It sets and its furnace drying method.
Background technique
Perfluoroethylene-propylene FEP or F46 are the copolymers of tetrafluoroethene and hexafluoropropene, and the content of hexafluoropropene is about
15% or so, it is the modified material of polytetrafluoroethylene (PTFE).FEP had not only had characteristic similar with polytetrafluoroethylene (PTFE) but also had had thermoplasticity modeling
The excellent machinability of material.Thus it compensates for the deficiency of polytetrafluoroethylene (PTFE) processing difficulties, becomes instead of polytetrafluoroethylene (PTFE)
Material.FEP has excellent heat resistance, low frictional properties, non-stick and lubricity, chemical corrosion resistance, thermal stability and electricity
Insulating properties, in addition melt-processable, so having wide range of applications, being easy to make.FEP is widely used in electrical, electronics, chemical industry boat
The departments such as advanced science technologies and national defense industry such as the industrial departments such as sky, machinery and rocket-powered missile, peaceful boat.Suitable for fluoroplastics institute
Applicable every field, and can make and be difficult to process, complex-shaped product.Mechanical industry is used as sealing ring, instrument and meter
Components etc.；Electrical industry is used as electric wire insulation layer, cable cover(ing) etc.；Chemical industry is used as pump, valve, rectifying column, heat exchange
Equipment anticorrosion material and sealing material are made in device and its components, sealing element, atomic energy industry Central Region；Medically it is used as repairing heart
Valve and tiny tracheae.FEP can be used in big sun energy collector with light, good weatherability and high big positive energy transfer rate because of it
On.FEP has crystalline texture, and crystallinity 30%-55%, different from PIFE, the crystalline texture of FEP is special to condition of molding
Be it is less sensitive to cooling velocity, at processing temperatures, can get the square melt that really flows, will not generally be given birth in its cooling
At stomata, therefore it makes general pore-free.Perfluoroethylene-propylene (FEP) is by tetrafluoroethene (TFE) and hexafluoropropene (HFP)
It is copolymerized.
Copolyreaction control method: the strictly speaking factor of had an impact polymerization reaction such as temperature, pressure, polymerization
Medium, initiator type and quantity and mix monomer ratio etc. can be used as control of the means realization to polymerization process
System.FEP uses polymerization reaction in process of production, contains moisture and harmful components in the product, it is necessary to try to remove.
In process of production, material placement carries out polymerization reaction to existing FEP in the reaction vessel, and there are polymerization reactions not
Can sufficiently complete progress the problem of, expected requirement is not achieved so as to cause the quality of production of FEP, in production equal quality
When FEP, consumed raw material quality is larger, and consumption of raw materials is excessively high, high production cost, and the corrosion of the material in reaction process
Property it is stronger, reaction vessel is easily corroded and service life is caused to substantially reduce, simultaneously as FEP in process of production using polymerization
Reaction contains moisture and harmful components in the product, not high to the discharging control security of its product at present, does not remove adequately
Harmful components are gone to cause the discharging of FEP finished product materials inconvenient, discharging low efficiency is inconvenient to control, to the body of operator
Injury can be brought, safety is not high.
