PH 8 - 10 Coal Tar Chemicals Powder , Strong Hydration Bituminous Coal Pitch Material

High Quality Coal Tar Pitch Bitumen Powder Bituminous Coal Used As Adhesive From China

Sulfonated asphalt powder because of containing sulfonic acid, sulfonated asphalt hydration is very strong, when adsorbed on the interface of shale, shale hydration dispersion of particles can prevent collapse prevention effect. At the same time, part of insoluble in water and filling pore and fracture plugging effect, and can be covered in the shale interface, improve the quality of mud cake. Sulfonated asphalt in drilling fluid lubrication and reduce the amount of high temperature and high pressure filtration effect, 1 is a kind of leak, collapse prevention, lubrication, drag reduction, and inhibition of multifunctional organic drilling fluid treatment agent. 2, lubrication drag reduction, reduce drilling tool lifting capacity and distance longer bit life, prevent and remove sticking; 3, the formation of thin and tough mud cake strengthen the wall. High temperature control water loss; 4, control of mud high temperature shear strength; 5, can be used with other mud treatment agent distribution. Recommend to add 1-6%.
