Description
Technical field
The present invention relates to a kind of fuel oil filter paper and production technology thereof.
Background technology
The oil supply system of domestic existing little car engine normally adopts oil pump to supply with at present, because the oil mist particles that oil pump feed produces in cylinder is big, therefore contains a large amount of unburnt fuel in the vehicle exhaust of discharging, and the air pollution situation is serious.Be energy savings, reduce pollute that Chinese ic engine industry association, China Association for Automobile Manufacturers, State Environmental Protection Administration plan the end of the year 2007 domestic each metropolitan cars and reach Europe III discharge standard.Reach the method that Europe III discharge standard must change original oil pump for engine oil spout, as adopt the electric injection device fuel feeding can make the utilization rate that improves fuel oil, and adopt the electric injection device fuel feeding to need a kind of novel fuel oil that the filtering material supply is more cleaned, purity is higher, it is little just to reach spraying granule, fuel oil is made full use of, reduce discharge amount of exhaust gas.The filter effect of common high-grade fuel oil fitering element device is better, adopt multilaminate coiled formula filtration method to filter in this filtering core device, multilaminate coiled formula filtration method has increased fuel oil circulation and filtering accuracy than the collapsible filtration method fuel oil filter paper of traditional individual layer, but multilaminate coiled formula filtration method adopts common fuel oil filter paper, and its filter efficiency is still limited.In the today of being becoming tight oily resource day, in order to improve oil quality, allow limited oily resource give play to bigger efficient, press for that to invent out a kind of filter efficiency higher, obtain the filtering material of extreme high purity oil product.
Summary of the invention
The purpose of this invention is to provide a kind of filtering accuracy, filter efficiency all very high fuel oil filter paper and production technology thereof.
The technical solution adopted in the present invention is:
A kind of fuel oil filter paper, comprise percentage by weight greater than 0 smaller or equal to 8% resin, percentage by weight greater than 0 smaller or equal to 5% ceramic fibre, percentage by weight more than or equal to 87% less than 100% wood pulp fibre, the crepe paper that is shaped as accordion of described fuel oil filter paper.The percentage elongation of described fuel oil filter paper more than or equal to 12% smaller or equal to 17%.
Described wood pulp fibre is a needle pine pulp fibres.Described resin is a kind of or its mixture that makes up arbitrarily in phenolic resins, melmac, the acrylic acid modified resin.The fibre diameter of described ceramic fibre is 2～6 μ m.
A kind of production technology that is used to make above-mentioned fuel oil filter paper may further comprise the steps:
(1), measure the wood pulp fibre of above-mentioned weight proportion, add the ceramic fibre and the resin of said ratio respectively, configuration paper pulp;
(2), above-mentioned paper pulp is squeezed, obtain moisture smaller or equal to 55% paper;
(3), the paper after being shaped is carried out drying, must become paper;
Described step (2) afterwards and the paper of step (3) after before squeezing being shaped carry out wrinkling processing.
Wherein, the wood pulp fibre described in the step (1) is a needle pine pulp fibres; The diameter of described ceramic fibre is 2～6 μ m; Described resin is a kind of or its mixture that makes up arbitrarily in phenolic resins, melmac, the acrylic acid modified resin.
In step (1), add before ceramic fibre and the resin, at first adopt method for sieving or washing methods to remove tiny wood pulp fibre; When adopting method for sieving to remove tiny wood pulp fibre, described screening can select for use fractionating screen to divide or the slanted screen screening.
Described wrinkling processing is carried out on the paper machine, described paper facility have press section, drying section and the cylinder between press section and drying section, described press section is provided with scraper, the paper roll that obtains after squeezing is shaped through step (2) is on the cylinder of paper machine, and described paper is wrinkling with the scraper contact position.
Wherein, smaller or equal to 1mm, the press section of paper machine compares more than or equal to 1.12 smaller or equal to 1.20 with the speed of a motor vehicle of drying section the thickness of described scraper in the described wrinkling processing more than or equal to 0.3mm.
In the dry run of step (3) described paper is sprayed glue, described glue is the Organic fluoride polyacrylate.
Beneficial effect of the present invention is: manufacture paper with pulp by body paper is carried out corrugated, increased the filtration space of fuel oil filter paper when multilaminate coiled, make oil circuit unimpeded, not only increased the fuel oil circulation, also increased effective contact area of fuel oil and filter paper simultaneously, improve filtering accuracy and filter efficiency, and prolonged the service life of filter; In addition, by in wood pulp fibre, increasing certain ceramic fibre, improved fuel oil filter paper permeability, reduced the maximum diameter of hole of filter paper, make that the filtering accuracy of fuel oil filter paper is higher, can effectively adsorb and remove the impurity in the oil, improve oil quality and utilization rate, thereby reach effective control discharge of automobile exhaust fumes, reduce the air-polluting purpose.
