PromFilter Ltd

DESIGNATION: High Silicon Fiberglass Filters are designed for fine filtering both liquid irons (gray east irons, malleable cast irons, ductile cast irons) and non-ferrous metals while sand mould and chill mould casting.
DE
SCRIPTION: Our Filters are made of silicon fiberglass ?KS-11-LA?, which rigidness is obtained by special weaving of silicon fibre (NOT BY THE COATING). Further woven fiberglass is impregnated with special substance to get required properties - ensuring the short-term heat resistance in liquid metals up to 1700 ?C. The surface density is 450 - 500 g/m2. Filters are made with two types of cells: 1,5x1,5 mm; 2,0x2,0 mm. According to the customers desire they can be delivered in the roles of 0,8 m width and up to 50 m length. They can also be delivered ready-made for the placement directly in the mould with dimensions in any range from 50 mm to 300 mm in form of square or rectangular.
ADVANTAGES:
1. The structural silicon fibres of our filters are
not glued one to another, they are weaved to reach the Filter?s rigidness.
2. The weaving has allowed us not to use toxic
and gas forming components for our Filters coating (phenolformaldehyde and organic cohesives).
3. Possibility for use of se
veral components for coating, that helps to modify the structure and other properties of metallic mould and also insures refinable, additional graphitizing (for irons), modificatory effects.
4. High heat resistance ? up to 1700 degrees C.
