Abstract
The invention relates to an oil filter paper, which comprises resin, the weight percentage of which is larger than 0 and less than and equal to 25 percent; inorganic fiber, the weight percentage of which is larger than 0 and less than and equal to 20 percent; and wood pulp fiber, the weight percentage of which is larger than and equal to 55 and less than 100 percent, wherein, the inorganic fiber adopts glass fiber or the mixture of the glass fiber and ceramic fiber; through adding certain inorganic fiber composed of the glass fiber and the ceramic fiber to the wood pulp fiber, the inorganic fiber can adjust the filtering precision and air permeability of the oil filter paper, and reduce the pore diameter of the oil filter paper, meanwhile improve the hydroscopic property and strength of the oil filter paper, so as to facilitate the oil filter paper to adsorb and remove the foreign impurities in the oil effectively, improve the quality and the utilization rate of the oil.
Description
Technical field
The present invention relates to a kind of filter paper for oil.
Background technology
Along with the process of building well-off society, the industrial and agricultural production develop rapidly in the whole nation, industry production such as oil, automobile, engineering machinery, power industry, metallurgy industry are increasing with oil (as all kinds of senior lubricants, generating set turbine oil, I. C. engine oil, supply transformer oil and heavy-duty machinery hydraulic system oil) amount, and each class lubricating oil advances after the use after a while, solid impurity wherein, moisture, gas and greasy filth all can increase, and the quality of oil is constantly worsened.Solid impurity can destroy oil film, the damage of acceleration equipment, when the particle diameter of solid impurity greater than or during near the friction gap, big especially to the damage of equipment.Moisture in the oil can make plant equipment produce and lure erosion, brings serious harmful effect can for the thickness and the intensity of oil film.Gas in the oil brings the oxidation of oil product and destroys oil film and cause wearing and tearing.The oxidation and the acidifying meeting that bring under the higher environment of moisture and gas componant when the lubricating oil long-time running make the aging greasy filth that produces of oil product.With interpolation antioxidant, when preventing lure, greasy filth is separated out especially easily at additional fresh oil, and the generation of greasy filth not only can influence oil quality, also can cause problems such as oil circuit is smooth, filter screen obstruction.
Be becoming tight in current oily resource day, in order to improve oil quality, allow limited oily resource give play to bigger efficient, this must select the oil quality that a kind of splendid oil purification method obtains high pure degree, a kind of filter purification method commonly used is arranged in the oil purification method, and it utilizes filter elements such as fiber filter paper to come clean oil, under certain pressure, oil is by behind the various filter elements, and solid impurity in the oil and part free water just can be by filterings.The advantage of this method is that operating principle is simple, and operating cost is low, but its filtering accuracy is not high, filter paper immersion back intensity variation.
Summary of the invention
The purpose of this invention is to provide all very high filter paper for oil of a kind of filtering accuracy, filter efficiency.
Technical scheme of the present invention is: a kind of filter paper for oil, comprise percentage by weight greater than 0 smaller or equal to 25% resin, percentage by weight greater than 0 smaller or equal to 20% inorfil, percentage by weight more than or equal to 55% less than 100% wood pulp cellulose, described inorfil is the mixture of glass fibre or glass fibre and ceramic fibre.
Described wood pulp cellulose is a needle pine pulp fibres.
This filter paper for oil also comprise percentage by weight greater than 0 smaller or equal to 20% cotton fiber.
Described resin is one or more the mixture in phenolic resins, melmac, the acrylic acid modified resin.
The fibre diameter of described glass fibre is 10～14 μ m.
The fibre diameter of described ceramic fibre is 2～6 μ m.
Beneficial effect of the present invention is: by increase certain inorfil of being made up of glass fibre and ceramic fibre in wood pulp cellulose, this kind inorfil can regulate filter paper for oil filtering accuracy and permeability, reduce the aperture of filter paper, the water imbibition and the intensity of filter paper for oil have meanwhile also been increased, make filter paper for oil can effectively adsorb the impurity of getting rid of in the oil, improve oil quality and utilization rate.A plurality of embodiment products of the present invention are tested its performance as follows:
The mensuration of paper tensile strength is according to standard GB/T453-1989; The mensuration of wet tensile (strength) is according to standard GB/T465.2-1989; The mensuration of bursting strength is according to standard GB/T454-1989; The mensuration of air permeability is on the Xiao Baishi densometer, installs a Y-61 type inclined minute-pressure instrument additional, reduces its vacuum, uses 1 millimeter of water pressure reduction to measure.
The maximum diameter of hole adopts bubble method to measure, each aperture of paper is regarded as a capillary, with the wetting l Water Paper page or leaf of isopropyl alcohol, and page imposed hydraulic pressure, when the outside air pressure of opposite direction reaches a certain value, bubble is located to emerge earlier in the page maximum diameter of hole, and the diameter in this hole has certain relation with the pressure differential of this moment.According to certain conversion relation, can calculate the maximum diameter of hole of page.Calculate the page maximum diameter of hole according to following formula:
