As mentioned in the previous section, purificacion garcia dry cleaning laundry technology in cleaning solvent instead of water to help protect some of the fabrics and the typical laundry. There are many types of solvents have been used since the dry technology began in 1850, and Perc is the most common solvents. There are many articles criticizing the solvent. So what is the Perc dry cleaning industry and whether there really Perc hazardous to the health of people wear? The following article will apply Laundry Green Tech outlined the basic information about Perc Perc dry and technologies to help clients with multiple perspectives about this issue.
1. History of dry cleaning solvent: - Currently on the market and laundry industry, the most common is 02 perc and hydrocarbon solvents. Like most other inventions in the world, the discovery of alternative cleaning solvents, water happens by accident in 1849. Jean Baptiste Jolly - a French dyers discovered that the tablecloth of He became purificacion garcia cleaner when he missed purificacion garcia the maid of hands that shed light oil camphene up there. He then developed a cleaning services clothing for everyone on this accident, and that is the first step of a modern purificacion garcia dry cleaning service today. - Stubs dry cleaning industry based on two basic solvents and petroleum gasoline, but this is the type of solvent that may cause actual fire high and has caused many fires and fire period that force managers to make more rules and regulations for the sector. - After the 2nd World War ended, the chemical industry development, synthetic solvents volatile start to be produced, purificacion garcia such as carbon tetrachloride (CCl4), Trichlorethylene (C2HCl3) purificacion garcia paved the way for universal solvent Most current birth: tetrachlorethylene (Cl2C = CCl2), also known as PERC. - In the history of the development of the dry cleaning industry today, the solvents have been used include: gasoline, kerosene, glycol ethers, WhiteSpirit, D5, 113, Perc; and the current trend is to use solvents more environmentally friendly as hydrocarbons, Green Earth, Liquid CO2 and K4 system by Kreussler; which Hydrocarbon solvents are more popular. 2. Perc - Agent or push for the development of dry cleaning - can be said before Perc appearance, dry cleaning solvents are not able to meet all the requirements of users. Since the 1950s when it was first introduced Perc, dry cleaning service industry developed purificacion garcia rapidly thanks to the advantages of this type of solvent gives the ability to clean up much higher than the previous solvent stable, non-flammable and safe for most fabrics. In addition, with this type of solvent required equipments purificacion garcia little purificacion garcia more bulky, occupying less and easier purificacion garcia to install. Perc has the ability purificacion garcia to reuse and revolving thereby saving operating costs and reduce costs dry. After 12 years, until 1962, 90% of US production Perc is used in the dry cleaning industry. - Due to the characteristics and capabilities of this promising Perc gradually become dry cleaning solvents are the most popular in the world, the push for strong development of dry branches and there is also the motivation for the kinds of advanced equipment dry as we see it formed and developed. However, there are numerous concerns about the use of PERC to the wearer's health and the environment. So how is PERC; the potential for harm of PERC and whether that is safe not to dry clothes? - Perc or full name is tetrachloroethylen Chlorinated solvents, chemical formula C2Cl4 colorless liquid with a sweet odor, high evaporation capability and no fire. Perc exposure to humans primarily through respiratory absorption levels depend on many factors such as chemical concentrations, body weight, breathing rate and exposure time. Perc is difficult to absorb through skin exposure pathway should be mentioned at this! - As reported by the agency against toxins and pollutants, under the Environmental Protection Agency US EPA, after exposure to the human body, according to Perc into the lungs and blood to the organs and accumulation purificacion garcia in fat or fat-containing purificacion garcia parts. Experiments on animals taken Perc into the body through the digestive tract showed perc directly affect adipose tissue, liver and kidneys. However Perc not be transported across the placenta and therefore does not affect the fetus. The rejection Perc out mainly through breathing air and a small number in the urine. - When used properly, PERC relatively safe. However, this chemical is also likely to cause a risk to health. Negative effects of PERC common are: headache, dizziness, nausea while breathing air perc levels in excess of 100 ppm or 678 m3 / mg. 3. Dry - There is too dangerous? So whether purificacion garcia dry laundry dangerous as many people think? There are many studies and articles talking about the dangers of PERC, but to assess the risk of it affecting health service use dry cleaning is another matter, or as c
