Paraffin wax is a mixture of solid high alkane. Paraffin wax do not react with common chemical reagents, but can be burned. Catalytic cracking reactions can occur in industry.

The chemical activity of paraffin is low, neutral, and stable chemical properties. Under normal conditions, it does not occur with acidic solution and alkaline solution.

Paraffin classification

Depending on the degree of refining processing, it can be divided into three types: full refined paraffin, semi -refined paraffin and coarse paraffin. Each type of wax is based on the melting point, which is generally divided into different varieties every 2 ° C, such as 52, 54, 56, 58 and other cards. Coarse paraffin oil content is high, mainly used to make matches, fiber boards, canvas, etc.

Macrory

Micro-crystal paraffin is mainly composed of chain linked hydrocarbons, cycloral alkanes and some linear hydrocarbons. The molecular weight range is about 500-1000. This is a relatively small crystal that is soluble in non -polar solvents and insoluble in polar solvents.

Liquid paraffin

There are many types of liquid paraffin, and their lubrication effects are different. In the early days of extrusion, the lubrication effect was good, and the heat stability was better. However, due to poor phase solution, the product is easy to become sticky when the amount is too much.

Polyethylene wax

Polyethylene wax finger molecular weight is 1500-25000 low molecular weight polyethylene or partial oxidized low molecular weight polyethylene. It is granular, white powder, block and milky white wax. Has excellent liquidity, electrical performance, and molding.

Semi -refined paraffin

For granular white solids, its relative density increases with the increase of the melting point. The product has good chemical stability, moderate oil content, good moisture -proof and insulating performance, and good plasticity. The flames of candles produced by semi -semi -refined paraffin are concentrated, smokeless, and do not cry. It is used for making candles, crayons, wax paper, general telecommunications equipment, short -circuit and light industry, chemical raw materials, etc.

Chloride

The chlorine paraffin is a golden or amber viscous liquid, which is not burning, not explosive, and volatile. It can solverate most of the organic solvents and insoluble in water and ethanol. Slowly decompose to itself above 120 ° C, which can release hydrogen chloride gas, and oxides of metal such as iron and zinc will promote its decomposition. Chlorine chloride is a auxiliary plasticizer for polyvinyl chloride. Low volatile, non -burning, odorless, non -toxic. This product replaces part of the main plasticizer, which can reduce the cost of the product and reduce the combustion. It is mainly used for polyvinyl chloride cables and water pipes, floor materials, film, artificial leather, etc.

The main application of paraffin wax

Due to the large oil content of coarse paraffin, it is mainly used to make matches, fiber boards, and canvas. After adding polyolefin additives to the paraffin, its melting point increases, adhesive and flexible, and is widely used for moisture -proof and waterproof packaging paper, cardboard, surface coating and candle production of certain textiles.

After immersion paper into the paraffin, a variety of wax paper with good waterproof performance can be used. It can be used for food, medicines and other packaging, metal rust -proof and printing industries; after adding cotton yarn, the textiles can be soft, smooth, and elastic. ; Paraffects can also be made of detergent, emulsifier, dispersant, plasticizer, lubricating fat, etc.

All refined paraffin and semi -refined paraffin are widely used. It is mainly used for food, oral medicines and some products (such as wax paper, crayons, candles, re -writing paper) components and packaging materials. , Electrical Electric
