Polymer

1. INTRODUCTION I am a chemical engineer working for Sasol co. . The specialised scope of the company’s product portfolio include manufacturing of fuels, oils, chemical, polymers, fertilizers, explosives and gas. I am instructed to generate 5 ideas for Sasol and determine the best product (line) among them through the multi factor decision making process. I am instructed to use the AHP excel spreadsheet picking 4 criteria of my choice to evaluate the ideas. 2. IDEA GENERATION MIND MAP…

2.1. Theoretical Background 2.2. Material Selection Material selection plays an important role as the humidifier has to deal with a pressure of 2 Bar and temperature ranging from ambient to 90oC (maximum) and have to bare a load of 80 Newton. Simultaneously it should be lighter than aluminum and should be cheaper and fabricating time should be less and it should be capable of mass production and before all this it should serve the purpose. when developing plastic parts. Selection of an…

Fiber Reinforced Polymer wrapped and unwrapped concrete beams with the confinement properties. Abstract: This paper describes the experimental results of different researchers to examine the properties and behavior of lap splice reinforcement in a concrete beam. Beam specimens were constructed and tested in the lab. The beam specimen was tested with monotonic (cyclic) and fatigue loading. The beam was divided into three groups: unwrapped, wrapped with glass fiber -reinforced polymer (GFRP)…

incorporate fats, phosholipids, and steriods that don't blend well in water or by any stretch of the imagination. Proteins are organically working atoms consisitng of one or more poylpeptides that are collapsed and curled. Nucleic Corrosive is a polymer, which are made up from…

used for the nonenzymatic electrochemical detection of hydrogen peroxide (H2O2). The PpPD layer also helps the MWCNTs to be dispersed in the water together with the PB formation and fixing on the surface of the MWCNTs. Moreover, PpPD, a conductive polymer, increases the electronic conductivity and stability of MWCNTs. By combining the selectivity and catalytic capacity of PB for H2O2, a synergistic effect was observed for the H2O2 detection. The morphology and chemical composition of the…

SPE procedure was performed using a Visiprep TM-DL SPE vacuum manifold from Supelco (Bellefonte, PA, USA). Empty SPE tubes were packed with 100 mg of imprinted or non-imprinted polymer using two PTFE frits at each end. SPE cartridges were preconditioned with 2 mL of ultra pure water and 2 mL of methanol to activate the sorbent before the enrichment procedure. 8 mL of bentazon solution were uploaded onto the preconditioned cartridge…

Macromolecules Everything on Earth is made of carbon. Due to this complex molecules are formed. These complex molecules are macromolecules. Macromolecules are polymers, formed by dehydration synthesis. Dehydration Synthesis is when monomers are combines and water is removed. There are four types of macromolecules, carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates are made up of carbon, hydrogen, and oxygen. With a structural components such as glucose and sugar.…

and it was presented at the Great international exhibition six years later by none other that the man who made it Alexander Parkes. Soon after more information was collected and it had come to the conclusion that plastics were synthetic organic polymers, and the reaction plastic was formed came to be known as polymerization. The word itself derived from the greek word plastics meaning “to mold”. This essay shall be discussing how Plastics moulded the world we live in today, and what impact…

Plastic has been becoming more and more important since 1900’s and nowadays we cannot survive without it. In general, the major features of plastic are durability, light weight and low cost but these good properties also generate great problems to our environment. Current levels of use and disposal generate several environmental problems. Around 4% of crude oil is used as raw material for plastics and 3 to 4% extra are consumed to provide energy for manufacturing process. The major usage is…

Did you know that slime is a unique material composed of a cross-linked polymer. Slime has a slightly unpleasant odor and is cold and slimy to the touch. The most common color are blue, green, and red. Some people even add scents to make them smell good. People use slime to concentrate or just to play with it. It is so much fun to make slime because their are many ways to make slime, and many colors and glitters to use…
