Uburyo bwo gukora ikibaho cya fibramic

IRIBURIRO: Gusaba kuzamuka kwa ceramic fibre​

Imbaho ​​za fibreni ngombwa mu nganda zisaba kurwanya ubushyuhe bukabije, nka metallurgie, petrochemical, na Aeropace. Iyi myambaro, ikozwe muri fibre-fibre-fibre, itanga inzego zoroheje, imikorere myiza yubushyuhe (0.12-0.25 W / M · k), kandi ituze kuri1.600 ° C (2,912 ° F). Aka gatabo kigana mubikoresho fatizo, intambwe zisangwa, nuburyo bwiza bwo kugenzura uburyo bwo gukora fibre ya ceramic neza kandi neza.

​1. Ibikoresho fatizo kubibaho bya firamic​

Umusaruro utangirana ibikoresho byiza cyane:

• ​Alumina (Al₂o₃): 45-55% kubibaho bisanzwe; ≥60% kumanota menshi.
• ​Silica (Sio₂): 35-45%, iringaniza ituje ryumuriro na fibre.

​Ibipimo by'ingenzi​:

• ​Fibre: 2-4 μm (bigira ingaruka guhinduka no kwikinisha).
• ​Kurasa: ≤5% (uduce duto dugabanya imikorere).

​2. Intambwe ya-intambwe yo gukora​

​Intambwe ya 1: Gushonga na fibrisation​

• ​Gushonga: Ibikoresho fatizo birashonga1.600-1,800 ° C.Mu itanura rya ARC cyangwa itambutsa itanura.
• ​Fibersalisation: Ibikoresho byashongeshejwe birazunguruka muri fibre ukoresheje:
  • ​Uburyo bwo kuvuza: Inzuki zose zo mu kirere zikora fibre ngufi.
  • ​Uburyo bwo kuzunguruka: Imbaraga za Centrifugal zitanga igihe kirekire, zimurika.

​Intambwe ya 2: Gukusanya fibre no gushiraho​

• ​Icyegeranyo cy'icyumba: Fibre ituma ikingidoro kirekuye kuri convoyeur.
• ​Vacuum: Fibre ivanze na binders na vacuum.

​Intambwe ya 3: Kanda kandi byumye​

• ​Hydraulic kanda: Menyesha urupapuro rwo kwibasira ubucucike (260-320 kg / m³​).
• ​Kumanura: Kuraho ubushuhe kuri120-200 ° C.Gukomera ku kibaho.

​Intambwe ya 4: Gukata no kurangiza​

• ​CNC Gukata: Ikibaho cyaciwe neza mubunini busanzwe (urugero, 1,200 × 600 mm) cyangwa imiterere yihariye.
• ​Kwifuza hejuru: Kumenyekanisha vermiculite cyangwa aluminimu bibangamira ubw'amabuye y'agaciro.

​3. Ibikoresho bikoreshwa mu musaruro​

​4. Kugenzura ubuziranenge no kugerageza​

• ​Ubucucike: Yapimwe ukoresheje Astm C167 (intego: 260-320 kg / m³).
• ​Imbaraga zo gukumira: ≥0.5 MPA (ASTM C133).
• ​Umurongo: ≤3% Nyuma ya 24h kuri 1.350 ° C (ISO 2477).

​Inenge rusange & ibisubizo​:

• ​Guswera: Hindura ibirimo binder cyangwa umuvuduko wumye.
• ​Gutandukanya Fibre: Hindura icyuka cyo gukora igitutu.

​5. Umutekano no gutekereza ku bidukikije​

• ​Kurinda abakozi: Koresha masike ya N95, amaherezo, na Hepa ventilation kugabanya guhumeka fibre.
• ​Gucunga imyanda: Ongera uhinduke-gukata; Kujugunya imyanda kuri OSHA 29 CFR 1910.1001.
• ​Kugenzura ibikaruka: Kuramo itanura ryumunaniza (so₂, nox).

​6. Gusaba ibibaho bya fibramic​

• ​Inganda: Ling for steel asubiramo itanura.
• ​Amashanyarazi: Insulation yo kubaka no guverineri.
• ​Aerospace: Inzitizi zubushyuhe muri moteri ya roketi.
• ​Imishinga ya Diy: Intangaruji yo murugo.

​7. Ibibazo bijyanye na CERATIC FEREIDE​

​Ikibazo: Nshobora gukora imbaho ​​ya firamic Curiro murugo?​
Igisubizo: Ntabwo hasabwa-ibikoresho byo mucyiciro hamwe na protocole yumutekano ni ngombwa.

​Ikibazo: Niki giciro cyo kubyara imbaho ​​za firamic?​
A: Konti y'ibikoresho fatizo kuri 50-60% y'ibiciro; Igihingwa gito gisaba ~ $ 500k ishoramari.

​Ikibazo: Umusaruro ufata igihe kingana iki?​
Igisubizo: Iminsi 3-7 yo gushonga kugeza kubamba barangije.

​8. UMWANZURO: Umufatanyabikorwa ufite impuguke kubisubizo byiza​

Inganda zikoreshwa fibre zisaba ubushishozi, zigezweho, kandi zigenzura neza. Kubuto, gukorana nabatanga ibicuruzwa byemewe (urugero,NutecCyangwaIsolite) Kwemeza kubahiriza no gukora neza. Kubikenewe binini, bikora inzira zikoreshwa na CNC Gukata no gucuruza robo kugirango wongere umusaruro.
