1 - a) thermal stability: a Teflon plastic material which is stable at temperatures of 260 C C, t

Modern industry has serious problems in the washer and PACKING and significant applications in the field of rotary axis electric valves, thermal integrated washer dryer power plants, sugar mills and food industry will face. Especially if high technology in producing the intended effects of the substance, the use of PTFE.
High molecular weight integrated washer dryer polymer, poly ethylene tetra-fluoride, fluorine and carbon atoms. The molecule is composed. The bonds are secured to each other. These molecules are identified with the acronyms and molecular PTFE is very difficult to use it due to its many plastic properties are recommended.
Teflon PTFE is generally "a thermoplastic polymer which is at about 327 C in order to maintain the temperature of the crystal and paste it suitable to specific manufacturing techniques creates. Shall be prepared in accordance with Parts required integrated washer dryer in the above process heat is on
1. Thermal properties of Teflon:
1 - a) thermal stability: a Teflon plastic material which is stable at temperatures of 260 C C, there is no evidence of chemical analysis at the level of a lot of your profile is preserved. Significant chemical degradation at temperatures above 400 C C is observed. And at temperatures above 500 C analysis will be faster. Tqln application in the temperature range 200 C - C to +260 C C is recommended.
1. b) crossings: PTFE molecules in the crystalline state, which varies with temperature changes. But crossings add two numbers are the different parts of the state. At 19 C C caused changes in the crystalline structure and physical properties of the crystalline state at 327 C C disappeared and a homogeneous gelatinous state of the temperature without melting of the found the geometrical shape of their is preserved.
1. c) thermal expansion: as the number (1-b) was explained by the temperature coefficient of linear expansion Teflon change direction as well as for the general case when the process occurs and PTFE components are anisotropic. In other words we can say that the linear expansion coefficient is a function of the molecule.
1 - d) thermal conductivity, thermal conductivity Teflon Teflon high temperature does not depend on the coefficient of thermal conductivity. Therefore Teflon as a good thermal insulator for others. This feature integrated washer dryer of the method of application and proper use of Teflon (PTFE mixed order) depends - for details integrated washer dryer see Tflvnhay mix.
2. a) resistance to chemical agents: Teflon practice "in front of it is chemically inert and only the alkaline metals (alkali) in the case of vulnerable elements. Teflon Flvyvrklrv Nsrflvyvr heat and high pressure integrated washer dryer are the most vulnerable.
2. b) Resistance to solvents: Teflon chemical in most solvents and temperature 300 C C does not resolve the condition causing integrated washer dryer the amount of expansion of the Teflon fluorinated Shvd.yydrvkrbnhay but this condition is reversible, but in front of some fluorinated oils to high heat 300 C C act as a solvent.
2 - d) resistance to radiation, high energy radiation, so that PTFE molecules break down their resistance to radiation resistance is of course a lot depends on the presence of oxygen. In contrast, the intensity of radiation in the air and 106 on two observed. Dielectric properties of the radiation is less affected integrated washer dryer and almost "independent of molecular weight.
2 - e) the gas permeability properties of PTFE permeability to gases, more or less similar to other plastics. Values obtained by different integrated washer dryer research is unreliable but the parts with high thickness can be considered impenetrable. It is clear that the thickness and permeability of the gas pressure in addition to a process that is ongoing and pieces that are used will depend PTFE.
3. a) resistance to tension and pressure, especially in large quantities on the process of preparing a piece of Teflon powder polymers, Teflon, however, among other in this field, and in one good resistance temperatures work long continuous heat to 260 C C wide temperature changes retains its plasticity. (Not even close to absolute zero).
3. b) resistance to bending: Teflon practice "is a matter of flexibility and even the pressure of 0.7 N / MM2 not break the course in accordance with ASTM D790)). Form a flexible plastic and Teflon at normal temperature about 50-650N / MM2 is. and stored integrated washer dryer at -80 C for about 2000N / MM2, and almost "about 200N / MM2 at 100 C C, and about 45N / MM2 at 260 C, respectively.
3. d) plastic memory: integrated washer dryer if a piece of PTFE is under pressure or tension (below the point of tears) after release, the amount of state maintained imposed. If the piece is reheated integrated washer dryer above the imposed pressure is released and the piece again "to be restored. This property is a plastic memory and Drkarbrdhay such as manufacturing and average surface roughness and is free from internal tensions .
3 - e) hardness, hardness SHORE d)) according to the standard (Astm-d 2240) between d60 and d50 is. In the event based on a standard (din 53456) measure (13.5kg for 30 seconds), hardness between 27-32
