Cov txheej txheem tsim khoom thiab txheej txheem ntawm PTC rhaub rau cov khoom siv

Cov txheej txheem tsim khoom thiab txheej txheem ntawm PTC rhaub rau cov khoom siv

1, Cov khoom xyaw

Tam sim no, feem ntau ntawm cov noodle manufacturers hauv Suav teb siv cov khoom-theem synthesis technology. Cov ntaub ntawv raw siv xws li BaCO3, Lub purity ntawm hmoov xws li SrCO3, Pb3O4, TiO2, Nb2O5, MnCO3, SiO2, thiab lwm yam. yuav tsum siab tshaj 99.5%. Lub purity ntawm raw cov ntaub ntawv, ntau yam thiab cov ntsiab lus ntawm impurities muaj, thiab cov tshuaj lom neeg kev ua si ntawm raw cov ntaub ntawv tag nrho muaj ib tug tseem ceeb cuam tshuam rau lub functionality ntawm lub kawg PTC khoom. Qhov tseeb ntawm cov khoom xyaw kuj muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov khoom.

2, Pob zeb kev puas tsuaj, tshem tawm dej

Ntsuas ntau cov khoom siv raw hmoov, sib tsoo pob, thiab dej ntshiab rau hauv lub pob zeb rau pob milling thiab kev puas tsuaj, thiab sib tov sib npaug. Cov khoom siv raw tom qab lub pob zeb tuaj yeem muab tso rau hauv qhov cub kom qhuav, lossis cov txheej txheem xws li kev pom, kev sib cais centrifugal, thiab lub tshuab nqus tsev tuaj yeem siv los tshem tawm cov dej ua ntej ziab.

3, Khoom theem synthesis

Cov theem khoom sib txuas, tseem hu ua pre firing, koom nrog muab cov khoom sib xyaw ua ke rau hauv qhov cub kub kub rau cov tshuaj tiv thaiv los tsim cov tshuaj sib xyaw ua ke. Cov qauv dav dav rau cov khoom siv tuaj yeem sau tau raws li (Bax, ...), Sry, Pbz)TiO3, Ntawm lawv, x + y + z =1, qhov kub rau cov khoom sib txuas yog xaiv ntawm 1000 ~ 1250 degree raws li cov khoom siv thiab qhov sib piv, thiab lub sijhawm rwb thaiv tsev yog 2-4 teev.

4, Secondary pob milling

Tom qab cov khoom sib txuas ua ke, cov khoom siv agglomerates thiab muaj qee qhov kev loj hlob ntawm cov nplej, uas yuav tsum tau pob milling los rhuav tshem thiab pab txhawb kev tua. Cov txheej txheem ntawm ob lub pob milling yog zoo ib yam li cov pre-synthesis pob milling.

5, tsim

PTC cov ntaub ntawv tuaj yeem ua rau ntau yam, xws li puag ncig, square, honeycomb, thiab lwm yam. Cov ntawv zoo li cov ntsiab lus yog tsim los ntawm cov xovxwm qhuav, thiab PVA tov haum rau kev nplaum yog ntxiv rau hauv cov khoom. Tom qab ntawd daim ntawv yog granulated los ntawm sieving los yog tshuaj tsuag kom qhuav, thiab ces tsim los ntawm nias rau ntawm lub punch. Honeycomb sab saum toj cov tswv cuab yog tsim los ntawm cov txheej txheem extrusion.

6, Hlawv rau hauv

Muab cov khoom tsim tawm mus rau hauv qhov cub kub kub, thiab raws li qhov tsim nyog tua hluav taws, hlawv cov khoom siv hluav taws xob semiconductor nrog cov yam ntxwv ntawm PTC. Qhov hluav taws xob nkhaus thiab hluav taws xob hluav taws xob muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm cov khoom, thiab kev tswj nruj yog tsim nyog rau kev tsim khoom los txhim kho cov khoom ua haujlwm thiab tawm los.
