Many people can't tell organic and inorganic binders apart.
Today's dysprosium class is about the advantages and disadvantages of the two.
Organic binder basically refers to resin,
with high bond strength of mold (core) sand,
high production efficiency,
good surface quality and high dimensional accuracy of casting,
excellent falling sand performance,
high recycling rate of old sand,
these five advantages;
The disadvantages are that the raw materials
are derived from petroleum products or agricultural chemicals,
and the prices of products continue to rise.
In the process of molding (core), pouring and falling sand,
a large amount of VOC and harmful gas will be produced,
which will endanger the health of operators and pollute the environment.
Compared with organic binders,
inorganic binders have the advantages of wide sources
and cheap raw materials. And modeling (core) and casting casting, falling sand,
no VOC and other harmful gases;
Disadvantages are slow hardening speed,
low core strength; Service performance
、is very sensitive to the humidity in the environment;
Poor collapsibility;
The recycling rate of old sand is low.
Next time we will talk about the characteristics
and problems of modeling materials ~
