The use of paraffin wax hazard

Paraffin wax is mainly used to make matches, fiberboards, tarpaulins, etc. due to its high oil content. The addition of polyolefin additives to paraffin waxes increases the melting point, increases the adhesion and flexibility, and is widely used for moisture-proof, waterproof packaging paper, cardboard, surface coating of certain textiles, and candle production. The following small series introduces the use of paraffin and the hazards of paraffin.

The use of paraffin

Paraffin is a kind of petroleum processing product, a kind of mineral wax, and also a kind of petroleum wax. It is from the crude oil distillation of the lube oil fraction by solvent refining, more oil information oil information oil adjustment technology, please pay attention to the micro-account public account oil circle account is ypq0910 solvent dewaxing or wax freeze crystallization, pressing dewaxing Wax paste, then deoiled by solvent, refined or obtained by the sheet or needle crystal. Used in the manufacture of higher fatty acids, higher alcohols, matches, candles, water repellents, ointments, and electrical insulating materials.

Paraffin is divided into food grade (food grade and packaging grade, the former is excellent) and industrial grade, food grade non-toxic, industrial grade is not edible. Crude paraffin wax is mainly used for making matches, fiberboards, tarpaulins, etc. due to its high oil content. The addition of polyolefin additives to paraffin waxes increases the melting point, increases the adhesion and flexibility, and is widely used for moisture-proof, waterproof packaging paper, cardboard, surface coating of certain textiles, and candle production.

After immersing the paper in paraffin, various wax papers with good waterproof properties can be prepared, which can be used for packaging of foods, medicines, metal rust prevention and printing industries; after the wax is added to cotton yarns, the textiles can be soft, smooth and elastic. Paraffin can also be made into detergents, emulsifiers, dispersants, plasticizers, greases, etc.

The use of paraffin waxes and semi-refined paraffin waxes is very versatile. It is mainly used as a component of foods, oral medicines and certain commodities (such as wax paper, crayons, candles, carbon paper) and packaging materials, as well as coating materials for baking containers for fruit preservation. , Insulation of electrical components, improve rubber anti-aging properties and increase flexibility. It can also be used to oxidize to produce synthetic fatty acids. GB 2760-96 regulations allow the use of gum base, limited 50.0g/kg. It is also used in the anti-adhesion of glutinous rice paper production abroad, with a dosage of 6g/kg. In addition, it is also widely used in moisture-proof, anti-sticking, and oil-proof food packaging materials. Applicable to food chewing gum, bubble gum and drug gold oil and other components and heat carrier, demoulding, tableting, lighting and other direct contact with food and drug wax.

Paraffin hazards

Although paraffin can make a lot of items, it also has a certain degree of harm. Touching more will also directly affect the health of our body. Some rice on the market, many businesses in order to make money, in order to make those rice look more In order to attract people to buy, they will wax some rice, so that the whole bucket of rice looks smooth, but it can still be discerned if it is seriously seen, and the same is true for apples. The fruits we eat in our daily lives will also be When people go on paraffin, it is an illegal act to earn money and desperately think of ways to sell more goods.

Paraffin classification

1, microcrystalline wax

Microcrystalline waxes are mainly composed of chain-stranded hydrocarbons, naphthenes, and some straight-chain hydrocarbons with a molecular weight range of about 500-1000. This is a relatively fine crystal, soluble in non-polar solvents and insoluble in polar solvents.

2, liquid paraffin

There are many types of liquid paraffin and their lubricating effects are also different. In the initial stage of the extrusion process, the lubrication effect is good and the thermal stability is also good. However, due to poor compatibility, the product tends to become sticky when used in excessive quantities.

3, polyethylene wax

Polyethylene wax refers to low molecular weight polyethylene or partially oxidized low molecular weight polyethylene having a molecular weight of 1500-25000. It is in the form of granules, white powder, lumps and milky white waxes. Has excellent fluidity, electrical properties, mold release.

4, semi-refined paraffin

As a granular white solid, its relative density increases as the melting point rises. The product has good chemical stability, moderate oil content, good moisture resistance and insulation properties, and good plasticity. Candles made from semi-refined paraffin wax are concentrated, smoke-free and free from tears. Used to make candles, crayons, wax paper, general telecommunications equipment, short circuit and light industry, chemical raw materials, etc.

5, chlorinated paraffin

Chlorinated paraffin is a golden or amber viscous liquid that is non-flammable, non-explosive, and extremely volatile. It is soluble in most organic solvents, insoluble in water and ethanol. Heating to above 120°C slowly decomposes spontaneously and releases hydrogen chloride gas. Metal oxides such as iron and zinc promote decomposition. Chlorinated paraffin is an auxiliary plasticizer for polyvinyl chloride. Low volatility, non-flammable, odorless, non-toxic. This product replaces part of the main plasticizer, which can reduce the cost of the product and reduce the flammability. Mainly used for PVC cable and water pipes, floor materials, films, artificial leather and so on.

Editor's summary: The use of paraffins and the hazards of paraffins are introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
