He aha ka Silicone Antifoam

ʻO ka maʻamau, ua hana ʻia nā antifoams silicone me ka silica hydrophobized i hoʻopuehu maikaʻi ʻia i loko o kahi wai silicone. A laila hoʻopaʻa ʻia ka hui hopena i loko o kahi emulsion wai a i ʻole ka ʻaila. He kūpono loa kēia mau antifoams ma muli o ko lākou inertness kemika maʻamau, ka ikaika ʻoiai i nā ʻano haʻahaʻa, a me ka hiki ke hohola ma luna o kahi ʻili foam. Inā pono, hiki ke hoʻohui ʻia me nā mea paʻa hydrophobic a me nā wai ʻē aʻe e hoʻomaikaʻi i ko lākou mau waiwai defoaming.

Makemake pinepine ʻia nā mea antifoam silicone. Hana lākou ma ka uhaki ʻana i ka ʻili o ka ʻili a me ka hoʻopaʻa ʻana i nā pehu huʻa, e alakaʻi ana i ko lākou hiolo ʻana. Kōkua kēia hana i ka hoʻopau koke ʻana i ka huʻa e kū nei a kōkua pū kekahi i ka pale ʻana i ka hoʻokumu ʻia ʻana o ka huʻa.

Nā pōmaikaʻi o ka silicone defoamer

• Ka laulā o nā noi

Ma muli o ke ʻano kemika kūikawā o ka ʻaila silicone, ʻaʻole ia e kūlike me ka wai a i ʻole nā ​​​​mea i loaʻa nā hui polar, ʻaʻole hoʻi me nā hydrocarbons a i ʻole nā ​​​​mea olaola i loaʻa nā hui hydrocarbon. ʻOiai ʻaʻole hiki ke hoʻoheheʻe ʻia ka ʻaila silicone i nā mea he nui, he ākea nā noi o ka silicone defoamer. Hiki ke hoʻohana ʻia ʻaʻole wale no ka hoʻoheheʻe ʻana i nā ʻōnaehana wai, akā no nā ʻōnaehana ʻaila hoʻoheheʻe.

• Haʻahaʻa ka ʻilikai

ʻO ka ʻili o ka ʻaila silicone maʻamau he 20-21 dynes/cm a ʻoi aku ka liʻiliʻi ma mua o ka ʻili o ka wai (72 dynes/cm) a me nā wai huʻa maʻamau, kahi e hoʻomaikaʻi ai i ka hopena kaohi huʻa.

• Paʻa maikaʻi o ka wela

Ma ke ʻano he laʻana, hiki i kona kūpaʻa wela lōʻihi ke piʻi i 150°C, a hiki i kona kūpaʻa wela pōkole ke piʻi ma luna o 300°C, e hōʻoiaʻiʻo ana e hiki ke hoʻohana ʻia nā mea hoʻoheheʻe silicone ma kahi ākea o ka mahana.

• Paʻa maikaʻi o ke kemika

He kiʻekiʻe ke kūpaʻa kemika o ka ʻaila silicone a he paʻakikī ke hana kemika me nā mea ʻē aʻe. No laila, inā kūpono ka hoʻomākaukau ʻana, ʻae ʻia nā mea hoʻohemo silicone e hoʻohana ʻia i loko o nā ʻōnaehana e loaʻa ana nā waikawa, alkalis, a me nā paʻakai.

• Ka inertia kino

Ua hōʻoia ʻia ka ʻaila silicone ʻaʻole ia he mea ʻawahia i nā kānaka a me nā holoholona. No laila, hiki ke hoʻohana palekana ʻia nā mea hoʻohemo silicone (me nā emulsifiers ʻawahia ʻole kūpono, a pēlā aku) i ka pulp a me ka pepa, ka hana ʻana i ka meaʻai, nā hana lapaʻau, nā lāʻau lapaʻau a me nā hana hoʻonaninani.

• Hoʻopau ikaika i ka huʻa

ʻAʻole hiki i nā mea hoʻohemo hua silicone ke uhaʻi wale i ka huʻa makemake ʻole ʻia, akā hiki nō hoʻi ke kāohi nui i ka huʻa a pale i ka hoʻokumu ʻia ʻana o ka huʻa. He liʻiliʻi loa ka nui o ka lāʻau, a hoʻokahi miliona wale nō (1 ppm a i ʻole 1 g/m3) o ke kaumaha o ka mea hoʻohua hiki ke hoʻohui ʻia e hana i kahi hopena hoʻohemo hua. ʻO kona pae maʻamau he 1 a 100 ppm. ʻAʻole wale ke kumukūʻai haʻahaʻa, akā ʻaʻole ia e hoʻohaumia i nā mea e hoʻohemo hua ʻia ana.

Ua mahalo ʻia nā antifoams silicone no ko lākou kūpaʻa, kūlike me nā mea like ʻole, a me ka pono i nā ʻano haʻahaʻa. Eia nō naʻe, he mea nui e hōʻoia i ko lākou kūlike me nā kūlana hoʻoponopono a kūpono no ka hoʻohana kikoʻī e pale aku i nā hopena maikaʻi ʻole i ka maikaʻi o ka huahana a i ʻole ke kaiapuni.
