PERFLUOROELASTOMERS
Iiperfluoroelastomers (FFKM) zenziwa ikakhulu ukusuka kwi-tetrafluoroethylene, perfluoromethyl vinyl ether, kunye ne-vulcanization point monomers, kwaye inokumelana okugqwesileyo kwimichiza, ubushushu, i-extrusion, kunye ne-deformation yoxinzelelo lobushushu obuphezulu.Ngaphandle kwezinyibilikisi ezithile eziphezulu ze-fluorocarbon, azichatshazelwa nakweyiphi na indlela, kubandakanywa ii-ethers, ii-ketones, i-esters, i-amides, i-nitriles, i-oxidizing agents, amafutha, i-acids, i-alkali, njl. iipropati.

Usetyenziso oluphambili
1.Le mveliso yi-triazine vulcanized perfluoroelastomer, esetyenziswa kumaqondo obushushu ukusuka kwi-275℃ ukuya kwi-300℃.Ingasetyenziswa ixeshana elifutshane kubushushu obuphezulu ukuya kuma 315℃.Iiperfluoroelastomers zisetyenziswa njengetywina lerabha kunye nemveliso ekwaziyo ukumelana nobushushu obuphezulu.imithombo yeendaba ezonakalisayo, kwaye uninzi lwezinyibilikisi, ezifana ne-diaphragms, imisesane yokutywina, imisesane yokutywina emise okwe-V, i-O-rings, ipackers, iibhola eziqinileyo, iigaskets,sheaths, iikomityi, imibhobho, kunye neevalvu.
2.Ikakhulu isetyenziswa kwi-aviation, i-aerospace, imboni yeekhemikhali, i-petroleum.atomic energy, i-semiconductor kunye nezinye iifelds.
Isicelo
1.Xa iiperfluoroelastomers ekrwada zidibana nomlilo, ziya kukhupha ityhefu yehydrogen fluoride kunye ne-fluorocarbon organic compound.
I-2.I-Perfluoroelastomers ayinakuxutywa kunye nomgubo wesinyithi onjenge-aluminium kunye ne-magnesium powder, okanye ngaphezulu kwe-10% ye-amine compound, ukuba oko kuyenzeka, ubushushu buya kuvela kwaye izinto ezininzi ziya kusabela nge-perfluoroelastomers, eziya konakalisa izixhobo kunye nabaqhubi.
Ukupakishwa, uThutho kunye noGcino
I-1.Perfluoroelastomers zipakishwe kwiingxowa zeplastiki ze-PE kwaye zifakwe kwiibhokisi zekhadibhodi.Ubunzima beNet yi-20Kg kwibhokisi nganye.
2.IiPerfluoroelastomers zithuthwa ngokwemichiza engeyongozi.3.IiPerfluoroelastomers zigcinwa kwindawo yokugcina impahla, eyomileyo nepholileyo, kwaye kufuneka zigcine kude nomthombo wongcoliseko, ukukhanya kwelanga kunye namanzi ngexesha lokuhamba.
