Abstract
The utility model discloses double face compound glass fibre filter paper, belonging to the fields of the filter of glass fibre and paper technology. The utility model is characterized in that the both faces of the glass fiber paper which use a filtering layer are covered with the supporting protective layers of natural mulberry fibre paper, and the supporting protective layers of natural mulberry fibre paper are glued by agglomerant. The compound glass fibre filter paper can filter gas, and can also filter liquid. The double face compound glass fibre filter paper is mainly used for the rough filtration and the fine filtration of the liquid. The utility model has the advantages of high strength, and high efficiency. When filtering, the double face compound glass fibre filter paper can prevent or avoid the phenomena of the hair slipping and pollution. When the double face compound glass fibre filter paper is used for filtering the gas, the filtering efficiency is 99.99%-99.9999%; when the double face compound glass fibre filter paper is used for filtering the liquid, the rough filtration is 10 mu-25 mu, and the fine filtration can obtain 0.5 mu-3 mu.
Description
Two-sided composite glass fiber filter paper belongs to glass fibre filtration, pulp technology for making paper.
The dielectric material that generally is used for filtering gas is used full mineral wool or full all-glass paper usually, but during with above-mentioned filtration of material, because intensity is low, breaks easily, and glass fibre tends to split away off, and is commonly called as " fall mao " phenomenon, and this causes self-pollution on the contrary easily.And be used for the dielectric material of filter liquide, and usually with imitation parchment or wire netting, but the filter efficiency of imitation parchment is low, only can be as the usefulness of coarse filtration, and superfine close wire netting is then used in the filter of the essence of image height level aviation gasoline, but also often stop up easily.
Task of the present utility model provide a kind of can filtering gas again can filter liquide, be mainly used in the two-sided composite glass fiber filter paper of the usefulness of coarse filtration, clear filter for liquid.
Structure of the present utility model as shown in the figure.
The all topped support protective layer (1) that natural mulberry fibre is arranged on the two sides of glass fibre filter course (2), with the binding agent that accounts for extrusion coating paper gross weight 1%～3%, spray makes it combine on extrusion coating paper after the drying between three layers.Binding agent is polyvinyl alcohol or acrylate.The thickness of glass fibre filter course is 0.5～0.05mm; the thickness of the support protective layer of natural mulberry fibre is 0.1～0.01mm; support protective layer except that with the natural mulberry fibre paper, also available synthetic fibre paper is as replacement mulberry fibre paper such as polyester fiber paper, polypropylene fibre paper.
The advantage of two-sided composite glass fiber filter paper is to manufacture conveniently; higher-strength is arranged; area is the paper tape of 15mm * 200mm; intensity is not less than 2kg; because the protective layer of mulberry fibre paper is all arranged on the two sides of glass fibre filter course; therefore, when being used to filter, avoid and prevented the appearance of " falling hair " phenomenon.The filter efficiency height, be used for gas filtration: efficient can reach 99.99～99.9999%, be used for liquid filtering: coarse filtration is 10～25 μ, smart filter can reach 0.5～3 μ, can satisfy the filtration requirement of senior aviation gasoline, also can be used for making the filter element of the hydraulic drive servo-drive system of boats and ships and heavy-duty machinery.
Claims (5)
1, two-sided composite glass fiber filter paper is characterized in that all topped support sheath that natural fiber paper is arranged in two sides as the all-glass paper of filter course, and bonds them together by binding agent.
