Due to its high oil content, crude paraffin is mainly used in the manufacture of matches, fiberboards, tarpaulins, etc. The addition of polyolefin additives to paraffin raises the melting point, improves adhesion and flexibility, and is widely used in moisture and waterproof wrapping paper, corrugated board, surface coating of certain fibers, and candle making.
After soaking the paper in paraffin, you can make a variety of highly waterproof paraffin paper that can be used in the food, pharmaceutical and other packaging, metal rustproofing and printing industries.
Adding paraffin to the cotton thread can soften the fibers. Smooth and elastic. Paraffin can also be made into detergents, emulsifiers, dispersants, plasticizers, greases, etc.
Fully purified paraffin wax and semi-refined paraffin wax are widely used, mainly for foods, oral medicines, parts and packaging materials of specific products (paraffin paper, crayon, candles, carbon paper, etc.), baking container coating.
It is used as a ting material. , And for the preservation of fruits. Improves insulation of electrical parts, aging resistance of rubber and increases flexibility. It can also be used for oxidation to produce synthetic fatty acids.
As a latent heat energy storage material, paraffin has the advantages of large latent heat in the phase transition, small volume change during the solid-liquid phase transition, good thermal stability, no supercooling phenomenon, and low cost.
In addition, in the development of aerospace, microelectronics, and optoelectronic technologies, the large amount of heat dissipation produced by high power components can often be dissipated in very short time in a limited heat dissipation area. Instead, a phase change material is required.
If the melting point is low, it will be relatively high. Melting point phase change materials can reach the melting point quickly, maximize the latent heat for temperature control, and have a relatively short thermal response time.
