JM-IV abrasive meter

The JM-IV abrasive meter meets the requirements of the GB-4893.4-85 national standard. It is suitable for measuring the wear resistance of wood furniture and other wood products surface paint film. The instrument is characterized by .1) the transmission part uses a non - stage speed control. Can meet different speed requirements; 2) can be different test requirements with different material grinding wheels; 3) placed on the left and right turntables of the two grinding wheels. An abrasive by the center of the surface of an extrode model. Another model center from the outward friction of

. When the turntring rotates for a week. The wear marks on the surface of the model re-consum each other and are X-shaped and intersecting in two rings. So. The surface of the model is abrasive in all directions. Overcomes the defect that the ordinary wear-resistant instrument has only one direction to carry on the recidiving motion and causes the paint film to wear unevenly; Reliable performance.
the test. Add 1000g silicon code to the front of the pressurized arm of the instrument to press the grinding wheel on the sample. The weight is indicated as the weight weight of the weight weight and the weight of the pressurized sleeve itself A (250g) and the balance weight is added to the pin shaft at the end of the pressurized arm. Used to balance the grinding wheel. The weight of the balancing weight is the difference between the weight of the grinding wheel and the weight of the pin shaft (20g) and the sample is then sanded. It's over. Brush off the floats. Weighing weight (accurate to 0.001g). The difference between front and rear weight is paint film weight loss. And observe the paint film surface wear. Evaluate the wear resistance of the paint film. The instrument is also equipped with a grinder. Used to repair rubber grinding wheels. Rubber grinding wheel diameter is less than 45mm. The grinding wheel should be updated.
