RisingSun Factory Direct Sales Flat Sheet Membrane Acid and Alkali Resistant Membrane Full Amount Free Shipping
Technical Parameters
SA Series Acid Resistant Membrane
Prepared with modified polyethersulfone and other acid-resistant materials, it can withstand strong acid (pH 0-2) environments. The membrane surface is smooth, not easily corroded by acid, with high mechanical strength and long service life. The pore size distribution is uniform, with high separation precision, enabling effective separation of small molecule organics and ions.
Separation Performance: It can still maintain stable separation efficiency and operating flux in high-concentration strong acid systems, suitable for separation, purification and concentration needs of various acidic materials.
Typical Applications
20% Sulfuric Acid, 20% Hydrochloric Acid, 30% Phosphoric Acid, 15% Acetic Acid, 4% Nitric Acid
SC Series Alkali Resistant Membrane
Product Features
RisingSun alkali resistant membrane adopts modified polyethersulfone and other special alkali-resistant materials, which can withstand strong alkali (pH 12-14), and even high-concentration alkali environments not characterized by pH. The membrane surface is corrosion-resistant and has high mechanical strength. The pore size distribution is uniform, with high separation precision, effectively separating small molecule organics and metal ions, with excellent rejection rate performance.
Typical Applications
≤20% Sodium Hydroxide, ≤10% Potassium Hydroxide
To meet the different needs of customers, RisingSun can provide ultrafiltration, nanofiltration, microfiltration and reverse osmosis membrane sheets of various materials and molecular weight cut-offs. For the acid-alkali recovery industry, our company can provide membrane sheets resistant to 20% NaOH concentration, with good chemical stability, long service life and high separation efficiency.
