Emulsifying kayan aiki
Babban kayan aikin injiniya don shirya emulsion shine injin emulsifying, wanda shine nau'in kayan aikin emulsifying don haɗa mai da ruwa daidai. A halin yanzu, akwai nau'ikan nau'ikan nau'ikan emulsifying na'ura: emulsifying mixer, colloid Mill da homogenizer. Emulsifying inji nau'in da tsarin, yi da kuma girman da emulsion barbashi (watsawa) da ingancin emulsion (kwanciyar hankali) yana da dangantaka mai kyau. Kullum, kamar yanzu yadu amfani da kayan shafawa factory stirring emulsifier, da emulsion samar da matalauta watsawa. Barbashi suna da girma kuma maras kyau, tare da rashin kwanciyar hankali da ƙazanta mai sauƙi. Amma ƙirar sa yana da sauƙi, farashin yana da arha, idan dai kuna kula da tsarin injin ɗin da ya dace, yi amfani da shi yadda ya kamata, amma kuma yana iya samar da buƙatun ingancin samfuran samfuran shahararrun kayan kwalliya. Colloid niƙa da homogenizer ne mafi kyau emulsifying kayan aiki. A cikin 'yan shekarun nan, kayan aikin emulsifying sun sami babban ci gaba, irin su injin emulsifying, da emulsion da aka shirya ta hanyar watsawa da kwanciyar hankali.
Yanayin zafi
Yawan zafin jiki na emulsification yana da tasiri mai girma akan emulsification, amma babu iyaka mai iyaka akan zafin jiki. Idan mai da ruwa ruwa ne, ana iya kwaikwaya su ta hanyar motsawa a zafin jiki. Gabaɗaya, yawan zafin jiki na emulsification ya dogara da yanayin narkewar abubuwa tare da babban ma'aunin narkewa a cikin matakai biyu, kuma yakamata a yi la'akari da abubuwan kamar nau'in emulsifier da solubility na lokacin mai da lokacin ruwa. Bugu da kari, ya kamata a kiyaye yawan zafin jiki na bangarorin biyu kusan iri daya, musamman ga kayan aikin kakin zuma da kitse tare da babban ma'aunin narkewa (sama da 70 ℃), lokacin da ake yin emulsifying, ba za a kara lokacin ruwan zafi ba, domin hana kakin zuma da mai daga crystallizing fita kafin emulsification, sakamakon a m ko m da m emulsion. Kullum magana, a lokacin da emulsifying, da yawan zafin jiki na mai da ruwa za a iya sarrafawa tsakanin 75 ℃ da 85 ℃. Idan lokacin mai yana da kakin zuma mai narkewa da sauran abubuwan da aka gyara, zafin emulsifying zai kasance mafi girma a wannan lokacin. Bugu da ƙari, idan danko ya karu sosai a cikin tsarin emulsification, abin da ake kira lokacin farin ciki kuma yana rinjayar haɗuwa, wasu zafin jiki na emulsification za a iya tashe su daidai. Idan emulsifier da aka yi amfani da shi yana da ƙayyadaddun zazzabi na canjin lokaci, ana kuma zaɓi mafi kyawun zafin jiki a kusa da yanayin canjin lokaci. Emulsification zafin jiki wani lokacin kuma rinjayar barbashi girman da emulsion. Idan anionic emulsifier na fatty acid sabulu ne kullum amfani, da barbashi girman emulsion ne game da 1.8-2.0μm lokacin da emulsification zafin jiki ne sarrafawa a 80 ℃. Idan barbashi size ne game da 6μm lokacin da emulsification ne da za'ayi a 60 ℃. Tasirin zafin jiki na emulsification akan girman barbashi yana da rauni lokacin da ba a yi amfani da emulsifier ba na ionic don emulsification.
Emulsifying lokaci
Emulsification lokaci a fili suna da tasiri a kan ingancin emulsion, da ƙaddarar lokaci na emulsifying shine bisa ga girman rabo na lokaci na ruwa lokaci, danko lokaci biyu da kuma haifar da danko na emulsion, nau'in da sashi na emulsifier, emulsifying. zafin jiki, emulsifying lokacin nawa, ya isa ya yi tsarin tsarin emulsification, yana da alaƙa da ingantaccen kayan aikin emulsification, lokacin emulsification. za a iya ƙaddara bisa ga kwarewa da gwaji. Emulsification tare da homogenizer (3000 RPM) yana ɗaukar mintuna 3-10 kawai.
Saurin hadawa
Emulsification kayan aiki yana da babban tasiri a kan emulsification, daya daga cikinsu shi ne tasirin motsawar sauri akan emulsification. Moderate stirring gudun ne don sa man lokaci da ruwa lokaci cikakken gauraye, ma low stirring gudun, a fili ba zai iya cimma manufar cikakken hadawa, amma ma high stirring gudun, zai kawo kumfa a cikin tsarin, sabõda haka, ya zama uku- lokaci tsarin, da kuma sa emulsion m. Don haka, dole ne a nisantar da iska yayin haɗuwa, kuma injin emulsifying yana da kyakkyawan aiki.
