Antifoamers ikoreshwa mukugabanya ubushyuhe bwamazi hejuru yamazi, igisubizo no guhagarikwa, gukumira ifuro, cyangwa kugabanya ifuro ryakozwe mugihe cyo gukora inganda.Antifoamers isanzwe niyi ikurikira:

I. Amavuta Kamere (ni ukuvuga Amavuta ya Soya, Amavuta y'ibigori, nibindi)

Ibyiza: birahari, bidahenze kandi byoroshye gukoresha;

Ibibi: biroroshye kwangirika no kongera agaciro ka aside niba itabitswe neza.

II.Inzoga nyinshi za Carbone

Inzoga nyinshi za karubone ni molekile y'umurongo ifite hydrophobique ikomeye na hydrophilique idakomeye, ikaba ari antifoamer nziza muri sisitemu y'amazi.Ingaruka ya antifoaming ya alcool ifitanye isano no gukemuka kwayo no gukwirakwira mu gukemura ifuro.Inzoga za C7 ~ C9 ni Antifoamers nziza.Inzoga nyinshi ya karubone ya C12 ~ C22 itegurwa hamwe na emulisiferi ikwiye ifite ubunini bwa 4 ~ 9μm, hamwe na 20 ~ 50% emulioni y'amazi, ni ukuvuga defoamer muri sisitemu y'amazi.Esters zimwe na zimwe zifite antifoaming muri fermentation ya penisiline, nka oleate ya fenylethanol na lauryl phenylacetate.

III.Kurwanya Antifoamers

1. GP Antifoamers

Byakozwe hiyongereyeho polymerisiyasi ya okiside ya propylene, cyangwa imvange ya okiside ya Ethylene na oxyde ya propylene, hamwe na glycerol nkintangiriro.Ifite hydrophilicite idahwitse hamwe nubushake buke muburyo bwo kubira ifuro, bityo rero birakwiye gukoreshwa mumazi yoroheje ya fermentation.Kubera ko ubushobozi bwayo bwo kurwanya antifoaming buruta ubwo gusebanya, birakwiye ko byongerwaho muburyo bwibanze kugirango bibuze inzira ifuro ya fermentation yose.

2. GPE Antifoamers

Okiside ya Ethylene yongewe kumpera yumunyururu wa polypropilene glycol ihuza GP Antifoamers kugirango ikore polyoxyethylene oxypropylene glycerol hamwe na hydrophilique.GPE Antifoamer ifite hydrophilicity nziza, ubushobozi bukomeye bwa antifoaming, ariko kandi ifite solubile nini itera igihe gito cyo kubungabunga ibikorwa bya antifoaming.Kubwibyo, bifite ingaruka nziza mumisemburo ya fermentation.

3. GPEs Antifoamers

Block copolymer ifite iminyururu ya hydrophobi kumpande zombi hamwe na hydrophilique iminyururu ikorwa mugushiraho iminyururu ya GPE Antifoamers hamwe na hydrophobique stearate.Molekile hamwe niyi miterere ikunda guhurira kuri gazi-isukuye, bityo ikagira ibikorwa byubuso bukomeye hamwe nubushobozi bukomeye bwo gusebanya.

IV.Polyether Yahinduwe Silicone

Polyether Yahinduwe na Silicone Antifoamers nubwoko bushya bwa defoamers nziza.Birahenze cyane hamwe nibyiza byo gutatanya neza, imbaraga zikomeye zo kubuza ifuro, gutuza, kutagira uburozi kandi ntacyo bitwaye, ihindagurika rito hamwe nubushobozi bukomeye bwa Antifoamers.Ukurikije uburyo butandukanye bwo guhuza imbere, burashobora kugabanywamo ibyiciro bibiri bikurikira:

1. Copolymer hamwe -Si-OC- inkwano yateguwe na aside nka catalizator.Iyi defoamer iroroshye hydrolysis kandi ifite umutekano muke.Niba buffer amine ihari, irashobora kugumana igihe kirekire.Ariko kubera igiciro cyayo gito, ubushobozi bwiterambere buragaragara cyane.

2. Kopolymer ihujwe na - si-c-bond ifite imiterere ihamye kandi irashobora kubikwa mumyaka irenga ibiri mugihe gifunze.Nyamara, kubera ikoreshwa rya platine ihenze nkumusemburo mugikorwa cyo kubyara, igiciro cyumusaruro wubwoko bwa antifoamers ni kinini, ntabwo rero cyakoreshejwe cyane.

V. Antifoamer ya Organic Silicon

Umutwe ukurikira.
