Iifluoropolymers zorhwebo zisekelwe kwi-TFE, VDF, kunye ne-CTFE encinci.Imizekelo ye-comonomers ibandakanya i-PMVE, i-PEVE, i-PPVE, i-HFP, i-CTFE, kunye ne-PFBE.Iziphumo eziqhelekileyo zokutshintshwa kwe-fluorine ye-hydrogen kwi-polymer eyongeziweyo ibandakanya ukunyuka kweekhemikhali kunye nokuxhathisa ukunyibilika, ukuphuculwa kwezinto zombane ezifana ne-dielectric ephantsi, i-coefficient ephantsi ye-friction, indawo ephezulu yokunyibilika, ukunyuka kwefoto kunye nokuzinza kwe-thermal, ukuphucula ukuxhathisa idangatye, kunye nokunciphisa amandla omatshini. iipropati.Iipropati zokugqibela zifezekiswa xa i-polymer ifakwe ngokupheleleyo.
Ubuchule bokwenza
Ngaphandle kwee-fluoropolymers ezimbini, i-PVF kunye ne-PTFE, ezinye ii-resin ezichazwe kwesi sahluko zinokucutshungulwa ngeendlela eziqhelekileyo zokunyibilika kwe-melt njenge-injection, ukudluliselwa kunye nokuvuthela ukubumba, ukukhupha kunye nokubunjwa okujikelezayo.Izixhobo zenkqubo ye-fluoropolymers kufuneka zenziwe kwi-alloys-resistant corrosion ngenxa ye-corrosion compound enokuthi iveliswe xa i-fluoropolymers ishushu ngaphezu kweendawo zabo zokunyibilika.I-viscosity ephezulu yokunyibilika kwezi resins inokufuna umgubo ongaphezulu kunye nezixhobo zokulinganisa uxinzelelo oluphezulu.
I-PTFE icutshungulwa kusetyenziswa iindlela zesinyithi-zokwenziwa komgubo apho i-preform ibunjwa kwaye "i-sintered."Ukubumba ucinezelo kunokusetyenziselwa ukwenza iinxalenye ze-PTFE.PTFE dispersions zisetyenziswa ngobuchule efanayo kwezinye iingubo.Cola i-extrusion apho i-PTFE idityaniswe ne-hydrocarbon, phambi kokubumba i-preform, isetyenziselwa ukuqhubeka nokwenza i-PTFE kwiityhubhu, iiteyiphu, kunye nokugquma ucingo.I-hydrocarbon ifakwe umphunga phambi kokuba inxalenye itshiswe.
I-PVF ihlakazwe kwi-polar latent solvent efana ne-dimethyl acetamide kwaye i-melt-extruded njenge-plastisol, ilandelwa ukususwa kwe-solvent ngokumisa.
Usetyenziso
Iipropati ze-fluoropolymers eziye zakhokelela kwizicelo ziquka ukuchasana kweekhemikhali, ukuzinza kwe-thermal, iipropati ze-cryogenic, i-coefficient ephantsi ye-friction, amandla aphantsi komhlaba, i-dielectric ephantsi, umthamo ophezulu kunye nokumelana nomlilo, kunye nokumelana nomlilo.IiFluoropolymers zisetyenziswa njenge-liners (process surface) ngenxa yokumelana nokuhlaselwa kweekhemikhali.Babonelela ngolondolozo oluhlala ixesha elide, oluphantsi, kunye nezinye iindlela zoqoqosho kwiintsimbi ezingaqhelekanga ukuze zisetyenziswe kumaqondo obushushu aphezulu ngaphandle kokwazisa ukungcola.Iipropati zombane zenza ukuba ii-fluoropolymers zixabiseke kakhulu kwi-electronics kunye ne-electrical applications njenge-insulators, umzekelo, i-FEP kunxibelelwano lwedatha.
Kwizixhobo zemoto kunye neofisi, iipropathi zomatshini ze-fluoropolymers zinenzuzo kwiibheringi eziphantsi kwe-friction kunye nezitywina ezichasene nokuhlaselwa kwee-hydrocarbons kunye nezinye izinto ezimanzi.Ekuqhubekeni kokutya, uLawulo lokuTya kunye neDrugs oluvunyiweyo lwe-fluoropolymer zizinto zokwenziwa kwezixhobo ngenxa yokuchasana kwazo neoyile kunye nezinto zokucoca, kunye neempawu zabo zokuchasa intonga kunye ne-friction ephantsi.Kwi-houseware, ii-fluoropolymers zisetyenziswa njengezinto zokugquma ezingakhuni kwizinto zokupheka kunye nezixhobo zombane.Amanqaku ezonyango afana neepetshi zotyando kunye nokuxhunyelelwa kwentliziyo kuxhomekeke kuzinzo lwexesha elide lweefluoropolymers kwakunye namandla azo aphantsi komhlaba kunye nokumelana neekhemikhali.
Kwizikhululo zeenqwelo moya, amabala emidlalo, kunye nezinye izakhiwo, ilaphu legilasi lefiber egqunywe nge-PTFE lenziwe lafulelwa kunye neendawo ezivalekileyo.I-PTFE ibonelela ngokugqwesileyo kokuxhathisa kwimozulu, kubandakanywa ukuvezwa kwimitha ye-UV ekukhanyeni kwelanga, ukuxhathisa idangatye lokhuseleko, kunye namandla aphantsi omhlaba wokuxhathisa umhlaba, kunye nokucoca lula.
