Ipayipi elivikela ukuguguleka elinomugqa we-silicon carbide ceramic
Amapayipi amelana nokuguguleka kwe-silicon carbide angamapayipi enziwe kakhulu nge-silicon carbide futhi anezicelo eziningi emikhakheni eminingi. Ukuncintisana kwawo okuyinhloko kungokulandelayo:
(1) Uguquko Lokuphila
Uma kuthuthwa izinto ezihudulayo ezifana nomlotha wamalahle kanye nodaka, isikhathi sokuphila siphindwe kayishumi kunesezinsimbi, okunciphisa ukulahlekelwa okuvamile kokushintshwa kanye nesikhathi sokungasebenzi.
（2）Izimo zokusebenza ezimbi kakhulu zivamile
Ukusebenza okuzinzile kusuka ku--50 ℃ kuya ku-1600 ℃, ngokumelana nokushaqeka kokushisa ukuvimbela ukuqhekeka, kufanelekile ezimweni zokushisa okuphezulu njengemboni yensimbi kanye namakhemikhali.
（3） Ukusetshenziswa okuningi kwezinto ezisetshenziswayo
Xazulula izinkinga ezine ezinkulu zokuguga, ukugqwala, izinga lokushisa eliphezulu, kanye nokuvimbela ukuqhuma ngasikhathi sinye.
（4）Ilula futhi iyonga amandla
Umklamo olula unciphisa izindleko zokuhamba nokufakwa, kanti i-coefficient ephansi yokungqubuzana inciphisa ukusetshenziswa kwamandla okupompa.
Inzuzo yokuchoboza yamapayipi e-silicon carbide uma iqhathaniswa nezinto zendabuko:
| Ubukhulu bokusebenza | Ipayipi le-silicon carbide | Amapayipi ensimbi/epulasitiki |
| Ukumelana nokugqoka | Ukuqina okungu-2800HV (okuphindwe kahlanu kunokwensimbi), isikhathi sokuphila isikhathi eside ngokuphindwe kayishumi kunokwamapayipi angewona awensimbi | Insimbi ivame ukuguguleka, kuyilapho ipulasitiki inobunzima obuphansi (PE<1 HV) |
| Izinga lokushisa eliphezulu ukumelana | Imelana namazinga okushisa aphezulu angu-1600 ℃ kanye nokushaqeka kokushisa (i-coefficient yokwanda kokushisa okungu-4 × 10 ⁻⁶/℃) | Insimbi engagqwali ithambekele ekushiseni okuphezulu, kuyilapho amapulasitiki enokumelana nokushisa okungaphansi kuka-80 ℃ |
| Ukumelana nokugqwala | Ayimelani nama-asidi aqinile (i-asidi ye-sulfuric egxilile), izisekelo eziqinile, kanye nokugqwala kwensimbi encibilikisiwe | Insimbi engagqwali ibhekana nokugqwala lapho ivezwa kuma-ion e-chloride, kuyilapho ipulasitiki inokumelana okulinganiselwe kwamakhemikhali |
| Ilula | Ubuningi obungu-3.0~3.14 g/cm³ (bulula ngo-60% kunensimbi) | Amapayipi ensimbi makhulu futhi anezindleko eziphezulu zokufaka |
| Ukwandiswa Kokusebenza | Ukuhlanzeka kwe-anti-static (ukuqhuba okubuthakathaka), izinga le-semiconductor | Izinsimbi zidinga ukwelashwa okwengeziwe ukuze kuvinjelwe ukuqhuma, kuyilapho ipulasitiki ithambekele ekungcoleni |
Ngamafuphi, cishe asikho esinye isisombululo semipayipi ye-silicon carbide lapho kuthuthwa izinto ezibola kakhulu nezimelana nokuguguleka njenge-slurries ene-asidi kanye nomlotha wegesi yoketshezi olushisayo oshisa kakhulu.
Uma unemibuzo, sicela ukhululeke ukuxhumana nathi nganoma yisiphi isikhathi.
I-Shandong Zhongpeng Special Ceramics Co., Ltd ingenye yezixazululo ezinkulu zezinto ezintsha ze-silicon carbide ceramic eShayina. I-SiC technical ceramic: Ubulukhuni bukaMoh buyi-9 (ubulukhuni bukaMoh obuyi-13), bunokumelana okuhle kakhulu nokuguguleka nokugqwala, ukumelana okuhle kakhulu - ukumelana nokugqwala kanye nokulwa nokubola. Impilo yesevisi yomkhiqizo we-SiC ide ngokuphindwe ka-4 kuya ku-5 kune-92% ye-alumina material. I-MOR ye-RBSiC iphindwe ka-5 kuya ku-7 kune-SNBSC, ingasetshenziswa ezimweni eziyinkimbinkimbi kakhulu. Inqubo yokucaphuna iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ayilingani. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisela izinhliziyo zethu emphakathini.
