The high temperature resistant filter is designed with a clapboard. The corrugated clapboard can keep the distance between the pleats. Under small resistance, the filter material can be used as much as possible. The filter material has 180 pleated pleats on both sides. When the filter material is bent, there are two indentations to make it form a wedge-shaped box pleat at the end of the clapboard. The wedge-shaped box pleat can prevent the filter material from being damaged. Sffiltech is a popularhigh-temperature filter manufacturer.
The material of high temperature resistant filter is different from that of general filter, which is mainly reflected in the characteristics of high temperature resistance.
The main materials of high-temperature filter are as follows:
The closed hole EVA sealing gasket can be sealed with dry gas tightness to prevent side leakage of the filter. The standard is 18mm wide and 6mm thick. Silicone sealing gasket can also be used, and polyurethane foam can be used to form a whole without partition. The foam machine runs on XY axis automatically, and the sealing effect is quite good.
Wedge fold
Both sides of the filter material are folded 180 degrees to form wedge-shaped folds. There are two indentations when the filter material is bent to form wedge-shaped box folds at the tail end of the diaphragm. The wedge-shaped box folds can prevent the filter material from being damaged. Some filter manufacturers use single indentation or rolling indentation filter material pleats, or even simply manual origami. Under such idle conditions, the filter material is easily damaged by the sharp folding top of corrugated partition. Or the filter paper may be damaged during excessive handling.
filter material
The filter material is high-density paper made ofultra-fine glass fiber.The material is pleated to maximize the filtering area of the material distribution, thus reducing the filtering speed of the filter material, which is very important for the filter Wave fiber filter material is waterproof and flame retardant, and can be applied to high temperature of 1000 ° F (538 ℃),
The closed hole EVA sealing gasket can be sealed with dry gas tightness to prevent side leakage of the filter. The standard is 18mm wide and 6mm thick. Silicone sealing gasket can also be used, and polyurethane foam can be used to form a whole without partition. The foam machine runs on XY axis automatically, and the sealing effect is quite good.
