Do you know the main use of paraffin wax?

1. Use of Crude paraffin wax

Crude paraffin wax is mainly used for making matches, fiberboard, canopy canvas, etc. due to its high oil content. When polyolefin additives are added to paraffin wax, the melting point is increased, and the adhesion and flexibility are increased. It is widely used for moisture-proof and waterproof packaging paper, paperboard, surface coating of certain textiles and candle production.

After immersing the paper in paraffin wax, various wax papers with good waterproof properties can be obtained, which can be used in food, medicine and other packaging, metal rust and printing industries; after the wax is added to the cotton yarn, the textile can be soft, smooth and elastic. Paraffin wax can also be used to prepare detergents, emulsifiers, dispersants, plasticizers, greases, and the like.

2. Use of Fully refined paraffin wax and semi refined paraffin wax

Fully refined paraffin wax and semi-refined paraffin wax are widely used as food and oral medicines and components and packaging materials for certain commodities (such as wax paper, crayons, candles, carbon paper), coating materials for baking containers, for fruit preservation, electrical components insulation, improve rubber aging resistance and increase flexibility. It can also be used to oxidize to synthesize fatty acids.

As a latent heat storage material, paraffin wax wax has the advantages of large latent heat of phase change, small volume change in solid-liquid phase change process, good thermal stability, no over-cooling phenomenon and low price. The development of aerospace, aerospace, microelectronics and optoelectronic technologies often requires that a large amount of heat dissipation generated by the operation of high-power components can only be dissipated in a limited heat dissipation area and in a very short time, while a low-melting phase change material is relatively high. The melting point phase change material can quickly reach the melting point, fully utilize the latent heat to achieve temperature control, and the thermal response time is relatively short. The many advantages of paraffin wax make it widely used in various fields such as aviation, aerospace, microelectronics and other high-tech systems and house energy conservation.
GB 2760-96 is approved for use in gum bases, limited to 50.0 g/kg. It is also used for anti-sticking of rice paper production in foreign countries, and the dosage is 6g/kg. In addition, it is also widely used for moisture-proof, anti-stick and oil-proof of food packaging materials. Applicable to food chewing gum, bubble gum and pharmaceutical gold oil and other components as well as heat carrier, mold release, tableting, polishing and other direct contact with food and drugs (from the waxy fraction of petroleum or shale oil by cold pressing, etc. Method made).
