Heat calculation for powder coating oven

Heat calculation for powder coating oven The basic of the powder coating oven design is to find out the necessary heat. Need to calculate the heating up time (from the start of the switch to the time to reach the temple temperature) sweep heat, the necessary heat per hour during production operation, according to the calculation results to decide the capacity of the heater (such as the burner) and the capacity of the circulation fan. (1) Heat when heating

The identification method of powder coating

The identification method of powder coating I. Appearance identification method 1. Hand feeling: hand feeling is silky smooth, peng loose, floating. Feel rough, sinking hands, feel heavy. Grab a handful of powder in the hands, the smoother the powder pescado, good quality, and vice versa powder rough feel heavy, poor quality, not easy to spray, the second fall powder, waste. 2. Volume: the larger the volume, the less filler within the powder coating, the higher the co

Powder coating storage, construction environment, light loss phenomenon and treatment Storage of powder The storage of powder has a great influence on its quality. The storage of powder will generally be in a ventilated and dry place, and the temperature of the storage space should not exceed 30 degrees. Different varieties of powder can not be placed together to avoid mutual pollution. Different manufact

Powder coating and its precautions

Powder coating and its precautions Powder coating refers to a new type of solvent-free 100% solid powder coating. It is solvent-free, non-polluting, recyclable, environmentally friendly, saves energy and resources, reduces labor intensity and has high mechanical strength of the coating film. Classification Powder coating is a completely different form from the general coating, it exists in the state of mic

Reasons and treatment of powder coating powder drop phenomenon after coating

Reasons and treatment of powder coating powder drop phenomenon after coating The lower the dielectric constant of powder, the easier it is to charge the particles, but the easier it is to lose the charge, which is reflected in the powder adsorption force on the workpiece, and the powder will fall off when it is slightly vibrated. For electrostatic spraying powder coating, should be as high as possible with the high dielectric constant, it will make the powder adsorption force greatly im

Several ways to identify the authenticity of powder coatings

Several ways to identify the authenticity of powder coatings There are several ways to identify the authenticity of powder coatings. I. Appearance identification method 1. Hand feeling Hand feeling is silky smooth, loose, floating. Feel rough, sinking hands, feel heavy. Grab a handful of powder in the hand, the more smooth powder pent loose, good quality, and vice versa, the powder rou

Metal pretreatment cleanliness testing method

Metal pretreatment cleanliness testing method In simple terms, the role played by metal degreasing is to remove the dirt accumulated on the metal surface during previous operations and to prepare it for subsequent operations. Cleaning metals involves not only the selection of the type of degreasing agent, but also the appropriate degreasing process and process equipment that must be used to obtain a qualified part at a given rate (parts

What standards are needed for electrostatic powder coating

What standards are needed for electrostatic powder coating 1. The fineness of electrostatic powder particles: The significant difference between powder coatings and solvent-based coatings is that the dispersion medium is different. In solvent-based coatings, the use of organic solvents as a dispersion medium; and in powder coatings, the use of purified compressed air as a dispersion medium. Powder coatings are dispersed during spraying and the granularity of the coating cannot be

Process control of electrostatic automatic spraying machine

The coating line uses high-pressure electrostatic automatic spraying system, in the actual process of production, we have to constantly figure out the construction characteristics of various colors; for different coatings, you need to choose the right automatic sprayer parameters (paint volume, forming air pressure, voltage value), the impact of the adjustment range on the appearance are to be figured out in the actual production, which is very important for on-site construction adjustment
