Mokhoa oa Agglomeration oa nanolikaroloana
The agglomeration ea nanopowders e bua ka ketsahalo ea hore likaroloana tsa nano tse ka sehloohong li kopantsoe nakong ea ho lokisetsa, ho arohana, ho sebetsa le ho boloka, 'me lihlopha tse kholo tsa likaroloana li thehoa ke likaroloana tse ngata.
Agglomeration e arotsoe ka mefuta e bonolo le e thata.
Soft agglomeration: e bua ka lihlopha kapa likaroloana tse nyenyane tse entsoeng ka ho hokahanya likaroloana tsa mantlha lintlheng kapa li-angles, tse kentsoeng ka likaroloana tse kholo.Ka kakaretso ho lumeloa hore e bakoa ke motlakase o tsitsitseng le matla a Coulomb pakeng tsa liathomo le limolek'hule holim'a phofo.
Hobaneng ha agglomeration e bonolo e etsahala?
Matla a boholo, phello ea elektronike holim'a metsi, phello ea matla a holim'a metsi, phello e haufi-ufi
Agglomeration e thata: e bua ka likaroloana tse ka sehloohong li kopantsoe ke lifahleho 'me li ke ke tsa aroloa ntle le matla a ka ntle.Sebaka se kaholimo se nyane haholo ho feta kakaretso ea sebaka se kaholimo sa karolo e le 'ngoe, 'me ho thata haholo ho hasana hape.
Hobaneng ha agglomeration e thata e etsahala?
Khopolo ea Chemical bond, sintering theory, crystal bridge theory, surface athomo diffusion bond theory
Kaha ho kopana hape ha lisebelisoa tsa nano ho ke ke ha qojoa ka lebaka la thepa ea bona ea likoloto, li ka qhalakanngoa joang?
Phatlalatso ea nano powders: seo ho thoeng keho hasana ha nanopowdere bua ka mokhoa oa ho arola le ho qhala likaroloana ka har'a mokelikeli oa metsi le ho ajoa ka mokhoa o ts'oanang ho pholletsa le mokelikeli oa mokelikeli, oo haholo-holo o kenyelletsang ho kolobisa, de-agglomeration le botsitso ba likaroloana tse qhalakaneng sethaleng.
Theknoloji ea ho hasana ha phofo ea Nanokee arotsoe ka mmele le dikhemikhalemekhoa ka kakaretso.
Phasano ea 'mele:
1. Ho ferekana ha mochini le ho hasana ho kenyelletsa ho sila, leloala le tloaelehileng la bolo, leloala le thothomelang, leloala la colloid, leloala la moea, leloala le phahameng la mochini.
2. Ho hasana ha Ultrasonic
3. Phekolo ea matla a phahameng
Phatlalatso ea lik'hemik'hale:
1. Phetoho ea lik'hemik'hale tse holim'a metsi: mokhoa oa ho kopanya moemeli, karabelo ea esterification, mokhoa oa ho fetola holim'a graft
2. Dispersant hasane: haholo-holo ka dispersant adsorption ho fetola holim'a qoso kabo ea likaroloana, ho fella ka botsitso electrostatic le steric mokoallo botsitso ho finyella phello ea ho hasana.
Ho hasana hantle ke mohato oa bohlokoa oa ho fihlela thepa e ntle ka ho fetisisa ea thepa ea nano.Ke borokho lipakeng tsa lisebelisoa tsa nano le ts'ebeliso e sebetsang.
Hongwu Nano e boetse e fana ka ts'ebeletso ea ho itloaetsa ho etsa hore nano powders e hasane.
Hobaneng Hongwu Nano a ka sebetsa tšimong ee?
1. E itšetlehile ka phihlelo e ruileng tšimong ea nanomaterials
2. Itšetlehe ka theknoloji e tsoetseng pele ea nano
3. Tsepamisa maikutlo ho nts'etsopele e shebaneng le 'maraka
4. Sepheo sa ho fana ka litšebeletso tse molemo ho bareki ba rona
