EVA crosslinking recycling machine 1, the radiation crosslinking: polyethylene products, such as coated polyethylene sheath of the wire, film, thin-walled pipes and other products using γ-ray, high-energy ray irradiation crosslinked ( triggered polyethylene macromolecules generate free radicals, formed CC crosslinked chains). Effect of radiation dose and temperature the degree of crosslinking by crosslinking point with increasing radiation dose increases, so by controlling the radiation conditions can be obtained with a certain degree of crosslinking of crosslinked polyethylene products. This method equipment investment, better protection facilities, ideal for fabricating a thin cross-linked products. 2, chemical crosslinking: chemical crosslinking is the use of chemical cross-linking agent to crosslink the polymer, a linear structure into a network structure. Polymer crosslinking agent should be selected depending on the species, processing technology and product performance, depending on the desired cross-linking agent in addition to meet some specific requirements, they must also have the following basic requirements: a high cross-linking, cross-linked structure stability; machining security, easy to use, affordable validity added to the resin after no too early or too late disadvantages of crosslinking; does not affect the processing properties and performance products; non-toxic, do not pollute, does not irritate the skin and eyes. In the chemical crosslinking there peroxide crosslinking, silane crosslinking, azo crosslinked points: ①, peroxide crosslinking and peroxide crosslinking a crosslinking agent, generally used organic peroxide crosslinking agent, under the influence of heat generated by the activity of radical decomposition, these radical polymer chain to generate active sites on the carbon and produce carbon-carbon cross-linked to form a network structure. The technique requires high pressure extrusion equipment, the crosslinking reaction is carried out in the barrel, and then use the quick heating of the article is heated to produce a cross-linked products. So the use of peroxide crosslinking is difficult to control the production of polyethylene pipes, unstable product quality. ②, silane cross-linking and cross-linking agent nineteen sixties successful development of silane crosslinking technology. This technique is the use of vinyl silane-containing duplexes in the role of initiator and the molten polymer reacted to form a silane-grafted polymer in the presence of a silanol condensation catalyst, water hydrolysis to form mesh siloxane chain crosslinked structure. Silane crosslinking technology because of its cross-linking using simple equipment, process is easy to control, less investment, finished high degree of crosslinking, good quality, thus greatly promoting the cross-linked polyethylene production and application. In addition to polyethylene, silane, the crosslinking need to use catalysts, initiators, antioxidants and the like. ③ Azo cross-linking which is mixed with PE in the azo compounds and azo compounds lower than the decomposition temperature of the extruder, the extrudate decompose to form free radicals by a salt bath temperature, azo compounds, polyethylene crosslinking initiator . Usually a lower melting temperature for plastic-like material cedar, there is little practical use for the plastic. http://mayu1991619.jdzj.com/ http://mayu1991619.b2b.youboy.com/ http://m1991619.cn.china.cn/ http://mayu1991619.955101.com/ http: // mayu1991619. cn.gongchang.com/ http://www.datoumao.com/gongsi/mayu1991619/ http://www.kejiqi.org/corp/mayu1991619/ http://mayu1991619.8j8.cc/ http: // mayu1991619. cn.b2b168.com// http://www.sooshong.com http://www.cntrades.com/b2b/mayu19911619/
