1. Ukuthuthukiswa Nokusetshenziswa Kobuchwepheshe Bokumboza Okunembile Kwe-Nanoscale Sizing Agent

Ubuchwepheshe bokumboza ngokunemba kwe-ejenti yokulinganisa ubukhulu be-nanoscale, njengobuchwepheshe obusezingeni eliphezulu, budlala indima ebalulekile ekuthuthukiseniukusebenza kwemicu yengilazi. Izinto ezisetshenziswayo, ngenxa yendawo yazo enkulu ethile, umsebenzi oqinile wobuso, kanye nezakhiwo ze-physicochemical eziphakeme, zingathuthukisa kakhulu ukuhambisana phakathi kwe-ejenti yokulinganisa kanye nobuso be-fiber yengilazi, ngaleyo ndlela zithuthukise amandla azo okubopha phakathi kobuso. Ngokumbozwa kwama-ejenti okulinganisa ama-nanoscale, ukwakheka kwe-nanoscale efanayo futhi okuzinzile kungakhiwa ebusweni be-fiber yengilazi, kuqinise ukunamathelana phakathi kwe-fiber kanye ne-matrix, ngaleyo ndlela kuthuthukise kakhulu izakhiwo zemishini zezinto ezihlanganisiwe. Ezisetshenzisweni ezisebenzayo, izinqubo ezithuthukisiwe ezifana nendlela ye-sol-gel, indlela yokufafaza, kanye nendlela yokucwilisa zisetshenziselwa ukugqoka ama-ejenti okulinganisa ama-nanoscale ukuqinisekisa ukufana nokunamathela kokugqoka. Isibonelo, kusetshenziswa i-ejenti yokulinganisa equkethe i-nano-silane noma i-nano-titanium, futhi isetshenziswe ngokufanayo ebusweni be-fiber yengilazi kusetshenziswa indlela ye-sol-gel, kwakheka ifilimu ye-nanoscale SiO2 ebusweni be-fiber yengilazi, okwandisa kakhulu amandla ayo obuso kanye nokusondelana, futhi kuthuthukise amandla ayo okubopha nge-resin matrix.

2. Umklamo Olungiselelwe Wezindlela Zokwenza Ama-Agent Okulinganisa Ahlanganisiwe Eziningi

Ngokuhlanganisa izingxenye eziningi ezisebenzayo, i-ejenti yokulinganisa ingakha ungqimba olusebenzayo oluhlanganisiwe ebusweni befayibha yengilazi, ihlangabezane nezidingo ezikhethekile zezinto ezihlanganisiwe zefayibha yengilazi emikhakheni ehlukene yokusetshenziswa. Ama-ejenti okulinganisa izingxenye eziningi awakwazi nje ukuthuthukisa amandla okubopha phakathi kwefayibha yengilazi kanye ne-matrix kodwa futhi awanike izakhiwo ezahlukahlukene njengokumelana nokugqwala, ukumelana ne-UV, kanye nokumelana nokushintsha kwezinga lokushisa. Ngokuphathelene nomklamo olungiselelwe, izingxenye ezinemisebenzi ehlukene yamakhemikhali zivame ukukhethwa, futhi umphumela wokubambisana utholakala ngezilinganiso ezifanele. Isibonelo, ingxube yama-polymer e-silane asebenzayo amabili kanye nama-polymer e-polymer njenge-polyurethane kanye ne-epoxy resin ingakha isakhiwo esixhumene ngokusabela kwamakhemikhali ngesikhathi senqubo yokuhlanganisa, okuthuthukisa kakhulu ukunamathelana phakathi kwefayibha yengilazi kanye ne-matrix. Ngezidingo ezikhethekile ezindaweni ezibucayi ezidinga ukumelana nokushisa kanye nokumelana nokugqwala, inani elifanele lama-nanoparticles e-ceramic amelana nokushisa okuphezulu noma izingxenye zikasawoti wensimbi ezimelana nokugqwala zingangezwa ukuze kuthuthukiswe ukusebenza okuphelele kwezinto ezihlanganisiwe.

3. Ukusungula Izinto Ezintsha kanye Nokuthuthuka Kwenqubo Yokumboza I-Agent Esizakala Nge-Plasma

Inqubo yokumboza i-ejenti yosayizi esizwa yi-plasma, njengobuchwepheshe obusha bokuguqulwa kobuso, yakha ungqimba olufanayo noluqinile ebusweni bemicu yengilazi ngokusebenzisa ukufakwa komusi ongokoqobo noma ukufakwa komusi wamakhemikhali othuthukisiwe yi-plasma, okuthuthukisa ngempumelelo amandla okubopha phakathi kwe-interfacial phakathiimicu yengilazikanye ne-matrix. Uma kuqhathaniswa nezindlela zendabuko zokumboza i-ejenti yosayizi, inqubo esizwa yi-plasma ingasabela ebusweni be-fiber yengilazi ngokusebenzisa izinhlayiya ze-plasma ezinamandla aphezulu emazingeni okushisa aphansi, isuse ukungcola kobuso futhi ingenise amaqembu asebenzayo, ithuthukise ukuqina kwe-affinity kanye namakhemikhali emicu. Ngemva kokumboza ngemicu yengilazi ephathwe nge-plasma, akugcini nje ngokuthi amandla okubopha phakathi kwe-interfacial angathuthukiswa kakhulu, kodwa futhi anganikeza imisebenzi eyengeziwe njengokumelana ne-hydrolysis, ukumelana ne-UV, kanye nokumelana nokwehluka kokushisa. Isibonelo, ukwelapha ubuso be-fiber yengilazi ngenqubo ye-plasma yokushisa okuphansi nokuyihlanganisa ne-ejenti yokulinganisa i-organosilicon kungakha ingubo emelana ne-UV futhi emelana nokushisa okuphezulu, kwandise impilo yenkonzo yezinto ezihlanganisiwe. Izifundo zibonise ukuthi amandla okudonseka e-fiber yengilazi ehlanganiswe ngezindlela ezisizwa yi-plasma angandiswa ngaphezu kwama-25%, futhi ukusebenza kwawo okulwa nokuguga kuthuthukiswa kakhulu ezindaweni ezishintshashintshayo zokushisa kanye nomswakama.

4. Ucwaningo ngenqubo yokuklama nokulungiselela i-Smart Responsive Sizing Agent Coatings

Izembozo ze-ejenti yokulinganisa ephendulayo ehlakaniphile ziyizembozo ezingasabela ezinguqukweni endaweni yangaphandle, futhi zisetshenziswa kabanzi ezintweni ezihlakaniphile, ezinzwa, nasezintweni ezihlanganisiwe eziziphilisayo. Ngokuklama ama-ejenti okulinganisa anokuzwela kwemvelo ekushiseni, emswakama, i-pH, njll., imicu yengilazi ingalungisa ngokuzenzakalelayo izakhiwo zayo zobuso ngaphansi kwezimo ezahlukene, ngaleyo ndlela ifeze imisebenzi ehlakaniphile. Ama-ejenti okulinganisa aphendulayo ahlakaniphile ngokuvamile atholakala ngokungenisa ama-polymer noma ama-molecule anemisebenzi ethile, ewavumela ukuthi ashintshe izakhiwo zawo ze-physicochemical ngaphansi kwethonya langaphandle, ngaleyo ndlela afeze umphumela oguquguqukayo. Isibonelo, ukusebenzisa izembozo ze-ejenti yokulinganisa eziqukethe ama-polymer azwela ekushiseni noma ama-polymer azwela ku-pH njenge-poly(N-isopropylacylamide) kungabangela ukuthi imicu yengilazi ibhekane nezinguquko zesimo sezulu ekushintsheni kwezinga lokushisa noma ezindaweni ezine-acidic ne-alkaline, kulungiswe amandla ayo obuso kanye nokumanzi. Lezi zembozo zivumela imicu yengilazi ukuthi igcine ukunamathela okuhle kakhulu kokuhlangana nokuqina ezindaweni ezahlukene zokusebenza [27]. Izifundo zibonise ukuthiizinhlanganisela zefayibha yengilaziUkusebenzisa izembozo ezihlakaniphile eziphendulayo kugcina amandla okunamathela azinzile ngaphansi kokushintsha kwezinga lokushisa futhi kukhombisa ukumelana okuhle kakhulu nokugqwala ezindaweni ezine-asidi ne-alkaline.
