I-Hydroxyapatite Particle Morphology: Indlela imilo echaphazela ngayo ukusebenza kwezinto 

I-Hydroxyapatite isetyenziswa ngokubanzi ekunakekelweni komlomo, izinto zamazinyo, izinto zokulungisa amathambo, ukufakwa kweengubo zokufakelwa kunye neengxube ze-biomedical. Xa abathengi bevavanya i-hydroxyapatite powder, bahlala begxininisa kwi-particle size, ubunyulu kunye ne-Ca / P ratio. Nangona kunjalo, enye iparameter yezobugcisa isoloko ingahoywa: i-hydroxyapatite particle morphology.

I-particle morphology ibhekiselele kwimilo, isakhiwo somphezulu kunye nenkangeleko ye-particle ye-hydroxyapatite. Ngokuxhomekeke kwindlela yokuvelisa kunye neemeko zenkqubo, i-hydroxyapatite inokuvela njengeengqungquthela ze-spherical, i-crystals efana nenaliti, i-particle-shaped-shaped, i-plate-like structures, i-porous granules okanye i-aggregates engaqhelekanga.

Ukunyamekela kwamazinyo, ukunakekelwa komlomo kunye nokulungiswa kwamathambo, i-particle morphology inokuchaphazela ukusabalalisa, ukuzinza, ukuziphatha okuhambayo, ukusebenzisana komhlaba, ukuqiniswa okudibeneyo kunye nokusebenza kokucubungula. Yingakho abavelisi akufanele bakhethe i-hydroxyapatite powder esekelwe kuphela kwi-particle size. Ukumila kwesuntswana kubalulekile.

Yintoni Inxalenye yeHydroxyapatite Imorphology?

I-Hydroxyapatite particle morphology ichaza ubume bomzimba kunye nefom yesakhiwo se-hydroxyapatite particles. Ngaphantsi kokuqwalaselwa kwe-microscopic, i-hydroxyapatite powder ingabonisa ukubonakala okuhlukeneyo, okunje:

I-Hydroxyapatite particle morphology idlala indima ebalulekileyo ekusebenzeni kwezinto. Ubume bunokuchaphazela ukusabalalisa, ukuhamba, i-rheology, ukusebenzisana komphezulu, ukuziphatha komatshini kunye nokuzinza kokuqulunqwa.

Kwiimveliso zokunakekelwa komlomo, i-morphology ichaphazela ukuthungwa kunye nokusabalalisa. Kwizinto zamazinyo, kuchaphazela ukuhambelana kwe-matrix kunye nokucubungula. Kwizinto zokulungisa amathambo, inokuchaphazela isakhiwo se-scaffold, i-porosity kunye nokusebenzisana kwezinto eziphilayo. Kwii-composites, i-morphology inokuchaphazela ukuqiniswa kunye nokufana kwezinto eziphathekayo.

Xa ukhetha i-hydroxyapatite powder, abathengi akufanele bajonge kuphela ubungakanani be-particle kunye nobunyulu. Kufuneka kwakhona bavavanye imorphology, aggregation, ukwakheka kwesigaba, umlinganiselo weCa/P kunye namaxwebhu ababoneleli.

I-hydroxyapatite morphology echanekileyo inokunceda abavelisi ukuba bakhe iimveliso ezingcono kunye nokusebenza okuzinzile, ukuqina kobugcisa obunamandla kunye nokulawula umgangatho othembekileyo.

FAQ

Yintoni i-hydroxyapatite particle morphology?

I-Hydroxyapatite i-particle morphology ibhekisela kwimilo kunye nesakhiwo somgangatho weengqungquthela ze-hydroxyapatite, ezifana ne-spherical, intonga-efana nenaliti, i-plate-like, i-porous okanye ifom engaqhelekanga.

Kutheni i-hydroxyapatite morphology ibalulekile?

I-Morphology ichaphazela ukusasazeka, ukuhambahamba, irheology, ukusebenzisana komphezulu, ukusebenza okuhlanganisiweyo kunye nokuziphatha kokucubungula.

Ngaba i-hydroxyapatite engqukuva ingcono kunenaliti efana ne-hydroxyapatite?

Akunjalo rhoqo. Amasuntswana angama-Spherical anokubonelela ngokuhamba ngcono kunye nokusasazwa, ngelixa amasuntswana afana nenaliti okanye amile okwentonga anokubonelela ngokudibana komphezulu owomeleleyo okanye ukomelezwa kwezinye ii-composites. Olona khetho lufanelekileyo luxhomekeke kwisicelo.

Yeyiphi imorphology efanelekileyo kwintlama yamazinyo?

Kwi-toothpaste, i-hydroxyapatite kufuneka ibe ne-dispersibility enhle, i-grittiness ephantsi kunye nokuziphatha okuzinzileyo. Iinqununu ezintle kunye nezihlakazekileyo zidla ngokuthandwa.

Yiyiphi i-morphology efanelekileyo kwizinto zokulungisa amathambo?

Kwizinto zokulungiswa kwamathambo, izakhiwo ze-porous, i-granules, i-scaffolds okanye i-morphology eyenzelwe ukusebenzisana kwezicubu kunokuba luncedo, kuxhomekeke kuyilo lokugqibela lwemveliso.

Abathengi banokujonga njani i-hydroxyapatite morphology?

Abathengi banokucela imifanekiso ye-SEM, idatha ye-TEM, ukusabalalisa ubungakanani be-particle, indawo ethile yendawo kunye namaxwebhu obugcisa avela kumthengisi.

Ngaba ubungakanani bamasuntswana buyafana nemorphology?

Hayi. Ubungakanani besuntswana buchaza ukuba amakhulu kangakanani amasuntswana, ngelixa imorphology ichaza imilo kunye nokwakheka kwawo. Zombini kufuneka zivavanywe kunye.
