Cov khoom qhia khoom ntawm xim av fused alumina rau cov khoom siv abrasives
1. Cov Khoom Txheej Txheem
Xim av fused alumina (BFA) rau cov abrasives yog qhov siab heev ntawm lub tshuab hluav taws xob hauv lub tshuab hluav taws xob siab tshaj 2000 degree, ua raws li los ntawm kev txias thiab crystallization. Nrog rau cov ntsiab lus al₂o₃ ntau dua los yog sib npaug rau 94.5%, nws ua kom pom kev zoo nkauj, siab- cov khoom siv ntse. Dav siv nyob rau hauv cov av uas tau sib tsoo (cov log abasive), blasting abrasives (bulles abrasive (thiab cov khoom siv Abras
2. Cov yam ntxwv tseem ceeb thiab cov txiaj ntsig
Hardness Hardness & Hnav Kuj
Mohs hardness ntawm 9, thib ob tsuas yog pob zeb diamond thiab silicon carbide, ua rau nws ua cov khoom siv nyuaj (piv txwv li, alloys, hlau stainless).
Cov nplej nplej ntse ua kom muaj kev sib tsoo siab thiab txuas ntxiv lub neej.
Tshaj teb cov tawv
Piv rau cov neeg dawb fused alumina thiab silicon carbide, bfa muaj ntau dua fracture, ua rau nws zoo tagnrho rau kev tu kom huv si, steel phaj descaling).
Zoo kiag -} Lub peev xwm heev
Abrasive lis nyom tsis tu ncua kev ua kom sib haum thaum siv, ua rau cov npoo txiav tshiab txhawm rau tswj cov kev sib tsoo thiab txo cov dulling.
Zoo tshuaj ruaj khov
Tiv taus kub thiab oxidation, haum rau ob qho chaw qhuav thiab ntub kev sib tsoo ib puag ncig yam tsis muaj cua txias.

Grain loj ntau (FEPA / ANSI Txuj):
Coarse nplej: F8-F36 (rau kev sib tsoo hnyav thiab txiav)
Nruab Nrab Nplej: F40-F120 (RAU PROCKISION sib tsoo thiab polishing)
Zoo nplej: F150 - F800 (rau Ultra-Precision Machining)
4. Cov Txheej Txheem Ntau Lawm
Cov Khoom Siv Raw Xaiv: High {-}} alumina bauxite (al₂o₃ ntau dua los yog sib npaug ntawm 85%) tov nrog coke thiab hlau filings kom txo impurities.
Hluav taws xob arc rauv rauv: Molten at 2200 qib kom cais impurities li sio₂ thiab fe₂o₃.
Crushing & shaping: Cov menyuam milling thiab pob milling ua kom zoo qhov ntsuas (piv txwv, txhim kho cov khoom muaj zog isometric).
Acid Ntxuav & Sib Cab Sib Nqus: Tshem tawm cov hlau dawb thiab impurities los txhim kho kev coj dawb huv.
5. Cov ntawv thov tseem ceeb
Ua kom cov abrasives
Cov Log Sib Tsoo: Rau kev sib tsoo zoo ntawm cov hlau thiab tsheb kho tsheb.
Hliav pob zeb / Cov pob zeb roj: Rau cov cuab yeej precision thiab pwm hnav khaub ncaws.
Coated abrasives
A. Abrasive txoj sia / Sandpaper: Rau cov khoom sib luag ntawm cov ntoo thiab cov hlau.
Nrov nrov plig plawg discs / sib tsoo Discs: Rau weld tu thiab stainless hlau polishing.
Blasting & Kev Kho Cov Nto
Hlau Descaling (SAE Txheem G40-G80 GRIT).
Iav etching thiab pob zeb engraving (kev cai grit muaj).
Lwm Cov Ntawv Thov
Kev txhawb nqa cov muab tub lim rau cov khoom siv rau kev cob qhia rau- bured abrasives.
Aggregate rau hnav -} tiv taus flooring.
6. Cov neeg siv khoom tus nqi
Nqi -}}}}: 15% {- 20% tus nqi qis dua li dawb fused alumina, zoo tagnrho rau kev siv cov nplai loj.
Tau sib kho: Yam sib tw, qhov ntau thiab tsawg, thiab kev sib txuas sib xyaw ua ke muaj kom tau raws li cov kev xav tau tshwj xeeb.
7. Ntim & Cia
25kg / hnab (woven hnab) lossis 1 - tuj pallets (noo xab-pov thawj qhwv).
Khaws rau hauv ib puag ncig qhuav los tiv thaiv clumping.
Brown fused alumina rau abrasives, nrog nws qhov nyuaj heev, kev siv tawv me, thiab tus nqi xaiv nyob hauv ntiaj teb kev sib tsoo cov ntawv thov. Kev them nyiaj yug yog muaj -} Hu rau peb rau kev sab laj!
(Nco tseg: tsis muaj cov ntsiab lus thiab cov ntsiab lus tuaj yeem hloov kho raws cov ntaub ntawv khoom tiag.)
