  • YY-DH20L Double-planet vacuum defoaming mixer

    YY-DH20L Double-planet vacuum defoaming mixer

    I. Overview:

    YY-DH20L Double-planet Vacuum Defoaming Mixer is an all-round new model that combines the principles and components of traditional dual planetary mixers and high-speed dispersers. It is currently widely used in many fields.

    Considering the characteristics of high solid content and high viscosity of power slurry, our company has developed an enhanced power mixer with higher rotation speed and larger torque on the basis of the original planetary power mixer. During the design process, factors such as the rotation speed of the agitator, stirring power, dispersion linear speed, suspension level, liquid flow pattern and the distribution of turbulence intensity in the bucket were fully considered. Its maximum high-speed dispersion linear speed can reach 25m/s, and the enhanced folding blade frame can handle any high-viscosity slurry. The new mixing method – the folding blade frame rotates clockwise in revolution and counterclockwise in rotation, ensuring no dead ends in mixing and no “climbing” phenomenon. In terms of sealing, two sets of mechanical seals plus soft and static seals ensure vacuum degree – theoretically, the sealing performance is enhanced by 30%. The Pt100 temperature sensor is in direct contact with the material, resulting in more accurate measurement and faster response speed, with an error of only ±0.5℃. This machine is composed of a base, beam, column, sealing cover, material cylinder, transmission and electrical control system.

  • YY108D Pneumatic Tear Tester

    YY108D Pneumatic Tear Tester

    Instrument Description:

    YY108D Pneumatic Tear Tester is designed to measure the force required to tear a certain number of pre-notched sheets, such as paper, plastic films, polymer materials, and non-woven fabrics. The instrument adopts an optical encoder to measure the angular position of the pendulum during tearing and converts this measured value into tearing units. It is suitable for determining the tearing resistance of various types of paper and can also be used for testing the tear resistance of low-strength sheet-like composite materials such as textiles, leather, and films. It is widely applied in paper mills, scientific research institutions, and quality inspection departments.

    Working Principle:

    A stack of test samples with specified pre-notches (usually 4 layers) is clamped. The pendulum is lifted to a certain height to accumulate a specific amount of potential energy. When the pendulum swings freely, it uses its stored energy to tear the sample over a fixed distance. The work done in tearing the sample is measured by the loss of potential energy of the pendulum.

    Executive Standards:

    GB/T 455, QB/T 1050, GB/T 16578.2, ISO 1974, TAPPI T414, ISO 6383-1, ISO 6383-2, ASTM D1922, ASTM D1424, ASTM D689
