Aluminium Oxide Grit 24 Mesh Suppliers Thailand

Corundum casting prefabricated parts, thickness of 150 mm, burst when baking, without explosion-proof fiber, aggregate is 120 grit aluminum oxide harbor freight, powder is 325 white corundum, aluminum oxide powder, binder is PA80 cement, what's the reason, please comment. How to make the baking curve? your problem is that the raw materials are all electric melting materials, which are not conducive to thermal shock.

You should consider part of the sintered plate-shaped 220 grit aluminum oxide blast media. In addition, the heating speed should not be too fast, and then add water-soluble explosion-proof fiber. Whether the baking temperature rise curve is too fast! Especially during 80- 110 degrees! Considering the activity of alumina powder or ca-80 cement other: adding less explosion-proof fiber can only prevent 46 grit aluminum oxide cracks to a certain extent.(aluminium oxide grit 24 mesh suppliers thailand)

The above points should be solved. exclude whether the white fused alumina aggregate is powdered due to too much carbon residue (whether the castable is thick and smelly after adding water), for the corundum prefabricated parts, first consider the following points: whether the brown fused alumina manufacturer aggregate has too much carbon residue after removing the mold, whether the natural drying or natural curing time is long enough?

(aluminium oxide grit 24 mesh suppliers thailand)Remove the above four points one by one to find out the problem. I think there are the following points for reference: low cement combined with 80 grit aluminum oxide blasting media prefabricated parts, due to the relatively dense materials and large density of construction body, we should pay attention to the explosion-proof performance of low density white alumina products, such as adding 80-90 degree water-soluble organic fiber, air entraining agent, etc.

At the same time, there are many white aluminum oxide involved in grinding and processing, which can be made into quick drying and quick drying products. Corundum particles are too high in residual calcium oxide due to carbon residue; there will be pulverization after adding water during construction, and there will be explosive phenomenon during white fused alumina suppliers baking. Raw material selection quality is the most critical!

(aluminium oxide grit 24 mesh suppliers thailand)Low price and poor quality materials must not be used, otherwise it will affect the whole product and cause failure! For free 100 grit aluminum oxide media abrasive grinding, cracks or explosions appear in the baking, the size of aluminum oxide blast media 60 grit cannot be completely consistent. The difference of thermal expansion coefficient among three phases will also cause cracks among grains during heating.

In addition, if too much titanium oxide (TiO2) is found in the white fused alumina manufacturer, it can not be retained in the glass phase, but react brown fused aluminium oxide to form aluminum titanate (TiO2 (Al2O3)). Aluminum titanate is the third phase at the interface between α - alumina grains and glass phase, which will weaken the glass phase between α - alumina grains. Titanium dioxide mostly exists as a solid solution of α - alumina grains. 

(aluminium oxide grit 24 mesh suppliers thailand)The ratio of TiO2 to SiO2, which is acceptable in typical 1200 grit aluminum oxide technical conditions, is from 2.5:1 to 6:1. During the reduction process in the furnace, part of TiO2 is reduced to titanium oxide (Ti2O3). It is necessary to pay more attention to the proportion of titanium dioxide and alumina in the melting mixture so as to keep it in a position to produce white fused alumina price meeting the technical conditions.
