Ultra-nplua zeb txhawb kev txhim kho ntawm Silicon Carbide

Silicon carbide micropowder yog dav siv nyob rau hauv cov ntaub ntawv refractory, hnav-resistant flooring, ua npuas ncauj ceramics, tshwj xeeb coatings, anti-corrosion xim, de-flowing ib puag ncig tiv thaiv thiab lwm yam lag luam. Tib lub sijhawm, silicon carbide ultra-fine micro-powder yog cov khoom siv zoo tshaj plaws rau kev tsim cov SiC ceramics, thiab silicon carbide micro-powder kuj yog cov khoom siv engineering rau kev lag luam hnub ci photovoltaic, kev lag luam semiconductor, thiab piezoelectric siv lead ua kev lag luam. Nyob rau hauv lub era ntawm underdeveloped technology, nws tsis yog yooj yim los siv silicon carbide micropowder. Tam sim no peb muaj superfine zeb, yog li peb muaj kev txhawb nqa zoo.

Tam sim no, domestic silicon carbide micropowder feem ntau yog dub silicon carbide micropowder thiab ntsuab silicon carbide micropowder. Cov qauv tseem ceeb ntawm silicon carbide micropowder yog: lub teb chaws tus qauv, Japanese tus qauv, thiab cov qauv European. Kev ua lag luam yog dominated los ntawm lub teb chaws thiab Japanese cov qauv, thaum exports mas yog Japanese. Ultra-nplua zeb zoo tagnrho rau kev sib tsoo silicon carbide hmoov.

Kev tsim cov txheej txheem ntawm silicon carbide micropowder: (1) noj cov khoom siv silicon carbide raw khoom, crushed los ntawm crusher, thiab sieved rau silicon carbide hais tsis ntau tshaj 5 hli, thiab ces shaping nws mus rau ib tug silicon carbide particle tsis ntau tshaj 2 hli los ntawm kev siv ib tug tshuab shaping. Thiab nyob rau hauv lub oval hais tus account rau ntau tshaj 80%, thiab ces pickling thiab tshem tawm impurities thiab ziab; (2) pulverizing cov qhuav silicon carbide hais rau hauv silicon carbide hmoov uas muaj d50 = 9.5-11.5 μm los ntawm ib lub zeb. Thaum pulverizing, lub ntsiab tam sim no ntawm lub zeb yog teem rau 65-75A, kiv cua ntws yog teem rau 40-50m3 / min, thiab qhov ceev ntawm lub analyzer yog 400-600 rpm. (3) Tom qab ntawd cov carbonization yog ua los ntawm vortex flow classifier. Thaum cov hmoov silicon raug cais thiab cais tawm, tus nqi ntws ntawm tus kiv cua ntawm vortex flow classifier yog 25-43 m3 / min, qhov ceev ntawm lub log faib yog 2600--3300 rpm, thiab cov khoom tiav A nrog cov particle loj. ds94 = 6.5-5.5 μm raug cais tawm ntawm qhov chaw nres nkoj. Lub qhov ncauj cua daj cua dub tau muab faib ua cov khoom ua tiav ntawm ds94 ≤ 5.5μm; (4) Cov khoom lag luam semi-tiav sib cais los ntawm vortex flow classifier cyclone raug cais ntxiv los ntawm impeller hom airflow classifier, thiab kiv cua ntws ntawm impeller hom cua classifier yog cais. 25-10m3 / min, grading log ceev yog 1300--1700 rev / min, thiab cov granules raug cais tawm ntawm qhov chaw nres nkoj. Ds94 = B 4.5-3.0μm tiav lawm, lub cua daj cua dub inlet yog sib cais los ntawm cov khoom.

Vim yog cov yam ntxwv ntawm cov txheej txheem ntawm silicon carbide micropowder ntau lawm, qhov kev thov nce ntxiv rau silicon carbide micropowder yuav coj txoj hauv kev loj hlob mus rau pulverizer thiab vibrating screen kev lag luam, thiab cov kev xav tau ntawm kev ua tau zoo yog qhov tshwj xeeb.
