Ceramic cua sov phaj
Far-infrared cua sov tshuab yog lub zog txuag hluav taws xob uas tau pib txhawb nqa thaum xyoo 1970s. Txhawm rau siv cov thev naus laus zis no los txhim kho cov cua sov kom zoo, nws yog ib qho tseem ceeb los txhim kho lub peev xwm nqus ntawm cov khoom siv hluav taws xob rau hluav taws xob kom cov molecular vibration wavelength phim lub wavelength ntawm far-infrared spectrum. Yog li ntawd, cov khoom siv hluav taws xob tsim nyog yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm cov khoom yuav tsum tau ua kom sov, thiab cov khoom siv hluav taws xob sib txawv yuav tsum tau siv tib lub sijhawm, thiab qhov chaw ntawm lub cev cua sov yuav tsum tau txhim kho. Tam sim no, txoj kev cua sov no tau siv dav hauv cov tshuab yas. Cov khoom xws li infrared cua sov cib los yog cua sov cib hluav taws xob cua sov phaj yog luv luv rau cov khoom no. Tom qab kev txhim kho thev naus laus zis, kev txuag hluav taws xob yog qhov tseem ceeb, uas tuaj yeem txo qis kev siv hluav taws xob thiab txuag hluav taws xob.
Lub embedded ceramic far-infrared radiating lub caij yog ua los ntawm ib tug siab emissivity glaze txheej, ib tug ceramic nrog zoo thermal shock kev ua tau zoo raws li lub substrate, thiab high-zoo hluav taws xob cua sov hlau sintered nyob rau hauv ib lub sij hawm. Lawv compositions yog raws li nram no:
1.Matrix: Nws yog tsim los ntawm cov khoom siv ceramic nrog zoo thermal shock;
2. Thaum tshav kub kub tiam: ua los ntawm high-zoo nickel-chromium alloy hlau;
3.Glaze txheej: Nws yog tsim los ntawm cov hlau oxide raw cov ntaub ntawv nrog kev ua haujlwm zoo ntawm cov hluav taws xob sab nraud thiab muab cov khoom siv tsim nyog los txhim kho cov hluav taws xob siv hluav taws xob thiab txhim kho qhov hloov kho ntawm glaze.
Piv nrog rau cov txheej txheem cua sov ib txwm muaj xws li chav dej, cua kub thiab ua haujlwm, cov cua kub nyob deb infrared muaj ntau yam zoo xws li cua sov ceev, zoo zoo ntawm cov khoom tshiab, cov khoom siv me me, cov nqi qis thiab cov cua sov ua haujlwm zoo. Siv nws tsis siv hluav taws xob cua sov, nws lub zog txuag hluav taws xob yog qhov zoo tshaj plaws, feem ntau txog 30% ntawm hluav taws xob tuaj yeem txuag tau, thiab txawm tias mus txog 60% txog 70% hauv qee lub sijhawm. Vim li no, lub tshuab no tau siv dav hauv kev ua haujlwm sib txawv xws li cua sov, melting, ziab, shaping, noj, thiab kho ntau yam khoom los yog cov ntaub ntawv xws li xim, yas, zaub mov, tshuaj, ntoo, tawv, textiles, tshuaj yej. , haus luam yeeb, thiab lwm yam Nws yog feem ntau ntseeg hais tias cov cua sov thiab ziab ntawm ntoo, tawv, xim thiab lwm yam organic tshuaj, polymers thiab dej-muaj tshuaj muaj cov nyhuv tseem ceeb. Qee lub sijhawm, cov nyhuv ntawm cov thev naus laus zis no thiab aluminium silicate refractory fiber rwb thaiv tsev cov ntaub ntawv hauv tib lub cub tawg yog qhov zoo heev.
