Silicon carbide ceramic yokhala ndi chitoliro chosamva kuvala ndi hydrocyclone m'mafakitale amagetsi

Silicon Carbide Ceramic Piping Systems: Kukonzanso Zomangamanga Zopangira Mphamvu

Mafakitale opangira magetsi amakumana ndi zovuta zogwira ntchito kwambiri, pomwe mapaipi amatha kukhala:

- Kuthamanga kosalekeza kotentha (100–650°C)

- Kuthamanga kwa tinthu ting'onoting'ono topitilira 30 m / s

- Kusintha kwa pH kuchokera ku 2-12 muzopaka gasi

- Kusinthasintha kwa cyclic pressure (0–6 MPa)

Mapaipi akale achitsulo ndi ma polima nthawi zambiri amalephera pansi pamikhalidwe iyi, kupangitsa mapaipi a silicon carbide (SiC) ceramic kusamva kuvala kukhala njira yopangira makina amagetsi amakono.

Kupambana kwa Sayansi Yazinthu

Mapaipi a ceramic a SiC amaphatikiza zinthu zapadera zofunika pakugwiritsa ntchito mphamvu zamagetsi:

- Vickers Kuuma 28 GPa (4 × kulimba kuposa tungsten carbide)

- Mtengo Wovala <0.1 mm³/N·m (ASTM G65)

- Thermal Conductivity 120 W/m·K (yapamwamba kuposa chitsulo chosapanga dzimbiri)

- Chemical Inertness (imakana 98% H₂SO₄ pa 300 ° C)

Ubwino Wogwira Ntchito mu Critical Systems

1. Kusamalira Malasha & Mayendedwe a Phulusa

- Kupirira 5-7 mm/chaka kuvala kosokonekera kuchokera ku 60% slurry zolimba

- Pitirizani kuchepetsa kuchepa kwa <5% pa maola 10,000 ogwirira ntchito

2. Flue Gas Desulfurization (FGD)

- Kuchita kosagwira pH mumayendedwe a miyala yamchere ya miyala ya miyala

- Kuchotsa dzimbiri chifukwa cha kloridi

3. Kuwulutsa Phulusa

- 0.08 μm kuuma pamwamba kumachepetsa kumamatira kwa tinthu

- Gwirani mphamvu ya 50 tph pamakona a 35 °

Kusintha kwachuma

Oyendetsa minda amafotokoza phindu loyezeka:

- Kuchepetsa 70% m'malo osakonzekera mapaipi

- 55% yotsika mtengo yokonza ntchito

- 18% yasintha magwiridwe antchito amafuta mumayendedwe a nthunzi

- 40% moyo wautali wadongosolo motsutsana ndi njira zina za alloy

Kuyika & Kusinthasintha kwa Ntchito

- Magawo a modular 1-6 m okhala ndi zolumikizira za flanged / ulusi

- Kuchepetsa kulemera ndi 60% poyerekeza ndi zitsulo zofanana (3.2 g/cm³ kachulukidwe)

- Itha kubwezeretsedwanso ku zothandizira mapaipi omwe alipo ndi ma hanger

- Yogwirizana ndi machitidwe owunikira anzeru pakulosera kwanthawi zonse

Zopanga Zam'tsogolo

Mayankho am'mibadwo yotsatira a SiC amaphatikiza:

- Gradient porosity pochepetsa kupsinjika kwamafuta

- Zosintha zamachitidwe zama electrostatic precipitation

- Malumikizidwe a ceramic-elastomer a Hybrid kuti achepetse kugwedezeka

- Zodziyeretsa zokha pamwamba pa nano-textures

Kuchokera ku zomera zowotchedwa ndi malasha kupita kumalo opangira mphamvu zowonongeka, mapaipi a silicon carbide ceramic amafotokozeranso kudalirika kwa zomangamanga zamagetsi. Kuphatikizika kwawo kwapadera kwa mphamvu zamakina, kupirira kwa kutentha, ndi kukhazikika kwa mankhwala kumatsimikizira kugwira ntchito mosalekeza pansi pa zovuta kwambiri - kusintha ndandanda yokonzekera kuchoka ku kukonzanso kosasunthika kupita kumalo okonzekera, okwera mtengo.

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, itha kugwiritsidwa ntchito pazinthu 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.
