Several Chemical And Physical Test Methods To Study Chemical Fiber Production Process

The development of the scientific research and production in petroleum chemical industry puts forward a new requirement to relevant modern analyses technology, and a lot of new analyses methods should be study and develop to increase the control accuracy , improve process conditions , heighten production quality and promote competition power in petroleum chemical industry.This thesis presents an applied study of several chemical and physical test methods to quantitative control based on the chemical and fiber produce process of Yingshan Petroleum Factory. The creative works are summarized five aspects as follows:1. The gas chromatography new method of ester and peroxide in cyclohexane oxide was established first time by derivation of peroxide and elimination of ester. The method is simple, rapid, sensitive and reproduction;2. The new solvent was found first time, it's cheap, easy-obtained, nontoxic and accuracy which can meet the control of production. Based on the compare experiment between homemade solvent such as carbinol, ethanol, normal pentane and 6# solvent oil and import solvent, we select the 6# solvent oil to substitute the import solvent;3. The relationship between predict fiber number and equilibrium fiber number was found first time. It help to establish the rational control criterion for predict fiber number according to equilibrium fiber number and achieve planed production by effectively production control, so this relationship has a wide applied field and great value in fiber industry;4. The factors of regulations that affect the measurement of breaking strength, elongation degree, strength extension have been grasped. It enables the improvement in method to measure breaking strength and elongation ratio of polyamide fibre.5. The failure of GB9102-1998 is found and the improved method isresearched. Based on the demand analysis of manufacture enterprise , downriver industry and market ,some improve methods and propose were presented as gist to modify the standard.
