Therefore, to prevent degradation and crystallization of nylon 66 salt, hot water at 45 ℃ is usually passed through a jacket with heat tracing and 99.99% nitrogen as a protective gas. In a two-stage nylon 66 salt reactor, the adipic acid slurry and the hexamethylenediamine solution are mixed and neutralized to form the nylon 66 salt. The reaction was carried out by withdrawing the circulating nylon 66 salt solution from the first salt-forming reactor (E-R110A) through the salt-forming reactor circulating pump (E-P115A/B), and by taking it away from the salt-forming reactor cooler (E-E115), the reaction temperature was kept at 49.5 ℃ by controlling the cooling water entering the reaction cooler.
The pH of the nylon 66 salt solution was controlled by controlling the flow of the adipamide, and a pH meter was installed on the recirculation line. The nylon 66 salt solution was almost completely neutralized in the first salt forming reactor (E-R110A) and the solution overflowed to the second salt forming reactor (E-R110B). The sugar particle size of the nylon 66 salt solution is adjusted by controlling the flow of pure water through a densimeter arranged on a circulating pipeline of the first salt forming reactor; and the detection of sugar granularity is through refractometer detection, because long-time use, some small greasy dirt, iron fillings can the adhesion on the prism of refractometer, thereby influence the measurement accuracy, in the prior art, all be through increasing one section measuring cell pipeline that can the dismouting, through fixed refractometer on measuring cell pipeline, thereby after working a period, thereby can conveniently wash or maintain measuring cell pipeline dismouting fifty percent discount light appearance, but above-mentioned setting can realize making things convenient for the washing and the maintenance of prism, but in the in-service use, still need the shut down of whole equipment during the washing maintenance, and the dismouting process is wasted time and energy.
