Hiki ke hoʻokaʻawale ʻia nā mea hana defoaming maʻamau i ke silika (resin), surfactants, alkane a me ka ʻaila mineral e like me nā ʻāpana like ʻole.
1, papa silika (resin).
ʻIke ʻia ʻo Silicone defoaming agent ma ke ʻano he emulsion type defoaming agent.ʻO ke ala e hoʻohana ai, ʻo ia ka emulsify silicone me ka emulsifying agent (surfactant) a hoʻopuehu i loko o ka wai a laila hoʻohui i ka wai ʻino.ʻO ka pauka silica kekahi ʻano defoamer silika me ka hopena defoaming ʻoi aku ka maikaʻi.
2, papa surfactant
ʻO kēia ʻano mea hoʻoheheʻe he emulsifier maoli, e hoʻohana i ka hana dispersive o ka mea hana ʻili, ʻo ia hoʻi, e hana i ka mea i hana ʻia e mālama ai i ka emulsification state dispersing i loko o ka wai, e pale i ka hana ʻana i ka huʻa ma laila.
3. Paraffins
Hana ʻia ka mea hoʻoheheʻe paraffin me ka paraffin paraffin wax a i ʻole kona derivative emulsified a hoʻopuehu ʻia e ka emulsifying agent.Ua like kona hoʻohana me ka emulsified defoaming agent o surfactant.
4. ʻAila mineral
ʻO ka ʻaila mineral ka defoamer nui.I mea e hoʻomaikaʻi ai i ka hopena, hui pū ʻia me ke kopa metala, ʻaila silicone, silicon dioxide a me nā mea ʻē aʻe i hoʻohana pū ʻia.Eia kekahi, i mea e maʻalahi ai ka hoʻoheheʻe ʻana i ka ʻaila mineral i ka ʻili o ka wai huʻihuʻi, a i ʻole e hoʻopuehu like ʻia ke kopa metala i loko o ka ʻaila mineral, i kekahi manawa hiki ke hoʻohui i nā ʻano surfactants.
ʻO nā pono a me nā pōʻino o nā ʻano mea hoʻoheheʻe
ʻO kaʻaila mineral, ka amide, ka waiʻona haʻahaʻa, ka momona momona a me ka momona momona ester, phosphate ester a me nā mea noiʻi defoaming ʻē aʻe ma mua, no ka hanauna mua o ka defoaming agent, loaʻa iā ia nā pōmaikaʻi o ka maʻalahi o ke komo ʻana i nā mea maka, kiʻekiʻe ka hana kaiapuni. , uku hana haʻahaʻa;Aia ka hemahema i ka pono defoaming haʻahaʻa, kikoʻī ikaika a me nā kūlana hoʻohana paʻakikī.
ʻO ka polyether antifoaming agent ka lua o ka hanauna o ka antifoaming agent, ka mea nui me ka polyether kaulahao pololei, ka waiʻona a i ʻole ka amonia e like me ka mea hoʻomaka o ka polyether, polyether derivatives esterified e ka hui terminal ʻekolu.ʻO ka polyether defoaming agent ka mea maikaʻi loa o ka hiki ke hoʻopaʻa i ka foam ikaika, ʻo ia hoʻi, aia kekahi polyether defoaming agent me ke kūpaʻa wela kiʻekiʻe, kūʻē i ka waikawa ikaika a me ka alkali a me nā hana maikaʻi ʻē aʻe;Hoʻopili ʻia nā hemahema e ka mahana, ke kahua haʻiki o ka hoʻohana ʻana, ka hiki ke defoaming maikaʻi ʻole a me ka helu haʻahaʻa haʻahaʻa haʻahaʻa.
Silicone defoaming agent (ke kolu o ka hanauna o defoaming agent) he ikaika defoaming hana, hiki wawe ka defoaming, haʻahaʻa volatility, non-toxic i ke kaiapuni, ʻaʻohe physiological inertia, ākea ka hoʻohana ʻana a me nā pono ʻē aʻe, no laila he ākea ka manaʻo noi a me ka nui. hiki i ka mākeke, akā ʻilihune ka hana anti-foaming.
ʻO ka polyether modified polysiloxane defoaming agent ka mea maikaʻi o ka polyether defoaming agent a me ka silicone defoaming agent i ka manawa like, ʻo ia ke kuhikuhi o ka hoʻomohala ʻana o ka mea hoʻopau defoaming.I kekahi manawa hiki ke hoʻohana hou ʻia e like me kona inverse solubility, akā i kēia manawa aia kekahi mau ʻano o ia defoaming agents, aia nō i ka pae noiʻi a me ka hoʻomohala ʻana, a he kiʻekiʻe ke kumu kūʻai.
