Stucco Types with precast instruments
Stucco is an art related to architecture, suitable for decorative arts due to its formability, ease of use and usability.
In general, stucco using precast instruments covers three categories below.
1_ Patterned (texture and surface) designs
A surface (integrated or in fragmented parts. ) is regularly laid beneath a model such as patterns on ceiling, wall, door, or plaster frame worked on the wall. At work, a patterned stucco precast parts are put together as a whole or in parts following a given pattern.
2_ Marginal designs
In this type, design is worked continuously or in splits on the ceiling sides, stairs, etc. following a special pattern.
3_ Single and special designs
This type of stucco is worked alone in special areas such as capitals, frame tops, fireplaces, entrances, etc.
Polystyrene-made precast instruments
Polystyrene is a synthetic polymer made from monomer known as styrene (a petrochemical), which is available in three types, i. e. typical, durable, and expandable polystyrene.
A) Typical polystyrene
Typical polystyrene (GPPS) is used for common goals. And usually shows properties such as high-grade heat resistance, elevated shock resistance, and acceptable fluidity during the process. It is insulated and shows high strength, which qualifies it to be used in electrical applications.
B) Durable polystyrene
This type of polystyrene possesses excellent impact resistance and is utilized in the manufacture of home appliances.
C) Expandable polystyrene (Ionolite)
Expandable polystyrene is a white polymer enriched with a volumizing agent. In Iran, it is known as Ionolite.
Compressed polystyrene foam sheets
Compressed polystyrene foam sheets are made by injection from a typical polystyrene structure containing a compact void-less intricate texture. These sheets are available at low prices. Emit no toxic gas during a fire, and show low water absorption, high insulation strength, and elevated strength.
