Molecular formula :
CAS :
nature : sexual known as wear and tear resistance. The wear-resistant material properties, wear or use index Wearable said. Almost wearability and materials all have properties, in different Wear conditions, the right to improve the wear resistance properties have different requirements. As the friction material and test conditions of the same can be said or abrasion index used by the wear test machine under conditions measured by the test material reductions (g/cm2), or its countdown, abrasion and wear test of a measurement parameters. Coatings Industry middle mechanical friction coating on the role of resistance. Actually coating hardness, adhesion and cohesion combined effect of the expression. In the same conditions, superior wear-resistance metal coating materials, as a viscoelastic effect, the energy buffer, absorbing and releasing swap. Wear-resistant coating is usually measured wearability. In a certain load, coating with a rubber wheel on the turn after a few grinding, and seek the coating weight loss, expressed in grams. Rubber withstand paper, sandpaper and similar objects friction role durability also said wearability. Characterization of the surface hardness of paper. Through this nature in the load and mobile rate, a standard friction materials friction paper, paper weight loss rate to show. Some hope that the surface hardness of paper such as writing paper and carton board, the general use of starch or plastic material for surface treatment.
