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 ka laulā 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 kekahi 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, 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!
