421 silicon hlau, qib "421" qhia: hlau tsawg dua lossis sib npaug li 0.4%, aluminium Tsawg dua lossis sib npaug 0.2%, calcium tsawg dua lossis sib npaug 0.1%. Piv rauSilicon hlau 441(aluminium Tsawg dua lossis sib npaug li 0.4%), silicon 421 muaj ib nrab ntawm cov ntsiab lus txhuas. Dab tsi yog cov txiaj ntsig ntawm qis aluminium?

Rau kev tsim khoom organosilicon:Aluminium tshuaj lom cov catalyst; qhov qis ntawm cov ntsiab lus aluminium, qhov siab dua cov tshuaj tiv thaiv.

Rau aluminium alloy ntau lawm:Aluminium yog lub ntsiab tivthaiv, tab sis cov txhuas hauv silicon cuam tshuam rau kev tswj ntawm alloy muaj pes tsawg leeg; qhov qis dua cov ntsiab lus ntawm aluminium, qhov ntau qhov kev tswj.

Rau tshwj xeeb steel ntau lawm:Cov ntaub ntawv alumina inclusions; qhov qis dua cov ntsiab lus ntawm aluminium, cov hlau huv huv.

Yog li ntawd, yog tias koj muaj cov cai hais txog cov ntsiab lus ntawm txhuas, Si421 yog qhov kev xaiv tsim nyog dua li Silicon441.

Loj 10-100mm lumps yog siv ncaj qha raws li feedstock nyob rau hauv steel mills thiab aluminium alloy nroj tsuag. Qhov zoo ntawm cov pob loj:

Yooj yim rau pub:Lawv muab pov rau hauv lub qhov cub lossis lub ladle yam tsis muaj pa taws lossis pov tseg.

Ntau ruaj khov melting:Cov tshuaj tiv thaiv yog softer dua nrog cov hmoov zoo, uas ua rau hlawv tsawg dua -tawm.

Yog tias koj xav tau ntau qhov me me (piv txwv li, 1-10mm granules,40-200 mesh Silicon hlau hmoov), peb tuaj yeem ua lawv.

Nco tseg:421 yog qhov tseem ceeb ntawm "qis-aluminium upgrade" ntawm 441-nws muaj cov hlau tib yam li calcium, tab sis txawm tsawg dua txhuas. Yog tias koj nkag siab zoo rau txhuas, siv nyiaj me ntsis ntxiv ntawm 421 yog qhov tsim nyog.

Khoom siv

1. Kev lag luam Silicone (Feem ntau Aluminium- Cov neeg siv khoom rhiab heev)

Rau cov chaw tsim khoom ntawm cov roj silicone, silicone roj hmab, thiab silicone resin, txhuas tuaj yeem lom cov tooj liab catalyst hauv fluidized txaj reactors . 0.4% aluminium hauv 441 tej zaum yuav siab dhau, thaum 0.2% txhuas hauv 421 muaj kev nyab xeeb dua.

2. Aluminium Alloy Kev Lag Luam (High-Castings, Profiles)

Cov neeg tsim khoom ntawm A356 lub log thiab 6061 cov ntaub ntawv muaj cov kev xav tau siab rau kev tswj cov alloy muaj pes tsawg leeg . 421 muaj cov ntsiab lus aluminium qis dua, tso cai rau kev ua haujlwm ntau dua.

3. Kev lag luam steel tshwj xeeb (yuav tsum muaj siab purity)

Thaum smelting siab -cov hlau tshwj xeeb zoo, txhuas tuaj yeem tsim cov alumina suav nrog. 421 muaj cov ntsiab lus aluminium qis dua 441, ua rau cov hlau huv huv.

4. Polycrystalline Silicon, Electronic Qib Silicon

421 tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov polycrystalline silicon, los yog ntxiv purified mus rau qib siab dua ntawm silicon.

FAQ

Q: 421 thiab 441 nqi npaum li cas? Kuv yuav yuav qhov twg?

A: 421 yog me ntsis kim dua 441, tab sis tus nqi tseeb nyob ntawm lub khw. Yog tias koj ua hauj lwm nrog silicone thiab rhiab rau txhuas, peb pom zoo 421. Yog hais tias koj ua hauj lwm nrog zoo tib yam aluminium alloys los yog hlau, 441 yog txaus.

Q: Koj puas tuaj yeem lav tias cov ntsiab lus txhuas ntawm 421 tsawg dua lossis sib npaug li 0.2%?

A: Yog. Peb kuaj txhua batch nrog lub spectrometer ua ntej nws tawm hauv lub Hoobkas kom paub meej tias cov ntsiab lus txhuas tsawg dua lossis sib npaug li 0.2%. Daim ntawv tshaj tawm kev xeem tau suav nrog cov khoom xa tuaj.

Q: Puas yuav muaj hmoov nyob rau hauv 10-100mm loj daim?

A: Peb cov khoom loj yog tag nrho cov sieved, thiab cov hmoov hmoov yog tswj tsis pub dhau 3%. Yog tias koj xav tau cov khoom siv huv, koj tuaj yeem qhia rau peb, thiab peb yuav rov ua dua.
