Silicon Carbide ya Vickers Kuuma kwa 2000kg/mm2, imapereka chitetezo chapamwamba pakugwiritsa ntchito abrasion
Silicon carbide ceramic: Kulimba kwa Moh ndi 9.0 ~ 9.2, Silicon Carbide ya Vickers Kuuma kwa 2100kg/mm2, imapereka chitetezo chapamwamba pamapulogalamu otsetsereka abrasion ndi kukana kwambiri kukokoloka ndi dzimbiri, kukana kwabwino kwambiri kwa abrasion ndi anti-oxidation. Ndi mphamvu 4 mpaka 5 kuposa nitride yomangika silicon carbide. Moyo wautumiki ndi nthawi 7 mpaka 10 kuposa zinthu za alumina. MOR ya RBSiC ndi 5 mpaka 7 nthawi ya SNBSC, itha kugwiritsidwa ntchito pazinthu zovuta kwambiri.
Silicon carbide kuvala kukana, ndi apanga kuchokera pakachitsulo carbide ndi mpweya pa kutentha kwambiri, ndi wa mtundu wa pakachitsulo carbide product.The silicon carbide kuvala kukana mbali chimagwiritsidwa ntchito migodi, kuphwanya zitsulo, kuwunika ndi kunyamula avale mkulu, mkulu dzimbiri zamadzimadzi, komanso oyenera kwambiri mankhwala makina ndi mwatsatanetsatane mkulu ndi kusindikiza zofunika pampu ndi kusindikiza kusindikiza maginito ndi kusindikiza maginito. Material.Reaction-boma silicon carbide kuvala kukana bushing ali ndi makhalidwe a kuuma mkulu, mkulu avale kukana, kukana zimakhudza, kutentha kukana, asidi ndi alkali dzimbiri kukana ndi zina zotero, ndipo moyo utumiki weniweni kuposa 6 nthawi polyurethane.It makamaka oyenera ntchito ya gulu, ndende ndi kuchepa madzi m'thupi amphamvu abrasive ndi coarse-grained zipangizo akatswiri ambiri pakachitsulo coarse-grained silicon bwino ntchito. carbide kuvala kukana ceramic katundu katundu, kuuma wachiwiri kwa diamondi, ndi mkulu kuvala kukana, ntchito moyo wautali mbali.The kuvala kukana chitoliro ndi chigongono kuti opangidwa ndi silicon carbide kuvala kukana akalowa, ake ceramic akalowa makulidwe ndi 6-35mm, kapangidwe ndi kukhazikitsa kale sintered ceramic chubu mu lolingana caliber zitsulo chubu, ndi guluu pakati ndi zomatira pakati ndi zomatira kuponyedwa kuyerekeza ndi kukana zaposachedwa za ceramic poyerekeza ndi zida zam'mbuyo za ceramic poyerekeza ndi zida zam'mbuyomu. mapaipi, kuvala zosagwira aloyi kuponyedwa zitsulo mapaipi ndi ceramic gulu mapaipi.
Rection Bonded Silicone Carbide (RBSC) imakhala ndi mawonekedwe abwino kwambiri osamva kutentha, katundu wabwino pa kutentha kokwera, kukokoloka kwabwino komanso kukana kwa abrasive, zinthuzi zitha kugwiritsidwa ntchito m'njira zosiyanasiyana monga ma mapaipi, chigongono cha ceramic, ma nozzles opopera, ma nozzles owombera ndi zida za hydrocyclone.
ZPC zomangira zimatalikirana ndi matailosi ndi zitsulo zachitsulo. ZPC silicon carbide ceramics ndi kukana kutenthedwa kwa kutentha komanso kusamva ma abrasion zomwe zimabweretsa nthawi yayitali yothamanga ndikuchepetsa nthawi yopuma.
The anachita bonded sililicion carbide ceramic (RBSIC) ndi abwino kuvala zosagwira zakuthupi, amene makamaka oyenera abrasive amphamvu, coarse particles, gulu, ndende, kuchepa madzi m'thupi ndi ntchito zina. Chifukwa cha pamwamba katundu, ndiRBSiC / SiSiC silicon carbide liner elbow / liner chubuimatha kuteteza bwino gawolo kuchokera ku kuvala kwakukulu ndi kutentha kuti ziwonjezeke moyo wautumiki wa zida.

Chitoliro chogwira ntchito cha silicon carbide ceramic kuvala chosagwira chitoliro
Makhalidwe abwino a silicon carbide ndi awa:
- Ochepa kachulukidwe
- Mphamvu zapamwamba
- Kutentha kwabwino kwamphamvu (Reaction bonded)
- Oxidation resistance (Reaction bonded)
- Zabwino kwambiri kutentha kugwedezeka
- High kuuma ndi kuvala kukana
- Wabwino kukana mankhwala
- Otsika matenthedwe kukula ndi mkulu matenthedwe madutsidwe
Zomwe zimagwiritsidwa ntchito ndi silicon carbide zimaphatikizapo:
Amagwiritsidwa ntchito kwambiri pakugwira ntchito ndi kuvala pa kutentha kochepa kusiyana ndi khalidwe la kutentha kwambiri. Ntchito za SiC ndi monga ma jakisoni a sandblasting, zisindikizo zamapampu amadzi am'galimoto, mayendedwe, zida zamapampu, ndi ma extrusion amafa omwe amagwiritsa ntchito kuuma kwakukulu, kukana kwa abrasion, komanso kukana kwa dzimbiri kwa carbide ya silicon.
- Zida zokhazikika komanso zosuntha za turbine
- Zisindikizo, ma bearings, mapampu vanes
- Zigawo za mpira
- Valani mbale
- Mipando yamoto
- Zosintha kutentha
- Zida zopangira zopangira ma semiconductor
Makampani opanga zitsulo ndi magetsi: Chifukwa chomwe mafakitale awiriwa amagwirizanirana makamaka chifukwa mafakitale awiriwa ali ndi
Shandong Zhongpeng Special Ceramics Co., Ltd ndi imodzi mwamayankho akulu kwambiri a silicon carbide ceramic ku China. SiC ukadaulo wa ceramic: Kulimba kwa Moh ndi 9 (Kulimba kwa Moh Chatsopano ndi 13), kukana kwambiri kukokoloka ndi dzimbiri, abrasion yabwino - kukana ndi anti-oxidation. Moyo wautumiki wa SiC ndi 4 mpaka 5 nthawi yayitali kuposa 92% alumina. MOR ya RBSiC ndi 5 mpaka 7 nthawi ya SNBSC, itha kugwiritsidwa ntchito pazinthu zovuta kwambiri. Ndondomeko yobwereketsa ndi yofulumira, yobweretsera ndi monga momwe inalonjezedwa ndipo khalidweli ndi lachiwiri kwa wina aliyense. Nthawi zonse timalimbikira kutsutsa zolinga zathu ndikubwezeranso mitima yathu kwa anthu.
