Ungawukhetha kanjani umshini wokugcwalisa ofanele, iJalimane ingenise umshini wokufaka i-emulsifying, umshini wokugcwalisa izimboni, umshini wokufaka umshayeli wendiza
Umshini wokugcwalisa i-emulsifying udlala indima ebalulekile ohlelweni lokuxuba imishini yezimboni, ikakhulukazi ekuxubeni okuqinile koketshezi noketshezi.
Ukuxuba uketshezi, i-oyela-amanzi emulsification, ukusabalalisa kanye ne-homogenization, ukugaya i-shear kunezinhlelo zokusebenza ezibaluleke kakhulu.Isizathu
Kubizwa ngokuthi umshini wokugcwalisa i-emulsifying ngoba ungafinyelela ukufakwa kwe-emulsification.Yakheka ngemva kokuhlanganiswa okuphelele kwamafutha namanzi okuphakathi kwesigaba sesibili
I-emulsion ingahlukaniswa ngezinhlelo ezimbili: amafutha emanzini noma amafutha emanzini.Ukufeza i-emulsification, kunezidingo okungenani ezimbili:
Enye iwumphumela wokuhlakazeka okuqinile komshini wokusika, isigaba samanzi nesigaba sikawoyela se-fluid medium ngesikhathi esifanayo asikwe futhi asakazwe kancane.
Izinhlayiya, bese zihlangana lapho kukhona ukuxubana kokungena ngaphakathi, ukwakheka kwe-emulsion.Okubili yi-emulsifier efanele,
Isebenza njengebhuloho eliphakathi phakathi kwama-molecule kawoyela namanzi, futhi yenza uwoyela namanzi ngokusebenzisa isenzo sokushaja kwawo kagesi namandla e-intermolecular.
I-emulsion izozinza isikhathi eside njengoba sifuna.
Manje ukusetshenziswa komshini we-emulsifying akugcini nje kuphela "emulsification", ngenxa yesenzo sawo esiyingqayizivele sokugunda,
Izinhlayiya eziputshuziwe emthelela owuketshezi ekugcineni zicwengisiswe zibe usayizi wezinhlayiyana ezifanele, ukuze okuqinile kuxutshwe ngokugcwele.
Ku-liquid futhi kwakha ukumiswa okuzinzile, le nqubo yaziwa nangokuthi "ukuhlakazeka".Futhi-ke nge-emulsification
Njenge-dispersant, ukuzinza kokumiswa kungathuthukiswa ngokungeza i-dispersant.Lapho into eqinile
Ingancibilika ngokuphelele uketshezi ngokusebenzisa isikhathi esithile ukuxhumana ketshezi ke, ezakhiwe umthelela phuca
Izinhlayiya ezincane zizoncibilika ngokushesha ngoba indawo yazo ethile inkulu ngokuphindwe kaningi.
Lapho abantu besetshenziselwa i-homogenizer yomfutho ophezulu (ukucindezela, ukukhishwa ngokushesha komfutho ophezulu, umthelela wejethi) ukuze bathole
Ngemuva kokuthola izinhlayiya ezinhle, "ukucwengisiswa" kulingana "ne-homogenization", ngakho-ke i-emulsifier ilungile ezintweni
Inqubo ye-homogenization kanye nokuxuba okugcwele kubizwa nangokuthi i-homogenization.Ngakho-ke, singaphinda sibeke i-emulsifier
Ebizwa ngokuthi i-homogenizer, ukuze uhlukanise, ngokuvamile ingaba umqhele ngesivinini esiphezulu noma i-shear homogenizer, ukuze ubisi
Umshini wamakhemikhali unamagama amaningi: umshini we-shear emulsification ophezulu, umshini we-shear high homogenization, umshini we-shear wokuhlakazeka wokuhlakazeka okuphezulu
I-Shear emulsifier ene-homogeneous, i-shear ephezulu yokuhlakazeka kwe-emulsifier,...
Izinto ezithinta i-emulsification
1. Emulsifying imishini
Njengamanje, kunezinhlobo ezintathu eziyinhloko zomshini we-emulsifying: i-emulsifying mixer, i-colloid mill ne-homogenizer.Uhlobo lomshini we-Emulsifying kanye nesakhiwo, ukusebenza kanye nobukhulu bezinhlayiya ze-emulsion (ukuhlakazeka) kanye nekhwalithi ye-emulsion (ukuzinza) kunobudlelwane obukhulu.I-emulsion ekhiqizwa i-emulsifier enyakazayo inokuhlakazeka okubi, izinhlayiya ezinkulu nezimahhadla, ukuzinza okubi kanye nokungcola okulula.Kodwa ukukhiqizwa kwayo kulula, intengo ishibhile, inqobo nje uma unaka isakhiwo esinengqondo somshini, sebenzisa kahle, kodwa futhi ingaveza izidingo zekhwalithi ezihlanganisiwe zezimonyo ezithandwayo.Isigayo se-Colloid ne-homogenizer ziyimishini engcono yokuhlanganisa.Eminyakeni yamuva, imishini yokufaka i-emulsion yenze intuthuko enkulu, njengomshini we-vacuum emulsifying, ukuhlakazeka nokuzinza kwe-emulsion elungiselelwe yikho kuhle kakhulu.
2, izinga lokushisa
Ukushisa kwe-Emulsification kunethonya elikhulu kukhwalithi ye-emulsification, kodwa akukho mkhawulo oqinile kumazinga okushisa.Ngokuvamile, ngesikhathi se-emulsification, izinga lokushisa likawoyela nezigaba zamanzi lingalawulwa phakathi kuka-75 ℃ no-85 ℃.Lokhu kuncike ezintweni ezifana nephoyinti lokuncibilika lezinto ezinephuzu eliphezulu lokuncibilika, uhlobo lwe-emulsifier nokuncibilika kwesigaba sikawoyela nesigaba samanzi.
3. Isikhathi Emulsifying
Isikhathi se-Emulsification sinomthelela kwikhwalithi ye-emulsion.Ubude besikhathi se-emulsifying buhlobene nesilinganiso somthamo wesigaba samafutha kanye nesigaba samanzi, i-viscosity yezigaba ezimbili kanye ne-viscosity ye-emulsion ekhiqiziwe, uhlobo nomthamo we-emulsifier, izinga lokushisa emulsifying, uhlobo lwe-emulsifier nezinye izici.Ngokuvamile kunqunywa isipiliyoni nokuhlola.
4, ukuxuba isivinini
Isivinini sokuxuba kufanele sibe sanele
