Abvantbuwan amfãni: Akwai, ingantaccen aiki da sauƙi.
Rashin daidaituwa: Yana da sauƙin lalacewa kuma yana ƙaruwa da darajar acid idan ba a adana shi da kyau ba.
II. Babban carbon giya
Babban carbon giya shine kwayoyin halitta tare da karfin ruwa da kuma rauni hydrophilicity, wanda shine ingantaccen antifoamer mai inganci a tsarin ruwa. Tasirin maganin maye na giya yana da alaƙa da karuwarsa da kuma yaduwa cikin bayani mai faɗi. Barasa na C7 ~ C9 shine mafi yawan maganin antifame. Babban carbon barasa na C12 ~ C22 an shirya tare da abubuwan da suka dace emulsifiers tare da girman barbashi mai girma na 4 ~ 50% emulsion da 20 ~ 50% ruwa emulsion da 20 ~ 50% ruwa emulsion. Wasu esters kuma suna da tasirin antifoing a cikin penifillin fermentation, kamar phenylethanol oleate da layl phendlanetate.
III. Polyether mai shayarwa
1. GP Anttifamers
Ma'anar polymerization na provyleme opylelene oxide, ko cakuda ethylene oxide da propylelene opthylene opide, tare da glycerl kamar wakili. Yana da talauci hydrophility da ƙarancin ƙila a matsakaici na kumfa, don haka ya dace a yi amfani da shi a cikin ruwa fermentation. Tunda iyawar ta antafazing ita ce ta fi na lalata, ya dace da a ƙara a cikin matsakaici mafi matsakaici don hana foaming tsari tsarin aiwatar da fermentation tsari.
2. GPE Antifame
An kara Ethylene Oxide a karshen Polypropylene glycol sarkar na GP na GP na antifamares don samar da glycolylene glertrol tare da ƙarshen hydrophilic. GPEFOMOAMER yana da hydrophility mai kyau, iko mai ƙarfi, amma kuma yana da babban soci wanda ke haifar da taƙaitaccen lokacin aikin antiftoaming. Saboda haka, yana da tasiri mai kyau a cikin viscous fermentation broth.
3. GPES VARIFOAMSERS
Tufafin copolymer tare da sarƙoƙi na ruwa a duka iyakar biyu ne ta hanyar sanya ƙarshen sarkar gpefoarkers tare da steamerate steamate. Kwayoyin halitta tare da wannan tsarin suna yin tattarawa a dandalin gidan mai, saboda haka suna da ƙarfi aiki da kuma ingantaccen aiki.
IV. Polyether gyara silicone
Polyether gyara silicone antifoame ne sabon nau'in metoamers mai inganci. Yana da tsada-tsada tare da fa'idodi na mai kyau watsawa, karfi da kumfa mai hana, kwanciyar hankali, wanda ba mai guba ba, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙananan marasa hankali, ƙarancin ɓarna da ƙarfin ƙira. A cewar daban-daban hanyoyin haɗin ciki na ciki, ana iya kasu kashi biyu cikin rukunan biyu:
1. Copolymer tare da -Si-OCOND ya shirya tare da acid a matsayin mai kara kuzari. Wannan Defoamer mai sauki ne ga hydrolysis kuma yana da ƙarancin kwanciyar hankali. Idan mai ɗaukar hoto yana nan, ana iya riƙe shi na tsawon lokaci. Amma saboda farashinsa ne, damar ci gaba a fili yake.
2. Cutar copolymer ya ɗaure ta - SI-C-Bond yana da ingantaccen tsari kuma ana iya adana shi fiye da shekaru biyu a ƙarƙashin yanayin rufewa. Koyaya, saboda amfani da platinum mai tsada a matsayin mai kara kuzari a cikin tsarin samarwa, samar da kudin irin wannan antifowers yana da yawa, saboda haka ba a amfani dashi.
