The textile modification technique of calendering was used to change the cover factor wearable textiles in order improve ultraviolet protection and decrease amount radiation transmitted through fabric. Using optical microscopy spectrophotometry, quantifiable changes that occurred after repeated passes calender were measured. It found one pass uncovered area decreased by a two increased 200%. th...

graph 5100, Micromeritics) and the specific surface area was measured by nitrogen adsorption, the BET-method (ASAP 2000, Micromeritics). The particle size distribution (PSD), a narrow or broad distribution, was determined by using the equation: PSD slope=[75% (ESD)-25% (ESD)]/2.APS, where ESD means equivalent spherical diameter and APS means average particle size. Oil absorption, packing index,...

Heterogeneity of porous electrodes can cause battery failure and performance deficiencies. On the other hand, some types heterogeneity improve performance. This study uses a multi-phase smoothed particle (MPSP) model, derived from hydrodynamics (SPH) which is parameterized validated by comparison with experimental viscosity, density, electronic conductivity, MacMullin number, Young’s modulus el...

Calendering is a key yet complex manufacturing process that has varied effects on the Li-ion battery cell performance. Finding optimal compaction can require many experiments if using traditional one-factor-at-a-time method, which would be both and resource intensive. Design of Experiments (DoE) coupled with modeling via multiple linear regression (MLR) are used in this study to better understa...

The major chemical changes during the processing of rubber occur with the breakdown in mastication and during vulcanization of the molded tire. There is little chemical change during the compounding, calendering, extrusion, and molding steps. Reclaiming is the process of converting scrap rubber into an unsaturated, processible product that can be vulcanized with sulfur. Pyrolysis of scrap rubbe...

The important technological and economic advantages have expanded the use of shoe press technology to the dewatering of all paper products from pulp to tissue. Whereas the development of NipcoFlex technology began in packaging paper machines 20 years ago, this technology can today be found in virtually all applications for the mechanical dewatering of the paper web in new and modernized product...

Abstract John Vlachopoulos (JV) started his polymer processing career with the process of calendering. In two landmark papers Kiparissides, C. and Vlachopoulos, J. (1976). Finite element analysis Polym. Eng. Sci. 16: 712–719; (1978). A study viscous dissipation in calendering power-law fluids. 18: 210–214 he introduced Element Method (FEM) to solve governing equations mass, momentum, energy bas...

It’s no exaggeration to say that smartphones, whether RIM’s Blackberry, Apple’s iPhone, Google’s Android, or other models coming out every day, have become ubiquitous in government and in the population at large, and it’s no wonder. For the worker on the move, everything from email to calendering, as well as news and entertainment, is now available in a convenient pocketable device. These devic...
