Product introduction and features
Paraffin wax, also known as crystal wax, is a kind of soluble in gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha and other non-polar solvents, insoluble in water and methanol and other polar solvents.
use
Crude paraffin is mainly used in the manufacture of matches, fiberboard and canvas due to its high oil content. After ADDING POLYOLEFIN ADDITIVE TO PARAFFIN, ITS melting point increases, its adhesion and flexibility increase, and it is widely used in the production of moisture-proof and waterproof wrapping paper, cardboard, surface coating of some textiles and candles.
The paper immersed in paraffin wax can be prepared with good waterproof performance of various wax paper, can be used in food, medicine and other packaging, metal rust and printing industry; When paraffin is added to cotton yarn, it can make the textile soft, smooth and elastic. Paraffin can also be made detergent, emulsifier, dispersant, plasticizer, grease, etc.
Fully refined paraffin and semi-refined paraffin are widely used, mainly as components and packaging materials for food, oral medicine and some commodities (such as wax paper, crayons, candles and carbon paper), as dressing materials for baking containers, for fruit preservation [3], for insulation of electrical components, and for improving the anti-aging and flexibility of rubber [4]. It can also be used for oxidation to produce synthetic fatty acids.
As a kind of latent heat energy storage material, paraffin has the advantages of large latent heat of phase transition, small volume change during solid-liquid phase transformation, good thermal stability, no undercooling phenomenon, low price and so on. In addition, the development of aviation, aerospace, microelectronics and optoelectronics technology often requires that a large amount of dissipated heat generated during the operation of high-power components can only be dissipated in a limited heat dissipation area and a very short time, while low melting point phase change materials can quickly reach the melting point compared with high melting point phase change materials, and make full use of latent heat to achieve temperature control. The relatively short thermal response time of paraffin has been widely used in various fields such as aviation, aerospace, microelectronics and other high-tech systems as well as housing energy saving.

GB 2760-96 allows the use of gum sugar base agent, the limit is 50.0g/kg. Foreign also used for sticky rice paper production, the dosage of 6g/kg. In addition, it is also widely used in food packaging materials, such as moisture-proof, anti-sticking and oil-proof. It is suitable for food chewing gum, bubblegum and medicine positive gold oil and other components as well as heat carrier, demolding, tablet pressing, polishing and other wax directly in contact with food and medicine (made from waxy fractions of oil or shale oil by cold pressing and other methods).
