It seems important to study the life cycle of the foam, its aging process, in connection with the fact that viscosity and foam stability is in direct function of the structure and size of foam cells, which, among other things, changes in time. Try to identify the causes, related to surface-active properties of substances, influencing the trends described above. It is obvious that the viscosity of foam in this case will necessarily change. Through our own research to determine the viscosity of freshly prepared foams and foams that are subject to aging. Foams were investigated on the basis of ammonium and sodium salts of fatty sulphonaphthenic with added saponin and gelatin. |

Se va încerca identificarea cauzelor, legate de proprietăţile tensioactive ale substanţelor, ce influenţează asupra tendinţelor descrise mai sus. Este evident, că în acest caz viscozitatea spumei se va modifica în mod obligatoriu. Prin cercetări proprii s-a determinat viscozitatea spumelor proaspăt preparate si a spumelor, ce sunt supuse unui proces de îmbătrânire. Au fost cercetate spumele pe baza de săruri de amoniu şi natriu de acizi sulfonaftenici cu adaosuri de saponina şi gelatină</p></cfAbstr> <cfAbstr cfLangCode='RU' cfTrans='o'><p>Представляется важным изучение жизненного цикла пен, процессов её старения в связи с тем, что вязкость и стойкость пен находятся в прямой зависимости от структуры, а также и от размеров ячеек пены, которые помимо всего прочего ещё и видоизменяются со временем. Попытаемся выявить причины, связанные со свойствами поверхностноактивных веществ оказывающих влияние на вышеприведенную тенденцию. Очевидно, что в такой ситуации вынуждена изменяться вязкость пен. Нашими исследованиями была определена вязкость свежеприготовленных пен, а также пен, подвергающихся процессам старения. Исследовались пены на основе аммонийных и натровых солей сульфонафтеновых кислот с добавками сапонина и желатины.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-81750</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-39330</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-865</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> </cfPers_ResPubl> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-81750</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-81750-1</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> <cfFamilyNames>Колесниченко</cfFamilyNames> <cfFirstNames>М.</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-39330</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-39330-1</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> <cfFamilyNames>Куликов</cfFamilyNames> <cfFirstNames>В.</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-865</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-865-1</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012-04-01T24:00:00</cfStartDate> <cfFamilyNames>Лупушор</cfFamilyNames> <cfFirstNames>Н.</cfFirstNames> </cfPersName_Pers> </cfPers> </CERIF>
