efficiency decline Occurring in the corona treatment Stage of Biaxially oriented polypropylene film
ظاهرة المشكلة
efficiency decline occurs in the film during the corona treatment stage, affecting production stability and product quality.
Biaxially oriented polypropylene film is sensitive to the process parameters of this stage.
تحليل الأسباب
(1) The process parameters of the corona treatment stage are set improperly
(2) The equipment condition or precision is insufficient
(3) Raw material characteristics (biaxial stretching, longitudinal and transverse stretch ratio control, high stiffness, good transparency) cause processing difficulties
(4) The environmental conditions (temperature and humidity) are unsuitable
(5) Improper operation or inadequate monitoring
الحل
(1) Optimize the process parameters of the corona treatment stage, and control the temperature within the range of 140-170(stretching)/230-260(extrusion)°C
(2) Check and maintain the equipment to ensure operating precision
(3) Select processing process parameters suitable for biaxially oriented polypropylene film
(4) Control the temperature and humidity of the production environment
(5) Strengthen operation training and process monitoring
الخلاصة الأساسية
The process parameters of each stage of film production need to be precisely controlled; equipment condition and raw material quality are the foundation.
