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?
It will not be effective and it will be harmful.
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. Significance of the study
* To the respondents
This study wants to inform the respondents of the growing rate of pollution in our society and do something to help lessen the amount of pollutants. * To the teachers
The teachers are informed about the capabilities and talents of their students in research activities. * To the administration
The administration is informed that the students are doing their best in school activities and discovering new ideas to improve our society. Scope and Limitations of the Study
This aims to gather all 3rd year high school students produces a research that is reliable and precise. The investigation is limited only for the study.
This study will be able to inform the public that:
* Lessening the amount of pollutants by recycling them can make a huge difference in our country. * Be creative in recycling trash into something useful.
* Recycling trash into things as small enterprises can help provide jobs to people.
Definition of Terms
Napalm - is a thickening/gelling agent generally mixed with petroleum or a similar fuel for use in an incendiary device, initially against buildings and later primarily as an anti-personnel weapon. Polystyrene - is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. Styrofoam – a type closed-cell extruded polystyrene foam.
Review of Related Literature and Studies
Polystyrene is an aromatic polymer made from the monomer styrene, a liquid hydrocarbon that is manufactured from petroleum by the chemical industry. Polystyrene is one of the most widely used plastics, the scale being several billion kilograms per year. It is a thermoplastic substance that is solid state at room temperature, but flows if heated above its glass transition temperature of about 100 °C, and becomes solid again when cooled. Pure solid polystyrene is a colorless, hard plastic with limited flexibility. It can...
