Particle loj faib analsis rau hmoov txheej

Cov txiaj ntsig ntawm laser particle loj analyzer:

Qhov nruab nrab particle loj (qhov nruab nrab txoj kab uas hla), ciam teb ntawm particle loj thiab particle loj faib ntawm qhov dispersion.

1. Qhov nruab nrab loj ntawm cov qauv yog tsawg dua thiab ntau dua 50% ntawm cov khoom.
2. Tus ciam teb qhov loj me: ze rau qhov kev nkag siab zoo rau qhov siab tshaj plaws thiab qhov tsawg kawg nkaus particle loj. Txawm li cas los xij, qhov siab tshaj plaws thiab qhov tsawg kawg nkaus particle loj los piav txog qhov txwv sab saud thiab qis ntawm cov qauv particle loj unscientific, nws yog gene.rally cov ciam teb me me, xws li (D10, D90) = (8,60), nws sawv cev tsawg dua 8 microns hauv txoj kab uas hla suav nrog 10% thiab 90%, tus naj npawb ntawm cov khoom me dua 60 microns hauv txoj kab uas hla.
3. Lub dispersion ntawm particle loj tis = (D90-D10) / D50, dispersion, qhov me me particle loj tis yog ntau nqaim, loj heev thiab me me ntawm cov hais nyob rau hauv me me particle loj dua lub concentration.

Kev sib raug zoo ntawm particle loj thiab hmoov zoo:

Particle loj tis thiab cov zaj duab xis kev ntxhib los mos, smoothness, gloss, cov nyhuv ntawm particle, nyob tshwm sim, hmoov fluidization, cia stability thiab hmoov rov qab tus nqi yog ze ze.

1. Qhov tshwm sim, theem, thiab qhov particle: Hauv general, qhov me me ntawm cov hmoov particle loj, qhov zoo dua qhov smoothness nyob rau hauv cov xim curing; tib txheej txheej thickness, me me particle loj ntawm cov hmoov tsis yooj yim los tshwm particle; cov tsos ntawm txheej yog ntau du, du.
2. nyob cov teebmeem thiab hmoov nplej tawm los: Them los txhim kho cov hmoov nplej, cov hmoov txheej hmoov ntawm tus nqi yuav nce ntxiv. Lub ntsiab adsorption quab yuam ntawm electrostatic txau electrostatic hmoov, hmoov yield yog nyob ntawm tus nqi ntawm cov nqi ntawm cov hmoov nplej. Hmoov nrog lub zog thiab hmoov particle loj yog proportional rau lub square. Ua kom cov particle loj, hmoov nrog ntau dua noj, hmoov tus nqi. Cov hmoov particle loj loj dhau lawm, qhov loj me me, lub ntiajteb txawj nqus ntawm cov hmoov loj loj dua aerodynamic thiab electrostatic hmoov txheej thaum lub davhlau, tau poob vim lub ntiajteb txawj nqus tsis ncav cuag qhov chaw, tab sis ua rau cov hmoov nplej. Hmoov zoo heev them qis txheej daim ntawv thov kev ua tau zoo yuav poob, ultra-nplua hmoov (particle loj <10μm) yeej tsis nyob rau tib lub sij hawm cov hmoov zoo heev kuj ua rau cov hmoov ntau lawm nyuaj.
3. Cov hmoov ntws zoo: Cov hmoov me me dhau, cov hmoov me dhau yuav dais cov hmoov sib xyaw ua ke, streaming yuav tsis kis. Thaum txau rau ntawm qhov chaw ua haujlwm kom tsim tau ib qho sleek thiab me me, cuam tshuam rau txheej txheej. Thaum cov hmoov coarse heev rau cov hmoov chim yog tsis yooj yim fluidization.
4. Kev ruaj ntseg cia: Kev ruaj ntseg yog hais txog cov hmoov txheej nyob rau hauv tej yam kev mob, kom cov hmoov particle loj, zoo thiab hardness muaj peev xwm, piv txwv li, seb cov hmoov nyob rau hauv cia los yog siv yuav nqus noo noo, qhov tshwm sim ntawm phenomena xws li hmoov caking. Feem ntau cov hmoov zoo dua, tshwj xeeb tshaj yog cov hmoov ultrafine cov ntsiab lus tsawg dua 10μm ntau cov hmoov yooj yim nqus cov dej noo, cov pob txha pob txha, tsis muaj kev ruaj ntseg, yuav ntsaws rab phom, nti hmoov phem.
5. Tus nqi rov qab: hmoov txheej ntau lawm cog thiab hmoov txheej xim cog muaj qhov teeb meem ntawm kev rov ua dua cov hmoov txheej, feem ntau, cov hmoov txheej loj <10μm ultra-nplua hmoov rov qab yog tsawg, thaum cov hmoov nplej loj> 10μm pm hmoov txheej rov qab. tus nqi nce sai heev, thiab cov hmoov Cov nyiaj rov qab tau nce ntxiv thaum cov particle loj nce.

Hmoov txheej los ua qhov tseem ceeb ntawm qhov ntsuas particle loj yog tib cov qauv, kev taw qhia ntawm cov hmoov ntau lawm, kev ua haujlwm ntawm cov hmoov kom ua tiav qhov kev ua tau zoo tshaj plaws.
