Ke kūpaʻa wai: Ma ke ʻano he emulsion pale wai, ʻo ke kūpaʻa wai ka mea maʻamau a koʻikoʻi loa. Ma ke ʻano laulā, hiki i nā emulsions me ke kūpaʻa wai maikaʻi ke mālama i ka ʻili pena i moakaka a ʻaʻole maʻalahi ke palupalu ʻoiai ma hope o ka hoʻomoʻa ʻia ʻana i ka wai no ka manawa lōʻihi. Wahi a ka nānā ʻana i ke ʻano kino maʻamau, ʻoi aku ka maikaʻi o ke kūpaʻa wai o ka emulsion kukui polū ma mua o ka emulsion kukui keʻokeʻo waiū a ʻulaʻula paha. Ma ke ʻano laulā, ʻo ka liʻiliʻi o ka nui o ka ʻāpana, ʻoi aku ka maikaʻi o ke kūpaʻa wai, a hiki ke hoʻoholo ʻia ka nui o ka nui o ka ʻāpana e ke ʻano. : Ke kaʻina o ka nui o ka ʻāpana: moakaka > kukui polū > kukui ʻōmaʻomaʻo > kukui ʻulaʻula > keʻokeʻo waiū. l Elongation: ʻO ke kiʻekiʻe o ka elongation, ʻoi aku ka maikaʻi o ka maʻalahi o ka haʻahaʻa o ka mahana, a ʻoi aku ka nui o ka lakio wai-a-pauka. No laila, ʻo ke kiʻekiʻe o ka elongation o ka emulsion e loaʻa kahi kumukūʻai piha maikaʻi.

Hoʻopili: Pono kahi emulsion wai ʻole maikaʻi e loaʻa kahi hopena hoʻopili maikaʻi loa me ke kumu sima. Ma keʻano laulā, ʻo ke ʻano kuʻuna akā ʻoi aku ka maikaʻi, ʻo ia ke kau ʻana i ka emulsion ma kou mau lima, a laila e maloʻo maoli. Ma kekahi ʻaoʻao, ua nānā ʻia ka hopena kaha kiʻi o ka emulsion. Inā paʻakikī ke hamo ma kou mau lima, hōʻike ia he ʻoi aku ka maikaʻi o ka hoʻopili ʻana o ka emulsion. ʻO kekahi ala ʻē aʻe, ʻo ia ke kāwili ʻana i ka emulsion me ka sima, a laila e hana ma luna o ka ʻili o ka tile. , kahi e hōʻike ana he haʻahaʻa ka hoʻopili ʻana o ka emulsion. Inā hui ʻia kahi emulsion maikaʻi me ka sima a hoʻomaloʻo ʻia, ʻaʻole maʻalahi ke pala ʻia.

Palekana kaiapuni: Hana ʻia nā emulsions wai ʻole o ka polymer e ke kaʻina hana polymerization, no laila e pili pololei nā lako holomua a me ke kūpaʻa o ka formula i ka pono o ka synthesis. No nā emulsions me ka pono synthesis haʻahaʻa, e kiʻekiʻe maoli ka nui o ka monomer manuahi, a e kiʻekiʻe maoli ka nui o ka monomer manuahi. He mea ʻawahia. ʻO ke kiʻekiʻe o ka pae, ʻoi aku ka ʻino i ke kino kanaka. Ma keʻano laulā, hiki ke hoʻoholo ʻia ka nui o nā monomers manuahi e ke ʻala. Ma ka ʻaoʻao ʻē aʻe, he maʻalahi ke hana i ke kinoea ammonia ma hope o ka hui ʻana o ka polymer wai ʻole a me ka sima, ʻoiai ʻaʻole ʻino loa ke kinoea ammonia i ke kino kanaka. Eia nō naʻe, inā hana ʻia ke kūkulu ʻana i loko o kahi lumi ʻauʻau pani, hale lua a me nā wahi ʻē aʻe, ma muli o ka ea palupalu ʻole, he maʻalahi ke kumu o ka nui o ke kinoea ammonia ma kēlā me kēia wahi e kiʻekiʻe loa. ʻO ka hana ʻana i ia ʻano no ka manawa lōʻihi e hiki ke alakaʻi maʻalahi i ka wela o ka mucosa ihu.

Ke kūpaʻa ʻana i ke aniau: ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka polymer waterproofing ma mua o ka polyurethane a me ka styrene-butadiene rubber. Maikaʻi ke kūpaʻa ʻana o ka acrylic emulsion i ke aniau, akā ʻoi aku ke kiʻekiʻe o ke kumukūʻai ma mua o ka styrene-acrylic emulsion. ʻO ka ʻokoʻa ma waena o ka styrene-acrylic polymer emulsion a me ka acrylic acid ʻo ia ka ʻokoʻa o ke kūpaʻa melemele, akā i nā mea wai ʻole, hoʻohana pinepine ʻia ka styrene-acrylic polymer Emulsion, kumukūʻai kūpono, kūpaʻa maikaʻi i ke aniau.
