What are the main purpose of the paraffin wax
Release time:2021-10-12 Number of views:1545 information sources:INNER MONGOLIA LUDINGYUAN CO.,LTD
Due to its high oil content, coarse stone wax is mainly used to make matches, fiberboard, canvas, etc. When polyolefin additives are added to paraffin, its melting point increases, adhesion and flexibility increase. It is widely used in the production of moisture-proof and waterproof packaging paper, paperboard, surface coating of some textiles and candles.
After the paper is immersed in paraffin, various wax papers with good waterproof performance can be prepared, which can be used in food, medicine and other packaging, metal rust prevention and printing industry; After paraffin wax is added to cotton yarn, the textile can be soft, smooth and elastic; Paraffin can also be used to prepare detergent, emulsifier, dispersant, plasticizer, grease and so on.
Fully refined paraffin and semi refined paraffin wax are widely used. They are mainly used for food, oral medicine and some products (such as wax paper, crayons, candles, carbon paper) components and packaging materials, coating materials for baking containers, [3] for fruit preservation, insulation of electrical components, improving rubber aging resistance and increasing flexibility, etc. [4]. 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 of phase change, small volume change in solid-liquid phase change process, good thermal stability, no supercooling phenomenon, low price and so on. Moreover, the development of aviation, aerospace, microelectronics and Optoelectronics Technology often requires that a large amount of heat dissipation generated by high-power components can only be discharged in a limited heat dissipation area and in a very short time. Compared with high melting point phase change materials, low melting point phase change materials can quickly reach the melting point and make full use of latent heat to realize temperature control, Due to its relatively short thermal response time and many advantages, paraffin wax has been widely used in high-tech systems such as aviation, aerospace, microelectronics and building energy saving.

GB 2760-96 stipulates that it is allowed to be used as gum base agent, with a limit of 50.0g/kg. It is also used for anti sticking in the production of glutinous rice paper abroad, with the dosage of 6G / kg. In addition, it is also widely used in moisture-proof, anti stick and anti oil of food packaging materials. It is suitable for food chewing gum, bubble gum and pharmaceutical positive gold oil, as well as wax directly contacting food and drugs such as heat carrier, demoulding, tablet pressing and polishing (made by cold pressing the waxy fraction of petroleum or shale oil).
