553 vs 441 Silicon Hlau Powder: Qib thiab Mesh Xaiv Qhia

Dab tsi yog 553 thiab 441 Silicon Hlau Powder?

Silicon hlau hmoov yog cais los ntawm silicon cov ntsiab lus thiab particle loj faib. Qib 553 txhais tau hais tias muaj siab - purity hmoov nrog 99.9% silicon, nyob rau hauv uas thawj ob tus lej qhia qhov siab tshaj plaws hlau thiab txhuas cov ntsiab lus (0.5% txhua) thiab tus lej thib peb cov ntsiab lus calcium ntau tshaj (0.3%). Qib 441 muaj 99.5% silicon nrog tswj hlau thiab txhuas txwv ntawm 0.4% txhua. Tus lej mesh txhais tau hais tias qhov loj me: 200 mesh sib haum rau kwv yees li 74 μm thiab 325 mesh rau kwv yees li 44 μm. Ob qib yog tsim los ntawm crushing thiab milling silicon hlau, ua raws li sieving thiab sib nqus sib cais; Cov tshuaj lom neeg muaj pes tsawg leeg feem ntau raug txheeb xyuas tawm tsam GB / T 2881 lossis sib npaug thoob ntiaj teb cov lus qhia ua ntej xa khoom.

Yuav ua li cas Particle Size cuam tshuam rau kev ua tau zoo

Cov khoom me me nthuav tawm thaj chaw loj dua, uas ua rau kom tawg thiab cov tshuaj tiv thaiv kinetics hauv cov txheej txheem molten hlau lossis tshuaj lom neeg. A 325 mesh hmoov yaj sai dua thiab faib ntau yam sib xws, tab sis nws tsim cov plua plav ntau dua thiab yuav tsum tau ntim cov khoom noj thiab tshuaj. Coarser 200 mesh cov ntaub ntawv ntws tau yooj yim dua, ua kom muaj plua plav tsawg dua, thiab yooj yim rau khaws, thauj thiab pub. Qhov kev xaiv ntawm mesh yuav tsum yog li ntawd phim cov txheej txheem tuav lub sij hawm thiab cov txheej txheem tuav twb ntsia tau rau hauv cov nroj tsuag.

Hom Daim Ntawv Thov Scenarios

Cov khoom siv hluav taws xob thiab cov khoom siv hnub ci: 553 siab- qib purity yog qhov zoo dua qhov uas cov kab hlau thiab txhuas tuaj yeem ua rau cov khoom siv hluav taws xob tsis zoo lossis kev ua haujlwm photovoltaic.

Organosilicon chemicals: 553 qib muab cov khoom siv silicon zoo ib yam rau silicone monomer synthesis.

Steelmaking thiab ferrosilicon ntau lawm: qib 441 muaj kev lag luam silicon cab kuj rau deoxidation thiab alloying.

Cov khoom siv refractory thiab vuam: ob qib tuaj yeem sib xyaw kom sib npaug ntawm cov khoom siv thiab cov nqi.

FAQ

1. Dab tsi yog qhov txawv ntawm 553 200 mesh thiab 441 325 mesh hmoov?

553 muaj 99.9% silicon ntawm ib coarser 200 mesh, thaum 441 muaj 99.5% silicon ntawm ib tug finer 325 mesh. Tus thawj suits siab -purity tshuaj thiab hluav taws xob siv; qhov thib ob haum rau cov txheej txheem metallurgical qhov twg sai dua thiab cov nqi qis dua.

2. Cov 441 hmoov puas tuaj yeem siv rau hauv cov khoom siv hluav taws xob?

Tsis pom zoo. Qhov siab dua hlau thiab txhuas cov ntsiab lus ntawm 441 qib tuaj yeem qhia cov kab mob hauv cov khoom siv hluav taws xob thiab cov hnub ci; 553 lossis siab dua purity qib yuav tsum tau teev tseg.

3. Mesh loj npaum li cas cuam tshuam cov tshuaj tiv thaiv ceev?

Finer 325 mesh hais muaj qhov tshwj xeeb ntawm thaj chaw ntau dua 200 mesh cov khoom, ua rau thaj chaw sib cuag nrog cov tshuaj tiv thaiv nruab nrab thiab ua kom nrawm nrawm thiab sib xws hauv cov hlau lossis cov tshuaj da dej.

4. Yuav tswj cov particle loj li cas?

Kev tsim khoom siv vibrating cov ntxaij vab tshaus los yog huab cua classifiers ua raws li kev soj ntsuam hauv chav kuaj sieve. Cov neeg muag khoom muaj npe nrov tshaj tawm COA uas qhia txog qhov nominal mesh, oversize feem thiab nplua cov ntsiab lus rau txhua pawg.

5. Dab tsi yog ntim rau silicon hlau hmoov?

Standard export ntim yog 1 MT jumbo hnab los yog 25 kg noo noo- ntawv pov thawj- hnab yas rau ntawm pallets, nrog xaiv lub tshuab nqus tsev ntim rau siab - purity qib. Ntim yuav tsum tau lees paub nrog tus neeg muag khoom kom phim koj cov khoom siv.

6. Cov mesh loj tuaj yeem kho tau?

Yog lawm. Mills tuaj yeem tsim kev txiav nruab nrab xws li 100, 200, 325 lossis 400 mesh, thiab kev sib xyaw ua ke tuaj yeem ua kom haum rau cov txheej txheem tshwj xeeb. Yam tsawg kawg nkaus txiav txim kom muaj nuj nqis siv rau qhov tsis yog - tus qauv txiav.
