Ubwoko bwa Antifoamers I.

Antifoamers ikoreshwa mukugabanya ubukana bwamazi, gukemura 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, bikoresha neza kandi byoroshye gukoresha.
Ibibi: biroroshye kwangirika no kongera aside aside niba itabitswe neza.

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

III.Kurwanya Antifoamers
1. GP Antifoamers
Byakozwe hiyongereyeho polymerisation ya okiside ya propylene, cyangwa imvange ya okiside ya Ethylene na okiside ya propylene, hamwe na glycerol nkibikoresho byo gutangiza.Ifite hydrophilicite idahwitse hamwe nubushyuhe buke muburyo bwo kubira ifuro, birakwiriye rero gukoreshwa mumazi yoroheje.Kubera ko ubushobozi bwayo bwo kurwanya antifoaming buruta ubwo gusebanya, birakwiriye ko byongerwaho muburyo bwibanze kugirango bibuze uburyo bwo kubira ifuro 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 hydrophobique kumpande zombi hamwe na hydrophilique iminyururu ikorwa mugushiraho iminyururu ya GPE Antifoamers hamwe na hydrophobique stearate.Molekile hamwe niyi miterere ikunda gukusanyiriza kuri gazi-yamazi, bityo ikagira ibikorwa byubuso bukomeye hamwe nubushobozi bukomeye bwo gusebanya.
