White wax is made by melting and filtering beeswax from beehives and bleaching.
Solid paraffin is a mixture of solid hydrocarbons obtained from petroleum distillation or shale crack distillation.
White wax is used as a polishing agent for sugar-coated tablets, a suppository melting point regulator, an ointment matrix, a thickener for creams, a stabilizer for water-in-oil emulsions, and a sustained-release material for solid preparations.
Solid paraffin wax is mainly used as an ointment matrix hardening ingredient and sustained-release material.
Paraffin, also known as crystalline wax, is a mixture of hydrocarbons with a carbon atom number of about 18 30, mainly composed of linear alkanes (about 80% 95%), as well as a small amount of alkanes with individual branched chains and monocyclic alkanes with long side chains (the total content of the two is less than 20%). Paraffin wax is a wax paste prepared by solvent refining, solvent dewaxing or wax freezing crystallization, pressing and dewaxing obtained from the lubricating oil fraction obtained by distillation, and then deoiled and supplemented with refined flake or needle crystals. According to the degree of processing and refinement, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin.
Each type of wax is divided into different varieties according to the melting point, generally every 2, such as 52, 54, 56, 58 and other grades. Crude paraffin wax has a high oil content and is mainly used in the manufacture of matches, fiberboard, tarpaulin, etc. Fully refined paraffin wax and semi-refined paraffin wax are widely used, mainly used as components and packaging materials for food, oral drugs and some commodities (such as wax paper, crayons, candles, carbon paper), coating of baking containers, fruit preservation, insulation of electrical components, improving rubber aging resistance and increasing flexibility, etc.
It can also be used for oxidation to produce synthetic fatty acids.

"White wax", that is, the wax secreted by the ash worm, has a high melting point and a white color, which is one of the specialties of our country.
Uses: It can be used to make candles or pill shells, and can also be used to coat wax paper, seal containers, etc.
Mount Emei white ash originated in the Sui and Tang dynasties. Legend has it that Sun Simiao (581 682), the medicine king of the late Sui and early Tang dynasties, came to Mount Emei twice to step on the deep mountains and climb the cliff to collect various Chinese herbs. Later, small insects (ash insects) were found on the branches, and soon white snow (i.e., wax flowers) grew on the branches.
Eventually, the worm turned into a moth and flew out. After testing, wax flowers have miraculous effects in treating injuries and sores, so the king of medicine mobilized the mountain people to cultivate this worm, so as to produce insects and wax, which is the origin of Emeishan white wax.
At first, in addition to the medicinal use of white wax, our people also invented candles made of white wax for lighting. In the Tang Dynasty, Buddhism prevailed, Mount Emei as one of the four famous Buddhist mountains in the country, incense flourished, and the monks and worshippers who came to burn incense to the mountain were endless.
Monks and Buddhists in Southeast Asia brought candles back to use, which is the origin of the export of Emeishan white wax. With the Song and Ming Dynasty Emeishan monks visiting India, Myanmar, North Korea, Thailand, Sri Lanka and other countries to spread Buddhist culture, the export of white ash has increased year by year.
During the Northern Song Dynasty, Taizong Taiping Xingguo 5 years (980) Wannian Temple abbot Zangzhen Zen Master used Emperor Taizong's three thousand taels of ** to cast a bronze statue of Fuxian, like high rice, weighing 62 tons, that is, made of white wax mold, cast.
Other meanings of "white wax": high-quality refined, white beeswax, also known as "white wax".
Uses: board, soil preservation, weaving, windproof, sandproof, industrial oil, construction, nectar source, garden tree, street tree, joinery, Chinese herbal medicine, papermaking.

The main uses of white ash are as follows:1. Pharmaceutical use. Li Shizhen, "Compendium of Materia Medica".
It is recorded: white ash is warm and non-toxic, can build muscle and stop bleeding, fix pain and replenish deficiency, continue tendons and bones, can kill insects when taken in pills, and can treat bald sores on the head with frequent application of white wax. The ancient books of the nuclear royal have published that the ash worm can activate the meridians, benefit the blood and replenish the middle, and can cure some internal and surgical diseases.
Such as **hematuria.
The poisonous sores have been festering for a long time.
2. Industrial use. Ash is the best material for casting models in industry such as aircraft manufacturing, machinery manufacturing and precision instrument production, light weight, smooth and clean, no deformation, high molding precision, especially for the casting of aircraft parts, adding white wax can avoid bubbles, and is a moisture-proof agent for various precision instruments and capacitors in the electronics industry, and has good anti-corrosion and insulation properties. It is a moisture-proof agent, rust inhibitor and lubricant for metal products and defense equipment.
In the paper industry, it is the polishing agent and filler of some products, and the white wax can make the paper surface smooth, dense and durable. For example, carbon paper, wax paper, glossy paper, candy paper, drawing newspapers and advanced outline paper all need to be filled with ash to lighten. In the light chemical industry, when manufacturing wax cloth, wax wire, wax rope orange car, automobile wax round, floor wax, etc., white wax is added to increase the brightness.
White wax is a polishing agent for high-end furniture, utensils, electric jade powder, etc., which can increase the beauty after being coated with white wax, and the luminosity will not fade for a long time. In addition, white wax is also a good polishing agent for the leather industry in the textile industry, which can increase the luster and toughness, firmness, beauty, and improve product quality. Therefore, the effect of bee ash is quite a lot.

Ash is the common name of the cerebroceros, the common name of the ash plant, because the tree is stocked with ash insects, so it is named ash tree, and it is a sand-fixing tree species. There are about 70 species in this genus, mainly distributed in the temperate zone of the northern hemisphere, and a few extend southward to the tropics. There are about 20 species in China.
Ash wood is tough and resistant to moisture, and can be used as furniture, farm tools, plywood, etc. <

Wax is an ester composed of higher fatty acids and higher monools, in which a small amount of free higher fatty acids, higher alcohols and higher hydrocarbons can be stored at the same time, for example, the main component of white wax in China is wax ester; The main ingredient of beeswax is palmitic acid beeswax ester.
Wax is found in the rinds of plants, the nests created by bees and other insects, the capsules of seeds, and the fur of various animals. At room temperature, wax is a shiny solid, chemically inactive, more stable than grease, difficult to be saponified, not easy to be oxidized in the air, and not easy to deteriorate.
Wax is divided into animal wax (such as insect wax, cetacet, etc.), vegetable wax (such as rice sugar wax, sugarcane wax, etc.) and mineral wax (such as lignite wax). Wax has a wide range of uses.
Wax is indispensable in the manufacture of leather oil, floor wax, glazing wax, ointment, candle, wax paper and wax patterns.
Paraffin wax is a type of mineral wax. It is also a type of petroleum wax. Translucent solids.
It is obtained by freezing or solvent dewaxing of petroleum fractions, and then deoiling and refining. It is divided into coarse paraffin, semi-refined and fully refined paraffin, edible paraffin, etc. It is used in the manufacture of candles, matches, electrical insulation materials, high-grade fatty acids and high-grade alcohols, etc.
Due to the increasing shortage of animal wax and vegetable wax resources, most candles nowadays are made of paraffin. Paraffin wax melts when heated, and candles glow, smoke, and radiate heat when burned.
