The renovation of calcium carbide packaging materials

The research, development, promotion and application projects of calcium carbide transport flexible bags completed by the Operations Department of the Qinghai-Tibet Railway Company and the use of new theories, new technologies, and new concepts in the packaging field boldly abandon the use of iron-based calcium carbide packaging that lasted for more than a hundred years and passed investigations. , Research, analysis, design, testing, improvement, and improvement. Based on the active use of various new materials that have emerged in the packaging field in recent years, new calcium carbide packaging has been developed. This research and its achievements are at the leading level in China.

Due to the rational design of the structure and the clever combination of its strength, sealing, and exhaust functions, the "carbide transport flexible packaging bag" is very suitable for the physical and chemical properties of calcium carbide in the packaging, storage and transportation process, thus ensuring the storage and transportation of calcium carbide in Security. The use of "carbide transport flexible packaging bags" to ship calcium carbide, which reduces the labor intensity in the loading and unloading process, reduces the cost to more than 55%, and fully utilizes the means of transport to reduce freight by more than 11%. Only the reduction of packaging costs, transport costs, and no need to return 3 items can reduce the cost by RMB 170/ton for the use of new packages for the shipment of calcium carbide. In addition, the use of â€œcarbide transport flexible bagsâ€ to ship calcium carbide, due to its moisture-absorbing and sealing functions, compared with the iron barrels, the loss rate of calcium carbide powder reduction from 15% to 3% compared to the iron barrels (when established The goal is reduced to 4%), which greatly reduces waste of resources and environmental pollution.

Since the project was promoted and applied in our province in 2000, due to the reduction of costs and the assurance of transportation safety, it has greatly promoted the development of the calcium carbide industry and related industries in our province, and has produced significant economic and social benefits.

A bookcase, or bookshelf, is a piece of furniture with horizontal shelves, often in a cabinet, used to store books or other printed materials. Bookcases are used in private homes, public and university libraries, offices and bookstores. Bookcases range from small, low models the height of a table to high models reaching up to ceiling height. Shelves may be fixed or adjustable to different positions in the case. In rooms entirely devoted to the storage of books, such as libraries, they may be permanently fixed to the walls and/or floor.

A bookcase may be fitted with glass doors that can be closed to protect the books from dust or moisture. Bookcase doors are almost always glazed with glass, so as to allow the spines of the books to be read. Especially valuable rare books may be kept in locked cases with wooden or glazed doors. A small bookshelf may also stand on some other piece of furniture such as a desk or chest. Larger books are more likely to be kept in horizontal piles and very large books flat on wide shelves or on coffee tables.
