Ka'idar defoamer
Wakilin defoaming, wanda kuma aka sani da wakilin defoaming, yana da ka'idoji masu zuwa:
1. An rage tashin hankali na gida na kumfa, wanda ya haifar da fashewar kumfa
Tsarin yana farawa lokacin da aka yi amfani da barasa mafi girma ko man kayan lambu a kan kumfa, wanda, lokacin da aka narkar da shi a cikin kumfa, yana rage yawan tashin hankali a can.Saboda waɗannan abubuwa gabaɗaya ba su da narkewa ga ruwa, raguwar tashin hankalin saman yana iyakance ga yanki na gida na kumfa, yayin da tashin hankalin saman kumfa ke canzawa.Bangaren raguwar tashin hankali na saman yana da ƙarfi sosai a duk kwatance, tsawaitawa, kuma a ƙarshe ya fashe.
2, lalata elasticity na fim kuma haifar da fashewar kumfa
Lokacin da aka ƙara wakilin defoaming zuwa tsarin kumfa, zai yada zuwa ga mai amfani da gas-ruwa, yana da wuya ga surfactant tare da aikin kwantar da kumfa don dawo da elasticity na fim din.
3, inganta ruwa film magudanun ruwa
Wakilin defoaming zai iya inganta magudanar ruwa na fim ɗin ruwa, wanda ke haifar da fashewar kumfa, ƙimar kumfa na kumfa zai iya yin la'akari da kwanciyar hankali na kumfa, ƙara wani abu don hanzarta zubar da kumfa, kuma zai iya taka rawar lalata.
4, ƙara hydrophobic m barbashi iya haifar da kumfa fashe
Hydrophobic m barbashi a kan surface na kumfa zai jawo hankalin da hydrophobic karshen surfactants, sabõda haka, hydrophobic barbashi samar da hydrophilicity da kuma shiga cikin ruwa lokaci, don haka kamar yadda a yi wasa da rawar defoaming.
5, solubilizing kumfa surfactant zai iya haifar da kumfa fashe
Wasu ƙananan ƙwayoyin ƙwayoyin cuta waɗanda ke haɗuwa da kyau tare da bayani na iya narkar da surfactant bubbling kuma su rage tasiri mai tasiri.Low kwayoyin abubuwa tare da wannan sakamako, kamar octanol, ethanol, propanol da sauran alcohols, ba zai iya kawai rage surfactant maida hankali a kan surface Layer, amma kuma narke a cikin surfactant adsorption Layer, rage tightness tsakanin surfactant kwayoyin, don haka raunana kwanciyar hankali na kumfa.
6. Electrolyte ya narke biyu Layer na surfactant
Domin surfactant tare da taimakon kumfa biyu lantarki Layer hulda, da kwanciyar hankali na kumfa ruwa, ƙara talakawa electrolyte iya rushe surfactant biyu lantarki Layer don taka rawa a defoaming.
