High-density polyethylene

EFFECT OF KAOLIN ON THE MECHANICAL PROPERTIES OF POLYPROPYLENE/ POLYETHYLENE COMPOSITE MATERIAL Samir Nassaf Mustafa ABSTRACT :- In this work, the mechanical and water absorption properties of polymer blend polypropylene (PP) and low density polyethylene (LDPE) at constant ratio (50/50) composites as a function of kaolin powder weight content in the grain size (100,120 µm) were investigated. Polymer composite was fabricated by mixing polymer blend ( PPLDPE) with (0, 1, 3 ,5, 10, 14) wt.% of kaolin

achieve a system with structural or functional characteristics of the best that can be achieved through one of the components alone. The vehicle has become an essential part of the day because of the material advantages such as low weight, high corrosion resistance, high strength and fatigue, and faster assembly. Used widely as raw materials in the airframe industry, packaging, electronics, medical equipment and spacecraft building materials home [1]. The increased use of composite materials for various

of polyethylene (PE), high density and linear low density polyethylene. [1] The production process involves the transportation of the liquid ethylene feedstock, via pipeline, to the plant site followed by the production of various PE resins (pellet form). These PE pellets are then sold to consumers for use in common applications such as bottles for milk and other non-carbonated drinks, drums, fuel tanks for automobiles, toys and household goods. Due to the fact that high density polyethylene (HDPE)

plastic bag”; made from high density polyethylene, but It was in the late 1970s when Plastic bags first began to terrorize the well being of humanity. More and more supermarkets in America began handing out plastic bags as if they were candy on Halloween. The more plastic bags humans use, the more natural resources are being destroyed. There are two different types of plastic bags that one may find in any supermarket, high density polyethylene (HDPE) or low density polyethylene (LDPE). There isn’t much

Like PE pipes, PP pipes weigh very little and have a lower density than water, so they float. Applications: • Sanitation piping. • Evacuation of rainwater. • Pipes without pressure. Unions: The PP pipe joining system is by melting, so that the product is welded as a single piece, without joints. 6. Multi-layer pipes:

Question 1 Polyethylene is the world’s most widely used plastic. Polyethylene plastic’s principal application was in packaging, from trash bags to milk jugs. It was widely used in the manufacture of everything from trash bags, picnic cutlery and garbage pails, to plastic toys. Polyethylene also replaced glass, wood, and metal in certain applications. There were three types of polyethylene, Low-density polyethylene, High density polyethylene and Low linear density polyethylene. Polyethylene produced

Today, global energy consumption heavily relies on fossil fuels, such as oil, coal and natural gas, in 2015, Australia relied 86% of the electricity generation on traditional non-renewable energy sources (73% coal, 13% natural gas).1 The burning of these fossil fuels has been very closely associated with carbon and greenhouse gas emission, resulting changes in the climate such as global warming and extreme weathers. The CO2 emissions had increased from estimated 198 megatons in 1850 to an astonishing

Wonder composite materials, with a power and universal lightweight relative to weight and hardness properties fell over most of the store of metals and alloys recently. Properties composite depends largely on the characteristics of its constituent materials, the distribution and the interaction between them. In general, filler is the main load bearing Members, while the matrix keeps them in the desired location and orientation, as pregnancy transfer means between the fillers and protects them from

Since 1985, America has used plastic bags due to them being waterproof and having handles making them easier to carry goods. Paper and plastic have always been a huge controversy in supermarkets through the preference of customers. Some customers prefer having the paper bags standing up straight in the trunks of their cars. Other customers prefer the plastic bags because of the handles making it easier to walk home and carry their goods. Although both preferences are fine, all customers know the

In PRO, water is transported through a semi-permeable membrane from the feed to pressurise the water on the draw side, then the pressurised water flow pushes the turbine to generate electricity. Even though the theory of harnessing power by mixing high-saline water and low-saline water was first brought up in the 1950s, and the mechanism was first proposed by Leob in 1970s. PRO was not widely accepted due its low performance. And the use of reverse osmosis (RO) membranes was found to reduce the performance
