Guangzhou Wong Road, Chemical Co., Ltd. wholesale distribution of propylene glycol, diethylene glycol, ethylene glycol, triethylene glycol, anti-Whitewater, PPG, DOP selling consumer market, among consumers enjoy a higher status level glycol freeze , with many retailers and agents to establish a long-term stable cooperative relations. Wong Road, Guangzhou Chemical Co., Ltd. Distribution of propylene glycol, diethylene glycol, ethylene glycol, triethylene glycol, anti-Whitewater, PPG, DOP variety, reasonable prices. Ethylene glycol Guangzhou Wong Road Quality 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. Lun glycol, antifreeze surface tension: 46.49 mN / m (20 ℃) ??Flash point: 418 ℃ Heat of combustion: 1180.26KJ / mol at 25 ° C under freezing level where the sale of ethylene glycol, a relative dielectric constant concentration compared with 37 high hygroscopic produce synthetic resin PET, fiber level PET namely 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 decreased with increasing concentration of ethylene glycol supply freezing level, when the concentration exceeds 70%, the freezing point but rise. In the preparation process, from reality to be a reasonable choice of how much glycol freezing level 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, fast display stable repeatability, can better help our users coolant measure (name: antifreeze refractometer), to ensure the normal operation and service life of the vehicle. Which freezing level glycol, ethylene glycol Mentougou freezing level, the Wang Wong Road Chemical Road, Guangzhou Chemical Co., Ltd. to provide. Guangzhou Wong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) strong, credible, in Guangzhou cosmetic raw materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead busy road of chemical into the brilliant and you work for a better future!
