Khoom noj khoom haus
Tricalcium phosphate yog cov khoom noj muaj txiaj ntsig zoo, feem ntau ntxiv rau hauv cov zaub mov los txhawb kev noj cov calcium, nws tseem tuaj yeem siv los tiv thaiv calcium deficiency lossis teeb meem noj qab haus huv los ntawm calcium deficiency.Tib lub sijhawm, tricalcium phosphate kuj tuaj yeem siv los ua tus neeg sawv cev tiv thaiv kab mob, PH tus nqi tswj hwm, tsis pub thiab lwm yam.Thaum siv rau hauv cov khoom noj, nws yog feem ntau siv hauv cov hmoov nplej los tiv thaiv cov khoom noj (dispersant), mis hmoov, khoom qab zib, paj npleg, seasoning, nqaij additives, tsiaj roj refining additives, poov xab zaub mov, thiab lwm yam.
Microencapsulated tricalcium phosphate, ib qho ntawm cov khoom siv calcium rau tib neeg lub cev, yog ib yam khoom siv calcium uas siv tricalcium phosphate ua raw khoom tom qab mus txog kev sib tsoo ultra-zoo, thiab tom qab ntawd tau ntim nrog lecithin rau hauv microcapsules uas muaj txoj kab uas hla ntawm 3-5 micrometers. .
Tsis tas li ntawd, tricalcium phosphate, raws li ib qho chaw ntawm calcium txhua hnub, muaj qhov zoo dua lwm cov tshuaj calcium hauv kev muab cov calcium thiab phosphorus.Ua kom muaj qhov sib npaug ntawm calcium thiab phosphorus hauv lub cev yog qhov tseem ceeb vim tias ob qho tib si cov zaub mov tseem ceeb rau kev tsim cov pob txha.Yog li yog tias qhov nyiaj tshuav no tsis tuaj yeem pom tau, nws feem ntau nyuaj rau kev ua tiav cov txiaj ntsig xav tau ntawm calcium ntxiv.
Kho mob
Tricalcium phosphate yog cov khoom siv zoo tshaj plaws rau kev kho thiab hloov ntawm tib neeg cov ntaub so ntswg tawv vim nws cov biocompatibility zoo, bioactivity thiab biodegradation.Nws tau raug mob siab rau hauv kev ua haujlwm ntawm biomedical engineering.α-tricalcium phosphate, β-tricalcium phosphate, feem ntau siv hauv tshuaj.β Tricalcium phosphate feem ntau yog tsim los ntawm calcium thiab phosphorus, nws muaj pes tsawg leeg zoo ib yam li cov khoom siv tsis zoo ntawm cov pob txha matrix, thiab nws khi zoo rau cov pob txha.
Tsiaj los yog tib neeg lub hlwb tuaj yeem loj hlob, sib txawv thiab rov ua dua qub ntawm cov khoom siv β-tricalcinum phosphate.Muaj ntau cov kev tshawb fawb sim ua pov thawj β- tricalcium phosphate, tsis muaj qhov tshwm sim tsis zoo, tsis muaj qhov tsis lees paub, tsis muaj tshuaj lom neeg mob, tsis muaj qhov tshwm sim tsis haum.Yog li ntawd, β Tricalcium phosphate tuaj yeem siv dav hauv kev sib koom tes thiab txha caj qaum, ceg ceg, qhov ncauj thiab maxillofacial phais, phais, thiab txhaws cov kab noj hniav.
Lwm daim ntawv thov:
siv hauv kev tsim cov iav opal, ceramic, xim, mordant, tshuaj, chiv, tsiaj pub additive, syrup clarifying tus neeg saib xyuas, yas stabilizer, thiab lwm yam.
