Ka whakamahia nga antifoamers ki te whakaiti i te mata o te wai, te otinga me te whakatārewatanga, te aukati i te hanga pahuka, te whakaiti ranei i te pahuka i te wa o te mahi ahumahi. Ko nga Antifoamers noa e whai ake nei:

I. Hinu Maori (ara te Hinu Soybean, Hinu Kanga, etc.)

Painga: te waatea, te utu-utu me te ngawari te whakamahi;

Nga ngoikoretanga: he ngawari te kino me te whakanui ake i te uara waikawa mena kaore e penapena pai.

II.Waipiro Wao Nui

Ko te waipiro waro teitei he rauropi raina me te hydrophobicity kaha me te hydrophilicity ngoikore, he antifoamer whai hua i roto i te punaha wai. E pa ana te awenga antifoaming o te waipiro ki tona memehatanga me te whakamaarama i roto i te wairewa pahuka. Waipiro o C7 ~ C9 Ko te tino whai hua Antifoamers. Ko te waipiro waro teitei o te C12 ~ C22 kua rite ki nga emulsifiers e tika ana me te rahi o te matūriki o te 4 ~ 9μm, me te 20 ~ 50% te whakaehunga wai, ara, te defoamer i roto i te punaha wai. Ko etahi o nga hākawa ka whai hua whakaahuru i roto i te fermentation penicillin, penei i te phenylethanol oleate me te lauryl phenylacetate.

III.Polyether Antifoamers

1. GP Antifoamers

He mea hanga ma te taapiri polymerization o te propylene oxide, te ranunga ranei o te ethylene oxide me te propylene oxide, me te glycerol hei kaihoko tiimata. He ngoikore te hydrophilicity me te iti o te wairewa i roto i te reo pahuka, no reira he pai ki te whakamahi i roto i te wai FERMENTATION angiangi. I te mea he pai ake tona kaha ki te whakangao, he pai ki te whakauru atu ki roto i te reo basal ki te aukati i te mahi pahuka o te tukanga FERMENTATION katoa.

2. GPE Antifoamers

Ka taapirihia te Ethylene oxide ki te pito o te hononga mekameka polypropylene glycol o GP Antifoamers hei hanga polyoxyethylene oxypropylene glycerol me te mutunga hydrophilic. He pai te hydrophilicity o te GPE Antifoamer, he kaha te kaha ki te aukati, engari he nui ano te whakarewatanga e pa ana ki te wa poto o te mahi antifoaming. Na reira, he painga pai i roto i te hupa FERmentation viscous.

3. GPEs Antifoamers

Ka hangaia he copolymer poraka me nga mekameka hydrophobic i nga pito e rua me nga mekameka hydrophilic ma te hiri i te pito mekameka o GPE Antifoamers me te stearate hydrophobic. Ko nga ngota ngota me tenei hanganga ka kohia ki te atanga hau-wai, no reira he kaha te mahi mata me te pai o te whakakore.

IV.Polyether Whakarerekē Silicone

Ko te Polyether Modified Silicone Antifoamers he momo hou o nga kaikawe tino kaha. He pai te utu me nga painga o te marara pai, te kaha ki te aukati i te pahuka i te kaha, te pumau, te kore-paitini me te kino, te iti o te ngoikore me te kaha o te kaha Antifoamers. E ai ki nga momo hononga honohono o roto, ka taea te wehewehe ki nga waahanga e rua e whai ake nei:

1. He kapolymer me te here -Si-OC- kua whakaritea me te waikawa hei whakakorikori. He ngawari te whakamaaramatanga o tenei kai whakapoipoka, he ngoikore te pumau. Mena kei reira he amine buffer, ka taea te pupuri mo te wa roa. Engari na te iti o te utu, ka tino kitea te kaha o te whanaketanga.

2. Ko te copolymer e herea ana e – si-c-bond he ahua pumau tonu, ka taea te penapena mo te neke atu i te rua tau i raro i nga tikanga kati. Heoi, na te whakamahinga o te konukawata utu nui hei whakakorikori i roto i te mahi whakaputa, he nui te utu o tenei momo antifoamers, na reira kaore i whakamahia nuitia.

V. Organic Silicon Antifoamer
