microsilica coal【价格 厂家 供应】-pg电玩城

coal and microsilica is the product introduced by our company in order to solve the problem of using microsilica to drill cans during cementing, resulting in increased cementing transportation cost, and to improve and reduce the workload and working environment of ash loaders. different grade of microsilica, fly ash and dry strength agent are used to make low density external admixture of different specifications. through the regulation of coal and microsilica products of different specifications, our company has developed 1.25~1.55g/ cm cubed slurry irrigation system of different densities:

the low-density cement slurry system has a wide range of uses. according to the requirements of different customers, our company can be divided into three products of different specifications: a, b and c. in recent years, through the use of our coal and microsilica products to adjust the cement slurry system to ensure the stability of the slurry, the slurry production rate increased, and the strength significantly increased. the cementing quality is guaranteed.

microsilica (or silica fume) is amorphous, powdered sio2 collected by specially designed dust collectors after the oxidization of silicon steam through smoke flue during the smelting of silicon iron and industrial silicon. the average particle size of microsilica is 1% of the average particle size of cement at a value of 0.1-0.15 m. the specific surface area is 15-27 m2/g, with strong surface activity.

according to the sio 2 content index, our products are divided into five specifications: 85%, 88%, 90%, 92% and 95%.
