The first people to use candles were the ancient Egyptians, who soaked the reeds' cores with melted animal fat to make wicks or torches; In ancient Rome, candles were developed and used by repeatedly impregnating rolled papyrus in melted butter or beeswax; In Japan, candles are made from wax extracted from tree nuts; In India, candles are made by boiling the fruit of cinnamon trees. In the 1820s, the French chemist MichelEugeneChevreul discovered how to extract stearic acid from animal fatty acids, thus pioneered the development and use of stearic wax, which is still popular today because of its hardness, flame resistance, and environmental protection.
With the increase in people's awareness of environmental protection, vegetable wax without adding chemical additives is favored. Cleaner, more natural soy wax products are used in the United States. At present, although candles are no longer the main light source for human beings, their popularity and use are still growing, especially in literature, art, and religion. Tealight candle for religion has a wide symbolic meaning, usually representing joy and reverence for the holy. In addition, candles are also being used in new energy sources and functional materials.
Ingredients for candles
Wax candle is mainly made of Candle's body and wick. In the selection of candle body, it can be divided into paraffin type candle and non-paraffin type candle according to the difference of the main burner. Paraffin candles are mainly used as burning-agents, while non-paraffin candles are mainly used as burning-agents, such as polyethylene glycol, trimethyl citrate, and soybean wax.
1.1Paraffin wax and modified paraffin wax most candles are paraffin wax candles.
Paraffin wax main ingredients for alkanes, there are a few branched alkanes and monocyclic naphthenes with long side chains.The melting point of high-quality candles is generally around 59.5℃. Based on the actual situation, it is determined that 58℃ paraffin wax is suitable as the raw material. In addition to paraffin wax, the main burnisher of the paraffin candle includes microcrystalline wax, synthetic wax, and modified paraffin wax such as polyethylene wax.
Tealight Candle For Religious
1.2 non-paraffin substance
1.2.1 synthetic non-paraffin substance
Non-paraffin candles require that the carbon content of the primary burner is between 40% and 60%, and that "no tears" be shed at high temperature so that no harmful substances are produced when burning. Commonly used primary combustors are ethyl carbamate, polyethylene glycol, high - grade fatty acids, and synthetic resins. Colored flame candles were prepared with ethyl carbamate, high fatty acid, or high fatty alcohol as the main combustibles, chloromolybdate as the oxidation promoter, and metal salt as the hair coloring agent. The properties of candles were studied by studying the crystallization behavior of triglyceride, triglyceride - emulsifier/stearic acid binary mixing system, and triglyceride - emulsifier - stearic acid ternary mixing system.
1.2.2 natural vegetable oil (wax) with the improvement of people's requirements for quality of life and the enhancement of environmental protection awareness, more and more people choose candles made from natural vegetable oil (wax). Plant wax is green, renewable, long burning time, not easy to produce smoke, compared with beeswax and other natural wax, it has the advantages of high output and low price.
At present, the application of vegetable wax in candles is mainly used in the combination with paraffin wax mixed candles. The candle with soybean wax as the raw material can improve the problem of the low temperature decanting of the wax in the soybean wax container. It can be seen that natural vegetable oil (wax) is used to improve the raw material of the candle, and the candle is green, clean, and environmentally friendly without harmful gas.
