Umuyoboro wa ceramic ni iki? Igitabo cyuzuye cyo kwishyurwa cyane

Umuyoboro wa fibre ceramic, uzwi kandi nka ceramic fibre tube cyangwa umuyoboro wo kunozwa, ni ikintu cyihariye cyo kwishyurwa cyane cyane ibikoresho byateganijwe kugirango uhangane nubusugire bukabije. Yashyizweho cyane cyane Alumina-Filicare Fibre . Reka dusuzume ibigizemo uruhare, imitungo, porogaramu, nibyiza.

Umuyoboro wa fibre wakozwe iki?

Imiyoboro ya FibramicByakozwe hakoreshejwe fibre ya ceramic, ziva muri molten silica, alumina, nibindi bimasa. Iyi fibre ihujwe hamwe kugirango ikore imiterere yoroshye cyangwa itesha agaciro, bitewe nuburyo bwo gukora. Ibiranga ibyingenzi birimo:

• Ibirimo byinshi bya alumina: Mubisanzwe birimo 35-45% al₂o₃, kuzamura umutekano.
• Ubushyuhe buke: Kuva kuri 0.09 kugeza 0.20 W / M · k, kugabanya igihombo cyubushyuhe.
• Kurwanya ubushyuhe: Amanota yo gukomeza gukoresha kugeza 1260 ° C (2300 ° F), hamwe n'impinga yigihe gito ya 1600 ° C.
• Indorerezi: Kurwanya ruswa kuva acide, alkalis, hamwe na kama.

INGINGO Z'INGENZI N'INGENZI

1. Ubushyuhe budasanzwe

Imiyoboro ya fibre ya ceramic igabanya ibiyobyabwenge igabanya ubushyuhe, bikaba byiza kuri:

• Itanura
• Sisitemu ya ExHous
• Guhanahana ubushyuhe

2. Ikirahure no guhinduka

Gupima kugeza 80% munsi yamatafari gakondo, boroshya kwishyiriraho ahantu hafunganye cyangwa geometries igoye.

3. Kurwanya Ubushyuhe

Uhanganye n'ihindagurika ryihuse nta guswera, bingenzi kubisabwa nka:

• Aerospace Interitizi zubushyuhe
• Imyanya ya Catalytic

4. Ububiko buke

Ubushyuhe bwihuse no gukonjesha inzinguzingo biteza imbere imikorere munganda nka Umusaruro w'icyuma kandi Gukora ibirahuri.

5. Kurwanya imiti

Kudasubiramo ibintu byinshi byangirika, harimo na molten byashonze, bigatuma bikwiranye na:

• Imiyoboro ya peteroli
• Ibice byo gutunganya imiti

Inganda

1. Urwego rw'ingufu

• Insular: Kugabanya ibiyobyabwenge mubimera byimbaraga.
• Sisitemu y'izuba: Irinde ibice bigize izuba ryizuba (CSP).

2. Metallurgy

• Kurebisha: Irinde igihombo cyubushyuhe mubushishozi bukomeza guta.
• Gutunganya itanura: Guhagarika ibiciro byingufu muri aluminium numuringa.

3. Automotive na Aerospace

• Sisitemu ya gaze ya roza (egr) sisitemu: Igabanya imyuka muri moteri ya mazutu.
• Roketi nozzle insulation: Bahanganye n'ubushyuhe bugenda bwiyongera.

4. Kurengera ibidukikije

• Flue Filtration: Ikora nkibice byingenzi muri fibre fibre Kugabanya ivumbi no kugabanya nox.

Ubwoko bwa cyerami ya fibre

Ibipimo byo guhitamo

Iyo uhisemo umuyoboro wa fibre ceramic, tekereza:

1. Ubushyuhe: Huza ibintu bikora kubicuruzwa ntarengwa byo gukoresha ubushyuhe.
2. Diameter nubwinshi: Amahitamo meza (urugero, 3mm-50mm urukuta rwuzuye).
3. Ubucucike: Umucyo (96-128 kg / M³) na hejuru-ubucucike (200-240 kg / m³) iratandukanye.
4. Uburyo bwo kwishyiriraho: Bihuye no gusudira, guhindagurika, cyangwa guhuza.

Kubungabunga no kurinda umutekano

• Ubuzima: Mubisanzwe imyaka 5-10 ikomeza gukoresha, bitewe nibidukikije.
• Gukemura: Wambare ibikoresho birinda kugirango wirinde guhumeka neza (byashyizwe ahagaragara nkutari karcinogenic na IARC).
• Kujugunya: Bisubirwamo hakurikijwe inzira yo hejuru yubushyuhe.

Umwanzuro

Imiyoboro ya Fibramicni ngombwa mu bushyuhe bw'inganda, butanga uburimbane bwo kuramba, gukora neza, n'umutekano. Waba ushushanya itanura, uzamura uburyo bwo kunanirwa, cyangwa guteza imbere uburyo bwo guca ikoranabuhanga, gusobanukirwa imitungo hamwe nibisabwa bya fibre fibre fibraramic byemeza neza imikorere no kuzigama amafaranga. Kubisubizo bidoda, kubaza abakora inzoga zidasanzwe mubipimo ngenderwaho hamwe nibintu byateye imbere.
