 Main technical features are as follows:

 

Main technical features are as follows:The material of carcass and belted layer are all the strong strength wire connection.Directionof the former one is radial ,small angel of belted layer hoped strong force to the steel wire connection of carcass ,therefore it bears 60%-70% loading .Structure of belted layer is 0℃, Both ends supported with underlying triangular rubber ,belt layer approaches lever line with ground.Both sides of the third layer also have two layers of 0℃,hence improved both the high speed and wear-resisting performance.The use of wear-resisting rubber in touch place with tyre rim ,improved the protection of tire bead ,reduced the damage to the rim .

We have made some optimizing recipe designs accoding different stress of differ parts.Between –between or between –white-cobalt adhensive system ,oil-free formular and so on ,such designs make the steel cord fabric rubber up to the best bonding effect ;furher more, all-nature rubber ,super wear –resistance of carbon black or blend use of white carbon black and silane ,such designs highly improved the wear-resisting and tear-resistance performance.

 

Since different structure of all steel radial load tyre and bias tyre ,of course they have remarkable different manufacturing process ,hence raised more higher requirement to the craft quality .The refine of rubber film using multiple mixing,meanwhile controlled the result with diversity ;steel rolling process using brand new lines of production ; demand to the stability of the process for rubber parts are more higher ;bead wire using single wire forming,wraping,gum dipping,application,such kind craft is quite complex;molding process using unstage building machine of steel radial tyre ,position accuracy of all parts remarkablely improved a a lot ;vulcanization process using the double die vulcanizing process with adjustable die .After vulcanization ,every finished tyre must be examined by X-ray except for appearance inspection.Comparing with the like product in domestic,our tyre tread using such technical designs of layered composite tire crown and reduce-thin tire crown ,thus effectively reduced the proportion of tyre shoulder empty fault;meanwhile the replace of low cis butadiene rubber (original is cis-rich butadience rubber )largely reduced the design cost ,improved the vulcanizing qualified rate,and relieved the pressure of low cis butadiene rubber importing.Our product performance places the leading level in domestic .Each index of our all steel radial tyre fit state standard GB9744—2008 ,strength character and durability test are over 100 hours ,which particularly higher than the state standard of 47 hours only .

 

In recent years ,since the development of transportation business ,heavy duty truck and commercial vehicle developing fast ,heavy demand of heavy loading tyre stimulate the development of heavy loading steel radial tyre ;besides,such tyre reflected in the maintenance market , through practice our customers have realized (by practice )the good advantage of steel radial tyre ,especially the long distance and mass transportation ,more reflect good features of TBR tire .Therefore,now present not only the market are increasingly replaced by TBR tyre but also improved the step of the change from bias tyre to TBR tyre.TBR tyre have applied the truck and bus’s requirement of high speed ,it has high speed ,safety,wear-resisting,long mileage,riding comfort,fuel-efficient and other merits,for these reason ,TBR tyres are more and more popular among the drivers friends .The structure of TBR is the direction of tyre development,at present ,the proportion of TBR tyre have been up to 90% in the whole world,but the level of such superior tyre in our own country is still so low ,we state have wonderful development prospect .

 

 

 

 

Along with the increasingly fierce of market competition ,in order to promote the new tyre product’ research and development ,meanwhile for speeding up the renewal cycle ,what we can do is only improve ourselves’R&D ability and managing capability ,only by this we company can place in the strong power position of worldwide tyre.We company TBR tyre have high starting point ,we imported the advanced technology of Italy pelili,on this basis ,we have purchased the most advanced molding machines、internal mixers and other key equipments ,we have built up the best production lines of TBR tyre in our country ,on the aspect of hardware ,such management and producing system promised the stability of TBR tyre quality .At the same time ,our continuously development on New TBR tyre ,not only satisfied the needs of increasingly improved market in both home and abroad ,further improved we company’s market competition ,but also obtained remarkable economic benefit.On one side,the tubeless change、flattening(including meridian change)is the tendency of tyre development ,we company are actively developing and perfecting the specification of radial tyre,in order to apply the market demand ;on the other side ,the present market prospect are so optimistic that we company put our hands to continuously develop beautiful and novelty patterns,new products meet the sales way,thus actions enhanced the popularity and market competition ability of our company .
