1. Imishini ye-Emulsification Imishini yokulungisa i-emulsion ngokuyinhloko i-emulsifier, okuwuhlobo lwemishini yokugcwalisa exuba uwoyela namanzi ngokulinganayo.Njengamanje, kunezinhlobo ezintathu eziyinhloko zama-emulsifiers: i-emulsification mixer, i-colloid mill ne-homogenizer.Uhlobo, ukwakheka nokusebenza kwe-emulsifier kunobudlelwano obukhulu nobukhulu (ukuhlakazeka) kwezinhlayiya ze-emulsion kanye nekhwalithi (ukuzinza) kwe-emulsion.Ngokuvamile, njenge-emulsifier eshukumisayo esasetshenziswa kabanzi ezimbonini zezimonyo, i-emulsion elungisiwe inokuhlakazeka okubi.Izinhlayiya zinkulu futhi zimahhadlahhadla, azizinzile, futhi zivame ukungcoliswa.Nokho, ukukhiqizwa kwayo kulula futhi intengo ishibhile.Uma nje ukhetha ukwakheka okunengqondo komshini futhi uwusebenzise ngendlela efanele, ungaphinda ukhiqize izimonyo ezidumile ezinezidingo zekhwalithi ezihlanganisiwe ezijwayelekile.Eminyakeni yamuva, umklamo we-Vacuum Mixer Homogenizer wenze intuthuko enkulu, futhi i-emulsion elungiselelwe i-Vacuum Mixer Homogenizer design inokuhlakazeka okuhle kakhulu nokuzinza.
2. Izinga Lokushisa Ukushisa kwe-emulsification kunethonya elikhulu kwikhwalithi ye-emulsification, kodwa akukho mkhawulo oqinile ekushiseni.Uma amafutha namanzi kokubili kuwuketshezi, i-emulsification ingafinyelelwa ngokushukumisa ekamelweni lokushisa.Ngokuvamile, izinga lokushisa le-emulsification lincike endaweni yokuncibilika kwento encibilika kakhulu equkethwe ezigabeni ezimbili, futhi ibheka izici ezifana nohlobo lwe-emulsifier kanye nokuncibilika kwesigaba sikawoyela kanye nesigaba samanzi.Ukwengeza, izinga lokushisa lalezi zigaba ezimbili lidinga ukugcinwa licishe lifane, ikakhulukazi ezingxenyeni zesigaba se-wax namafutha ezinamaphoyinti ancibilikayo aphezulu (ngaphezu kuka-70 ° C), lapho i-emulsification, isigaba samanzi sokushisa esiphansi asinakwengezwa ukuvimbela I-wax, Amafutha acwebezela aphume, okuholela ekubeni kube nezigaxa noma ezimahhadla, ama-emulsions angalingani.Ngokuvamile, ngesikhathi sokwenziwa kwe-emulsification, izinga lokushisa likawoyela nezigaba zamanzi lingalawulwa phakathi kuka-75°C no-85°C.Uma isigaba samafutha siqukethe i-wax ephezulu yokuncibilika nezinye izingxenye, izinga lokushisa le-emulsification lizoba phezulu ngalesi sikhathi.Ukwengeza, uma i-viscosity ikhula kakhulu ngesikhathi senqubo ye-emulsification, okuthiwa yi-thick too thick futhi ithinta ukugqugquzela, izinga lokushisa le-emulsification lingakhuphuka ngokufanele.Uma i-emulsifier esetshenzisiwe inezinga elithile lokushisa lokuguqulwa kwesigaba, izinga lokushisa le-emulsification nalo likhethwa ngokuzungezile eduze nezinga lokushisa lesigaba.Ukushisa kwe-emulsification nakho ngezinye izikhathi kunomphumela kusayizi wezinhlayiyana ze-emulsion.Isibonelo, lapho i-fatty acid soap emulsifier ye-anionic emulsifier isetshenziselwa ukufakwa kwe-emulsification ngendlela yensipho eyinhloko, lapho izinga lokushisa lokufakwa kwe-emulsification lilawulwa ku-80 °C, usayizi wezinhlayiyana ze-emulsion cishe ngu-1.8-2.0 μm.Uma i-emulsification yenziwa ku-60 °C, usayizi wezinhlayiyana cishe u-6 μm.Uma emulsifiers nge-nonionic emulsifiers, umthelela we-emulsification wezinga lokushisa kusayizi wezinhlayiyana awunamandla.
3. Isikhathi se-Emulsification seI-Vacuum Mixer Homogenizerukuklama Isikhathi se-emulsification ngokusobala sinethonya kwikhwalithi ye-emulsion, futhi ukuzimisela kwesikhathi se-emulsion kusekelwe kumthamo wesilinganiso sesigaba samafutha kanye nesigaba samanzi, i-viscosity yezigaba ezimbili kanye ne-viscosity ye-emulsion ewumphumela. , uhlobo kanye nenani le-emulsifier, Kukhona futhi izinga lokushisa le-emulsification, kodwa isikhathi se-emulsification siwukwenza isistimu ifakwe ngokugcwele, ehlobene eduze nokusebenza kahle kwemishini ye-emulsification.Isikhathi se-emulsification singanqunywa ngokuya ngolwazi nokuhlolwa.Uma i-homogenizer (3000 rpm) isetshenziselwa i-emulsification, kuthatha imizuzu engu-3-10 kuphela.
4. Isivinini esishukumisayo Imishini ye-Emulsification inethonya elikhulu ekufakweni kwe-emulsification, okukodwa okuwumphumela wokugqugquzela isivinini ku-emulsification.Ijubane elishukumisayo lilinganiselwe ukwenza isigaba samafutha kanye nesigaba samanzi sixutshwe ngokugcwele, futhi isivinini esishukumisayo siphezulu kakhulu
5. Isivinini esinyakazayo seI-Vacuum Mixer Homogenizer idizayini inethonya elikhulu emulsification, elinye lawo ithonya isivinini enyakazayo on emulsification.Isivinini esimaphakathi esishukumisayo siwukwenza isigaba samafutha kanye nesigaba samanzi sixutshwe ngokugcwele.Uma ijubane elishukumisayo liphansi kakhulu, inhloso yokuxuba okugcwele ngeke ifezeke.Kodwa-ke, uma isivinini esishukumisayo siphezulu kakhulu, amabhamuza omoya azolethwa ohlelweni, okulenze libe uhlelo lwezigaba ezintathu.Yenza ama-emulsions angazinzi.Ngakho-ke, ukungena komoya kufanele kugwenywe ngesikhathi sokunyakaziswa, futhi i-vacuum emulsifier inokusebenza okuhle kakhulu.
I-Smart Zhitong inesipiliyoni seminyaka eminingi ekuthuthukisweni, klama i-Vacuum Mixer HomogenizerI-Vacuum Homogenizer Mixerkanye nomthamo womshini kusuka ku-5L kuya ku-18000L
Uma kukhona okukukhathazayo sicela uthinte
