The lubricity theory, free volume theory and the gel theory are three theories that explain the plasticization of rubber compounds. The lubricity theory suggests that plasticizers improve the lubrication between the polymer chains in the rubber compound, which allows for easier movement and greater flexibility. According to this theory, the plasticizer molecules are inserted between … Continued
What is Plasticization? Plasticization of a rubber compound refers to the process of adding plasticizers to the rubber to improve its flexibility, workability, and other properties. A plasticizer is a chemical compound that is added to a material to make it more pliable and easier to shape. In the case of rubber, plasticizers are added … Continued
Value Stream Mapping (VSM) is a lean management tool used to analyze and visualize the flow of materials, information, and activities required to bring a product or service to the customer. The objective of value stream mapping is to identify waste and opportunities for improvement within the value stream. In value stream mapping, the value … Continued
“Muda” is a Japanese term that refers to any activity that does not add value to the product or service being produced. In lean manufacturing, eliminating muda is a key strategy for improving productivity and efficiency. One type of muda that can have a negative impact on creativity in the workplace is “lost creativity.” This … Continued
Adopt a new philosophy. Adopt and institute leadership. Drive out fear. Break down barriers between staff areas. Eliminate slogans, exhortations, and targets for the workforce. Remove barriers that rob people of pride of workmanship – W. Edwards Deming
A C-shaped manufacturing cell is a type of manufacturing layout that is designed to optimize efficiency and productivity in a manufacturing process. It is named for its C-shaped configuration, which allows for a streamlined flow of materials and products through the production process. In a C-shaped manufacturing cell, the production equipment is arranged in a … Continued
The Arrhenius equation is a mathematical relationship that describes the effect of temperature on the rate of chemical reactions. It was first proposed by the Swedish chemist Svante Arrhenius in 1889. The equation is given by: where k is the rate constant of the reaction, A is the pre-exponential factor (or frequency factor), Ea is … Continued
Goldratt’s Critical Chain is a project management methodology that emphasizes the importance of identifying and managing the most critical tasks in a project in order to ensure its successful completion. The methodology was developed by Eliyahu Goldratt, a physicist and management consultant, and was first presented in his book “Critical Chain” in 1997. The critical … Continued
Plasticizers are a type of additive used in rubber compounds to improve their flexibility, durability, and other physical properties. They are often added to rubber formulations to make the material softer and more pliable, while also improving its resistance to cracking, abrasion, and other forms of wear and tear. There are many different types of … Continued
Processing aids are a class of additives that are used in rubber compounds to improve processing characteristics, such as flow and dispersion, and to enhance the final properties of the cured rubber product. There are many different types of processing aids that can be used, and their selection depends on the specific application and processing … Continued
