Then the completed green tire, with the vulcanizer bladder unit, is assembled in a vulcanizing mold for vulcanization and forming.
The vulcanization apparatus heats a green tire and achieves vulcanization molding thereof.
The present invention relates to the process for vulcanization of said polymers with said vulcanization mixture.
Thus, the tire vulcanizing process can sufficiently inhibit the generation of porosities without prolonging the vulcanization time, thus enhancing the productivity in vulcanization.
Premature vulcanization taking place during the process prior to vulcanization.
A process for the vulcanization of a rubber composition, and articles of manufacture where the vulcanized rubber comprises the vulcanization reaction product of the vulcanisation process of the invention, are disclosed.
A tyre enclosed in a vulcanisation mould (3) is supplied with heat to cause vulcanisation of same.
The green tyre (2) engaged on the expandable toroidal support (23) is introduced into a vulcanisation mould (30) and submitted to a vulcanisation cycle.
The green tyre (2) engaged on the expandable toroidal support (10) is introduced into a vulcanisation mould (29) and submitted to a vulcanisation cycle.
The invention relates to a rubber vulcanisation method which includes preparing said vulcanisation composition and the vulcanised rubber obtained thereby.
The present invention relates to curing of polymers, particularly to self curing of polymers.
In particular, the auxiliary composition enhances the rate of cure at elevated temperature, and retards curing at room temperature.
Component (D) is a curing agent.
Component (E) is a curing agent.
The invention relates to a device and to a method for adjusting the height of a mould of a tyre curing press, and to a tyre curing press.
The cure package permits the elastomeric compound to achieve a ninety percent cure, at a cure temperature of 120 °C, in less than 30 minutes.
Where the reactive silicone component cures by way of an addition cure mechanism, an addition cure catalyst is also included.
Subsequently, the elastomer is cured at a higher temperature, causing vulcanization.
Preferably, the product is cured in a warm, moist environment.
Good results for under cure adhesion have been obtained.
What is proposed is a process for joining conveyor belts which contain metal inserts by vulcanization, and also a corresponding vulcanizing press.
A fluoroelastomer is produced by vulcanizing the above copolymer.
The invention disclosed herein relates to methods for vulcanizing elastomeric materials.
The fluoroelastomer has improved vulcanization characteristics, and there is a wider choice of vulcanizing agents with which the elastomer can be vulcanized.
Various known vulcanization activators may be added to this vulcanizing system.
The rubber is then vulcanized.
A vulcanization mold with an inner-layer apparatus (2) includes a vulcanization mold cavity (1).
The additive can be especially sulphur or another vulcanising agent, a vulcanising accelerator and/or an activator.
The use of sulfur to vulcanize the polymer blend is not necessary.
A tire vulcanization device (1) heats and vulcanizes, within a vulcanization mold (10), a tire (90) not yet vulcanized.
Also disclosed are a sulfur-vulcanization process carried out in the presence of these metal salts and the product of said vulcanization process.
Thus, the vulcanization-molded tire is taken out.
bladder mould for vulcanising tyres
An acrylic rubber composition which has excellent storage stability before vulcanization, is less apt to scorch during vulcanization, and gives a vulcanizate reduced in compression set and in thermal change in material property.
Once the penetrator is introduced into the sabot (1), the second joints (11) are closed with a vulcanized material by vulcanization.
Application of heat causes exposed areas to be vulcanized.
The nitrile rubber thus obtained is capable of giving vulcanizable elastomeric compositions having a high vulcanization rate and a good vulcanization yield.
In this state, vulcanization molding is carried out.
The use of the solid particulate substrate in the vulcanization of rubber reduces the amount of transition metal oxide used in the vulcanization process.
This composition is favorable for vulcanization.
