Ceramics More recently, one of the three largest Italian manufacturers of cookware with nonstick MONETA company has developed and released a new series of tableware Moneta Ceramica. Ordinary non-stick coating, to which we are all used, contains at its core Teflon. Teflon or politetrafluoroetilen (PTFE) is similar to the plastic material, which is used in almost every known 'not sticky' coatings are used today in the kitchen, only different number. The chemical structure of PTFE has a very complicated structure. Teflon is made up of many toxic substances that enter the food and air from the heated pan. The more often the Teflon frying pan heated to high temperature, the faster coverage starts cracking due to which small particles and volatiles into the air. In addition, during operation, usually within 2 years of use, wash utensils with Teflon hands or in the dishwasher, this process has only intensified. The company decided to develop a new Moneta non-stick coating does not contain Teflon, and produced without damage to the environment. Thanks to what appeared covering Ceramica. Superb non-stick properties were achieved by applying a ceramic coating on the basis of aluminum using nanotechnology. A layer of ceramic coating is a completely smooth monolithic coverage without any time on properties close to the glass. The main difference, resistant properties and excellent resistance to sudden temperature changes. These properties of ceramics are used as space industry in the manufacture of the outer covering of space shuttles. In Ceramica coating does not add any coloring, which explains why it is not quite...

Desired Materials Composite materials used for fibers and fabrics of various types: fiberglass, Kevlar, carbon fiber, which are sometimes reinforced with metal mesh. The second component of the composite - it bonding material: fabric can be pre-impregnated with them, it can be applied manually or automatically. As a binder used polyurethane, epoxy resins or thermoplastics with various additives. Binders determine the characteristics of the finished product by about 10%. Their choice depends on the balance of functionality, price, technology and environment. The differences between the composite and thermoplastic shells - in price, product weight and volume of production. Stamped envelope of thermoplastics under pressure in molds which are very expensive. Shell made of composite materials manufactured by matrix, which is much cheaper. However, the process is mainly carried out manually, and the cost of raw materials is much higher. In addition, the production is less, it also defines a higher price of the product of the composite. The inner layer of the helmet is made, usually of plastic foam with the addition of various additives. It may be constant or variable density, sometimes consists of several parts. The problem of the inner layer - damping abrupt accelerations. The design process starts a new helmet, especially with material selection and definition of the market, which will focus on the product. First, make sketches, then comes phase modeling in clay. On the finished model make geometric measurements, which are made stamps. This traditional method is very risky, it all depends on work experience, allowing "the eye" to assess the form, select...
