What are the resins

Resins are typically viscous substances that convert into rigid polymers through a curing process. Resins are naturally occurring but are now often made synthetically. Some synthetic resins have similar properties to natural plant resins, but many are very different. Synthetic resins have several classes. Some are manufactured by the esterification of organic compounds. Some resins are more like thermosetting plastics in which the term "resin" is loosely applied to the reactant or product, or both. The term "resin" may be applied to one of two monomers in a copolymer, the other being called a "hardener.” For thermosetting plastics that only have one monomer, the sole monomer compound is called the "resin." For example, liquid methyl methacrylate is generally called the "resin" or "casting resin" when it’s in a liquid or viscous state before it polymerizes and "sets." The subsequent polymethyl methacrylate is often renamed acrylic glass or just acrylic. This article looks at 12 different types of resins and their properties and applications. Polyester Resins Polyester resins are formed from the reaction of dibasic organic acids and polyhydric alcohols. They are very flexible and have excellent resistance to heat, chemicals, and flame. They tend to be low cost. They are used for construction, laminate, auto-repair of fillers, skis, fishing rods, plane and ship components, coatings, decorative accessories, and bottles. You use Thomas' Supplier Discovery Platform to find Suppliers of Polyester Resins. Phenolic Resins Phenolic resins are a type of thermosetting resin. They are strong, heat and impact resistant and have a high resistance to chemical corrosion and the penetration of moisture. Phenolic resins are machined easily. They are used for resin impregnation, brake linings, electrical components, laminate, adhesives for cement, bonded adhesives, and molds. Alkyd Resins Alkyd resins are thermoplastic polyester resins created by heating polyhydric alcohols with polybasic acids. They have excellent electrical and thermal properties and good chemical resistance. They are low cost and used for electrical insulation, electronic components, putty fillers, and paints. Polycarbonate Resins Polycarbonate resins are thermoplastics generally developed from bisphenol A and phosgene. They have a high refractive index, electrical and thermal dimensional stability, resistance to staining, and resistance to filtration. They are used for metal replacements, safety helmets, lenses, electrical components, photography film, and insulators. You can use Thomas' Supplier Discovery Platform to find Suppliers of Polycarbonate Resins. Polyamide Resins Polyamide resins contain an amide group as a recurring part of their molecular chains. They are easily molded, strong and resistant, and lightweight. They have a low friction coefficient and are abrasion and chemical resistant. They are used for nonlubricated bearings, fibers, gears, sutures, tires, watchbands, packaging, and bottles. You use Thomas' Supplier Discovery Platform to find Suppliers of Polyamide Resins. Polyurethane Resins Polyurethane resins are copolymers made up of polyol and isocyanate components. They are very versatile when combined with other resins, and have a high film elasticity and adhesion to substrates. Polyurethane resins also have a good balance of elongation and hardness. They are used for insulation, elastomers, adhesives, and foam liners for clothing. Silicone Resins Silicone resins used to be created with sodium silicate and various chlorosilanes, but now they are often formed with the less reactive tetraethoxysilane or ethyl polysilicate and several disiloxanes. They have good thermal and oxidative stability and are flexible and water repellent. Silicone resins form hard films because of their three-dimensional network structure. They are used for rubber, laminates, encapsulated resins, defoamers, and water-resistant applications. Epoxy Resins Epoxy resins, also called polyepoxides, are a type of reactive prepolymers and polymers which contain epoxide groups. They have excellent chemical and heat resistance and strong adhesion properties. They are used for laminates, adhesives, flooring, linings, propellers, and surface coatings. Polyethylene Resins Polyethylene resins are the most common type of resin, with over 100 million tons produced annually. They have strong chemical and steam or moisture resistance and a high degree of flexibility. They are used for packaging for laminates and films, containers, cable insulation, coatings, toys, molds, linings, and pipes and tubes. You use Thomas' Supplier Discovery Platform to find Suppliers of Polyethylene Resins. Acrylic Resins Acrylic resins are related thermoplastic or thermosetting plastic substances created from acrylic acid, methacrylic acid or other related compounds. They are clear with good tensile strength. Acrylic resins are impact and UV resistant. They are used for structural and decorative panels, adhesives, elastomers, coatings, signs, and translucent tiles. Polystyrene Resins Polystyrene resins are aromatic hydrocarbon polymers made from the monomer styrene. They are low cost and easy to produce, with excellent resistance to acids, alkalis, and salts. Polystyrene resins also have good clarity and flexibility. They are used for insulation, pipes, foams, cooling towers, rubber, automotive instruments, and dashboards. Polypropylene Resins Polypropylene resins are a type of thermoplastic polymer resin that does not contain BPA. They are colorless and tasteless, with a low density and good heat resistance. They can be sterilized, so they're often used with medical equipment. Polypropylene resins also have good chemical resistance. They are used for toys, electronic components, pipe and production tubing, fibers and filaments, and coatings.

Basic knowledge & terms of solidworks

Solidworks is a product development solution that lets you conceptualize , crea, validate, communicate, mansge & transform your innovation ideas into great product design.SOLIDWORKS solutions provide easy to learn, yet extremely powerful functionality that shortens product loodevelopment time, reduces cost & improve quality.

GOLDEN RATIO in solid works

there's a common ratio found innature that can be used to create pleasing, natural looking composition in the design works , this is called the golden rario, golden ratio represent by the symbol phi and the no. Is approximately equals to 1.618. the golden ratio number can be applied to the proportion of a rectangle, called the golden rectangle. The golden rectangle is known as one of the most visually satisfying of all geometric forms. The golden ratio is appears in all forms of nature. Desigher are using the golden ratio in their design for the best visual output and natural looking.

eg. of lower & higher pairs

A lower pair is one in which there occurs a surface or area contact between two members, e.g. nut and bolts in case of higher pairs there is line or point contact between two bodied for eg. cam & rocker arms

critical speed of drum in case of rope brake dynamometer

In rope brake dynamometer , heat is genrated due to friction between rope & drum. So cooling is provided with the rope brake dynamometer . The drum is provided with flanges turned inside on the rim, forming a channel for the flow of water . Circulation of water from bottom to the top is possible onlu when centrifugal forceon water will be greater then its weight. therefore Fc >=w Fc-w=0 For equilibrium position of water in channel Fc-w=0.

grinding valve seats

The valve seat grinder rotates a grinding stone of copper shape an valve seat. A pilot installed in the valve seat . This permits the stone to clear itself of grit & dust by centrifugal force . A steel scale can be used to measure measure seat width. When a new valve is installed it may too high above the seat . Then grind the seat slightly with a stone of the same seat angle

checking of leakage of valves

1. Check valve guides for wear, clean replace & ream for same size valve steam if necessary. 2. Check valves & valve seats. Clean valve heads & steam an a wire wheel. 3. Refinish valve seats. 4. Check rocker arms for wear. Service or replace as necessary. 5. Replace valves & springs in head. 6. Check & adjust valve clearence as necessary

valve seat grinding

For effective valve seating & sealinf , the valve face is must be concentric with the valve stem . The valve seats are of two types , 1. The integral type. 2. The insert type.

valve refacing

If the valves are good enough to reuse them. This requires a valve refacing machine. The valve refacer has a grinding wheel coolant delivery system & a chuck which holds the valve for grinding set the chuck to grind the valve face at specific angle to start the operation , align the coolant feed so that it sprays coolant on the rotating valve face. Do not take heavy cuts , if so much metal must be removed that margin is loss , discard the valve.

cylinder valver

Each cylinder has two valves , an intake & exhaust valve . Some high performance engines have four valves per cylinder . Two intake & exhaust valves. Usually, the intake valves is larger than exhaust valves is opened , the only force moving air-fuel mixure into the cylinder is atmospheric preassure when exhaust valve is opened the piston is moving up & there is a high preassure driving the exhaust gases
