Qhov siab ceev dua ntawm homogenizer, qhov zoo dua?

Homogenizer ua lub luag haujlwm tseem ceeb hauv kev sib xyaw ua ke ntawm cov khoom siv khoom lag luam, tshwj xeeb hauv kev sib xyaw ua kua-sib xyaw, kua-kua sib xyaw, roj-dej emulsification, dispersion thiab homogenization, shear sib tsoo. Yog vim li cas vim li cas nws hu ua emulsifying tshuab yog yuav tsum paub txog lub luag haujlwm ntawm emulsification. Tom qab ua tiav cov roj-dej ob-theem nruab nrab, cov emulsion yuav muab faib ua ob kab: roj hauv dej lossis roj hauv dej. Muaj tsawg kawg yog ob qho xav tau rau emulsification. Ua ntej tshaj, cov nyhuv dispersing ntawm kev txiav tshuab yog khaus, thiab cov kua nruab nrab yog txiav tib lub sijhawm nrog cov roj theem thiab tawg mus rau hauv qhov me me. Qhov ob yog qhov tsim nyog emulsifier, uas ua lub nruab nrab txuas nruab nrab ntawm cov roj thiab dej lwg me me. Los ntawm lub txim thiab intermolecular kev quab yuam, lub emulsion tuaj yeem khaws cia nyob rau hauv raws li lub sijhawm peb xav tau.

Cov nyhuv txiab ntawm emulsifying tshuab ncaj qha cuam tshuam rau qhov kawg kawg. Tom qab kev txheeb xyuas, nws feem ntau yog cuam tshuam nrog kev sib tsoo ntawm cov hniav, lub ntsej muag tawv tawv, kev tshem tawm ntawm rotor thiab stator, kev txheeb ze ntawm kev txav ceev ntawm ob txoj kab txiav thiab pub pom qhov loj me me. Feem ntau, qhov sib txawv ntawm cov hniav, lub ntsej muag tawv tawv, kev tshem tawm ntawm rotor thiab tso cai qhov loj me tau muab tso ua ntej lossis tsis xav hloov pauv qhov txheeb ze ntawm kev ceev ntawm lub rotor yog qhov cuam tshuam tshaj plaws, uas tau qhia raws li qhov ceev ntawm lub rotor. (vim tias tus stator yog nyob ruaj ruaj). Yog tias txoj kab nrawm nrawm dhau los, qhov txiav lossis cuam tshuam ntom ntawm cov hluav taws xob radial yuav ntws siab, yog li cov nyhuv refining yuav muaj zog, thiab rov ua dua. Txawm li cas los xij, qhov siab dua linear tshaj tawm, qhov zoo dua. Thaum nws nce mus txog tus nqi siab heev, muaj lub siab nyiam tiv thaiv qhov ntws (ib yam li ib tus tub rog uas muaj kev tshaj lij muaj peev xwm tig nws rab ntaj los tiv cov xib xub los ntawm lub hom phiaj). Yog li ntawd, tus nqi ntws mus los tsawg heev, thiab cov cua sov siab heev, thiab qee cov ntaub ntawv yuav sib sau ua ke, uas ua rau qhov tshwm sim tsis zoo.

Yog tus nplawm nplawm shear ceev? Cov neeg uas tau kawm physics hauv qib high school paub tias qhov nrawm nrawm yuav muab faib ua txoj kab sib luag ntawm lub kaum kev thiab kev nrawm. Shear nrawm ntawm chav kawm yog hais txog linear speed, thiab linear speed=lub kaum kev sib hloov × taub ular taub. Yog li ntawd, vim li cas qhov kev sib hloov ceev (lub kaum kev ceev) ntawm kev lag luam emulsifying feem ntau tsuas yog 3000rpm lossis 1500rpm, thaum uas ntawm lub tshuab kuaj emulsifying yog 10000rpm lossis 1500rpm Ntawm 280000rpm, ntawm txoj kab uas hla tau coj mus rau hauv tus account, thiaj li hais tias cov shear kab tshaj tawm ntawm ob yog ze, thiab cov nyhuv kawg yog los ze. Los ntawm lwm qhov kev pom, qhov kev ntsuas hauv chaw ntsuas yog yam ntxwv tsawg dua, yog li lub cev qhov loj ntawm lub rotor stator yuav tsum yoog rau qhov sib thooj me, lub taub yuav tsum yog me me. Txhawm rau ua kom muaj qhov tsis zoo ntawm qhov loj me ntawm txoj kab ceev, qhov ceev ntawm lub rotor yuav tsum tau nce, yog li tsim" kev kub ceev" ntawm qhov ntsuas ntsuas.

Nws tuaj yeem pom los ntawm cov saum toj no hais tias qhov kev sib hloov ceev (lub nrawm nrawm) ntawm lub tshuab emulsifying yuav tsum txiav txim siab ua ke nrog cov peev txheej kho tau tiag tiag.
