Air FilterManufacturer: ProductionAir FilterWhat are the steps in the process?

I believe we all understand the principle of air filter, but the air filter production process? Because it should be relatively unfamiliar, because this is the core technology of air filter manufacturers.

The production process of air filters is divided into five production steps, details of which are as follows:

(1) Air filter outer frame is installed, the outer frame has, aluminum frame, galvanized frame, prepare the filter outer frame, cardboard, latex, homemade bonding agent, kraft paper and so on. Brush a layer of homemade adhesive on the inner wall of the outer frame of the air filter and let it dry. Glue the appropriate width and narrow size of the paper strip, the protruding part of the first from the bottom of the cartridge inserted between the priority folded paper layer and the corrugated board, and then the latex evenly coated on both sides of the cartridge face of the filter paper. Then stick the two sides of the protruding part on the other two faces of the filter cartridge and air dry or dry.

(2) air filter cartridge (filter paper) purchase this is an important part, because the cartridge is directly related to the quality of the entire air filter, that how to buy air filter cartridge, the use of light detection method, will be qualified for the filter core through the light inspection device, carefully check, such as found in pinholes, glass slag, grass stalks, foreign matter, should be coated with latex in the place, the use of a small area of the same material of the filter paper Paste repair. There are broken filter paper need to be cut off, connected to the qualified paper, seams when the paper is cut flush, one side coated with latex, the other side of the spreading paste on the side coated with latex, gently pressed by hand, and then in the seams and then coated with a layer of latex, baked with an electric hair dryer, glue drying and then folded.

(3) air filter cartridge folding; will be qualified by the light test cartridge paper on the folding template for folding, folding process, you must make the folding template and the filter paper on one side of the alignment, along the prongs of the template folded up, folded up the filter paper against the fixed planks of the workbench. Then put the folded filter paper flat on the workbench, withdraw the folding template, measure the size, and cut off the part of the filter paper that is too wide.

(4) glue; in the glue before the third and fourth two folds of the width of the appropriate cut off, and then, in the middle of the two folds of the cut short glue to make it stick tightly, and then the priority and the second folds of the glue, so that it is upside down to the side of the two folds of the layer of the pressure on the short cut above the layer of the paper, flattened with a spatula, and then the fifth folds of the layer of the glue, pressed on the layer of the fourth folds of the paper, and then after the sixth, the seventh, and so on until all the irrigation is completed. The other end of the cabinet with the same irrigation method. In addition to the two ends of the face of the glue, up and down the two edges should also be filled with glue. Required to fill the glue place are filled twice.

(5) One end of the folded air filter cartridge will be 15 millimeters from the edge of the place to draw a pink line, this line shall prevail, measure the required size, draw a line at the other end. Then put the support partition inside the paper core, up and down each fold of filter paperboard should be put between a support partition, and make the sticky head paper side at the bottom of the paper fold, the position of the support partition should not exceed the line drawn. Put the cartridge with the support partition on the jig, adjust it to the required size and fix it.

Put the processed filter element into the outer frame of the air filter which has already been pasted with paper strips in the designated parts with latex, so that the two sides of the sticky kraft paper are aligned with the two sides of the pasted paper strips. The kraft paper and paper strips are glued with latex, and a layer of adhesive is brushed after the glue dries. The gap between the two end surfaces of the cartridge and the shell, filled with crushed filter paper, stuffed with glue or crushed paper dipped in glue. Plug to slightly below the height of the paper layer when filling a layer of latex. Be careful when stuffing, to prevent the cartridge wrinkles or stuffing broken. Stuffed tightly, in the shell and cartridge contact with the surrounding surface brush a layer of adhesive, and then dry and then fill the latex. Priority after drying, still need to brush layer of adhesive, and then irrigation for the second time, a total of three times. After filling the rubber are required to dry or drying, in the filter processing and filter assembly, there are continuous filling of rubber operation steps, because the latex has a period of use, more than l5 days, so in case of rainy days or low temperature, the latex is not easy to dry, need to be placed in the oven to bake. Baking temperature shall not be higher than 60 degrees.
