From wood pitch receive also inhibitores oxidations fuels and oils.
Pitch wood saponated
(TU 2453-013-10644738-00), (the liquid additive in concrete)
The additive – liquid pitch wood saponated(SDО), received by a way saponated wood pitch is developed and introduced by alkali in manufacture of all kinds of concrete air-entraining and plastisizing.
Additive SDО represents a liquid of dark brown colour 50-55 %-s' concentration, concerns substances low-hazard does not render poizonous action on an organism and irritating action on a skin and mucous, is not explosive, not fire-hazardous. The product is delivered to the consumer in railway tanks or metal flanks. The working solution of the additive prepares simple thinning the quantity of a concentrate measured on volume a settlement quantity of water with simultaneous hashing. Expense SDО is in limits of 0,1-0,25 % from the cement expense counting on an additive solid.
It is applied in quality:foaming ahent, plasticizing, air-entraining, the cold-resistant antiseptic additive.
For preparation of concrete of different function: foam concretes, polystyrene foam, cellular, hydraulic engineering, heavy, road, easy and others.
Application liquid SDО will allow the enterprises:
Price of liquid additive SDО are considerable below cost of other additives of similar appointment.
