Vulcanizing press introduction:

The rubber adapter vulcanizer is a device used for the vulcanization of rubber adapters.

1. Working principle

By applying high temperature and high pressure to the rubber adapter and maintaining it for a certain period of time, the rubber material undergoes a vulcanization reaction, thereby improving the strength, elasticity, wear resistance and other properties of the rubber. The vulcanizer is usually composed of a heating system, a pressure system, a control system, etc.

2. Main features

Precise control of temperature and pressure: ensure the stability and consistency of the vulcanization process and improve product quality.

High efficiency and energy saving: adopt advanced heating technology and energy-saving design to reduce energy consumption.

Easy operation: equipped with an intelligent control system, it is easy to operate and monitor the vulcanization process.

Strong applicability: It can be applied to the vulcanization of rubber adapters of different specifications and types.

3. Application field

It is widely used in the rubber products industry, such as the production of rubber adapters in the fields of automobiles, machinery, and chemicals. At the same time, it can also be used for the vulcanization of other rubber products.

II. Technical parameter

The vulcanization process of the rubber adapter vulcanizer is mainly divided into the following types:

Hot vulcanization:

Direct vulcanization: Place the rubber adapter directly in hot water or steam medium for vulcanization. The advantages of this method are high heat transfer efficiency and fast vulcanization speed, which can make the rubber products reach the vulcanization temperature quickly and have good vulcanization uniformity. For example, it is widely used in the production of some rubber adapters with high requirements for vulcanization speed and relatively small size. However, steam vulcanization may cause appearance problems such as watermarks on the surface of the product, so it should be used with caution for products with extremely high appearance requirements.

Indirect vulcanization: Place the rubber adapter in hot air for vulcanization. Hot air vulcanization can be carried out under normal pressure or pressure. The advantages are that the heating temperature is not affected by pressure, it does not contain moisture, it is relatively dry, and the appearance quality of the vulcanized product is better. However, the heat transfer efficiency of hot air is relatively low, resulting in a long vulcanization time, and it is easy to cause rubber products to oxidize during the vulcanization process, so it is usually suitable for products with strict requirements on appearance and low requirements on vulcanization speed, such as some special rubber seals, rubber shoes, etc.
Mixed air vulcanization: First use air vulcanization, and then switch to direct steam vulcanization. This method combines the advantages of air vulcanization and steam vulcanization, which can not only overcome the shortcomings of steam vulcanization affecting the appearance of the product, but also overcome the shortcomings of slow heat transfer, long vulcanization time and easy aging due to hot air.
Cold vulcanization: Use carbon disulfide solution containing sulfur chloride to impregnate the rubber adapter, and then wash and dry to complete the vulcanization. This method has a low vulcanization temperature and is usually suitable for temperature-sensitive rubber products such as film products.
Room temperature vulcanization: The vulcanization process is carried out at room temperature and normal pressure, and room temperature vulcanization slurry (mixed rubber solution) is generally used for vulcanization. For example, this method is used in bicycle inner tube joints, repairs and other scenes. It is easy to operate and does not require special equipment and high temperature conditions.
Microwave vulcanization: Use microwave energy to heat and vulcanize the rubber adapter. Microwaves usually refer to electromagnetic waves with a frequency between 300~30000MHz, which can rapidly increase the temperature of the rubber compound. It has the advantages of fast heating speed, short vulcanization time, good vulcanization uniformity and energy saving. Moreover, for some rubber adapters with complex shapes and large thicknesses, microwave vulcanization can quickly heat up the inside and outside at the same time, overcoming the vulcanization quality problem caused by uneven heat transfer in traditional vulcanization methods.
High-frequency vulcanization: The rubber adapter is vulcanized by heat generated by a high-frequency electric field. This method has the advantages of high frequency, small footprint, and clean products. It is suitable for products of various sizes and complex cross-sectional configurations, and can be used for continuous vulcanization of tapes, hoses, and wires.
Nitrogen vulcanization: Vulcanization is carried out by filling with nitrogen. The main advantages are energy saving and extending the service life of rubber products such as capsules. Nitrogen has a small molecular weight and a small heat capacity. When it is filled into the interior of a rubber product, it will not absorb heat and cause the temperature to drop, nor will it easily cause oxidation and cracking damage to the product. However, nitrogen vulcanization has high requirements for equipment and nitrogen purity, and requires a special nitrogen supply system and purity detection equipment.
