1. Kupanga ndi Kugwiritsa Ntchito Ukadaulo wa Nanoscale Sizing Agent Precision Coating

Ukadaulo wolondola wa nanoscale size agent wokutira, monga ukadaulo wamakono, umagwira ntchito yofunika kwambiri pakukonzamagwiridwe antchito a ulusi wagalasi. Zinthu za nanomaterials, chifukwa cha malo awo akuluakulu, mphamvu ya pamwamba, komanso mphamvu zapamwamba za physicochemical, zimatha kusintha kwambiri kugwirizana pakati pa chinthu choyezera kukula ndi pamwamba pa ulusi wagalasi, motero zimawonjezera mphamvu zawo zolumikizirana pakati pa nkhope. Kudzera mu chophimba cha zinthu zoyezera kukula kwa nanoscale, chophimba cha nanoscale chofanana komanso chokhazikika chingapangidwe pamwamba pa ulusi wagalasi, kulimbitsa kugwirizana pakati pa ulusi ndi matrix, motero kumawongolera kwambiri mawonekedwe a makina a zinthu zophatikizika. Mu ntchito zenizeni, njira zapamwamba monga njira ya sol-gel, njira yopopera, ndi njira yoviika zimagwiritsidwa ntchito pophimba zinthu zoyezera kukula kwa nanoscale kuti zitsimikizire kufanana ndi kumatirira kwa chophimbacho. Mwachitsanzo, pogwiritsa ntchito chinthu choyezera kukula chomwe chili ndi nano-silane kapena nano-titanium, ndikuchigwiritsa ntchito mofanana pamwamba pa ulusi wagalasi pogwiritsa ntchito njira ya sol-gel, filimu ya nanoscale SiO2 imapangidwa pamwamba pa ulusi wagalasi, zomwe zimawonjezera kwambiri mphamvu yake pamwamba ndi kuyanjana, ndikuwonjezera mphamvu yake yolumikizira ndi resin matrix.

2. Kapangidwe Koyenera ka Mapangidwe Azinthu Zambiri Zogwirizana ndi Kusanja kwa Agent

Mwa kuphatikiza zigawo zingapo zogwira ntchito, chopangira kukula chingapange chophimba chogwira ntchito chophatikizana pamwamba pa ulusi wagalasi, kukwaniritsa zosowa zapadera za zipangizo zopangira ulusi wagalasi m'magawo osiyanasiyana ogwiritsira ntchito. Zinthu zopangira kukula kwa magawo ambiri sizimangowonjezera mphamvu yolumikizirana pakati pa ulusi wagalasi ndi matrix komanso zimawapatsa zinthu zosiyanasiyana monga kukana dzimbiri, kukana UV, komanso kukana kusintha kwa kutentha. Ponena za kapangidwe kabwino, zigawo zomwe zili ndi zochita zosiyanasiyana zamakemikolo nthawi zambiri zimasankhidwa, ndipo zotsatira zake zimatheka kudzera mu kuchuluka koyenera. Mwachitsanzo, chisakanizo cha ma polima awiri a silane ndi ma polymer monga polyurethane ndi epoxy resin zimatha kupanga kapangidwe kolumikizana kudzera muzochita zamakemikolo panthawi yopangira utoto, zomwe zimawonjezera kwambiri kumamatirana pakati pa ulusi wagalasi ndi matrix. Pazofunikira zapadera m'malo ovuta kwambiri omwe amafunikira kukana kutentha ndi kukana dzimbiri, kuchuluka koyenera kwa tinthu tating'onoting'ono ta ceramic tosagwira kutentha kwambiri kapena zigawo zamchere zachitsulo zosagwira dzimbiri zitha kuwonjezeredwa kuti ziwongolere magwiridwe antchito onse a zinthu zopangira.

3. Zatsopano ndi Kupambana mu Njira Yopangira Zophimba Zothandizira Kulemera kwa Plasma

Njira yophikira yothandizidwa ndi plasma, monga ukadaulo watsopano wosinthira pamwamba, imapanga chophimba chofanana komanso chokhuthala pamwamba pa ulusi wagalasi kudzera mu kuyika nthunzi yeniyeni kapena kuyika nthunzi ya mankhwala yowonjezeredwa ndi plasma, zomwe zimapangitsa kuti mphamvu yolumikizirana pakati pa zinthu ziwiri iziyenda bwino.ulusi wagalasindi matrix. Poyerekeza ndi njira zachikhalidwe zopangira kukula kwa chinthu, njira yothandizidwa ndi plasma imatha kuchitapo kanthu ndi pamwamba pa ulusi wagalasi kudzera mu tinthu ta plasma tokhala ndi mphamvu zambiri kutentha kochepa, kuchotsa zonyansa pamwamba ndikuyambitsa magulu ogwira ntchito, kukulitsa kulimba kwa ulusi ndi mankhwala. Pambuyo popaka ulusi wagalasi wothiridwa ndi plasma, sikuti mphamvu yolumikizirana pakati pa nkhope yokha ingawongoleredwe kwambiri, komanso ingapereke ntchito zina monga kukana hydrolysis, kukana kwa UV, ndi kukana kusiyana kwa kutentha. Mwachitsanzo, kuchiza pamwamba pa ulusi wagalasi ndi njira ya plasma yotsika kutentha ndikuyiphatikiza ndi chinthu chopangira kukula kwa organosilicon kungapangitse utoto wokana UV komanso wokana kutentha kwambiri, kukulitsa moyo wa ntchito ya chinthu chophatikiza. Kafukufuku wasonyeza kuti mphamvu yokoka ya zinthu zopangira ulusi wagalasi zokutidwa ndi njira zothandizira plasma zitha kuwonjezeka ndi zoposa 25%, ndipo magwiridwe antchito awo oletsa kukalamba amawonjezeka kwambiri m'malo osinthira kutentha ndi chinyezi.

4. Kafukufuku pa Kapangidwe ndi Kukonzekera kwa Zophimba Zanzeru Zoyankha Pang'ono

Zophimba zanzeru zoyankha kukula ndi zophimba zomwe zimatha kuyankha kusintha kwa chilengedwe chakunja, ndipo zimagwiritsidwa ntchito kwambiri muzinthu zanzeru, masensa, ndi zinthu zodzipangira zokha. Mwa kupanga zophimba zanzeru zomwe zimakhudzidwa ndi kutentha, chinyezi, pH, ndi zina zotero, ulusi wagalasi ukhoza kusintha zokha mawonekedwe awo pamwamba pa zinthu zosiyanasiyana, motero kukwaniritsa ntchito zanzeru. Zophimba zanzeru zoyankha kukula nthawi zambiri zimapezeka poyambitsa ma polima kapena mamolekyu okhala ndi ntchito zinazake, zomwe zimawalola kusintha mawonekedwe awo a physicochemical pansi pa zoyambitsa zakunja, motero zimapangitsa kuti zikhale zosinthika. Mwachitsanzo, kugwiritsa ntchito zophimba zamphamvu zojambulira zomwe zili ndi ma polima omwe amakhudzidwa ndi kutentha kapena ma polima omwe amakhudzidwa ndi pH monga poly(N-isopropylacylamide) kungayambitse ulusi wagalasi kusintha kwa mawonekedwe a kutentha kapena malo okhala ndi acidic ndi alkaline, kusintha mphamvu zawo pamwamba ndi kunyowa. Zophimba izi zimalola ulusi wagalasi kusunga kulumikizidwa bwino komanso kulimba m'malo osiyanasiyana ogwirira ntchito [27]. Kafukufuku wasonyeza kutizosakaniza zagalasi la ulusiKugwiritsa ntchito zokutira zanzeru zomwe zimayankha bwino kumasunga mphamvu yolimba yolimba kutentha kukasinthasintha ndipo kumawonetsa kukana dzimbiri bwino m'malo okhala ndi asidi komanso alkaline.
