Background technology
Be that automobile, aircraft, building machinery or agricultural machinery are all used retreads widely at present both at home and abroad, one of its major reason can be reduced expenses exactly in a large number, thereby reduces operating cost, and general retreads approximately can be economized 30%～50% expense.After motor transport service and the appearance of tire manufacturing industry, the tire vulcanizing industry also produces in succession.Replace on the market at tire, the shared proportional increasing year by year of retreads, tyre retreading technology, output and quality are also all improving constantly.
Tyre rebuilding has formed industry in China, and production capacity mainly concentrates on the cross-ply, and kind comprises engineering tyre, aircraft tyre and high-capacity tyre.Though China is the third-largest state of world's tire production, a year tyre retreading amount only is 3,000,000.China's tyre rebuilding amount is about 3% with the ratio of new tire amount, and the level far below the world average 7% also is lower than China Taiwan.If calculate by the accessible refresh rate of various Off-the-road tires of early 1990s 12%, China's Off-the-road tire tyre retreading in 2005 amount should be about 4,000,000, but sizing material and equipment that China also will use from national import retreads such as most active Malaysia of Asia tyre retreading industry and Singapore now.
Owing to the great demand of states such as China, Russia, Indonesia to engineering tyre, the whole world is the critical shortage of specification engineering tyre greatly over the past two years, and this phenomenon will continue after 2005.
The engineering tyre critical shortage is tiremaker and dealer's a consensus.Even whole world engineering tyre full production in 24 hours in a day at present, it supplies with also almost zero growth potentiality.The demand of engineering tyre in 2004 increased by 20% than 2003, and this in the industry cycle is unprecedented in history.Engineering tyre shortage in 2004 is because due to the tire consumption increase, domestic and overseas growth of requirement causes the engineering tyre critical shortage.
The engineering tyre shortage has had a strong impact on mining industry, building industry and other industries.The reason that causes the engineering tyre shortage is demand huge increase of market to ore especially coal, carbon, iron ore, copper, nickel and alum etc., causes the digging ability to expand.The huge driving force that increases of the ore market demand is mainly from fast development of Chinese economy, secondly from Russia and Indonesia.The huge market of extractive industry is to the demand sharp increase of novel digging bogie and equipment.All come into operation now again in engineering bogie that past stops work and the mine of closing.
The method of both at home and abroad Off-the-road tire being renovated mainly contains at present:
1), knock over new: the tyre crown good mill partly gives precured tread on heat posted or the cold bonding, and this method glue consumption is minimum, and tire deflect a little on do not have joint;
2), sulfurizing pot vulcanization: capsule fills superheated water, the sulfuration of interior pressure;
3), pressure tyre surface tyre retreading method:, tread mix directly is pressed onto on the carcass that ground, and forms tread contour simultaneously by extruding the head of the shape of the mouth as one speaks;
4), belt is transplanted and the engineering tyre pattern block is repaired replacing: transplant same specification and scrap the decorative pattern of tire tread block with full capping, also available mould is done new pattern block, and through big mill processing, coating adhesive is pressed onto on the carcass that ground.
The Off-the-road tire renovation has following advantage:
1), make full use of regenerated resources, reduce environmental pollution, improve existent environment of people;
2), price advantage, this also is the advantage places of retreads with respect to new tire maximum.Generally speaking, the price of retreads only is 20%～50% of a new tire;
3), safe and reliable.In the many countries of America and Europe, almost hundred-percent engineering truck uses retreads.World car the expert think: the engineering truck retreads can travel according to the same regulation speed of new tyre, on safety, performance and level of comfort not second to new tire.Facts have proved that the engineering truck retreads are safe equally, durable with new tire;
4), market potential is huge.Along with the huge fast development that increases of China's ore industrial market demand, its corresponding effect of bringing is the wilderness demand of Off-the-road tire, but because present engineering tyre whole world critical shortage must cause the renovation industry fast development of waste and old Off-the-road tire.
For heavy construction vehicle tyre renovation, traditional renovate method is to adopt the rounding type vulcanizer to vulcanize or stick the tyre surface of strip with the tyre surface machine of posting, and engraves decorative pattern then and is placed into sulfurizing pot vulcanization again.The method that adopts the rounding type vulcanizer to vulcanize drops into higher relatively at the cost of mould, process-cycle is long, and want corresponding supporting large-scale sulfidization molding production line, its cost input is very high, and employing strip tread contour rubber strip method, except die cost higher relatively and process-cycle long, the banded tread contour rubber strip of compacting also requires supporting relatively large equipment, this is very heavy financial burden for the tyre rebuilding producer of general scale, therefore, adopt methods such as rounding type vulcanizer or belt-tread pattern rubber bar under the environment of present global large off-the-road (OTR) tire critical shortage, not satisfy market demands.
