How To Reduce The Production Cost Of Candles

The cost of making candles has become higher and higher in recent years. For this reason, candle machines, as upstream companies, should also think of ways for everyone to reduce the cost of production of candles in order to offset the pressure caused by rising wax prices. Many manufacturers began to use palm wax instead of paraffin. Introduction to Candle Materials What is Wax? Wax is a general term for a series of natural or synthetic products. "Wax" is first of all a natural organic matter used for lighting (candles), as opposed to "oil." The former is a solid at room temperature and quickly becomes a liquid after heating; the latter is a liquid at room temperature. There is also an intermediate state of "fat." The earliest wax came from animals and plants. Candles are used for religion, rituals, and decorations. Later, a variety of waxes were developed in two directions, and the concept of physical extension was the main one:

1. Physical extension: Substances that have similar physical properties to existing waxes are also called waxes. If the n-alkanes with more than 18 carbon atoms extracted from petroleum are solid at room temperature, Wenzhou bright candle machine is of good quality and soon becomes liquid after heating, which is called "paraffin";
2. Chemical extension: existing Waxes that have similar chemical structures are also called waxes. For example, n-alkanes having only 10 or 13 carbon atoms are liquid at room temperature, but they are called "liquid paraffins" because they are normal alkanes. In addition to lighting, other properties of waxes have been applied one after another and have become a large class of very important substances. For convenience, this series of products can be subdivided into: natural waxes, synthetic waxes, mineral waxes, petroleum waxes, and paraffin waxes for short. Each wax is defined by some properties such as hardness, melting point, viscosity, color, and many others.

These properties determine the main potential use of the product. In general, waxes have the following characteristics: they are solid at 20°C, from soft, elastic to brittle and hard solids; generally, at temperatures slightly above 40°C, they melt, but do not decompose and burn, and can be used as fuels. Low thermal conductivity, electrical conductivity, strong hydrophobicity.
