Chemical Properties and Physical Properties

Every raw material is include of chemicals or non chemicals. But every raw material will have chemical properties and physical properties. Chemical properties will related to the basic chemicals and the properties will talk about chemistry knowledge, while physical properties related to physical state and usually visibel but not all physical properties can be seen.

Chemical properties of goods is how that goods behave in their environment, because some material will danger if contact with water, or even danger if contact with air. For all thing that have these behavior usually include on chemicals. Chemical can be reacted to other substance, to this knowledge you must learning the basic chemistry. Chemicals usually have fuild or gas form but many of them are in solid state. All the behavior of chemicals must be state together with things they are sent to, and mentioned how the characteristic of the chemicals, how danger the chemical to human, how to treat the chemicals, and how to store the chemicals. The statement of that called as MSDS or materials datasheet.

Non chemicals sometime sensitive to the environment condition, but they don't completed with MSDS. Like iron sheet metal or carbon steel metal, they don't says the metal should be place in the environment bla bla bla, but sometimes the condition changes after long store, even only one or two weeks. This is not because of physical properties of steel but more because of chemical properties of the steel that can be reacted to the environment. There is chemical ionic bond between steel and air, so that the surface of steel become corrode. The basic course can be the environment of the store is bad or the environment of surround the place is bad, for example in arround the warehouse is chemical plants.

Physical properties is about the strength of the steel like tension of steel, brittleness, tensile strength, hardness, stiffness, and softness. Other properties can be related to chemical properties even materiial is steel like the stand to corrosion and so on.

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...

Sulfur

Sulfur or sulphur is a naturally occurring, yellow, water insoluble solid element. Its chemical symbol is S , its atomic number is 16 and its atomic weight is 32.064 sulfur is nonmetal and a member of the oxygen family of elements, which constitutes Group VIA of the periodic table. The discovery of sulfur predates recorded history, and the element has been used since ancient times. The early medical books of Dioscorides of Greece and Pliny the Elder mention sulfur, and fumes from burning sulfur were used in religious ceremonies and for fumigation. Alchemists recognized sulfur as a mineral substance that can be melted and burned. It was first classified as an element by Antonie Lavoisier in 1777. Sulfur Occurrence On earth, sulfur is widely distributed in its elemental state as a secondary mineral or as a volcanic deposit, as well as in combination with a number of metals. Large sedimentary deposits of the almost pure element, mainly of Tertiary age, are found in the coastal r...

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...
