Abstract

LINEAR LOW DENSITY POLYETHYLENE (LLDPE) DUE TO THEIR ENHANCED PROPERTIES THAN LDPE PROGRESS AND MAINTAIN THEIR PLACE IN THE INDUSTRY AND GLOBAL MARKETS. LLDPE CONVERTS BY EXTRUSION PROCESS TO PRODUCTS SUCH AS PIPES AND FILMS. SCREW IS THE MOST IMPORTANT PART OF A SCREW EXTRUDER THAT DIRECTLY AFFECTS THE PRODUCTION EFFICIENCY. PROCESS VARIABLES SUCH AS TEMPERATURE, HUMIDITY, PRESSURE, SCREW AND CYLINDER CAN BE CHANGED THE EXTRUSION PROCESS YIELD. THEREFORE ADJUSTING THE TEMPERATURE PROFILE IS A VERY IMPORTANT FACTOR IN THE MANUFACTURING PROCESS OF LINEAR LOW DENSITY POLYETHYLENE FILMS BY EXTRUDER MACHINE. IN THE PRESENT WORK THE OPTIMUM TEMPERATURE PROFILE IS OBTAINED FOR THE PRODUCTION OF A THREE-LAYER POLYETHYLENE FILMS BASED ON LLDPE. FOR THIS PURPOSE SEVERAL METHODS HAVE BEEN PROPOSED TO ACHIEVE OPTIMAL THERMAL PROFILE. THE INVESTIGATION SHOW THAT THE METHODS OF THE TEMPERATURE PROFILE REDUCTION FROM THERMAL AREA TO DIE SECTION, CONSTANT TEMPERATURE PROFILE AND CURVED TEMPERATURE PROFILE WERE DECLINED BASED ON THEIR CONTRADICTIONS IN THEORY. SO THE INCREASING PROFILE METHOD IS APPLIED IN EXPERIMENT. THE RESULTS INDICATE THAT THE THERMAL PATTERN WITH STARTING POINT OF 140 °C, STEPS TO INCREASE THE TEMPERATURE (D) EQUAL TO 5 AND MAXIMUM TEMPERATURE EQUAL TO 180 °C, LEAD TO BEST EFFICIENCY, AND IN THIS CASE THE BEST QUALITY PRODUCT WITH MINIMAL TIME AND PRICE COULD BE ESTABLISHED.
