Agglomeration inji na nanobarbashi

Agglomeration na nanopowders yana nufin abin da ya faru cewa ƙwayoyin nano na farko suna haɗuwa da juna yayin aiwatar da shirye-shiryen, rabuwa, sarrafawa da adanawa, kuma manyan ƙwayoyin ƙwayoyin cuta suna samuwa ta hanyar ƙwayoyin cuta masu yawa.

An rarraba Agglomeration zuwa nau'i mai laushi da wuya.

Soft agglomeration: yana nufin gungu ko ƙananan barbashi da aka kafa ta hanyar haɗa ɓangarorin farko a maki ko kusurwoyi, waɗanda aka tallata akan manyan barbashi. An yi imani da cewa ana haifar da shi ta hanyar tsayayyen wutar lantarki da ƙarfin Coulomb tsakanin kwayoyin halitta da kwayoyin halitta a saman foda.

Me yasa m agglomeration ke faruwa?

Tasirin girman, tasirin lantarki na saman, tasirin makamashi na saman, tasirin kewayon kusa

Hard agglomeration: yana nufin ɓangarorin farko an haɗa su ta fuskoki kuma ba za a iya raba su ba tare da kuzarin waje ba. Yankin saman yana da ƙanƙanta fiye da jimlar farfajiyar ɓangarorin guda ɗaya, kuma yana da wuya a sake watsewa.

Me ya sa tsananin agglomeration ke faruwa?

Ka'idar haɗin gwiwa, ka'idar sintering, ka'idar gada, ka'idar atom diffusion bond 

Tunda haduwar kayan nano babu makawa saboda kadarorinsu na bashi, ta yaya za a tarwatsa su?

Watsawa na Nano powders: abin da ake kirananopowder watsawaYana nufin aiwatar da separating da dispersing barbashi a cikin ruwa matsakaici da kuma uniformly rarraba a ko'ina cikin ruwa lokaci, wanda yafi hada wetting, de-agglomeration da stabilization na tarwatsa barbashi mataki.

Nano foda watsa fasaharshinekasu kashi na zahiri da sinadaraihanyoyin gabaɗaya.

Watsewar jiki:

1. Mechanical agitation da watsawa sun hada da nika, talakawa ball niƙa, vibratory ball niƙa, colloid niƙa, iska niƙa, inji high-gudun stirring.

2. Ultrasonic watsawa

3. Magani mai ƙarfi

Watsewar sinadaran:

1. Surface sinadaran gyara: hada guda biyu wakili hanya, esterification dauki, surface graft gyara hanya

2. Dispersant watsawa: yafi ta dispersant adsorption canza surface cajin rarraba barbashi, sakamakon electrostatic stabilization da steric shãmaki karfafawa don cimma watsawa sakamako.

Watsawa da kyau shine babban mataki don cimma mafi kyawun kaddarorin kayan nano. Gada ce tsakanin kayan nano da aikace-aikace na zahiri.

Hongwu Nano kuma yana ba da sabis na keɓancewa don yin tarwatsa nano powders.

Me ya sa Hongwu Nano zai iya yin hidima a wannan fanni?

1. Dangane da kwarewa mai yawa a fagen nanomaterials

2. Dogara da Advanced Nano fasaha

3. Mai da hankali kan ci gaban kasuwa

4. Nufin bayar da mafi kyawun sabis ga abokan cinikinmu
