Habka Agglomeration ee nanoqaybo

Agglomeration ee nanopowders waxaa loola jeedaa ifafaale ah in qaybaha nano aasaasiga ah ay isku xiran yihiin midba midka kale inta lagu jiro habka diyaarinta, kala-soocidda, farsamaynta iyo kaydinta, iyo kooxo waaweyn oo qayb ka mid ah ayaa sameeyay qaybo badan.

Agglomeration waxaa loo qaybiyaa noocyo jilicsan iyo kuwo adag.

Agglomeration jilicsan: waxaa loola jeedaa rucubyo ama qaybo yaryar oo lagu sameeyay isku xirka qaybaha asaasiga ah ee dhibcaha ama xaglaha, kuwaas oo lagu dhajiyay qaybo waaweyn.Waxaa guud ahaan la rumeysan yahay inay sababtay koronto taagan iyo xoogga Coulomb ee u dhexeeya atamka iyo molecules ee dusha budada ah.

Waa maxay sababta jilicsanaanta jilicsani u dhacdo?

Saamaynta cabbirka, saamaynta elektarooniga ah ee dusha sare, saamaynta tamarta dusha sare, saamaynta fogaanta dhow

Hard agglomeration: waxaa loola jeedaa qaybaha aasaasiga ah waxaa ku xiran weji oo aan la kala saari karin iyada oo aan tamar dibadda ah.Aagga dusha sare ayaa aad uga yar marka loo eego wadarta dusha sare ee hal qayb, aad bayna u adagtahay in mar kale la kala diro.

Waa maxay sababta gardarrada adag u dhacdo?

Aragtida curaarta kiimikada, aragtida sintering, aragtida buundada crystal, aragtida curaarta faafinta atomka 

Mar haddii isu imaatinka alaabta nano ay tahay lama huraan sababtoo ah hantidooda lagu leeyahay, sidee loo kala firdhi karaa?

Kala firdhinta budada nano: waxa loogu yeerokala firdhiso nanopowderWaxa loola jeedaa habka kala-soocidda iyo kala firdhinta qaybaha dareeraha dhexdhexaadka ah oo si isku mid ah loo qaybiyey inta lagu jiro marxaladda dareeraha, taas oo inta badan ka mid ah qoynta, de-agglomeration iyo xasilinta marxaladda qaybaha kala firdhiyey.

Farsamaynta faafinta budada Nanowaau qaybsama jirka iyo kiimikaadhababka guud ahaan.

Kala firdhinta jidhka:

1. Kacsiga makaanikada iyo kala firdhinta waxaa ka mid ah shiidi, mishiinka kubbadda caadiga ah, mishiinka kubbadda gariirta, warshadda kolloid, mishiinka hawada, karitaanka xawaaraha sare ee farsamada

2. Kala-baxa Ultrasonic

3. Daaweynta tamarta sare

Kala firdhiso kiimiko:

1. Wax ka beddelka kiimikaad dusha sare: Habka wakiilka isku xidhka, falcelinta esterification, habka wax ka beddelka tallaalka dusha sare

2. Kala firdhisanaanta: inta badan iyada oo loo marayo xayeysiinta kala firdhisan si loo beddelo qaybinta kharashka dusha sare ee walxaha, taasoo keentay xasilinta korantada iyo xasilinta xannibaadda steric si loo gaaro saameynta kala firidhsan.

Kala firdhinta wanaagsan waa tillaabada muhiimka ah si loo gaaro sifooyinka ugu wanaagsan ee alaabta nano.Waa buundada u dhaxaysa alaabta nano iyo codsiga la taaban karo.

Hongwu Nano waxa kale oo ay bixisaa adeega is-habaynta si loo sameeyo kala firdhiso budada nano.

Muxuu Hongwu Nano uga shaqayn karaa goobtan?

1. Iyada oo ku saleysan khibrad qani ah oo ku saabsan berrinka nanomaterials

2. Ku tiirso tignoolajiyada horumarsan ee nano

3. In xooga la saaro horumarinta suuqa ku jihaysan

4. Ujeedo inaan u soo bandhigno macaamiisheena adeeg wanaagsan
