Hello, I am looking for someone to write an essay on Product Technology. It needs to be at least 1500 words.
They look like simple and homogenous materials, but actually they are mixtures of different kinds of materials, such as carbon black, rubber, inorganic and organic materials, wires or fabrics, designed for reinforcement and other release agents. They are intricately formed and manufactured so as to make them durable, flexible, and make them last long. There are many parameters in the design of tires to consider them as those having high quality. Tires are designed with tread, beads and sidewalls. Treads are the patterned and molded surfaces that come in contact with the road surface. The body and sidewalls gives the shape of the tire and the rubber covered beads embedded with metals and wires holds the wheel tires. The tread depth is the parameter that shows the wear and tear of the tire. It can be measured through the difference of the top of the rubber tread with the bottom of the deepest grooves of the tire. The tread wear percentage is calculated for the remaining usability of the entire tire. The maximum load for the tire is another important parameter that reveals the capacity of every tire to carry weight. The load of the tire is related to the overall size and diameter of the tire. Tires with higher loads are considered to have stronger internal construction. Another parameter considered in manufacturing tires is the inflation pressure. Every tire has an allowable recommended inflation pressure that it can contain which is measured in cold conditions. Tires are marked with their allowable inflation pressure for the general safe operation for tires with specific load ratings. The speed rating of a tire is also an important factor to consider. It is basically the maximum allowable speed that the tire is designed. For the safety of the automobile, the tire must be operated within the range of the allowable tire’s speed rating. The rotation of the tires needs to be checked as well. Tire rotation examines the rotation of the tires with regards to the position in the automobile whether they are placed in the rear or front part of the car. Correct rotational direction must be indicated in the tire to make sure that the automobile will run smoothly and efficiently (Tire Tech Information, 2012). Other parameters that contribute to the general geometry of the tires can involve the tread width, rim width and the tire’s overall diameter. The tread width measures the overall distance in between the tire’s outer and inner edges of the tread. The rim width is the required width of the rim per standards set for automobiles. The width of the rim influences the tire’s width. There are standard sizes used by manufacturers around the world. The tire’s overall diameter on the other hand is the measurement of the diameter of the tire measured from the center of the tread (Tire Tech Information, 2012). II. Materials Used for Manufacturing of Tires Tires are made of rubbers as the major raw materials. Rubber compounds are derived through the mixture of polymers, softeners, reinforcement materials and other various chemicals. Polymers used can be Natural Rubber, Isoprene Rubber, Styrene Butadiene Rubber and others. Mostly, natural rubber coming from rubber trees are the preferred materials used to manufacture tires. Rubbers are the most suitable materials for tires because they have high tear strength, wear resistance, impact resilience, and low heat generation.
