Non-fiber Polyester Plant Soft Measurement Technology And Control Management Software Development And Application Of Research

With the non-fibe rpolyeste rapplying more and more wide in many fields, PET synthesized by the raw materials of PTA with EG has excellent mechanical property, insulativity ,wearable capability and barrier property. Since 1980's, our country has introduced into large reaction equipments and techniques of the different patent from abroad, but because of the control of the "knowhow" the work of the nationalization has be very difficult.This paper builtup esterification model, pre-polycondensation model, polycondensationmodel, and successfully built up monitoringon-line system of some key quality tar gets as well as operation systemmodel according to the polycondensation technique of NOY company. This model makes some keyquality tar gets such as IV ,DEG ,COOH etc control accuracy no more than2.5%, so the model is help to imitate and guide the actual production, and also provide some theory basis for some important equipments nationalizing.
