Rheological Properties and Chemical Bonding of Asphalt Modified with Nanosilica

The objective of this study is to evaluate the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica. In this study, the nanosilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binders. Superpave binder and mixture tests were utilized in this study to estimate the characteristics of the nano-modifed aspha...

Modelling the Heat during the Injection Stretch Blowing Moulding: Infrared Heating and Blowing Modelling

Effects of temperature: initial heating conditions or self heating during the process, are very important during the injection stretch blow moulding (ISBM) process of PET bottles. The mechanical characteristics of the final products, which are mainly controlled by the final thickness and the orientation of the molecular chains, depend strongly on the process temperature. Modelling the heat tran...

uncrosslinked polyethylene foam production with chemical blowing agents

in many processes polymeric foams can be produced by using chemical or physical blowing agents. in this work for polyethylene foam production, the chemical blowing agents and compression moulding process were employed. at first, by using dsc diagram of two polyethylene grades, a suitable polyethylene grade was selected for foam production and then we discuss about blowing agent critical percent...

Stabilized Avocado Pastes: Chemical Contents and Oxidative Changes During Storage

The nutritive compositions and oxidative stabilities of processed avocado pastes at ambient (30±1 ̊C, RH80%) and refrigerator (5-6 o C) storage temperatures were evaluated and studied. Avocado pulp was blended with ingredients, chilled, kneaded and shaped. For oxidative studies varying concentrations and combinations of Ascorbyl palmitate (AP) and Propyl gallate (PG) were blended with the pulp. ...
