Intshayelelo
Hexafluorobutyl methacrylate. Oku kulandelayo kukwaziswa okuneenkcukacha kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-hexafluorobutyl methacrylate:
Umgangatho:
1. Imbonakalo: ulwelo olungenambala.
3. Ubuninzi: 1.35 g/cm³.
4. I-Solubility: i-soluble kwi-solvents ye-organic, njenge-methanol, i-ethanol, i-ether kunye ne-methylene chloride, i-insoluble emanzini.
Sebenzisa:
1. Njenge-surfactant: I-Hexafluorobutyl methacrylate ingasetyenziselwa ukulungiswa kwee-surfactants, kwaye isoloko isetyenziselwa ukuhlanganiswa kwee-coatings kunye neenki ezinamandla aphezulu aphezulu.
2. Ukulungiswa kweepolymers ezikhethekileyo: I-Hexafluorobutyl methacrylate ingasetyenziselwa i-monomer yeepolymers ezikhethekileyo ukulungiselela izinto ezineempawu ezikhethekileyo, ezifana nokumelana nokushisa okuphezulu, ukuchasana nokubola kweekhemikhali, njl.
Indlela:
I-Hexafluorobutyl methacrylate ingalungiswa nge-hydrofluoric acid-catalyzed gas-phase fluorination. Inyathelo elithile kukuxuba umphunga we-hexafluorobutyl acrylate kunye nomphunga we-methanol, kwaye uhambe nge-hydrofluoric acid catalytic reaction ukuvelisa i-hexafluorobutyl methacrylate.
Ulwazi ngoKhuseleko:
1. I-Hexafluorobutyl methacrylate iyacaphukisa kwaye inokubangela ukucaphuka, ukutshisa kunye nokunye ukuphazamiseka xa udibana nolusu, amehlo okanye umgudu wokuphefumula. Kufuneka kunxitywe izixhobo ezifanelekileyo zokukhusela xa zisetyenziswa.
2. I-Hexafluorobutyl methacrylate inokutsha, gwema ukudibanisa nomlilo ovulekileyo okanye ukushisa okuphezulu.
3. Xa usebenzisa okanye ugcina, kuphephe ukudibana nezinto ezinjengee-oxidants, ii-asidi ezinamandla okanye iialkali ezinamandla ukuphepha ukusabela okuyingozi.
4. Ukulahlwa kwenkunkuma kufuneka kuhambelane nemithetho nemigaqo yendalo esingqongileyo, kwaye akufuneki kukhutshelwe ngokuthanda kwakhe.
