1. Equipment Overview

• The flame treatment machine for paint buckets, plastic buckets, and lubricating oil barrels is a device used to improve the surface performance of these barrel containers. It treats the surface of the barrel through the high temperature of the flame, changing the surface state, so as to better meet the requirements of subsequent processing technologies such as printing and coating.

2. Working Principle

• The equipment uses the high-temperature flame generated by the combustion of combustible gases (such as propane, butane, etc.) mixed with oxygen to directly act on the surface of paint buckets, plastic buckets, or lubricating oil barrels. The high temperature of the flame will change the molecular structure of the barrel surface. For plastic barrels, it can remove impurities such as oil stains and release agents on the surface, and at the same time moderately oxidize the plastic surface to increase the surface energy; for metal paint buckets and lubricating oil barrels, it can remove rust and oxide layers on the surface, and activate the surface to improve its adhesion to subsequent coatings or inks.

3. Application Advantages

• Enhanced Adhesion: After flame treatment, the roughness and surface energy of the barrel surface can be improved. Whether it is printing patterns, sticking labels or applying protective paint, the corresponding materials can be better attached to the barrel surface, reducing quality problems such as peeling and shedding, and ensuring the durability of subsequent processing effects.

• Improved Cleanliness: Effectively remove dirt, dust and some chemical residues on the barrel surface, making the appearance of the barrel cleaner and tidier, which is conducive to improving the overall image of the product, especially for packaging barrels with appearance display requirements.

• Wide range of applications: It can be used for barrels of various materials, such as paint barrels, plastic barrels, and lubricating oil barrels made of common plastics (such as PP, PE, etc.) and metals (such as tinplate, galvanized sheet, etc.), which can be treated to meet the needs of different industries for barrel surface treatment.

4. Key points and precautions for operation

• Flame adjustment: According to factors such as the material, thickness and treatment purpose of the barrel, the size, temperature and action time of the flame should be reasonably adjusted. For example, thicker plastic barrels may require a slightly longer flame action time and a slightly higher temperature to ensure the treatment effect, while thin metal barrels should avoid deformation of the barrel body due to excessive temperature.

• Safety protection: Due to the combustion of combustible gases, the equipment must be equipped with complete safety protection devices, such as flame monitors, gas leak alarms, emergency shut-off valves, etc., to prevent safety accidents such as fire and explosion. Operators must also strictly abide by the operating procedures and wear corresponding protective equipment.

5. Application value of equipment in related industries

• Packaging industry: When paint barrels and lubricating oil barrels are used as product packaging, the surface after flame treatment can better print product logos, brand information, etc., improve the beauty and professionalism of the packaging, and facilitate the market promotion and sales of products.

• Chemical industry: For plastic barrels containing various chemical products, flame treatment can ensure the quality of the inner and outer coatings of the barrels, extend the service life of the barrels, and ensure the stability of chemical products during storage and transportation.
