He aha ka Silicone Antifoam

Hoʻokumu ʻia nā antifoams silicone me ka silica hydrophobized i hoʻopuehu maikaʻi ʻia i loko o kahi wai silicone. A laila hoʻokūpaʻa ʻia ka hui hopena i loko o kahi emulsion ma muli o ka wai a i ʻole ka aila. He mea maikaʻi loa kēia mau antifoams ma muli o ko lākou inertness kemika maʻamau, hiki i nā haʻahaʻa haʻahaʻa, a me ka hiki ke hoʻolaha ma luna o kahi kiʻiʻoniʻoni. Inā pono, hiki ke hoʻohui ʻia me nā mea paʻa hydrophobic a me nā wai e hoʻomaikaʻi ai i kā lākou waiwai defoaming.

Hoʻohana pinepine ʻia nā mea hana antifoam silicone. Ke hana nei lākou ma ka wāwahi ʻana i ka ʻāʻī o ka ʻili a me ka hoʻohaumia ʻana i nā ʻōhū puaʻa, e alakaʻi ana i ko lākou hāʻule ʻana. Kōkua kēia hana i ka hoʻopau wikiwiki ʻana i ka ʻūhā e kū nei a kōkua pū hoʻi i ka pale ʻana i ka hoʻokumu ʻana o ka ʻōpala.

Nā pōmaikaʻi o ka silicone defoamer

• 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 nā hui polar, ʻaʻole hoʻi me nā hydrocarbons a i ʻole nā ​​​​mea kūlohelohe i loaʻa nā pūʻulu hydrocarbon. No ka mea ʻaʻole hiki ke hoʻoheheʻe ʻia ka ʻaila silicone i nā mea he nui, ʻo ka silicone defoamer ka nui o nā noi. Hiki ke hoʻohana ʻia ʻaʻole wale no ka hoʻoheheʻe ʻana i nā ʻōnaehana wai, akā no nā ʻōnaehana ʻaila.

• Haʻahaʻa haʻahaʻa ili

He 20-21 dynes/cm ka ʻili o ka ʻili o ka ʻaila silicone a ʻoi aku ka liʻiliʻi ma mua o ka neʻe ʻana o ka wai (72 dynes/cm) a me nā wai huʻihaʻi maʻamau, e hoʻomaikaʻi ana i ka hopena mana o ka foam.

• Paʻa wela maikaʻi

ʻO ka lawe ʻana i ka ʻaila dimethyl silicone maʻamau e like me ke ʻano, hiki i kona kūpaʻa mahana lōʻihi ke hiki i 150 ° C, a hiki i kona kūpaʻa mahana pōkole ke piʻi ma luna o 300 ° C, e hōʻoia ana e hiki ke hoʻohana ʻia nā mea hoʻoheheʻe silicone i kahi ākea ākea.

• Paʻa kemika maikaʻi

ʻO ka ʻaila silikoni ka paʻa kemika kiʻekiʻe a paʻakikī ke hana kemika me nā mea ʻē aʻe. No laila, ʻoiai he kūpono ka hoʻomākaukau ʻana, ua ʻae ʻia nā mea hoʻoheheʻe silicone e hoʻohana ʻia i nā ʻōnaehana i loaʻa nā waikawa, alkalis, a me nā paʻakai.

• Inertia kino

Ua hōʻike ʻia ka aila silikoni he mea ʻawaʻawa ʻole i nā kānaka a me nā holoholona. No laila, hiki ke hoʻohana palekana ʻia nā defoamers silicone (me nā emulsifiers non-toxic kūpono, a me nā mea ʻē aʻe) i loko o ka pulp a me ka pepa, ka hoʻoponopono ʻana i nā meaʻai, nā lāʻau lapaʻau, nā lāʻau lapaʻau a me nā mea hoʻonaninani.

• Ka defoaming ikaika

ʻAʻole hiki i ka Silicone defoamers ke wāwahi wale i ka ʻōhū i makemake ʻole ʻia, akā ke kaohi nui ʻana i ka pua a pale i ka hoʻokumu ʻana o ka pua. He liʻiliʻi loa ke ʻano, a hoʻokahi miliona wale nō (1 ppm a i ʻole 1 g/m3) o ke kaumaha o ka mea hoʻohua e hiki ke hoʻohui ʻia e hana i kahi hopena defoaming. ʻO kona laulā maʻamau he 1 a 100 ppm. ʻAʻole wale ka haʻahaʻa o ke kumukūʻai, akā ʻaʻole ia e hoʻohaumia i nā mea i hoʻopau ʻia.

Hoʻohanohano ʻia nā antifoams silicone no ko lākou kūpaʻa, ka hoʻohālikelike ʻana me nā mea like ʻole, a me ka maikaʻi i nā haʻahaʻa haʻahaʻa. Eia nō naʻe, he mea nui e hōʻoia i ka hoʻokō ʻana i nā kūlana hoʻoponopono a kūpono i ka noi kikoʻī e pale aku i nā hopena ʻino i ka maikaʻi o ka huahana a i ʻole ke kaiapuni.
