Recently, the Shanghai authorities said: in order to better collect "ditch oil", Shanghai greening and city administration plan to create oil designed for the "ditch", recycle bins, to specialized recovery, it is expected that the fastest available at the Expo during the pilot. And recycling of waste oil in a large portion of it will be possible for an important chemical raw materials, of which one will apply in the coatings industry, specifically or used as roof coatings.
Waste oil as a kind of kitchen waste, source complex, containing aflatoxin, a variety of pathogens, heavy metals and other toxic and harmful components that may harm human health, food chain initially occur dizziness, headache, nausea, vomiting, diarrhea, and other symptoms of poisoning, long-term consumption light will make people lack of nutrition, accelerated aging, weight will lead to intestinal and cardiovascular diseases, gastrointestinal Mucosa, visceral severely damaged even carcinogenic. It is very typical to lift ditch oil, people always hate. "Waste oil" event always attracts attention. Extracted from the underground factories without authorization, to the surface of the clear, real dirty "ditch oil" into the table, in fact, in the "waste oil" resource utilization, many "coup". If the oil residue, that is what we call "waste oil" extracted, it would be a more effective use of the chemical areas, one is the manufacture of biodiesel, the other is used in the coatings industry.
Allegedly, the United States researchers found that waste cooking oil can be converted into a liquid compounds. Such compounds in use will become hard after, if you use it as a roof coatings, it will change depending on the temperature to heat absorption or reflection, resulting in a hot day in the reflection of light and the release of heat, cold days absorb light and save calories. Not just the United States, recently many newspapers have to waste oil recovery do extensive introduction, if used correctly, can make the waste oil. Allegedly, Japan who ditch oil manufacturing biofuels for refuse collection vehicles in use, of course, can also be used to paint.
Waste oil really may be applied in the coatings industry? already have successful use of project feasibility?? wisdom has consulted experts in the industry, currently know know, after extraction of the industrial waste oils can be used to make parts of stearic acid, fatty acid, is the production of rubber, SOAP, cosmetics, paints a raw material. But now due to a variety of conditions and factors, the paint industry in China is not a large amount of oil to use waste as an important raw material.
Hogwash surface grease can be used to make white paint production principle. Wuhan areas, for example, in the past, waste oil, the main selling after roughing to Hebei, oil chemical plant, used as raw materials for old SOAP. Now old-fashioned soap production, waste oil demand for smaller and smaller. At present, some available to paint companies of every pound of waste oil-price $ 4.1, ditch oil price per pound $ 3.8, in short supply. According to a recent Changjiang daily is about oil drilling in the flow of news reports said, Wuhan jiamei paint co., Ltd. is the main buyers of waste oil. In addition, the wisdom to go to the end of last year, Haikou qiongshan Golden Boryung decoration materials glue coating plant extract should be illegal, and waste oil pollution incidents investigated by the relevant departments. This is also because of the trench oil paint enterprises are exposed serious incidents.
In fact, due to the lack of strict supervision and management system deficiencies, especially compared to the high amount of cooking oil and profits for the lure of the main flows of waste oil is not a coating, biodiesel manufacturing, chemical enterprises, but the nationals the dinner table. It is understood that the Shanghai in 2005 to refuse resource utilization requirements, the environmental sanitation Department tried on some of the existing waste grease disposal plant for legalized "incorporation". "Waste oil" is hope through technical means into "biofuels", as well as oleic acid, stearic acid, etc. can be used for coating, fuel, and other areas of chemical raw materials. But who do not receive sufficient "ditch oil", a considerable part of the production capacity has been idle, so business is relatively bleak. How to make the waste oil in does carry out effective monitoring and recovery, reasonable to the coatings industry, in fact, there is the technology more than thinking and exploration.
