History lists of Watsons
Plastics type marks
Chemistry Project
Topic: Plastic bottles



1903
- Watsons began manufacturing distilled water in Hong Kong

1979
- Plastic containers replaced glass in the commercial sector.

1981
- Became a wholly-owned subsidiary of The Hutchison Whampoa Group.

1998

- Launch the 'Handy Bottle‘ to replace of empty water bottles.

PET
Polyethylene Terephthalate
The
main component
of plastic bottles
Thermoplastic polymer
A polyester of
Terephthalic acid
and
Ethylene glycol
The name of process:
Polymerization
Overall
Direct cooling
Indirect cooling
Blow molding
How to produce plastic bottle ?
The PET is heated and placed in a long thin tube
The tube of PET called
P-forms
Injection molding
The second stage:
Transferred into a
bottle-shaped mold
Fills highly pressurized air through
mandrel

Be blown and stretched into the mold
Cooling
The third stage:
Two cooling ways:
direct

and
indirect cooling
Carbon Dioxide
pressurized air
Water
Injection Molding
Blow Molding
Cooling
Or
Bottle manufacturing




Chemical formula:

PET

囫What are the imparts of plastic bottles?
Influence of Live (Advantages)
Easily carry out
Good material for water container
High toughness
Can be reused
Influence of Environment (Disadvantages)
Produce greenhouse gases
(N2, S2, CO2)
in oil refining
Cause the acid rain
Choke the landfills quickly and take up precious lands
Chemical formula: Acid rain
Influence of Health (Disadvantages)
Breeding the germs
Produce Diethyl Tydroxylamine (DEHA)
Release Dioxins (C4H4O2)
Both of the toxic compounds are carcinogenic
Chemical formula: releasing dioxins
Uses of recycling bottles
Fabrics for clothes
Decoration
Other plastic container
Public facilities
Toys
What are the uses of recycling bottles ?
Environmental Friendly
Government
Cooperate with environmental organization
Making new recycle bin for plastic bottles
Provide some talks about recycling plastic bottles in schools
Watsons water
Awarded the best environmental plastic bottle in 2010
Has maintained the investigation for their bottle to be more environmental
