Basic knowledge and practicability of fully refined paraffin wax

Fully refined paraffin wax is a mineral wax, but also a petroleum wax; It is distilled by solvent refining, solvent dewaxing or wax freezing crystallization of crude oil, pressing the dewaxed wax paste, and then removing the wax residue of the solvent. Oil or refined tablet or needle crystal. Also known as crystalline wax, a mixture of hydrocarbons with a carbon number of about 18 to 30, consisting mainly of straight-chain alkanes (about 80 to 95 percent), and a small number of alkanes with separate branched and long side chains. Monocyclic cycloalkanes (both in total 20% or less). The main quality indicators are melting point and oil content, with the former indicating temperature resistance and the latter indicating purity. Each wax is divided into different varieties according to the melting point, generally every 2°C, such as 52,54,56,58, etc. According to the degree of processing and refining, it can be divided into three types: fully refined paraffin, semi-refined paraffin and crude paraffin. Of these, the first two are widely used, mainly as ingredients and packaging materials for food and other commodities (such as wax paper, crayons, candles, carbon paper), paints for baking containers, cosmetic ingredients, fruit preservation, and improved rubber resistance. Ageing and increased flexibility, insulation of electrical components, casting etc can also be used for oxidation to synthesize fatty acids. Due to its high oil content, crude paraffin is mainly used to make matches, fiberboard, canopy canvas and so on. When polyolefin additives are added to paraffin wax, the melting point increases, and adhesion and flexibility increase. It is widely used for moisture-proof and waterproof wrapping paper, cardboard, surface coating of certain textiles and candle production.

The nature of paraffin in the market for degreasing cleaning products: low concentration, low total cost, high cleaning efficiency, after use of the surface clean bright; And because it is a neutral product, it has no metal corrosion, especially for amphoteric metals such as copper and aluminum, no corrosion and discoloration, metal products are far better than other cleaning products cleaning protection. Chlorinated paraffins are neutral and environmentally friendly. It uses water as a diluent. It's not flammable, it's not explosive. No damage to skin, workpiece or equipment. Chlorinated paraffins are used to manufacture additive products for cables, flooring, rubber products, paints, lubricants, etc. Chlorinated paraffin 52, chlorinated paraffin 42 and chlorinated paraffin 70 have different properties, and chlorinated paraffin is commonly used.
