condensed silica fume

Silica fume is one kind of by-product which collected when produce the ferro silicon and silicon metal, generally the collected silica fume will be in very small density around 150-200kg/m³,the surface area is large around 15000-27000㎡/kg, so this means it will need much more shipping cost, for the package of 150-200kg/m³will be 200-300kg per jumbo bag, then the 40HP container can just load 9-12t, according to the sea cost 1000 dollars per 40HP, the sea cost will be around 83 dollars per ton. Because of this so it will need the condensed silica fume, this will need the Encryption device, and because of the different fluidity the condensed can even reach 700-800kg/m³.

The condensed silica fume can be also called densified silica fume, compared with the silica fume can reduce the shipping cost, it can load 1000kg per jumbo bag, then the 40HP container can load 27-28t, then if the cost is 1000 dollars per container, the sea cost will be 27 dollars per ton. For the other hand, different condensed silica fume may mean different usage, generally the silica fume can be used as the additive of concrete, what is more, it can also be used into the refractory. When used in the refractory it will generally need the fluidity of the silica fume, for the silica fume which condensed, the fluidity can reach 22cm (fluidity refer to dropping a fixed mass of silica fume from a height of one meter and measure the maximum distance that is diffused). When used in the concrete, it always need the volcanic ash activity (it is generally a percent data after seven days in China), the condensed silica fume can reach 125% after seven days.

The qualified silica fume will consist the SiO2 more than 85%, what is more, there are also the 90%,92%,95% etc, condensed silica fume do not limited to some certain purity, all purity can condense, and for the all-condensed type, the shape will be like the spherical, then will with high fluidity.

No matter you need the condensed or un-condensed types, Anyang Huatuo can all meet your requirement, and we would like to help to solve any problems or confused for anyone interested in the silica fume.
