Measurement of silica fume?s mobility Technology Articles | April 17, 2012 Mobility of silica fume is related with silicon content, but it is out of the proportion. For the same kind of silica fumes, some have good liquidity, while some simply do not have the liquidity.
For testing Air Max 90 97 Kopen , the dispersant must be added. If trimeric sodium phosphate does not work, P530 is available. If both of them do not work, the silicon powder can not be used in the refractory industry.
Simple approach can be used without encryption silica fume, 40 g water, 60 g of silica fume and 0.2 g of dispersant (trimeric or P530). Stir dumping the glass, the natural flow http://www.airmax90kopengoedkoop.com/ , measuring flow area, if the average diameter greater than 150mm while liquidity is generally good, it is best to try to amorphous specimen test, the final judgment according to the amount of water mobility is good or bad. China's micro-silica fume rarely meets this standard. For the encryption of silica fume, can not use the above method only with the amorphous sample to be determined.
Amorphous specimen, the mobility of the detection of micro-silica fume Goedkope Air Max 90 , can easily determine a ratio, such as bauxite aggregate and powder can be used the following proportions: 5-3MM 40% of the bauxite aggregate, 3-1MM 13 %, 1-0MM 15%, 20% of 180 mesh alumina powder, aluminum cement 7% Air Max 90 Bestellen , 5% of silica fume, trimeric 0.15% or trimetric 0.07% six partial 0.05%.
Will be a good raw material weighing, add the dry mix in the mortar mixer, then stir adding 6% water, and then stirred for three minutes, look at the consistency of the mixture. If a more dilute Air Max 90 Nederland , liquidity is good, and then proves that the quality of silica fumes. Such as flow, can appropriate to add a little water to determine the water demand how much. But mere experience judgment for accurate, you need to choose a better mobil
