In other words a nonvolatile material exerts a low vapor pressure and has a slow rate of evaporation. This is a non volatile solidbut it is flammable though hard to set on fire.

Volatility is measured by vapor pressure.

Definition of non volatile matter. In oil-based paints the volatile components may be any of many organic compounds including aliphatic hydrocarbons terpenes. Analysis of nonvolatile content can be used to determine the purity of a solvent as well as to measure the amount of micro-contamination on the surface of an item or component ie. B of a computer memory.

Consider coal for example. Difficult to capture or hold permanently. Volatile matter is defined as the gases driven off when coal is heated to 950C 1742F in the absence of air under specified conditions and is consisted of short and long chain aliphatic carbon atoms linked in open chains or aromatic hydrocarbons one or more six-carbon rings characteristic of benzene series and some sulfur.

Readily vaporizable at a relatively low temperature. Volatile matter tends to not remain in one state and will rapidly transition to another state or vaporize when the right conditions are met. Volatile matter is any substance that has a tendency to vaporize given the right conditions.

For the method to be usable for unplasticized polymer dispersions and rubber latices the non-volatile residue which consists essentially of the polymeric material and of small quantities of auxiliaries such as emulsifiers protective colloids stabilizers solvents added as film-forming agents and -- especially for rubber latex concentrate -- preserving agents has to be chemically stable under the test. Less volatile substances will more readily condense from a vapor than highly volatile. Long chain extracts from crude oil tars and bitumen are technically liquids but not at all volatile.

Use the procedure in ASTM D 5403 to determine the volatile matter content of the coating except the curing test described in NOTE 2 of ASTM D 5403 is required. Nonvolatile matter is defined as the coating content remaining after all water solvents and other volatiles have been evaporated or removed. This information is useful to coating manufacturers and users for determining the total solids available in the film formation.

Volatility can also describe the tendency of a vapor to condense into a liquid or solid. In at a given temperature and pressure a substance with high volatility is more likely to exist as a vapour while a substance with low volatility is more likely to be a liquid or solid. Non-volatile residue NVR or non-volatile matter is the soluble suspended or particulate material remaining following evaporation of the volatile solvent which contains the material.

In chemistry the term nonvolatile refers to a substance that does not readily evaporate into gas under existing conditions. Not vaporizing readily a nonvolatile solvent. Volatile matter is essentially a measure of the nonwater gases formed from a coal sample during heating.

To determine water content follow section 1132. The amount of nonvolatile matter in a paint or coating can be expressed as either a weight or a volume. Flying or having the power to fly.

Having a high vapour pressure and a low boiling point. The volatile components of paint are mainly the solvents or diluents used to thin the paint. 2 of persons disposed to caprice or inconstancy.

It is measured as the weight percent of gas emissions from a coal sample that is released during heating to 950 C in an oxygen-free environment except for moisture which will evaporate as water vapor at a standardized temperature. Unlike temperature-based measurements like boiling point vapor pressure is not directly related to heat or cold and instead relies on the. Total Solids Volatile Solids Total Solids TS Dry matter content of substrate Inverse of moisture content one of the most variable parameters between substrates water Volatile Solids VS Combustible proportion of TS organic matter Non-volatile Solids Ash Inorganic material Minerals.

Of computer memory having the property of retaining data when electrical power fails or is turned off. Volatility only determines whether things are easyto set alight. A substances volatility is measured by its vapor pressure the point at which a substance turns from a solid to a gas or vice versa.

Retaining data when power is shut off. A substance that is readily vaporizable at relatively low temperature. Definition of nonvolatile.

111 Non Thin-film Ultraviolet Radiation-cured UV radiation-cured Coatings. 1 of a substance capable of readily changing from a solid or liquid form to a vapour. 3 of circumstances liable to sudden unpredictable or.

We determine volatile matter according to the procedures outlined in European Standard EN15148-2009 Solid biofuels - Determination of the content of volatile matter and we use a Carbolite Volatile Matter Furnace and special volatile matter crucibles that have been specifically designed to satisfy the requirements of this method. Definition of volatile Entry 2 of 2. In chemistry volatility is a material quality which describes how readily a substance vapourises.

Volatile matter has its volatility determined not by temperature but more so by the vapor pressure required to initiate a phase change. Volatile matter is an unstable material. In water-based latex paints this volatile component is water.
