How can we simply and intuitively determine the quality of hydroxypropyl methylcellulose (HPMC)?

When hydroxypropyl methylcellulose (HPMC) is added to water and forms a transparent colloid, observe its light transmittance. The higher the light transmittance, the better—indicating fewer insoluble particles in the solution. Vertical reactors generally exhibit superior light transmittance, while horizontal reactors tend to perform slightly worse. However, this does not necessarily mean that products from vertical reactors are of higher quality than those from horizontal reactors; many other factors also influence product quality.

Uses of Hydroxypropyl Methylcellulose (HPMC)

In putty, cellulose ether primarily serves to retain moisture, enhance adhesion, and provide lubrication, thereby preventing cracks and dehydration caused by rapid water loss. At the same time, it improves the putty’s adhesion, reduces sagging during application, and ensures a smoother, more successful construction process.

What are the applications of polyacrylamide (PAM) in water treatment?

The biopharmaceutical industry is a major polluter. The wastewater it discharges not only has high concentrations of organic pollutants but also contains various factors that inhibit microbial growth. By employing conventional wastewater treatment technologies, excellent treatment results can be achieved. The biopharmaceutical industry uses grains as raw materials and ferments specific medicinal microorganisms through cultivation.

Cationic polyacrylamide is used as a sludge dewatering agent.

The wastewater treatment process generates large amounts of sludge. First, it is essential to clearly identify the origin of the sludge, its physical properties, its composition, and its solid content. Wastewater from different industries has varying pH levels, resulting in sludges with distinct compositions, particle sizes, charge characteristics, and charge densities.

Pile-driving sand-washing slurry sedimentation agent polyacrylamide

Pile-driving and sand-washing slurry sedimentation agents—drilling and pile-driving slurry wastewater is known for its high concentration. Generally, there are two main approaches for using sedimentation agents during the drilling process: one is to enhance lubricity, and the other is to treat the slurry wastewater by means of sedimentation agents. To gain a comprehensive understanding of the use of polyacrylamide flocculants in the drilling process, let’s first familiarize ourselves with the basics of drilling.
