Styro Glue

CHAPTER I
INTRODUCTION
Pollution is one of the main problems the world faces today. One of the reasons is the overload of non-biodegradable objects like plastics, cans and Styrofoam. The invention of plastics and Styrofoam made a huge change in our society and it helped us in many ways. But it is also one of the main pollutants that destroy our planet. Because of these we devised a way to recycle used Styrofoam, and this is to make glue out of it. This glue can help reduce the number of Styrofoam that will be thrown away. Styrofoam is made of polystyrene beads which unravel into fine strands whenever it is melted/dissolved. Due to the unraveling of polystyrene, the Styrofoam will become a thick like gel. When it is a gel, it will be moldable and when it dries it will be very sticky. It is a very effective adhesive to glue things together. But it is not very safe since it is napalm and it can damage the lungs if it is burned. It also gives off a foul odor.

Statement of the problem 1. Will it help solve the problem of pollution in our society? 2. Will it be useful and effective? 3. What will be the effects of using the glue?
Hypothesis
It will not be effective and it will be harmful.
Theoretical Framework Theory of Plastic Deformation
There are several mathematical descriptions of plasticity. One is deformation theory (see e.g. Hooke's law) where the stress tensor (of order d in d dimensions) is a function of the strain tensor. Although this description is accurate when a small part of matter is subjected to increasing loading (such as strain loading), this theory cannot account for irreversibility.
Ductile materials can sustain large plastic deformations without fracture. However, even ductile metals will fracture when the strain becomes large enough - this is as a result of work hardening of the material, which causes it to become brittle. Heat treatment such as annealing can restore the ductility of a worked piece, so that shaping can continue.

The focus of this assignment is the comparison among the three simulations (batch of 8, batch of 4, and single price flow). While watching the 3 Styro case movies provided, we needed to analyse and compare the differences among the three simulations. There are several elements to just in time manufacturing that are crucial to the successful implementation of this new manufacturing. These elements are; Group technology, Process control quality, JIT, Uniform factory load, Pull through production and…

When you were a little kid, glue was a fun tool. It held your Popsicle houses together and it was fun to peel off your hands after it dried. But glue is not just child 's play; glue is a type of liquid that used cohesive and adhesive forces. These two forces work together to create tools that you can use in housework, at work at the office, and arts and crafts. Adhesion is the attachment of one material to another, due to a variety of potential interfaces. Adhesives are sticky substances that are…

The purpose was to see what glue would work with what substances. II. Hypothesis I think that mucilage glue would work the best with paper for all the amount of time. The glue stick would not work that well on wood but pretty good for paper. I think that white glue would not have enough time to dry for the 10 minutes but, when it has enough time to dry it would be hard to take apart. III. Materials The materials used were wood, mucilage glue, white glue, glue stick and paper. IV. Methods…

Meat Glue 457 Words Matt Carlson Rather than eating the high-priced filet mignon they paid for, restaurant customers are running the risk of receiving a bacteria-ridden compilation of meat scraps put together using an edible food adhesive known as “meat glue.” Meat glue, or more scientifically named “transglutaminase,” is an enzyme produced adhesive cooking substance made from animal blood. The glue has the ability to bond protein-containing foods together. Raw meats bound with TG are often…

Fruit Glue While the idea of gluing fruit together may sound novel, it was pointed out that the process is nothing more than an extrapolation of a fruit terrine. Still, we find that the ability to layer fruits and vegetables together is really exciting. Especially when we look beyond using just gelatin, which is the traditional bonding agent in fruit terrines and only effective at cold temperatures. Instead, we were inspired by the synergy of hydrocolloids. The first combination of ingredients…
