Guangzhou Wong Road, Chemical Co., Ltd. is a manufacturer of industrial-grade ethylene glycol, ethylene glycol mainly engaged in imported green polyester grade ethylene glycol oil level. Antifreeze is dedicated 99.9% high purity ethylene and other chemical raw materials. Professional production factory direct, spot ethylene supply stability, quality assurance; price advantage, the cash supply. We firmly believe that the good reputation from the authorized users of products, reliable and stable product resources, professional services and thoughtful intentions, we Yuanyuguangda customers partners work together! Glycol antifreeze: the extent of its reduced decline in a certain range with increasing content of ethylene glycol, but once more than a certain percentage, freezing it will rise. 55% of ethylene glycol and 45% of soft water mixed into high purity ethylene glycol antifreeze manufacturers, freezing temperature of -25 ℃; antifreeze freezing point measurement is the main component of antifreeze, antifreeze liquid accounts for 92% to 98 % antifreeze liquid can be based around the level of temperature, by mixing with water, the freezing point of control in the appropriate range. Effective antifreeze various organic alcohol. States since the 1950s, almost all use ethylene glycol as antifreeze. Ethylene glycol is a colorless, transparent, slightly sweet taste and hygroscopic viscous liquid, it is compatible with water in any proportion. The concentration of ethylene glycol is not the same. Freezing point is also different. Guangzhou Wong Road, Chemical Co., Ltd. is a manufacturer of industrial-grade ethylene glycol, ethylene glycol mainly engaged in imported green polyester grade ethylene glycol oil level. Antifreeze is dedicated 99.9% high purity ethylene and other chemical raw materials. Professional production factory direct, spot ethylene supply stability, quality assurance; price advantage glycol manufacturer stock. Lun glycol, antifreeze surface tension: 46.49 mN / m (20 ℃) ??Flash point: 418 ℃ Heat of combustion: 1180.26KJ / mol at 25 degrees Celsius, the relative permittivity of hygroscopic produce synthesis at high concentrations 37 glycol industrial grade PET resin manufacturers, namely PET fiber grade polyester fiber, bottle-grade PET used to produce mineral water bottles. Also produce alkyd resins, glyoxal, also used as antifreeze. Except as automotive antifreeze, but also for industrial refrigeration transport, are commonly called refrigerating medium, but also can be used as a condensing agent like water. The concentration of ethylene glycol is not the same. Freezing point is also different. Ethylene glycol - antifreeze freezing point of water with glycol content is not linear. Freezing its solution is not entirely decreases with increasing concentration, when the concentration exceeds 70%, the freezing point but rise. In the preparation process, from reality to be a reasonable choice to achieve frost resistance and economy requirements. In southern China, the general mass fraction of 40% glycol ratio, while in the cold north, need to take about 50% ethylene content ratio is more appropriate. PAL-91S and PAL-92S Mini Digital refractometer glycol, ethylene glycol solution specialized for measuring and displaying their concentration and freezing temperature. Its simple operation glycol factory delivery, fast display stable repeatability, can better help our users coolant measure (name: antifreeze refractometer), to ensure the normal operation of the vehicle and life . Imported green ethylene factory _ Wong Road Chemical (Online) _ Miyun County glycol factory by the Wong Road, Guangzhou Chemical Co., Ltd. to provide. Guangzhou Wong Road, Chemical Co., Ltd.
