1. Qalabka Emulsification Qalabka makaanikada ah ee lagu diyaariyo emulsion wuxuu u badan yahay emulsifier, kaas oo ah nooc ka mid ah qalabka emulsifier-ga oo si siman u walaaqaya saliidda iyo biyaha. Waqtigan xaadirka ah, waxaa jira saddex nooc oo emulsifiers ah: isku-dhafka emulsification, mill kolloid iyo homogenizer. Nooca, qaab-dhismeedka iyo waxqabadka emulsifier-ku waxay leeyihiin xidhiidh weyn oo leh cabbirka (dispersibility) ee qaybaha emulsion iyo tayada (dejinta) emulsion-ka. Guud ahaan, sida emulsifier-ka walaaqaya oo weli si weyn loogu isticmaalo warshadaha qurxinta, emulsion-ka la diyaariyey ayaa kala firdhisanaan liidata. Qaybaha waa waaweyn yihiin oo qallafsan yihiin, deggan yihiin, oo aad ugu nugul wasakhowga. Si kastaba ha ahaatee, soosaarkeedu waa sahlan yahay qiimuhuna waa raqiis. Ilaa inta aad doorato qaab-dhismeedka macquulka ah ee mashiinka oo aad si habboon u isticmaasho, waxay sidoo kale soo saari kartaa qurxinta caanka ah ee shuruudaha tayada guud ee isku dhafan. Sanadihii ugu dambeeyay, Vacuum Mixer Homogenizer design wuxuu sameeyay horumar weyn, iyo emulsion-ka ay diyaarisay Vacuum Mixer Homogenizer design wuxuu leeyahay kala firdhisanaan iyo xasillooni heer sare ah.
2. Heerkulka Heerkulka emulsification wuxuu saameyn weyn ku leeyahay tayada emulsification, laakiin ma jiro xad adag oo heerkulka ah. Haddii saliidda iyo biyuhu labaduba yihiin dareere, emulsification waxaa lagu gaari karaa walaaqaya heerkulka qolka. Guud ahaan, heerkulka emulsification wuxuu ku xiran yahay meesha ay dhalaalayso walaxda dhalaalaysa ee ku jirta labada weji, sidoo kale waxay tixgelisaa arrimo ay ka mid yihiin nooca emulsifier-ga iyo milanka wajiga saliidda iyo wajiga biyaha. Intaa waxaa dheer, heerkulka labada weji wuxuu u baahan yahay in lagu hayo isku mid, gaar ahaan qaybaha wajiga dhuka iyo dufanka leh dhibco dhalaalid sare ah (ka sarreeya 70 ° C), marka emulsification, heerkulka hoose ee biyaha laguma dari karo si looga hortago wax, Dufanku wuu soo baxaa, taasoo keenta buro ama qallafsan, emulsions aan sinnayn. Guud ahaan, inta lagu jiro emulsification, heerkulka saliidda iyo wejiyada biyaha waxaa lagu xakameyn karaa inta u dhaxaysa 75 ° C iyo 85 ° C. Haddii marxaladda saliidda ay ka kooban tahay wax dhibic dhalaalaysa sare iyo qaybo kale, heerkulka emulsification noqon doonaa sare waqtigan. Intaa waxaa dheer, haddii viscosity si weyn u kordho inta lagu guda jiro habka emulsification, waxa loogu yeero aad u qaro weyn oo saameeya walaaqaya, heerkulka emulsification si habboon loo kordhin karaa. Haddii emulsifier-ka la isticmaalay uu leeyahay heerkul rogan waji gaar ah, heerkulka emulsification ayaa sidoo kale la door bidaa heerkulbeeg rogan wajiga Heerkulka emulsification ayaa sidoo kale mararka qaarkood saameyn ku leh xajmiga walxaha emulsion-ka. Tusaale ahaan, marka emulsifier-ka saabuunta asiidhka dufanka leh loo isticmaalo emulsification habka saabuunta aasaasiga ah, marka heerkulka emulsification la xakameeyo 80 °C, cabbirka walxaha emulsionku waa qiyaastii 1.8-2.0 μm. Haddii emulsification lagu sameeyo 60 °C, cabbirka qurubku wuxuu ku saabsan yahay 6 μm. Marka lagu daro emulsifiers nonionic, saamaynta heerkulka emulsification ee cabbirka walxaha waa daciif.
3. Waqtiga Emulsification eeVakuum Mixer Homogenizerdesign Waqtiga emulsification si cad ayaa saamayn ku tayada emulsion ah, iyo go'aaminta waqtiga emulsification ku salaysan yahay ratio mugga ee wajiga saliidda iyo wajiga biyaha, viscosity ee labada weji iyo viscosity ee emulsion ka dhashay. , nooca iyo qadarka emulsifier-ga, Waxa kale oo jira heerkulka emulsification, laakiin wakhtiga emulsification waa in la sameeyo nidaamka si buuxda u emulsifier, kaas oo si dhow ula xiriira waxtarka ee qalabka emulsification. Waqtiga emulsification waxaa lagu go'aamin karaa iyadoo loo eegayo waayo-aragnimada iyo tijaabooyinka. Haddii homogenizer (3000 rpm) loo isticmaalo emulsification, waxay qaadataa 3-10 daqiiqo oo kaliya.
4. Xawaaraha kicinta Qalabka Emulsification wuxuu saameyn weyn ku leeyahay emulsification, mid ka mid ah taas oo ah saameynta xawaaraha kicinta ee emulsification. Xawaaraha kicinta ayaa dhexdhexaad ah si uu u sameeyo wajiga saliidda iyo wajiga biyaha si buuxda isku dhafan, iyo xawaaraha kicinta ayaa aad u sarreeya
5. Xawaaraha kicinta eeVakuum Mixer Homogenizer naqshadeynta ayaa saameyn weyn ku leh emulsification, mid ka mid ah taas oo ah saameynta xawaaraha kicinta ee emulsification. Xawaaraha kicinta dhexdhexaadka ah waa in la sameeyo wejiga saliidda iyo wejiga biyaha si buuxda isku dhafan. Haddii xawaaraha kicinta uu aad u hooseeyo, ujeedada isku darka buuxa si cad lama gaari doono. Si kastaba ha noqotee, haddii xawaaraha kicinta uu aad u sarreeyo, xumbo hawada ayaa la soo gelin doonaa nidaamka, taasoo ka dhigaysa nidaam saddex-waji ah. Waxay ka dhigtaa emulsions mid aan degganayn. Sidaa darteed, gelitaanka hawada waa in laga fogaadaa inta lagu jiro walaaqaya, iyo emulsifier vacuum wuxuu leeyahay waxqabad aad u fiican.
