Paraffin Introduction: paraffin wax is a mineral wax, a petroleum wax is also mainly C, H substance two elements are mixed, the chemical formula CxHy. It is a crude oil processing by-products, into a sheet or needle-like crystals, also known as crystalline wax. Technical indicators Project Quality Index Test Method Melting point ℃ ≥ ≤58GB / T253960 Oily% (m / m) ≤1.8GB / T3554 penetration (25 ℃ 100g 1 / 10mm) 23GB / T4985 light stability No. ≤7GB / T0404-soluble acid or alkali-free SH / T0407 smell, No. 2SH / T0414 color number + 30GB / T0403 mechanical impurities and moisture-free GB / T254-98 paraffin main purposes: for the production of candles, crayons, worship candle, pvc-v tube, hot melt, rubber, wire 58 degrees semi-refined paraffin wax producers, cables, sheet metal, MDF production, filled masterbatch, waterproof materials and other industries, electrical insulation, food packaging, fruit preservation, precision casting, wax paper. 54 semi-refined paraffin VGO this product as raw material, furfural refining, ketone dewaxing off the oil, add clay refining and other processing in the system, the appearance of a white solid, with a massive and granular products, and its chemical composition mainly n-paraffins, the relative density increases with the increase in melting point. 52 # -62 # semi-refined paraffin wax at a certain temperature with good plasticity, insulation, sealing and flammable, widely used in packaging, electronics, textiles, candles, crayons, matches, manufacturing and other industries. The main technical indicators of the implementation of national standards GB254-1998 58 degrees semi-refined paraffin use the table below. Experimental melting point of 58 degrees semi-refined paraffin wax, ℃ no less than 52-56; light stability, number no more than 5; colors, numbers not less than 17; kinematic viscosity (100 ℃), mm2 / s report; no water-soluble acid or alkali ;; no mechanical impurities and water use: for the production of candles; one of the materials used as crayons; used as a stencil of wax; wax material used for telecommunications; used for light industry and chemical raw materials. Features: moderate oil content, melting appropriate, tensile strength, good adhesion; refined deep level, good chemical stability; suitable crystal structure and hardness, resistance to deformation and good performance; smell of containing fewer impurities; clean and good. 50kg / bag, bag packaging with wax. Uses: used as high-frequency ceramic heat-casting process adhesives; used as a carbon paint thinners; used as a stylus dipped wax waxed hot melt material; used as a wax casting wax; used as a decorative acoustic board with wax.
