1. Mea hoʻomaʻemaʻe kiʻekiʻe a me Colloidal Framework
1.1 Molecular Architecture o Zinc Stearate
(Ultrafine zinc stearate emulsion)
ʻO Zinc stearate kahi kopa metala i hoʻomohala ʻia e ka pane o ka waikawa stearic– he ʻakika momona saturated kaulahao lōʻihi (C ₁₇ H ₃₅ COOH)– me nā iona zinc, ke kumu o ka hui Zn(C ₁₇ H ₃₅ COO)₂.
Aia i loko o kona ʻano molekala kekahi ion zinc waena i hui pū ʻia i 2 nā kaulahao alkyl hydrophobic, ka hoʻomohala ʻana i kahi ʻano amphiphilic e hiki ai i ka hana interfacial ma nā ʻōnaehana wai a me ka polymer.
Ma ke ʻano nui, Aia ka zinc stearate ma ke ʻano he pauka waxy me ka hoʻohaʻahaʻa haʻahaʻa i ka wai a me ka hapa nui o nā mea hoʻoheheʻe maoli, kaohi ʻana i kāna noi pololei ʻana i nā hoʻonā homogeneous.
Eia naʻe, ke hana ʻia a lilo i emulsion ultrafine, ua hoʻemi ʻia ka ʻāpana bit i submicron a i ʻole ka laulā nanometer (maʻa mau 50– 500 nm), hoʻonui nui i ka hana o ka ʻili a me ka diffusion.
Hoʻonui kēia kūlana nano-dispersed i ka ʻike, hikiwawe, a me ka launa pū ʻana me nā matrices a puni, wehe ʻana i ka hana ʻoi aku ka maikaʻi ma nā noi ʻoihana.
1.2 Emulsification Mechanism a me ka Stabilization
ʻO ka hana hoʻomākaukau o ka ultrafine zinc stearate solution e pili ana i ka homogenization kiʻekiʻe-shear, microfluidization, ai 'ole ka ultrasonication o molten zinc stearate i ka wai, kōkua ʻia e nā surfactants e like me nā emulsifiers nonionic a i ʻole anionic.
Hoʻopili ka surfactants ma luna o ka ʻili o nā kulu a i ʻole nā ʻāpana, ka hoʻohaʻahaʻa ʻana i ka haʻahaʻa interfacial a me ka pale ʻana i ka coalescence ma o ka electrostatic repulsion a i ʻole steric hindrance.
Aia nā stabilizer maʻamau i nā esters sorbitan polyoxyethylene (ʻOhi ma waena), sodium dodecyl sulfate (SDS), aiʻole nā waiʻona ethoxylated, koho ʻia ma muli o ka hoʻohālikelike ʻana me ka ʻōnaehana pahuhopu.
Hiki ke hoʻohana ʻia nā ʻenehana hoʻohuli pae no ka loaʻa ʻana o ka ʻaila-i-wai (O/W) nā hāʻina me ka nui o ka ʻāpana haiki a me ka paʻa colloidal lōʻihi.
Ke hoʻomau nei nā emulsion i hana pono ʻia no nā mahina me ka ʻole o ka sedimentation a i ʻole ka hoʻokaʻawale pae, e hana i ka pono mau i ka wā o ka waiho ʻana a me ka hoʻohana ʻana.
Hiki ke hoʻonāwaliwali ʻia ka hopena a maopopo i ka wai waiu, mika, a hoʻokomo ʻia i loko o nā kaʻina hana wai, hoʻololi i nā mea hoʻoheheʻe a i ʻole ka pauka.

2.1 ʻO ka Lubrication o loko a me waho i nā Polymers
Ultrafine zinc stearate solution he mea lubricating maikaʻi loa i ka polycarbonate a me ka mālama thermoset, e hana ana ma ke ʻano he mea hoʻolaha i loko a me waho.
Ma ke ʻano he mea lubricating i loko, e ho'ēmi ana i ka viscosity hoʻoheheʻe ʻia ma ka hoʻemi ʻana i ka friction intermolecular ma waena o nā kaulahao polymer, kōkua i ke kahe ʻana i ka wā extrusion, hoʻoheheʻe ʻia, a me ka kalena.
Hoʻonui kēia i ka hiki ke hana, hoemi i ka lawe mana, a hoʻemi i ka hoʻohaʻahaʻa wela i hoʻoulu ʻia e ka hoʻoheheʻe ʻana.
Ma waho, hoʻomaka ka emulsion i kahi slim, kiʻiʻoniʻoni palekana ʻole ma nā wahi o ka ʻeleʻele a me ka pulupulu, e hiki ai ke hoʻohaʻahaʻa maʻalahi i nā ʻāpana palaki a me nā ʻāpana me ka pilikia ʻole o ka ʻili.
Ma muli o kona hoʻolaha nui ʻana, Hāʻawi ka emulsion i ka uhi ʻinikua like ʻole ma nā geometries paʻakikī, ʻoi aku ma mua o ka hoʻokuʻu ʻana i ka wax kuʻuna a i ʻole silicone.
Eia kekahi, ʻaʻole like me nā ʻelele ʻaila mineral, ʻAʻole neʻe nui ka zinc stearate a i ʻole e hoʻoweliweli i ka paʻa pena, kūpono ia no ka hana kaʻa a me nā mea kūʻai aku.
2.2 Pale wai, Anti-Caking, a me ka hoʻololi ʻana o ka ʻili
Lubrication i hala, ʻO ke ʻano hydrophobic o ka zinc stearate e hāʻawi i ka pale wai i nā papa, lole lole, a me nā mea hana ke hoʻohana ʻia e ka hoʻonā.
Ma ka maloʻo ʻana a i ʻole ka hoʻōla ʻana, hoʻohui ʻia nā nanoparticles a hoʻonohonoho i ko lākou mau kaulahao alkyl i waho, ka hoʻomohala ʻana i kahi ʻili haʻahaʻa haʻahaʻa e kūʻē i ka pulu a me ka hoʻomaʻamaʻa ʻana.
Hoʻohana ʻia kēia hale noho i ka mālama wai wai no ka pepa, papa puluniu, a me nā huahana sima.
I nā huahana pauka e like me nā toner, nā puaʻa, a me nā lāʻau lapaʻau, ʻO ka ultrafine zinc stearate solution e lawelawe ma ke ʻano he ʻelele anti-caking ma o ka uhi ʻana i nā ʻāpana a me ka hōʻemi ʻana i ka ʻōpala interparticle a me ka puʻu..
Ma hope o ka waiho ʻana a me ka maloʻo, hoʻomohala ia i kahi papa lubricating e hoʻomaikaʻi i ka flowability a mālama i nā ʻano.
Eia kekahi, hiki i ka hoʻonā ke hoʻopilikino i ka ʻano o ka ʻili, ka hāʻawi ʻana i kahi manaʻo palupalu i nā kiʻiʻoniʻoni plastik a me nā ʻili papa– he hiʻohiʻona i waiwai ʻia i ka ʻeke a me nā mea uila uila.
