resistance. Common materials include silicon carbide and stainless steel. Silicon carbide aeration pads offer high strength and wear resistance, making them suitable for conveying most powdery materials; stainless steel aeration pads provide better corrosion resistance and are suitable for conveying corrosive materials. ◦ Quality: Choose reliable aeration pads or channels by evaluating factors such as manufacturing processes and brand reputation. High-quality aeration pads or channels should have good sealing, uniform air permeability, and a long service life. more>

Product Description: MAOS (CASNo.: 82692-97-5), also known as N-ethyl-N - (2-hydroxy-3-sulfopropyl) -3,5-dimethylaniline sodium salt monohydrate, is a very important member of the new Trinder's reagent family. It's not as commonly used as TOOS, but But it also has an absolutely irreplaceable role. Like other new color reagents, they have high water solubility and much higher sensitivity than traditional color reagents commonly used in some laboratories, making them widely used in clinical testing and biochemical reagent kits. MAOS has a high absorption wavelength The biggest characteristic of MAOS is that the maximum absorption wavelength of its oxidized product far exceeds that of ordinary color reagents. Even in the new Trinder's reagent, its product has a relatively high UV absorption wavelength of 630nm. The maximum absorption wavelength of many color reagent products is in the visible light region. If it is used to detect human blood or other body fluids, due to the complexity of the components in the sample to be tested, the sample itself contains a small amount of components with absorption wavelengths in the visible light region or similar to the absorption wavelength of the color product, which will result in higher detection results. If using MAOS, the maximum absorption wavelength of the product is in the ultraviolet region and relatively high, it will greatly reduce interference. Therefore, for some biochemical testing items that require highly accurate values, it is recommended to use MAOS as the chromogenic substrate. PH value of MAOS Secondly, the color reaction of MAOS chromogenic substrate has a wide adaptability range to the pH of the reaction system, greatly improving its adaptability Sex. Some color reagents often react under slightly acidic conditions, but enzyme involvement is usually required in biochemical testing. We know that enzyme catalysis is sensitive to the pH of the reaction environment, and it may even become inactive if it does not match the color reagents. Its use is greatly limited, while MAOS reagents do not have this problem. Molar absorbance of MAOS Another point is that the molar absorption intensity of MAOS color reaction is relatively high, so its sensitivity is also relatively high. Attention Required However, when the detection time is too long, MAOS may fade, so MAOS detection needs to be completed in a timely manner and cannot be interrupted. In addition, MAOS is also relatively safe, unlike DAB and other biphenyl chromogenic reagents, which are relatively inexpensive but have Has certain carcinogenicity or mutagenicity. Storage of MAOS MAOS is sensitive to light and humidity, so it has high storage requirements. It is necessary to use containers that are well shaded and sealed, with a temperature of 0-5 ℃. It is best to store them in cold storage, while also paying attention to avoiding light and moisture to ensure higher and more accurate testing quality. Desheng Technology has always been committed to the research and development, production, and sales of chromogenic substrates, especially TOOS, MAOS, ADPS, etc., which have a good reputation both domestically and internationally. We have good cooperative relationships with many biochemical reagent kit manufacturers. Let's work together to add bricks and tiles to the field of domestic diagnostic reagents! more>

Product Description:         Molybdenum disilicide bubbling tubes are primarily used in the glass industry. The bubbling tubes are installed in glass furnace tanks, where clean, compressed air is introduced into the tank through professional and clean compressed air systems. This helps to reduce the temperature difference between the upper and lower parts of the furnace tank. By generating tiny bubbles, small air bubbles and trace impurities in the glass melt are carried away, thereby improving the purity and quality of the glass. After years of improvement and innovation, Zhengzhou Yixin Kiln Co., Ltd.'s molybdenum disilicide products undergo surface physical treatment, which enhances the purity of molybdenum disilicide in glass furnace tanks and reduces secondary pollution.      Molybdenum disilicide (MoSi₂) is an intermediate phase in the Mo-Si binary alloy system with a high silicon content. It possesses dual characteristics of both metals and ceramics, making it an excellent high-temperature material. It exhibits excellent high-temperature oxidation resistance, with an oxidation resistance temperature as high as 1600°C or above, comparable to SiC. It has a moderate density (6.24 g/cm³), a relatively low thermal expansion coefficient (8.1×10⁻⁶ K⁻¹), and good electrical and thermal conductivity. Although molybdenum disilicide demonstrates high oxidation resistance and Young's modulus at temperatures above 1000°C, it is brittle at low temperatures. Additionally, it loses creep resistance at temperatures exceeding 1200°C, which limits its application as a structural material. However, when combined with other materials, it can be used in composites to enhance mobility. Molybdenum disilicide and materials based on it are typically produced through sintering, such as molybdenum disilicide protection tubes. Plasma spraying can be used to produce dense monolithic and composite forms of the material. For rapid cooling, a small amount of β-modified molybdenum disilicide is often included. Leveraging its high-temperature resistance, molybdenum disilicide is made into bubbling tubes and widely used in the glass industry for purifying glass melts.        The 9-hole molybdenum disilicide bubbling tube is currently the type with the most holes on a 16mm diameter. With holes approximately 1mm in diameter, compressed air is injected into the glass melt, effectively removing finer impurities and resulting in higher glass purity. more>
