V. Organic Silicon Antifoamer
ʻO Polydimethylsiloxane, i ʻike ʻia he ʻaila silicone, ʻo ia ka mea nui o ka silicone defoamer.Ke hoʻohālikelike ʻia me ka wai a me ka ʻaila maʻamau, ʻoi aku ka liʻiliʻi o ka ʻili o ka ʻili, kahi kūpono no ka ʻōnaehana hoʻoheheʻe wai a me ka ʻōnaehana ʻaila.He hana kiʻekiʻe ka ʻaila silikoni, haʻahaʻa haʻahaʻa, paʻa nā waiwai kemika, ka laulā noi māmā, haʻahaʻa volatility, non-toxic, a me ka mana defoaming koʻikoʻi.ʻO ka hemahema ʻo ka hana ʻino ʻole o ka foam inhibition.
1. Antifoamer paʻa
Loaʻa i ka Solid Antifoamer nā hiʻohiʻona o ke kūpaʻa maikaʻi, ka hana maʻalahi, ka lawe maʻalahi a me ka hoʻohana maʻalahi.He kūpono ia no ka ʻaila ʻaila a me ka wai, a ʻo ke ʻano hoʻopuehu waena ke kaulana.Hoʻohana nui ʻia ia ma ke kahua o ka ʻūhā haʻahaʻa a i ʻole ka pauka holoi holoi ʻole.
2. Emulsion Antifoamer
ʻO ka ʻaila silicone i loko o ka emulsion defoamer ʻoi aku ka ʻoi aku ka nui o ka haʻalulu, a ʻoi aku ka nui o ka coefficient emulsification.Ke koho pono ʻole ʻia ka emulsifier, e hoʻoneʻe ʻia ka mea hoʻoheheʻe defoaming a me ka metamorphic i ka manawa pōkole.He mea koʻikoʻi ka paʻa o ka emulsion i ka maikaʻi o ka mea hoʻoheheʻe.No laila, ʻo ka hoʻomākaukau ʻana o ka emulsion type silicone defoamer e kau ana i ke koho o ka emulsifier.I ka manawa like, ʻo ka emulsion defoamer ka mea nui loa i ka silicone defoamer me nā hiʻohiʻona o ke kumukūʻai haʻahaʻa, ka laulā noi ākea, ka hopena defoaming maopopo, a pēlā aku.Me ka holomua o ka ʻenehana formulation, e ulu nui ka emulsion defoamer.
3. Hoʻonā Antifoamer
He hopena ia i hana ʻia e ka hoʻoheheʻe ʻana i ka aila silicone i ka solvent.ʻO kāna kumu defoaming ʻo ia ka lawe ʻia ʻana o nā ʻāpana aila silicone e ka solvent a hoʻopuehu ʻia i loko o ka ʻūhā.Ma kēia kaʻina hana, e hoʻokuʻu mālie ka ʻaila silicone i loko o nā droplets e hoʻopau i ka defoaming.ʻO ka ʻaila silikoni i hoʻoheheʻe ʻia i loko o ka ʻōnaehana hoʻonā wai wai ʻole, e like me polychloroethane, toluene, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia e like me ka hoʻoheheʻe ʻana i ka aila.
4. Aila Antifoamer
ʻO ka mea nui o ka aila defoamer ʻo ka ʻaila silicone dimethyl.ʻAʻohe hopena defoaming maʻemaʻe dimethyl silicone a pono e emulsified.Hoʻemi wikiwiki ka ʻili o ka silicone emulsified, a hiki i kahi mea liʻiliʻi ke hoʻokō i ka haki ʻana a me ka inhibition ikaika.Ke hui pū ʻia ka ʻaila silicone me kahi ʻāpana o nā mea kōkua silica hydrophobically i mālama ʻia, hiki ke hana ʻia kahi ʻaila hui defoamer.Hoʻohana ʻia ʻo Silicon dioxide i mea hoʻopihapiha, no ka mea, hiki i ka nui o nā hui hydroxyl ma luna o kona ʻili ke hoʻonui i ka mana dispersing o ka ʻaila silicone i loko o ka ʻōnaehana foaming, e hoʻonui i ka paʻa o ka emulsion, a maopopo ka hoʻomaikaʻi ʻana i ka waiwai defoaming o ka silicone defoamer.
No ka mea he lipophilic ka aila silicone, he hopena defoaming maikaʻi loa ka silicone defoamer ma ka ʻaila-soluble solution.Eia naʻe, pono e noʻonoʻo ʻia kēia mau mea i ka wā e hoʻohana ai i ka silicone defoamer:
● Low viscosity silicone defoamer he maikaʻi defoaming hopena, akā, kona hoʻomau 'ana ua ilihune;Loaʻa i ka defoamer silicone viscosity kiʻekiʻe ka hopena defoaming akā maikaʻi ka hoʻomau.
● Inā haʻahaʻa ka viscosity o ka solution foaming, ʻoi aku ka maikaʻi o ke koho ʻana i ka silicone defoamer me ka viscosity kiʻekiʻe.ʻO ka mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka viscosity o ka solution foaming, ʻoi aku ka maikaʻi o ke koho ʻana i ka silicone defoamer me ka viscosity haʻahaʻa.
● ʻO ke kaumaha o ka molecular o ka oily silicone defoamer kekahi mana i kona hopena defoaming.
● ʻO ka defoamer me ke kaumaha molekala haʻahaʻa he maʻalahi ke hoʻopuehu a hoʻoheheʻe, akā nele i ka hoʻomau.Ma ka ʻokoʻa, ʻilihune ka hana defoaming o ka defoamer kaumaha molecular kiʻekiʻe, a paʻakikī ka emulsification, akā ʻilihune ka solubility a maikaʻi ka lōʻihi.
