Imigozi ya keramike ya silikoni

Umwambaro urinda kwangirika kwa silicon carbide

Imiterere y'imirongo irwanya kwambara ya Silicon Carbide (SiC):

（1） Igishushanyo mbonera cy'inzira y'amazi igenda neza

Imiterere yoroshye kandi yoroshye kuva aho yinjira kugera aho asohokera igabanya ubukana bw'amazi atemba, bigatuma imiyoboro ya SiC ihuzwa n'inganda zitandukanye.

（2）Uburyo bwo gukora atome ihanitse

Uburyo bw'amazi buhinduka ibitonyanga bito binyuze mu kugongana kw'imirongo ya SiC, aho ubuso bwa helikopta bugenda bugabanuka buhoro buhoro, bigatuma habaho gukwirakwira kw'imiyoboro imwe.

（3）Imiterere mito kandi idafite uruziga

Umuyoboro ugororotse kandi udafite ishingiro ukuraho inzitizi z'imbere, wongera ubushobozi bwo kwinjira kw'amazi mu bipimo by'imiyoboro ifunze mu gihe hirindwa kuziba kw'amazi.

（4） Uburyo bubiri bwo gutera umuti kugira ngo wongere imikorere myiza

Ishyigikira imiterere ya spray ifite imiterere y’inguni zikomeye n’iy’inguni zidafite aho zibohera, itanga inguni nini zo gutwikira no gukumira kuziba kugira ngo ikore neza cyane.

Ibyiza by'ingenzi ugereranyije n'ibindi bikoresho:

（1） Ubudahangarwa bw'imyenda idahuye

Ubukomere: Udupira twa SiC tugira ubukomere bwa Mohs bwa 9.5 (ugereranyije na 8.0 ku bumba rya alumina, 6.0 ku cyuma gifite chromium nyinshi), bigatuma dushobora kwihanganira kwangirika gukabije mu mabuye y'agaciro, ivu ry'amakara n'ifu y'icyuma.

Igihe cyo kurama: Igihe cyo kubikora kirenga 5–10× ibikoresho gakondo (urugero: imigozi ya rubber cyangwa polyurethane) mu bikorwa bikomeye nk'imashini zitunganya imipira cyangwa ipompo z'amazi.

（2）Kuturika no Kutagira ibinyabutabire mu mubiri

Ubudahangarwa bwa aside/alkali: Irwanya aside sulfuriki nyinshi (98%), hydroxide ya sodiyumu (50%), n'umunyu washongeshejwe (urugero: NaCl-KCl kuri 800°C), mu gihe ibyuma bishira vuba kandi polymer zigashira.

Kudahumanya: Ubuso budakora neza butuma habaho ubuziranenge mu gukora bateri za semiconductor cyangwa lithium, bitandukanye n'ibyuma bishobora kwanduzwa na ion leaching.

(3) Guhagarara neza mu bushyuhe bukabije

Ubudahangarwa bw'ubushyuhe: Ikora buri gihe kuri 1,600°C (ugereranije n'urugero ntarengwa rwa alumina rwa 1,200°C) hamwe n'ubushyuhe buke (CTE: 4.0×10⁻⁶/℃), ikarinda gucika kw'amatanura cyangwa amatanura ashongeshwa.

Ubudahangarwa bw'ihindagurika ry'ubushyuhe: Igumana ubuziranenge bw'imiterere yayo mu gihe ubushyuhe buhindagurika cyane (urugero: kuzimya kuva kuri 1,000°C kugeza ku bushyuhe bw'icyumba), bitandukanye n'ibibumbano byoroshye.

(4) Ingufu zikoreshwa neza kandi zikozwe mu buryo bworoheje

Ubuso bwa SiC busesuye (Ra <0.1 μm) bugabanya ubudahangarwa bw'amazi ku kigero cya 30–50% ugereranije n'ibyuma bikozwe mu cyuma, bigabanura ikiguzi cy'ingufu zo gupompa.

Kuzigama ibiro: Ubucucike bwa 3.1 g/cm³ (ugereranyije na 7.8 g/cm³ y'icyuma) byoroshya ishyirwaho no gushyigikira ibikoresho byoroheje mu byuma bitunganya indege cyangwa mu byuma bigendanwa.

Shandong Zhongpeng Special Ceramics Co., Ltd ni imwe mu mashami manini ya silicon carbide ceramic mu Bushinwa. SiC technical ceramic: Ubukana bwa Moh ni 9 (Ubukana bwa Moh bushya ni 13), bufite ubudahangarwa bwiza bwo kwangirika no kwangirika, ubukana bwiza bwo kwangirika no kurwanya oxidation. Igihe cy'akazi k'ibicuruzwa bya SiC ni inshuro 4 kugeza kuri 5 ugereranyije n'ibikoresho bya alumina 92%. MOR ya RBSiC ikubye inshuro 5 kugeza kuri 7 ugereranyije na SNBSC, ishobora gukoreshwa mu miterere igoye cyane. Uburyo bwo gutanga ibiciro ni bwihuse, gutanga ibintu ni uko byasezeranijwe kandi ubwiza ni ubwa mbere. Buri gihe dukomeza guhangana n'intego zacu kandi tugasubiza imitima yacu kuri sosiyete.
