Plastic flamingo

Thirteen Ways of Looking at a Plastic Flamingo I Amid the orange resin flower-pot The one object that did not belong Was the pink plastic flamingo II I stared into the eyes Of the pink plastic flamingo And she blankly stared back She had no emotions. III Her eyes could never shut. The pink plastic flamingo could never sleep. IV The lush lawn Was where she belonged The classroom Is her prison V The pink plastic flamingo’s legs are rigid. Her legs are numb. No matter what the…

Plastics are a material currently being used all around the world. As the production of this synthetic polymer has increased, it has become almost impossible to completely avoid interaction with a plastic material. With the discovery of this practical material, positives and negatives were discovered too. Plastics have a strong effect on the environment and human health. During manufacturing, additives are put in that can be harmful to each of these important aspects. Due to their synthetic…

2. Basic theories and principles 2.1 Chemical vapor deposition 2.1.1 Definition of chemical vapor deposition Chemical vapor deposition (CVD) is a versatile process which is widely applied to produce coatings, powders, fibers and monolithic components [1]. Applying the chemical vapor deposition, it is possible to produce alloy and compounds of metals and nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the…

polyurethanes were first developed by Otto Bayer and coworkers in 1937. Shortly thereafter, Schollenberger and coworkers used formula modification to prepare elastomeric polyurethane products from Bayer's products that were like nylon or other engineering plastics in physical characteristics. PUs are widely used in coatings, flexible and rigid foams, elastomers, and composites. Reasons for the use of polyurethane coatings include: high performance characteristics such as flexibility, toughness,…

According to cerakoteguncoatings.com (2017), Cerakote is a Polymer-Ceramic coating that can be applied to metals, plastics, polymers and wood. Cerakote is used on; knives, weapons, tools, some electronic covers, glasses and anything durable that needs a tough coating. This ceramic thin-film coating is intended to offer an appealing finish with unequaled performance. The ceramic coating of Cerakote provides the advantage of having extraordinary; adhesiveness, pliability, corrosion and wear…

In gloves industry, and for the maximum care of hands, Polyurethane-made gloves has shown the most remarkable effect than any other material. Known as one of the most versatile quality polymers, Polyurethane gloves are in huge demands at the consumer end. Well, what are the qualities that make a Polyurethane glove the best? To be honest, you can't find much stronger grip (and no sticky sensation) in a glove made by Polyurethane than any other material. The other qualities of this material are…

The polyurethane segments show high intersegment attraction such as hydrogen bonding and may be able to crystallize and form hard segments. In such polymers hard segments with Tg well above normal ambient temperature are separated by polyol soft segments, which in the mass are rubbery in nature. Hard and soft segments are arranged alternate along the polymer chain. Fig.7. Polyurethane chain configuration [32] 4.2.2. Polyurethane properties and advantages for product development…

one of the reasons why it has become popular. Insulation is necessary to protect the roof from weather getting into the cracks of the wood shingles on the roof. If left alone for a long time, this can cause some damage on the roof. Installing foam plastic on these cracks will protect the roof from further effects of weather. It is in liquid form, which expands several times its initial size when sprayed on a surface. The spray foam is polyurethane foam or SPF that is used to insulate almost…

Egg Drop Project For my egg drop project, at first I planned to do a triangle shape around the egg with straws and tape the straws together. Then I changed my project to a square like shaped with enough flexibility to squeeze the egg into it. I used straws because it would “soften” the fall. I also used a parachute to make it a smoother fall. After I completely figured out what I was doing I started building. I hot glued two straws against one straw until I had a square. After I…

Roofing Options To Consider For Your New Home If you're building a new home, then you'll get to pick out the type of roof it will have. Maybe you haven't even thought about the roof, but the type you choose will affect the appearance of your home. Plus each type has its own advantages and disadvantages. Here's a look at some of the common roofing types you can choose from. Asphalt Shingles Asphalt shingle roofs are very common. They go with all types of homes, and since most homes have them,…
