Lijo

Tricalcium phosphate ke phepelo e bolokehileng ya dimatlafatsi, haholoholo e kentsweng dijong ho matlafatsa ho jewa ha calcium, e ka boela ya sebediswa ho thibela kgaello ya calcium kapa bothata bo botle bo bakwang ke khaello ya calcium.Ka nako e ts'oanang, tricalcium phosphate e ka boela ea sebelisoa e le anti-caking agent, PH value regulator, buffer joalo-joalo.Ha e sebelisoa lijong, hangata e sebelisoa ho phofo ea anti-caking agent (dispersant), phofo ea lebese, candy, pudding, seasoning, li-additives tsa nama, li-additives tse hloekisang oli ea liphoofolo, lijo tsa tomoso, joalo-joalo.

Microencapsulated tricalcium phosphate, e 'ngoe ea mehloli ea k'halsiamo' meleng oa motho, ke mofuta oa sehlahisoa sa calcium se sebelisang tricalcium phosphate e le lisebelisoa tse tala ka mor'a ho sila ka mokhoa o hlakileng, ebe o kenngoa ka lecithin ka har'a li-microcapsules tse nang le bophara ba li-micrometer tse 3-5. .

Ho feta moo, tricalcium phosphate, joalo ka mohloli oa letsatsi le letsatsi oa k'halsiamo, e na le molemo ho feta lisebelisoa tse ling tsa calcium ho fana ka calcium le phosphorus ka bobeli.Ho boloka tekano pakeng tsa calcium le phosphorus 'meleng ke habohlokoa hobane liminerale ka bobeli li bohlokoa bakeng sa ho thehoa ha masapo.Kahoo haeba tekanyo ena e ke ke ea phethahala, hangata ho thata ho finyella phello e lakatsehang ea calcium supplementation.

Tricalcium phosphate ke sesebediswa se nepahetseng bakeng sa ho lokisa le ho nkela sebaka sa dithishu tse thata tsa motho ka lebaka la ho sebetsa ha tsona hantle, bioactivity le biodegradation.E 'nile ea lebisoa tlhokomelo e kholo lefapheng la boenjiniere ba biomedical.α-tricalcium phosphate, β-tricalcium phosphate, hangata e sebelisoa meriana.β Tricalcium phosphate haholo-holo e entsoe ka k'halsiamo le phosphorus, sebopeho sa eona se tšoana le likaroloana tsa inorganic tsa matrix ea masapo, 'me e tlamahane hantle lesapo.

Lisele tsa liphoofolo kapa tsa motho li ka hola, tsa arola le ho ikatisa ka mokhoa o tloaelehileng holim'a thepa ea phosphate β-tricalcinum.Palo e kholo ea liphuputso tsa liteko li paka β-tricalcium phosphate, ha e na karabelo e mpe, ha e na karabelo ea ho hana, ha e na chefo e matla, ha e na ntho e hananang le eona.Ka hona, β Tricalcium phosphate e ka sebelisoa haholo ho kopanngoa ha lenonyello le mokokotlo, maoto le matsoho, opereishene ea molomo le ea maxillofacial, ho buuoa, le ho tlatsa likheo tsa periodontal.

Sesebelisoa se seng:

E sebelisoa ha ho etsoa likhalase tsa opal, ceramic, pente, mordant, meriana, manyolo, setlolo sa phepelo ea liphoofolo, sesebelisoa sa ho hlakisa sirapo, stabilizer ea polasetiki, jj.
