Hydroxyapatite Particle Morphology: Maitiro Anoita Chimiro Chekuita Kwezvinhu 

Hydroxyapatite inoshandiswa zvakanyanya mukuchengetwa kwemuromo, zvinhu zvemazino, mapfupa ekugadzirisa zvinhu, kuisa machira uye biomedical composites. Kana vatengi vanoongorora hydroxyapatite hupfu, vanowanzo tarisa pane particle size, kuchena uye Ca / P ratio. Nekudaro, imwe yakakosha tekinoroji parameter inowanzo furatirwa: hydroxyapatite particle morphology.

Particle morphology inoreva chimiro, chimiro chepamusoro uye chimiro chemuviri chezvimedu zvehydroxyapatite. Zvichienderana nemaitiro ekugadzira uye maitiro ekugadzirisa, hydroxyapatite inogona kutaridzika seyakatenderera particles, tsono-yakafanana makristasi, tsvimbo-yakaita zvidimbu, ndiro-senge zvimiro, porous granules kana zvisina kujairika aggregates.

Kune mazino, kuchengetwa kwemuromo uye mapfupa ekugadzirisa mashandisirwo, particle morphology inogona kukanganisa kupararira, kugadzikana, kuyerera maitiro, kupindirana kwepamusoro, kusimba kwekubatanidza uye kugadzirisa kushanda. Ichi ndicho chikonzero vagadziri havafanirwe kusarudza hydroxyapatite poda yakavakirwa chete pakukura kwechikamu. Chimiro chechikamu chakakosha zvakare.

Chii? Hydroxyapatite Particle Morphology?

Hydroxyapatite particle morphology inotsanangura chimiro chemuviri uye chimiro chechimiro che hydroxyapatite particles. Pasi pekutarisa kwema microscopic, hydroxyapatite powder inogona kuratidza maitiro akasiyana, akadai se:

• Spherical particles
• Zvimedu zvakaita setsvimbo
• Makristasi akafanana netsono
• Plate-like particles
• Porous granules

• Micro-scale particles

Aya maumbirwo ane hukama zvakanyanya neiyo synthesis nzira, pH, reaction tembiricha, calcium sosi, phosphate sosi, nguva yekukwegura, nzira yekuomesa uye mushure mekurapa maitiro.

Semuenzaniso, kunaya kwemvura kunogona kuburitsa zvimedu zvakanaka zvine madhigirii akasiyana ekuunganidza. Hydrothermal synthesis inogona kubatsira kugadzira mamwe anodzorwa ekristaro maumbirwo akadai setsvimbo, tsono kana mahwendefa. Kurapa kwepamusoro-tembiricha kunogona kushandura crystallinity, kukura kwechikamu uye maitiro ekubatanidza.

Mumashandisirwo anoshanda, maviri ehydroxyapatite poda ane saizi yakafanana anogona kuita zvakasiyana kana morphology yavo yakasiyana. Izvi zvakanyanya kukosha kune vanogadzira, vanogadzira mazino zvinhu uye biomaterial vanogadzira.

Nei Particle Morphology Inokosha

Hydroxyapatite particle morphology inokanganisa maitiro ehupfu panguva yekugadzira, kugadzirisa uye kushandiswa. Kune vatengi veB2B, morphology haingori ruzivo rwemurabhoritari. Inogona kukanganisa chigadzirwa chekupedzisira.

1. Kupararira kwemaitiro

Kupararira ndechimwe chezvinonyanya kukosha kune hydroxyapatite poda inoshandiswa mumucheka wemazino, muromo, kumiswa kwekuchengetedza kwemuromo, machira uye zvinhu zvinosanganiswa.

Spherical or near-spherical particles anogona kupararira zviri nyore mune mamwe masisitimu nekuti ane micheto mishoma yakapinza uye anogona kuratidza mafambiro ari nani ekuyerera.
