PTFE Unyango lwePlasma Hydrophilic lwePowder
PTFE powder isetyenziswa ngokubanzi njengesongezo kwiingubo ezahlukeneyo ezisekwe kwi-solvent-based kunye neengubo zomgubo, ezifana neengubo zeplastiki, iipeyinti zokhuni, iingubo ze-coil, ii-UV zokunyanga iipeyinti, kunye neepeyinti, ukuphucula ukusebenza kwazo kokukhutshwa komngundo, ukuxhathisa ukukrala komphezulu, ukuthambisa, ukuxhathisa imichiza, ukumelana nemozulu, kunye nokuthintela amanzi. PTFE ii-micro-powders zingasetyenziswa njengesithambiso esiqinileyo endaweni yezithambisi ezingamanzi. Zingasetyenziselwa ukuphucula ukuhamba kwe-inki kunye ne-anti-wear agent, kunye nenani eliqhelekileyo lokongezwa kwe-1-3wt%. Zingaphinda zisetyenziswe kwizinto zokugquma ezinganamatheli kwi-cookware, kunye nesixa esiqhelekileyo sokongeza esingekho ngaphezulu kwe-5wt%. I-Organic solvent dispersion ingasetyenziswa njenge-arhente yokukhulula. Zingaphinda zisetyenziswe njengeejenti ezichasene ne-drip ezisebenzayo kwiiplastiki ezahlukeneyo, ezifana ne-ABS, i-polycarbonate (i-PC), i-polyurethane (i-PU), kunye ne-polystyrene (PS).
PTFE yi-polymer ecwebe kakhulu eyenziwe kwi-tetrafluoroethylene monomers, ene-insulation egqwesileyo yombane, ukuxinezeleka okuphantsi komhlaba kunye ne-friction coefficient, ukungatsha, ukuchasana nokuguga kwe-atmospheric, ukuguquguquka okuphezulu kunye nobushushu obuphantsi, kunye neempawu eziphezulu zomatshini.
Nangona kunjalo, ngenxa yesakhiwo sayo esilingeneyo kunye ne-non-polar, ukungabikho kwamaqela asebenzayo, kunye ne-crystallinity ephezulu, PTFE yimathiriyeli engeyiyo i-polar ene-hydrophobicity eyomeleleyo, ukunganyaniseki kweekhemikhali, amandla aphantsi komhlaba, kunye nokumanzisa okubi kunye nokunamathela kwezinye izinto, ezithintela kakhulu ukusetyenziswa kwayo. Ngoko ke, ukwandisa ukusetyenziswa kwe PTFE, umphezulu wayo kufuneka uphathwe ukwandisa amandla ayo angaphezulu kunye nokuphucula i-hydrophilicity yayo.
Unyango lwePlasma yenye yetekhnoloji ephuhlayo ngokukhawuleza PTFE ukuguqulwa komphezulu kwiminyaka yakutshanje. Umgaqo wokuguqulwa kweplasma kukusebenzisa ibhombu ye-ion okanye inaliti kumphezulu wepolymer ukuvelisa iibhondi ezaphukileyo okanye ukwazisa amaqela asebenzayo, ngaloo ndlela kusebenze umphezulu wokuphucula ukunamathela komphezulu wezinto. Iigesi eziqhelekileyo ezisetyenziswayo ziquka i-oxygen, i-hydrogen, i-nitrogen, i-carbon tetrafluoride, kunye ne-argon. Ibhombu ye-plasma yegesi ye-inert inokutshintsha isakhiwo somphezulu we-copolymer.
I-Plasma iqulethe amasuntswana asebenzayo afana nee-electron, i-ion, kunye neeradicals zamahhala. Ukuguqulwa komphezulu weplasma kubandakanya ukuguqulwa komzimba kunye neekhemikhali. Ukuguqulwa komzimba kukubhobhoza kwee-electron kunye nee-ion kumphezulu wepolymer, oqhawula amaqhina ekhemikhali ekhonkco lepolymer, kubangela ukuthotywa komgangatho, kwaye zenze iimveliso zokonakala ezidipozithi kumphezulu wepolymer. Ukuguqulwa kwemichiza kubandakanya ukwazisa amaqela asebenzayo ngokusebenzisa i-radicals yamahhala esabelayo kunye ne-polymer surface, ukutshintsha ukubunjwa kweekhemikhali komhlaba. Zombini ukuguqulwa komzimba kunye neekhemikhali kuya kubangela utshintsho kwiimpawu zomhlaba. Ngethuba lokunyangwa kwe-plasma, ukungeniswa kwamaqela asebenzayo kunye neempendulo zokuthotywa azikwazi ukuhlukana kodwa zenzeke ngexesha elinye, kwaye ukuthotywa kokuthotywa akuphepheki. Isitshixo sokuguqulwa okusebenzayo komphezulu kukunciphisa ukusabela kokuthotywa kunye nokwandisa indima yentshayelelo yeqela elisebenzayo.
The PTFE ukuguqulwa komgubo usebenzisa umatshini wokucoca iplasma engumgubo. I-Plasma isebenza kwipowder ukuze itshintshe ngenjongo iimpawu zayo zomzimba kunye neekhemikhali, ngelixa igcina iipropati zokuqala zomgubo, ukuyinika iipropati ezintsha zomphezulu, iguqula iipropati zayo zomphezulu ukusuka kwi-hydrophobic ukuya kwi-hydrophilic okanye ngokuchaseneyo, ngaloo ndlela iphucula ukumanzi kwamasuntswana omgubo kwaye ukuphucula ukunamathela kwamasuntswana omgubo phakathi.
