Abstract
The invention provides with an epoxy resin drawing knife and its producing technique. The technique is: a) prepare liquor resin glue by the contents' ratios of weight: 501 epoxy resin taking 40 to 55 shares, electron pole dicyanamide taking 4 to 15 shares, formamide taking 8 to 12 shares, graphite powder taking 1.5 to 3 shares, quartz powder taking 1 to 5 shares; b) dip the multi-layer fiber in the glue, heat, press and solidify the fiber; c) process with machine by the size requirements. The drawing knife has a cutting edge at one side of the blade lengthwise with an include angle of 25 to 55 degree. The epoxy resin drawing blade produced with this method has advantages such as high temperature resistance, super-long drawing blade, high plainness and rigidity, the cutting edge is easy to shape. The angle and thickness of the cutting edge is rationally designed with a small abrasion coefficient with the baking cylinder of the paper machine and pressing roller which does no cuts on the roller so to lessen the machine halting idle for roller replacement which lowers cost and increase income.
Description
Technical field
The present invention relates to a kind of method for manufacturing epoxy resin scraper and products thereof, belong to paper making equipment design and manufacturing technology field.
Background technology
At present, the used scraper of papermaking equipment is band saw steel disc scraper or phosphor bronze sheet scraper, because band saw steel disc and phosphor bronze sheet are hard, it is serious in process of production the drying cylinder in the paper machine, felt wrapped roll to be drawn mill, make drying cylinder, calender roll surface radially rill occur, shortened the service life of drying cylinder and felt wrapped roll, and make the paper web soft or hard of production irregular, paper often breaks end in the production, influences the quality and the production of product.Other has a kind of adhered scraper, surpasses 2.5m, must be bonding, and the abutting edge is shaky, and globality is poor.Also have a kind of cloth matter phenolic aldehyde scraper, though overcome the problem of stroke mill drying cylinder, felt wrapped roll, because of intensity is low, blade thickness is increased, friction strengthens in process of production, and the effort of taking a lot of work is uneconomical.
Summary of the invention
The purpose of this invention is to provide a kind of method for manufacturing epoxy resin scraper, this method is reasonable, practical, can obtain flatness height, intensity height, ABRASION RESISTANCE is strong, pliability good, resistant to elevated temperatures epoxy resin scraper.
The objective of the invention is to realize by following technical solution.A kind of method for manufacturing epoxy resin scraper is characterized in that,
A) obtaining liq resin glue, its composition weight umber ratio is:
501 epoxy resin 40-55 part electron pole cdicynanmide 4-15 part formamide 8-12 parts
Graphite powder 1.5-3 part silica flour 2-7 part pearl powder 1-5 part;
B), heat, pressurize and make and curing with the multi-layer fiber cloth impregnation;
C) carry out machined by dimensional requirement.
In the said method, described cloth is basalt fiber cloth, carbon cloth or alkali-free glass fiber cloth.
In the said method, described heating-up temperature is 220-240 ℃, and pressure is 3000 tons.
Another object of the present invention provides a kind of epoxy resin scraper that adopts above-mentioned manufacture method to obtain, in order to replace band saw steel disc scraper or phosphor bronze sheet scraper.Its intensity height, high temperature resistant, be integral structure, have ABRASION RESISTANCE and pliability.
The objective of the invention is to realize by following technical solution.Design a kind of epoxy resin scraper, its scraper one or both sides along its length is provided with cutting edge, and cutting edge and horizontal plane angle are 25-55 °.
In the such scheme, described blade thickness is 2-10mm, and preferred thickness is 3-5mm.
In the such scheme, described scraper width is 80-150mm.
The epoxy resin scraper that manufacture method of the present invention obtains has the following advantages:
1, high temperature resistant, can reach 300 ℃ indeformable.
2, scraper overlength, but 6.5-20m non junction.
3, flatness height, 10 error of meter are no more than 10 millimeters silks.
4, intensity height, its reality that is of close texture, and the coefficient of friction between paper machine dryer, felt wrapped roll is little, does not damage roll surface, reduces and shuts down the roll change number of times, high-strength wearable, the hardness unanimity adds aliquation, phozy not in man-hour, the easy machine-shaping of cutting edge.
5, scraper blade angle, gauge are reasonable in design, are applicable to production.
