in the manufacture air filter a variety of raw materials that are used in this topic can be to the polyurethane in the production of air filters adopted. continue with us to the ... polyurethane to know more.
polyurethane in the production of air filters
some of the raw materials, the production of air filter such as these have been of the. ISO paper folded standard filter-air, paper, raw filter, air, Jan the PDF etc. glue کاغذفيلترهوا., the internal فيلترهوا.
the advantage of using polyurethane in the production of air filters
polyurethane, the material, style, weight are the application of the polyurethane to the environment help a lot because the weight is less material in used car compared to other polymeric materials. This advantage also reduces vehicle fuel consumption and reduce انتشاز polluting emissions in the environment.
during the years, up to ۴۰ percent reduction in material consumption there, while the efficiency and quality of the final product, the final has been preserved. For example, the foam seat is one of the fragments has the lowest density in the other parts used in the car.
air filter car
polyurethane in the production of air filter : in the production of air filters for use as filter, car rides, etc., filter, heavy vehicles and even filter industrial, often of polyurethane foam flex soft foam can be used.
compounds, polyurethane foam
polyurethane foam used in the filter storage from combining two liquid chemical called ایزوسیانات briefly that the ISO was first used in the resin Poly El briefly that Poly is called with the attributed specified is produced.
the ratio of the composition Poly El to ایزوسیانات usually three to a can be for the use of the material Poly-net that the proportion by machine production of polyurethane foam can be adjusted.
also, add a filler, thereby more concentrated of the resin Poly El is caused to enter the coming pressure to the pump, injection device, and the depreciation of the foam injection machine will. The quality of foam air filters manufactured in addition to the purity of the raw materials, polyurethane function of other factors, including the amount of the weight of foam per unit volume of the filter is, how to mix the material with machine or manually, etc as well.
