About the prototype model material,Resin is the main ingredient ,whereas additive such as
plasticizer, filler, lubricant ,coloring agent is auxiliary components.They are polymer organic
materials can flow folding in a certain temperature and under the action of force.The plastic
is glassy state under normal temperature,if heated,then it will be high elastic state,then turn
into a new flow pattern, which has excellent plasticity.
Synthetic resin is by one or several simple compounds through the polymerization of W/L into
a kind of high polymer compound, also known as polymers, these simple compounds are
also called monomers.The major constituents of the plastic is resin,whereas the resin is a
kind of polymeride,so to analysis the molecular structure of the plastic in essence to analysis
the molecular structure of the polymeride.
Plastics can be divided into two categories:polymerization and polycondensation reactions.
1)Polymerization reaction.It is chemical reaction of many low molecular synthesis of single
polymer .During this reaction process ,there is no low molecular substances in precipitation.
2)Associating polyethylene reaction.It is chemical reaction of many low molecular monomer
synthesis of single polymer.During this reaction process, it has low molecular substances
in precipitation.
