Abstract
The utility model relates to a chinlon 6 continuous production pre-polymerization system which comprises a material-storage tank (1) and a pre-polymerization pipe (3), wherein the material-storage tank (1) and the pre-polymerization pipe (3) are arranged in series. The chinlon 6 continuous production pre-polymerization system is characterized in that a series pipeline of the material-storage tank (1) and the pre-polymerization pipe (3) is provided with a heater (2). By means of the chinlon 6 continuous production pre-polymerization system, material is pre-heated by the heater before entering the pre-polymerization pipe, consequently staying time of the material in the pre-polymerization pipe is shortened, and the phenomenon of overquick local heating can not happen. In addition, the chinlon 6 continuous production pre-polymerization system is fewer in side effects and good in stability of product quality.
Description
Technical field
The utility model relates to a kind of polyamide fibre 6 and produces continuously the pre-polymerization system, belongs to the chemical production equipment technical field.
Background technology
Polyamide 6 section is commonly called as chinlon 6 section, nylon 6 slice.Because containing amido linkage (one C-NH one) in the macromole, so be called polymeric amide.The chinlon 6 section cylindrical particle shape that usually is white in color, fusing point is 210-220 ℃, decomposition temperature is about 300 ℃.Dissolve in the vitriol oil of phenol and heat, electrical insulation capability is superior, alkaline-resisting, good corrosion resistance.Polyamide fibre is the best fiber of wear resisting property in the synthon.Because it has good wear resistance and corrosion resistance nature, becomes the main raw material of tire dipped type cord fabric, it is raw material that polyamide fibre 6 adopts the hexanolactam solid when producing, and makes by melting, batching, pre-polymerization, polymerization, casting section, extraction.
In the existing production technique, after batching is finished, directly be delivered to the pre-polymerization reactor by transferpump and carry out the pre-polymerization reaction, need in the reaction process to heat, owing to be direct heating in the pre-polymerization reactor, consumes energy is high, and long reaction time, in addition owing to cause easily local heating too fast and so that side reaction increases, affect the final performance of product.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of polyamide fibre 6 to produce continuously the pre-polymerization system, can shorten the pre-polymerization reaction times, and side reaction product is few, constant product quality is good.
The purpose of this utility model is achieved in that a kind of polyamide fibre 6 produces the pre-polymerization systems continuously, and it comprises material-storage jar and pre-polymerization pipe, and the setting of connecting with the pre-polymerization pipe of described material-storage jar is provided with well heater on the series pipe of described material-storage jar and pre-polymerization pipe.
Compared with prior art, the beneficial effects of the utility model are:
The utility model polyamide fibre 6 is produced the pre-polymerization system continuously, enter pre-polymerization Guan Qianxian at material and preheat by well heater, shortened the time that in the pre-polymerization pipe, stops, and can not produce the too fast phenomenon of local heating, side reaction is few, and constant product quality is good.
