Raw - a material for further processing in the production.In fact, it is here that begins the release of any product.To overestimate the role of the starting material is difficult because it depends on the quality of the product.Today, there are a lot of different groups, subgroups, and commodities.Let's try to understand this diversity.
What is the raw material for the production of
collected or obtained materials are usually treated to give them a needed commodity qualities.Subsequently, they are either commercially available, or continue to participate in the subsequent production cycles, until they reach the stage of the final product.
Raw materials
classification of raw materials - this is a very relative term.Accepted provide two main groups: industrial and agricultural.It includes industrial minerals and energy.Agricultural raw materials - grain and dairy products, meat, medicinal plants.Divide all kinds of raw materials can be further into two groups: it may be a primary (mined or directly collected) and secondary (as a by-product or waste products).Second group of materials widely used in the industry that can significantly reduce costs.On the origin of all kinds of raw materials can be divided into 4 groups:
- plant origin (cereals, fruits and vegetables, herbs).
- animal origin (dairy products, animal excrement).
- mineral (natural gas, coal).
- Biosphere (water and air).
use of raw materials in the production of
Today, there are many areas of industry.List of traditional industries added every day new names, and therefore developed and used a new raw material.This is connected with the growing global demand, and emerging technologies.The most relevant direction for today is the development of energy resources.If a hundred years ago, people knew how to get energy from oil and coal, is today being actively developed, and other sources such as natural gas.There is an alternative technology for producing electricity based on natural fermentation process that acts as an energy carrier cow dung.But such production, as the production of cotton, has hardly changed over the centuries.Improved and the process is mechanized, but the raw materials are cotton bolls - the same as it was a century ago, 3-4.And the food industry is constantly changing.The desire to reduce the cost of the manufacturer turns the search for new species of the original product.The natural raw material - is the best option.Unfortunately, however, in order to save it it is often replaced by an artificial one.Thus, today it is possible to observe a situation in which some manufacturing industry continues to use any raw material for centuries, and other developing technologies and development of new types performed starting materials.
