Production Processes and Classification of Polyacrylamide (PAM)
Advantages of PAM: Low cost, simple equipment, high safety, and the ability to achieve very high molecular weights; suitable for large-scale production of 25kg-bagged dry powder.
Why does snow melt more easily after spreading calcium chloride ?
Calcium chloride can melt snow. After dissolving it into the snow, the freezing point of water is significantly lowered. After using calcium chloride , the freezing point is depressed, allowing snow to melt even at temperatures between -5°C and -20°C. While pure water freezes at 0°C, a calcium chloride solution has a much lower freezing point—often reaching as low as -20°C—which means snow can tu
We frequently consume beverages, but have you ever taken a look at the bottle bottom? You might notice a number in one triangular recycling. Do you know what means of these?
First, the "triangle" is a plastic recycling symbol.
Second, the numbers 1-7 inside the triangle indicate the specific type of plastic material used to manufacture these bottles.
Aluminum Chlorohydrate (ACH) is a high-basicity inorganic polymeric aluminum coagulant. It is available as colorless & transparent liquid or white hygroscopic powder. Basicity: 75~85%. Liquid grade: Al₂O₃ ≥23%; Solid grade: Al₂O₃ ≥46%. ACH features high content of polynuclear aluminum ions, low residual aluminum in treated water, low sludge yield, good coagulation performance even under low water
Both EDTA-2Na and EDTA-4Na are sodium salt derivatives of EDTA and possess metal ion chelating ability, but they are significantly different in their functional properties, applicable pH range, solubility, and main application areas.
Nonylphenol Ethoxylate (NPE / NP series) is non ionic surfactant, produced by ethoxylation of nonylphenol. The number after NP stands for EO (ethylene oxide) mole count. Higher EO value brings better water solubility.
Sodium hydrosulfite is widely used in the textile industry for its reducing dyeing, reducing cleaning, printing, and bleaching, as well as for bleaching silk, wool, and nylon fabrics. Because it contains no heavy metals, fabrics treated with it retain vibrant colors and are less prone to fading. Furthermore, sodium hydrosulfite is used for bleaching food products such as gelatin, sucrose, and hone
Natural lutein is yellow-orange powder with extremely strong coloring power. It is mainly used in poultry and aquaculture industries for coloring poultry skin, egg yolks, and shanks. Because animals cannot synthesize lutein themselves, they can only absorb lutein from feed and the colors deposited in their bodies
Reasons for Price Volatility in Polymer Polyol (POP)
POP（Polymer Polyol） is a polyurethane intermediate; its cost is heavily tied to crude oil-based chemical feedstocks, and it is characterized by highly cyclical downstream demand, low supply elasticity, and frequent disruptions from trade and policy factors. The convergence of these elements leads to significant price swings and rapid market shifts.
