CaSi

Silicon calcium alloy is a composite alloy composed of silicon, calcium and iron. It is an ideal composite deoxidizer and desulfurizer. Silicon alloy not only has strong deoxidation ability, but also deoxidized products are easy to float and discharge, but also can improve the properties of steel, and improve the plasticity, impact toughness and fluidity of steel. Currently, calcium-silicon alloys can replace aluminum for final deoxidation. It can also be used as an inoculant for cast iron and an additive for the production of ductile iron.

Specifications: Natural block, 10-100mm, 10-60mm, 3-10mm, 1-3mm, 0-1mm or customized according to customer requirements.

APPLICATION
The use of tobermorite as a filler for papermaking. In the present invention, 40%-60% of plant pulp fiber raw material is used as the skeleton, 40%-60% of tombstone is used as papermaking filler, and water-soluble high molecular multipolymer is used as reinforcing agent. filler paper. Compared with the existing paper-making method, the present invention uses tobermorite as the paper-making filler, and the phenomenon of "powder-dropping" of the filler on the surface of the paper will not occur during the paper-making process, and the retention rate of the filler after the paper machine is on the Internet is generally average. At 55%-85%, the retention rate of fillers in traditional papermaking is 20%-50% higher than that of traditional papermaking fillers, which effectively reduces filler waste; the paper made by the method of the present invention has low elongation, high opacity, high smoothness, no Pollution, degradable, recyclable, low cost and other advantages.
