Qhov sib txawv tseem ceeb ntawm nitrile thiab Viton yog tias cov roj hmab nitrile muaj qhov sib piv qis thaum Viton muaj qhov sib piv loj.
Kev ntsuas qhov ceev yog ib txoj hauv kev zoo dua los paub qhov txawv ntawm nitrile roj hmab los ntawm cov khoom siv roj hmab Viton vim tias qhov ceev ntawm nitrile roj hmab feem ntau yog nyob ib ncig ntawm 1000 kg / m3 thaum qhov ceev ntawm Viton yog li 1800 kg / m3. Txawm li cas los xij, thaum xub thawj pom, peb tuaj yeem txheeb xyuas Viton los ntawm nws cov yam ntxwv ntsuab-xim av xim thiab nitrile roj hmab los ntawm nws cov xim daj.
Nitrile yog dab tsi?
Nitrile tebchaw yog cov organic tebchaw uas muaj cov tshuaj formula R-CN. Hauv lwm lo lus, cov tebchaw no muaj pawg cyano. Feem ntau, lo lus cyano- feem ntau yog siv sib hloov nrog lub sij hawm nitrile hauv kev lag luam. Peb tuaj yeem soj ntsuam ntau daim ntawv thov tseem ceeb ntawm nitrile tebchaw, suav nrog kev tsim cov methyl cyanoacrylate, kev tsim cov superglue, nitrile roj hmab, nitrile-muaj polymers uas muaj txiaj ntsig zoo hauv kev tsim cov hnab looj tes kho mob, thiab lwm yam. Muaj ntau lwm yam kev siv ntawm nitrile roj hmab ib yam nkaus.; tshwj xeeb tshaj yog raws li tsheb thiab lwm yam ntsaws ruaj ruaj vim nws tsis kam rau roj thiab roj. Qhov tseem ceeb tshaj, cov tshuaj inorganic uas muaj cov cyano pawg tsis yog hu ua nitrile compounds; lawv hu ua cyanide xwb.
Daim duab 01: Nitrile Roj Hmab Pob
Thaum xav txog cov qauv, nitriles yog linear molecules. Cov molecules no qhia txog sp hybridization ntawm cov pa roj carbon atom muaj triple daim ntawv cog lus nrog nitrogen atom. Nitrile compounds yog polar thiab muaj lub sijhawm dipole. Nitrile compounds tshwm sim ua kua uas muaj cov txheeb ze permittivities.
Peb tuaj yeem tsim cov nitrile compound ua lag luam ntawm ammoxidation thiab hydrocyanation. Ob txoj kev no muaj kev ruaj ntseg (ntsuab) thiab muaj qhov tso tawm yam tsawg kawg nkaus ntawm cov khoom phom sij.
Viton yog dab tsi?
Viton yog lub npe ntawm cov roj hmab hluavtaws thiab fluoropolymer elastomers. Lub npe Viton yog muab rau FKM compounds (fluorocarbon compounds). Cov ntaub ntawv polymer no muaj txiaj ntsig zoo hauv cov ntsaws ruaj ruaj, cov hnab looj tes tiv thaiv tshuaj, thiab lwm yam khoom pwm lossis extruded. Lub npe "Viton" yog lub npe lag luam ntawm Chemours Company txij li xyoo 1957.
Peb tuaj yeem faib Viton fluoroelastomers raws li kev tsim ntawm FKM, thiab pawg elastomers no suav nrog copolymer ntawm hexafluoropropylene (HFP), vinylidene fluoride (VDF) thiab perfluoromethylvinylether (PMVE). Peb tuaj yeem soj ntsuam tias cov ntsiab lus fluorine ntawm cov Viton polymers nyob ntawm 66-70%. Peb feem ntau tuaj yeem paub qhov txawv ntawm cov khoom no los ntawm feem ntau lwm cov ntaub ntawv polymer vim nws cov xim ntsuab-xim av. Txawm li cas los xij, ib qho kev ntsuam xyuas zoo dua yog txhawm rau txheeb xyuas qhov ntom ntawm cov khoom, uas feem ntau tshaj 1800 Kg / m3. Qhov ceev no yog siab dua li cov khoom siv roj hmab feem ntau.
Qhov txawv ntawm Nitrile thiab Viton yog dab tsi?
Nitrile roj hmab thiab Viton yog ob hom elastomer polymer uas txawv ntawm lawv cov tsos thiab ntom. Nitrile tebchaw yog cov organic tebchaw uas muaj cov tshuaj formula R-CN thaum Viton yog lub npe ntawm cov roj hmab hluavtaws thiab fluoropolymer elastomers. Kev ntsuas qhov ntom ntom yog ib txoj hauv kev zoo dua ntawm kev paub qhov txawv ntawm ob qho khoom siv polymer. Qhov sib txawv tseem ceeb ntawm nitrile thiab Viton yog tias cov roj hmab nitrile muaj qhov sib piv qis dua thaum Viton muaj qhov sib piv loj.
Hauv qab infographic teev ntau qhov sib txawv ntawm nitrile thiab Viton.
Summary – Nitrile vs Viton
Qhov sib txawv tseem ceeb ntawm nitrile thiab Viton yog tias cov roj hmab nitrile muaj qhov sib piv qis thaum Viton muaj qhov sib piv loj. Txawm li cas los xij, los ntawm kev saib cov khoom, peb tuaj yeem txheeb xyuas Viton los ntawm nws cov tsos ntawm cov xim ntsuab-xim av uas cov roj hmab nitrile muaj xim daj.
