juillet 23, 2025 à 9:26 am en réponse à : What is the fastest way to test Midel 7131 transformer oil? #322025David LeeMembre
The fastest way is using GlobeCore TOR-7, which delivers all key test results in minutes, minimizing transformer downtime during servicing.
juillet 22, 2025 à 5:44 pm en réponse à : Portable diesel fuel moisture and particle tester price #321868David LeeMembreThe cost of GlobeCore TOR-6 testers varies by model and configuration, but they help avoid equipment failures and maintenance costs due to contaminated diesel.
avril 5, 2025 à 6:44 am en réponse à : Which chemical catalysts or techniques are most effective for converting olive oil to biodiesel? #317755David LeeMembreSodium hydroxide (NaOH) and potassium hydroxide (KOH) are the most effective catalysts for olive oil due to its low FFA content. Base-catalyzed transesterification works best, eliminating the need for acid pre-treatment. The GlobeCore USB biodiesel unit automates catalyst dosing and reaction control, achieving efficient conversion, even from lower-grade or waste olive oils, ensuring fuel quality and stability.
David LeeMembreYes, peanut oil qualifies as a biofuel feedstock. While not commonly used in its raw form due to high cost and viscosity, it is excellent for biodiesel production through transesterification. The resulting biodiesel offers clean combustion, good lubricity, and high cetane numbers. When processed with the GlobeCore USB plant, peanut oil yields a high-quality, renewable fuel compatible with diesel engines, contributing to energy diversification and reduced environmental impact.
David LeeMembreFuel from coconuts can be made in two main ways: from coconut oil (biodiesel) or coconut shell (biochar or syngas). For biodiesel, oil is extracted, filtered, and reacted with methanol and a catalyst. The GlobeCore USB system performs this with automation and precision, producing fuel for diesel engines. Coconut shells can also be converted into energy through pyrolysis or gasification. These methods provide renewable energy options from both oil and biomass components of the coconut.

David LeeMembreThe dielectric dissipation factor (tan delta) measures energy losses in an insulating material when exposed to an electric field, indicating insulation quality.
David LeeMembreMineral oil is used in transformers because it offers excellent dielectric properties, efficient thermal conductivity, and cost-effective performance.
mars 6, 2025 à 5:33 pm en réponse à : What therapeutic advantages do pharmaceutical pastes offer compared to creams or ointments? #314515David LeeMembrePastes offer superior adherence, longer residence time, reduced irritation, enhanced barrier properties, and controlled drug release compared to creams and ointments. GlobeCore Colloid Mills significantly contribute to these advantages through consistent particle size control and product uniformity, optimizing therapeutic effects.
David LeeMembreA transformer is an electrical device that transfers energy between circuits by electromagnetic induction, commonly used to step up or step down voltage levels.
David LeeMembreControl systems automate tap-changing operations based on voltage levels, using sensors and relays to ensure consistent output.
David LeeMembreStore oil in sealed tanks, avoid exposure to sunlight, and monitor temperature levels. GlobeCore tanks provide advanced features for safe storage.
novembre 21, 2024 à 9:31 pm en réponse à : How are bitumen emulsion spray systems calibrated for accuracy? #131540David LeeMembreCalibration involves setting flow rates, adjusting nozzle angles, and testing spray patterns to ensure even coverage and proper application rates in the field.
novembre 21, 2024 à 5:17 am en réponse à : How does asphalt emulsion contribute to energy savings in paving? #131383David LeeMembreAsphalt emulsion is applied at ambient or lower temperatures, eliminating the need for heating and reducing fuel consumption. This results in significant energy savings during production and application.
novembre 19, 2024 à 2:04 pm en réponse à : Why is emulsion quality control crucial in asphalt production? #131030David LeeMembreQuality control ensures the emulsion meets specifications, providing consistent performance and durability. It prevents issues like poor adhesion, uneven application, or premature breaking. Regular testing improves reliability, reduces costs, and enhances pavement longevity.
novembre 19, 2024 à 8:00 am en réponse à : What is an emulsion tack coat and when is it used? #130921David LeeMembreThe thickness of an emulsion tack coat typically ranges from 0.1 to 0.3 gallons per square yard, which translates to a film thickness of about 0.5 to 2 mils (15 to 50 microns). This thin application is designed to create a bond without adding significant weight or thickness to the pavement structure. Proper calibration and application techniques are essential for achieving the desired coverage and effectiveness.
octobre 7, 2024 à 6:28 am en réponse à : What is the latest technology in fuel oil polishing? #122574David LeeMembreRecent advancements in fuel oil polishing technology include automated systems with real-time monitoring and diagnostics, as well as improved filtration methods like centrifuges and advanced multi-stage filters. Automated systems can detect fuel contamination early and adjust operations to optimize purification. Other innovations include mobile polishing units for flexibility and enhanced water separation techniques to ensure cleaner fuel in shorter processing times.
