1 ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai hoʻohāhā ʻo ia hoʻi, ua haki ka huʻa, a ʻo kadefoamerpono e hoʻopaʻa ʻia a kau ʻia ma luna o ke kiʻi ʻoniʻoni. No ka mea hoʻoheheʻe, pono e hoʻopaʻa ʻia a hoʻopaʻa koke ʻia, a no ka defoamer, pono e mālama mau ʻia i kēia kūlana.
No laila, aia ka defoamer i kahi kūlana supersaturated i loko o ka wai huʻa, a maʻalahi ke hiki i kahi kūlana supersaturated inā ʻaʻole hiki ke hoʻoheheʻe a maikaʻi ʻole. ʻAʻole hiki ke hoʻoheheʻe ʻia a maikaʻi ʻole paha, maʻalahi e hōʻiliʻili ma ke kinoea-wai, maʻalahi e nānā i ke kiʻi ʻoniʻoni, a hiki ke pāʻani i kahi hana ma kahi haʻahaʻa haʻahaʻa. No nā defoamers i hoʻohana ʻia i loko o nā ʻōnaehana wai, pono ka hydrophobic ikaika a me ka hydrophilic nāwaliwali nā molekala o nā mea hana, a ʻo ka waiwai HLB ma waena o 1.5-3 e hana maikaʻi loa.
2 ʻOi aku ka haʻahaʻa haʻahaʻa o ka ʻili ma mua o ka wai huʻa. Aia wale nō ka liʻiliʻi o ka ikaika intermolecular o ka defoamer a ʻoi aku ka haʻahaʻa o ka ʻili o ka ʻili ma mua o ka wai huʻa, hiki ke hoʻoheheʻe ʻia nā ʻāpana defoamer a hoʻonui ʻia ma ke kiʻi ʻoniʻoni. Pono e hoʻomaopopo ʻia ʻaʻole ʻo ka ʻili o ka ʻili o ka wai hoʻoheheʻe ʻana i ka ʻili o ka hopena, akā ʻo ka ʻili o ka ʻili o ka hāhā.
3. Kekahi degere o ka pili me ka wai hū. No ka mea, ʻo ke kaʻina hana defoaming he hoʻokūkū maoli nō ia ma waena o ka wikiwiki o ka hāʻule ʻana o ka huʻihuʻi a me ka wikiwiki o ka hana ʻana o ka ʻūhā, pono e hiki i ka defoamer ke hoʻopuehu koke i ka wai huʻa i hiki iā ia ke pāʻani wikiwiki i kahi ʻano ākea o ka wai huʻa. I mea e hoʻopuehu wikiwiki ai ka defoamer, pono e loaʻa i nā mea hana o ka defoamer kahi pae o ka pilina me ka wai huʻa. Inā kokoke loa nā mea hana o ka defoamer i ka wai huʻa, e hoʻoheheʻe lākou; inā lōʻihi loa lākou, paʻakikī ke hoʻopuehu. Ke kūpono wale ka pilina, e maikaʻi ka hopena.
4. ʻAʻohe hopena kemika me ka wai huʻa. Hoʻopili ka defoamer me ka wai huʻa. Ma kekahiʻaoʻao, e nalowale ka hopena o ka defoamer, a ma kekahiʻaoʻao, hiki ke hanaʻia nā meaʻino, e pili ana i ka uluʻana o nā microorganisms.
5. Haʻahaʻa volatility a lōʻihi hana manawa. ʻO ka mea mua, e hoʻoholo i ka ʻōnaehana e pono ai ka hoʻohana ʻana i ka defoamer, inā he ʻōnaehana wai a i ʻole ka ʻaila. No ka laʻana, i ka ʻoihana fermentation, nā defoamers ma muli o ka aila e like mePono e hoʻohana i ka silicone polyether-modified a i ʻole polyether. Pono ka ʻoihana hoʻoheheʻe wai e hoʻohana i nā defoamers pili wai a me nā defoamers silicone. E koho i ka defoamer, e hoohalike i ka huina hoonui, a e nana i ke kumukuai no ka loaa ana o ka huahana defoamer kupono loa.
Hoʻokaʻawale: Aia kekahi mau kumuwaiwai ma kēia kahua mai ka Pūnaewele a i hāʻawi ʻia e nā ʻoihana. Noho kūʻokoʻa mākou i nā manaʻo ma ka ʻatikala. No ka ʻatikala a kamaʻilio wale nō kēia ʻatikala a ʻaʻole hiki ke hoʻohana ʻia no nā kumu kūʻai. No ka mea kākau kumu ke kuleana kope. Inā loaʻa kekahi hewa, e ʻoluʻolu e kelepona mai iā mākou e holoi. Mahalo iā ʻoe no kou nānā a kākoʻo!
