Nhanganyaya
Munzvimbo yeindasitiri yemazuva ano, zvigadzirwa zverabha zvave zvakakosha nekuda kweakasarudzika hunhu senge elasticity, kupfeka kuramba, uye makemikari kuramba. Pakati peiyi, fluorine rubber (FKM) uye perfluoroether rubber (FFKM) inomira semhando yepamusoro-soro, inozivikanwa nepamusoro-soro yemakemikari uye yakakwirira-yekudzivirira. Iyi ongororo yakazara inoongorora mutsauko, mashandisirwo, mutengo, mafomu, uye zvivakwa zveFKM neFFKM, nechinangwa chekupa ruzivo rwakakosha kune vanobatana mumaindasitiri ane hukama.
Misiyano Yakakosha Pakati peFluorine Rubber (FKM) uye Perfluoroether Rubber (FFKM)
Mushonga Wemakemikari
Musiyano wekutanga pakati peFKM neFFKM uri mune yavo makemikari zvimiro. FKM ichidimbu chepolymer ine kabhoni-kabhoni bond (CC) mucheni yayo huru, nepo FFKM iri yakazara fluorinated polymer ine kabhoni-oxygen-carbon (COC) chimiro, chakabatana nemaatomu eokisijeni (O). Uku kusiyanisa kwechimiro赋予FFKM yepamusoro kemikari uye yakakwirira-tembiricha kuramba kana ichienzaniswa neFKM.
Chemical Resistance
FFKM's main cheni, isina kabhoni-kabhoni mabhondi, inopa yakawedzera kuramba kumakemikari media. Sezvinoratidzwa mumufananidzo unofambidzana, simba rebhondi re carbon-hydrogen bonds ndiro rakaderera (inenge 335 kJ / mol), iyo inogona kuita kuti FKM isanyanya kushanda mumagetsi ane simba uye polar solvents kana ichienzaniswa neFFKM. FFKM inoshingirira kune angangoita ese anozivikanwa makemikari media, anosanganisira akasimba asidhi, mabhesi, organic solvents, uye oxidants.
High-Temperature Resistance
FFKM zvakare inokunda mukupikisa kwepamusoro-tembiricha. Nepo tembiricha yeFKM inoramba ichishanda kazhinji inotangira pa200-250°C, FFKM inogona kumira tembiricha kusvika pa260-300°C. Uku kugadzikana kwepamusoro-tembiricha kunoita kuti FFKM inyanyokodzera kunyorera munzvimbo dzakanyanyisa.
Minda Yekushandisa
Fluorine Rubber (FKM)
FKM inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana nekuda kwekunaka kwayo kwemakemikari kuramba uye nepakati-yepamusoro-tembiricha kuramba:
- Indasitiri Yemotokari: FKM inoshandiswa mukugadzira zvisimbiso, zvisimbiso zvemafuta, O-mhete, nezvimwe, kunyanya muinjini uye masisitimu ekufambisa.
- Kemikari Indasitiri: FKM inoshandiswa zvisimbiso mumapombi, mavharuvhu, pombi, uye zvimwe midziyo kudzivirira kubuda kwemakemikari media.
- Indasitiri yeMagetsi: Inoshandiswa kusungirira zvidimbu mumawaya netambo, kunyanya munzvimbo dzinopisa uye dzinoparadza makemikari.
Perfluoroether Rubber (FFKM)
FFKM inoshandiswa muminda inoda yakanakisa makemikari uye yakakwirira-tembiricha kuramba:
- Aerospace: FFKM inoshandiswa zvisimbiso mundege uye spacecraft kutsungirira kupisa kwakanyanya uye makemikari nharaunda.
- Semiconductor Indasitiri: Inoshandiswa zvisimbiso mune semiconductor kugadzira michina kudzivirira kemikari gasi kubuda.
- Petrochemical Indasitiri: FFKM inoshandiswa zvisimbiso mune yakakwirira-tembiricha uye yakakwirira-kudzvanywa michina mumafuta ekunatsa uye zvidyarwa zvemakemikari.
Mutengo uye Mutengo
FFKM inodhura yekugadzira yakakwira inokonzeresa mutengo wemusika wakakwira zvichienzaniswa neFKM. Kuoma kwezvinhu zveFFKM zvekushandisa uye maitiro ekugadzira anokwidza mutengo wayo. Nekudaro, nekupihwa kuita kwakanaka kweFFKM munzvimbo dzakanyanyisa, mutengo wayo wepamusoro unotenderwa mune mamwe maapplication.
Fomu uye Kugadziriswa
Fluorine Rubber (FKM)
FKM inowanzo kupihwa seyakasimba rabha, musanganiswa rabha, kana preformed zvikamu. Maitiro ayo ekugadzirisa anosanganisira compression molding, extrusion, uye jekiseni kuumba. FKM inoda michina yakasarudzika uye maparamita ekuita nekuda kwekushisa kwayo kwepamusoro.
Perfluoroether Rubber (FFKM)
FFKM inopihwa zvakare muchimiro cherabha rakasimba, rabha rakasanganiswa, kana zvikamu zvakafanorongwa. Kudzivirirwa kwayo kwepamusoro-tembiricha kunoda tembiricha yepamusoro yekugadzirisa uye zvakanyanya kuomesera michina uye zvinodiwa maitiro.
Kuenzanisa Kwekuita
Chemical Resistance
FFKM yemakemikari kuramba iri nani zvakanyanya pane yeFKM. FFKM inoshingirira kune angangoita ese anozivikanwa makemikari media, anosanganisira akasimba asidhi, mabhesi, organic solvents, uye oxidants. Kunyangwe FKM ichipawo yakanaka makemikari kuramba, hainyanyi kushanda mune mamwe akasimba oxidants uye polar solvents zvichienzaniswa neFFKM.
High-Temperature Resistance
FFKM's high-temperature kuramba iri pamusoro peFKM's. FKM inoramba ichishanda tembiricha inowanzoita 200-250 ° C, nepo FFKM inogona kusvika 260-300 ° C. Uku kugadzikana kwepamusoro-tembiricha kunoita kuti FFKM iwedzere kushanda munzvimbo dzakanyanyisa.
Mechanical Performance
Ose ari maviri FKM neFFKM ane akanakisa emuchina zvivakwa, anosanganisira yakakwirira elasticity, kupfeka kuramba, uye kubvarura kuramba. Nekudaro, FFKM's mechanic properties inogadzikana zvakanyanya pakupisa kwepamusoro, zvichiita kuti ive yakavimbika mukupisa-kupisa kwekushandisa.
Market Prospects
Nekuenderera mberi kwekufambira mberi kwehunyanzvi hwemaindasitiri, kudiwa kwezvinhu zverabha zvepamusoro-soro kuri kuwedzera. FKM neFFKM vane tarisiro yakakura yekushandisa munzvimbo dzakasiyana siyana nekuda kwekuita kwavo kwakanaka:
- Indasitiri yeMotokari: Kuvandudzwa kwemotokari dzemagetsi matsva kuri kuwedzera kudiwa kwezvisimbiso zvinodzivirira kudziya kwepamusoro uye makemikari asingadziviriri, zvichiwedzera kuwedzera kushandiswa kweFKM neFFKM.
- Indasitiri yeKemikari: Kusiyanisa uye kuomarara kwezvigadzirwa zvemakemikari kuri kuwedzera kudiwa kwemakemikari anopikisa zvisimbiso, zvichiwedzera kuwedzera kushandiswa kweFKM neFFKM.
- Indasitiri yeMagetsi: Iyo miniaturization uye kushanda kwepamusoro kwemidziyo yemagetsi iri kuwedzera kudiwa kwemidziyo yekuisa insulating isingaenderane nekupisa kwakanyanya uye kemikari corrosion, ichiwedzera kuwedzera kushandiswa kweFKM neFFKM.
Mhedziso
Fluorine rabha (FKM) uye perfluoroether rubber (FFKM), sevamiriri vepamusoro-soro rubber, vane tarisiro yakafara yekushandiswa muminda yakasiyana-siyana nekuda kwekunaka kwavo kwemakemikari kuramba uye kupisa kwepamusoro. Kunyangwe FFKM ichidhura, kuita kwayo kwakanyanya munzvimbo dzakanyanyisa kunopa mukana usingadzoreki mune mamwe maapplication. Nekuenderera mberi kwekufambira mberi kwehunyanzvi hwemaindasitiri, kudiwa kwezvinhu zverubha zvemhando yepamusoro kucharamba kuchiwedzera, uye tarisiro yemusika yeFKM neFFKM yakakura.
