LUB PRINCIPLE NTAWM ULTRASONIC EMULSIFICATION
Phacoemulsification hais txog tus txheej txheem uas ob (lossis ntau tshaj ob) kua dej tsis sib xyaw kom sib tov ua ib qho kev sib qis hauv kev ua haujlwm ntawm ultrasonic lub zog, thiab ib hom kua muaj sib npaug hauv lwm cov kua los ua ib qho emulsion.
Ultrasonic emulsification muaj cov nram qab no nta piv rau kev emulsification kev sib xyaw thiab khoom siv (xws li cav, sib tsoo mills, homogenizers, thiab lwm yam):
1. Cov khoom zoo siab emulsification
Lub resulting emulsion muaj me me nruab nrab droplet me me ntawm 0.2 rau 2 μ m, nqaim droplet loj tis ntau ntawm 0.1 rau 10 μ m lossis tsawg dua, lub siab concentration, ntshiab emulsion concentration txog li 30%, thiab ib emulsifier txog mus rau 70%. .
2. Kev ruaj ntseg ntawm emulsion
Emulsifiers yuav siv tau los tsis muaj los yog tsawg dua los tsim ib qho emulsion ruaj khov, thiab qee tus yuav ua tau ruaj khov rau lub hlis ntau tshaj 6 lub hlis, muaj tsawg zog kev noj haus, cov khoom ua tau zoo, thiab cov nqi tsawg dua.
3. Tswj lub hom emulsion
Hauv qee lub suab nrov, ob qho o / w (roj-hauv-dej) thiab w / o (dej-hauv-roj) emulsions yuav npaj tau. Txawm li cas los, qhov no yuav tsis tau nrog cov neeg kho tshuab emulsification. Tsuas yog qhov ntawm lub emulsifier tswj tau cov kua xaim lactic acid. Hom ntawm. Piv txwv, thaum toluene emulsified hauv dej, ib hom emulsion tau tsim nyob rau hauv cov suab tsis tshua muaj suab, thaum lwm hom emulsion tau tsim nyob rau hauv lub suab siab khov.
4. Tsawg zog yuav tsum tsim emulsion
Xws li: kev npaj ntawm 4.55m3 / h, nco qhov siab ntawm 1μm emulsion, yog hais tias tus xuav xuav, thaum lub siab ua haujlwm 10.5 ~ 14.1kg / cm2, tsuas yog 5 mus rau 7 horsepower tsav zog, thiab siv high pressure homogenizer Thaum kev ua haujlwm siab yog 70.3 rau 351.6 kg / cm2, 40 mus rau 50 horsepower yog yuav tsum tau txhaj.
Phacoemulsification tuaj yeem tsim emulsions uas tsis tuaj yeem tau txais txhua yam los ntawm txoj kev dav dav. Piv txwv, zoo tib yam nplaum tsuas ua tau 5% siv quav dab tsi hauv dej, thiab hauv lub suab teb, 20% paraffin emulsion tuaj yeem tau txais. Roj roj phacoemulsification, combustion.
Tau tau nce thiab thov hauv lub teb chaws tau ntau xyoo. Nyob rau hauv txoj kev no, tsis muaj cov emulsifiers uas yuav tsum tau, thiab cov dej me me ntawm cov roj dej hauv cov roj emulsified yog 1μm, thiab cov txuag hluav taws xob yog 6% mus rau 25%, 40% mus 90% ntawm cov khoom noj kom tsawg, thiab cov nyhuv kev txo cov NOx 20% mus rau 75% yog tau tiav. Ntxiv cov dej me me rau roj kerosene roj rau phacoemulsification thiab nws yuav ua tau kom muaj kev txwv tsis pub muaj lub kerosene, muaj ntau tshaj 40% ntawm cov roj, uas yog yooj yim rau kev cia thiab tsheb thauj mus los, thiab muaj cov txiaj ntsim zoo. Ntawm qhov tod tes, ultrasound tau demulsify emulsions ntawm tsawg lub suab qib thiab frequencies.
Yuav nrhiav tau ib homogenizer ultrasonic rau koj siv.
