Amathayela e-Silicon Carbide Ceramic
Iklanyelwe ukumelana nezinselele zokusebenza ngokweqile,amathayili we-silicon carbideisiphenduke into esetshenziswayo yokuma ezimbonini ezidinga ukuvikelwa kokugqokwa okungayekethisi. I-microstructure yayo eyingqayizivele iletha ukusebenza okuyingqayizivele ku:
- Izindawo zokuhuzuka okukhulu eziphethe ama-coarse particulate (~ 5mm)
- Ukuhlukaniswa okunomthelela omkhulu kanye nezinhlelo zokususa amanzi
- Izokuthutha zemidiya ezonakalisayo ekucutshungulweni kwamakhorali nasezitshalweni zamakhemikhali
Kusukela kubahambisi be-steel mill slag kuya ebusweni be-mechanical seal ekukhiqizeni impahla eluhlaza,amathayili we-silicon carbideizingxenye zisebenza njengezikhali zempi ezinobunjiniyela - zivikela ngokunembile izindawo zokuguga ezibucayi kuyilapho zigcina ukuqina kohlangothi ngaphansi kwengcindezi eqhubekayo.
Njengoba kukhula isidingo samathayela e-silicon carbide, amalayini, namapayipi kuwo wonke amaketanga okucubungula amaminerali, abathengi abaqaphelayo kufanele babeke phambili lezi zilinganiso:
1. Ukwakhiwa Okuqhutshwa Ngamagugu
Inhlanganisela yethu yemvelaphi yaseJalimane ihlolwa kaningi ukuguguleka, ifinyelela amazinga okulahleka kwempahla angaphansi kuka-0.86㎝³ - ubufakazi bobuqotho be-matrix ye-silicon carbide tiles.
2. Iphrothokholi Yokuqinisekisa Ukuqina
Amathayela e-silicon carbide enza imephu ye-triaxial stress, ebonisa ubulukhuni be-Mohs obusha obungu-14.55±4.5 ngokuhlukahluka okungu-≤2% MOR kuwo wonke amaqoqo okukhiqiza.
3. Ukulawula Ukunemba Kokuminyana
I-substanding sintering idala ubungozi besakhiwo. Inqubo yethu yamathayela e-silicon carbide igcina ukuminyana okungu-3.03±0.05g/㎝³ ngokusebenzisa isibopho sokusabela esisizwa yingcindezi, sisusa izikhala ezingaphansi komhlaba.
4. Ukuphelela KweJiyomethri
▸ I-laser-verified surface flatness (＜0.02mm/m²)
▸ Ukuvumelana kwerediyasi yonqenqema (0.5±0.1mm)
▸ Isitifiketi esingu-100% se-crack/esingenazimbotshana
I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
