EVAL™ EVOH RESINS, A PROTECTIVE LAYER AGAINST CHEMICALS

摘要

The need for materials of construction to meet the ever-changing requirements of solutions which will attack METAL is growing in many industries. Currently, metals of stainless steel, Carpenter 20 , Hastelloy or other special alloys may be suitable due to pressure, size and temperature. But the last 40 years has seen an explosion of designs of pumps, filters, pipe-valve-fittings, and even eductors for mixing, meet the challenge and in some cases could be the better choice. Virtually all industries should explore the possibilities. The cost may not be less but the resistance to corrosive attack and the resulting failure, and downtime or safety may make a polymer product the first choice. What are some of the area is where plastic will be preferred - possibly nuclear, power production, petrochemic, chemical, desalinization, paper and steel mills, cooling tower and cleaning, waste treatment, food and beverage, photo development, metal finishing (plating-painting-electrophoretic) etc.
