Overview CTI-ABT ceramic unglazed tile wear-resistant tester adopts a reduction mechanism based on the principle of cycloidal pin tooth meshing planetary transmission. It has the characteristics of compact structure, smooth transmission, low noise, and constant output transmission speed. ISO 10545-6: 1995 "Test Methods for Ceramic Tiles - Determination of Wear Resistance Depth of Unglazed Tiles", "Test Methods for Wear Resistance of Concrete Pavement Tiles", "Test Methods for Performance of Concrete Pavement Tiles", "Tests on Wear Resistance of Inorganic Floor Materials" Methods" requirements for test instruments. By replacing different grinding wheels, inspections of different standards can be achieved, and one machine can be used for multiple purposes.
It is suitable for wear resistance testing of brittle materials such as ceramic unglazed tiles, mosaics, cement mortar, cement pavement tiles, etc.
Working principle and result evaluation ·The instrument consists of a power transmission part, a sample fixture part, an abrasive storage and supply part and an electrical control part. ·The grinding wheel rotates at a constant speed, and the sample is contacted with the friction steel wheel by applying a pressure weight to a certain pressure. The abrasive enters the grinding area evenly according to the specified flow rate (100g/100r/±10g/100r), and the surface of the sample is made under the action of the abrasive. Grinding pits are produced. ·By measuring the chord length of the grinding pit on the surface of the sample (accurate to 0.5mm), the volume of the grinding pit is calculated to express the wear degree of the sample. Each sample is evaluated based on the average wear volume of two locations.
