I-Cosmetic Materials I-Micron/Nano Hydroxyapatite Powder
Incazelo Yomkhiqizo
I-Hydroxyapatite iyimaminerali eyenzeka ngokwemvelo ingxenye yayo eyinhloko i-calcium phosphate. Iyingxenye eyinhloko yamathambo namazinyo omuntu futhi inokuhambisana okuhle kwe-biocompatibility kanye ne-bioactivity. Okulandelayo yisingeniso esinemininingwane ye-hydroxyapatite:
1. Izakhiwo zamakhemikhali
Igama Lekhemikhali: Hydroxyapatite
I-Chemical Formula: Ca10(PO4)6(OH)2
Isisindo samangqamuzana: 1004.6 g/mol
2.Izakhiwo Zomzimba
Ukubukeka: I-Hydroxyapatite ngokuvamile i-powder emhlophe noma emhlophe noma i-crystal.
Ukunyibilika: Incibilika kancane emanzini, kodwa incibilika kakhulu ezixazululweni ezine-asidi.
I-Crystal Structure: I-Hydroxyapatite ine-hexagonal crystal structure, efana nesakhiwo sekristalu samathambo namazinyo emvelo.

Umsebenzi
Ukulungisa Amathambo Nokuvuselelwa Kabusha
I-1.I-Bone Graft Material: I-Hydroxyapatite isetshenziswa kabanzi ekuhlinzeni ukufakelwa kwamathambo njengento yokugcwalisa amathambo ukusiza ukulungisa nokuvuselela izicubu zamathambo.
I-2.Impahla yokulungisa amathambo: I-Hydroxyapatite isetshenziselwa ukulungiswa kwe-fracture nokugcwalisa ukukhubazeka kwamathambo, ukukhuthaza ukukhula kwamangqamuzana amathambo nokuvuselelwa kwezicubu zethambo.
Izicelo Zamazinyo
I-1.Ukulungiswa Kwamazinyo: I-Hydroxyapatite isetshenziselwa izinto zokubuyisela amazinyo ezifana nokugcwaliswa kwamazinyo kanye nokufakwa kwezinyo ukusiza ukulungisa ukulimala kwamazinyo kanye nemigodi.
I-2.I-Toothpaste Additive: I-Hydroxyapatite, njengesithako esisebenzayo ku-toothpaste, isiza ukulungisa uqweqwe lwamazinyo, ukunciphisa ukuzwela kwamazinyo, nokuthuthukisa ikhono lokulwa ne-caries yezinyo.
Izicelo ze-Biomedical
I-1.Biomatadium: I-Hydroxyapatite isetshenziselwa ukwenza ama-biomaterials, njengamathambo okufakelwa, amalunga okwenziwa kanye nama-bioceramics, futhi inokubambisana okuhle kanye ne-bioactivity.
I-2.Isithwali Sezidakamizwa: I-Hydroxyapatite isetshenziselwa abathwali bezidakamizwa ukusiza ukulawula ukukhululwa kwezidakamizwa nokuthuthukisa i-bioavailability yezidakamizwa.
Izimonyo kanye Nemikhiqizo Yokunakekelwa Kwesikhumba
I-1.Imikhiqizo yokunakekelwa kwesikhumba: I-Hydroxyapatite isetshenziswa emikhiqizweni yokunakekelwa kwesikhumba ukusiza ukulungisa umgoqo wesikhumba nokuthuthukisa ikhono lokuthambisa isikhumba.
I-2.Izimonyo: I-Hydroxyapatite isetshenziselwa izimonyo njenge-agent ye-sunscreen ebonakalayo ukuze inikeze ukuvikelwa kwelanga nokunciphisa ukulimala kwe-UV esikhumbeni.
Isicelo
Ezokwelapha kanye Nezamazinyo
I-1.I-Orthopedic Surgery: I-Hydroxyapatite isetshenziselwa ukuhlinzwa kwamathambo njengempahla ye-graft yamathambo kanye nezinto zokulungisa amathambo ukuze kusize ukulungisa nokuvuselela izicubu zethambo.
2.Ukubuyiselwa Kwamazinyo: I-Hydroxyapatite isetshenziselwa izinto zokubuyisela amazinyo ukusiza ukulungisa ukulimala kwamazinyo kanye nama-caries nokuthuthukisa ikhono lokulwa ne-caries yezinyo.
Izinto eziphilayo
I-1.I-Artificial Bone kanye namaJoyinti: I-Hydroxyapatite isetshenziselwa ukwenza amathambo okufakelwa kanye namalunga okufakelwa futhi ine-biocompatibility enhle kanye ne-bioactivity.
I-2.Bioceramics: I-Hydroxyapatite isetshenziselwa ukwenziwa kwe-bioceramics, esetshenziswa kabanzi ku-orthopedics kanye namazinyo.
Izimonyo kanye Nemikhiqizo Yokunakekelwa Kwesikhumba
I-1.Imikhiqizo yokunakekelwa kwesikhumba: I-Hydroxyapatite isetshenziswa emikhiqizweni yokunakekelwa kwesikhumba ukusiza ukulungisa umgoqo wesikhumba nokuthuthukisa ikhono lokuthambisa isikhumba.
