can you count the letter "e" in:
scope of application: large metal parts, large aluminum (magnesium aluminum) alloys, etc.
heating energy: gas, electricity, etc.
heating system: burner, heating tube, etc.
conveying form: lifting, step walking, beat walking, etc.
water pump body: general, stainless steel, corrosion-resistant pump, etc.
exhaust air ducts: corrosion-resistant raw materials, galvanized pipes, pp pipes, stainless steel pipes, etc.
hardware pre-treatment production line coating line is a product that competes in the current assembly line market. the seven components of the coating line: pre-treatment, powder spraying system, paint spray equipment, oven, heat source system, electrical control system, hanging chain etc. it is suitable for spray painting and plastic treatment of the contours of workpieces, and is mostly used for the coating and camouflage industry of single or small batches of workpieces, and transportation and homework of joint ventures, electric trolleys, and aerial machines.
the small whirlwind + filter element acceptance in powder spraying is a more advanced elder, and the color change is faster. the powder spraying system is imported, and components such as the powder spraying room and the electric machine landing gear are all domestically produced.
such as oil spray paint booth, water curtain paint booth, can be painted on the outside of bicycles, car leaf springs, large loaders.
the oven is one of the tensions in the coating consumer line, and its temperature uniformity is the tension in the quality of the tube coating. the heating system of the oven includes: radiation, hot air cycle and radiation + hot air cycle, etc. the certificate can be divided into single room and passing type, and is equipped with straight-through and bridge type. hot-air recirculating ovens have good thermal insulation, uniform temperature in the furnace, and low heat loss. after testing, the temperature difference in the furnace is less than ± 3oc, which can reach the performance of similar products.
