Izingxenye ze-ceramic ze-silicon carbide ezinembile, ngenxa yezakhiwo zazo ezibonakalayo namakhemikhali ezivelele, seziyinto eyinhloko emkhakheni wokukhiqiza{0}}okunemba okuphezulu. Badlala indima ebalulekile ekusikeni-imishini esemaphethelweni efana nama-semiconductors kanye nemishini ye-lithography.
Ama-ceramics e-silicon carbide ikakhulukazi anezakhiwo ezinjengokumelana ne-oxidation, ukuqhutshwa kukagesi, ubulukhuni obuphezulu, kanye nokuhamba okuphezulu kwe-thermal.
Incazelo Yemikhiqizo
I-silicon carbide ceramics iwuhlobo lwe-ceramic ekhethekile eyenziwe ngezinto ezingavuthiwe ze-silicon carbide ngezinqubo ezahlukahlukene. Ake sibheke izici ezinhle kakhulu ze-silicon carbide ceramics. Ama-ceramics e-silicon carbide ikakhulukazi anezakhiwo ezinjengokumelana ne-oxidation, ukuqhutshwa kukagesi, ubulukhuni obuphezulu, kanye nokuhamba okuphezulu kwe-thermal.
(1) Ukumelana ne-oxidation: I-silicon carbide ceramics inokumelana ne-oxidation okubi emazingeni okushisa asukela ku-800 kuya ku-1140 degrees Celsius, kodwa ibonisa ukumelana ne-oxidation okuhle kakhulu emazingeni okushisa aphakathi kuka-1140 no-1600 degrees Celsius. Ngaphezulu kwe-1750 degrees Celsius, ifilimu ye-oxide iyabhujiswa futhi ukumelana ne-oxidation kwehla kakhulu.
(2) I-electrical conductivity: I-silicon carbide ehlanzekile iyisivikeli, kodwa izitsha zobumba ze-silicon carbide ziqukethe ukungcola okuhlukahlukene, ngaleyo ndlela zinokusebenza okuthile kagesi.
(3) Ukuqina okuphezulu: Ukusebenza kokuqina kwe-silicon carbide ceramics kunqunywa yi-silicon carbide ngokwayo. Njengoba izinga lokushisa likhuphuka, ubulukhuni be-silicon carbide ceramics abunciphi.
(4) I-Thermal conductivity: Ezingeni lokushisa lasekamelweni, ukuqhutshwa kokushisa kwe-silicon carbide ceramics kuphezulu kakhulu.
{0}}Indandatho yokuvala esebenza kakhulu:Izingxenye zokuvala ze-silicon carbide zamaphampu amakhemikhali, amelana ne-asidi eqinile kanye nokugqwala kwe-alkali, okunokwehliswa okungama-50% kwezinga lokuhluleka.
Amabhere nemihlahlandlela:Amabheringi{0}}omshini onesivinini esiphezulu ane-coefficient yokungqubuzana ephansi njengo-0.001, athuthukisa ukugcinwa kokunemba.
Imilomo namathuluzi okusika:Izimbobo ezishisayo-ezicindezelwe ze-SiC ezicindezelwe esihlabathini, ezinokumelana nokuguga okuphindwe izikhathi ezingu-20 kunezingxenye zensimbi.
Ukubonisa Imikhiqizo
kungani ukhethe thina
Impendulo esheshayo Imikhiqizo enezindleko eziphezulu Imikhiqizo enezindleko eziphezulu zokusebenza
kungani ukhethe imikhiqizo yethu
1. 20 iminyaka yesipiliyoni ku-cast iron plate, ukuqinisekiswa kwekhwalithi, ukulethwa ngesikhathi
2. Umshini ophelele kanye nemishini yokuhlola ingahlinzeka ngokuqondile izingxenye eziqediwe futhi ihlangabezane nezidingo zokuhlola zamakhasimende
3. Inamalungelo azimele okungenisa nokuthekelisa futhi ingathumela imikhiqizo kuzo zonke izingxenye zomhlaba
Amashadi ashisayo: izingxenye eziqondile ze-silicon carbide ceramic, i-China precision silicon carbide ceramic izingxenye abakhiqizi, abahlinzeki, imboni
