Abstract
The invention discloses a method to remedy artificial stone roll surface, which belongs to facet of paper making device. The specific method is: The surface needing treating is roasted to dehumidify and clean by using cleaning agent. Mending spot of roller is milled by gas mill head to bare fresh surface, which then is filled glue, solidified and grinded to shape. The method has short remedying period and low remedying cost.
Description
The invention relates to the repairing technique of papermaking equipment equipment.The artificial stone roll is mainly used in the nip and the german press position of paper machine squeezing rear portion dehydration, plays the ornamenting effect that improves l Water Paper page frame table smoothness.The artificial stone roll is bag one deck artificial composite material on roller core, and the composition of this artificial composite material mainly is the very thin quartz sand powder of rubber and granularity.
Artificial stone roller surface just need be repaired by the serious scratch of scraper or by after the seriously crowded wound of hard thing.Usually the method for repairing is: the artificial composite material layer car that is wrapped fallen, recover to use by the mode of kiss-coating again then.This method is repaired an expense generally more than 100,000 yuan, and be one month repair time.This restorative procedure cost height, and the cycle is long.
The present invention adopts epoxy resin structural adhesive (Araldite2014) and special fix-up technology that the major injury of artificial stone roller surface is repaired.Use the patched roller of method of the present invention, can satisfy the requirement of production technology, expense and the repairing cycle of saving again kiss-coating are short.
Technical process: 1, injured surface is handled: use the baking instrument that injury region is toasted, the time was toasted the surface and is kept about 50-60 ℃ of temperature more than 10 hour, treated the moisture of the material internal certain depth of injury region with drying; Notice that temperature can not be above 60 ℃ during baking in order to prevent that glue-line is aging.Before by the roasted material cooling, the pair of rollers injured surface cleans greasy dirt with cleaning agent; With the gas milling head that cleaned through cleaning agent, milling roll damage surface reaches all to be seen newly; Blow off chip under the milling with hand-held hair dryer.Injury region drying, cleaning, bond area decision healant with by the effect that combines fastness and repairing of patching material.In above cleaning, milling, blowing process, repaired the position, be in all the time by the baking state to keep temperature.
2, filler, this process comprises and is coated with primer, two parts of face glue, the mixed method of primer, face glue is: the supply status of Araldite2014 glue is two-tube A, B glue, the glue rifle that use matches with identical stroke is clamp-oned glue-mixing tube simultaneously with A, B glue from sebific duct, the proportional quantities that is extruded A, B glue just in time is the ratio that mix.If the glue rifle that does not match is then according to the volume ratio of white size and grey coloring agent=be mixed at 2: 1.Because the density of A, B glue is identical, also can use balance according to the weight ratio of white size and grey coloring agent=be mixed at 2: 1.It is identical with the ratio of face glue to mix the system primer, all is according to above-mentioned volume ratio or weight ratio=2: 1.
Then homemade T font specific purpose tool is stuck in gas and mills, the rotation of milling by gas mixes glue, when mixing the system primer, notice that the rotating speed that gas mills is suitable, tries not air is sneaked into.When mixing system face glue, gas mills stirring and carries out high rotating speed more than 3000 rev/mins as far as possible, in the hope of air is stirred in the glue, and makes the air that stirs in the glue form air bubble a large amount of, small, that the disperse degree is very high in glue.Such glue-line forms similar stone roll or artificial stone roll's the paper of releasing after solidifying.Mixing the glue process should finish within 5 minutes, and it is just qualified to reach abundant mixings of color even in appearance, and this is that chemical reaction of guaranteeing glue curing can fully carry out and one of basic condition of indispensability.The coating of primer also claims bottoming, the painting method of primer, and the primer that uses the less scraper in cross section carefully will mix at full tilt waiting to be coated with scratch on the face of repairing watch back and forth, is soaked into by healant to guarantee this surface repeatedly fully.Primer only needs very thin blade coating one deck to get final product.After primer completes, just begin to be coated with face glue, the face glue that mixes is coated onto on the surface of primer, reach the thickness that needs always.Filler enters cure stage later on, this process comprises two steps of primary solidification and back curing, primary solidification: can take the method for local heat to make its environment temperature reach 20～45 ℃ (if environment temperature is between 20～45 ℃, then do not need heating) scope, solidify and can reach primary solidification in 24 hours.Solidify the back: after primary solidification is finished, with the baking instrument it is warmed up to 80 ℃, keeps this temperature 24 hours with further raising state of cure.Warp is solidification process later, and every performance of healant will improve 20-50% again.After the curing, instruments such as use file carry out preliminary finishing to repairing the position surface configuration, roller is delivered to done further reconditioning on the grinding machine then, make its surface reach the geometric accuracy requirement, just can use by above paper machine then.
Embodiment one, toasts and uses the super bath lamp to toast in the process on pending surface, makes its temperature reach 50-60 ℃, more than 10 hours with dry moisture.Employed cleaning agent is 1755 in the cleaning process.Be coated with before the primer, the temperature of waiting to repair the position will be higher than glue and solidify required temperature 5-10 ℃.Primer only needs very thin one deck to get final product, and all the other are face glue.After completing glue, be cured, after curing is finished, reconditioning carried out on its surface made it reach the geometric accuracy requirement, just can come into operation.
Claims (1)
1. the method for repairing and mending of the artificial stone roller surface of a paper making equipment aspect, this method is made of the following step:
