Kalsiyum karbonat, kristal formuna g\u00f6re k\u00fcbik, i\u011f, zincir, k\u00fcresel, pul, i\u011fne vb. olarak ayr\u0131labilir. Kalsiyum karbonat\u0131n farkl\u0131 formlar\u0131n\u0131n farkl\u0131 uygulama alanlar\u0131 ve i\u015flevleri vard\u0131r.<\/p>\n
Bu nedenle, \u00e7e\u015fitli end\u00fcstrilerin farkl\u0131 kristal kalsiyum karbonat \u00fcr\u00fcnlerine olan ihtiya\u00e7lar\u0131n\u0131 kar\u015f\u0131lamak i\u00e7in, kalsiyum karbonat\u0131n kristalle\u015fme s\u00fcrecini kontrol etmek ve farkl\u0131 kristal formlar\u0131na sahip \u00fcr\u00fcnler \u00fcretmek i\u00e7in kristal form kontrol y\u00f6ntemlerinin kullan\u0131lmas\u0131 gerekir.<\/p>\n
1. K\u00fcbik kalsiyum karbonat<\/p>\n
K\u00fcbik olarak adland\u0131r\u0131lan, kristalleri transmisyon elektron mikroskobu alt\u0131nda k\u00fcpler halinde g\u00f6sterilen kalsiyum karbonat\u0131 ifade eder.<\/p>\n
End\u00fcstriyel \u00fcretim, d\u00fc\u015f\u00fck s\u0131cakl\u0131k teknolojisi kullan\u0131larak sodyum kalsiyum karbonat \u00fcretme s\u00fcrecinde, herhangi bir kristal form kontrol maddesi eklenmeden, karbonizasyon s\u0131cakl\u0131\u011f\u0131n\u0131n kontrol edilmesiyle k\u00fcbik kalsiyum karbonat \u00fcr\u00fcn\u00fc elde edilebilece\u011fini g\u00f6stermektedir. \u00c7\u00f6keltilmi\u015f kalsiyum karbonat\u0131n kristal yap\u0131s\u0131 b\u00fcy\u00fck \u00f6l\u00e7\u00fcde olu\u015ftu\u011fu s\u0131cakl\u0131\u011fa ba\u011fl\u0131d\u0131r. Kristal \u00e7ekirde\u011finin olu\u015ftu\u011fu s\u0131cakl\u0131k 30\u00b0C’den d\u00fc\u015f\u00fck oldu\u011fu s\u00fcrece k\u00fcbik kalsiyum karbonata karbonize edilebilir.<\/p>\n
2. G\u00fcl \u015feklinde ve i\u011f \u015feklinde kalsiyum karbonat<\/p>\n
G\u00fcl \u015feklinde ve i\u011f \u015feklinde kalsiyum karbonat genellikle ka\u011f\u0131t yap\u0131m\u0131nda, kau\u00e7ukta, plastikte, kaplamada ve di\u011fer end\u00fcstrilerde, \u00f6zellikle sigara ka\u011f\u0131d\u0131n\u0131n yanma performans\u0131n\u0131 ve hava ge\u00e7irgenli\u011fini art\u0131rabilen y\u00fcksek kaliteli sigara ka\u011f\u0131d\u0131nda kullan\u0131l\u0131r.<\/p>\n
\u00dclkemde i\u011f \u015feklinde kalsiyum karbonat \u00fcretmenin ana y\u00f6ntemi \u015fudur: oda s\u0131cakl\u0131\u011f\u0131nda, kire\u00e7 s\u00fct\u00fc konsantrasyonu yakla\u015f\u0131k %35’te (a\u011f\u0131rl\u0131k oran\u0131) kontrol edilir ve karbonizasyon i\u00e7in reakt\u00f6re %30-40 (hacim oran\u0131) CO2 kar\u0131\u015f\u0131m gaz\u0131 verilir. Karbonizasyon i\u015flemi oda s\u0131cakl\u0131\u011f\u0131nda ger\u00e7ekle\u015ftirilir. Ekzotermik reaksiyon nedeniyle reakt\u00f6r\u00fcn s\u0131cakl\u0131\u011f\u0131 oda s\u0131cakl\u0131\u011f\u0131ndan yakla\u015f\u0131k 75\u00b0C’ye y\u00fckselir. \u00dcr\u00fcn\u00fcn morfolojisi esas olarak i\u011f \u015feklindedir ve par\u00e7ac\u0131k boyutu genellikle birka\u00e7 mikrondur.<\/p>\n
3. Zincir kalsiyum karbonat<\/p>\n
Zincir \u015feklinde ultra ince kalsiyum karbonat, birbirine ba\u011fl\u0131 birka\u00e7 ila d\u00fczinelerce ince kalsiyum karbonat taneci\u011finden olu\u015fur ve bir zincir yap\u0131s\u0131na sahiptir. Farkl\u0131 sentez ko\u015fullar\u0131yla farkl\u0131 par\u00e7ac\u0131k boyutlar\u0131 ve en boy oranlar\u0131 olacakt\u0131r.
\nZincir \u015feklindeki ultra ince kalsiyum karbonat, do\u011fal kau\u00e7uk ve sentetik kau\u00e7uk \u00fczerinde m\u00fckemmel bir takviye etkisine sahiptir. Takviye dolgu maddesi olarak, karbon siyah\u0131 veya beyaz karbon siyah\u0131n\u0131n yerini k\u0131smen alabilir ve \u00fcretim maliyetlerini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde azaltabilir. Ek olarak, zincir benzeri ultra ince kalsiyum karbonat, kaplama, ka\u011f\u0131t yap\u0131m\u0131 ve plastik end\u00fcstrilerinde katk\u0131 maddesi olarak kullan\u0131l\u0131r, m\u00fckemmel performans g\u00f6sterir ve geni\u015f uygulama beklentilerine sahiptir.<\/p>\n
Zincir benzeri kalsiyum karbonat\u0131n sentezi hakk\u0131nda bir\u00e7ok rapor vard\u0131r, ancak genel y\u00f6ntem, Ca (OH) 2 s\u00fcspansiyonu karbonizasyon i\u015fleminin yar\u0131s\u0131nda viskoz bir kolloidal em\u00fclsiyon haline geldi\u011finde kristal \u00e7ekirde\u011finin b\u00fcy\u00fcmesini kontrol etmek i\u00e7in bir kristal \u015fekil kontrol\u00f6r\u00fc eklemektir. Ana kristal \u015fekil kontrol\u00f6rleri magnezyum tuzlar\u0131, potasyum tuzlar\u0131, sodyum polifosfatlar, suda \u00e7\u00f6z\u00fcn\u00fcr metal tuzlar\u0131 ve \u015felatlama ajanlar\u0131d\u0131r.<\/p>\n
4. K\u00fcresel kalsiyum karbonat<\/p>\n
\u0130yi p\u00fcr\u00fczs\u00fczl\u00fc\u011f\u00fc, ak\u0131\u015fkanl\u0131\u011f\u0131, da\u011f\u0131labilirli\u011fi ve a\u015f\u0131nma direnci nedeniyle k\u00fcresel nano kalsiyum karbonat kau\u00e7uk, kaplama boyas\u0131, m\u00fcrekkep, ila\u00e7, di\u015f macunu ve kozmetiklerde yayg\u0131n olarak kullan\u0131l\u0131r.<\/p>\n
K\u00fcresel kalsiyum karbonat genellikle kalsiyum tuzu ve karbonat\u0131n konsantre alkali bir \u00e7\u00f6zeltide d\u00fc\u015f\u00fck s\u0131cakl\u0131kta reaksiyonuyla haz\u0131rlan\u0131r. Ana kristal \u015fekil kontrol\u00f6rleri magnezyum tuzlar\u0131, potasyum tuzlar\u0131 ve sodyum polifosfatt\u0131r.<\/p>\n
5. Pul kalsiyum karbonat<\/p>\n
Pul kalsiyum karbonat ka\u011f\u0131t yap\u0131m end\u00fcstrisi i\u00e7in uygundur ve m\u00fckemmel m\u00fcrekkep emilimi, beyazl\u0131k, bask\u0131 yap\u0131labilirlik ve p\u00fcr\u00fczs\u00fczl\u00fc\u011fe sahip ka\u011f\u0131t \u00fcretebilir. Dolgu maddesi ve takviye maddesi olarak pul kalsiyum karbonat, al\u0131\u015f\u0131lmad\u0131k d\u00fczenlemesi nedeniyle kar\u0131\u015f\u0131mda y\u00fcksek p\u00fcr\u00fczs\u00fczl\u00fck, parlakl\u0131k, \u00f6zdiren\u00e7 ve elastiklik katsay\u0131s\u0131na sahiptir.<\/p>\n
Pul nano kalsiyum karbonat kaplamal\u0131 ka\u011f\u0131t pigmenti i\u00e7in kullan\u0131ld\u0131\u011f\u0131nda iyi ak\u0131\u015fkanl\u0131k ve da\u011f\u0131labilirlik g\u00f6sterir ve s\u0131radan i\u011f PCC hafif kalsiyum karbonattan daha iyi parlakl\u0131k ve p\u00fcr\u00fczs\u00fczl\u00fc\u011fe sahiptir.<\/p>\n
6. \u0130\u011fne kalsiyum karbonat<\/p>\n
\u0130\u011fne kalsiyum karbonat b\u00fcy\u00fck bir en boy oran\u0131na sahiptir. Plastikler i\u00e7in dolgu maddesi olarak kullan\u0131ld\u0131\u011f\u0131nda plastiklerin darbe direncini ve e\u011filme mukavemetini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde iyile\u015ftirebilir; kau\u00e7ukta kullan\u0131ld\u0131\u011f\u0131nda takviye etkisi daha belirgindir.<\/p>\n","protected":false},"excerpt":{"rendered":"
