The process of heating natural rubber with sulphur is called vulcanization. Sulfur vulcanization may be a chemical process for changing natural rubber or related polymers into materials of variable hardness, elasticity, and mechanical durability by heating them with sulfur or sulfur-based curatives or accelerators. Sulfur forms cross-linking bridges between sections of polymer chains which have …
Textiles were the dominant industry of the industrial Revolution in terms of employment, worth of output and capital invested with. The textile industry was conjointly the primary to use modern production methods. The Industrial Revolution began in great United Kingdom, and many of the technological innovations were of British origin. By the mid-18th century United …

Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. Even if it is strongly associated with the production of thermosetting polymers, the term curing can be used for all the processes where starting from a liquid solution, …
Graphite, archaically referred to as plumbago, is a crystalline type of the element carbon with its atoms organized in a very hexagonal structure. It happens naturally during this kind and is the most stable kind of carbon under standard conditions. Under high pressures and temperatures it converts to diamond. Graphite is utilized in pencils and …
Rotary dryer Roaster is a continuous multi-zone convection system that has best drying/roasting in a mild and sanitary manner. First-in, first-out production and even heating with a sensible, step-spiral, and flighted drum design achieves uniform drying and roasting. Energy-efficient, product-focused heating maximizes heat transfer and reduces heat loss with heated air that’s focused solely into …

Injection molding is a manufacturing process for producing components by injecting melted material into a mould, or mold. Injection molding will be performed with a bunch of materials mainly including metals, glasses, elastomers, confections, and most typically thermoplastic and thermosetting polymers. Material for the half is fed into a heated barrel, mixed, and injected into …
Energy conservation is one of the key factors determining profitability and success of any unit operation. Heat transfer occurs through one of three ways, conduction, convection, and radiation. Foods and biological materials are heated primarily to increase their shelf life or to boost taste. In conventional heating that is achieved by combustion of fuels or …
PET is highly hygroscopic and absorbs moisture from the atmosphere. Tiny amounts of moisture can hydrolyse PET within the melt part, reducing molecular weight. PET should be dry just prior to processing, and amorphous PET needs crystallization prior to drying so that the particles don’t stick together as they’re going through glass transition. Hydrolysis can …
Composting is the natural process of decomposition and recycling of organic material into a humus-rich soil amendment known as compost. Food waste is composed of organic matter which can be used for composting to make fertilizer. It is an effective and eco-friendly way of disposing of food waste in your kitchen. By using leftovers and …
