$65
Category: Chemicals/Phenols/Hydroquinone
Company:
Product Description: Product Advantages: Aesthetic, durable, short construction period, the entire pavement can be formed in one go (cast-in-place tactile paving can be directly laid on the finished pavement, avoiding the hassle of secondary paving typically caused by traditional tactile paving bricks), significantly reducing pavement construction costs and material waste. Various colors and styles are available for flexible matching.Product Description: Polymer cast-in-place diamond tactile paving is a continuous tactile paving system made on existing pavement using inorganic high-strength polymer materials and specialized molds, available in two types: guiding strips and guiding dots. Standard widths are 300mm, 400mm, 500mm, and 600mm, with flexible customization based on actual needs. It forms a permanent bond with asphalt concrete or cement concrete base layers, offering wear resistance, slip resistance, stain resistance, and synchronous expansion and contraction with asphalt pavement.II. Construction Process and Operating MethodsPolymer cast-in-place diamond tactile paving is a new tactile paving technology that can be constructed on-site on traditional black asphalt concrete and gray cement concrete pavements.2.1 Construction ProcessBase layer inspection - Base layer cleaning and treatment - Layout marking - Tape application - Base leveling and mortar spreading - Mold placement - Filling with diamond tactile paving mortar - Leveling and finishing - Curing to specified time - Surface cleaning - Application of sealant for surface sealing - Drying and curing - Inspection - Opening to traffic - Final acceptance.2.2 Construction Equipment and ToolsThe diamond tactile paving construction process is relatively simple, requiring only the following equipment and tools: one mixer, one disperser, several tactile paving molds, one material transport vehicle, rolling rollers, specialized serrated rubber screeds and flat rubber screeds, one powerful blower, one generator, brooms, and other general equipment and tools.2.3 Construction PersonnelOne team leader and 5-6 construction workers per group.2.4 Construction Preparation4.1 Review drawings and layout markingCarefully review construction drawings and verify positions on-site one by one; if necessary, mark points and apply tape.4.2 Material inspectionPolymer cast-in-place diamond tactile paving is an on-site, multi-step, multi-material coordinated construction system. Before construction, check the consistency of materials and compatibility among various materials. Emulsion materials should show no significant skinning, clumping, or abnormalities; powder materials should be free of clumps. 2.4.3 Trial mixing and sample preparationDifferent base layers and environments can affect the curing time of polymer diamond tactile paving. Therefore, before formal construction, conduct on-site trials strictly according to the mix ratio and method set for batch operations. Proceed with batch operations only after ensuring no obvious defects in curing.2.4.4 Base layer conditions and treatmentThe base layer should be solid and clean. Asphalt concrete pavement should be free of bleeding, loose dust, delamination, or aggregate loss.For cement concrete pavement with strength below C25, the surface should be treated by milling, scabbling, grinding, sandblasting, or roughening (for new concrete), preferably exposing the aggregate over a large area. Additionally, apply 1-2 coats of PM-101 penetrating sealant for sealing treatment.Clean, dry asphalt pavement in good functional condition does not require sealing treatment. more>

Q390E steel, introduction to the reasons for unqualified low-temperature impact of Q390E steel plate
$5000
Category: Others
Company:
Product Description: The reasons for the failure of low-temperature impact in Q390E steel may include the following aspects:Unreasonable chemical composition. For example, excessively high carbon content or excessively low manganese content may lead to failure in low-temperature impact.Inappropriate heat treatment process. During heat treatment, temperature and cooling rate directly affect the low-temperature toughness of the steel plate. Excessively high or low temperatures, as well as excessively fast or slow cooling rates, may result in reduced low-temperature impact performance.Unreasonable coil forming process. During the forming process, the steel plate undergoes significant stretching and compression, which may cause cracks and fractures at low temperatures, thereby reducing low-temperature impact performance.Unreasonable content of alloying elements. The content of elements such as chromium and nickel is related to low-temperature strength. Chromium can improve the corrosion resistance of steel but has little effect on low-temperature toughness, while nickel can improve the toughness of steel but has little effect on corrosion resistance. Therefore, appropriate additions of elements such as nickel and chromium can simultaneously enhance the toughness and corrosion resistance of the steel plate, thereby improving its low-temperature impact performance.To address this issue, the following measures can be taken:Optimize the material formulation and reasonably control the chemical composition, such as carbon and manganese content.Optimize the heat treatment process by establishing appropriate heating and cooling systems to achieve good low-temperature toughness.Optimize the coil forming process to reduce potential issues such as cracks and fractures during forming.Reasonable combination of alloying elements, with appropriate additions of elements such as nickel and chromium to improve the toughness and corrosion resistance of the steel plate.In summary, the reasons for the failure of low-temperature impact in Q390E steel are multifaceted and require comprehensive consideration of material formulation, heat treatment process, coil forming process, and alloying element content. By implementing corresponding measures, the low-temperature impact performance of the steel plate can be effectively improved. more>

$1500
Category: Others
Company: Shenzhen Hengxin Hengye Technology Co., Ltd.
Product Description: Flexible Printed Circuit Board, also known as "FPC flexible board", is a printed circuit made of flexible insulating substrate, offering many advantages that rigid printed circuit boards do not possess. For example, it can be freely bent, wound, folded, arranged according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection. Using FPC flexible boards can reduce the volume of electronic products, meeting the needs of electronic products developing towards high density, miniaturization, and high reliability. Therefore, FPC flexible boards are widely used in fields or products such as aerospace, military, mobile communications, laptops, computer peripherals, PDAs, and digital cameras. FPC flexible boards also offer good heat dissipation and solderability, are easy to assemble, have relatively low comprehensive costs, and the combination of rigid and flexible design to some extent compensates for the slight deficiency of flexible substrates in component carrying capacity. Flexible printed circuit boards can be single-sided, double-sided, or multi-layered. The substrate used is mainly polyimide copper-clad laminate. This material has high heat resistance and good dimensional stability, and is pressed together with a cover film that provides both mechanical protection and good electrical insulation to form the final product. The surface and inner layer conductors of double-sided and multi-layer printed circuit boards achieve electrical connection between inner and outer layer circuits through metallization. The functions of flexible circuit boards can be divided into four types: lead lines, printed circuits, connectors, and multi-functional integrated systems, with applications covering computers, computer peripheral auxiliary systems, consumer appliances, and automobiles, among others. FPC flexible boards (1) can be freely bent, wound, folded, arranged according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection; (2) using FPC can reduce the volume and weight of electronic products, meeting the needs of electronic products developing towards high density, miniaturization, and high reliability. Therefore, FPC flexible boards are widely used in fields or products such as aerospace, mobile communications, laptops, computer peripherals, PDAs, and digital cameras; (3) FPC flexible boards also offer good heat dissipation and solderability, are easy to assemble, have relatively low comprehensive costs, and the combination of rigid and flexible design to some extent compensates for the slight deficiency of flexible substrates in component carrying capacity. FPC flexible boards have many advantages such as space saving, weight reduction, and high flexibility, and the global demand for flexible circuit boards is increasing year by year. The characteristics of flexible circuit boards make them a replacement for rigid circuit boards and traditional wiring solutions in many situations, while also driving the development of many new fields. The fastest-growing part is the internal connection lines of computer hard disk drives (HDD), the second fastest-growing field is new integrated circuit packaging, and the market potential of flexible circuit technology in portable devices (such as mobile phones) is very large. more>
