What are the environmental requirements for tire rubber production workshops?

The tire rubber production workshop has very strict environmental requirements, mainly reflected in the following aspects:

1、 Lighting and temperature control

Lighting: The storage of various components in tire production should strictly control the exposure of ultraviolet rays in sunlight, as ultraviolet rays can cause rubber aging and affect rubber adhesion. Therefore, production plants generally do not use sunlight for lighting. Even if there are windows on the walls, a layer of yellow paint should be applied to the glass to filter ultraviolet rays. Indoor lighting often uses a specially designed fluorescent tube that minimizes ultraviolet rays. In addition, some tire manufacturers use a light guide tube lighting system, which incorporates anti ultraviolet factors to block ultraviolet rays, making it the preferred lighting option for rubber, tire, and other production workshops that require UV isolation.

Temperature: The room temperature of the tire production plant must be kept constant, especially in the rolling production area, cutting production area, and molding production area, which must be strictly controlled and generally maintained at 22 ± 2 ℃. When the temperature is low, various components become hard, affecting adhesion, causing high component shrinkage, and making it difficult to control component dimensions; High temperatures make it difficult to operate various component processes. So the vast majority of factories use large-area air conditioning in the spindle room and molding area to maintain constant temperature and humidity.

2、 Humidity control

In China's tire industry, production workshops have very high requirements for air humidity. Generally, the air humidity in tire factory workshops should be controlled below 50%. Nowadays, new tires in the tire industry contain steel wires, and if the air humidity is too high during production, it will affect the quality of the products. In addition, water-soluble substances and components such as water droplets in rubber can be extracted, dissolved, hydrolyzed, or absorbed by water, especially under the alternating effects of water immersion and atmospheric exposure, which can accelerate the damage of rubber. For this reason, the humidity in the storage warehouse also needs to be controlled during the storage of tires. Industrial dehumidifiers can be used to control the temperature and humidity of production workshops and storage environments within specified ranges.

3、 Dust prevention measures

Dust has a isolating effect on rubber and affects its adhesion, so most tire production plants adopt closed management and take a series of dust prevention measures, such as:

The ventilation inside the factory is filtered.

The transportation of rubber and raw materials adopts an internal and external connection method where external vehicles do not enter the workshop and internal vehicles do not leave the workshop.

Some tire production factories require workers entering and leaving the workshop to change shoes, etc., to prevent dust from entering the production area.

4、 Safety and fire prevention

The biggest safety hazard in rubber, tire and other types of factory workshops is fire, which can be easily caused by electrical and environmental temperature factors. Therefore, the workshop should be equipped with fire extinguishers, fire hydrants and other fire-fighting facilities, and regularly inspected and maintained to ensure safe evacuation and firefighting in emergency situations. At the same time, some tire manufacturers adopt non electric lighting schemes such as light guide tube lighting systems to reduce the risk of fire. Because the system does not require electrical equipment and transmission lines, it effectively reduces safety hazards such as fires caused by high loads, aging of lines, short circuits, etc.

5、 Energy conservation and emission reduction

Most tire production workshops use roof daylighting strips, which have a large area and are prone to water leakage and dust accumulation at the junction of the daylighting strip and the roof. In addition, traditional electrical lighting is accompanied by 24-hour uninterrupted production, resulting in huge energy consumption. The maintenance and replacement of lighting fixtures are significant expenses. Therefore, tire production workshops should take energy-saving and emission reduction measures, such as using efficient lighting equipment (such as light guide tube daylight lighting systems), rational utilization of waste heat, etc., to reduce energy consumption and minimize environmental impact.

In summary, the environmental requirements of tire rubber production workshops involve multiple aspects, all of which are aimed at ensuring the smooth progress of the production process and stable and reliable product quality.
