I-SiC bushing, amapuleti, ama-liner namasongo
Sicela ubone ividiyo yomkhiqizo kuwebhusayithi:
Gqoka i-ceramic engazweliama-linings anikeza umthelela omuhle kakhulu nokuvikela ukumelana nokuhuzuka. Ngokukhethekile yakhelwe ukusetshenziswa noma yikuphi lapho ukuguga nokuhuzuka kuyinkinga, ama-Linings e-ZPC® anciphisa isikhathi nokunakekelwa. I-SiC linings ye-ceramic imelana kakhulu nemiphumela yokugwaza yezinto eziningi ezifana ne-silica, i-ore, ingilazi, i-slag, umlotha wempukane, i-limestone, amalahle, i-coke, okuphakelayo, okusanhlamvu, umanyolo, usawoti kanye nezinye izinto eziqhuma kakhulu.
Amalayini amelana nama-abrasion futhi angagqokeki avela eZhongpeng afanela izimboni eziningi. Amakhasimende asukela embonini yempushana kuya ezimbonini zamalahle, amandla, imayini kanye nokudla lapho amabhomu e-FGD agunyazwe ukuthi asetshenziswe e-China Electric Power Group. Izintambo ze-ZPC ezingagqoki zithengiswa kulo lonke elase-United States, eCanada, e-Australia, eMexico, eNingizimu Afrika, njll. I-Linings ye-SiC, amapuleti kanye namabhulokhi ayasebenza ezinhlelweni ezinjengamapayipi, amathayi, izindololwane, izihlukanisi, izishingishane, izisele, izikebhe, izitsha zikakhonkolo nezensimbi, ama-chute, ama-impeller nama-agitator, ama-fan blades nama-fan casings, izikulufu zokuthutha, amaketanga okuhambisa, ama-mixers, ama-pulpers; noma yikuphi lapho ukuhuzuka okubangelwa ukungqubuzana kuyinkinga.
Amathayela amelana nokuhuzuka okuvikela ukuguga, ukuhlangabezana nemihuzuko ethile yekhasimende, umthelela kanye nezinkinga zokugqwala. Ukusetshenziswa kweZPC SiC ukugqokwa kwama-linings amelana nezingxenye eziyinkinga kwengeza ekongeni okukhulu ngenxa yempilo yabo ende yokusebenza. Izindleko zokushintshwa kwezingxenye, isikhathi sokungasebenzi, ukuhlanzwa kwezitshalo kanye nezindleko zomsebenzi wokunakekelwa kwehliswe ngendlela emangalisayo. Ukonga okwenziwe kuzokhokhela ama-linings nokufakwa ngesikhathi esifushane.
I-Silicon carbide sic bushing wuhlobo olusha lwezinto ezisezingeni eliphezulu nezingagugi emhlabeni. Yakhiwe nge-high-purity silicon carbide powder, i-high-purity high-temperature carbon black kanye nama-binders, ngokuthulula, ukuvala, izinqubo zokucwilisa, kanye nokukhipha isihlabathi, ezenziwe ngomkhiqizo oyinhlanganisela wokugqoka okuphezulu.
Njengamanje isetshenziswa njengendawo yokusebenzela emishinini yezimayini, njengethusi, igolide, insimbi yensimbi, i-nickel ore nezinye ezinsimbi ezingenayo insimbi. Idlala indima yokumelana nokugqokwa okuphezulu, impilo yokugqokwa iphindwe izikhathi ezingaphezu kweziyi-10 kuneyejwayelekile. izinsimbi zensimbi kanye ne-alumina bushing.
1.Ukusetshenziswa kwe-sic bushing embonini yezimayini
Ukuze kugcwaliswe imayini, i-concentrate powder kanye ne-tailings transportation iyaguga kakhulu epayipini.Impilo yesevisi yepayipi le-ore elidlulisa i-ore elalisetshenziswa esikhathini esidlule ingaphansi konyaka owodwa, futhi manje ukukhetha i-silicon carbide bushings kungakhuphula impilo yesevisi ngokungaphezu izikhathi ezingu-10.
2.Kungani i-silicon carbide linings isetshenziswa kabanzi embonini yezimayini?
Ngenxa yokumelana nokugqoka kwei-ceramic tubes, okulandelayo ukuqhathanisa ukugqokwa ukumelanai-ceramic tubes nezinye izinto.
Ukuqhathaniswa kokumelana nokugqoka kwe-silicon carbide bushings
| Ukuhlolwa kokungafani kwe-Sandblasting (isihlabathi se-SiC) | 30% ukuhlolwa kokungafani kodaka lwe-SiO2 | ||
| Okubalulekile | Ivolumu eyehlisiwe | Okubalulekile | Ivolumu eyehlisiwe |

| Ipayipi le-Ceramic composite | 0.117 | 0.195 | 7.935×104 | 1.343×103 | 0.0193 |
5.Silicon carbide bushing uxhumano
(1) Uma amapayipi aguquguqukayo esetshenziselwa ukuxhuma amapayipi okufaka, ubude bokufakwa kweziphetho ezimbili zomkhono wepayipi oguquguqukayo kufanele bulungiswe ngokulinganayo. Igebe lokunwetshwa kufanele lisekelwe ezimweni zendawo noma izidingo zomnyango wokuklama.
(2) Uma usebenzisa uxhumano lwe-flange, ubuso be-flange kufanele busheleleke nobuso bokugcina bepayipi eliyinhlanganisela.
I-Shandong Zhongpeng Special Ceramics Co., Ltd ingesinye sezixazululo ezintsha ze-silicon carbide zobumba eChina. I-ceramic yobuchwepheshe ye-SiC: Ubulukhuni be-Moh buyi-9 (ukuqina kwe-Moh entsha yi-13), enokumelana okuhle nokuguguleka nokugqwala, ukuhuzuka okuhle kakhulu – ukumelana ne-oxidation. Impilo yesevisi yomkhiqizo we-SiC iyinde izikhathi ezi-4 kuya kwezi-5 kune-alumina material engu-92%. I-MOR ye-RBSiC izikhathi ezi-5 kuye kweziyi-7 kune-SNBSC, ingasetshenziselwa izimo eziyinkimbinkimbi. Inqubo yekhotheshini iyashesha, ukulethwa kunjengoba kuthenjisiwe futhi ikhwalithi ingeyesibili. Sihlala siphikelela ekuphonseni inselelo imigomo yethu futhi sibuyisele izinhliziyo zethu emphakathini.
