Pigments

Pigments are colored, this substance have vary there are organic and inorganic substances. Organic and inorganic insoluble substances used widely in surface coatings, but they are also employed in the ink, plastic, rubber, ceramic, paper, and linoleum industries to impart color.

A large number of pigments are dyes are consumed because different products require a particular choice of material to give maximum coverage, economy, opacity, color, durability, and desired refluctance. White lead, zinc oxide. and lithophone were once the principle of white pigments, colored pigments consisted of prusian blue, lead chromates, various iron oxides, and a few lake colors. Today titanium oxide in many varieties is almost the only white pigment used. Lead pigments, formely of major important, are now prohibited by law for many uses.

The kind example of many colored pigments are as follows:

White hiding pigments:
  • Titanium dioxide
  • Zinc oxide
  • Lithophone
  • Zinc Sulfide
  • Antimony oxide
Black pigments:
  • Carbon Black
  • Lampblack
  • Graphite
  • Iron black
Blue pigments:
  • Ultramarine
  • Copper phthalocyanine
  • Iron blue
Red pigments:
  • Red lead
  • Iron oxide
  • Cadmium reds
  • Toners and lakes
Metalics pigments:
  • Aluminum
  • Zinc dust
  • Bronze powder
Yellow pigments:
  • Litharge
  • Ocher
  • Lead or zinc chromate
  • Hanza Yellows
  • Ferrite Yellows
  • Cadmium Lithophone
Orange pigmets:
  • Basic lead chromate
  • Cadmium orange
  • Molybdenum orange
Green pigments:
  • Chromium oxide
  • Chrome green
  • Hydrated chromium oxide
  • Phthalocyanine green
  • Permansa greens (Phthalocyanine blue plus zinc chromate)
Brown pigments:
  • Burnt sienna
  • Burnt umber
  • Vandyke brown
Metal protective pigments:
  • Red lead
  • Blue lead
  • Zinc, basic lead and barium potasium chromate

Basic Chemistry

Chemistry is the physical science that deals with composition, structure and properties of substance and also the transformation that these substance that undergoes. Because the study of chemistry encompasses the entire material universe, it is central to the understanding of other science. Basic chemistry involve in all aspect on live, the incident in around you actually is the basic chemistry process such as the changes of compost from fresh there is any chemical reaction involved there even the process itself is help by microorganism. A basic chemistry theory has been formulated as the result of centuries of observation and measurement of the various elements and compounds. According to this theory, matter is composed of minute particles called atoms. The more than 100 different kinds of atoms that are known are called chemical elements. Atoms of the same elements or of different elements can combine together to form molecules and compounds. The atom are held together by forces,...

Gas Reaction and Solid Reaction

Gas Liquid Reactions When gaseous reactants are absorbed by a liquid, and a chemical reaction takes place , both chemical reaction and mass transfer may control the overall reaction rate. For analysis of this type of system should be consulted. Books by Astarita, Danckwerts, and Sherwood, Pigford, and Wilke should also be helpful. Treatments similar to these references are likewise applicable to the liquid liquid system if chemical reaction is involved in only one of two partially miscible phases and the overall rate is governed by both mass transfer and chemical reaction. Solid State Reactions The solid state reactions refer to decomposition and interaction of solids, and are generally more complex than those of other systems discussed preciously. There have been few systematic analyses of chemical reactions in the solid state. Fairly comprehensive treatments of such reactions are presented in two recent publications by Bamford and Tipper and Schmalzried respectively. Genera...

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...
