Application of Abrasive Powdering Rate in the Detection of Brown Fused Alumina

Author:Jinlin corundumTo update: 2016-10-09

During the National Day, the internet appeared on a “Yangtze River goddess – baiji appeared” report, suddenly caused a lot of hot,the Chinese academy of sciences also said white baiji in “functionally extinct”.With the development of our economy, the destruction of the environment, there are many animals on the verge of extinction.Actually not only animals, and many things are gradually reducing, but we didn’t notice carefully.
China’s bauxite resources are gradually reduced, many enterprises in order to reduce the cost of brown fused alumina smelting, choose jerry-building, so the use of brown fused alumina, its hardness and toughness is less than the grinding effect required, This is also one of the reasons that we said that obstacles to the development of brown fused alumina abrasives. In order to reduce the purchase error, we will now introduce one of the most simple detection method – application of abrasive powdering rate in the detection of brown fused alumina.
I think many people will have questions: how to determine the rate of abrasive powder? Determination of abrasive powder particle size is based on different particle size in different temperature conditions, the ratio of powder to determine the difference, so the same particle size can only be at the same temperature and the same firing time for comparison, the different particle size abrasive required temperature is not the same, so there is no comparable. Specific testing methods are as follows:

%e6%a3%95%e5%88%9a%e7%8e%89%e8%8b%b1%e6%96%87
1. Take brown fused alumina sample 200 grams in a 105-degree drying oven for one hour, remove the room temperature reserve;
2. Will be 200 grams of sample size and number on the line in the screening test, screening for 10 minutes, remove the basic mesh products in the mesh, and then the original method of screening materials for 5 minutes, take the basic mesh Material reserve;
3. The screening of good materials accurately weighing 100 grams on the high-temperature containers;
4. The furnace will be adjusted to the required temperature, the material into the high-temperature furnace, firing time 1 hour;
5. After the firing of the material taken out to room temperature standby;
6. The sintered material after the screening test with the standard sieve for 5 minutes, weighed the basic mesh of the number of materials.
The above is our company for abrasive powder in the brown fused alumina detection application of the overview, if we want to maximize the use of brown fused alumina to play out, we have to learn this method, although seemingly cumbersome but it is the most effective of. Do not say why the price of brown fused alumina is higher than black fused alumina, because smelting process and classification of brown fused alumina are very tedious.
