Indlela ye-Agglomeration ye-nanoizinhlayiya

I-agglomeration ye-nanopowders ibhekisela kwinto yokuthi izinhlayiya eziyinhloko ze-nano zixhunywe komunye nomunye ngesikhathi senqubo yokulungiselela, ukuhlukaniswa, ukucubungula nokugcinwa, futhi amaqoqo amakhulu ezinhlayiyana akhiwa yizinhlayiya eziningi.

I-Agglomeration ihlukaniswe yaba izinhlobo ezithambile neziqinile.

I-agglomeration ethambile: ibhekisela kumaqoqo noma izinhlayiya ezincane ezakhiwe ngokuxhuma izinhlayiya eziyinhloko emaphoyinti noma ama-engeli, akhangiswe ezinhlayiyeni ezinkulu.Ngokuvamile kukholakala ukuthi kubangelwa ugesi ongashintshi kanye namandla e-Coulomb phakathi kwama-athomu nama-molecule endaweni eyimpuphu.

Kungani kwenzeka i-soft agglomeration?

Umphumela wosayizi, umphumela we-elekthronikhi ongaphezulu, umphumela wamandla angaphezulu, umphumela webanga eliseduze

I-Hard agglomeration: ibhekisela ezinhlayiyeni eziyinhloko ezixhunywe ubuso futhi azikwazi ukuhlukaniswa ngaphandle kwamandla angaphandle.Indawo engaphezulu incane kakhulu kunesamba sobuso bezinhlayiyana eyodwa, futhi kunzima kakhulu ukuphinde uhlakazeke.

Kungani kwenzeka i-agglomeration enzima?

Ithiyori yebhondi yekhemikhali, ithiyori ye-sintering, ithiyori ye-crystal bridge, ithiyori yebhondi ye-athomu engaphezulu 

Njengoba ukuhlangana kabusha kwezinto ze-nano kungenakugwema ngenxa yezakhiwo zabo ezikweletwayo, zingahlakazwa kanjani?

Ukuhlakazwa kwama-nano powders: okuthiwaukuhlakazeka kwe-nanopowderibhekisela enqubweni yokuhlukanisa nokuhlakaza izinhlayiya endaweni ewuketshezi futhi isatshalaliswe ngokulinganayo kulo lonke isigaba se-liquid, okuhlanganisa ikakhulukazi ukumanzisa, ukuhlukaniswa kwe-agglomeration kanye nokuqiniswa kwesiteji sezinhlayiya ezihlakazekile.

Ubuchwepheshe bokusabalalisa i-Nano powderkuyintoihlukaniswe ngokomzimba namakhemikhaliizindlela ngokuvamile.

Ukuhlakazeka ngokomzimba:

1. Ukuyaluza komshini nokuhlakazeka kuhlanganisa ukugaya, ukugaya ibhola elijwayelekile, isigayo sebhola elidlidlizayo, isigayo se-colloid, isigayo somoya, ukushukuma kwemishini kwesivinini esikhulu.

2. Ukuhlakazeka kwe-Ultrasonic

3. Ukwelashwa kwamandla aphezulu

Ukuhlakazwa kwamakhemikhali:

1. Ukuguqulwa kwamakhemikhali angaphezulu: indlela ye-ejenti yokuxhuma, ukusabela kwe-esterification, indlela yokuguqula i-graft graft

2. Ukuhlakazeka kwe-Disperant: ikakhulukazi nge-disperant adsorption ukuze uguqule ukusatshalaliswa kwe-surface charge yezinhlayiya, okuholela ekuzinzeni kwe-electrostatic kanye nokuqiniswa kwesithiyo esibulalayo ukuze kuzuzwe umphumela wokuhlakazeka.

Ukuhlakazwa kahle kuyisinyathelo esibalulekile sokuthola izakhiwo ezinhle kakhulu zezinto ze-nano.Kuyibhuloho phakathi kwezinto ze-nano kanye nokusetshenziswa okusebenzayo.

I-Hongwu Nano iphinde inikeze isevisi yokwenza ngokwezifiso ukwenza ama-nano powders ahlakazeke.

Kungani uHongwu Nano engasebenza kulo mkhakha?

1. Ngokusekelwe kokuhlangenwe nakho okucebile emkhakheni wama-nanomaterials

2. Thembela kubuchwepheshe be-nano obuthuthukisiwe

3. Gxila ekuthuthukisweni okugxile emakethe

4. Sihlose ukunikeza isevisi engcono kumakhasimende ethu
