High humidity maintained the content of total wax alkanes and aldehydes at sufficient levels especially c 29 alkane and c 18 aldehyde which could positively regulate the quality of the pear fruits.
Chemical composition of floor wax.
A wax is a simple lipid which is an ester of a long chain alcohol and a fatty acid.
The wax prevents the plant from losing excessive amounts of water.
The composition of cuticular wax has been studied in many whitefly species nelson et al 1998 2000 neuroptera nelson et al 2003 aphids ammar et al 2013 scale insects hashimoto and kitaoka 1982 foldi and cassier 1985 foldi 1991 and these are known to be interweave esters of long chain alcohols and fatty acids.
Paraffin waxes are mixtures of saturated n and iso alkanes naphthenes and alkyl and naphthene substituted aromatic compounds.
Four different kinds of floor polish prepared by mixing molten candle wax in paraffin wax.
A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula c n h 2n 2 such as hentriacontane c 31 h 64.
The polymer emulsions in the floor wax are created when the styrene and acrylic type monomers are joined together chemically or polymerized.
4 g candle wax 20 ml paraffin b.
8 g candle wax 20 ml paraffin c.
The aqueous emulsion composition of the present invention is completed to the final product floor polish composition by addition of general additives for a floor polish composition.
The alcohol may contain from 12 32 carbon atoms.
As such additives a wax an alkali soluble resin a wetting agent an emulsifier a dispersant a polyvalent metal compound are examples.
Although the chemical composition of the wax is always carbon and hydrogen the actual number of atoms will vary based on the exact origin of the wax.
The cuticular wax was composed of alkanes olefins fatty acids alcohols aldehydes esters and terpenoids.
Waxes are found in nature as coatings on leaves and stems.
Once polymerized the polymer used for the floor wax is suspended in water creating polymer emulsions.
A wax refiner and processor.
Treatments differ in amount of candle wax dissolved in paraffin to make the polish.
The degree of branching has an important influence on the properties.
