Product Description
1. Performance andApplications
Q875D is composed of polymer surfactants and fatty acid esters. It is resistant to high temperatures and strong acids, with significant defoaming and foam suppression effects. It is widely used in the extraction of phosphoric acid from phosphate rock using sulfuric acid, hydrochloric acid, and nitric acid, as well as in the desulfurization of feed-grade phosphates and in the foam suppression during the production of titanium dioxide. It requires a small amount, acts quickly, and is environmentally friendly.
