SiC bushing, mbale, liners ndi mphete
Chonde onani kanema wazogulitsa patsamba:
Valani zolimba za ceramiczitsulo zimapereka chitetezo chabwino kwambiri komanso chitetezo chosagwirizana ndi abrasion. Zomangidwira kuti zigwiritsidwe ntchito kulikonse komwe kumakhala vuto, zomangira za ZPC® zimachepetsa kutsika ndi kukonza. SiC ceramic linings zimagonjetsedwa kwambiri ndi zowonongeka za zinthu zambiri monga silika, ore, galasi, slag, phulusa la ntchentche, miyala ya laimu, malasha, coke, chakudya, tirigu, feteleza, mchere ndi zina zowononga kwambiri.
Abrasion osamva komanso kuvala zomangira zolimba kuchokera ku Zhongpeng zimagwirizana ndi mafakitale ambiri. Makasitomala amachokera ku mafakitale a ufa kupita ku mafakitale a malasha, mphamvu, mgodi ndi chakudya komwe ma nozzles a FGD amavomerezedwa kuti agwiritsidwe ntchito ku China Electric Power Group. ZPC kuvala kukana linings amagulitsidwa ku United States, Canada, Austrilia, Mexico, South Africa, etc. Iwo ndi abwino kwa akalowa zigawo sachedwa abrasion kwambiri pakugwira zomera ndi processing ntchito. Zomangira za SiC, mbale ndi midadada zimagwira ntchito ngati mapaipi, mateti, zigongono, zolekanitsa, mvula yamkuntho, ma silo, ma bunkers, konkriti ndi zitsulo zachitsulo, chute, ma impellers ndi ma agitator, masamba akufanizira ndi ma fan casings, zomangira zolumikizira, zotengera unyolo, zosakaniza, pulpers; kulikonse kumene kukwapula koyambitsa mikangano kumakhala vuto.
Matailosi osamva ma abrasion kuti atetezedwe, kuti akwaniritse zovuta za kasitomala, zovuta komanso dzimbiri. Kugwiritsa ntchito ZPC SiC kuvala zomangira zosagwira pazigawo zovuta kumawonjezera ndalama zambiri chifukwa cha moyo wawo wautali. Mtengo wa zida zosinthira, nthawi yocheperako, kuyeretsa mbewu ndi mtengo wokonza zonse zatsika kwambiri. Zosungirako zomwe zasungidwa zidzalipira zomangira ndi kukhazikitsa mu nthawi yochepa.
Silicon carbide sic bushing ndi mtundu watsopano wazinthu zapamwamba komanso zosavala padziko lapansi. Linapangidwa ndi ufa wapamwamba wa silicon carbide powder, wotentha kwambiri wakuda wakuda ndi zomangira, mwa kuthira, kubisala, kupukuta, ndi kuchotsa mchenga, zopangidwa ndi mankhwala ovala kwambiri.
Pakali pano imagwiritsidwa ntchito ngati tchire pazida zamigodi, monga mkuwa, golide, chitsulo, nickel ore ndi zina zosakhala ndi chitsulo. Imagwira ntchito yokana kuvala kwambiri, kuvala kumakhala kopitilira 10 kuposa wamba. zitsulo zazitsulo ndi aluminiyamu.
1.Kugwiritsa ntchito sic bushing mu migodi
Pakudzaza mgodi, mayendedwe a ufa ndi ma tailings akuwonongeka kwambiri paipi. Moyo wautumiki wa mapaipi otengera ufa wa ore omwe amagwiritsidwa ntchito m'mbuyomu ndi osakwana chaka chimodzi, ndipo tsopano kusankha ma silicon carbide bushings amatha kuwonjezera moyo wautumiki kuposa 10 nthawi.
2.Chifukwa chiyani zomangira za silicon carbide zimagwiritsidwa ntchito kwambiri pantchito zamigodi?
Chifukwa cha kukana kuvala kwachubu cha ceramics, zotsatirazi ndi kufanizitsa kuvala kukana kwachubu cha ceramics ndi zipangizo zina.
Kuyerekeza kukana kuvala kwa silicon carbide bushings
| Kuyesa kusiyanitsa kwa mchenga (SiC mchenga) | 30% SiO2 mud slurry kusiyana mayeso | ||
| Zakuthupi | Voliyumu yochepetsedwa | Zakuthupi | Voliyumu yochepetsedwa |
| 97% aluminiyamu chubu | 0.0025 | 45 zitsulo | 25 |

4.Chinthu china cha silicon carbide bushings chomwe chimagwiritsidwa ntchito m'migodi - kutaya pang'ono kwa kuthamanga kukana
Kuyesa kukana kukana kwa ufa, slag ndi kayendedwe ka phulusa, zotsatira zake ndi izi:
| Zakuthupi | Kuvuta kwenikweni (△) | Kuvuta kwenikweni (△/D) | Kukana madzi kokwanira | ||

| Ceramic kompositi chitoliro | 0.117 | 0.195 | 7.935 × 104 | 1.343 × 103 | 0.0193 |
5.Silicon carbide bushing kugwirizana
(1) Pamene mapaipi osinthika amagwiritsidwa ntchito kulumikiza mapaipi oyikapo, kutalika kwa malekezero a mbali ziwiri za manja a chitoliro chosinthika kuyenera kusinthidwa molingana. Kusiyana kokulirapo kuyenera kutengera momwe zinthu ziliri m'deralo kapena zofunikira za dipatimenti yokonza.
(2) Mukamagwiritsa ntchito kugwirizana kwa flange, nkhope ya flange iyenera kusungunuka ndi mapeto a chitoliro chophatikizika.
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.
