    PRODUCTS / AUTOCLAVE FOR RUBBER / RUBBER VULCANIZATION AUTOCLAVES AND RUBBER / RUBBER

    The use of vulcanized rubber in the most technologically advanced industries has become widespread in recent years, going from an accidental discovery to unprecedented industrialization in the automotive sector at the beginning of the 20th century.

    Let’s briefly review its history: During one night in 1839, Charles Goodyear left natural rubber mixed with sulfur on a hot plate; the next morning, said rubber had been converted into elastic rubber, having carried out the first rubber curing cycle in history. This process was patented by Mr. Goodyear in 1843 (but also by Mr. Thomas Cook in the United Kingdom, giving rise to different theories about its invention).

    Since heat and sulfur had been associated with the god Vulcan, this process came to be called vulcanization.

    Autoclave vulcanization is a chemical process applied to rubber and other natural compounds with elastomeric properties, which increases their elasticity and decreases their plasticity, thus improving their mechanical, physical and performance properties such as hardness, viscosity and resistance (mainly to traction and weathering).

    Olmar autoclaves for vulcanization (ATV) allow these processes to be accelerated, allowing natural rubber and plastic (synthetic rubber) to be safely and optimally converted into parts and cured products.

    With application in countless sectors and industrial processes, the exponential growth of autoclaved rubber is mainly determined by its use in:

    • Coating and repair of tires for heavy vehicles, such as trucks and off-road vehicles (OTR – Off Road Tires).
    • Coating and repair of tires for passenger vehicles (SBR – styrene butadiene rubber)
    • Roller coatings on conveyor belts
    • The coating of rollers in printing
    • The manufacture of rubber gaskets for the automotive, aeronautical and shipping industries, radiator hoses, spark plug cables and caps (EPDM rubber).
    • Electrical applications such as insulation of high voltage cables
    • Coating of high temperature cables
    • Manufacture of low, medium and high pressure rubber hoses and sleeves
    • The manufacture of protective rubber covers in which thermal resistance to ozone, weather, corrosive chemical substances or oils are essential properties.
    • Curing of seals and gaskets (O-rings)
    • Others such as mats, boots, etc.

    These products, improved thanks to the autoclave treatment process, will be used in abrasive conditions and/or in extremely corrosive environments, thus extending their life cycle and improving their performance. This result is generally not achievable by standard press-based compression molding.

    The rubber vulcanization autoclaves manufactured by Olmar (called “ATV”) stand out not only for their high level of technological development, but also for their reliability and durability, which guarantee the best performance and the highest levels of efficiency throughout their useful life. The application of rubber in increasingly critical manufacturing elements has brought with it an exponential increase in the demand for control, fatigue and measurement tests of this equipment. Only the most advanced autoclaves can ensure the levels of uniformity and the cycles required by the industry, making R&D investment and continuous improvement ever more important.

    In this sense, since the beginning of its activity within this sector (the company represented Uniroyal in Spain for more than 15 years in the 1970s), Olmar has dedicated a large part of its R&D resources to the investigation of the possibilities of these new materials, being a reference company at national and international level in its study and industrial application.

    CYCLE FOR RUBBER VULCANIZATION

    As we have indicated, rubber is basically an elastomer that can be of natural or synthetic origin (made in petrochemical plants by chemical synthesis), and which is subsequently vulcanized in an autoclave to improve its physical and structural properties.

    In a standard cycle, once introduced in the autoclave, the rubber must reach a temperature of 170ºC (350ºF) and a pressure of 6 BarG (90 psi), remaining at that temperature and pressure for a pre-established time. These conditions may vary depending on the type of rubber and its application.

    It is essential to define correctly with the supplier the maximum time in which we want to reach those temperature and pressure conditions, thus optimizing the productivity that we expect from our autoclave. This data is essential when comparing and aligning different equipment and choosing the most suitable one for our process.

    The variety of existing cycles for the vulcanization of rubber entails the existence of a large number of different types of autoclaves in relation to:

    • Dimensions: Olmar offers autoclaves with a useful Ø diameter from 500 mm. to 10,000mm. , and lengths of 1,000 mm. to 60,000mm.
    • Maximum working temperatures and pressures (up to 482ºF) and 21 BarG (300 psi)
    • Materials: carbon steel, stainless steel or a combination of dissimilar materials
    • Layout: horizontal or vertical

    The most common phases to follow during a vulcanizing cycle are the following:

    1 | Heating and pressurization

    The heating and pressurizing means to be used inside the autoclave are conditioned by the nature of the rubber to be vulcanized and its purpose, with four main modes:

    • Direct steam: through the direct introduction of saturated steam into the autoclave chamber (Olmar is also a reference manufacturer of steam boilers, with more than 1,000 references in the world and >75 years of experience). >
      • In these cycles, the pressurization can be correlated to the temperature of the steam, or carried out independently by introducing compressed air.
    • Indirect heating by introducing steam or thermal oil into an exchanger located inside the autoclave, recirculating the hot air inside by means of a turbine and its motor.
      • In this case, the pressurization is carried out independently by introducing compressed air into the autoclave.
      • The use of hot air instead of steam allows direct contact of the rubber with the steam to be avoided, minimizing moisture infiltration and thus achieving greater adherence of the vulcanized rubber.
    • Indirect heating by means of electrical resistances, recirculating the interior air of the autoclave by means of a turbine and its motor.
      • In this case, the pressurization is carried out independently by introducing compressed air into the autoclave.
      • The use of hot air instead of steam allows direct contact of the rubber with the steam to be avoided, minimizing moisture infiltration and thus achieving greater adherence of the vulcanized rubber.
    • Mixed heating with direct steam | Indirect: An autoclave developed by Olmar to be able to work with the best of both technologies at all times, according to needs.

    2 | Stabilization phase

    Once these target conditions (temperature and working pressure) have been reached, we must maintain them for the minimum time established during the stabilization phase, which is carried out fully automatically thanks to the OCS (Olmar Control System) control system equipped with Siemens PLC technology. or Allen Bradley.

    3 | Cooling

    As in the heating phase, the cooling and depressurization means to be used inside the autoclave are conditioned by the nature of the rubber to be vulcanized and its purpose, with three main modes:

    • Natural cooling: the autoclave cools naturally as the steam inside is extracted.
      • In some cases, it is necessary to compensate for this depressurization by introducing compressed air to guarantee an optimal finish of the product.
    • Cooling by shower or spray: the autoclave is cooled by water introduced from the top of the autoclave and sprayed on the product by shower or spray.
    • Indirect cooling: this system is based on the introduction of cold water in an exchanger located inside the autoclave, recirculating the air inside the equipment by means of a turbine and its motor.

    TYPES OF CYCLES FOR TIRE VULCANIZATION

    1| By direct steam

    Once the autoclave is loaded, pressurized saturated steam is introduced, subjecting the tires to the programmed temperature and pressure conditions.

    2| By indirect heating

    In this type of cycle, each tire is encased in an “envelope” (rubber cover) which in turn has a valve through which it is possible to introduce compressed air to press it.

    Once the autoclave is loaded, the hoses are connected to the envelopes in order to provide them with pressure during the cycle.

    As we have explained previously, in this case the hot air is obtained through the recirculation of steam or thermal oil in an exchanger, or also through electrical resistors. As the internal temperature rises to 125ºC (290ºF), the envelopes inside the tires are inflated and pressure is introduced into the autoclave (with a difference of 2.1 BarG (30psi), until the chamber reaches a pressure of 5, 5 BarG (80 psi) and tires at 8 BarG (115 psi).

    At that moment, the envelope that covers the tire is pressurized up to 4.2 BarG (60psi); This pressure is generally called “third pressure” and it guarantees optimal bonding and a better tire finish.

    This part of the process usually lasts approximately 120 to 150 minutes.

    Once the previous stages have been completed, depressurization is carried out in the following order:

    • Third pressure
    • Tire pressure
    • Autoclave pressure

    THE “SMART” AUTOCLAVE WITH REVOLUTIONARY CONTROL SOFTWARE

    Precision and reliability are fundamental factors within the rubber manufacturing processes. The high level of demand in the automotive and construction sectors requires thorough monitoring and control of all the processes taking place inside the autoclave. In this sense, Olmar has developed the most advanced software in the world for rubber vulcanization autoclaves, thus meeting its goals of digitization and efficiency in manufacturing processes. This is, in short, an intelligent autoclave, capable of automatically controlling heating in its different modes, pressurization with air or saturated steam, maintenance of vacuum, pressure and temperature values ​​during curing and subsequent cooling and depressurization, allowing control and parameterization of each of the manufacturing phases. All this allows us to achieve optimal vulcanized rubber, both in finishes and properties.

    It is important not only to control and analyze these values (pressure, vacuum and temperature) during the cycle, but after it as well. By studying the data collected during the process taking place inside the autoclave, we can detect possible points for improving and optimizing the cycle. Olmar offers its customers optimized features through a control system fully developed in-house by the company’s electrical and software departments. Furthermore, its innovative reporting technology provides the most accurate data control and analysis on the international market, showing its strong commitment to developing what is known as “Industry 4.0” and using all available innovations on its autoclaves.

    Olmar has ultimately concentrated all of its efforts on the creation of an “intelligent” autoclave, focusing its developments on the areas of energy efficiency, usability, predictive control and low maintenance.

    Its OCS (Olmar Control System) control software integrates all these functionalities, reducing the consumption costs of the autoclave, improving its productivity and optimizing any periodic maintenance task to be carried out.
