Get into the thick of things

摘要

In most parts of the chemical industry,viscosities are on the rise.This is a universal response to demands such as those to cut levels of volatile organic compounds and to improve onsite performance of high-solids water-borne products.As this trend accelerates,many manufacturers are finding that the mixing equipment they have relied on for years is now inadequate.To adapt,many are moving from simple dual-shaft mixers to more robust triple-shaft units.Others are upgrading to double planetary mixers and hybrid planetary designs or opting for an agitator that can obviate a double-arm kneader.
