Abstract
The present invention relates to a process for renovating the waste tyres of military airplanes and a novel application thereof. A technology for renovating ordinary tyres and a tank type vulcanizing technology for producing new tyres are comprehensively utilized, and main technological conditions are improved. The renovated waste tyres of the military airplanes are matched with special wheel rims and used on engineering vehicles for obtaining optimal economic benefit. The renovating process comprises the working procedures of tyre selection, washing, crude grinding, side grinding, repairing, dust removal, process check, drying, slurry spraying, baking, hot sticking, tyre baking, tank type vulcanization. Compared with the tyres of the engineering vehicles, the renovated tyres have the advantages of cost reduction, long service life and obvious effect on repairing the old and utilizing the waste.
Description
The invention belongs to useless, old tire renovation field, particularly scrap the renovation technology of military aircraft tire.
In the tire of all kinds, purposes, requiring of characteristics that the high load capacity of military aircraft tire, good, the anti-stabbing of resistance to impact are strong and engineering tyre is close, possesses the good strong point of resiliency and shock absorption again.Aero tyre is scrapped the back or surpassed the expired tire of storage period does not all have rational purposes at present, unfortunate really as refuse.If the military aircraft tire that uses the renovation of aircraft tire renewing technical conditions to scrap, though product quality can guarantee that costly, and production efficiency is low, cost is high, product loses competitiveness; If use the reconditioning technology condition of general tire, product then is difficult to reach instructions for use.
The objective of the invention is to scrap the no suitable purposes in back and do not have suitable renovation technology, provide a kind of and scrap military aircraft tyre rebuilding technology, and it is used on the engineering truck at existing military aircraft tire.
Technical scheme of the present invention is such.To utilize the reconditioning technology of conventional tyre and the tank type vulcanizing technological synthesis of the new tire of production, and the main technique condition is improved, the military aircraft tire of scrapping after the renovation is prepared special-purpose wheel rim, and it is used on the engineering truck that obtains optimum economic benefit.Its renovation technology comprises and selects tire-wash tire-big mill-side grinding-finishing-dedusting-process check-drying-whitewashing-heat posted to close-dry by the fire tire-tank type vulcanizing operation that this renovation technology is that the appearance of tire is all renovated, increase sidewall, tread rubber gage.It is with compacting again after hot carcass after the oven dry and the applying of hot glue sheet that heat posted in the renovation technology is closed operation.Its tank type vulcanizing operation adopts high interior pressure, many punching blocks, autoclave press sulfuration process, presses in vulcanizing to be 2.5-2.8MPa, carries out abundant cooling and shaping inside and outside the model after vulcanizing.Because the military aircraft carcass is hard, on the military aircraft tire of scrapping, use the aero tyre wheel rim to involve great expense and easily assembling not.Therefore, through the special-purpose engineering truck wheel rim of carcass preparation of renovation, wheel rim is manufactured the dimensional tolerance by instructions for use, former tire size, engineering wheel rim, and design and manufacture becomes divided type rim, is used for engineering truck.
The present invention has following advantage:
1. adopt improved conventional tyre reconditioning technology to scrapping the military aircraft tyre rebuilding, prepare special-purpose wheel rim and be used for engineering truck, can reach and repair the old and utilize scraps,, remarkable social benefit is arranged for society saves the purpose of producing the new tire and the energy.
2. the military aircraft tire after the renovation is compared with the engineering truck tire, and single cover tire purchase price can reduce 30-50%, and can double service life, and user's tire usage charges reduce more than 60%, and have reduced maintenance capacity, and remarkable economic efficiency is arranged.
Embodiments of the invention are as follows:
Renovation technology of the present invention is that common carcass treatment technology is combined with the pot type multimode sulfurization technology of producing new tire, makes adaptive improvement on technology: employing remoulding mode, heat posted close, dry by the fire tire and the many punching blocks of autoclave press vulcanize, the inside and outside fully cooling of model.Each operation main points is as follows:
(1) selects tire: select tire according to the cross-ply first class renovation carcass condition in the renovation full capping national standard, but do not allow the crown Durchgangshohle.
(2) wash tire: remove tire inside and outside earth, foreign material.
(3) big mill: use hydraulic tire chiselling machine, grind off the old surface rubber layer of tire.
(4) side grinding: use wheel shaft sander polishing sidewall, wire wheel hacking rim of the mouth.
(5) finishing: the cord head that uses scissors, wire brush to remove unsteady collodion silk and expose.
(6) dedusting: glue foam, the impurity of cleaning flour milling.
(7) process check: by the half-finished quality requirement of each operation, the carcass of processing is checked one by one, prevented that underproof semi-finished product from flowing into operation down.
(8) drying: to the dry moisture content of the qualified carcass of size, the excessive person of carcass is 80
± 10℃ temperature under heated respectively 30-60 minute, make the nylon carcass under the thermal contraction condition, it is close that appearance and size reaches basically, the sulfuration of the punching block of unified size easy to use.
(9) whitewash: the rubber cement that used 1: 9 sprays one time, and dried 5-8 hour down at 35-45 ℃ the spray back, takes advantage of heat to fit.
(10) heat posted is closed: hot carcass after the oven dry and hot glue sheet are fitted, compacting thereafter.
(11) baking tire:, adorn and dried by the fire tire 6-12 hour down at 40-45 ℃ earlier before mould vulcanizes for guaranteeing the presentation quality of remoulding tire.
(12) tank type vulcanizing: the equipment that this operation is used is autoclave press, superheated water device and steel mold.Sulfurating stage divides intensification, boost phase, optimum cure stage and cooling stage.Boost, the temperature rise period: curing bag over-heat inside water 0-2.5MPa pressure, temperature is 120
± 5℃, model external steam pressure is 0-0.35MPa, temperature is 145
± 2℃, this time in stage is 20 minutes; The optimum cure stage: curing bag over-heat inside water 2.5-2.8MPa pressure, temperature is 120 ± 5 ℃, model external steam pressure is 0.35
± 0.01MPa, temperature is 145
± 2℃, the time is 50 minutes; Cooling stage: curing bag internal pressure 1.0-1.5MPa, temperature is a normal temperature, and the model outside running water that lets off steam soaks the mould cooling, and the time is 20 minutes.
Because the military aircraft carcass is hard, on the military aircraft tire of scrapping, use the aircraft wheel rim to involve great expense and easily assembling not, therefore, through the special-purpose engineering truck wheel rim of carcass preparation of renovation.By the dimensional tolerance of instructions for use, former tire size, engineering wheel rim, the design and manufacture divided type rim is used for engineering truck.
