High-precision fuel filter paper production process

The general fuel filter adopts a star filter paper folding structure. Inside the fuel filter, the folded filter paper is connected with both ends of the plastic or metal filter, and after the sewage enters, the outer wall of the filter passes through the layer. The filter paper is filtered and reaches the center, and clean fuel flows out. This type of filter paper generally uses corrugated fuel filter paper.

The higher-end engine uses high-precision filter paper, spiral fuel filter, unlike the star fuel filter, its filter paper is wrapped in the center tube, the space utilization is high, and it can accommodate larger in the same space size. The filter area is generally 3 times that of a star filter. After the slop oil enters, it is directly filtered through the filter paper and then flows out, and the foreign particles are retained in the groove of the filter paper. This fuel filter has superior performance and can make fuel filtration more accurate.

The main research contents of high-precision filter paper: 1 pulp material selection; 2 process parameters determination; 3 creping scraper selection; 4 wet strength agent selection; 5 anti-water rubber material application.

The technical specifications of high-precision fuel filter paper are shown in Table 1:
