Adipic Acid is mainly used in producing nylon fiber and engineering plastics, and polyurethane in quantity. Most of parts are used to produce PU, liquid for sole, polyurethane foam, etc. A small number of them are used for high quality lubricating oil.
High quality ester of adipic acid can be used as PVC and its copolymer, plasticizer of natural synthetic rubber. A large number of adipic acid ester is used to produce food packaging, thin film and PVC for insulation.
Adipic acid is also used for sour agent of food and drink. It is not easy to deliquesce, so it is used in dry food, and can be kept in a long time.

2. It is forbidden to store articles that are corrosive to steel around the concrete position of the spiral steel pipe;
3, the end of the spiral steel pipe should be elevated, firm, flat, to prevent moisture or deformation of the material;
4. The same kind of materials are stacked separately according to the order of storage;
5. Spiral steel pipe steel stacked in the open air must have a wooden mat or stone below, with a slightly inclined surface to facilitate drainage, and pay attention to the placement of the material in a straight line to prevent bending deformation;
6, spiral steel pipe stacking height, artificial homework does not exceed 1.2m, mechanical work does not exceed 1.5m, width not exceeding 2.5m;
7. There should be a certain channel between the stern and the sampan. The inspection road is generally 0.5m. The access channel depends on the size of the material and the transport machinery, generally 1.5 to 2.0m;
8, open stacking angle steel and channel steel should be laid down, that is, mouth down, I-beam should stand upright, steel I can not face up, so as to avoid rust;
9. The bottom of the raft shall be raised. If the warehouse is a sunny concrete floor, the elevation can be 0.1m; if it is mud, it must be 0.2-0.5m. If it is an open space, the cement floor height is 0.3-0.5m, and the sand-mud surface is 0.5-0.7m high.

Spiral pipe placement requirements
1. The principle of spiral steel pipe stacking is that under the premise of stable stacking and ensuring safety, it should be done according to the type and size of the pallets. Different types of materials should be palletized separately to prevent ramming and mutual erosion.
