Hnav resistant ceramichauv ob sab phlu muab kev cuam tshuam zoo heev thiab tiv thaiv kev puas tsuaj. Tsim tshwj xeeb rau kev siv txhua qhov chaw hnav thiab puas yog ib qho teeb meem, ZPC® linings txo qis sijhawm thiab kev saib xyuas. SiC ceramic linings yog heev resistant rau abrasive los ntawm tej yam ntaub ntawv xws li silica, ore, iav, slag, ya tshauv, limestone, thee, coke, pub, grain, chiv, ntsev thiab lwm yam khoom abrasive heev.
Abrasion resistant thiab hnav resistant linings los ntawm Zhongpeng haum ntau industries. Cov neeg siv khoom sib txawv los ntawm kev lag luam hmoov mus rau thee, fais fab, mine thiab zaub mov kev lag luam uas FGD nozzles tau pom zoo siv rau hauv Tuam Tshoj Electric Power Group. ZPC hnav tsis kam linings tau muag thoob plaws hauv Tebchaws Meskas, Canada, Austrilia, Mexico, South Africa, thiab lwm yam. SiC linings, daim hlau thiab blocks yog siv nyob rau hauv daim ntawv thov xws li kav, tees, luj tshib, separators, cyclones, silos, bunkers, qhob thiab steel troughs, chutes, impellers thiab agitators, kiv cua thiab kiv cua casings, conveyor screws, saw conveyors, mixers, pulpers; qhov twg qhov kev sib txhuam-induced abrasion yog ib qho teeb meem.
Abrasion resistant vuas rau hnav tiv thaiv, kom tau raws li cov neeg siv khoom tshwj xeeb abrasion, cuam tshuam thiab teeb meem corrosion. Kev siv ZPC SiC hnav cov hlua tiv thaiv ntawm cov khoom muaj teeb meem ntxiv rau kev txuag nyiaj tseem ceeb vim lawv lub neej ua haujlwm ntev. Tus nqi ntawm cov khoom hloov pauv, lub sijhawm poob qis ntawm kev ua haujlwm, kev tu cov nroj tsuag thiab tus nqi ntawm kev saib xyuas kev ua haujlwm yog tag nrho txo qis. Cov nyiaj khaws cia tau tshwm sim yuav them rau cov hlua khi thiab kev teeb tsa hauv lub sijhawm luv luv.
Silicon carbide sic bushing yog ib hom tshiab ntawm high-tech thiab hnav-resistant khoom nyob rau hauv lub ntiaj teb no. Nws yog tsim los ntawm high-purity silicon carbide hmoov, high-purity high-temperature carbon dub thiab binders, los ntawm pouring, blanking, sintering, thiab xuab zeb-tshem cov txheej txheem, ua los ntawm ib tug composite siab hnav cov khoom.
Nws yog tam sim no siv los ua bushing hauv cov khoom siv mining, xws li tooj liab, kub, hlau ore, npib tsib xee ore thiab lwm yam hauv cov hlau uas tsis yog hlau. steel bushings thiab alumina bushing.
1.Kev thov ntawm sic bushing hauv kev lag luam mining
Rau mine filling, cov concentrate hmoov thiab tailings kev thauj mus los tau hnyav hnyav ntawm cov raj xa dej.Cov kev pab cuam lub neej ntawm cov ore hmoov conveying pipeline siv yav dhau los yog tsawg tshaj li ib xyoos, thiab tam sim no xaiv silicon carbide bushings tuaj yeem ua rau kev pab cuam lub neej ntau dua. 10x ua.
2.Vim li cas silicon carbide linings tau dav siv hauv kev lag luam mining?
Vim hnav tsis kam ntawmcev ceramics, hauv qab no yog kev sib piv ntawm hnav tsis kam ntawmcev ceramics thiab lwm yam ntaub ntawv.

5.Silicon carbide bushing kev twb kev txuas
(1) Thaum cov kav dej hloov tau siv los txuas cov kav dej, qhov ntev ntawm ob qhov kawg ntawm lub tes tsho hloov pauv yuav tsum tau hloov kho symmetrically. Expansion gap yuav tsum ua raws li cov xwm txheej hauv zos lossis cov kev cai tsim chav haujlwm.
(2) Thaum siv flange txuas, lub ntsej muag flange yuav tsum tau yaug nrog lub ntsej muag kawg ntawm cov yeeb nkab sib xyaw
Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd yog ib qho ntawm cov loj tshaj plaws silicon carbide ceramic cov khoom siv tshiab hauv Suav teb. SiC technical ceramic: Moh lub hardness yog 9 (New Moh's hardness yog 13), nrog zoo heev tiv taus yaig thiab corrosion, zoo heev abrasion - kuj thiab anti-oxidation. SiC khoom lub neej kev pab cuam yog 4 mus rau 5 zaug ntev dua 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 npaug ntawm SNBSC, nws tuaj yeem siv rau cov duab ntau dua. Cov txheej txheem hais tau nrawm, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob. Peb ib txwm pheej sim sim peb lub hom phiaj thiab muab peb lub siab rov qab los rau zej zog.
