ʻOkoʻa ka ʻokoʻa o ka ʻāpana EO ma kekahi mau helu, no ke aha e loli nui ai ka hana o ka formulation? — Ke hoʻomaopopo nei i ke koho ʻana o ka momona amine ether me Qixuan TA05

I ka wā o nā hālāwai koho surfactant, kū pinepine kahi pilikia maʻamau: ʻelua mau momona amine polyoxyethylene ethers me kahi ʻokoʻa iki wale nō i nā ʻāpana ethylene oxide (EO) a me nā hōʻailona kumukūʻai like hiki ke hāʻawi i nā hopena ʻokoʻa loa ke hoʻokomo ʻia i loko o nā ʻano hana. E loli maopopo ka paʻa o ka emulsion, ka viscosity o ka ʻōnaehana a me ke kala o ka huahana i hoʻopau ʻia. I ka lawelawe ʻana i nā mea kūʻai aku ma waena o ka hoʻomaʻemaʻe ʻana, ke kahua ʻaila, ka emulsification agrochemical, ka asphalt, ka hana mineral a me nā ʻāpana ʻē aʻe, ua nīnau pinepine ʻia ka hui loea o Shanghai Qixuan Chemical Technology Co., Ltd. i hoʻokahi nīnau koʻikoʻi: pehea e koho ai i ka helu EO kūpono?

TA05, ʻo ia hoʻi ka tallow amine polyoxyethylene (5) ether, hāʻawi i kahi hopena koho no kēia nīnau. ʻAʻole ia e alualu i ka hana koʻikoʻi ma kahi hōʻailona hoʻokahi, akā loaʻa iā ia kona kūlana hilinaʻi i loko o kahi ākea ākea o nā ʻōnaehana noi like ʻole.

Hoʻohui ʻia ʻo TA05 e ka ethoxylation o ka amine tallow kūlohelohe me 5 mau ʻāpana EO, CAS No. 61791-26-2. ʻO kona ʻāpana hydrophobic i hui pū ʻia me nā kaulahao alkyl C16-C18 lōʻihi, ʻoiai ʻo ka ʻāpana hydrophilic i hāʻawi pū ʻia e ʻelima mau ʻāpana EO a me kahi hui amine protonatable.

Hāʻawi kēia ʻano hana kūikawā iā ia me nā ʻano hana pālua. Ma lalo o nā kūlana kūlike ʻole a alkaline paha, hana ia ma ke ʻano he surfactant nonionic, e hoʻokō ana i ka emulsification a me ka hoʻolaha ʻana ma o ka hydration o nā kaulahao EO. I loko o nā wahi waikawa, hoʻopili ʻia ka hui amine a lawe i nā uku maikaʻi, e hōʻike ana i nā ʻano surfactant cationic me ka ikaika adsorption affinity i nā substrates i hoʻopiʻi maikaʻi ʻole ʻia e like me nā ʻili metala, nā minelala, nā fibers a me nā ʻāpana asphalt. ʻO kēia ʻano hana pālua i loko o hoʻokahi molekala ke kumu nui e hoʻohana pinepine ʻia ai ʻo TA05 ma nā ʻoihana he nui.

Ma ke ʻano o nā waiwai kino, ʻike ʻia ʻo TA05 ma ke ʻano he wai ʻālohilohi melemele a ʻeleʻele paha ma 25°C. ʻO kona hopena wai 1% he alkaline me ka pH mai 9 a 11. ʻO ka waiwai amine holoʻokoʻa e kāohi maʻamau ʻia ma waena o 110-120 mgKOH/g, ka makū ≤1.0%, ke kala Gardner ≤10, a ʻo ka waiwai HLB ma kahi o 9. Aia kēia HLB ma ka palena ma waena o ka hydrophilicity a me ka lipophilicity, e hiki ai iā ia ke hoʻoheheʻe maikaʻi i nā pae aila i ka wā e neʻe ana i nā pilina aila-wai. No laila, kūpono ia no ka emulsification W/O, co-emulsification a me ka hoʻomaʻū ʻana o ka interfacial, ma mua o ka lawelawe ʻana ma ke ʻano he emulsifier aila-i-ka-wai maʻalahi.

Hiki ke hoʻololi ʻia kahi mea hānai amine tallow hoʻokahi i loko o nā papa serial me 2, 5, 10, 15 mau ʻāpana EO, e hāʻawi ana i nā waiwai like ʻole. ʻO nā helu EO haʻahaʻa e lawe mai i ka lipophilicity ikaika, ka waiwai amine kiʻekiʻe a me ka solubility wai ʻilihune; ʻoi aku ka nui o nā mea EO e hoʻomaikaʻi i ka solubility wai a hoʻololi i ka makemake emulsifying i nā ʻōnaehana O/W.

ʻOi aku ka nui o ka hoʻoheheʻe ʻia o ka papa 2 EO, e koi ana i ka hoʻoheheʻe ʻana o ka solvent a i ʻole ka hoʻomehana ʻana no ka hoʻopuehu ʻana i nā ʻano hana he nui. Hōʻike nā papa me 10 a ʻoi aku paha nā ʻāpana EO i ka solubility wai maikaʻi akā ua nāwaliwali ka pilina interfacial i nā ʻōnaehana ʻaila kiʻekiʻe, nā ʻōnaehana paʻa kiʻekiʻe. Hoʻokuʻi nā ʻāpana EO ʻelima i kahi kahua waena kaulike: mālama ia i nā ʻāpana lipophilic lawa e hoʻopaʻa ai ma luna o ka ʻaila, asphalt a me nā ʻili mineral, ʻoiai he mana hydrophilic kumu no ka hoʻolaha ʻana i nā media wai. No nā noi e koi ana i ka emulsification a me ka adsorption, ke kaulike nei i ka lipophilicity a me ka hoʻopuehu ʻana o ka wai, ʻoi aku ka maikaʻi o kēia papa ma mua o nā papa ma kēlā me kēia ʻaoʻao o ka spectrum EO.

ʻO ia kekahi kumu e manaʻo nui ʻia ai ʻo TA05 he "mea hoʻohui formulation". Hiki ke hoʻoponopono ʻia kona solubility wai a me ke kiko ao ma ka hui ʻana me nā analogues EO kiʻekiʻe, ʻoiai hiki ke hoʻonui ʻia ka hana lipophilic ma ka hui pū ʻana me nā ʻano EO haʻahaʻa. I loko o nā ʻōnaehana hui, hana ia ma ke ʻano he poloka kūkulu maʻalahi no ka hoʻoponopono ʻana i ka formulation, ʻoi aku ka waiwai ma ke ʻano he co-component ma mua o kahi mea hana mua kū hoʻokahi.

Ma waho aʻe o nā ʻāpana i luna, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui antistatic a palupalu i ka hana ʻana i ka lole ma o ka adsorbing ma luna o nā ʻili fiber ma o nā hui amine protonated. I ka flotation mineral, hana ia ma ke ʻano he mea hōʻiliʻili kōkua a i ʻole dispersant e hilinaʻi ana i ka adsorption cationic kuhikuhi ma nā ʻili mineral.

No nā amine ethoxylates momona, ʻo ka hoʻokō ʻana i nā paepae kikoʻī wale nō ke koi komo. ʻO ka mea e hoʻomalu maoli i ke kūpaʻa o ka formulation no nā mea kūʻai aku hope loa, ʻo ia ka hāʻawi ʻana o EO haiki, ka PEG manuahi i kāohi ʻia a me ka ʻike EO manuahi, a me ke kala paʻa ma luna o ka mālama ʻana. ʻO ka hāʻawi ʻana o EO ākea e alakaʻi i ka loli o ka emulsifying capacity a me ka solubility wai me nā waiwai amine like. ʻO nā formulations i hoʻomaikaʻi ʻia ma ka pae lab e hāʻule pinepine i ka wā o ka pilot a i ʻole ka hana piha.

Ma Qixuan, uhi nā ʻōkuhi mana koʻikoʻi no TA05 i ka waiwai amine, ka makū, ka pH a me ke kala, me ka hoʻāʻo piha ʻana o ka puʻupuʻu a me ka paʻa ʻana o ka laʻana no ka hiki ke hahai ʻia. ʻO ka ʻōpala maʻamau he 180 kg no kēlā me kēia pahu, ʻoiai e loaʻa ana ka ʻeke IBC a me ka ʻōpala OEM i hana ʻia ma ke noi.

• [1] E wehewehe i ka puka makani pH ma mua o ka loiloi hoʻohālikelike:Hana ʻo TA05 ma ke ʻano he cationic ma lalo o nā kūlana acidic a me ka nonionic ma lalo o nā kūlana alkaline. ʻOkoʻa loa kona mau hoa kūpono, ke kaʻina hānai a me ka nui i ʻōlelo ʻia ma waena o kēia mau wahi ʻelua.

ʻO ke koho ʻana o ka Surfactant ke ʻimi nei i kahi kūpono loa ma kahi piʻo hoʻonohonoho EO hoʻomau. ʻAʻole moe ka pono o TA05 i ka hana kiʻekiʻe loa ma kahi waiwai hoʻokahi, akā e noho ana i kēlā wahi waena i nānā pinepine ʻole ʻia e kaulike ana i ka lipophilicity a me ka hydrophilicity me nā koi mākeke kūpono he nui.

Hāʻawi ʻo Shanghai Qixuan Chemical Technology Co., Ltd. i kahi moʻo piha o nā papa tallow amine polyoxyethylene ether. Ua mākaukau mākou e hāʻawi i nā ʻano EO i hana kūikawā ʻia a me ke kākoʻo loea noi ʻoihana e kūlike ana i kāu mau koi hoʻohui kikoʻī.
