Khoom siv tshwj xeeb Silicon hlau 97

Daim ntawv thov ntawmsilicon hlau 97hmoov nyob rau hauv kev lag luam photovoltaic los tsim silicon wafers, nyob rau hauv tus txheej txheem ntawm kev txiav monocrystalline los yog polycrystalline silicon wafers, yuav inevitably tsim ultra-nplua plua plav, lub fineness ntawm hmoov av yog: 5.5-12μm, vim hais tias cov hmoov av ntawm 97 hlau silicon hmoov raw cov ntaub ntawv yog sau los ntawm cov sedimentation tank, thiab tau agglomerate, tom qab yooj yim pom thiab qhuav kev kho mob, cov dej noo yog 25-48%, cov ntsiab lus silicon (tau txais puag) yog 50-73%, thiab cov khib nyiab tsim nyob rau hauv cov txheej txheem silicon wafer yog hu ua silica fume. Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm silica sludge tom qab dej poob yog 0.4-0.6/cm3.

1.Tam sim no, daim ntawv thov hom by-product silica sludge nyob rau hauv kev lag luam photovoltaic ntawm lub lag luam yog: melting thiab recrystallization rau hauv silicon ingot nrog nruab nrab zaus rauv, thiab cov txheej txheem no muaj cov txheej txheem siab rau silica sludge raw cov ntaub ntawv, thiab cov ntsiab lus silicon elemental. ntawm silica sludge tom qabsilicon hlau 97hmoov ziab yog 95-98%, uas ua rau muaj kev xaiv tsawg ntawm silica smear, thiab kev ua thiab tsim cov khoom siv silicon yuav tsim cov hmoov av ntau hauv cov txheej txheem ziab los yog hauv cov txheej txheem melting rauv smelting, ua rau cov plua plav loj. cov pa phem rau ib puag ncig, thiab tib lub sijhawm, cov txheej txheem ntau lawm belongs rau lub zog siv hluav taws xob thiab kev lag luam muaj kuab paug siab. Nws cuam tshuam nrog tsoomfwv tam sim no cov lus tawm tswv yim ntawm kev txhim kho kev lag luam, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.

2.Txoj kev tsim khoom ntawmsilicon hlau 97hmoov yog los npaj zoo tib yam silicon hlau hmoov los ntawm pre-dehydration los yog ziab, ces crushing thiab ziab. Ntawm lawv, cov silicon slurry nyoos yog cov hmoov av ultrafine tsim los ntawm kev txiav monocrystalline lossis multicrystalline silicon wafers thaum lub sij hawm tsim cov silicon wafers, thiab tau los ntawm kev ntxuav thiab nag lossis daus. Ntawm lawv, particle fineness ntawm 97 hlau silicon hmoov nyiaj rau ntau tshaj 80% nyob rau hauv ntau ntawm 38-74μm; Dej<1%; The mass percentage of impurities such as SiO2 is 2-23%; The mass percentage of elemental silicon is 75-98%. The water content of the raw silica sludge is 25-48%. During the pre-dewatering or drying process, the water content of silica sludge is controlled at 20-35%.
