Question

1. Why would it be difficult to recycle polyvinyl chloride into plastic bags?

2. Why is HDPE a good material for boats?

3. Which plastic do you think could best contain extremely corrosive material? Why?

4. List 2 uses of high density polyethylene other than those listed in the table.

5. 2 plastics that are targeted for recycling from household waste are polyethylene terephthalate (PETE) and high density polyethylene (HDPE). One of the problems of recycling such materials is separating them. Suppose you have been hired to set up a process for separating large quantities of waste plastic that is a mixture of PETE and HDPE. Describe how you might perform this separation.

Answer 1

1. Recycling polyvinyl chloride (PVC) into plastic bags would be difficult because PVC is made of a harder material that normal plastic bags are made of. GL with the portfolio my man.

Step-by-step explanation:

Answer 2

Step-by-step explanation:

1. It is difficult to recycle polyvinyl chloride into plastic bags because it is a very hard plastic. Polyvinyl chloride is a widely used plastic because it is durable and stable with an average life span of 30 years.

2. HDPE is a good material for boats because of its high tensile strength and low density. HDPE stands for High-density polyethylene. It is lightweight and impervious to damage.

3. HDPE. This is because it is unaffected by alkaline solution. It's corrosive nature gives it resistance to damage.

4. HDPE is used in making plastic lumber.

It is also used in producing geomembrane.

5. To separate the mixture of PETE and HDPE, you would need to employ the flotation method of separating mixtures. Mixtures are separated based on their hydrophobic and hydrophilic abilities. The mixtures are placed in a condensed tube, and stirred. The substance with a lighter weight stays at the top while the heavier one stays below. They are then removed separately.
