Tilmaamaha jirka

Muuqaalka iyo sifooyinka: cad, aan ur lahayn, crystal aan dhadhan lahayn ama budada amorphous.

Barta dhalaalka (℃): 1670

Solubility: aan biyo ku milmin, aan milmin ee ethanol, acetic acid, milmay acid.

Nooca heerkulka sare ee α waxaa iska leh nidaamka monoclinic, cufnaanta qaraabada waa 2.86 g / cm3;Heerkulka hoose ee nooca β wejiga waxaa iska leh nidaamka kristal ee laba geesoodka ah iyo cufnaantiisa qaraabadu waa 3.07 g/cm3.

Cunto

Tricalcium phosphate waa xoojiye nafaqeeyayaal badbaado leh, oo inta badan lagu daro cuntada si loo xoojiyo qaadashada kaalshiyamka, waxa kale oo loo isticmaali karaa si looga hortago yaraanta calcium ama dhibaato caafimaad oo ay keento yaraanta calcium.Isla mar ahaantaana, tricalcium fosfooraska ayaa sidoo kale loo isticmaali karaa sida wakiilka ka-hortagga-caking, PH qiimaha jaangooyooyinka, kaydinta iyo wixii la mid ah.Marka loo isticmaalo cuntada, waxaa caadi ahaan loo isticmaalaa daqiiqda wakiilka ka-hortagga-caking (dispersant), budada caanaha, nacnaca, pudding, xawaash, waxyaabaha lagu daro hilibka, lagu daro saliidda xoolaha, cuntada khamiirka, iwm.

Microencapsulated tricalcium phosphate, mid ka mid ah ilaha calcium ee jidhka bini'aadamka, waa nooc ka mid ah wax soo saarka calcium u isticmaala tricalcium phosphate sida alaabta ceeriin ka dib markii la shiiday ultra-fine, ka dibna lagu daboolay lecithin galay microcapsules oo leh dhexroor 3-5 micrometers. .

Intaa waxaa dheer, tricalcium fosfooraska, oo ah isha maalinlaha ah ee kalsiyumka, ayaa faa'iido u leh kaalshiyamyada kale ee kaalshiyamka ah ee bixinta calcium iyo fosfooraska labadaba.Isku dheelli tirka kaalshiyamka iyo fosfooraska ee jirka waa muhiim sababtoo ah labada macdan ayaa lagama maarmaan u ah sameynta lafaha.Markaa haddii dheellitirkan aan la xaqiijin karin, inta badan way adag tahay in la gaaro saameynta la rabo ee kaalshiyamka.

Caafimaad

Tricalcium phosphate waa shay ku haboon hagaajinta iyo bedelida unugyada adag ee bini'aadamka sababtoo ah laqabsigeeda wanaagsan ee noole noolaha iyo noole degista.Waxa si weyn loogu fiirsaday dhinaca injineernimada bayoolajiga.α-tricalcium phosphate, β-tricalcium phosphate, ayaa inta badan loo isticmaalaa daawada.β Tricalcium phosphate waxay inta badan ka kooban tahay kalsiyum iyo fosfooraska, ka koobankeedu wuxuu la mid yahay qaybaha aan organic ahayn ee matrixka lafaha, waxayna si fiican ugu xidhaa lafaha.

Unugyada xayawaanka ama bani-aadmiga ayaa kori kara, kala saari kara oo si caadi ah ugu soo saari kara maadada fosfateet ee β-tricalcinum.Tiro badan oo daraasado tijaabo ah ayaa caddeeyey phosphate β-tricalcium, oo aan lahayn falcelin xun, ma laha falcelin diidmo ah, fal-celin sun ah oo degdeg ah, malaha ifafaale xasaasiyadeed.Sidaa darteed, β Tricalcium phosphate waxaa si weyn loogu isticmaali karaa isku-dhafka laf-dhabarka iyo laf-dhabarka, addimada, qalliinka afka iyo maxillofacial, qalliin, iyo buuxinta godadka periodontal.

Codsi kale:

loo isticmaalo soo saarista muraayadaha opal, dhoobada, rinjiga, mordant, daawada, bacriminta, wax lagu daro quudinta xoolaha, wakiilka caddaynaya sharoobada, xasiliyaha caaga ah, iwm.
