Silicon carbide yumbu mai liyi mai jure lalacewa
Silicon carbide bututu masu jurewa bututun bututu ne da aka yi su da siliki carbide kuma suna da fa'idodi masu fa'ida a fagage da yawa. Babban gasa shi ne kamar haka:
(1) Juyin Rayuwa
Lokacin jigilar kafofin watsa labarai masu lalata kamar slurry da ash kwal, tsawon rayuwar shine sau 10 na karafa, yana rage sauyawa akai-akai da asarar lokaci.
(2) Matsanancin yanayin aiki na duniya ne
Barga aiki daga -50 ℃ zuwa 1600 ℃, tare da thermal girgiza juriya don hana fatattaka, dace da high-zazzabi al'amuran kamar karfe da kuma sinadaran masana'antu.
(3) Yawan amfani da abu ɗaya
A lokaci guda warware manyan matsalolin guda huɗu na lalacewa, lalata, yawan zafin jiki, da rigakafin fashewa.
(4) Mai nauyi da makamashi
Zane mai nauyi yana rage farashin sufuri da shigarwa, kuma ƙarancin juzu'i yana rage yawan amfani da makamashi.
The murkushe fa'idar silicon carbide bututu idan aka kwatanta da na gargajiya kayan:
| Girman aiki | Silicon carbide bututun | Bututun ƙarfe / Filastik |
| Saka juriya | Hardness 2800HV (sau 5 na karfe), tsawon rayuwa sau 10 fiye da na bututun da ba na ƙarfe ba. | Karfe yana da saurin lalacewa da tsagewa, yayin da filastik yana da ƙarancin ƙarfi (PE <1 HV) |
| Babban zafin jiki juriya | Mai jurewa ga yanayin zafi na 1600 ℃ da girgiza thermal (ƙimar haɓakar thermal 4 × 10 ⁻⁶ / ℃) | Bakin karfe yana da haɗari ga oxidation a yanayin zafi mai yawa, yayin da robobi ke da juriya na zafin jiki na ƙasa da 80 ℃ |
| Juriya na lalata | Mai jurewa ga acid mai ƙarfi (ƙarfin sulfuric acid), tushe mai ƙarfi, da narkakken ƙarfe. | Bakin karfe yana samun gogewar lalata lokacin da aka fallasa shi zuwa ions chloride, yayin da filastik yana da iyakancewar juriyar sinadarai |
| Mai nauyi | Girman 3.0 ~ 3.14 g/cm ³ (60% ya fi karfe) | Bututun ƙarfe suna da girma kuma suna da tsadar shigarwa |
| Fadada Aiki | Anti static (rauni mai rauni), tsaftar darajar semiconductor | Karfe suna buƙatar ƙarin magani don rigakafin fashewa, yayin da robobi ke da saurin kamuwa da cuta |
A takaice dai, kusan babu wani madadin maganin bututun silikon carbide lokacin da ake jigilar kafofin watsa labarai masu lalata da kuma juriya kamar su acidic slurries da ash gas mai zafi mai zafi.
Idan kuna da tambayoyi, da fatan za ku iya tuntuɓar mu a kowane lokaci.
Shandong Zhongpeng Special Ceramics Co., Ltd yana daya daga cikin manyan sabbin kayan yumbu na silicon carbide a cikin kasar Sin. SiC fasaha yumbura: Moh's taurin ne 9 (New Moh ta taurin ne 13), tare da m juriya ga yashewa da lalata, m abrasion - juriya da anti-oxidation. Rayuwar sabis na samfurin SiC shine sau 4 zuwa 5 fiye da 92% kayan alumina. MOR na RBSiC shine sau 5 zuwa 7 na SNBSC, ana iya amfani dashi don ƙarin sifofi masu rikitarwa. Tsarin zance yana da sauri, isarwa kamar yadda aka yi alkawari kuma ingancin ba shi da na biyu. Kullum muna dagewa wajen kalubalantar manufofinmu da mayar da zukatanmu ga al'umma.
