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 outlets, high levels of polyester grade ethylene glycol cash supply stability, quality assurance; price advantage, the cash supply. 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 75% ethylene content ratio is more appropriate. Wong Road since the inception of the company in line with the principle of "equality and mutual benefit, and mutual development" principle, integrity management, to win the favor of customers and love, the use of e-commerce operation, the development of trade platform, in after-sales service, tracking service, strict product quality, shape good reputation, Wang Lu Da Company profound understanding "of customers, a market," always adhere to the "win-win cooperation, enthusiastic favorable" business principles, Guangzhou polyester grade ethylene glycol, and thereby develop and nurture the development of the market, in a short period of time, and many customers had already established a good reputation and cooperative relations, and scored several major chemical plant in the agency, Wang Lu Da Company reputation first. 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. Domestic ethylene production process mainly oil path method: oil path method are petroleum or chemical products they manufacture products of ethylene oxide as raw material, and then the different reactions to obtain ethylene glycol, petroleum practical application of domestic industrial production Directions law direct hydration of ethylene oxide. Legitimate use of ethylene oxide and ethylene oxide feed water directly to the water in 190 ~ 200 ℃, 2.23 MPa under operating conditions, the reaction 0.5 h, generating glycol content of about 10% ethylene glycol, diethylene glycol, triethylene mixing an aqueous solution of ethylene glycol, ethylene glycol obtained after separation. The production process technology owned by the Anglo-Dutch major Shell Chemical Company, USA SD and UCC company, technology is mature, hot product quality polyester grade, widely used. But also a lack of domestic technology independent property rights, namely the external dependence on high technology and raw material influenced by oil prices. In addition, the process is the low selectivity of ethylene glycol, a byproduct more large high-water circulation system, energy consumption. Hot product quality polyester grade | Wong Road Chemical (certified) | Guangzhou polyester grade ethylene glycol from the Mong Road, Guangzhou Chemical Co., Ltd. to provide. Guangzhou Wong Road, Chemical Co., Ltd. (www.wangluda.com) (www.wangluda.com) is a leader in Guangzhou, cosmetic raw materials, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs. In the busy road of Chemical leadership with the staff warmly welcome all inquiries negotiations to create the prosperous road of chemical better future.
