The price per litre of bitumen emulsion depends on raw materials, formulation, and production scale. GlobeCore plants help producers reduce costs through energy-efficient processing and automation while maintaining top product quality.
Natalie DupontMembreThe GlobeCore TOR-7 cost depends on configuration, but it reduces costs by replacing multiple testing devices and preventing transformer failures.
juillet 23, 2025 à 6:53 am en réponse à : How to test Midel 7131 transformer oil with a universal tester? #321961Natalie DupontMembreUsing GlobeCore TOR-7, you can quickly measure moisture, particle contamination, breakdown voltage, and dielectric losses in Midel 7131 oil on-site or in the lab.
juillet 23, 2025 à 6:49 am en réponse à : How to test mineral transformer oil with a universal tester? #321958Natalie DupontMembreThe easiest way is using GlobeCore TOR-7, which performs multiple tests — including moisture, particle contamination, breakdown voltage, and tan delta — all in a single device.
avril 6, 2025 à 6:49 am en réponse à : What economic and environmental factors affect the large-scale viability of biodiesel production from mutton fat? #317881Natalie DupontMembreEconomically, mutton fat biodiesel benefits from low feedstock cost (when regionally available), renewable energy incentives, and byproduct utilization. Challenges include variable fat quality, transport logistics, and cold-weather limitations. Environmentally, converting mutton fat reduces waste, methane emissions, and reliance on food crops. The GlobeCore USB plant supports modular scalability, allowing producers to start small and expand with demand. Regulatory compliance, sustainable sourcing, and energy efficiency are key for long-term viability in large-scale applications.
avril 5, 2025 à 11:13 pm en réponse à : Which catalysts or processes are most effective when converting beef fat with potentially high free fatty acid content into biodiesel? #317845Natalie DupontMembreIf the FFA content exceeds 2–3%, a two-step process is preferred: 1) Acid-catalyzed esterification using sulfuric acid to lower FFAs, followed by 2) Base-catalyzed transesterification using NaOH or KOH. This prevents soap formation and ensures high biodiesel yield. The GlobeCore USB biodiesel plant supports both stages with automated dosing and reaction control, allowing reliable conversion even with raw or low-grade tallow. For low-FFA tallow, base-catalyzed transesterification alone is sufficient.
Natalie DupontMembreSunflower oil is converted into biofuel through a process called transesterification, where the oil reacts with methanol and a catalyst (like sodium hydroxide). This separates glycerin from the fatty acid chains, forming biodiesel. Using the GlobeCore USB biodiesel production plant, the process is automated and optimized for speed, safety, and fuel quality. The unit handles mixing, heating, reacting, and separating, reducing labor and ensuring compliance with EN 14214 and ASTM D6751 fuel standards. It’s an ideal solution for farms, co-ops, or businesses looking to turn sunflower oil into usable fuel.

Natalie DupontMembreA marine power transformer is a specialized electrical device designed to transfer electrical power efficiently and safely between circuits in marine environments. It is engineered to withstand harsh conditions, such as saltwater exposure, humidity, and temperature variations, ensuring reliable operation on ships.
Natalie DupontMembreMobile plants are skid-mounted units designed for on-site production. They include compact storage, dosing, and mixing systems, allowing for flexibility and quick deployment.
novembre 21, 2024 à 4:17 pm en réponse à : How are bitumen emulsion plants customized for specific outputs? #131520Natalie DupontMembrePlants can be customized with capacity-specific tanks, specialized emulsifier systems, and automation levels tailored to production needs, ensuring efficiency and product consistency.
novembre 21, 2024 à 1:08 pm en réponse à : How does storage tank design impact bitumen emulsion quality? #131508Natalie DupontMembreProperly designed tanks with insulation, agitation systems, and temperature controls prevent sedimentation and maintain homogeneity. Clean tanks reduce contamination risks, preserving emulsion quality.
novembre 21, 2024 à 12:12 am en réponse à : How is the Bending Beam Rheometer (BBR) used in bitumen analysis? #131331Natalie DupontMembreThe BBR assesses low-temperature properties by measuring the flexural creep stiffness of a bitumen beam specimen at low temperatures. It provides parameters like creep stiffness (S) and m-value (rate of stiffness change), indicating the binder’s ability to resist thermal cracking by absorbing stresses through deformation without fracturing.
novembre 20, 2024 à 2:39 pm en réponse à : How is asphalt emulsion spray applied effectively? #131231Natalie DupontMembreAsphalt emulsion spray is applied using calibrated distributor trucks or spray equipment to ensure even coverage. Proper nozzle selection and pressure settings are critical for effective application.
novembre 19, 2024 à 9:23 pm en réponse à : What asphalt emulsion standards are commonly followed in the industry? #131059Natalie DupontMembreStandards like ASTM D977 (anionic emulsions) and ASTM D2397 (cationic emulsions) are widely used. AASHTO and EN standards also provide guidelines for testing, classification, and performance requirements, ensuring quality and consistency.
Natalie DupontMembreBitumen emulsion is a mixture of fine droplets of bitumen and water. It is a liquid form of bitumen, making it easier to handle at lower temperatures compared to traditional hot bitumen. The emulsion is stabilized by adding an emulsifying agent, which prevents the bitumen droplets from coalescing. Bitumen emulsions are widely used in road construction and maintenance, including surface dressing, tack coats, and cold mix applications. They offer advantages such as reduced energy consumption, lower emissions, and safer handling due to lower application temperatures.
