Isiqulatho seFluorine ePhezulu yeFKM (70%)
I-Fluoroelastomer FKM Terpolymer Gum-246 series are terpolymer of vinylidenefluoride,tetrafluoroethylene and hexafluoropropylene.Ngenxa yomxholo wayo ophezulu wefluorine,irabha etshikisiweyo inepropathi egqwesileyo ye-oyile kunye nokuzinza okuphezulu kwe-thermal. ixesha elide, kwi-320 ℃ ixesha elifutshane.Ipropati ye-oyile ye-antil kunye ne-asidi ye-anti ingcono kune-FKM-26, ukuchasana kwe-FKM246 kwi-oyile, i-ozone, i-radiation, umbane kunye ne-flamer ifana ne-FKM26.

Ukusetyenziswa kweMveliso
I-FKM246 isetyenziswa kakhulu kwiimoto, koomatshini, kwi-petrochemical, nakwamanye amasimi. Umzekelo, izinto zokutywina ezimile/eziguqukayo zenqwelo-moya zenkqubo yolwelo kunye nenkqubo yokuthambisa; esetyenziswa kwizixhobo zokomba kunye nemibhobho yeoli; ishishini lemichiza lezixhobo, uqhagamshelo lwemibhobho eguquguqukayo, intambo yempompo okanye imathiriyeli yokutywina ekwaziyo ukutyiwa, eyenziwe ngemibhobho yokuthwala izinyibilikisi okanye ezinye izinto zosasazo, ezinjengomhlwa.
Ingqalelo
Irabha ye-1.Fluoroelastomer terpolymer inozinzo olulungileyo lobushushu phantsi kwe-200℃.Iyakuvelisa ukubola komkhondo ukuba ibekwe kwi-200-300'C ixesha elide, kwaye isantya sayo sokubola sinyuka ngaphezu kwe-320 ℃, iimveliso zokubola ziyityhefu ye-hydrogen fluoride. kunye ne-fluorocarbon organic compound.Xa irabha ekrwada enombane idibana nomlilo, iya kukhupha ityhefu yehydrogen fluoride kunye ne-fluorocarbon organic ikhompawundi.
I-2.FKM ayinakuxutywa kunye ne-powder yensimbi efana ne-aluminium powder kunye ne-magnesium powder, okanye ngaphezulu kwe-10% ye-amine compound, ukuba oko kwenzeka, ukushisa kuya kuvela kwaye izinto ezininzi ziya kusabela nge-FKM, eziza konakalisa izixhobo kunye nabaqhubi.
Ukupakishwa, uThutho kunye noGcino
I-1.FKM ipakishwe kwiingxowa zeplastiki ze-PE, kwaye emva koko ilayishwe kwiibhokisi, ubunzima be-net yebhokisi nganye yi-20kg.
I-2.FKM igcinwe kwindawo yokugcina izinto ecocekileyo, eyomileyo nepholileyo.Ithuthwa ngokwemichiza engeyongozi, kwaye kufuneka igcine kude nomthombo wongcoliseko, ilanga kunye namanzi ngexesha lokuhamba.
