Jiangsu Hengfeng has become a professional production and research and development base for water treatment chemicals and oilfield chemicals in China.

  • Application of Various Chemicals in Mining

    The beneficiation processes for tin and tungsten ores typically involve stages such as crushing, grinding, concentration, and dewatering. The concentration stage may employ gravity separation and flotation, while the dewatering or tailings treatment stage commonly uses polyacrylamide (PAM) as a flocculant to facilitate the settlement of fine particles. The primary function of PAM is to enhance sol...

  • Unlocking Oil Recovery Potential: How Oilfield Polyacrylamide Tackles Reservoir Challenges

    1. Balancing Polymer Size and Pore Throat Dynamics‌Imagine oil reservoirs as intricate mazes with varying tunnel sizes. For low-permeability formations, the narrow pore throats pose a dilemma: inject polyacrylamide polymers too large, and they’ll clog the pathways; too small, and they’ll bypass the oil. Advanced molecular engineering steps in here. By tailoring the polymer’s molecular weight and h...

  • How To Use Anionic polyacrylamide (APAM)

    Anionic polyacrylamide (APAM) is an important chemical additive commonly used in water treatment, mineral processing and pulp processing. As an efficient flocculant, APAM has a strong negative charge and can quickly adsorb positively charged impurity particles in water to form large floccules, thereby improving the efficiency of solid-liquid separation. This article will introduce in detail the us...
