Description

Nylon 66 salt water solution storage device

Technical Field

The utility model relates to a nylon 66 salt technical field specifically is a nylon 66 salt aqueous solution storage device.

Background

The nylon 66 salt is a monomer for synthesizing the nylon chain cloth, and is white or yellowish gem-shaped monoclinic crystal system crystals which are odorless, non-corrosive and slightly ammoniacal at normal temperature. Nylon 66 salt is relatively stable in dry or solution at room temperature, but when the temperature is above 200 ℃, polymerization occurs. At present, nylon 66 salt mainly comprises two production processes of an aqueous solution method and a solvent crystallization method. The aqueous solution method is to take water as a solvent, and the water solution of nylon 66 is obtained by neutralization reaction of equivalent weight of hexamethylene diamine and adipic acid in the aqueous solution. The method has the characteristics of no use of methanol or ethanol as a solvent, convenience, easiness, safety, reliability, short process flow and low cost. But the quality requirement on the raw material intermediate is higher, and the long-distance transportation cost is also higher. The solvent crystallization method is to prepare the solid nylon 66 salt by taking methanol or ethanol as a solvent and carrying out neutralization, crystallization, centrifugal separation and washing. Wherein, the purity of raw materials, crystallization temperature, mechanical loss, solvent concentration, dosage and the like have great influence on the yield and quality of the nylon 66 salt. In addition, impurities such as 1, 2-diaminocyclohexane, 1-aminomethylcyclopentane, aminocapronitrile, etc., remaining in the hexamethylenediamine, may affect the stability of the nylon 66 salt. The method has the characteristics of convenient and flexible transportation, good product quality, strong sensitivity to temperature, humidity, light and oxygen, and the need of adding water again for dissolution in the polycondensation operation. Most of the existing nylon 66 saline solution storage devices are too simple, manual observation and debugging are needed for the solution, and the solution is difficult to be kept in an ideal state; during manual adjustment of the solution, the solution in the tank is exposed to air, so that the solution reacts with the air.
