kuvala chitoliro cha ceramic chosagwira
Silicon carbide ceramic: Kulimba kwa Moh ndi 9.0 ~ 9.2, kukana kwambiri kukokoloka ndi dzimbiri, kukana kwambiri 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, ingagwiritsidwe ntchito pazithunzi zovuta kwambiri.
Silicon carbide wear resistance, imapangidwa kuchokera ku silicon carbide ndi carbon pa kutentha kwakukulu, ndi yamtundu wa silicon carbide product.The silicon carbide wear resistance parts imagwiritsidwa ntchito kwambiri pamigodi, kuphwanya zitsulo, kuyang'anira ndi kunyamula zovala zapamwamba, zowonongeka kwambiri. zamadzimadzi, zomwenso ndi zoyenera kwambiri pamakina opangira zinthu zolondola kwambiri komanso zosindikiza, monga pampu yothamanga, pampu yamagetsi etc. kuvala kukana, kukana zimakhudza, kutentha kukana, asidi ndi kukana kwa dzimbiri zamchere ndi zina zotero, ndipo moyo weniweni wautumiki ndi nthawi yoposa 6 ya polyurethane. Ndizoyenera kwambiri pa ntchito ya gulu, ndende ndi kutaya madzi m'thupi la abrasive amphamvu ndi zipangizo coarse-grained, wakhala bwino ntchito mu mines.Our kampani ndi katswiri pakachitsulo carbide kuvala kukana ceramic mankhwala katundu, kuuma wachiwiri kwa diamondi, ndi mkulu kuvala kukana, ntchito moyo wautali features.The kuvala kukana chitoliro ndi chigongono kuti amapangidwa yokhala ndi silicon carbide kuvala kukana, makulidwe ake a ceramic ndi 6-35mm, kapangidwe kake ndikuyika chubu cha ceramic kale chopangidwa kale mu chubu chachitsulo chofananira, ndi guluu pakati. mapaipi amiyala omwe adatengera kale, mapaipi achitsulo osamva aloyi ndi mapaipi a ceramic composite.
Reaction Bonded Silicone Carbide (RBSC) imakhala ndi mawonekedwe owoneka bwino osamva bwino, zinthu zabwino pakutentha kokwera, kukokoloka kwabwino komanso kukana kwa abrasive, zinthuzi zitha kugwiritsidwa ntchito m'njira zosiyanasiyana monga mapaipi, chigongono cha ceramic, ma nozzles opopera, ma nozzles owombera ndi zigawo 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 katundu pamwamba, 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)
- Kukana kwa okosijeni (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, mayendedwe, mapampu vane
- 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, ingagwiritsidwe ntchito pazithunzi 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.
