Ngabe i-homogenizer ye-ultrasonic ingahle isetshenziselwe ukukhiqiza i-nanocell powder kusuka kumafutha?

Emcabangweni, ama-homogenizer e-ultrasonic angasiza ekukhiqizeni i-nano - i-powder cell cell kusuka esigabeni samafutha, kepha umphumela wangempela uvinjelwe yizici eziningi futhi udinga ukuhlawuliswa ngokuhlanganiswa nemibandela ethile:

1. Umsebenzi oyisisekelo we-homogenizer ye-ultrasonic
Ama-homogenizer we-ultrasonic asebenzisa ukuphakama - Ukudlidliza imvamisa (ngokuvamile ngenhla kwe-20KHZ) ukudala "umphumela we-cavitation": ama-bubble amancane akhiwa okuphakathi. Lapho la ma-bubbles ewa, akhipha umthelela oqinile wemishini kanye namabutho ama-shear, aphule izinhlayiya, ukuhlanganisa ama-applegate, futhi anciphise ama-micron - Lesi sici sibenza bakwazi ukulungele ukuphazamiseka kweseli kanye nokuhlaziywa kwe-powder.

2. Umthelela wesigaba samafutha
Uma usebenzisa i-OIL njengendlela yokuhlakazeka, kubalulekile ukucubungula ukulinganiselwa kwezindawo zalo ezibonakalayo ngomphumela we-ultrasound:
● ukusebenza kahle kwe-cavitation: Amafutha anengcindezi ephansi ye-vapor nokubonakala okuphezulu. Uma kuqhathaniswa namanzi, ukwakheka kanye nokuwa kwama-bubble we-cavitation abuthakathaka, okuphumela emandleni anganele ama-shear. Amandla aphezulu noma izikhathi zokuqhutshwa isikhathi eside kungadingeka ukuze kufezeke ukuhlukaniswa kwe-nanoscale.
● Ukuqina kokusabalalisa: Ama-Nanoscale cell powders athambekele ekuhlanganiseni ngenxa yamabutho e-van der Waals emafutheni. Ngakho-ke, ukungezwa kwamafutha - ama-surfible surficactants (afana nama-fatty acid esters noma ama-aillicone oil derivatives) kuyadingeka ukunciphisa amandla angaphezulu futhi alondoloze ukuhlakazeka kweNanoscale. Ngaphandle kwalokho, bangahle basebenzise ama-micron - izinhlayiya ezilinganayo.

3. Izici Zeseli
● Ukwakheka kweseli: Amaseli ezitshalo (aqukethe izindonga zamaseli) noma amagciwane (i-peptidoglycan, ungqimba oluqinile Ukwelashwa kwe-Ultrasonic kungadinga ukucacisa (njengokuqaqalwa kwamaqhwa noma i-enzymatic hydrolysis) ukuze kuphazamise ukuphazamiseka okusebenzayo. Amaseli ezilwane aswele izindonga zeseli futhi kulula kakhulu ukufuya nocezu.
● Isifundazwe sokuqala: Uma amaseli emanzi (aqukethe amanzi), isigaba samafutha singabangela ukomisa amaseli kanye noshintsho oluhlelekile, luthinta ukusebenza kabi kokuphazamiseka. Ama-powders e-cell amisiwe (njengamaseli we-Lyophilesed) afaneleke kakhulu ukuhlakazeka esigabeni samafutha.

Ama-homogenizer we-ultrasonic angakhiqiza i-nanoscale cell powders esigabeni samafutha, kepha lezi zimo kumele zihlangatshezwe:

● Lungiselela amapharamitha e-ultrasonic anjengamandla nobude obususelwa kuhlobo lweseli (e.g., amandla aphezulu amaseli aqinile);
● Faka uwoyela - ukudideka okuncibilikayo ukuvikela i-nanoparticle agglomeration;
● Kunokusebenzisa i-dry cell powder njengokuqukethwe okuluhlaza ukunciphisa ukuphazamiseka kokuzijabulisa esigabeni samafutha.
