Siliconedefoamerhe emulsion viscous keʻokeʻo. Ua hoʻohana ʻia ia ma nā ʻano ʻoihana like ʻole mai ka makahiki 1960, akā ua hoʻomaka ka hoʻomohala wikiwiki nui a me ka hoʻomohala ʻana i nā makahiki 1980. Me he organosilicondefoamer, ʻo kāna mau kahua noi he ākea loa, e ʻimi nui ana i ka nānā ʻana mai nā ʻano āpau o ke ola. I loko o ka kemika, pepa, uhi, meaʻai, textile, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe, siliconedefoamerhe mea hoʻohui pono i ka hana hana. ʻAʻole hiki iā ia ke hoʻoneʻe wale i ka ʻūhā ma ka ʻili wai o ke kaʻina hana i ke kaʻina hana, no laila e hoʻomaikaʻi ai i ka kānana, ʻO ka hoʻokaʻawale ʻana, gasification, a me nā hopena wai wai o ka holoi ʻana, extraction, distillation, evaporation, dehydration, maloʻo a me nā hana ʻenehana ʻē aʻe e hōʻoia i ka ka mana o nā mea like ʻole o ka mālama ʻana a me ka hana ʻana i nā ipu.

Pono osilicone defoamers:
1. Ka laulā o nā noi: ma muli o ke ʻano kemika kūikawā o ka ʻaila silicone, ʻaʻole kūpono ia me ka wai a i ʻole nā ​​mea i loaʻa i nā pūʻulu polar, ʻaʻole hoʻi me nā hydrocarbons a i ʻole nā ​​mea kūlohelohe i loaʻa nā hui hydrocarbon. Ma muli o ka insolubility o ka ʻaila silicone i nā ʻano mea like ʻole, loaʻa iā ia kahi ākea o nā noi. Hiki ke hoʻohana ʻia no ka defoaming i nā ʻōnaehana wai a me nā ʻōnaehana ʻaila.
2. Haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa: ʻO ka ili o ka ʻaila silicone ma ke ʻano he 20-21 dyne / cm, ʻoi aku ka liʻiliʻi ma mua o ka wai (72 dyne / cm) a me nā wai huʻihaʻi maʻamau, a he hana defoaming maikaʻi.
3. ʻO ke kūpaʻa wela maikaʻi: ʻO ka lawe ʻana i ka simethicone i hoʻohana mau ʻia ma ke ʻano he laʻana, hiki iā ia ke kū i ka 150 ° C no ka manawa lōʻihi a me 300 ° C no ka manawa pōkole, a ʻaʻole e decompose kāna paʻa Si-O. Hōʻoia kēia i kasilicone defoamerhiki ke hoʻohana ʻia ma kahi ākea ākea.
4. Paʻa kemika maikaʻi: No ka paʻa ʻana o ka paʻa Si-O, ʻoi aku ka kiʻekiʻe o ka paʻa kemika o ka ʻaila silicone, a paʻakikī ke hoʻopili kemika me nā mea ʻē aʻe. No laila, ʻoiai he kūpono ka hoʻopuka ʻana,nā mea hoʻoheheʻe siliconeʻae ʻia e hoʻohana ʻia i nā ʻōnaehana i loaʻa nā waikawa, alkalis, a me nā paʻakai.
5. Physiologically inert: Ua hōʻike ʻia ka ʻaila silikoni i mea ʻole i nā kānaka a me nā holoholona, ​​a ʻoi aku ka hapa o ka make ma mua o 34 g / kg. No laila,nā mea hoʻoheheʻe silicone(me nā emulsifiers non-toxic kūpono, a me nā mea ʻē aʻe) hiki ke hoʻohana pono ʻia i nā ʻoihana meaʻai, lāʻau lapaʻau, lāʻau lapaʻau a me nā ʻoihana hoʻonaninani.
6. ikaika defoaming mana:Mea hoʻoheheʻe silikoniʻAʻole hiki ke uhaʻi wale i ka ʻūhā i hana ʻia, akā hiki nō hoʻi ke kāohi nui i ka ʻōpū a pale i ka hoʻokumu ʻana o ka pua. He liʻiliʻi loa kona hoʻohana ʻana, ʻoiai ka lōʻihi o ka hoʻohui ʻana i hoʻokahi hapa o ka miliona (1ppm) o ke kaumaha o ka mea hoʻohua, hiki iā ia ke hana i ka hopena defoaming. ʻO kāna laulā maʻamau ʻo 1 a 100 ppm. ʻAʻole wale ka haʻahaʻa o ke kumu kūʻai, akā ʻaʻole hoʻi e hoʻohaumia i ka mea defoamed.

Nā hemahema onā mea hoʻoheheʻe silicone:
a. He paʻakikī ka hoʻopuehu ʻana o Polysiloxane: He paʻakikī ke hoʻoheheʻe ʻia ʻo Polysiloxane i ka wai, kahi e pale ai i kona hoʻopuehu ʻana i ka ʻōnaehana wai. Pono e hoʻohui i kahi mea hoʻopuehu. Inā hoʻohui ʻia ka mea hoʻopuehu, e paʻa ka emulsion a e loli ka hopena defoaming. ʻAʻole pono, pono e hoʻohana i ka emulsifier liʻiliʻi e hana i ka hopena defoaming maikaʻi a paʻa ka emulsion.
b. ʻO ka Silicone ka ʻaila-soluble, e hōʻemi ana i kona hopena defoaming i ka ʻōnaehana ʻaila.
c. ʻO ke kūpaʻa wela kiʻekiʻe lōʻihi a me ke kūpaʻa alkali maikaʻi ʻole.
