Usage methods： First we should confirm whether the specifications of inner tube and outer tube are the same, then check whether the valve core, nut ,dust cap and other accessories are complete. Before installing the inner tube, please carefully check the outer tube cavity whether there are sand and other sundries, whether there are cracks or other adverse factors, if there are , should be eliminated first .When installing the inner tube, pay attention not to twist the inner tube. Check steel rim carefully, which should have no deformation, bending,bur and other adverse factors. When fitting steel rim with the assembled inner&outer tube, please use special tools (don’t use sharp instruments, such as screwdrivers which might damage the inner or outer tube bead toe ). Please confirm the cycle valve being locked on the steel rim properly and being out of the steel rim to inflating conveniently .At the same time, pay attention not to sandwich inner tube between outer tube and steel rim . After fitting the the assembled tyre with steel rim, the tyre should be inflated slowly to put a little pressure on the tyre. And then stop inflating, check whether there is sandwiching tyre problem. After confirming normal, please continue to inflate until reaching the standard pressure(refer to outer tube profile ). Finally lock the valve core and dust cap .Storage methods:The inner tube should avoid to be mixed packing & storage with oil, other organic solvents, flammable materials, chemical and corrosive substances, which will lead to inner tube aging.The inner tube should avoid to be piled up in open-air, direct sunlight and rain, as well as where ozone often being produced (such as sterilization lamps, electric welding machine and other devices that producing sparks）.The inner tube storage should avoid the deforming state being created.
The methods to recognize the butyl rubber inner tube : The inner tube body has color line with width no less than 2mm .1. Butyl rubber inner tube, there should be blue line on its circumference.2. Butyl rubber and halogenated butyl rubber inner tube , there should be green line on its circumference.3. Butyl rubber and EPDM rubber inner tube, there should be red line on its circumference.
INNER TUBE DESCRIPTION ：The specifications of butyl rubber inner tube and the specifications of natural rubber inner tube are the same. Butyl rubber has a series of advantages because of its high saturation of the molecular chain. The butyl rubber not only has low permeability rate and good air tightness, but also has good heat aging resistance, ozone resistance, chemical corrosion resistance and absorb the vibration. The butyl rubber is the best raw material for manufacturing in the inner tube .
Curing Bladder Production Processing Technology : Currently, there are two processing technologies for curing bladder production, one is molded type curing bladder and the other is injection type curing bladder.1. Characteristics of molded type and injection type curing bladder : Production Processing Technology Characteristics Molded Type Curing Bladder The semi-finished curing bladder are placed in the seam between the upper and lower molds.,when the mold is installed, the upper core mold rises and the lower core mold drops. The upper and lower core molds run rubber material seriously, so the quality of semi-finished curing bladder cannot be controlled, which is easy to cause the phenomenon of non-compactness and uneven thickness of rubber materials. Injection Type Curing Bladder Through a serious of automatic control steps of the machine , the injection type curing bladder has advantage of compactness and even thickness of rubber materials. 2. The advantages of injection type curing bladder:The heat transfer of injection-type curing bladder is faster than that of molede type curing bladder, which can shorten the curing time of tire production, so as to improve production capacity and reduce energy consumption.At the same time, the injection type curing bladder has better aging resistance and long service life.

How to improve the service life of curing bladder： Tire curing bladder is used for tire vulcanization, whose life has been concerned by the tire manufacturers , not only with the tire quality and tire production costs but also the tire production efficiency are closely related.From the beginnig of the curing bladder replacement, to the replacement of the first stove production, its consumption of time at least 30 minutes.In this paper, the usage management of curing bladder ( storage conditions, operation sepcifications, pre-treatment before use, deoxygenation of vulcanized media ), as well as the selection of curing bladder specifications, curing bladder surface patterns and other measures are taken to describe how to improve the service life of curing bladder.1. Choose the curing bladder with injection processing technology2. Choose the right size of curing bladder3. Curing bladder surface pattern selection4. Strengthen curing bladder use management5. Standardize curing bladder replacement operation
General Information: Tyre building bladders are rubber parts like turn up bladder, push over bladder and so on mounted on tyre building machines to support the green tye building process.If you are intersted in rubber parts, please contact us.We will find the right product for you.If you have TBM ( Tyre Forming Machine) drum or bladder drawing, we accpet customization and OEM.
General Information： Curing is the process of applying pressure to the green tire in a mold in order to give it its final shape, and applying heat energy to stimulate the chemical reaction between the rubber compounds and other materials. In this process the green tire is automatically transferred onto the lower mold bead seat, a curing bladder is inserted into the green tire, and the mold closes while the bladder inflates. As the mold closes and is locked the bladder pressure increases so as to make the green tire flow into the mold, taking on the tread pattern and sidewall lettering engraved into the mold. The curing bladder is filled with a recirculating heat transfer medium, such as steam, hot water, or inert gas.At the end of cure the pressure is bled down, the mold opened, and the tire stripped out of the mold.
