In order to improve the corrosion resistance of ordinary steel sheets, people have invented galvanized steel sheets, and galvanized thin steel sheets are also commonly known as galvanized iron sheets and white iron sheets.
Due to its good sealing, preservation, light protection, firmness and unique charm of metal decoration, tinplate packaging has a wide range of coverage in the packaging container industry, and is a universal packaging variety in the world. With the continuous enrichment of various CC materials, DR materials and TFS, the development of packaging products and technology has been promoted. Tinplate packaging is full of innovation everywhere. Due to its strong oxidation resistance, diverse styles and exquisite printing, tinplate packaging containers are loved by our customers and widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrument packaging, industrial product packaging and so on.
Abstract: Because chemical containers also have certain chemical properties, they will inevitably be affected by chemicals during use, and their lifespan is limited. If they are damaged in the production process, it will bring serious consequences. Therefore, it must be Carry out periodic inspections, grasp the situation of chemical containers in a timely manner, and take effective measures to remove unsafe factors in the containers, eliminate potential safety hazards, and ensure the safe use of containers. This paper will start with the classification and characteristics of chemical containers, analyze the unsafe factors in the process of chemical container detection from different angles, and propose corresponding solutions.
Where is the core of quality improvement? Is it in technology, or is it in equipment? No, the core of quality improvement is to change people.
At present, the application in the Chinese market has gradually become more widespread, and many chemical barrel manufacturers have begun to choose to use film laminated galvanized steel sheets to produce chemical barrels and bottom&covers.
Recessions and contractions have always prompted shifts in consumer behaviour, with sensible suppliers having to cope with tight budgets by adjusting prices and product lines accordingly. Sometimes such periods bring unexpected shocks that permanently change the situation so that it will never be the same again.
Tin-plated thin steel plate is a kind of steel plate coated with a very thin layer of pure tin layer, referred to as tin plate, also known as tinplate. Tin plate has good corrosion resistance, good stamping molding performance and welding performance, with bright and beautiful appearance, is the best material for food packaging, in addition, it is also used in beverage, chemical, electronics and other industries.
The process size of drum flanging is determined according to the need of flanging. When the edge is rolled, the edge roller is used to seal the top and bottom cover of the barrel into a complete steel barrel, which is the process of the flanging flange of the bottom cover and the flanging flange of the barrel body. In order to achieve certain sealing performance and sufficient strength of steel drum coiling, the length of coiling, the amount of lap and the number of coiling layers are required. This is the basic basis for determining the flanging process size and the flanging width size of barrel top and bottom cover.

Basic specification requirements (1) There should be handles on the bucket (2) to use standard sealing system seals (3) Barrel body joints shall be connected by lap welding process (4) The bottom of the barrel top coil sealing, to inject sealant (5) Internal and external coating should meet the requirements of users (6) Mark according to UN standards
Cost is a part of the overall value, in essence is a kind of value sacrifice. If the enterprise is willing to sacrifice on the cost side, the sacrifice must be meaningful, value must be gained and perceived. Without a system that understands cost, value itself is sacrificed.
