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: e waatea ana, e whai hua ana te utu me te ngawari ki te whakamahi.
Nga huakore: he ngawari te kino me te whakanui ake i te uara waikawa ki te kore e penapena pai.
II.Waipiro Wao Nui
Ko te waipiro waro teitei he rauropi raina me te kaha o te hydrophobicity me te ngoikore o te hydrophilicity, 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 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 whakapokapoka 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.GPE Antifoamer he hydrophilicity pai, kaha antifoaming kaha, engari ano he wairewa nui e meinga wa tiaki poto o 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 ki te stearate hydrophobic.Ko nga ngota ngota me tenei hanganga ka kohia ki te atanga hau-wai, no reira he kaha te mahi o te mata me te pai o te whakakore.
IV.Polyether Whakarereke Silicone
Ko te Polyether Modified Silicone Antifoamers he momo hou o nga kaikawe tino kaha.He pai te utu me nga painga o te whakamararatanga pai, te kaha o te aukati 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. Kopolymer 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 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
