Ka whakamahia nga antifoamers hei whakaiti i te uaua o te mata o te wai, te otinga me te aukati, te aukati i te waihanga i te paoa, te whakaiti ranei i te pahuka i hangaia i te wa o te hanga ahumahi. Ko nga mea antifoamers noa e whai ake nei:
I. Te hinu taiao (ara, hinu soybean, hinu witi, etc.)
Painga: E waatea ana, utu utu-utu me te ngawari.
Ngo ngoikoretanga: He ngawari ki te aukati me te whakapiki i te uara waikawa ki te kore e rongoa pai.
II. Te waipiro waro nui
Ko te miihini waro nui he ngota te raina me te hauhautanga kaha me te ngoikore ngoikore o te hydrophility, he mea whai hua i roto i te punaha wai. Ko te hua antifoaming o te waipiro e pa ana ki tona whakaraeraetanga me te wehewehe i te otinga whakatipu. Ko te waipiro o te C7 ~ C9 nga mea tino whai hua. Ko te waipiro nui o te waipiro c12 ~ c22 kua rite ki te rahi o te 4 ~ 9μm, me te 20 ~ 50%, ko te punaha wai. Ko etahi o nga kaiwhaiwhai he paanga antifoamiming i te penicillin fermertation, penei i te Phenylethanol Oleate me Lauryl Phenylacetate.
III. Polyether antifoamers
1. GP Antifoamers
I hangaia ma te taha o te polymerization oxide oxide, he ranunga ranei o te oxide o te ethyyne me te miiharo propylene, me te glycerol rite te kaihoko timatanga. He ngoikore o te hydrophilicity me te whakaheke iti i roto i te whakatipu reo, na reira e tika ana kia whakamahia i roto i te wai angiangi. Mai i te mea ko tana kaha antifoaming he mea nui ki te aukati, he pai ki te taapiri i te waa basal hei aukati i te tukanga whakakakahu i nga tikanga katoa o te waahanga.
2. GPE Antifoamers
Ko te oxide Oxide te taapiri i te mutunga o te Polypropylene Glycol Chain o te GP Antifoamers ki te hanga polyoxyethylene oxypropy me te mutunga hydrophilic. He pai te hydrophility, he kaha te kaha antifoamingaing, engari he nui ano te tohatoha i te waa tiaki poto mo te mahi antifoaming. Na reira, he pai te painga o te hupa rumaki.
3. Gpes Antifoamers
He poraka poraka me nga mekameka hydrophobic i nga wa e rua me nga wai hydrophilililic ka hangaia ma te hiri i te mutunga o te mekameka o te gpe Ko nga ngota me tenei hanganga e pa ana ki te kohikohi i te atanga hau-wai, na reira he kaha te kaha o te taiao me te tino ngoikore.
Iv. Polyether i whakarerekehia
Ko te polyether i whakarereke i te antifoamers silicomer ko te momo hou o nga kaiwhakaari nui. He utu - he whai hua ki te painga o te marara pai, te kaha aukati kaha, te kaha-kore-paitini me te kino, te ngoikore me te kaha antifoamers kaha. E ai ki nga momo hononga honohono o roto, ka taea te wehe ki nga waahanga e rua e whai ake nei:
1 He ngawari tenei ki te hydrolysis me te kore e mau. Mena kei te noho mai te kaikorero a Amine, ka taea te pupuri mo te wa roa ake. Engari na te mea he iti te utu, ko te whanaketanga o te whanaketanga ka tino kitea.
2 Heoi, i te whakamahi i te konukawata utu nui i roto i te tukanga whakaputa, he nui te utu o tenei momo antifoamers, na reira kaore i whakamahia whānuitia.
V. Organic Antifomer
... Tuhinga o mua.
