چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولTailoring the near-surface composition profiles of pressure-sensitive adhesive films and the resulting mechanical properties.
We present a possibility of tailoring the near-surface composition profiles of pressure sensitive adhesive (PSA) films by an exposure to atmospheres of different relative humidities (RHs). The statistical copolymer P(EHA-stat-20MMA) with a majority of ethylhexylacrylate (EHA) and a minority of methylmethacrylate (MMA), being cast from a toluene based solution, is chosen as a model system. The n...
متن کاملModeling of the Peeling Process of Pressure-sensitive Adhesive Tapes with the Combination of Maxwell Elements
A simple model for the peeling process of pressure-sensitive adhesive tape is presented. The model consists of linear springs and dashpots and can be solved analytically. Based on the modeling, the curved profile of the peeling tape is spontaneously determined in terms of viscoelastic properties of adhesives. Using this model, two experimental results are discussed: critical peel rates in the p...
متن کاملProposed Method for Classifying Natural Rubber for Use in Pressure Sensitive Adhesive Tapes
Natural rubber is used as an important raw material by the pressure sensitive adhesives industry. However, the normal quality variation is relatively high compared to synthetic polymer alternatives. This paper discusses measurements of the magnitude and nature of this natural rubber quality variation using a special dynamic mechanical rheological tester. Also the paper discusses some of the cau...
متن کاملThe Effect of Pressure-Sensitive Adhesive Properties on Screenability
Pressure-sensitive adhesives (PSAs) are the major source of stickies in paper recycling. It is desirable that the PSA not break down into very small pieces during repulping so that it can be screened out. However, it is not clear in the literature what mechanical properties of PSAs are required to make PSAs screenable. In this study, the screenability of a range of PSAs was evaluated. The hydro...
