Detailed Description

Characteristics: 1. Stable thermal capability 2. Excellent friction coefficient 3. Low abrasive, low noise, low shot content 4. No static-formed sphere, easy to open Application Range: It is one of the raw materials of producing brake pad, brake tile, cluth and other automotive parts in car industry Advantage: 1. Excellent thermal capability and low thermal conductivity 2. High-purity fiber 3. Coincident chemical component Technical Index: Ceramic Clean Fiber Villus SDTR SDKR Color White/Gray White/Gray Length 150-200um 150± 20um Diameter 3-5um 3-5um Shot content <8% <8% Using temperature 1000 degree 1000 degree Tensile strength 1400-1600/MPa ------ Mor's hardness 5-6 5-6 Density 260kg/m3 260kg/m3 SiO2+AL2O3 ≥ 96% ≥ 96% AL2O3 44% 44% FE2O3 ≤ 1% ≤ 1% Method of Application The main step by using the SDTR or SDKR ceramic fiber villus in the formulation is to open the ceramic fiber in advance. Sufficient fiber opening is a key factor in the processing. Wet-processing is easy to open the ceramic fiber villus, usually put it in the mixed material at later stage. The recommend blender mixer by putting the mixed material in dry method is: Vertical type, high speed stirring mill, pear rake type blender mixer or other opening stirring mills. Favorable opening effect also dependent on other material in the formulation. Please refer to the method during the opening as follows: 1. Change the mixing material in dry-method from 1 time to 2 times. At the beginning of mixing material, add some high proportion filler, such as metal fiber, barium sulfate etc. Then add other material after stirring it about 2-3 minutes in order to reach the desired effects. 2. Please reduce the metal fiber usage amount at the first stage. Because more metal fiber usually make the fiber snarling, so the mixed material can not reach to desired effect. 3. Lowering the stirring mill load. If there are a lot of raw material in the stirring mill, the machine will be under great load, the reamer can not make the material fully split-flow. It will influence the opening effect. 4. Proper extending the time of mixing material, usually from 3-4minutes, but time should not be too long to make the fiber ball hardening. 5. Ceramic fiber matching usually decided by different variety, recommend dose of material is from 5~9%.
