Momwe mungasankhire makina oyenera opangira ma emulsifying, makina opangira ma emulsifying aku Germany, makina opangira mafakitale, makina oyendetsa ndege
Makina opangira emulsifying amagwira ntchito yofunika kwambiri pakusakaniza zida zamafakitale, makamaka pakusakaniza kwamadzimadzi ndi madzi.
Kusakaniza kwamadzimadzi, emulsification yamadzi-mafuta, kubalalitsidwa ndi homogenization, kumeta ubweya wa ubweya kumakhala ndi ntchito zofunika kwambiri. Chifukwa chake
Imatchedwa emulsifying makina chifukwa akhoza kukwaniritsa emulsification. Anapangidwa pambuyo wathunthu kusakaniza mafuta ndi madzi awiri gawo sing'anga
Emulsion akhoza kugawidwa m'magulu awiri: mafuta m'madzi kapena mafuta m'madzi. Kuti mukwaniritse emulsification, pali zofunikira ziwiri:
Imodzi ndi amphamvu mawotchi kudula dispersion zotsatira, madzi gawo ndi mafuta gawo la sing'anga madzimadzi nthawi yomweyo kudula ndi kumwazikana kwa ang'onoang'ono.
Tinthu, ndiyeno coalesce pamene pali mwalowa kulowa kusanganikirana, mapangidwe emulsion. Awiri ndi emulsifier yoyenera,
Imakhala ngati mlatho wapakati pakati pa mamolekyu amafuta ndi madzi, ndipo imapanga mafuta ndi madzi pogwiritsa ntchito mphamvu yake yamagetsi ndi mphamvu ya intermolecular.
The emulsion adzakhala wokhazikika kwa nthawi yonse yomwe tikufuna.
Tsopano kugwiritsa ntchito makina opangira emulsifying sikungokhala "emulsification", chifukwa cha kumeta ubweya wapadera, pa
Pulverized particles mu madzi zimakhudza pamapeto pake woyengedwa kwa abwino tinthu kukula, kotero kuti olimba zakuthupi mokwanira wosanganiza
Mumadzimadzi ndikupanga kuyimitsidwa kokhazikika, njirayi imatchedwanso "kubalalitsidwa". Ndipo ndithudi ndi emulsification
Mofanana ndi dispersant, kukhazikika kwa kuyimitsidwa kumatha kukulitsidwa powonjezera dispersant. Pamene chinachake cholimba
Akhoza kwathunthu kusungunuka ndi madzi mwa nthawi ina kukhudzana ndi madzi, ndiye, popangidwa ndi kukameta ubweya zimakhudza
Tizigawo tating'onoting'ono timasungunuka mwachangu chifukwa malo awo enieni amakhala okulirapo nthawi zambiri.
Anthu akamagwiritsidwa ntchito ku homogenizer yapamwamba (kuponderezana, kutulutsa nthawi yomweyo, kuthamanga kwa ndege) kuti apeze
Mutapeza tinthu tating'onoting'ono, "kuwongolera" ndikufanana ndi "homogenization", kotero emulsifier ndiyabwino pazinthuzo.
Njira ya homogenization ndi kusakaniza kwathunthu imatchedwanso homogenization. Chifukwa chake, titha kuyikanso emulsifier
Otchedwa homogenizer, pofuna kusiyanitsa, kawirikawiri akhoza kukhala korona mu liwilo kapena mkulu kukameta ubweya homogenizer, kuti mkaka.
Makina opangira mankhwala ali ndi mayina ambiri: makina apamwamba ometa ubweya wa ubweya, makina apamwamba ometa ubweya homogenization, makina apamwamba ometa ubweya wobalalika emulsification, apamwamba
Kumeta ubweya homogeneous emulsifier, mkulu kukameta ubweya homogeneous kubalalitsidwa emulsifier, ...
Zinthu zomwe zimakhudza emulsification
1. Emulsifying zida
Pakali pano, pali mitundu itatu ikuluikulu ya makina emulsifying: emulsifying chosakanizira, colloid mphero ndi homogenizer. Emulsifying makina mtundu ndi dongosolo, ntchito ndi kukula kwa emulsion particles (kubalalitsidwa) ndi khalidwe la emulsion (bata) ali ndi ubale waukulu. The emulsion opangidwa ndi agitating emulsifier ali dispersibility osauka, lalikulu ndi coarse particles, osauka bata ndi mosavuta kuipitsa. Koma kupanga kwake n'kosavuta, mtengo wake ndi wotchipa, malinga ngati mumayang'anitsitsa kapangidwe kake ka makina, gwiritsani ntchito bwino, komanso mukhoza kupanga zofunikira zambiri zamtundu wa zodzoladzola zotchuka. Colloid mphero ndi homogenizer ndi bwino emulsifying zida. M'zaka zaposachedwapa, emulsifying makina wapita patsogolo kwambiri, monga zingalowe emulsifying makina, kubalalitsidwa ndi bata la emulsion anakonza ndi zabwino kwambiri.
2, kutentha
Kutentha kwa emulsification kumakhudza kwambiri khalidwe la emulsification, koma palibe malire okhwima pa kutentha. Nthawi zambiri, pa emulsification, kutentha kwa magawo amafuta ndi madzi kumatha kuwongoleredwa pakati pa 75 ℃ ndi 85 ℃. Izi zimatengera zinthu monga kusungunuka kwa zinthu zomwe zimakhala ndi malo osungunuka kwambiri, mtundu wa emulsifier ndi kusungunuka kwa gawo lamafuta ndi gawo lamadzi.
3. Emulsifying nthawi
Emulsification nthawi zimakhudza khalidwe la emulsion. Kutalika kwa emulsifying nthawi kumakhudzana ndi kuchuluka kwa kuchuluka kwa gawo la mafuta ndi gawo lamadzi, kukhuthala kwa magawo awiri ndi kukhuthala kwa emulsion yopangidwa, mtundu ndi mlingo wa emulsifier, kutentha kwa emulsifying, mtundu wa emulsifier ndi zinthu zina. Kawirikawiri zimatsimikiziridwa ndi zochitika ndi kuyesa.
4, kusakaniza liwiro
Liwiro losakaniza liyenera kukhala lokwanira
