Sulphonated Asphalt *

RODUCTS TECHNICAL DATA

PRODUCT NAME :Sulphonated Asphalt, ME-ASPHASOL

COMPOSITION / INFORMATION ON INGREDIENTS AND APPLICATIONS

Sulphonated Asphalt,ME-ASPHASOL is an acid soluble and water soluble. High purity Sulphonated asphalt product is made by solvent full sulfonation. 

Sulphonated Asphalt Sulfonic acid of asphalt + NaOH → Sodium asphalt sulfonate;

Sulfonic acid of asphalt + KOH → Potassium asphalt sulfonate .

Compared with ordinary modified asphalt, its molecular chain itself contains many adsorption groups, which can be effectively plugged on the surface of shale by electrical adsorption. It is not affected by formation temperature and asphalt softening point. can be well dispersed in various water-based drilling fluids, which can effectively inhibit the hydration of drilling debris and stabilize the cutting force of drilling fluid; Good plugging effect, can greatly improve the quality of mud cake, temperature resistance 200℃, effectively control high temperature and high pressure filtration loss; giving particles that are relatively coarse and quite narrow in particle size distribution. Sulphonated Asphalt being a Sulphonated/reacted material, has a wide range of particle sizes ranging from soluble to colloidal to the size one would expect from ground materials. This wide range of sizes provides a high probability of having the proper particle size to fit into the variety of fracture sites. Virtually all ME-ASPHASOL additive particles, regardless of size, are highly anionic.
