Iimpembelelo eziphambili ze-PTFE Emulsion Ubungakanani boSasazo kunye nobunzima beMolekyuli kwi-Wear Resistance yeGlasi yeFayibha ilaphu

Ilaphu leTeflon elinobushushu obuphezulu obuvela kwiJiangsu Aokai New Materials yimathiriyeli ehlanganisiweyo esekwe kwilaphu lefiber yeglasi, efakwe kwi-polytetrafluoroethylene (PTFE) emulsion kunye ne-sintered. Ukumelana kwayo nokunxiba okugqwesileyo kubalulekile ekuqinisekiseni ubomi benkonzo ende phantsi kweemeko zokusebenza ezinamandla ezinje ngamabhanti okuhambisa, iigaskets zokukhulula, kunye nokomisa i-microwave. Imiba ephambili emisela ukunyanzeliswa kokunxiba kwelaphu leTeflon lobushushu obuphezulu lala kwizalathisi ezibini ze-emulsion ye-PTFE yokumitha: ubungakanani besuntswana lokusabalalisa  kunye nobunzima bemolekyuli . Ezi zinto zimbini zichaza ngokuthe ngqo ukunyaniseka, ukufana kunye nokuqina komgangatho okhuselayo wengubo yeTeflon ephezulu yokushisa. Ukwandisa inkqubo yokuveliswa kwengubo yeTeflon ephezulu yokushisa, kubalulekile ukuqonda iziphumo zabo eziphambili ekuxhathiseni ukunxiba.

Ubungakanani kunye nokuhanjiswa kwamasuntswana e-emulsion kuqinisekisa ukuba i-PTFE inokungena ngokufanayo kwaye ibambelele ngokuqinileyo kwisakhelo sefiber yeglasi yelaphu leTeflon lobushushu obuphezulu.

Uluhlu lwesayizi lwamasuntswana olufanelekileyo lwelaphu leTeflon lobushushu obuphezulu :I-emulsions ye-PTFE eyenzelwe ngokukodwa ukufakwa kwelaphu le-Teflon lobushushu obuphezulu bukholisa ukuba nobungakanani besuntswana eliqhelekileyo elilawulwa kwi -0.15–0.35 µm (150–350 nm) . Umzekelo, i-emulsions ekhethekileyo ye-Teflon yobushushu obuphezulu belaphu njenge-Chemours DISP 30LX inomlinganiselo we-particle ye-0.22 µm. Amacandelo alolu luhlu anokungena ngokufanelekileyo kwii-fiber bundles ze-Teflon high-temperature cloth, ezenza i-anchored eqinile kunye ne-smooth layer yokukhusela emva kokucoca.

Iziphumo ezibi zobungakanani bamasuntswana amancinci kakhulu : I-emulsion ecolekileyo kakhulu inokungena ngokugqithisileyo. Ngexesha lokukhulelwa, kudla ngokungena ngokugqithisileyo kumqolo okanye i-voids yangaphakathi ye-substrate, ukunciphisa izixhobo ezisebenzayo zokunxiba ezigcinwe kumphezulu we-Teflon-high-temperature cloth kunye nokunciphisa ubomi bokugqoka ubuso.

Iziphumo ezibi zobungakanani bamasuntswana amakhulu ngokugqithisileyo :I-emulsion erhabaxa ngokugqithisileyo ayinakungena nzulu kwizikhewu zefiber yeglasi yelaphu lobushushu obuphezulu beTeflon, yenze kuphela isambatho esingaphezulu esingaphezulu. Xa ilaphu leTeflon elinobushushu obuphezulu liphantsi kokukhuhlana okuguquguqukayo, le ngubo ingabambekanga kakuhle ixobuka ngokulula ibe ngamaqhekeza amakhulu, ikhokelela ngokuthe ngqo kukusilela kwemveliso.

Ubunzima bemolekyuli bumisela iimpawu zoomatshini kunye nokuziphatha kwe-tribological yepolymer ye-PTFE ngokwayo, kwaye ibalulekile kwindlela yokuchasa ukunxitywa kwelaphu leTeflon lobushushu obuphezulu.

Indlela yokunganxibi kunye neyokuzithambisa yelaphu leTeflon lobushushu obuphezulu :Ukumelana nokunxitywa kwelaphu leTeflon lobushushu obuphezulu liphuma kwi-coefficient yalo ephantsi kakhulu yokukhuhlana. Ngexesha lokukhuhlana, iimolekyuli ze-PTFE kumphezulu wokudluliselwa kwinto yokukhwelana, zenza ifilimu yokudlulisa ezithambisayo ekhusela ilaphu leTeflon ngokwalo.

Impembelelo eyodwa yobunzima bemolekyuli ekusebenzeni :Uphononongo lubonisa ukuba kwi-Teflon ubushushu obuphezulu belaphu izicelo, i-PTFE esezantsi-ubunzima bemolekyuli  ihlala ibonisa ukuxhathisa ngcono ukunxiba. Oku kungenxa yokuba i-PTFE ephantsi kwe-molecular-weight inamatyathanga amafutshane emolekyuli kunye nokuhamba okuphezulu, okwenza ukwakheka ngokukhawuleza nokuzinza kwefilimu yokudlulisa esebenzayo ngexesha lokukhuhlana phakathi kwelaphu kunye nomsebenzi. Ngokuchaseneyo, ubunzima obuphezulu bemolekyuli ye-PTFE ikholisa ukubangela isimilo sokutyibilika kwintonga ngexesha lokukhuhlana, nto leyo enokwenza kube mandundu ukunxiba kwelaphu leTeflon lobushushu obuphezulu.

Ukuhanjiswa kobungakanani besuntswana kuqinisekisa ubunzulu bokungena kunye nokunamathela okufanayo kwengubo kwilaphu leTeflon elinobushushu obuphezulu, ngelixa ubunzima bemolekyuli buphucula ukusebenza kakuhle kwefilimu yokudlulisa i-self-lubricating. Kuphela ngokuqonda ngokunzulu kunye nokulawula ngokuchanekileyo ubudlelwane phakathi kwezi zinto zimbini zinokuthi ilaphu leTeflon elinobushushu obuphezulu linikwe ukusebenza okugqwesileyo okuchasene nokunxiba okufunekayo kwiimeko zokusebenza eziguquguqukayo zexesha elide, ukwandisa kakhulu ubomi bayo benkonzo ekuphekeni kokutya, ukomisa ukuprinta, i-photovoltaic lamination kunye nezinye iinkalo. I-Aokai New Materials igxile kwezi zalathisi ezincinci zokuqinisekisa ukusebenza okuzinzileyo kwe-macroscopic yelaphu leTeflon lobushushu obuphezulu.

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