Iteknoloji yokugquma ngokuchanekileyo kwe-arhente yokulinganisa ubungakanani be-nanoscale, njengeteknoloji yanamhlanje, idlala indima ebalulekileyo ekuphuculeniukusebenza kweefayibha zeglasi. Izinto ezisetyenziswa kwi-nanomaterials, ngenxa yendawo yazo enkulu yomphezulu, umsebenzi oqinileyo womphezulu, kunye neempawu eziphezulu ze-physicochemical, zinokuphucula kakhulu ukuhambelana phakathi kwe-arhente yokulinganisa kunye nomphezulu wefayibha yeglasi, ngaloo ndlela zonyusa amandla azo okubopha phakathi kobuso. Ngokugquma ii-arhente zokulinganisa ze-nanoscale, ugquma olulinganayo noluzinzileyo lwe-nanoscale lunokwenziwa kumphezulu wefayibha yeglasi, luqinise ukunamathelana phakathi kwefayibha kunye ne-matrix, ngaloo ndlela luphucula kakhulu iimpawu zoomatshini zezinto ezidityanisiweyo. Kwizicelo ezisebenzayo, iinkqubo eziphambili ezifana nendlela ye-sol-gel, indlela yokutshiza, kunye nendlela yokudipha zisetyenziselwa ukugquma ii-arhente zokulinganisa ze-nanoscale ukuqinisekisa ukufana kunye nokunamathela kogquma. Umzekelo, ukusebenzisa i-arhente yokulinganisa equlethe i-nano-silane okanye i-nano-titanium, kwaye isetyenziswa ngokufanayo kumphezulu wefayibha yeglasi kusetyenziswa indlela ye-sol-gel, ifilimu ye-nanoscale SiO2 yenziwa kumphezulu wefayibha yeglasi, yandisa kakhulu amandla ayo omphezulu kunye nobudlelwane, kwaye yonyusa amandla ayo okubopha kunye ne-resin matrix.

2. Uyilo oluLungileyo lweeNxulumaniso ze-Agent zokulinganisa ubungakanani obudibeneyo ezininzi

Ngokudibanisa izinto ezininzi ezisebenzayo, iarhente yokulinganisa inokwenza uqweqwe olusebenzayo oluhlanganisiweyo kumphezulu wefayibha yeglasi, ihlangabezana neemfuno ezikhethekileyo zezinto ezidityanisiweyo zefayibha yeglasi kwiindawo ezahlukeneyo zokusetyenziswa. Iiarhente zokulinganisa ezininzi azinakuphucula kuphela amandla okubopha phakathi kweefayibha zeglasi kunye ne-matrix kodwa zikwanika neepropati ezahlukeneyo ezifana nokumelana nokugqwala, ukumelana ne-UV, kunye nokumelana notshintsho lobushushu. Ngokuphathelele uyilo oluphuculweyo, izinto ezinemisebenzi eyahlukeneyo yeekhemikhali zihlala zikhethwa, kwaye isiphumo sokusebenzisana sifezekiswa ngokulinganisela okufanelekileyo. Umzekelo, umxube wee-silane ezisebenzayo ezimbini kunye neepolymer zepolymer ezifana ne-polyurethane kunye ne-epoxy resin zinokwenza isakhiwo esidityanisiweyo ngokusebenzisa ii-chemical reactions ngexesha lenkqubo yokudibanisa, nto leyo ephucula kakhulu ukunamathelana phakathi kwefayibha yeglasi kunye ne-matrix. Kwiimfuno ezizodwa kwiindawo ezigqithisileyo ezifuna ukumelana nobushushu kunye nokumelana nokugqwala, inani elifanelekileyo lee-nanoparticles ze-ceramic ezimelana nobushushu obuphezulu okanye izinto zetyuwa yesinyithi ezimelana nokugqwala zingongezwa ukuphucula ngakumbi ukusebenza ngokubanzi kwezinto ezidityanisiweyo.

3. Ubuchule kunye noPhuculo kwiNkqubo yokuCoating ye-Agent yoKuncediswa yiPlasma

Inkqubo yokugquma i-arhente yokulinganisa ubungakanani encediswa yi-plasma, njengetekhnoloji entsha yokuguqula umphezulu, yenza ugquma olufanayo noluxineneyo kumphezulu weefayibha zeglasi ngokusebenzisa ukubekwa komphunga ngokwasemzimbeni okanye ukubekwa komphunga wekhemikhali ophuculweyo nge-plasma, nto leyo ephucula ngempumelelo amandla okubopha phakathi kwe-interfacial phakathiiifayibha zeglasikunye ne-matrix. Xa kuthelekiswa neendlela zemveli zokugquma i-agent yokulinganisa ubungakanani, inkqubo encediswa yi-plasma inokusabela kumphezulu wefayibha yeglasi ngokusebenzisa amasuntswana e-plasma anamandla aphezulu kubushushu obuphantsi, isuse ukungcola komphezulu kwaye ingenise amaqela asebenzayo, iphucula ukuzinza kwe-affinity kunye neekhemikhali zeefayibha. Emva kokugquma ngeefayibha zeglasi eziphathwe nge-plasma, ayizukuphuculwa nje kuphela amandla okubopha phakathi kwe-interfacial, kodwa inokubonelela ngemisebenzi eyongezelelweyo efana nokuxhathisa i-hydrolysis, ukuxhathisa i-UV, kunye nokuxhathisa umahluko wobushushu. Umzekelo, ukunyanga umphezulu wefayibha yeglasi ngenkqubo ye-plasma yobushushu obuphantsi kunye nokuyidibanisa ne-arhente yokulinganisa i-organosilicon kunokwenza i-coating enganyangekiyo nenganyangekiyo kubushushu obuphezulu, yandisa ubomi benkonzo yezinto ezidityanisiweyo. Izifundo zibonise ukuba amandla okuxinana kweefayibha zeglasi ezigqunywe ngeendlela ezincediswa yi-plasma anokwandiswa ngaphezulu kwe-25%, kwaye ukusebenza kwazo okulwa nokwaluphala kuphuculwe kakhulu kwiindawo ezitshintshanayo zobushushu kunye nokufuma.

4. Uphando malunga noYilo kunye neNkqubo yoLungiselelo lwee-Smart Responsive Sizing Agent Coatings

Iingubo ze-agent zokulinganisa eziphendulayo ezikrelekrele ziingubo ezinokuphendula kutshintsho olukwimeko-bume yangaphandle, kwaye zisetyenziswa kakhulu kwizixhobo ezikrelekrele, kwiisensa, nakwizinto ezidityanisiweyo eziziphilisayo. Ngokuyila ii-agent zokulinganisa ezinovakalelo olukwimeko-bume kubushushu, ukufuma, i-pH, njl.njl., ii-fiber zeglasi zinokulungisa ngokuzenzekelayo iipropati zazo zomphezulu phantsi kweemeko ezahlukeneyo, ngaloo ndlela zifezekisa imisebenzi ekrelekrele. Ii-agent zokulinganisa eziphendulayo ezikrelekrele zihlala zifezekiswa ngokungenisa ii-polymers okanye ii-molecules ezinemisebenzi ethile, ezivumela ukuba zitshintshe iipropati zazo ze-physicochemical phantsi kwezinto zangaphandle, ngaloo ndlela zifezekisa isiphumo esiguquguqukayo. Umzekelo, ukusebenzisa iingubo ze-agent zokulinganisa eziqulethe ii-polymers ezinovakalelo olukwimeko-bume okanye ii-polymers ezinovakalelo olukwimeko-bume ezifana ne-poly(N-isopropylacrylamide) kunokubangela ukuba ii-fiber zeglasi zitshintshe utshintsho lobushushu okanye kwiindawo ezine-acidic kunye ne-alkaline, zilungise amandla azo omphezulu kunye nokufuma. Ezi ngubo zivumela ii-fiber zeglasi ukuba zigcine ukunamathelana okufanelekileyo phakathi kobuso kunye nokuqina kwiindawo ezahlukeneyo zokusebenza [27]. Izifundo zibonise ukubaii-composites zefayibha yeglasiUkusebenzisa ii-coatings ezikrelekrele eziphendulayo kugcina amandla okuxinana azinzileyo phantsi kotshintsho lobushushu kwaye kubonisa ukumelana okuhle kakhulu nokugqwala kwiindawo ezine-asidi kunye ne-alkaline.
