- Basic Information
This series of refined alkane solvent oil is low in aromatic, low in sulfur and free of n-hexane. It has been tested by a third party and has an alkane content of over 99%.1. Sulfur content: sulfur dioxide in it destroys the ozone layer and pollutes the environment;2. Aromatic content / benzene content: aromatic hydrocarbons are toxic, of which benzene has the strongest effect on central nervous system and blood. Polycyclic aromatic hydrocarbons have carcinogenic effects. From the European Commission, the European Commission plans to adopt a committee regulation in the second half of 2013 to limit the content of eight polycyclic aromatic hydrocarbons (PAHs) in consumer products, including consumer goods, including toys. , clothing, shoes, gloves, sportswear, sports equipment and household appliances. Relevant enterprises that export these kinds of consumer goods to the EU must pay attention to it, and it is best to respond to work in advance. The eight polycyclic aromatic hydrocarbons mentioned in the Regulation are: benzo[a]pyrene, benzo[e]indole, benzo[a]pyrene, fused naphthalene, benzo[b]fluoranthene, Benzo[j]fluoranthene, benzo[k]fluoranthene, dibenzo[a,h]pyrene. According to the draft regulations, if the rubber or plastic parts of the product contain the above polycyclic aromatic hydrocarbons in an amount exceeding 1 mg/kg, ie 0.0001% by weight of the parts, the products cannot be placed on the market and the public. The new restrictions will apply to all relevant products placed on the market two years after the effective date of the Regulation. It is reported that polycyclic aromatic hydrocarbons are a group of substances classified as carcinogenic, mutagenic or harmful to the feces, which can be extracted and used as plasticizers. Some current migration tests have shown that materials containing high levels of PAH can release PAHs, which may be absorbed or migrated into the body after contact with the skin, leading to serious health risks. Therefore, all developed countries have imposed restrictions on PAHs in imported products: EU regulations REACH stipulates that, as of January 1, 2010, if the content of eight PAHs in tires and oils used in tire manufacturing exceeds 10 mg/kg, Or the benzo (a) hydrazine content of more than 1 mg / kg, will not be sold; Germany is also very harsh on the use of such substances, the German government mandated that the power tools sold in Germany must be tested by professional testing agencies Excess PAHs are included; in addition, the US Environmental Protection Agency lists 16 PAHs as “priority contaminants”, and PAHs must be tested before the products are listed.3. Hexane content: n-hexane is a saturated aliphatic hydrocarbon with a molecular formula of CH. (CH)CHs. Since n-hexane is hardly soluble in water and soluble in ether and alcohol, it is widely used as a solvent in the industry, such as catalytic reforming in the petroleum processing industry, crude oil leaching in food manufacturing, propylene solvent recovery in plastics manufacturing, and daily use. Decontamination cleaning agents used in the chemical industry for floral solvent extraction, printing hardware and electronics, adhesives used in leather footwear, etc. I chemical products such as powder, varnish, white oil, open glue, open water All contain n-hexane. Some products contain not only n-hexane and isomers, but also other C" aliphatic hydrocarbons such as 2-methylpentane, 3-methylpentane, 2,3 dimethylbutane, and rings. Pentane and cycloisohexane, etc. Chronic poisoning of n-hexane. In 1957, Italy first reported the case of "shoemaker's toxic peripheral neuropathy", and subsequent analysis was suspected to be related to exposure to n-hexane. Japan suffered severely in the 1960s. Chronic poisoning accident of n-hexane, and systematic reports of peripheral neuropathy caused by n-hexane poisoning. In 1968, Japan reported that 1,662 people were produced in the plastic sandal factory, and 93 of them developed peripheral neuropathy due to exposure to n-hexane. In 21 new cases, the exposure concentration was only 176 mg/m3. In 1986, Wang of Taiwan reported that 15 workers were poisoned by a printer who cleaned the machine with an organic solvent containing n-hexane. The contact concentration was 74-669 mg/m3. Other countries and regions such as the United States, Canada, Europe, Brazil, South Africa and Hong Kong of China have also reported. In 1990, Zhu Xihui reported 6 cases of acute poisoning accidents in a grease factory, 2 of which were strict Intoxication appeared in a coma. In 1997, Li Yanmei and others reported that the extract of a fat oil factory leaked, and its main component was n-hexane, which led to an acute poisoning. The case left sequelae after the acute phase, and the lower limbs were weak and the numbness of the numbness was 7 More than a month. In 2000, He Jiatun and other reports on the occupational hazard of 140 cases of chronic hexane poisoning in Shenzhen. In July 2001, the province has diagnosed 49 cases of occupational chronic hexane poisoning. According to the survey, the poisoned persons accounted for 38.7% of the staff, the main types of work are sponges or veneers. The powder used has been tested to contain 8.8% to 27.7% of n-hexane, with an average of 19.5%. In 2010, Suzhou Lianjie broke out again. The "Apple Gate" event.
