Transcript of B Baloon
Potassium hydroxide – as pH adjuster (keep pH above 11 to prevent latex from coagulating)
Sulphur – to induce curing
ZDEC – to accelerate curing
Zinc Oxide – to activate curing
Anti-oxidant – to prevent oxygen attacking the rubber matrix.
Banana stem powder – induce/accelerate bio-degradation. FORMULATION OF B Balloons What is B Balloons? Effect of variable bio-filler loading on the water absorption of the latex rubber matrix. Effect of bio-filler loading on the tensile strength of the latex rubber matrix. Effect of bio-filler loading on the tear strength of the latex rubber matrix. When B Balloons are thrown away, water will enter the latex rubber matrix as the banana stem powder absorbs it. As water enters the latex rubber matrix, it will carry with it the micro-organisms found in the soil. The micro-organism can now attack the latex rubber matrix not only from the outside but also from the inside of the latex rubber matrix and thus accelerate bio-degradation. HOW IT WORKS To produce bio-degradable and eco-friendly latex balloons using bio-filler (green material) OBJECTIVES MOHAMAD BARZARIN BIN BAHARIN Microorganism Bio-filler Water B BALLOONS
Bio-degradable Balloons B balloons are biodegradable balloons that are made from latex compound containing banana stem based bio-filler as the agent for biodegradation. Thank you for lending your attention! B balloons can biodegrade within 10 weeks of exposure to the environment. A sea bird was killed due to entanglement with balloons fragments Latex balloons fragment in stomach of green turtle. How it is made? Like any other balloons,the B-balloons is made using the same process used to make normal balloons. The technique is called dipping process Dipping process is a process to make thin and hollow latex products such as gloves, condoms, balloons and toys. In principle, dipping process involves dipping cleaned formers into compounded latex and latex film will be formed around the former by drying and curing process. How do we make it in the lab?? The prototypes of B-Balloon is produced using a test tube as a former. The test tube is dip into the compounded latex made for B-Balloon The test tube is then rotated to even out the latex film formed and placed in an oven to dry up the latex to form a latex film The former being immersed into compounded latex The oven used to dry up the latex The formers available The latex after drying Preparing banana stem powder To make it finer, the banana stem powder is soaked with water and ground in a ball miller The banana stem is cut into small pieces, shredded using a blender and ground into a powder using a dry grinder Testing Result Advantages Low cost of manufacturing A more stronger balloon Animals will be unharmed Another good usage for banana plant Before After The pictures above shows the banana stem powder before and after ball milling. Notice the packed micro-fibrils became loose and formed fibre whiskers around the particles. INTRODUCTION The coloured balloons fragments are attractive to animals and trick them to think that the fragments are food. Bilions of balloon are made every year When the balloons burst, their fragments are scattered all over the earth. Balloons are made from natural rubber latex which is mixed with chemicals to form latex compound and heated at 70oC for 30 minutes to induce curing to improve properties such as strength – tensile and tear. Even though many manufacturers claimed that balloons are biodegradable, since they are made from natural rubber latex, it will take more than 1 year for latex balloons to biodegrade completely. There are many cases animal starved to death due to their digestive tract being blocked by the ingested balloons fragments Doesn't pollute the environment
