Agglomeration usoro nke nanoirighiri ihe

Agglomeration nke nanopowders na-ezo aka n'ihe na-eme ka a na-ejikọta ihe ndị bụ isi nano na ibe ha n'oge usoro nkwadebe, nkewa, nhazi na nchekwa, na nnukwu ụyọkọ mkpụrụ osisi na-emepụta site na ọtụtụ ihe.

Agglomeration na-ekewa n'ime ụdị dị nro na nke siri ike.

Agglomeration dị nro: na-ezo aka na ụyọkọ ma ọ bụ obere ihe ndị e guzobere site na ijikọta ihe ndị bụ isi na isi ma ọ bụ akụkụ, nke na-adaba na nnukwu ihe. A na-ekwenyekarị na ọ bụ ọkụ eletrik static na ike Coulomb kpatara ya n'etiti atọm na ụmụ irighiri ihe dị n'elu ntụ ntụ.

Gịnị kpatara agglomeration dị nro ji eme?

Mmetụta nha, mmetụta eletrọnịkị elu, mmetụta ike elu, mmetụta nso nso

Agglomeration siri ike: na-ezo aka na ihe ndị bụ isi na-ejikọta site na ihu na enweghị ike ikewapụ na-enweghị ike mpụga. Ebe dị n'elu dị ntakịrị karịa nchikota nke elu nke otu ihe, ọ na-esikwa ike ịgbasa ọzọ.

Gịnị kpatara agglomeration siri ike ji eme?

Ozizi njikọ nke kemịkalụ, nkuzi sintering, tiori crystal bridge, surface atom diffusion bond theory 

Ebe ọ bụ na njikọta nke ihe nano bụ ihe a na-apụghị izere ezere n'ihi ihe onwunwe ha ji ụgwọ, olee otú ha ga-esi gbasasịa?

Mgbasa nke nano powders: nke a na-akpọnanopowder mgbasana-ezo aka na usoro nkewa na dispersing ahụ na mmiri mmiri na-ajụ na uniformly ekesa ofụri mmiri mmiri na-adọ, nke tumadi na-agụnye wetting, de-agglomeration na stabilization nke chụgara ahụ ogbo.

Teknụzụ mgbasa nke Nano ntụ ntụbụkewara n'ime anụ ahụ na kemikalusoro n'ozuzu.

Mgbasa nke anụ ahụ:

1. Mechanical agitation na dispersion gụnyere egweri, nkịtị bọọlụ igwe nri, vibratory bọl igwe nri, colloid igwe nri, ikuku igwe nri, n'ibu elu-ọsọ edemede.

2. Ultrasonic mgbasa

3. Ọgwụgwọ ike dị elu

Mgbasa kemịkalụ:

1. Mgbanwe kemịkalụ dị n'elu: usoro njikọ njikọta, mmeghachi omume esterification, usoro mgbanwe elu graft

2. Dispersant dispersion: tumadi site dispersant adsorption ịgbanwe elu ụgwọ nkesa nke ahụ, dapụtara na electrostatic stabilization na steric mgbochi stabilization iji nweta dispersion mmetụta.

Mgbasa nke ọma bụ isi nzọụkwụ iji nweta ihe kacha mma nke ihe nano. Ọ bụ akwa mmiri n'etiti ihe nano na ngwa bara uru.

Hongwu Nano na-enyekwa ọrụ nhazi iji mee ka nano powders gbasaa.

Gịnị mere Hongwu Nano ji nwee ike ije ozi n'ubi a?

1. Dabere na ahụmahụ bara ụba n'ọhịa nke nanomaterials

2. Dabere na Advanced nano technology

3. Lekwasị anya na mmepe nke dabere n'ahịa
