Fluorine changes a technology to apply the fluorine of plastic surface mediumly to change intention in plastic treatment is the chemical reaction between photograph of a kind of solid and reactant of a kind of gas phase. Azotic fluorine gas or action of fluorine air mixture at plastic material surface, its exterior structure commutation is thin functional layer, this function layer decides material and outside have what kind of interaction and mutual effect. This reaction process is decided by reactant chroma, temperature and respective chemical function. Fluorine changes the structure that depends on plastic material of action highly as a result and chemical composition. After material passes processing, the existence of additive, the chroma of the type of additive and dye and dye causes very big effect possibly to the result. Company of German air product passes old effort, make fluorine changes a technology to answer at primary article, intermediate body and end item, open the special property that issues a regulation, can make they suit subsequently process or final utility. The technical characteristic that fluorine changes technology actually, almost all plastic surfaces can undertake pretreatment with fluorine. Because activation effect is caused by fluorine and plastic mutual reaction, because this fluorine changes the intensity of the process,can pass adjust the chroma of fluorine and emersion. The goods surface with film and complex form can be changed to handle by fluorine. According to different application circumstance fluorine changes a system to be able to divide for two sort model: , planting is successive or half successive online system, another kind is discontinuous system leaving a line. In online system, fluorine changes action happening to be in production process, for example: Producing course of the container that blow model while undertake to goods fluorine changes processing. To leaving line course, before fluorine is changed, plastic products uses vacuum box to undertake handling. It is independent that fluorine changes a course of the manufacturing process at goods. These two kinds of craft can apply in mass production. It is OK that fluorine of goods surface classics changes a technology to handle gets function cent is two kinds, one kind is to cut off function, another kind is exterior activation function. In cut off in action, the fluorine content in mixture is 1%~20% . After classics modified is handled, the surface of goods can be able to bear or endure the dissolvent that gets all sorts of kinds, for example chemical goods, organic solution, oil and fuel. The face that fluorine changes processing also can protect what plastic products makes to avoid suffer damp, vapour and the descent of all sorts of gas that contain scent. Fluorine changes the surface to be able to resist even the enroach on that bacterium and microbial place cause. Mode water sketch map and fluorine are changed for fluorine under the stability that issueing what the graph shows is fluorine carbon compound cut off different, process of processing of exterior activation function can raise the appearance can, and make the surface provides hydrophily more can. About this kind of technology the representative application in plastic treatment includes: Black-and-white pretreatment, surface constructs and stick receive, natural with man-made fibre production, film is mixed filter the production of material, production of fiber aggrandizement housing materials. Fluorine changes the blaze with the plastic advantage of processing and corona processing, these two processes all are in go up somehow damaged plastic surface, because existing,its reason is the Gao Nong that reacts easily spends reactant, plastic surface is concentrated strong oxidation, bring about polymer chemistry catenary to become not stable thereby, make can come off very easily. This means activation action to be able to disappear later in a shorter time. Low-pressure plasma also can be used at modified plastic surface, main adverse factor is the installation cost that holds low-pressure process. Additional, processing of plasma low pressure can activation only plastic most the surface layer outside. Because be in plastic the polymer catenary in always is apt activity, so activation action also can be after a very brief period disappear. Compare with the photograph of plastic finishing technology of conventional technology, fluorine changes processing to have clear advantage: ■ actually, almost all plastic surfaces can undertake pretreatment with fluorine ■ because activation effect is caused by fluorine and plastic mutual reaction,cross Cheng pilot repeatability simply, intensity is decided by the aerobic amount of existence, the process is very so easy controlled, the chroma that and can be passed adjusts fluorine comes emersion. ■ the thing surface with the endurance film of preliminary processing and complex form can be changed to handle by fluorine, fluorine changes processing to be in it is normal pressure almost (> 500bar) when, fluorine changes action to achieve inferior number of plies, preliminary processing action is met very strong because of this. ■ do not damage the surface and achieve the reactant chroma with exceedingly good lively result to be able to achieve a balance very easily, enough of this kind of chroma achieves first-rate activation effect, but it wants low to unapt attaint surface. The application that fluorine turns engineering technology is plastic the fluorine that the metropolis such as industry of concrete of fiber of container, polypropylene, coating, paint, printing ink and print, electron involves plastic product changes processing. Company of German air product uses innovation technology to undertake fluorine is changed cutting off to plastic fuel box, make the volatilization of the hydrocarbon decreases substantially, replace in order to achieve multilayer cut off crowdedly in all the effect. Through the process blowing model of newest development medium online fluorine changes technology, reduced fuel and dissolvent to diffuse mediumly from gasoline tank and plastic container apparently. The method that the tradition strengthens concrete mixture is the component such as the steel wire with inattentive interfuse, use at foundation, road surface and the building surface that do not have requirement carring capacity. Change fluorine polypropylene fiber to be added in concrete, the stability of concrete and shape the gender grows significantly, and, concrete will be lighter, life is longer. Change activation surface coating with fluorine, can improve the adherent force of paint surface significantly, make effect more lasting. Model the three-dimensional products with sophisticated shape and film can change activation face with fluorine. Additional, programmer can design its painting system, make adherent sex is achieved highest and need priming paint no longer. Between the application of semiconductor industry, achieve perfect and solid join is crucial. Accordingly, when needing chemical polish semiconductor, fluorine improves manufacturing result effectively. To make car pane edge glue slideway is slip, the manufacturer must be in glue exterior flocking or dip lacquer. Fluorine changes a technology to be able to activation glue the surface, get more durable, the slideway glue that slides more easily. Fluorine changes a technology to there still are a lot of applications in plastic treatment industry. For example the hollow container that blow model and appearance note model complexly, fiber, complex, film and foam. CNC Milling
