(3)Usage Instructions
Sulfonic acid group-modified cellulose nanocrystals are needle-like nanomaterials obtained by acid treatment of natural plant cellulose.The surface contains sulfonic acid groups, dispersing well in water at PH=1~14. Fiber diameter is 5~10nm, length 100~500um.Due to the unique properties of cellulose and its crystal structure, it exhibits amphiphilicity, stabilizing emulsions by existing at the oil-water interface. It also has strong thixotropy, with a thixotropic index adjustable between 5~12, while having minimal impact on system viscosity after addition.
Dispersion Method:
Pre-disperse the powder into a high-concentration colloid at high speed, mix with the product, and stir and disperse using conventional equipment.
