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.

Precautions when discharging oral liquid filling machine
Because the machine is an easy-pull bottle filling device, the discharge is sealed and sealed. To make the bottle after the filling is not turned over, be sure to put some empty bottles on the hopper before the first bottle is discharged. The bottle after the lock is kept smoothly conveyed to the discharge hopper, and sent to the next process with the bottle.
5. This lock device is designed to digest foreign advanced technology. According to the domestic oral liquid production situation, it is specially designed for easy-pull bottles. Therefore, there are certain requirements for the geometric size and error of easy-open bottles. If there are special requirements or other specifications, please With the technical department of the plant.
6, the adjustment of the lock device
a. Gland time adjustment: Adjusting the rotation angle of the cam 3 When the infusion bottle enters the tooth position of the lock port, the lock shaft has moved and leaves the bottle cap before the moving tooth approaches the bottle.
b. Adjustment of gland pressure: The pressure of gland pressure is directly related to the quality of the lock. The pressure is too large to break the easy-open bottle. If the pressure is too small, the sealing performance will be affected. Therefore, it should be adjusted according to the actual average height of the easy-pull bottle. Nut 6, so that the pressure is adjusted to Zui.
c. Blade movement time adjustment: the blade 2 should be close to the bottle neck before the gland is terminated. Otherwise, some short bottles can not achieve the locking effect. When adjusting, the nut 4 is loosened, and the adjustment shaft 5 and the upper and lower sides can make the blade 2 operate sooner or later. Note that the spring force of the adjustment spring 7 should be greater than the spring force of the spring 8 to keep the bottle neck still consistent.
d. When adjusting the lock, be careful: after adjusting the various departments, you must pay attention to the lock of each nut. When the initial valve is tested, use the easy-pull bottle. The average height must be taken. Irregular easy-pull bottles cannot enter the lock to avoid damage to the parts.
7, the adjustment of the vibrator
The automatic falling cover adopts the principle of electromagnetic oscillation to drop the bottle cap to a proper position along the track according to a certain movement track.
a. The vibrator is separately packaged at the factory. When installing, the lower rail opening must be aligned with the easy-open bottle movement track.
b. Adjustment of the magnet gap: loosen the screw 1, open the cover, adjust the nut 2, make the magnet gap 0.6-0.8, and make the vibration sound zui low cap line speed zui fast.
