Development Trend of Steel Barrel Raw Material

First, the steel drums making machine dedicated raw steel development

Special packaging materials steel drums development will become a reality , not only more suitable drums product quality requirements for raw materials , but also the use of material savings , the economy is also more prominent.

Currently used drums drums raw materials for production , in addition to the domestic hot-rolled plate drums , other materials are not for the production of special steel drums , so the quality is uneven . Some uneven material thickness , carbon content is too high , the hardness is too large , resulting in steel drums difficult to guarantee quality ; substandard size drums and some materials production requirements , scrap too much material waste ; some galvanized sheet zinc layer thickness is not enough , so that greatly reduced the ability anticorrosive steel drums ...... like the problem is really endless.

In Europe and the United States and other more developed countries , suppliers of raw materials for the steel drums enterprises tailored to meet the requirements of not only the quality , but also to have some economic ; material size as needed ruled scrap almost zero. Currently in some of China's foreign investment or joint cooperage business, they supply or cut the top end of the barrel material is the hypotenuse , the steel utilization increased by a quarter , if a small cooperage plant producing 200,000 a year drums , you can save material funds 50-60 million. As a result , the quality of the drums , to achieve the best cost . Therefore, in our country, the emergence of special materials, steel drums imperative.

Second, the development of steel drums sealant

Drums sealant development will be on a higher level , and should comply with these standards , mixed fish heads to change the current situation.

Drums seaming seal packing , commonly known as sealants, when the top and bottom steel drum barrel body seaming , the fill cracks in the seal crimping . Because steel drum roll to win the title , curling site has a certain rigidity rebound , rebound to make the original volume appeared tight curling gap . So, with the seal crimping gap fillers , can effectively improve the ability of anti-leakage steel drums . Over the years our drums sealant mostly made ​​of natural white latex , but some manufacturers use a variety of other types of fillers .The absence of uniform standards and quality requirements, so manufacturers have come out of nowhere , the feel of development and production . Steel drum manufacturing companies do not know good or bad, in use, to explore, often resulting quality of the accident . Currently more prominent contradictions , this situation may not last long. Steel drum manufacturing process on the sealing filler have the following requirements:

① compatibility.

② high temperature stability .

③ high solid component content .

④ good adhesive properties.

⑤ better flexibility .

⑥ better workability .

⑦ certain weatherability.

Is now more difficult to solve the compatibility problem , such as the contents of sealant from a chemical reaction , while pollution of the goods , on the other hand the sealing performance.

In other countries, a number of types of sealants drums , drums of different purposes are not the same sealant used , but also high-quality , high-efficiency construction . In the future , China's steel drums with sealant into the design and production will be gradually standardized, the only way the quality of steel drums will be a strong guarantee.

Third, the new green paint application and development

New green paint application and development of a comprehensive go their green drums important step .

In recent years , the domestic paint production quality and yield have a very substantial increase , their types and varieties increased significantly, highlighting the enhanced performance , attention to environmental protection. Many varieties of pollution -based coatings have been developed , so that our coating structure has undergone great changes. However, in the field of painting drums , green new paint application is in its infancy , has not been attention and application .

At home and abroad rapid development of new environmentally friendly paint are:

① pre-coated paint . Pre-paint coating is a coating of a major change , it is the finished product from the final coating material for coating steering , thereby reducing contamination of the coating process . Currently precoated steel sheet and color developed rapidly in the world ;

② waterborne coatings : These new paint is acrylic liquid and carbon black , additives and other blend . Its characteristics are water as dispersion , without any organic solvents, consistent with national environmental regulations, are environmentally friendly.

③ adhesive coating: This is a kind of a color coating and adhesive coated polymer film . It has good durability , weather resistance , can be easily attached to the surface of the product . Since it replaces the solvent-based paints , so for environmental protection is concerned, it is of a transformational new paint ;

④ powder coating : Powder coating is the powder coating solvent , the solvent is eliminated unwanted scattering of the powder overspray can be recovered for reuse .Painting is not only good quality , high efficiency, more importantly, reduce and eliminate pollution of the environment , improved working conditions , energy conservation, is the new trend in the development of steel drums painting .

⑤ benzene coatings : paint and solvents not benzene content , thereby reducing the environmental pollution . This is the low-pollution paint has been applied .

Fourth, the drums will be dedicated with the direction of tinplate

Steel drum with tin will be dedicated development direction, scope of application will be more clear and specific .

Currently , a large number of international manufacturers for the production of tinplate packaging containers , which made a special needs . In special packaging development and production of tinplate , the European walking in the forefront of the world . In recent years , the French steel company first developed a packaging tin , and put into the market , causing a revolution in the packaging industry .

Now , our purpose is not to use most of the distinction between tinplate manufacturing steel drums and other containers often unstable quality problems . If they can use a dedicated tin , since the material affect the quality of the problem is solved . In fact, the domestic packaging containers of product quality issues , the problem of scrap and materials largely related . Exclusive use of tin in Europe illustrates this point .

Tinplate packaging development direction are:

① reduce the material thickness ;

② to improve the mechanical properties of materials ;

③ achieve a variety of needs tin layer thickness.

Therefore special tin reduces cost of the product , to ensure high quality of the products , different changes in the product tin coating adaptability, the economy tends to be more improved.

Five , drums manufacturing equipment and gradually increase the degree of automation

Steel drum manufacturing equipment gradually increase the degree of automation , technology will become more sophisticated and simplistic.

Since the introduction of foreign advanced equipment and technology , China's steel drum technology have larger development. At present, he is gradually digest and absorb these technologies , new equipment are constantly being developed. In the future, there will be a leap of steel equipment development , to achieve full automation, technologies and processes will also be more mature, will gradually eliminate backward technology and sophisticated technology, using international advanced equipment and technology to arm themselves , forming and other industries compatible development .

At present, China produced more steel equipment manufacturers , has gradually formed an industry , they continue to carry out research equipment replacement at any time there is a new device to the fore, which is unprecedented development . In the future, cooperage equipment replacement will be faster and catch up with the world advanced level just around the corner .
