This article uses the life analogy of "undissolved sugar precipitating at the bottom of oversaturated sugar water" to explain the principle of precipitation in PVC production in a plain and easy-to-understand way. Combined with 4 common real workshop cases, it clearly illustrates the appearance characteristics and inducing factors of different types of precipitation. It also provides 5 practical on-site troubleshooting tips that do not require laboratory testing, helping production personnel quickly locate the root cause of precipitation without blind trial and error, so as to reduce waste loss and restore stable operation of the production line.

For practitioners in plastic processing, coatings and ink industries, it is common to get stuck between low-cost low-viscosity and high-temperature high-viscosity polyethylene waxes. This content avoids obscure professional formulas, and explains the practical logic through a daily analogy of boiling syrup: the high-temperature production process removes volatile low-molecular impurities, preventing wax decomposition, precipitation and coking under processing temperatures of 100℃-200℃, which helps stabilize production speed and reduce defective products. The high-viscosity feature with large molecular structure can enhance pigment dispersion, product scratch resistance and temperature tolerance, covering scenarios from color masterbatch, PVC profiles to coatings, inks and hot melt adhesives. Despite a slightly higher unit price, it effectively cuts hidden costs caused by rework and material replacement.
