Description

This machine is designed to get the characteristic curve and characteristic parameters of rubber vulcanization by measuring the applied moment of rubber to the oscillating dye body. NG-ODR rotor-free vulcameter has an excellent stability of results. The data and diagrams can be used as a reference for development, research and production quality.

NG-ODR describes precisely and quickly the curing and processing characteristics of vulcanized rubber compounds. It works on a very simple principle. A test piece of rubber compound is contained in a sealed test cavity under positive pressure and maintained at a specified elevated temperature. A Rotor (oscillating disc) is embedded in the test piece and is oscillated through a small specified rotary amplitude. This action exerts a shear strain on the test piece and the torque (force) required to oscillate the disc depending on stiffness (shear modulus) of the rubber compound.

FAQs

While maintaining or even increasing the elastic qualities of rubber, vulcanization reduces its plasticity. In the past, the term "vulcanization" was primarily used to describe the reaction between sulphur and rubber, but it is now typically used to describe any process that modifies a material's characteristics, whether it be caused by sulphur or another substance.

Practical vulcanization techniques rely on the transfer of heat from the exterior to the inside of the object being cured. Since compounding adjustments cannot significantly alter the heat conductivity of realistic rubber compounds, increasing temperature is a frequent way to hasten the vulcanization process. The most recent curing or moulding techniques, like injection moulding, the liquid curing medium (LCM) method, and microwave curing, employ higher curing temperatures.

NextGen’s Oscillating / Automatic Disc Rheometer (ODR weights 498lbs / 226kg, has the following dimensions: 51.5x22x24.4" / 131x56x62cm, and power: 110V/60Hz or 220V/50Hz 1000 W

If the vulcanization temperature is raised when silicone rubber products are being moulded, both the vulcanization time and efficiency can be effectively increased. As a result, many vulcanization moulding experts will begin their processes as soon as the temperature rises in order to speed up the moulding of custom silicone rubber keypads. Sometimes it does shorten the cure period, but other times it is counterproductive and causes a lot of numbness and rupture rather than enhancing productivity.

Natural rubber (NR) vulcanization temperature recommendations: the most suitable range is 140 to 150 °C, with a maximum temperature of 160 °C.

Butadiene rubber (BR), isoprene rubber (IR), and neoprene rubber (CR) should be vulcanized at temperatures between 150 and 160 °C, with the peak temperature not surpassing 170 °C.

The suggested vulcanization temperature for SBR and NBR is over 150°C, with the peak temperature not exceeding 190°C.

NextGen’s Oscillating / Automatic Disc Rheometer (ODR) temperature display resolution is 0.01°C.

By monitoring the applied moment of rubber to the oscillating dye body, this machine is intended to obtain the characteristic curve and characteristic parameters of rubber vulcanization. The results are quite stable when using the NG-ODR rotor-free vulcameter. The information and diagrams can be consulted for development, research, and product quality.

NG-ODR precisely and promptly describes the curing and processing characteristics of rubber compounds that have been vulcanised. It operates on a very basic idea. Under positive pressure and while being kept at a predetermined high temperature, a test piece of rubber compound is kept inside a sealed test cavity. A Rotor (oscillating disc) that is placed in the test component oscillates via a limited rotary amplitude that is determined. The test piece experiences a shear strain as a result of this motion. Depending on the stiffness (shear modulus) of the rubber compound a torque is required to oscillate the disc.

NextGen’s Oscillating / Automatic Disc Rheometer (ODR) is computer controlled.

Rubber undergoes physical modification during vulcanization as a result of being forced to retract. Of course, mechanical techniques can also make rubber retract using force. But vulcanization is different since the rubber's natural shape is preserved. Rubber shrinks during the vulcanization process while maintaining its original shape. The process of vulcanization essentially shrinks rubber without distorting or changing its shape.

Vulcanization not only modifies rubber's size while maintaining its shape but also guards against further deformation. Rubber hardens and becomes less prone to distortion as it contracts. Vulcanized rubber won't deform as easily as regular, non-vulcanized rubber, but it may still distort if subjected to significant stress.

When rubber is vulcanized, it also becomes harder, increasing its tensile strength and lowering the possibility of physical harm.

Depending on where it comes from, rubber can be divided into natural rubber and synthetic rubber.

Latex, a milky-white liquid produced by the rubber tree (Hevea Brasiliensis) or other plants, is the source of natural rubber.

Conversely, synthetic rubber is a man-made polymer made from petroleum waste. Rubber is now thermoplastic, squishy, and sticky and has low tensile strength and elasticity.

The qualities of both natural and synthetic rubber can be enhanced by vulcanization, turning them into a strong, hard, non-thermoplastic substance with increased tensile strength.

The vulcanization process involves three stages:

The crosslinking process begins at a temperature between 180 °F (82 °C) and 230 °F (110 °C) during the flow duration of the induction step.

Permanent crosslinks are created during the curing stage, which is ultimately influenced by the rubber's composition, activity level, reaction time, temperature, and curing stage conditions.

All of the qualities in the rubber compound are generated as the curing process progresses to the point where it reaches its elastic behaviour in the final stage, also known as the optimum condition of cure.

The rheometer measures the vulcanization strength required for the test specimen's deformation. The term "rheometer curve" refers to the strength's shift over time. These curves aid in assessing the rubber compound's quality.

These are the testing curves and results for NextGen’s Oscillating / Automatic Disc Rheometer (ODR):

  • ML - Minimum torque (dNm) - Measures value of the vulcanization characteristic (viscosity) of the unvulcanised test sample

An elastomer that has been strengthened by the biochemical process of vulcanization is known as vulcanized rubber. A curing agent, typically sulphur, is mixed with the milky latex from the rubber tree and heated under pressure.

Rubber and sulphur are chemically combined during vulcanization. The sulphur atoms join lengthy chains of rubber molecules when under high pressure and heat. This lessens the stickiness of the rubber while increasing its strength and durability. Additionally, it enables the rubber to maintain its flexibility across a much larger temperature range, making vulcanized rubber significantly more beneficial for a variety of applications.

Rubber becomes more durable, resilient, and heat resistant by vulcanization, making it more useful for industrial applications and some products. Vulcan, the Roman deity of fire and metalworking, is the source of the word "vulcanized."

Rubber and a functional group undergo vulcanization, a chemical process that is typically triggered by heat. As a result, the product is more durable, elastic, resilient, and resistant to solvent action and temperature fluctuations than the original polymer was.

Chemical vulcanization involves heating rubber at 140–160 °C with sulphur, an accelerator, and an activator. Longer rubber molecules are cross-linked during the process to improve elasticity, resilience, tensile strength, viscosity, hardness, and weather resistance.

Rubber is reduced in size by vulcanization without changing or deforming its shape. Additionally, it keeps its shape, guarding against further deformation of the rubber.

Using the most common vulcanizing agent to vulcanize the rubber Rubber that is not saturated begins to cross-link when sulphur is added. Sulphur, as a vulcanizing agent, does not, however, work quickly. Chemical reactions involving rubber and hydrocarbons frequently include double bonds or C==C, and each cross-linking requires 40–55 sulphur atoms without an accelerator.

Rubber that has been vulcanized is substantially stronger than regular rubber. Since it can handle more strain and stress, many manufacturing companies choose it.

Rubber that has been vulcanized is also more elastic than unvulcanized rubber. Many individuals believe that flexibility and strength are related. However, just because something is sturdy doesn't automatically rule out the possibility of it being elastic. Rubber that has been vulcanized is durable and stretchy. It may be stretched further without permanently deforming, thanks to its improved flexibility.

Traditional rubber is often less resistant to abrasion than vulcanized rubber. Damage from scraping is what is meant by abrasion. Rubber that has been vulcanized is stronger and harder than unvulcanized rubber, which makes abrasion damage less likely.

When the rubber reaches a temperature of between 300 and 400 degrees Fahrenheit, it is taken out of the heating chamber and left to cool.

The temperature range of NextGen’s Oscillating / Automatic Disc Rheometer (ODR) is Room Temperature to 22°C - 200°C.

Any sort of rubber that has been made harder by using heat and sulphur is vulcanized rubber. It is created by a curing process in which heat and sulphur cause the rubber's elastomers to harden. New cross-links are formed in the rubber as a result of exposure to heat and sulphur, making it stronger and more elastic overall.

A multi-step vulcanization method is used to create vulcanized rubber. The rubber is first immersed in a sulphur and additive-filled solution. Sulphur is the main component that promotes vulcanization. However, it is combined with additional chemicals. Both colour-enhancing pigments and a process accelerator may be included in the bath.

The rubber is then shaped in the manner desired. Moulding vulcanized rubber is difficult. Instead, because of its strength and flexibility, it is challenging to mould. As a result, the rubber is moulded after being immersed in a sulphur and additive bath.

NextGen’s Oscillating / Automatic Disc Rheometer (ODR) temperature accuracy is within ±0.3°C.

The curing and processing characteristics of vulcanized rubber compounds are precisely and promptly described by NG-ODR. It operates on a fairly straightforward idea. A test piece of rubber compound is kept at a predetermined elevated temperature and enclosed in a sealed test cavity under positive pressure. The test item contains an embedded Rotor (oscillating disc) that oscillates through a narrow range of rotary amplitudes. The test piece experiences a shear strain as a result of this action, and the torque (force) necessary to cause the disc to oscillate depends on the stiffness (shear modulus) of the rubber compound.

Rubber is created through a series of activities that entail the addition of value-adding material through chemical reactivity, irreversible physical feature modification, and flow. Extrusion, calendaring, vulcanization, and breaking down the polymer through mastication on a mill are the processes that are crucially important during chemical modification in tyre production.

This device is intended to measure the applied moment of rubber to the oscillating dye body in order to obtain the characteristic curve and characteristic parameters of rubber vulcanization. The results from the NG-ODR rotor-free vulcameter are highly stable. The information and illustrations can be used as a guide for development, investigation, and product quality.

Sulphur is necessary for the majority of vulcanizing techniques. Sulphur does not vulcanize synthetic polyolefins since it is a sluggish vulcanizing agent. Various substances that alter the kinetics of crosslinking are used to accelerate vulcanization; this mixture is frequently referred to as a cure package. Most street-legal car tyres are made of styrene-butadiene rubber (SBR), which is the primary polymer exposed to sulphur vulcanization. For the substrate and application, the cure package is customized.

A number of procedures are used for vulcanizing rubbers. The most popular method of treating natural rubber with sulphur was the only one to which the phrase originally applied. It has expanded to now include several methods for hardening other (synthetic) rubbers. Examples include the room-temperature vulcanization of silicone rubber and the use of metal oxides to vulcanize chloroprene rubber (neoprene).

The term "vulcanization" and "curing" are occasionally used synonymously in this context. Vulcanization is the process of curing elastomers. It functions by creating cross-links between polymer chain segments, increasing the material's rigidity and endurance, as well as altering its mechanical and electrical properties. Similar to the curing of other thermosetting polymers, vulcanization is typically irreversible.

Rubber hoses, shoe bottoms, toys, erasers, conveyor belts, vibration mounts/dampers, insulating materials, tyres, and bowling balls are just a few examples of the many applications for vulcanized materials. Most rubber products are vulcanized, which greatly increases their strength, durability, and longevity.

The recurrent or periodic change of a quantity around a central value (often an equilibrium point) or between two or more different states is known as oscillation. An alternating current and a swinging pendulum are two common examples of oscillation. In physics, oscillations can be used to simulate complex interactions like those between atoms.

The beating of the human heart (for circulation), business cycles in economics, predator-prey population cycles in ecology, geothermal geysers in geology, the vibration of strings in guitars and other string instruments, the periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy are just a few examples of dynamic systems that oscillate outside of mechanical systems.

When it comes to processing control and control theory (as in sliding mode control), where the goal is the convergence to a stable state, oscillation, especially rapid oscillation, may be an undesired feature. It is referred to as chattering or flapping in these situations, such as valve chatter and route flapping.

When a rubber compound is vulcanized, its properties change, and the vulcanization characteristics can be discovered by observing how the qualities vary with temperature and time. The tools known as curemeters are used to apply cyclic stress or strain to a test piece and measure the resulting strain or force in order to identify the features of vulcanization. The test is typically conducted at a predetermined constant temperature, with the stiffness measurement being continually recorded as a function of time.

The rubber becomes more rigid as the vulcanization process continues. When the observed stiffness reaches a plateau or a maximum and then starts to fall, vulcanization is complete. The loss of stiffness in the latter instance is brought on by reversion. When the observed stiffness keeps increasing (marching-modulus cure), vulcanization is regarded as complete after a certain time.

In the cure metre test cavity, a test sample of vulcanizable rubber compound is placed, and after a closure action, it is enclosed in a sealed cavity under positive pressure. The cavity is kept at a higher-than-normal vulcanization temperature. After the dies are closed, a biconical disc is completely encased in rubber. The test specimen experiences a shear strain as a result of the disc oscillating via a short rotating amplitude (1° or 3°). As a function of time, the force needed to rotate or oscillate the disc at its greatest amplitude is continually recorded, with force being proportional to the shear modulus (stiffness) of the test specimen at the test temperature.

The test is considered to be finished when the recorded torque reaches its equilibrium or maximum value or when the allotted amount of time has passed.

For Torque characteristics, the MI (Initial torque), ML (Minimum Torque) and MH (Maximum Torque) can be ready from the Cure Curve. Time values are indicated as ts2 (Induction time), ts5 (scorch time), tc50 (optimum cure time) and tc90 (optimum cure time). Finally, the derived values consist of the curing rate "CR", the Thermoplasticity (Tp=MI-ML) as well as the Reversion time "RT".

The Cure Curve is the measure of Torque Vs Cure Time and is a clear indication of all the rubbers vulcanization characteristics. The Cure Curve, or Rheograph, is separated into three phases. Phase 1 provides a good indication of the processing behavior of the compound. Phase 2 provides the technician with information on the curing characteristics. Phase 3 supplies information on the physical traits and properties of the rubber compound.

A test specimen of a rubber compound is contained in a sealed test cavity which is held under a positive pressure and maintained at a specified elevated temperature dictated within the ASTM or ISO standard. A rotor (biconical disc) is embedded in the test specimen and is oscillated through a specific rotary amplitude. The rotor exerts a shear strain on the specimen and the torque required to oscillate the rotor depends on the toughness of the compound.

The vulcanization of rubber is defined as the curing of elastomers – in other words, it is the analysis of the processes involved with the hardening of rubbers. Knowing the characteristics of the vulcanization process can help determine the rubbers rigidity and durability, as well as other mechanical and electrical properties of the material.

The Rheometer is used to evaluate test batches and ensure consistency. Since materials are mixed in batches, there can be variations which need to be controller and limited to ensure a consistent product being produced. By testing material from different batches, production environments can set acceptable upper and lower control limits, ranges, the mean and standard deviation with reference to Rheological parameters. With this information, future batches can then be tested and easily fit within set Pass/Fail criteria.

The Rheometer allows for the curing characteristics of the Rubber Compound to be evaluated while also monitoring the processing characteristics and the physical properties of the test specimen. The "Cure Curve" provided after the test is the diagnostic of the compounds vulcanization and processing character.

The testing results of the Oscillating Disk Rheometer can be used for quality control in rubber manufacturing plants, for research and development on raw rubber compounded in an evaluation formulation and for analyzing raw materials in the preparation of rubber compounds.
