Q Introduction of ISOBUTHANE Refrigerant Gas R600a

A

1. Introduction to R600a

R600a refrigerant: alias R600a, Chinese name isobutane, English name isobutane, trade name Reflube 600a

Application: refrigerant;

Chemical formula: C4H10;

Type: Hydrocarbon refrigerant;

2. Application of R600a

It is mainly used to replace R12 and R134a refrigerants in refrigerators, freezers, and other small refrigeration equipment; because R600a is flammable, it is usually only used in low-temperature refrigeration equipment with a small amount of liquid. It is also often used as a mixed refrigerant. Two components; R600a is compatible with traditional lubricants;

High-purity isobutane is mainly used as standard gas and the preparation of special standard mixed gas;

Used in the synthesis of isooctane, as a gasoline octane improver, used in the production of isobutylene, propylene, methacrylic acid, and used as a refrigerant.

Reusable steel bottle packaging (recycled packaging steel bottle): 60kg/118L, 200kg/400L, 400kg/800L,470kg/926L

6. R600a refrigerant storage and transportation

(1) R600a storage

R600a refrigerant cylinders are pressure vessels. They should be stored away from fire, heat sources, and direct sunlight. They are usually stored in a cool, dry and ventilated warehouse;

R600a is stored separately from oxidants, combustibles or combustibles, and aluminum. Remember to store them together.

The storage area should be equipped with leakage emergency treatment equipment

Pay attention to the product name and the date of acceptance during acceptance, and use advanced warehouses first;

(2) R600a transportation

You must wear the safety helmet on the cylinder when transporting the cylinder. Place the steel cylinders horizontally with the mouth of the cylinder facing the same direction. Do not store them crosswise;

Please load and unload lightly during transportation to prevent damage to accessories such as cylinders and valves.

In summer, it should be transported in the morning and evening to prevent sun exposure and away from heat sources;

It is forbidden to drop off during railway and road transportation;

Do not mix with oxidizers, combustibles or combustibles, active metals, etc.;
