ʻO ke kolu o ka hanauna defoamer he silicone defoamer e pili ana i ka polydimethylsiloxane (PDMS, dimethyl silicone oil).I kēia manawa, ʻo ka noiʻi ʻana a me ka hoʻohana ʻana o kēia hanauna o nā defoamers ke kumu nui ma Kina.Hoʻokumu ʻia ʻo PDMS i ke kaulahao oxygen silicon a me nā hui kūlohelohe ʻē aʻe, a ʻaʻole hiki ke hoʻonohonoho paʻa ʻia ma ke kiʻi ʻoniʻoni wai puna, no laila e pohā nā ʻōpū.Loaʻa i ka PDMS viscosity haʻahaʻa ka waiwai defoaming maikaʻi a me ka PDMS viscosity kiʻekiʻe he waiwai defoaming maikaʻi.
ʻO nā pono o ka silicone defoamer
Loaʻa iā ia ka inertia kemika maikaʻi a paʻakikī ke hana me nā mea ʻē aʻe.Hiki ke hoʻohana ʻia i ka waika, alkali a me ka paʻakai.
ʻO ka inertia physiological maikaʻi, hiki ke hoʻohana ʻia i nā ʻoihana meaʻai a me nā lāʻau lapaʻau, a ʻaʻohe haumia i ke kaiapuni.
Loaʻa iā ia ka paʻa wela maikaʻi a me ka volatility haʻahaʻa, a hiki ke hoʻohana ʻia i kahi ākea ākea.
He haʻahaʻa ka viscosity a laha wikiwiki i ka interface kinoea-wai.
ʻO ka haʻahaʻa haʻahaʻa e like me 1.5-20 Mn / M (76 Mn / m no ka wai).
ʻAʻole maʻalahi ka hoʻoheheʻe ʻia e ka surfactant ma ka ʻōnaehana foaming.
Haʻahaʻa haʻahaʻa, haʻahaʻa viscosity a haʻahaʻa flammability.
Nā hemahema o ka silicone defoamer
1. He paʻakikī ka hoʻopuehu ʻana i ka ʻōnaehana wai.
2. No ka mea hiki ke hoʻoheheʻe ʻia i ka ʻaila, hoʻemi ʻia ka hopena defoaming i ka ʻōnaehana ʻaila.
3. Poor kiʻekiʻe wela kū'ē.
4. Ke kū'ē maikaʻiʻole i ka alkalinity ikaika.
Ke kumu kūʻai nui:ʻO ka PDMS he wai i loko o kaʻaila (O / W) emulsion i hanaʻia me kaʻaila silicone, emulsifier, thickener, a me nā mea'ē aʻe, i hoʻopiliʻia e ka wai.E emi koke ana ka haʻalulu o ka ʻili a loaʻa nā hopena anti foaming a me nā hopena anti foaming.Hoʻokaʻawale ʻia ia i ʻekolu mau ʻano: ʻaila silicone, ʻaila silicone + polyether i hoʻololi ʻia a me ka ʻaila silicone i hoʻololi ʻia.
Hōʻike ʻia ia e:ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa, ka hana ʻili kiʻekiʻe a me ka mana defoaming ikaika.
ʻOi aku ka liʻiliʻi:Hiki iā ia ke keʻakeʻa a uhaʻi i nā ʻōhū no ka hapa nui o nā media bubble.Loaʻa iā ia ke kūpaʻa wela maikaʻi a hiki ke hoʻohana ʻia ma kahi ākea ākea.Hoʻokaʻawale ʻia me ka polyether a he hopena synergistic.Hoʻohana nui ʻia ia no ka defoaming i ka detergent, papermaking, pulp, sugar making, electroplating, fertilizer chemical, additives, wastewater treatment and other production process.I ka ʻoihana ʻaila, hoʻohana nui ʻia ia no ka desulfurization o ke kinoea maoli e hoʻolalelale i ka hoʻokaʻawale ʻana i ka aila;Hoʻohana ʻia ia e hoʻomalu a hoʻopaʻa i nā ʻōhū i loko o nā mea e like me ka ethylene glycol maloʻo, ka ʻili ʻana o ka hydrocarbon aromatic, ka hana asphalt a me ka hinu lubricating dewaxing.I loko o ka ʻoihana textile, hoʻohana ʻia ia no ka defoaming i ke kala ʻana, ka ʻōpala, ka nui a me nā kaʻina hana ʻē aʻe;Hoʻohana ʻia ia i ka hana o ka emulsion kemika a me ka defoaming i ka ʻoihana;Hoʻohana ʻia ia no ka defoaming i nā ʻano ʻokoʻa like ʻole, fermentation a me nā kaʻina distillation i ka ʻoihana meaʻai.
