In electrostatic powder coating, the curing furnace is the key equipment. The quality of the paint film has a very important relationship with the temperature of the curing furnace. The heating method of the powder curing furnace can be divided into two categories: one is the hot air circulation type, The second type is the infrared radiation heating method. Hot air circulation heating can be divided into direct heating and indirect heating. There are two heat sources used for direct heating, electric heating spiral fin type and gas type direct heating. The advantages of the direct electric heating spiral fin type are uniform temperature in the furnace and strong adaptability of the workpiece: the solid state relay PID is used to adjust the temperature. The temperature deviation in the powder coating oven is small. The disadvantage is that the heating time is slow and the equipment power is large, and it is not fit for used as an industrial powder coating oven. Because it is heated by hot air circulation, the curing process is easy to cause secondary pollution of dust. The furnace occupies a large area. The advantages of the gas-fired direct heating method are fast heating speed, high heat energy conversion rate, proportional adjustment control for furnace temperature control, and small temperature control deviation in the warm furnace. Because the burner flame burns directly in the combustion chamber, the curing process is likely to cause secondary pollution of dust and exhaust gas, which is not suitable for use as a home powder coating oven. A high temperature resistant filter should be installed in the heating chamber, so that the full pressure of the circulating fan should be considered in the selection of the fan. In addition, the heating indoor plate must be made of stainless steel plate, the cost of these two equipment is relatively Increase, the furnace covers a large area.
Powder coating filter is a kind of multi-purpose filter equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work and strong adaptability. It is a pressure filter device. The liquid flows into the filter bag from the inlet pipe on the side of the filter shell. The filter bag itself is installed in the reinforcement net. The liquid penetrates the filter bag of the required fineness grade to obtain qualified filtrate. Impurity particles are captured by filter bags. The machine is very convenient to replace the filter bag, and there is basically no material consumption for filtration. This filter can be applied to 1. Nanofiltration (NF), ultrafiltration (UF), reverse osmosis (RO), electronic membrane deionization (giant D,) and other system security filtration; 2. Filtration of pharmaceutical injections, large infusions, eye drops, Chinese herbal medicines, etc., extraction, purification and concentration of biological preparations; 3. Pre-filtration of high-purity water for electronics, microelectronics, and semiconductor industries; 4. Filtration of oilfield re-injection water, boiler feed water, chemical reagents, liquid organic products, high-purity chemicals, concentrated drugs, etc.; 5. Drinking purified water, mineral water, fruit juice, tea drinks, health drink filtration, etc.
