What are the basic knowledge of vulcanization tanks and what to pay attention to when choosing to bu

Vulcanization tank is the earliest vulcanization equipment used in the production of rubber products, over the years, although other vulcanization equipment has developed greatly, but until today the vulcanization of some rubber products (hoses, rubber shoes, rubber rollers) is inseparable from it, that is, molded products, tape products, boxes, cable products also have the application of vulcanization tank vulcanization, it can be seen that the vulcanization tank is still one of the basic equipment for vulcanization.

Uses and classifications.

1. Use and classification.

1. Uses: The horizontal vulcanization tank is mainly used for vulcanizing flying model rubber products, such as rubber shoes, rubber hoses, cables, rubber roller boxes, adhesive tape, etc., and sometimes, it is also used for vulcanizing model rubber products.

2 Classification. 1) According to vulcanized rubber products.

Rubber shoe vulcanization tanks, hose vulcanization tanks, adhesive tape and rubber roller vulcanization tanks.

Its structure is basically the same, but in order to prevent the rubber from being heated and softened and casted during the vulcanization process, the vulcanization tank for vulcanized tape and rubber roller is specially equipped with a rubber tape roll or rubber roller rotation transmission device. In addition, the vulcanization tank for hose vulcanization generally uses direct steam heating vulcanization, and there is no hot air circulation device in the tank. ）

2) According to the structural form of the vulcanized tank.

Direct heating of the vulcanization tank.

Indirect heating of vulcanization tanks.

The direct heating vulcanization tank body is directly connected to steam heating vulcanization, and the indirect heating vulcanization tank is mostly heated by steam heat dissipation pipe installed in the tank to heat vulcanization. In the past, indirect heating vulcanization tanks used a jacket structure, in which steam was introduced into the jacket to heat the vulcanization. But this structure is troublesome and is now largely unnecessary.

In addition, in order to obtain a higher vulcanization temperature, a vulcanization tank with electric heating has been developed in recent years).

Second, the basic structure.

The working pressure of the horizontal vulcanization tank is generally below, which belongs to a low-pressure type of container, most of which are single-walled cylindrical structure, which is composed of the tank body, the tank cover and its switch and locking device, heating device and other auxiliary devices.

3. Specification representation and technical parameters.

1 Specification representation.

The horizontal vulcanization tank adopts the unit M of "tank body diameter effective length", and the model is represented by XL, and the letter J is added after XL for the horizontal vulcanization tank for vulcanized products and rubber shoes. Therefore, the model of the vulcanization tank is expressed as follows: such as 11, 3, etc.

2 Technical Parameters.

Tank diameter, heating method, working medium, working pressure, working temperature, dimensions, etc.

Fourth, use caution.

The vulcanization tank is a pressure vessel, and it is necessary to pay attention to the prevention of accidents in production.

Operators should strictly abide by the process flow and labor discipline, and operate in strict accordance with the safety technical operation procedures. Enterprise managers should understand the basic knowledge of pressure vessels and laws and regulations, and vulcanization tank operators should be professionally trained and certified.

For more information, please refer to the "Encyclopedia".

Time, temperature and force are the three elements of the vulcanization tank.

<>1. When the vulcanization tank arrives at the use site, it is necessary to hold a full set of certificate procedures issued by the manufacturer. valves and pressure gauges are filed with the local quality supervision bureau for valve instrument calibration.

2. During the working process of the sulfur service tank, the staff should observe the temperature and pressure data in time, and there can be no ultra-high temperature hand envy and ultra-high pressure, and evacuate the scene immediately once the situation is found.

The vulcanization tank is a kind of rubber vulcanizing tank equipment that has a long history and has been in use. For enterprises using this equipment, purchasing high-quality and low-cost products can not only improve the production power, but also reduce the cost of production, and achieve twice the result with half the effort.

1. Understand the popularity of vulcanization tank manufacturers: many users will feel that it is best to buy from large or old qualified manufacturers.

2. See whether the main material and equipment accessories selected for the vulcanization tank are well-known brands, whether the main materials and accessories meet the planning requirements for the pressure vessel have a very important relationship with the quality of the product, because the best of the vulcanization tank equipment is not low, so we must pay more attention to each component of the machine when purchasing, and at the same time, the customer should also have some understanding of the equipment.

3. Check whether the functions of the vulcanization tank are complete and can reach the advanced level, and you can not choose a machine with backward technology, for example, even if you don't want to use a fully automatic vulcanization tank, you can also ask whether it can be equipped with a fully automatic control system to judge the technical strength of the manufacturer, and pay more attention to the safety interlocking device of the vulcanization tank.

4. After-sales service is very important: the general vulcanization tank manufacturers can assist in the preparation and planning, the layout of the supply site, and the selection of supporting equipment before the sale. Equipment commissioning, operation training, production process guidance and other work.

5. Absolutely can not buy equipment without a license and fake manufacturers: the equipment of these manufacturers is likely to be safe and unguaranteed, professional manufacturers have relevant pressure vessel manufacturing certificates, if you can't get the certificate, even if the customer buys such a product, the safety is not guaranteed, if the pressure vessel is unqualified, there will be a first-class danger, the loss is difficult to estimate, and the equipment of these manufacturers does not have the pre-factory pressure test of the phase department, resulting in your equipment can not be inspected in your local area, can only be secretly produced.

Storage of sulfuric acid. The sulfuric acid tank is a tank for storing sulfuric acid in the chemical industry, and the sulfuric acid tank for storing sulfuric acid in the domestic market or enterprises is made of carbon steel. Concentrated sulfuric acid has strong oxidizing properties, and will passivate with aluminum, iron and other metals, so that the metal surface forms a dense passivation film (metal oxide film), which plays the role of isolating reactants, protects the pure metal elements in the film, and no longer reacts with the strong oxidizing acid outside the film, so the place where the iron tank of concentrated sulfuric acid is stored in contact with the concentrated sulfuric acid will form a dense oxide film and will not be corroded.

Carbon steel sulfuric acid tank has strict requirements for the welding process, such as the sand hole in the welding part will cause serious corrosion problems, and it is difficult to effectively solve the problem once leakage repair welding. Concentrated sulfuric acid has water absorption, and the moisture in the air will also dilute the concentrated sulfuric acid, which will increase the corrosiveness of carbon steel, which will seriously affect the normal use and service life of the equipment.

Vulcanization tank is the earliest vulcanization equipment used in the production of rubber products, over the years, although other vulcanization equipment has developed greatly, but until today the vulcanization of some rubber products (hoses, rubber shoes, rubber rollers) is inseparable from it, that is, molded products, tape products, boxes, cable products also have the application of vulcanization tank vulcanization, it can be seen that the vulcanization tank is still one of the basic equipment for vulcanization.
