Khoom noj

Tricalcium phosphate yog ib yam khoom noj khoom haus zoo uas muaj kev nyab xeeb, feem ntau yog ntxiv rau hauv cov khoom noj kom txhawb nqa kev noj calcium, nws kuj tseem siv tau los tiv thaiv kev tsis txaus calcium lossis teeb meem kev noj qab haus huv uas tshwm sim los ntawm kev tsis txaus calcium. Tib lub sijhawm, tricalcium phosphate kuj tseem siv tau ua tus neeg sawv cev tiv thaiv kev sib sau ua ke, tus nqi PH tswj, buffer thiab lwm yam. Thaum siv rau hauv cov khoom noj khoom haus, nws feem ntau siv rau hauv hmoov nplej tiv thaiv kev sib sau ua ke (dispersant), mis hmoov, khoom qab zib, pudding, seasoning, nqaij ntxiv, roj tsiaj ntxiv, khoom noj poov xab, thiab lwm yam.

Microencapsulated tricalcium phosphate, yog ib qho ntawm cov calcium uas tib neeg lub cev tau txais, yog ib hom khoom calcium uas siv tricalcium phosphate ua cov khoom siv raw tom qab sib tsoo zoo heev, thiab tom qab ntawd raug encapsulated nrog lecithin rau hauv cov microcapsules uas muaj txoj kab uas hla ntawm 3-5 micrometers.

Ntxiv mus, tricalcium phosphate, ua ib qho chaw muab calcium txhua hnub, muaj qhov zoo dua li lwm cov tshuaj calcium hauv kev muab ob qho tib si calcium thiab phosphorus. Kev tswj hwm qhov sib npaug ntawm calcium thiab phosphorus hauv lub cev yog qhov tseem ceeb vim tias ob qho tib si minerals yog qhov tseem ceeb rau kev tsim pob txha. Yog li ntawd, yog tias qhov sib npaug no tsis tuaj yeem ua tiav, nws feem ntau nyuaj rau kev ua tiav cov txiaj ntsig xav tau ntawm kev noj calcium ntxiv.

Kev Kho Mob

Tricalcium phosphate yog ib yam khoom zoo tshaj plaws rau kev kho thiab hloov cov nqaij tawv ntawm tib neeg vim nws qhov kev sib raug zoo, kev ua haujlwm zoo thiab kev puas tsuaj ntawm lub cev. Nws tau raug saib xyuas zoo hauv kev tsim kho biomedical. α-tricalcium phosphate, β-tricalcium phosphate, feem ntau siv hauv tshuaj. β Tricalcium phosphate feem ntau yog tsim los ntawm calcium thiab phosphorus, nws cov khoom sib xyaw zoo ib yam li cov khoom inorganic ntawm cov pob txha matrix, thiab nws khi zoo rau pob txha.

Cov hlwb tsiaj lossis tib neeg tuaj yeem loj hlob, sib txawv thiab rov tsim dua li qub ntawm cov khoom siv β-tricalcinum phosphate. Muaj ntau qhov kev tshawb fawb sim ua pov thawj tias β-tricalcium phosphate, tsis muaj kev tsis haum tshuaj, tsis muaj kev tsis lees paub, tsis muaj kev phiv tshuaj lom, tsis muaj kev ua xua. Yog li ntawd, β-Tricalcium phosphate tuaj yeem siv dav hauv kev sib koom ua ke ntawm cov pob qij txha thiab pob txha caj qaum, ceg, phais qhov ncauj thiab lub ntsej muag, phais, thiab txhaws cov kab noj hniav.

Lwm daim ntawv thov:

siv rau hauv kev tsim cov iav opal, ceramic, xim, mordant, tshuaj, chiv, khoom noj tsiaj ntxiv, tus neeg sawv cev syrup clarifying, yas stabilizer, thiab lwm yam.
