    Homogenization reduces fat globules and evenly disperses milk solids, leading to a smoother, more stable product. The Colloid Mill GlobeCore, with its high-shear rotor-stator design, refines the milk further, ensuring a consistently fine emulsion that improves both mouthfeel and shelf-life.

    in reply to: Why is OLTC oil filtration important? #132494
    Brian Allen
    Member

    Oil filtration in on-load tap changers (OLTC) is crucial for several reasons: it maintains the dielectric strength of the oil, preventing electrical breakdown; it removes particulate contaminants that can cause wear and damage to contacts; it reduces moisture levels, which can lead to corrosion and insulation failure; and it enhances the overall reliability and lifespan of the OLTC. Regular oil filtration helps ensure optimal performance, minimizes maintenance costs, and prevents unexpected failures in transformer operation.

    Antistripping agents are additives that enhance the adhesion between bitumen and aggregates, reducing moisture-induced damage (stripping). By improving the bond, they prevent water from weakening the pavement structure, thereby increasing durability and extending the asphalt’s service life.

    in reply to: How is fatigue resistance tested in asphalt pavements? #131239
    Brian Allen
    Member

    Fatigue resistance is tested using laboratory methods like the four-point bending beam test, indirect tensile fatigue test, or using an Asphalt Mixture Performance Tester (AMPT). These tests simulate repeated loading to determine how many cycles the asphalt can withstand before cracking, reflecting its durability under traffic loads.

    in reply to: What are the characteristics of cationic bitumen emulsion? #131044
    Brian Allen
    Member

    Cationic bitumen emulsions contain positively charged bitumen droplets stabilized by cationic emulsifiers. They are known for their rapid setting and strong adhesion to a wide range of aggregates. Characteristics include good coating ability, even at lower temperatures, and compatibility with moist aggregates. Cationic emulsions break upon contact with the aggregate surface, facilitating quick curing. They are widely used in surface dressing, tack coats, and cold mix applications where fast setting and strong bonding are required. Their versatility makes them popular in various climatic conditions.

    in reply to: How much time is needed for silica gel regeneration? #123766
    Brian Allen
    Member

    The time needed for silica gel regeneration typically ranges from 2 to 3 hours when using an oven at 120-150°C. The exact time depends on the amount of silica gel and its initial moisture content. For more extensive or frequent needs, GlobeCore’s equipment can automate the process, offering consistent drying times through precise temperature control. This makes it possible to manage larger volumes of silica gel effectively, ensuring that the regenerated silica gel is ready for use without delays.

    in reply to: How is Midel oil used in substation transformers? #123398
