Ana amfani da magungunan hana kumfa don rage matsin lamba a saman ruwa, maganin da kuma dakatarwa, hana samuwar kumfa, ko rage kumfa da ake samu yayin samar da masana'antu. Magungunan hana kumfa da aka fi amfani da su sune kamar haka:

I. Man fetur na halitta (misali Man waken soya, Man masara, da sauransu)

Amfani: akwai, mai araha kuma mai sauƙin amfani;

Rashin amfani: yana da sauƙin lalacewa da ƙara darajar acid idan ba a adana shi da kyau ba.

II.Babban Barasa Mai Haɗarin Carbon

Babban barasa mai yawan carbon wani nau'in kwayar halitta ce mai layi wadda ke da ƙarfin hydrophobicity da kuma rauni a hydrophilicity, wanda shine ingantaccen maganin kumfa a cikin tsarin ruwa. Tasirin hana kumfa na barasa yana da alaƙa da narkewarsa da yaɗuwa a cikin maganin kumfa. Barasa na C7 ~ C9 shine mafi inganci Antifoamers. An shirya Babban barasa mai yawan carbon na C12 ~ C22 tare da emulsifiers masu dacewa tare da girman barbashi na 4 ~ 9μm, tare da 20 ~ 50% na emulsion na ruwa, wato, defoamer a cikin tsarin ruwa. Wasu esters kuma suna da tasirin hana kumfa a cikin fermentation na penicillin, kamar phenylethanol oleate da lauryl phenylacetate.

III.Polyeter Antifoamers

1. Magungunan hana kumfa na GP

An yi shi ta hanyar ƙara polymerization na propylene oxide, ko cakuda ethylene oxide da propylene oxide, tare da glycerol a matsayin abin da zai fara aiki. Yana da ƙarancin hydrophilicity da ƙarancin narkewa a cikin kumfa, don haka ya dace a yi amfani da shi a cikin ruwa mai laushi. Tunda ikon hana kumfa ya fi na defoaming, ya dace a ƙara shi a cikin basal medium don hana tsarin kumfa na dukkan tsarin fermentation.

2. Maganin Kumfa na GPE

Ana ƙara sinadarin Ethylene oxide a ƙarshen polypropylene glycol chain link na GP Antifoamers don samar da polyoxyethylene oxypropylene glycerol mai ƙarshen hydrophilic. GPE Antifoamer yana da kyakkyawan hydrophilicity, ƙarfin hana kumfa mai ƙarfi, amma kuma yana da babban narkewa wanda ke haifar da ɗan gajeren lokacin gyara ayyukan hana kumfa. Saboda haka, yana da kyakkyawan tasiri a cikin ruwan fermentation mai ƙauri.

3. GPEs Masu hana kumfa

Ana samar da wani bututun copolymer mai sarƙoƙin hydrophobic a ƙarshen biyu da sarƙoƙin hydrophilic ta hanyar rufe ƙarshen sarƙoƙin GPE Antifoamers da hydrophobic stearate. Kwayoyin da ke da wannan tsari suna taruwa a mahaɗin gas-liquid, don haka suna da ƙarfin aiki a saman da kuma ingantaccen aiki na defoaming.

IV.Silicone da aka Gyara da Polyeter

Polyether Modified Silicone Antifoamers wani sabon nau'in na'urorin rage kumfa ne mai inganci. Yana da inganci mai kyau tare da fa'idodin watsawa mai kyau, ƙarfin hana kumfa mai ƙarfi, kwanciyar hankali, ba shi da guba kuma ba shi da lahani, ƙarancin canjin yanayi da ƙarfin Antifoamers mai ƙarfi. Dangane da nau'ikan haɗin kai na ciki daban-daban, ana iya raba shi zuwa rukuni biyu masu zuwa:

1. Copolymer mai -Si-OC- bond wanda aka shirya tare da acid a matsayin mai kara kuzari. Wannan defoamer yana da sauƙin hydrolysis kuma yana da rashin kwanciyar hankali. Idan akwai amine buffer, ana iya riƙe shi na dogon lokaci. Amma saboda ƙarancin farashi, yuwuwar haɓakawa a bayyane take.

2. Copolymer ɗin da aka haɗa ta – si-c-bond yana da tsari mai kyau kuma ana iya adana shi fiye da shekaru biyu a ƙarƙashin yanayi mai rufewa. Duk da haka, saboda amfani da platinum mai tsada a matsayin mai haɓaka aiki a cikin tsarin samarwa, farashin samar da wannan nau'in maganin hana kumfa yana da yawa, don haka ba a yi amfani da shi sosai ba.
