Plastic in relation to building

Plastic is an artificial subtance that can be shaped when soft, into many different forms and has many different uses.
Plastic has become an indispensable part of the building and construction industry. Plastic in relation to building products have several distinct available advantages over traditional exterior building materias.
One advantage to the consumer is that plastic building materials typically require less maintenance than other traditional materials. Unlike wood, plastic do not swell with moisture absorption, do not need to be repainted, and do not succumb to rotting or insect infestation.
Compared to metal, plastic will not dent or rust, scratches can be buffed out and finished parts never have to be repainted.

Classification Of Plastic


plastic is classified into two types; namel:
1. Thermoset plastic;
2. Thermoplastic

-Thermoset is a term used to described plastic that become permanently hardened when heated or cured. The curing process of thermoset causes a chemical reaction that creates permanent connections between the materials molecular chains. Due to their molecular bond, thermoset plastics have superior durability and will not change shape due to estreme thermal and chemical conditions, thus often outperforming other building materials.

-Thermoplastic is a term used to described plastics that becomes soft and pliable, but do nit set when heated. Thermosetplastics have the ability to harden into a particular mould but because there is no chemical change that occurs during the curing process the materials is able to be reprocessed numerous time. The major advantage of thermoplastic materials is their ability to be recycled, though continual recycling may adversely affect the quality of the polymer.

Properties Of Plastic


1. Ductility; is a property of a plastics that that permit it to be permanently drawn, bent or twisted into varrious shape without breaking.

2. Elasticity; is that property that enable a plastic to return to its original shape when the force that causes the change of its shape is been removed.

3. Toughness; is the properties at which plastic will withstand tearing and may be stretched or otherwise deformed without breaking.

4. Hardness; this property refers to the ability of a plastic to resist abration, penetration, cutting action or permanently distortion.

Characteristic Of Plastcs used in building structures


- A plastic can be transparent like the wing screen of a vehicles.

- It can be made into insulator because it was a bad conduct of heat.

- It can be drilled, melted and casting.

- It can be weld and impressed or heated to form another object.

- Plastic material are easy interm of labour.

Uses Of Plastic


* Plastic can be used for floorinr e.g terazo floor.

* It can also be used as roofing material e.g in refugees camp and Fulanis most especially in african continent used sack and nylon for floor carpets and roofing.

* Plastic materials can be used for ceiling materials e.g pvc, nylon.

* Plastic can be used in wiring installation of a building e.g duct wiring and conduit wiring.

* Plastics are good source of materials used in construction of window, door, and furnitures such walldrobe, carbinets, chairs, among others. They can also serves as wall tilling.

* It can be used to joint items on parts of a building. Example plastic cement is used to gloed tile and water closet filling.
