Ka whakamahia ngā ārai-huka hei whakaiti i te kukū o te mata o te wai, te wairewa me te whakatārewatanga, hei ārai i te hanganga o te pahuka, hei whakaiti rānei i te pahuka e puta ana i te wā o te hanga ahumahi. Ko ngā ārai-huka e whakamahia whānuitia ana koia ēnei:

I. Hinu Taiao (arā, Hinu Pīni Soya, Hinu Kānga, me ētahi atu)

Ngā Painga: e wātea ana, e iti ana te utu, e ngāwari ana hoki te whakamahi;

Ngā huakore: he ngāwari te pirau, ā, ka piki ake te uara waikawa mēnā kāore i te rongoa pai.

Tuarua.Waipiro Waro Teitei

He ngota raina te waipiro waro-nui, he kaha te wai-whakaaro, he ngoikore te wai-whakaaro, he mea whai hua hei ārai i te pahuka i roto i te pūnaha wai. Ko te pānga ārai-huka o te waipiro e pā ana ki tōna wairewatanga me tōna horapa i roto i te otinga pahuka. Ko te waipiro o C7 ~ C9 te mea tino whai hua hei ārai i te pahuka. Ka whakaritea te waipiro waro-nui o C12 ~ C22 me ngā emulsifiers tika me te rahi matūriki o te 4 ~ 9μm, me te 20 ~ 50% emulsion wai, arā, te dehuka i roto i te pūnaha wai. He pānga ārai-huka anō hoki tō ētahi esters i roto i te fermentation penicillin, pērā i te phenylethanol oleate me te lauryl phenylacetate.

III.Ngā Ārai Huka Polyether

1. Ngā Kaiwhakakore Huka GP

I hangaia mā te tāpiri i te polymerization o te propylene oxide, i te ranunga rānei o te ethylene oxide me te propylene oxide, me te glycerol hei tīmatanga. He iti te hydrophilicity, ā, he iti te wairewa i roto i te reo pahuka, nō reira he pai mō te whakamahi i roto i te wai whakapūkara angiangi. Nā te mea he pai ake tōna kaha ki te ārai i te pahuka i tērā o te tango pahuka, he pai mō te tāpiri ki te reo taketake hei aukati i te tukanga pahuka o te tukanga whakapūkara katoa.

2. Ngā Ārai Huka GPE

Ka tāpirihia te waikura ethylene ki te pito o te mekameka polypropylene glycol o ngā GP Antifoamers hei hanga i te polyoxyethylene oxypropylene glycerol me te pito hydrophilic. He pai te hydrophilic o te GPE Antifoamer, he kaha ki te ārai i te pahuka, engari he nui hoki te wairewa e hua ai te wā tiaki poto o te mahi ārai i te pahuka. Nō reira, he pai te pānga ki te hupa whakapūkara matotoru.

3. Ngā Ārai Huka GPE

Mā te hiri i te pito mekameka o ngā GPE Antifoamers ki te stearate hydrophobic, ka hangaia he poraka copolymer me ngā mekameka hydrophobic i ngā pito e rua, ā, ka hangaia he mekameka hydrophilic mā te hiri i te pito mekameka o ngā GPE Antifoamers ki te hydrophobic stearate. Ko ngā ngota ngota me tēnei hanganga ka kohikohi i te atanga hau-wai, nō reira he kaha te mahi mata me te pai o te tango huka.

IV.Silicone Kua Whakarerekētia te Polyether

He momo hou ngā Antifoamers Silicone Modified Polyether o ngā defoamers tino whai hua. He iti te utu, ā, he pai te horapa, he kaha te aukati i te pahuka, he pumau, kāore he paitini, he kino hoki, he iti te hurihuri, ā, he kaha te Antifoamers. E ai ki ngā momo hononga ā-roto rerekē, ka taea te wehewehe ki ngā wāhanga e rua e whai ake nei:

1. He Copolymer me te hononga -Si-OC- i hangaia ki te waikawa hei whakakorikori. He ngāwari te waikura i tēnei mea whakakore huka, ā, he ngoikore te pumau. Mena he amine buffer kei reira, ka taea te pupuri mō te wā roa. Engari nā te iti o te utu, he tino kitea te pūmanawa whanaketanga.

2. He hanganga pumau te hononga-kopaira e herea ana e te hononga-si-c, ā, ka taea te penapena mō te neke atu i te rua tau i raro i ngā āhuatanga kati. Heoi, nā te whakamahinga o te konukawata utu nui hei whakakorikori i roto i te tukanga whakaputa, he nui te utu whakaputa o tēnei momo ārai-huka, nō reira kāore i te whānui te whakamahinga.
