Uthini uMmiselo wokuSebenza weTeflon's Non-Stick Surface?

I-Jiangsu Aokai New Materials, umenzi womthombo weTeflon high-temperature cloth, ichaza isayensi emva kwayo.Ipropathi egqwesileyo ye-non-stick yeTeflon (igama lekhemikhali: Polytetrafluoroethylene, PTFE) livela ikakhulu kwimigaqo emibini engundoqo: amandla aphantsi komhlaba  kunye nesakhiwo sawo esisodwa se-molecular..

1. Amandla oMphezulu aphantsi kakhulu

Lo ngumgaqo osisiseko wephysicochemical of non-stick performance.Amandla angaphezulu amisela ukuba kulula kangakanani na umphezulu oqinileyo ukumanziswa lulwelo.

I-Teflon inamandla aphantsi kakhulu (malunga ne- 18.5 mN / m ), ephantsi kakhulu kunezincamathelisi eziqhelekileyo, i-oyile, okanye amanzi (uxinzelelo lwamanzi angaphezulu malunga ne-72 mN / m).

Ngokutsho kwethiyori yokumanzisa , ulwelo lunokusasazeka kuphela kumphezulu oqinileyo ukuba ukucinezeleka kwawo kumphezulu kungaphantsi kumandla omhlaba oqinileyo. Ekubeni uxinzelelo lomphezulu lwezinto ezininzi luphezulu kunolo lweTeflon, azikwazi ukumanzisa umphezulu walo. Endaweni yoko, zifinyela zibe ngamathontsi (njengamanzi akwigqabi lelotus) aneengile yokudibana ephezulu kakhulu (ngokuqhelekileyo> 90°, nokuba kufutshane ne-120°).

Isiphumo : Eyona ndawo yoqhagamshelwano phakathi kwento encamathelayo kunye neTeflon incinci kakhulu, ngoko ke akukho sixhobo se-ankile esisebenzayo okanye ukudityaniswa kweekhemikhali kunokwenzeka. Izingcolisi ke ngoko ziyatyibilika okanye zicinywe lula.

2. Iibhondi ezomeleleyo ze-C-F kunye neSakhiwo se-Molecular engekho-Polar

Ulwakhiwo lwemolekyuli yeTeflon iqulathe umqolo wekhabhoni ongqongwe ngokuqinileyo ziiathom zefluorine.

·  Amandla ebhondi ephezulu : Ibhondi ye-carbon–fluorine (C–F) yenye yezona qhina zinamandla kwi-organic chemistry. Oku kwenza iTeflon izinze kakhulu ngokwekhemikhali kwaye iphantse ibe inert phantse kuzo zonke izinto (ngaphandle kwesinyithi esinyibilikisiweyo sealkali kunye neearhente ezimbalwa ezomeleleyo zokuthambisa). Ayenzi imibhobho yeekhemikhali (i-covalent okanye i-hydrogen bonds eyomeleleyo) ngezinto ezincamathelayo.

·  I-Polarity ephantsi : Nangona i-fluorine ine-electronegative ephezulu, ulungiselelo lwayo olulingeneyo ecaleni kwetsheyini yemolekyuli iyacima umzuzu we-dipole. I-Teflon i-non-polar ngamandla, i-hydrophobic, kunye ne-oleophobic.Amanzi (i-polar) kunye ne-oyile (i-non-polar kodwa i-high surface tension) ayikwazi ukwenza imikhosi ebalulekileyo ye-intermolecular (i-weak van der Waals forces) kunye neTeflon.

3. I-Synergy phakathi kwe-Low Friction Coefficient kunye ne-Non-Stick Performance

Nangona i-coefficient ephantsi yokukhuhlana ichaza ubukhulu becala ukutyibilika okuqinileyo, kuhambelana nokuziphatha okungabambekiyo.

I-Teflon inomnye weyona milinganiso iphantsi ye-friction phakathi kwazo zonke izinto eziqinileyo (ezijikeleze 0.04).

Xa izinto ezincangathi zizama ukubambelela, ukukhuhlana okuphantsi kakhulu kuzithintela 'ekubambiseni' umphezulu. Nangona ukunamathela obuthathaka, amandla amancinci angaphandle okanye ubunzima bubangela ukuba izinto eziphathekayo zityibilike kwaye ziqhawule ngokulula.

Olu lwazi lungasentla lunikezelwe nguJiangsu Aokai New Materials Technology Co., Ltd.
