Unyango loMphezulu lwePolytetrafluoroethylene (PTFE)

Njengomvelisi womthombo oqeqeshiweyo we-PTFE amalaphu aphezulu obushushu, i-Jiangsu Aokai New Materials iyakwazisa unyango olungaphezulu lwe-polytetrafluoroethylene (PTFE).

I-PTFE ineempawu ezibalaseleyo zokuxhathisa ubushushu obuphezulu kunye nobuphantsi, ukumelana nokugqwesa kweekhemikhali okugqwesileyo, i-coefficient ephantsi ye-friction kunye neempawu zokuzithambisa. Isetyenziswa ngokubanzi kwi-electronics, oomatshini, izixhobo zekhemikhali, i-aerospace, i-biomedicine kunye nezinye iindawo, ukufumana idumela 'loKumkani wePlastiki' . Nangona kunjalo, ngenxa ye-inertness yayo yeekhemikhali kunye namandla aphantsi komhlaba, i-PTFE inzima ukuyidibanisa nezinye izinto, ezinqanda usetyenziso lwayo kwinqanaba elithile. Ukuphucula ukunamathela phakathi kwe-PTFE kunye nezixhobo ezahlukeneyo, iindlela zidla ngokumkelwa ukuphucula umsebenzi womphezulu we-PTFE. Kwiimveliso ezahlukeneyo, i-Aokai New Materials isebenzisa ezi ndlela zilandelayo ze-PTFE zokuguqulwa komphezulu.

1. Unyango lweMichiza emanzi

Unyango lwemichiza ye-sodium-naphthalene  yenye yeendlela ezisebenzayo zokuguqulwa komphezulu we-PTFE. Ngenkqubo elula kunye neendleko eziphantsi, lukhetho olukhethwayo kwimveliso ebonakalayo kumzi-mveliso we-PTFE we-Aokai New Materials.

Unyango lwe-sodium-naphthalene ikakhulu lusebenzisa isisombululo se-etching ukusabela ngekhemikhali nge-PTFE, ukususa iiathom ezithile zefluorine kumphezulu. Oku kushiya umaleko we-carbonized kwaye kwazisa amaqela e-polar afana namaqela e-hydroxyl, amaqela e-carbonyl kunye ne-unsaturated bonds. La maqela e-polar anyusa amandla omhlaba wepolymer, anciphisa i-angle yoqhagamshelwano kunye nokuphucula ukumanzisa, ngoko ke ukuguqula i-PTFE isuka kwi-non-bondable ibe yi-bondable.

2. I-Mechanochemical Bonding Method

Xa iipolymers zixhomekeke kumandla angaphandle (umzekelo, ukutyunyuzwa, ukugawula, ukungqubuzana, njl.), i-macromolecular chain chain break kwaye iqhutywe kwi-chemical reactions, kuquka i-mechanodegradation, i-mechanochemical crosslinking, i-mechanochemical grafting, i-block copolymerization kunye ne-polymerization esebenzayo yoxinzelelo. Ezi zaziwa njengepolymer mechanochemical reactions.

Kwi-mechanochemical bonding, i-adhesive-coated polymer surface iyaxutywa. Ngokusebenzisa isenzo se-mechanochemical, i-polymer surface idlula i-mechanodegradation ukuze yenze i-macromolecular radicals yamahhala, ethi emva koko yenze i-covalent bonds kunye ne-adhesive molecules, idala i-interface eyomeleleyo yokudibanisa kunye nokuphucula kakhulu amandla okudibanisa okudibeneyo.

3. Indlela yokuNyibilika kobushushu obuphezulu

Umgaqo osisiseko wokuguqula umgangatho we-PTFE ngokusebenzisa ukunyibilika kobushushu obuphezulu kukuba: kubushushu obuphezulu, i-crystalline morphology yendawo ye-PTFE iyatshintshwa, kunye ne-high-surface-energy, izinto eziboshwe ngokulula ezifana ne-SiO₂ kunye ne-Al powder zifakwe. Emva kokupholisa, umaleko olungisiweyo oqulethe izinto ezibondayo zenza kumphezulu we-PTFE. Ekubeni iimolekyuli zezinto ezibophelelayo ziye zangena kumphezulu we-molecular layer ye-PTFE, ukuqhawula ibhondi kufuna ukutshatyalaliswa kwe-intermolecular, okukhokelela kumandla aphezulu okudibanisa.

4. Indlela yokusasazeka kwemitha

I-PTFE ifakwe kwiimonomers ezisebenzayo ze-polymerizable ezifana ne-styrene, i-fumaric acid, i-methacrylates kunye nezinye, emva koko i-irradiated ne- Co-60 . Oku kubangela i-polymerization yemichiza yee-monomers kumphezulu we-PTFE, yenze umaleko wepolymer ekulula ukuyidibanisa. Ukuxhunyelelwa kukwawenza rhabaxa umphezulu, kwandisa indawo yokudibanisa kunye nokwandisa amandla okudibanisa.

5. Iteknoloji yoNyango lwePlasma

Unyango lwe-Plasma yenye yezona teknoloji ziphuhla ngokukhawuleza kwi-PTFE ukuguqulwa komphezulu kwiminyaka yakutshanje.

Undoqo wobu buchwephesha kukubeka isampuli kwisixhobo sonyango lwe-plasma, apho ibhobho ye-ion okanye ukufakwa kwe-ion kuqhekeza amabhondi eemolekyuli okanye ukwazisa amaqela asebenzayo kumphezulu wepolymer, kusebenze umphezulu ukuze kufezekiswe ukuguqulwa. Iion inokuba yigesi engasebenziyo, iigesi ezisebenza ngemichiza okanye izinto zetsimbi. I-Bombardment ngeegesi ze-inert inokuguqula isakhiwo somphezulu wepolymer.

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