paraffin wax

Detailed Product Description

Paraffin
name: paraffin wax
Sign in CAS No. 8002-74-2
Sign in EINECS No. 232-315-6
Paraffin wax is a mineral, is a petroleum wax; it is obtained from the distillation of crude oil by solvent refining lubricating oil distillates, solvent dewaxing or wax crystallization frozen, crush dewaxing obtained paste wax, and then by solvent from oil, refined derived from the sheet or needle crystal. Also known as wax crystal shape, the number of carbon atoms is about 18 ~ 30 of the hydrocarbon mixture, the main group is divided into straight-chain alkanes (approximately 80% ~ 95%), have a small number of individual branched-chain band of the alkanes and with long side chains Single-loop Cycloalkanes (Taken together content below 20%). The main quality indicators for the melting point and oil content, the former express heat capacity, which express purity. Also according to each type of wax melting point, generally at intervals of 2 , divided into different varieties, such as brands, such as 52,54,56,58. Refined in accordance with varying levels of processing can be divided into full-refined paraffin wax, semi refined paraffin wax, and three kinds of rough. One of the two previous uses a wider, mainly for food and other commodities (such as waxed paper, crayons, candles, paper) of the components and packaging materials, containers baking coating materials, cosmetic raw materials, used in fruit preservation, improve anti-rubber aging and increased flexibility, insulating electrical components, precision casting, etc., can also be used for synthesis of fatty acid oxidation. Crude paraffin oil content because of larger, mainly used in the manufacture of matches, fibreboard, canvas canopies and so on. Paraffin add polyolefin additives, its high melting point, adhesion and flexibility increase, widely used in moisture-proof, waterproof paper, cardboard, certain textiles, surface coatings and candles production.
The use of paraffin is very extensive. Immersed in paraffin paper check after the system can have a good waterproof properties of a variety of waxed paper that can be used for food, medicine and other packaging, metal rust-proof and on the printing industry; add paraffin wax cotton will enable textile soft, smooth and there is flexibility; paraffin can also be obtained by detergent, emulsifier, dispersant, plasticizers, the most, such as grease. Because of animal and plant wax wax resources more and more nervous, and now most of the candles are manufactured in paraffin. Melting when heated paraffin, candles burning luminescence, black smoke, heat.
Paraffin about the chemical element symbols have several theories, one is paraffin are the main component of C, H of two elements in the material mixture. (May contain elements of oxygen, but that does not mainly) the chemical element symbol for CxHy. Another species that are paraffin is a mixture of several advanced alkanes, mainly n-22 is (C22H46) and n is 28 (C28H58), about 85 percent elemental carbon, hydrogen elements in about 14%. There is no single chemical element symbols.
Main information:
Also known as wax crystal shape, the number of carbon atoms is about 18 ~ 30 of the hydrocarbon mixture, the main group is divided into straight-chain alkanes (approximately 80% ~ 95%), have a small number of individual branched-chain band of the alkanes and with long side chains Single-loop Cycloalkanes (Taken together content below 20%). Paraffin are distilled from crude oil and lubricating oil distillates by solvent refining, solvent dewaxing or wax crystallization frozen, crush dewaxing obtained paste wax, and then by the de-oiling, and added refined obtained flake or needle crystal . Refined in accordance with varying levels of processing can be divided into full-refined paraffin wax, semi refined paraffin wax, and three kinds of rough. Also according to each type of wax melting point, generally at intervals of 2 , divided into different varieties, such as brands, such as 52,54,56,58. Crude paraffin oil content higher, mainly used in the manufacture of matches, fibreboard, canvas canopies and so on. The entire refining and semi-refined paraffin wax use a very wide, mainly to do with food, oral medicines and certain commodities (such as waxed paper, crayons, candles, paper) of the components and packaging materials, containers baking coating material for fruit preservation, insulating electrical components, rubber enhance anti-oxidation and increase flexibility, and so on. Can also be used for synthesis of fatty acid oxidation.
Save Note: stored in a cool, ventilated warehouse. Away from fire, heat source. Should be kept separate from oxidants, should not have mixed storage. Corresponding with the variety and quantity of fire equipment. Reserve areas should be equipped with suitable material spill port. Attachment: the specific parameters of the standard paraffin.
