1 Ukunganyibiliki okanye ukunyibilika kakubi kulwelo olukhupha igwebu kuthetha ukuba igwebu liphukile, kwayeisixhobo sokususa ifoamkufuneka igxininiswe kwaye igxile kwifilimu yefoam. Kwi-defoamer, kufuneka igxininiswe kwaye igxile ngoko nangoko, kwaye kwi-defoamer, kufuneka ihlale ikwimeko enjalo.
Ngoko ke, i-defoamer ikwimeko yokugcwala kakhulu kulwelo olunegwebu, kwaye kulula ukufikelela kwimeko yokugcwala kakhulu kuphela ukuba ayinyibiliki okanye ayinyibiliki kakuhle. Ayinyibiliki okanye ayinyibiliki kakuhle, kulula ukuyiqokelela kwindawo yokudibana kwegesi nolwelo, kulula ukuyigxila kwifilimu yegwebu, kwaye inokudlala indima kuxinzelelo oluphantsi. Kwi-defoamers ezisetyenziswa kwiinkqubo zamanzi, iimolekyuli zezithako ezisebenzayo kufuneka zingabi namanzi kakhulu kwaye zinganyibiliki kangako, kwaye ixabiso le-HLB kufuneka libe phakathi kwe-1.5-3 ukuze isebenze kakuhle.
2 Uxinzelelo lomphezulu luphantsi kunolo lolwelo olukhupha igwebu. Kuphela xa amandla aphakathi kweemolekyuli ze-defoamer emancinci kwaye uxinzelelo lomphezulu luphantsi kunolo lolwelo olukhupha igwebu, apho amasuntswana e-defoamer anokuntywiliselwa aze anwetshwe kwifilimu yegwebu. Kubalulekile ukuqaphela ukuba uxinzelelo lomphezulu lolwelo olukhupha igwebu alukho uxinzelelo lomphezulu lwesisombululo, kodwa luxinzelelo lomphezulu lwesisombululo esikhupha igwebu.
3. Umlinganiselo othile wobudlelwane nolwelo olukhupha igwebu. Ekubeni inkqubo yokususa igwebu ngokwenene ilukhuphiswano phakathi kwesantya sokuwa kwegwebu kunye nesantya sokuveliswa kwegwebu, i-defoamer kufuneka ikwazi ukusasazeka ngokukhawuleza kulwelo olukhupha igwebu ukuze ikwazi ukudlala indima ngokukhawuleza kuluhlu olubanzi lolwelo olukhupha igwebu. Ukuze i-defoamer isasazeke ngokukhawuleza, izithako ezisebenzayo ze-defoamer kufuneka zibe nomlinganiselo othile wobudlelwane nolwelo olukhupha igwebu. Ukuba izithako ezisebenzayo ze-defoamer zisondele kakhulu kulwelo olukhupha igwebu, ziya kunyibilika; ukuba zikude kakhulu, kuya kuba nzima ukuzisasaza. Kuphela xa ubudlelwane bufanelekile, isiphumo siya kuba sihle.
4. Akukho mpendulo yamakhemikhali kulwelo olukhupha igwebu. I-defoamer iphendula kulwelo olukhupha igwebu. Kwelinye icala, i-defoamer iya kulahlekelwa yimpembelelo yayo, kwaye kwelinye icala, izinto eziyingozi zinokuveliswa, ezichaphazela ukukhula kweentsholongwane.
5. Ukuguquguquka okuphantsi kunye nexesha elide lokusebenza. Okokuqala, misela inkqubo ekufuneka isetyenziswe kuyo i-defoamer, nokuba yinkqubo esekwe emanzini okanye inkqubo esekwe kwi-oyile. Umzekelo, kwishishini lokubilisa, ii-defoamer ezisekwe kwi-oyile ezifanaKufuneka kusetyenziswe i-silicone okanye i-polyether eguqulwe yi-polyether. Ishishini lokugquma elisekwe emanzini kufuneka lisebenzise ii-defoamers ezisekwe emanzini kunye nee-defoamers ze-silicone. Khetha i-defoamer, thelekisa isixa esongeziweyo, kwaye ubhekisele kwixabiso ukuze ufumane imveliso ye-defoamer efanelekileyo nengabizi kakhulu.
