  • เพื่อตอบกลับ: Is mustard oil cooling or heating? #317709
    Robert Thomas
    สมาชิก

    In traditional medicine systems like Ayurveda, mustard oil is considered a heating oil, meaning it generates warmth in the body and is used for massages or to improve circulation. In biodiesel production, this “heating” classification has no effect—what matters is the oil’s chemical composition. Mustard oil’s fatty acid profile allows for effective conversion into biodiesel with good combustion properties when processed under controlled conditions using systems like the GlobeCore USB plant.

    เพื่อตอบกลับ: is mineral oil a hazardous material? #314911
    Robert Thomas
    สมาชิก

    Mineral oil, while generally safe for insulation, can be hazardous under improper conditions since it is flammable and may cause environmental harm if spilled.

    เพื่อตอบกลับ: what is bdv in transformer? #314903
    Robert Thomas
    สมาชิก

    BDV stands for Breakdown Voltage—the voltage at which the insulating oil fails to prevent electrical discharge.

    เพื่อตอบกลับ: which type of oil is used in transformer? #314787
    Robert Thomas
    สมาชิก

    As noted earlier, the most widely used oil in transformers is refined mineral oil. It is preferred for its proven performance in electrical insulation and heat dissipation.

    เพื่อตอบกลับ: what is bdv value of transformer oil #314636
    Robert Thomas
    สมาชิก

    The BDV value of transformer oil is the voltage at which the oil fails to insulate against electrical discharge; high-quality oil generally exhibits a BDV of over 30 kV, although the exact value depends on its condition and purity.

    เพื่อตอบกลับ: How is whey separation managed, and what machinery assists in this process? #297641
    Robert Thomas
    สมาชิก

    Whey separation is typically handled using centrifugation or filtration systems that separate liquid whey from the thicker yoghurt curd. While the Colloid Mill GlobeCore is not directly involved in whey separation, its ability to create a uniform emulsion can reduce excessive whey release by stabilizing the milk matrix before separation occurs.

    เพื่อตอบกลับ: How are particles removed from circuit breaker oil? #132284
    Robert Thomas
    สมาชิก

    Particles are removed using filters with varying pore sizes. Coarse filters capture larger debris, while fine filters remove microscopic particles that can affect oil performance.

    เพื่อตอบกลับ: What is FR3 oil cooling efficiency? #132127
    Robert Thomas
    สมาชิก

    It provides superior cooling, reducing the risk of overheating and improving transformer longevity.

    เพื่อตอบกลับ: What makes eco-friendly transformer oil different? #131996
    Robert Thomas
    สมาชิก

    Eco-friendly transformer oils are plant-based, biodegradable, and safer for the environment compared to traditional mineral oils.

    เพื่อตอบกลับ: How does viscosity affect the application of asphalt emulsion? #131356
    Robert Thomas
    สมาชิก

    Viscosity controls flow and application uniformity. Low viscosity is ideal for spraying, while higher viscosity suits mixing with aggregates. Proper viscosity ensures even coverage and prevents clogging of equipment.

    เพื่อตอบกลับ: How do bitumen emulsions differ from traditional bitumen? #131257
    Robert Thomas
    สมาชิก

    Bitumen emulsions are liquid at ambient temperatures due to the dispersion of bitumen in water, allowing for cold application without heating. Traditional bitumen requires heating to become workable. Emulsions are safer to handle, reduce energy consumption, and are used in various maintenance and surface treatment applications.

    เพื่อตอบกลับ: What is Styrene-Butadiene-Styrene (SBS) in bitumen modification? #131152
    Robert Thomas
    สมาชิก

    SBS is a thermoplastic elastomer used as a modifier in bitumen. It enhances elasticity, flexibility, and temperature susceptibility, improving the binder’s performance under varying temperatures and loads, and reducing pavement distresses like rutting and cracking.

    เพื่อตอบกลับ: Which additives are commonly used in bitumen modification? #131126
    Robert Thomas
    สมาชิก

    Common additives are polymers (SBS, SBR, EVA), crumb rubber, polyethylene, polypropylene, nanoclays, carbon nanotubes, fibers, and chemical agents like sulfur. These additives modify the physical and chemical properties of bitumen to improve performance.

    เพื่อตอบกลับ: What are the key bitumen emulsion specifications to consider? #131069
    Robert Thomas
    สมาชิก

    Key specifications include viscosity, residue content, setting time, particle charge, and storage stability. These properties ensure the emulsion’s performance matches the intended application and industry standards.

    เพื่อตอบกลับ: What is a bitumen emulsifier and how does it work? #130929
    Robert Thomas
    สมาชิก

    A bitumen emulsifier is a chemical additive used to stabilize the mixture of bitumen and water in an emulsion. It works by reducing the surface tension between the bitumen droplets and the water, allowing the bitumen to disperse evenly throughout the aqueous phase. Emulsifiers are typically surfactants that can be anionic, cationic, or non-ionic, affecting the charge of the bitumen droplets and influencing how the emulsion interacts with aggregates. The choice of emulsifier impacts the setting time, adhesion properties, and overall stability of the bitumen emulsion.

    เพื่อตอบกลับ: How is quality control maintained during the oil bleaching process? #123258
    Robert Thomas
    สมาชิก

    Quality control during oil bleaching is maintained by monitoring key parameters such as oil color, free fatty acid levels, and impurity content. Regular sampling and testing throughout the process ensure that the oil meets the desired quality standards. Automated systems can also help by providing real-time feedback on process conditions.
