CHAPTER I

INTRODUCTION

Our country is facing great problems with regards to the condition of our environment. Trashes everywhere, people dumping garbage on riverbanks, pollution from factories, smoke belching cars… These are the things we see around us nowadays. As students, we know that by our simple ways we can help improve the environment, and that is by RECYCLING. The group decided to choose this project because we know that by recycling and reusing simple materials, we can minimize our paper wastes and come up with a good product.

A. BACKGROUND OF THE STUDY

Carbon paper has many uses. It has a high demand in schools, offices and other institutions. The ink used in the usual production of carbon paper is expensive due to high production cost. Carbon paper-producing companies spend a lot not knowing that there is a more practical alternative to this; yet can help save our environment. In the project, carbon from used batteries was usedto serve as the pigment to produce carbon paper.

B. STATEMENT OF THE PROBLEM
v Is carbon from used batteries effective as an alternative in making inkfor carbon paper?

v What made the carbon black from used batteries a better source of pigment than the other substitutes like charcoal?

C. HYPOTHESIS
v Using the correct proportion among the vehicle and binder with thecarbon from used batteries will make it an effective alternative inmaking ink for carbon paper.

v Carbon from used batteries would be the best substitute to use for thepigment due to its fine particles.

D. OBJECTIVES OF THE STUDY

This study aims to prove that carbon from used batteries will be an effective and practical substitute in making pigment for producing carbon paper.

E. SIGNIFICANCE OF THE STUDY

This is study will enable us to know if carbon from used batteries will be an effective alternative in making ink for producing carbon paper. It will also help carbon paper-producers solve the high production cost of the product.

F. SCOPE AND LIMITATIONS OF THE STUDY

This study concentrates in the evaluation of the drying time, firmness and clarity of print of the carbon paper which made use of the black mix from batteries.

G. CONCEPTUAL FRAMEWORK

H. THEORETICAL FRAMEWORK

The basic ingredients used were acetone, coconut oil and carbon black. The acetone is the vehicle. The coconut oil is the binder. And the carbon black is the colouring pigment. The vehicle or the “surfactant” (acetone) is a wetting agent that lowers the surface tension of a liquid, allowing easier spreading and lowers the interfacial tension between two liquids. The coconut oil is the binder for it is miscible. Miscibility, in principle inchemistry, is the property of liquids to mix in all proportions, forming ahomogeneous solution. It applies in other phases such as solid and gas. The carbon black is the principal ingredient that serves as the colouring pigment. The carbon particles do not fade over time even when in sunlight or bleached. One benefit of carbon ink is that it is not harmful to the paper. Over time, the ink is chemically stable and therefore does not threaten the strength of the paper. Despite these benefits, carbon ink is not the ideal ink for permanence and ease of preservation.

REVIEW OF RELATED LITERATURE AND STUDIES

Carbon Paper

Carbon paper (originally carbonic paper) is paper coated on one side with a layer of a loosely bound dry ink or pigmented coating, usually bound with wax. It is used for making one or more copies simultaneous with the creation of anoriginal document. Manufacture of carbon paper was formerly the largestconsumer of Montan wax (also known as Lignite wax or OP wax, is a hard wax obtained by...
