Transcript of Super Glue
Have made organic glues much tougher, flexible, and durable. Changes Impact Cites Timeline In 1942 Dr. Harry Coover first happened upon the super-sticky adhesive — more formally known as cyanoacrylates — by accident when he was experimenting with acrylates for use in clear plastic gun-sights during World War II. He gave up because they stuck to everything they touched. ( super glue) In 1951, a researcher named Fred Joyner, who was working with Dr. Coover at Eastman Kodak’s laboratory in Tennessee, was testing hundreds of compounds looking for a temperature-resistant coating for jet cockpits. When Mr. Joyner spread the 910th compound on the list between two lenses on a refractometer to take a reading on the velocity of light through it, he discovered he could not separate the lenses. His initial reaction was panic at the loss of the expensive lab equipment. “He ruined the machine,” Dr. Paul said of the refractometer. “Back in the ’50s, they cost like $3,000, which was huge.” Adhesive can be dated back as far as 70,000 B.C. It has been know that cavemen have used adhesive on their spears and tools for hunting. 70,000 B.C Adhesive first appeared. Made by blood, bones, skin, plants, and trees. 10,000 B.C Glue started to be made from animals 1 A.D 5,000 B.C Babylonians used glue to make their statues 18th A.D First glue factory was made. Skin, fish, bones, and casein were introduced as alternative materials. 20th A.D Modern glues were improved in flexibility, strength, and durability. 19th A.D First synthetic glues appeared. Superglue first discovered by accident. Humanity Glue lets us have shoes, houses, furniture, toys, and etc.
Provides us to bond to pieces of wood to make any home decor.
Essential to packaging and to parts assembly.
Super glue can be used in the building of houses, cars, and electronics because of its super strength and durability.
If not used correctly super glue can burn on cotton. Environment Chemical glues, like super glue, makes a hole in the ozone.
Organic glues are the greenest adhesives that have little or no impact in the environment.
If mixed with water or released in the oceans, it can disrupt the ecosystems in the water. http://en.wikipedia.org/wiki/Adhesive http://en.wikipedia.org/wiki/Cyanoacrylate http://inventors.about.com/od/gstartinventions/a/glue.htm http://machinedesign.com/article/adhesives-that-stand-up-to-harsh-chemical-environments-0419
