How it is made ?What are the types of plastic ?
There is no set formula for plastic. PVC is made in a process called polymerization. It is made from the monomer 1-chloroethene: CH2=CHCl In the process of polymerization it splits in the double bond to create the polymer PolyVinyl Chloride Which looks like: -[-CH2-CHCl-]- the -[- and -]- symbolize that the polymer repeats at those points. There are some other compounds: 1. PET (PETE), polyethylene terephthalate: Commonly found on 2-liter soft drink bottles, cooking oil bottles, peanut butter jars. 2. HDPE, high-density polyethylene: Commonly found on detergent bottles, milk jugs. 3. PVC, polyvinyl chloride: Commonly found on plastic pipes, outdoor furniture, shrink-wrap, water bottles, salad dressing and liquid detergent containers. 4. LDPE, low-density polyethylene: Commonly found on dry-cleaning bags, produce bags, trash can liners, food storage containers. 5. PP, polypropylene: Commonly found on bottle caps, drinking straws, yogurt containers. 6. PS, polystyrene: Commonly found on Styrofoam peanuts, cups, plastic tableware, meat trays, take-away food clamshell containers 7. OTHER, other: This plastic category, as its name of other implies, is any plastic other than the named #1–#6, Commonly found on certain kinds of food containers, Tupperware, and Nalgene bottles. Nylon, Rayon, Synthetic Rubber etc. are also plastics.
fruits and veggies when unripe has starches as carbohydrates and converts into fructose when it ripens.
There is no single compound that that makes plastic. Most plastic materials are polymers of simple organic molecules. Polyethylene (PE) is the polymer of ethylene, C2H4, and resembles paraffin in its chemical composition: R-((CH2)2)n-R', with R and R' short undefined rests and n a very large number. Variations of this are polypropylene (one CH3 replacing one H in every second CH2), polystyrene (a benzyl-group replacing H in the same locations), polyvinyl-acetate, -chloride, -alcohol, and even Teflon. A former double-bond is caused to form a chain of single-bond molecules by ionic or radical starter molecules. Nylon is a copolymerisate of adipic acid and 1,6hexanediamine, with peptide bonds responsible for the polymerisation. A similar material is Perlon, a polymer of epsilon-caprolactam. Polycarbonate consists of a sequence of R-(O-CO)n-O-R' and is made from phosgene. Polyurethanes are similar, but with -NH- units (or substituted -NR-units) bridging the CO units. There are many more plastics, but these are some of the most common.
Fruits are the immediate method to obtain vitamins, proteins, and electrolytes, so over body may easily absorb them. Found in the case of veggie some of the straight eatable but some need to cooked well for enhance their taste.
