Replacement of Loctite enamel coating on internal parts of diffusion apparatus DS-8 in food industry with Spramet-100-P anticorrosive metal coating

Spramet-100-P anticorrosive coating meets the requirements of the FEZ. Warranty service life, provided that the requirements are met - up to 10 years. Equipment: diffusion apparatus DS-8 sugar factory. Problems to solve: replacement of enamel coating; use of ferrous metal instead of stainless steel; reduction of thermal conductivity coefficient; reduction of product losses at the outlet; longer service life; ensuring sanitary requirements; reduction of total costs. The required operating conditions of the part: the thermal conductivity of the material is required maximum, the medium temperature is up to 130 degrees Celsius, abrasive effect, service life from 2 to 8 years, chemical medium ph-3.5. Characteristics of the part without coating: base - black metal, before replacing the coating - enamel. Customer problem: low life and quality of enamel coating. The enamel coating collapsed 6 months after application. Parts that have been in operation. Solution of Plakart JSC: anti-corrosion coating based on aluminum Spramet-100P. The part is subjected to sandblasting and degreasing. The coating is applied by electric arc metallization. Such solution provides operating life of diffusion apparatus surface DS-8 at least 4-5 times higher than enamel coating. Economic effect: over 60 % on repair and simple equipment. Spramet coating - 100P: meets the requirements of the FEZ; resistant to mechanical action and oxidation; operating temperature up to 600 degrees Celsius; high corrosion resistance; warranty service life provided that the requirements are met: up to 10 years.
