Calcium phosphate

Tribasic phosphoric acid foomamka la saddex nooc oo ah calcium cusbada. Tani calcium hydrogen CaHPO4 phosphate, calcium dihydrogen phosphate Ca (H2PO4) 2 iyo orthophosphate, ama phosphate calcium, kuwaas oo caanaha la siiyo by: Ca3 (PO4) 2. cusbo Tani waa walax imanba, xaaladaha caadiga ah waa adag ah, iyo baas dareere (dhalaalayaa) heerkulka a of 1200 C. cufnaanta The si siman u 2,81 g / cm³, cufka gaws - 310,2 g / jirjirroolaha. phosphate Calcium waa liidata L. biyo, at 20 ° C jajabka tiro ka mid ah kama badna 0,0025%. Si ka duwan inta badan xarumaha kale, heerka ay milmi hoos ula sii kordhaya heerkulka. Sidaas darteed, kululaynta cusbo this waa inay awoodaan inay u sameeyaan kayd.

phosphate Calcium waa crystalline walax cad in uu yahay qayb ka mid ah macdanta apatite (iska fasalka ee phosphates ka kooban ilaa 56% Cao oo ku saabsan 41% P2O5), phosphorite (ururkii buunshada ama cufan ee apatite ay ku jiraan in ka badan 18% P2O5) iyo hydroxyapatite (qayb weyn ee lafta dadka iyo xoolaha). Waannu caddayn asal ah kayd qaar ka mid ah saxarada ama xayawaanka dhintay. beeraha kale (tusaale ahaan, in badaha qadiimiga ah) oo lagu sameeyay ay sabab u tahay nolosha "fosforobaktery". Laakiin meelaha qaar, lacag dhigaal ah ee macdanta waxa ay kala yihiin asal Gaarna macdanta. Oo kulligoodna waxaa lagu ballaaran qaybiyey ee dabiiciga ah iyo waxaa loo isticmaalaa in dhaqaalaha dalka.

Apatite waa wax a ceeriin for fosfooraska, bacriminta phosphate iyo phosphoric acid, iyo sidoo kale loo isticmaalaa in metallurgy ferrous cuntrooyinka in wax soo saarka ee dhalooyinka iyo dhoobada. macdanta dabiiciga ah kuwo dildillaaca phosphate asal ahaan kala duwan, laakiin si ka badan ku aasan, waxay waxaa loo isticmaalaa kobcinta dheeraad ah iyo wax soo saarka ee Bacriminta phosphate. Kaydka phosphorites iyo apatites waxaa ka mid ah muhiimadda ugu weyn ee beeraha, tan iyo ma aha oo kaliya loo isticmaalo in lagu soo saaro Bacriminta, laakiin sidoo kale sida il calcium quudinta shimbiraha ama xayawaanka ah: calafka calcium phosphate soo saaray si waafaqsan GOST 23999-80.

imanba Macdanta - apatite - waxaa loo isticmaalaa in ka badan labaatan geedi socodka saarka. Its isticmaalo wax soo saarka ee abrasives, dhalooyinka iyo dhoobada, iyo sidoo kale soo saara acid phosphoric lacag la'aan ah iyo fosfooraska. soo baxa Geedi sida uu nidaamka: 3SiO2 + Ca3 (PO4) 2 + 5C → 3CaSiO3 + 5CO + 2p. walax Tan waxaa sidoo kale sheegtay in warshadaha cuntada, la heli karo sida E341 daro cuntada sida ay GOST P 53945-2010, halkaas oo, ay la socdaan 1- iyo 2-bedelay cusbada ee phosphoric acid ka mid ah phosphate calcium. diyaarinta alaabta this ku lug leedahay shuruudo adag for feedstock ah. In wax soo saarka ee lagu daro cuntada la isticmaalayo phosphoric acid fasalka A iyadoo la raacayo GOST 10678-76, hydroxide calcium sida ay GOST 9262-77 iyo kiimikaad aloosnayd aan nuurad lahayn sida ay GOST 8253-79.

Macdanta kooban phosphate calcium, kaalin muhiim ah ee jirka aadanaha. Hydroxyapatite matali karaan by caanaha 3Sa3 (PO4) 3 • Ca (OH) 2. Waa qayb ugu weyn ee wax dhismaha iyo lafaha aadanaha. qayb macdanta ah ee dhaldhalaalka qaab fluorapatite ah. Shuruudaha looga baahan yahay maalin walba for waaweyn iyo fosfooraska, waa in kala duwan ee ka 800 si 1500 mg. Inta lagu guda jiro dheef xeryahooda fosfooraska ee jirka aadanaha jawaab beerka iyo nidaaminaya this hormoonnada habka iyo vitamin D. cudurada kala duwan ee lafaha iyo ilkaha horumariyay deficiency ah fosfooraska ee jirka. phosphate calcium ka timaadaa cuntada, xoojisaa ilkaha iyo lafaha, iyo isku dhafan oo macdano kale taageera nidaamka wadnaha iyo, ka hortagtaa kansarka mindhicirka, ayaa nidaaminaya shaqo dareemayaasha, ku lug leh dhismaha collagen, waxay ka caawisaa kolestaroolka hoose. phosphates waxaa ka soo jeeda saxarada, kaadida iyo maalin sii daayay oo ku saabsan 4 g of cusbada acid phosphoric.

Ilaha ugu waaweyn ee calcium phosphate in aadanaha - caanaha iyo waxyaabaha caanaha lo'da alaabta, cereals, casiirka deyr leh, cheese, ariga ee caanaha, salmon, sardines iyo ansjos. In si liidata L. biyo waa phosphate calcium ee-fiirsashada sare ee caanaha, tan iyo markii ay jirto a nidaamka Kolloidol qaab micelles - Qurub of core beelaya aad u yar, kaas oo la hareereeyey by taagoo dareeraha iyo adsorbed udhigo. Waxaa ka mid ahaa in casein caanaha, more hufan, caseinate calcium, taas oo la xidhiidha phosphoproteins, tan iyo markii ay ka kooban tahay koox phosphate ah. Si kastaba ha ahaatee, khubarada ku talinaynaa in ay ka fogaadaan xad dhaaf ah phosphate calcium, gaar ahaan qaab cuntooyinka iyo supplements deyr leh, haddii uu qofku qabo mid ka mid ah cudurada soo socda: parathyroid, dhagxaan kellida ama inta lagu jiro daaweynta ka socda oo ka kooban antibiotics tetracycline.
