Food paraffin, paraffin food uses, food paraffin prices

Food paraffin use, food paraffin prices, Zhengzhou extraordinary chemical food manufacturers no liquid paraffin, only (25 kg a package) and bulk (50 kg a package) particles can not be removed to sell, no analytical level. Composition: a mixture of paraffin hydrocarbons. Overview: Paraffin wax is a mineral, but also a petroleum wax; it is distilled from crude oil fractions by solvent refining, solvent dewaxing or wax frozen by crystals obtained by dewaxing press paste wax, and then solvent deasphalting oil, refined flake or needle-like crystals obtained. Also known as crystalline wax, a hydrocarbon carbon atoms of about 18 to 30 was the main component is a straight-chain alkanes (about 80% to 95%), as well as a small amount of individual branched-chain alkanes and with long side chains Single cycloalkane (both total content of 20% or less). The main quality indicators for the melting point and oil content, the former showing temperature capabilities, which represents purity. Category: Every class and according to the melting point of the wax, generally every 2 ℃, divided into different varieties, such as 52,54,56,58 and other brands. Depending on the degree of processing refined, it can be divided into full-refined paraffin wax, semi-refined paraffin wax and crude paraffin three kinds. After paraffin was added polyolefin additive having a melting point higher adhesion and increased flexibility, widely used in moisture-proof, waterproof wrapping paper, cardboard, textiles and certain surface coating candle production. Role: for food, medicine and other packaging, metal rust and printing industry. 1. fully refined paraffin wax, semi-refined paraffin wider use, mainly for food and other commodities (such as wax paper, crayons, candles, carbon) components and packaging materials, baking container coating materials, cosmetics, for fruit preservation, improve rubber aging and increase flexibility, insulating electrical components, precision casting, etc., can also be used in the synthesis of fatty acid oxidation. 2. crude paraffin oil content because the more, mainly used in the manufacture of matches, fibreboard, canvas canopies and so on. 3. Preparation can have after a good waterproof paper dipped in paraffin wax paper of all kinds; 4. paraffin after adding cotton yarn, textiles make soft, smooth and have a flexible; 5. paraffin may also be obtained by detergents, emulsifiers , a dispersant, a plasticizer, the grease and the like. 6. Because animal waxes and vegetable waxes resources are increasingly strained, now mostly paraffin wax candles manufactured. Paraffin wax melts when heated, candle light burning, black smoke, heat.
