Abstract
The utility model relates to a filter paper and aims to provide a fuel filter paper which is applied to a fuel filter and has high filtering precision and good fat resistance. The high-precision fuel filter paper comprises a filter layer made of paper. The surface of the filter layer is provided with a fine-wrinkle passage and is uniformly coated with a layer of high-strength oil resistant latex layer. Compared with prior fuel filter paper, the high-precision fuel filter paper of the utility model has higher filtering precision, strength, stiffness and fat resistance.
Description
Technical field
The utility model relates to a kind of filter paper, particularly a kind of high accuracy fuel oil filter paper of using in fuel filter.
Background technology
Fuel oil filter paper is the crucial building block in the fuel filter, is determining the performance of fuel oil filter.It is the filter course a kind of made of paper that Main Ingredients and Appearance is made that fuel oil filter paper generally includes with common wood pulp, because the normal wood pulp fibres is thin, tightness is high, shortcomings such as therefore made fuel oil filter paper ubiquity the tightness height, filter efficiency is low, the life-span is short, oil resistivity is poor, and deflection is not good.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of filtering accuracy height and grease resistance good high accuracy fuel oil filter paper.
In order to address the above problem, the utility model is to be achieved by following technical solution:
A kind of high accuracy fuel oil filter paper comprises filter course made of paper, and the surface of described filter course is provided with tiny wrinkle passage.
As a kind of improvement, the surface of described filter course also evenly is coated with one deck emulsion layer.
Compared with prior art, the beneficial effects of the utility model are:
Because the surface at filter course made of paper is provided with the tiny wrinkle that is covered with, and makes fuel oil that filtration channel arranged, and increased the area that filters; The surface of filter course also evenly is coated with the emulsion layer of one deck high strength and oil resistant, has increased intensity, deflection and the oil resistivity of fuel oil filter paper, thereby has improved its filtering accuracy and life-span.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In conjunction with the accompanying drawings, below the utility model is described in further detail.
High accuracy fuel oil filter paper of the present utility model comprises filter course made of paper 1, and the surface of filter course 1 is provided with tiny wrinkle passage 3, and wrinkle passage 3 is the irregularly shaped whole filter paper surface that is covered with.The formation of wrinkle is to be undertaken wrinklingly in pressing the corrugation operation by pressure roller, can increase the deflection and the filter area of filter paper.Also evenly be coated with the emulsion layer 2 of one deck high strength and oil resistant on the surface of filter course 1, further increase intensity, deflection and the oil resistivity of fuel oil filter paper, thereby improve the filtering accuracy and the life-span of fuel oil filter paper.
The measurement result of high accuracy fuel oil filter paper of the present utility model sees Table one:
(quantitative mensuration adopts GB/T451.2-2002 paper and the quantitative determination method of cardboard, and the mensuration of bursting strength adopts the mensuration of GB/T454-2002 paper bursting strength.)
Table one: the technical indicator of high accuracy fuel oil filter paper
