：

洗手液是指以去除手上污漬、細(xì)菌為目的而設(shè)計的清潔產(chǎn)品，由必需的活性成分和輔助成分構(gòu)成，作為活性成分的是表面活性劑；除了表面活性劑起到清潔的作用外，還需要加入防腐劑、保濕劑、pH調(diào)節(jié)劑、香精、色素、增稠劑等來滿足消費者關(guān)于洗手液的各種效能

ProductionProcess

Productionprocessofliquiddetergent1-feeding;2-tank;3,6-measuringtank;4-emulsifyingtank;5-homogenizer;7-coolingtank;8-finishedproducttank洗手液的生產(chǎn)工藝比較簡單，一般均采用間歇式批量化生產(chǎn)工藝，而不采用連續(xù)化生產(chǎn)方式，主要是因為洗手液的品種繁多，根據(jù)市場要求須不斷變換原材料和工藝條件等。洗手液的主要工序有：原料的精致處理、混配、均質(zhì)化、排氣、老化、成品包裝等。這些化工單元操作設(shè)備主要是帶攪拌的攪拌罐、高效乳化或者均質(zhì)設(shè)備，各種過濾器、物料輸送泵、計算泵和真空泵，以及計量罐和灌裝設(shè)備等。

Theproductionprocessofhandsanitizerisrelativelysimple.Generally,batch-typebatchproductionprocessisadoptedinsteadofcontinuousproductionmode,mainlybecauseofthewidevarietyofhandsanitizers,andtherawmaterialsandprocessconditionsmustbeconstantlychangedaccordingtomarketrequirements.Themainprocessesofhandsanitizerare:pretreatmentofrawmaterials,compounding,homogenization,exhaust,aging,finishedpackaging.Thesechemicalunitoperatingequipmentaremainlystirredtanks,high-efficiencyemulsificationorhomogenizationequipment,variousfilters,materialtransferpumps,calculationpumpsandvacuumpumps,aswellasmeteringtanksandfillingequipment.
