Cov kev tshawb pom tseem ceeb
Cov naj npawb ntawm cov npe - yog cov npe luv rau qhov siab tshaj plaws impurity cov ntsiab lus:553=Fe Tsawg dua lossis sib npaug li 0.5%, Al Tsawg dua lossis sib npaug 0.5%, Ca Less dua lossis sib npaug li 0.3%; 3303=Fe Tsawg dua lossis sib npaug li 0.3%, Al Tsawg dua lossis sib npaug rau 0.3%, Ca Less dua lossis sib npaug li 0.03% (raws li GB / T 2881 tus qauv).
Markus 553Tsim nyog rau cov kev daws teeb meem zoo hauv aluminium alloy ntau lawm, steel smelting thiab foundries;3303siv nyob rau hauv tshuaj, hluav taws xob thiab photovoltaic txheej txheem uas purity yog ib qho tseem ceeb.
Ob hom no sib txawv tsis yog cov ntsiab lus ntawm silicon xwb, tab sis saum toj no tag nrho los ntawm kev tswj cov impurities: calcium thiab txhuas yog cov ntsiab lus txhais.
Cov duab luam tawm yog cov txiaj ntsig kev lag luam; Nco ntsoov xyuas cov tshuaj muaj pes tsawg leeg, particle loj thiab ntim nrog daim ntawv cog lus xa khoom thiab daim ntawv pov thawj batch.
Cov lej stamp txhais li cas?
Hlau silicon (txheej txheem silicon) yog tsim los ntawm carbothermic txo ntawm quartz nyob rau hauv ore-smelting furnaces thiab yog cais raws li lub siab tshaj plaws tso cai cov ntsiab lus ntawm peb lub ntsiab impurities - hlau (Fe), txhuas (Al) thiab calcium (Ca). Cov npe siv hauv kev lag luam thoob ntiaj teb (xws li 553, 441, 3303 thiab 2202) qhia cov kev txwv no hauv kaum thiab pua pua ntawm ib feem pua: thawj tus lej hais txog Fe, thib ob - rau Al, thiab thib peb - rau Ca.
Raws li Suav lub teb chaws tus qauv GB / T 2881 ("Metallic Silicon"), cov qhab nia raug txiav txim los ntawm cov kev txwv tsis pub dhau, thiab cov ntsiab lus silicon yog qhov seem. Tias yog vim li cas rau qib 553 Si Ntau dua lossis sib npaug rau 98.5% feem ntau yog qhia, thiab rau 3303 - Si Ntau dua lossis sib npaug rau 99.37%: ob qhov ntsuas tau los ntawm kev rho tawm cov impurity txwv qhov tseem ceeb ntawm 100%.

Cov duab qhia yog cov txiaj ntsig kev lag luam. Kev txwv rau cov hom yog txiav txim siab los ntawm tus qauv kev tswj hwm (GB / T 2881) thiab yuav tsum tau lees paub hauv daim ntawv cog lus muab khoom nrog daim ntawv pov thawj batch (lub Hoobkas daim ntawv pov thawj zoo).
Txhua lub npe siv nyob qhov twg?
Hom 553 - kev khwv nyiaj txiag
Aluminium alloys:ntxiv rau hypoeutectic Al-Si cam khwb cia alloys, qhov twg silicon txhim kho fluidity, castability thiab lub zog - 553 yog lub ntsiab raw khoom rau zus tau tej cov lwm yam aluminium alloys.
Steel deoxidation thiab hlau foundry:ib qho yooj yim silicon additive qhov nruab nrab theem ntawm impurities yog txais.
General metallurgy:cov txheej txheem uas tsis xav tau kev tswj hwm calcium nruj.
Hom 3303 - daim ntawv thov nrog kev ua kom huv huv siab
Organosilicon (silicones):Cov ntsiab lus calcium thiab aluminium tsawg pab tswj cov kev ua haujlwm catalyst hauv kev sib txuas ncaj qha (Rochow- txheej txheem Muller) ntawm methylchlorosilanes.
Semiconductors thiab hnub ci zog (SoG-Si):ib tug huv pib taw tes rau metallurgical refining, txo lub nra ntawm cov kauj ruam tom ntej refining.
Precision thiab siab zog alloys:tshwj xeeb steels thiab precision peev casting qhov twg nruj tswj ntawm impurities yuav tsum tau.
Yuav xaiv li cas ntawm 553 thiab 3303
Ua kom huv huv rau koj cov txheej txheem.Yog hais tias downstream chemistry tso cai rau Fe / Al / Ca qib ntawm 0.5 / 0.5 / 0.3, Qib 553 txo cov nqi raw khoom. Yog tias lub neej catalyst, casting zoo, lossis kev ua haujlwm muaj peev xwm nkag siab rau Ca thiab Al, 3303 yog qhov kev xaiv zoo dua.
Xav txog tus nqi tag nrho.Hom 3303 muaj tus nqi meej meej piv rau 553 hauv cov khoom lag luam raug. Overspecification yog nkim nyiaj; underestimation - rau qhov kev pheej hmoo ntawm batch rejection.
Xyuas particle loj thiab ntim.Cov khoom siv pob - rau phau ntawv thauj khoom, granules - rau pneumatic dosing systems; Pom zoo nrog tus neeg muag khoom ntawm qhov particle loj faib thiab tiv thaiv cov dej noo.
Thov kom muaj ntawv pov thawj tsom xam.Txhua qhov ntau yuav tsum tau muab nrog daim ntawv pov thawj zoo los ntawm cov chaw tsim khoom - kuaj rau tus qauv pom zoo.
Yuav kuaj dab tsi ua ntej xaj
Regulatory Framework:qhia nyob rau hauv daim ntawv cog lus tus txheej txheem tswj (piv txwv li, GB / T 2881, pom zoo tsab) thiab hom code.
Kev tshuaj xyuas:pom zoo rau cov txheej txheem kuaj thiab tshuaj ntsuam xyuas ua ntej; khaws cov qauv tswj.
Cov ntaub ntawv:batch daim ntawv pov thawj, packing daim ntawv teev, cov nqe lus ntawm kev xa khoom thiab, yog tias tsim nyog, qhov kev soj ntsuam thib peb.
Supplier qualification:ncaj qha tshawb xyuas qhov chaw tsim khoom, kev xa tawm thiab cov ntaub ntawv xa tawm - tsis txhob cia siab rau kev lag luam tsis muaj txiaj ntsig.
