Los ntawm cov kua nplaum sib nqus tsim nyob rau hauv qhov kev txiav txim ntawm lub magnetic teb, cov khoom tsis sib nqus abrasive raug tshem tawm hauv nws tuaj yeem raug nias tawm tsam qhov kev sib hloov ua haujlwm rau kev sib tsoo thiab polishing nyob rau hauv qhov kev txiav txim ntawm lub zog ntws thiab buoyancy ntawm cov kua nplaum sib nqus, yog li txhim kho cov khoom sib nqus. zoo thiab efficiency ntawm finishing. Nws tuaj yeem tau txais qhov chaw ua haujlwm nrog Ra tsawg dua lossis sib npaug rau 0.01μm yam tsis muaj txheej txheem metamorphic, thiab tuaj yeem polish workpieces nrog cov duab ntawm cov duab. Vim tias cov kab sib nqus ntawm cov hlau nplaum thiab cov kua nplaum sib nqus tsim los ntawm lawv tsis ncaj qha koom nrog kev tshem tawm cov ntaub ntawv, nws yog hu ua magnetic field-pab processing.
Cov kua nplaum sib nqus yog tsim los ntawm cov khoom sib nqus, cov khoom siv hluav taws xob thiab cov khoom siv ua kua (xws li dej, roj, thiab lwm yam). Qhov nruab nrab qhov me me ntawm cov khoom sib nqus yog li 10urn, uas yog nyob ib puag ncig los ntawm cov organic molecules ntawm cov surfactants ruaj khov, thiab dhau los ua cov khoom sib nqus ruaj khov colloid, tshem tawm hauv cov roj los yog cov kua dej ua kua. Piv txwv li, CY3-1 hlau magnetic fluid yog ua los ntawm Fe3O4 cov khoom sib nqus (feem ntau 10 feem pua -30 feem pua) nrog ib tug particle txoj kab uas hla ntawm 7.5-10nm, dispersed nyob rau hauv ntxhia roj nrog surfactant oleic acid (qhov loj ntawm 40 feem pua -60 feem pua ) Nyob rau hauv cov cab kuj, nws saturation induction siv yog 0.023T, ceev yog 1.2g/mL, thiab dynamic viscosity yog 20 × 10-3Pa·s. Vim hais tias lub sij hawm sib nqus ntawm cov hlau nplaum yog qhov loj heev, lawv yuav tsis raug precipitated los ntawm lub ntiajteb txawj nqus, thiab lawv cov magnetization nkhaus tsis muaj hysteresis, thiab cov hlau nplaum tuaj yeem nce ntxiv nrog rau qhov nce ntawm qhov sib nqus ntawm lub zog, thiaj li paub txog kev tswj ntawm cov hlau nplaum. workpiece quab yuam thiab tus nqi ua.
Cov txheej txheem sib nqus sib nqus no tau tshwm sim hauv Tebchaws Meskas hauv xyoo 1940s, thiab tau tsim los ntawm cov kws tshawb fawb hauv qub Soviet Union thiab Bulgaria thaum xyoo 1950 thiab thaum ntxov 1960s. Los ntawm xyoo 1970, nws tau pom tias cov cuab yeej siv no tuaj yeem siv rau hauv kev ua tiav ntawm feem ntau cov khoom hnyav. Txij li thaum xyoo 1980s lig, Nyiv tau kawm ntxiv txog nws cov txheej txheem thiab cov khoom siv, thiab nws daim ntawv thov hauv kev ua tiav tau tsim. Nyob rau xyoo 1990, cov kws tshawb fawb hauv Nyij Pooj, Tebchaws Askiv thiab Tebchaws Meskas txuas ntxiv nthuav dav nws cov cuab yeej siv tshuab thiab khoom siv. Thiab zoo meej, thiab siv cov txheej txheem finite los simulate cov txheej txheem sib nqus polishing, txheeb xyuas cov yam ntxwv ntawm cov dej sib nqus thiab cov khoom abrasive nyob rau hauv magnetic induction, uas txhawb kev loj hlob thiab kev siv ntawm cov txheej txheem no.
