For hook mesh immersion is one of the methods of anti-corrosion, now the domestic more mature method is: powder immersion method, it originated from the fluidized bed method, the so-called fluidized bed is used in the Winkler gas furnace on the oil contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in metal coating. So sometimes it is still called “fluidized bed coating method”, the actual process is to add the powder coating to the bottom of the porous, breathable container, the blower from the bottom into the treated compressed air, so that the powder coating turned to the “fluidization state”. It becomes a fine, evenly distributed powder.

With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.

Economic Significance
In summary, HEC and HPMC are versatile cellulose derivatives that play vital roles in various industries. While both are effective as thickening agents and stabilizers, their differing solubility, viscosity, and applications make them suitable for specific uses. Understanding the distinctions between HEC and HPMC can aid formulators in selecting the appropriate polymer for their products, ultimately leading to improved quality and performance. As industries continue to evolve, these cellulose derivatives will likely remain integral to the development of innovative formulations.
- The viscosity of HEC solutions also varies with temperature, with higher temperatures typically leading to lower viscosities. This is because higher temperatures disrupt the interactions between polymer chains, reducing the overall viscosity of the solution. However, the exact relationship between temperature and viscosity can vary depending on the specific characteristics of the HEC polymer.
HPMC viscosity tables are used to provide a reference for the viscosity of HPMC solutions at different concentrations and temperatures. These tables are essential for formulators and researchers to predict the behavior of HPMC in different formulations and conditions.
