Zirconia hlaws dai, zirconium silicate, thiab zirconium-aluminium composite cov ntaub ntawv yog tag nrho cov kev sib tsoo xov xwm, thiab lub khw muaj ntau lub npe rau zirconia hlaws dai los yog cov khoom zoo sib xws. Cov muaj pes tsawg leeg thiab cov qauv tshuaj kawg ntawm cov hlaws tiav tau piav qhia hauv qab no raws li cov qauv kev lag luam thoob ntiaj teb.
Zirconia hlaws, tseem hu ua "TZP" zirconium hlaws, yog ua los ntawm micron thiab sub-nanoscale zirconia thiab yttrium oxide ua raw khoom. Lawv yog siv rau kev sib tsoo ntawm cov ntaub ntawv uas yuav tsum tau "zero pollution" thiab siab viscosity thiab siab hardness. thiab dispersion ntawm ib hom kev sib tsoo hlaws. Cov mis mos molecular ntawm zirconia yog ZrO2, thiab ntshiab zirconia feem ntau muaj nyob rau hauv peb hom, monoclinic (m-ZrO2), tetragonal (t-ZrO2), thiab tetragonal (c-ZrO2).
Peb cov ntaub ntawv no tuaj yeem hloov pauv mus rau ib leeg ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab muaj nyob rau hauv cov txheej txheem monoclinic hauv qab 1300 degree. Lub monoclinic crystal system tsis ruaj khov heev nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam vim yog cov qauv ntawm chav tsev cell nws tus kheej; Lub lattice qauv ntawm tetragonal siv lead ua system thiab tetragonal siv lead ua system yog qhov ruaj khov heev.
Zirconium silicate tuaj yeem suav tias yog cov khoom sib xyaw oxide, uas yog tsim los ntawm silicon oxide thiab zirconium oxide nyob rau hauv tib lub molar piv, thiab cov mis mos molecular yog ZrSiO.4. Qhov tshwj xeeb lub ntiajteb txawj nqus yog li 4.0kg/dm3, thiab Vickers hardness yog hais txog 1000kgf / mm2. Zirconium silicate hlaws daiFeem ntau siv vim lawv qhov nruab nrab ntom thiab hardness, zoo heev hnav tsis kam thiab pheej yig dua tus nqi zirconia hlaws.
Raws li cov hlaws phasing txheej txheem, nws muab faib ua ob hom: sintering thiab electrofusion. Cov hlaws dai sintered ua los ntawm zircon xuab zeb raws li cov ntaub ntawv raw yog xav txog hauv ib qho microstructure zoo ib yam. Lub tom kawg yog tsim los ntawm melting thiab sib tov zirconia hmoov thiab silica hmoov. Lub microstructure yog zirconia crystals thiab silica iav lub cev. Nyob rau tib lub sijhawm, nws kuj yog qhov tsis xws ntawm cov txheej txheem no uas cov kab noj hniav tsis tuaj yeem zam tau.
Vim muaj keeb kwm keeb kwm, ntau tus neeg yuam kev hu ua zirconium silicate hlaws dai zirconia hlaws, thiab hu rau lawv cov hlaws zirconium luv luv; tau kawg, qee tus neeg hu ua zirconia hlaws zirconium hlaws luv luv, thiab tsis meej pem tshwm sim.
Qhov tseeb, ob qho tib si zirconium silicate hlaws thiab zirconia hlaws yog cov khoom sib tsoo zoo, uas tau siv dav hauv kev tsim khoom. Zirconia hlaws yog tsuas yog siv rau ultra-fine sib tsoo thiab dispersion ntawm cov ntaub ntawv uas yuav tsum tau "zero pollution" thiab siab viscosity thiab siab hardness, xws li: hluav taws xob ceramics, sib nqus cov ntaub ntawv, zirconia, silicon oxide, zirconium silicate, titanium dioxide, tshuaj zaub mov, pigments. , dyes, inks, tshwj xeeb tshuaj industries. Zirconium silicate hlaws yog siv rau hauv number case, flexo ink, inkjet, xim muab tshuaj, khoom siv hluav taws xob, tshuaj, txheej, xim thiab lwm yam kev lag luam tshuaj.
Qhov zoo sib xws hauv daim ntawv thov teb ntawm ob ua rau nws nyuaj rau cov neeg yuav khoom. Qhov twg ntawm ob lub hlaws zoo dua thiab qhov twg yog tus nqi ntau dua. Tam sim no cia peb sib piv thiab sib txawv ntawm cov hauv qab no.
1. Qhov sib txawv ntawm cov tsos thiab kev ua tau zoo, zirconium silicate feem ntau yog daj-dawb, tsis ci, thiab opaque. Zirconium silicate hlaws dai yog ua los ntawm zirconium silicate hmoov, tus nqi kuj qis, xim yog lub teeb daj, thiab zirconium oxide hlaws yog dawb thiab ua los ntawm zirconium oxide hmoov. Zirconia hlaws muaj kev ua tau zoo dua li zirconium silicate hlaws thiab qis dua li zirconium silicate hlaws.
2. Hardness: Tsis muaj qhov sib txawv ntawm qhov hardness ntawm ob lub hlaws, ob qho tib si yog Mohs 9, uas tsis muaj teeb meem thaum sib tsoo cov ntaub ntawv feem ntau.
3. Ceev: Qhov ceev ntawm zirconium silicate hlaws dai yog 4.0, thiab qhov ceev ntawm zirconia hlaws yog 6.0. Piv txwv li, 95 zirconia hlaws dai xa mus rau zirconium hlaws muaj li 95 feem pua ntawm zirconium, qhov tshwj xeeb lub ntiajteb txawj nqus yog 6.0g / cm3, thiab qhov bulk ntom yog nyob rau hauv qhov tshwj xeeb gravity. Muab faib los ntawm 0.6 ntawm lub hauv paus, nws yog 3.6g/cm3, uas txhais tau hais tias 3.6 tons ntawm zirconium hlaws tuaj yeem muab tso rau hauv ib lub cubic ntim. Qhov ntom ntom ntawm 95 zirconia hlaws yog qhov loj dua piv rau lwm cov pob zeb ceramic, xws li cov pob alumina, zirconium aluminium pob, zirconium silicate npas, thiab lwm yam. Qhov loj dua qhov ntom ntom, cov hlaws ntau yog muab tso rau hauv cov xuab zeb zeb lossis pob zeb, thiab siab dua qhov sib tsoo efficiency. Vim tias qhov ntom ntom, kev sib tsoo ua haujlwm ntawm zirconia hlaws yog zoo dua li ntawm zirconium silicate hlaws, tab sis vim muaj qhov ntom ntom, nws tsis haum rau qee cov xuab zeb zeb, xws li cov xuab zeb ntsug. Lub sijhawm no, zirconium silicate hlaws dai tseem pom zoo.
4. Scope ntawm daim ntawv thov: Zirconium silicate hlaws dai yog tsuas yog siv nyob rau hauv ntsug xuab zeb mills uas tsis muaj kev sib hloov ceev, vim hais tias lawv toughness tsis zoo li cov zirconia hlaws dai, thiab cov hlaws dai tau yooj yim tawg thaum lub sij hawm sib tsoo high-speed. Zirconia yuav tsis muaj qhov teeb meem zoo li no, yog li nws feem ntau siv rau hauv cov xuab zeb kab rov tav.
5. Nqe: Qhov no yuav tsum muaj kev txhawj xeeb rau txhua tus. Tus nqi ntawm zirconium silicate hlaws yog feem ntau nyob ib ncig ntawm 50 yuan ib kilogram (raws li tus nqi tshwj xeeb), thaum tus nqi ntawm zirconia hlaws yog siab li 160 yuan (raws li tus nqi tshwj xeeb), uas kuj ua rau tus nqi ntawm zirconium silicate. hlaws ntau ntau dua li cov hlaws zirconia.
