Ungawukhetha njani umatshini ofanelekileyo wokulinganisa, iJamani ingenisa ngaphandle umatshini wokumilisela, umatshini wokufaka umzobo wemizi mveliso, umatshini wokulinganisa umqhubi wenqwelomoya.
Umatshini we-Emulsifying udlala indima ebalulekileyo kwinkqubo yokuxuba izixhobo zemizi-mveliso, ngakumbi kumxube oqinileyo wolwelo kunye nolwelo.
Ukuxuba ulwelo, i-oyile-amanzi emulsification, ukusabalalisa kunye ne-homogenization, ukugaya i-shear kunezicelo ezibaluleke kakhulu.Isizathu
Kubizwa ngokuba ngumatshini wokumisela ngenxa yokuba unokufikelela kwi-emulsification.Yenziwe emva kokuxutywa okupheleleyo kweoli kunye namanzi aphakathi kwesigaba sesibini
I-Emulsion inokwahlukana kwiinkqubo ezimbini: ioli emanzini okanye ioli emanzini.Ukufezekisa i-emulsification, kukho ubuncinane iimfuno ezimbini:
Enye yimpembelelo eyomeleleyo yokusika i-mechanical cut dispersion, isigaba samanzi kunye nesigaba se-oyile se-fluid medium ngexesha elinye elisikiwe kwaye lisasazeke kancinci.
Amacandelo, kwaye emva koko adibanise xa kukho ukuxubana ngokungena ngaphakathi, ukubunjwa kwe-emulsion.Emibini yi-emulsifier efanelekileyo,
Isebenza njengebhulorho ephakathi phakathi kweoyile kunye neamolekyuli zamanzi, kwaye yenza ioyile kunye namanzi ngokusebenza kwentlawulo yombane kunye namandla e-intermolecular.
I-emulsion iya kuzinza ixesha elide njengoko sifuna.
Ngoku ukusetyenziswa komatshini wokumisela akuphelelanga nje “kwi-emulsification”, ngenxa yesenzo sayo esikhethekileyo sokucheba,
Amasuntswana ahlanjululweyo kwimpembelelo yolwelo ekugqibeleni asulungekiswa kubungakanani obufanelekileyo bamasuntswana, ukuze izinto eziqinileyo zixutywe ngokupheleleyo.
Kwi-liquid kunye nokwenza ukumiswa okuzinzileyo, le nkqubo ikwabizwa ngokuba yi "dispersion".Kwaye ngokuqinisekileyo kunye ne-emulsification
Njenge-dispersant, ukuzinza kokunqunyanyiswa kunokongezwa ngokudibanisa i-dispersant.Xa into eqinileyo
Inokunyibilikiswa ngokupheleleyo lulwelo ngexesha elithile lokudibana nolwelo, emva koko, yenziwe yimpembelelo yokucheba
Amasuntswana amancinci aya kunyibilika ngokukhawuleza kuba indawo yawo ethile ingaphezulu ngokuphindwe kaninzi.
Xa abantu besetyenziselwa i-homogenizer yoxinzelelo oluphezulu (uxinzelelo, uxinzelelo oluphezulu ngokukhawuleza, impembelelo yejethi) ukufumana
Emva kokufumana amasuntswana alungileyo, "ukucoca" ilingana "homogenization", ngoko ke i-emulsifier ilungile kwizinto eziphathekayo.
Inkqubo ye-homogenization kunye nokuxuba ngokupheleleyo kubizwa ngokuba yi-homogenization.Ngoko ke, sinokubeka i-emulsifier
Ebizwa ngokuba yi-homogenizer, ukuze ukwahlula, ngokubanzi kunokuba sisithsaba kwisantya esiphezulu okanye kwi-homogenizer ephezulu yokucheba, ukuze ubisi
Umatshini weChemical unamagama amaninzi: umatshini wokucheba ophezulu we-emulsification, umatshini wokucheba ophezulu we-homogenization, umatshini wokucheba ophezulu wokusasazwa kwe-emulsification, ephezulu
Shear i-emulsifier elinganayo, i-emulsifier yokucheba ephezulu ene-homogeneous dispersion emulsifier,...
Izinto ezichaphazela i-emulsification
1. Izixhobo zokulinganisa
Okwangoku, kukho iintlobo ezintathu eziphambili zomatshini wokufaka i-emulsifying: i-emulsifying mixer, i-colloid mill kunye ne-homogenizer.Uhlobo lomatshini we-Emulsifying kunye nesakhiwo, ukusebenza kunye nobukhulu beengqungquthela ze-emulsion (ukusabalalisa) kunye nomgangatho we-emulsion (uzinzo) unobudlelwane obukhulu.I-emulsion eveliswa yi-emulsifier ephazamisayo ine-dispersibility embi, amasuntswana amakhulu kunye arhabaxa, uzinzo olubi kunye nongcoliseko olulula.Kodwa ukuveliswa kwayo kulula, ixabiso liphantsi, nje ukuba unike ingqalelo kwisakhiwo esifanelekileyo somatshini, sebenzisa ngokufanelekileyo, kodwa unokuvelisa iimfuno zomgangatho odibeneyo wezinto zokuthambisa ezidumileyo.I-Colloid Mill kunye ne-homogenizer zizixhobo ezingcono zokumisela.Kwiminyaka yakutshanje, oomatshini be-emulsifying benze inkqubela phambili enkulu, njengomatshini wokucoca i-vacuum, ukusabalalisa kunye nokuzinza kwe-emulsion elungiselelwe yiyo kuhle kakhulu.
2, ubushushu
Ubushushu be-Emulsification bunempembelelo enkulu kumgangatho we-emulsification, kodwa akukho mda ungqongqo kwiqondo lokushisa.Ngokuqhelekileyo, ngexesha lokufakwa kwe-emulsification, ubushushu bezigaba ze-oyile kunye namanzi bunokulawulwa phakathi kwe-75 ℃ kunye ne-85 ℃.Oku kuxhomekeke kwizinto ezifana nendawo yokunyibilika kwezinto ezinendawo ephezulu yokunyibilika, uhlobo lwe-emulsifier kunye nokunyibilika kwesigaba seoli kunye nesigaba samanzi.
3. Ukulinganisa ixesha
Ixesha le-Emulsification linempembelelo kumgangatho we-emulsion.Ubude bexesha le-emulsifying lihambelana nomlinganiselo womthamo wesigaba seoli kunye nesigaba samanzi, i-viscosity yezigaba ezibini kunye ne-viscosity ye-emulsion eyenziwe, uhlobo kunye ne-dosage ye-emulsifier, ukushisa kwe-emulsifying, uhlobo lwe-emulsifier kunye nezinye izinto.Ngokuqhelekileyo kugqitywa ngamava kunye novavanyo.
