A.Background of the Study
The scientific name of glue is “Cyanoacrylates”.
Glue is the chief topic in this investigatory project. Glue is widely used worldwide. From schools to offices, from homes to buildings, glue is always present to help in individuals in their daily lives. This material can be used in simple works or as an emergency utensil; from torn books to stripped parts of paper works; this tool is very significant in our lives.
Glue is a sticky material (usually a liquid) that can stick two or more things together. Glue can be made from plant or animal parts, or it can be made from oil-based chemicals. The first glues may have been natural liquids that come out ...view middle of the document...
In making their school projects and they have projects to make in their respective houses.
The people who will benefit from this home-made glue are the following:
1st are we, as a Student we all need glue to sticking our test results in our notebooks.
2nd is the people who works in the office might need glue because they use it as the paste their finished product to be submitted to their boss.
3rd is the teachers, they will need in order to paste the students test result in the notebook.
D.Scope and Limitations
The limitations of the homemade is glue is
II. Review of Literature
A.Review of Literature
When I searched Google about the homemade glue, there were many related study. Some use cassava flour in making glue some use Styrofoam, honey in making. When I found out that milk can also be used as alternative glue combining with the other ingredients in making homemade glue.
The glue that I’ll be experimenting is called “Casein Glue.”
Casein glue is the name for a family of related phosphoproteins (αS1, αS2, β, κ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow milk and between 20% and 45% of the proteins in human milk. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to a binder for safety matches. As a food source, casein supplies amino acids, carbohydrates, and the two inorganic elements calcium and phosphorus.
Milk is a white liquid produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest other types of food. Early-lactation milk contains colostrum, which carries the mother's antibodies to the baby and can reduce the risk of many diseases in the baby. It also contains many other nutrients. As an agricultural product, milk is extracted from mammals during or soon after pregnancy and used as food for humans. Worldwide, dairy farms produced about 730 million tons of milk in 2011. India is the world's largest producer and consumer of milk, yet neither exports nor imports milk. New Zealand, the European Union's 28 member states, Australia, and the United States are the world's largest exporters of milk and milk products. China and Russia are the world's largest importers of milk and milk products. Throughout the world, there are more than 6 billion consumers of milk and milk products. Over 750 million people live within dairy farming households. Milk is a key contributor to improving nutrition and food security particularly in developing countries. Improvements in livestock and dairy technology offer significant promise in reducing poverty and malnutrition in the world.
