Nā Polyamineshōʻike i kahi papa o nā hui organik i hōʻike ʻia e ke alo o nā hui amino he nui. ʻO kēia mau hui, he ʻano kala ʻole, he hopena mānoanoa ma kahi kokoke i nā pae pH kūlike. Ma ka hoʻohui ʻana i nā amines a i ʻole polyamines like ʻole i ka wā o ka hana ʻana, hiki ke loaʻa nā huahana polyamine me nā kaumaha molekala like ʻole a me nā kekelē o ka lālā e hoʻololi i nā kahua mālama wai like ʻole.
No laila, ʻo nā noi o nā polyamines e uhi ana i nā ʻoihana like ʻole, me ka hoʻomaʻemaʻe wai, ka hoʻokaʻawale ʻana i ka wai-ʻaila, ka wehe ʻana i ke kala, ka mālama ʻana i nā ʻōpala, a me ka hoʻopili ʻana o ka latex i nā mea kanu laholio. Loaʻa pū kēia mau hui i ka pono i ka ʻoihana uhi a me ka pepa, a me nā noi like ʻole e like me ka mālama ʻana i nā ʻōpala hana ʻiʻo, e like me ka ʻōpala mea kanu moa. Loaʻa nā Polyamines i nā papa he nui, me nā ʻano paʻa mai 50 a 60%.
ʻOi aku ka maikaʻi o nā Polyamines i ka hoʻopili ʻana i nā hoʻolaha colloidal, ʻoi aku hoʻi i nā noi kaohi waiho e pili ana i ka pulp, stock, wires, a i ʻole felts. Hoʻopau maikaʻi lākou i nā mea ola a me ke kala mai nā kahawai recirculating a i ʻole effluent i loko o nā hale wili pulp a me ka pepa. Eia nō naʻe, ʻo ke koho ʻana i ka huahana polyamine kūpono loa e pono ai kahi loiloi hana i hoʻopilikino ʻia i ka hānai kikoʻī a i ʻole ke kahawai i manaʻo ʻia no ka mālama ʻana. Hiki ke lawelawe ʻia nā Polyamines maʻemaʻe a i ʻole diluted in-line ma kahi o ka mālama ʻana.
ʻO nā koi o ka nui no nā polyamines e pili ana i ke koʻikoʻi o ka pilikia e kū nei. No ka kaohi ʻana i ka waiho ʻana i loko o ka pulp a i ʻole ka waihona, ʻo ka nui maʻamau mai 0.25 a 2.5 kilokani o ka polyamine no kēlā me kēia tona o ka pulp a i ʻole ka waihona (ma ke kumu maloʻo). I ka hoʻoponopono ʻana i nā pilikia waiho ʻana ma ka lole hana, ʻo ka nui i ʻōlelo ʻia mai 0.10 a 1.0 milliliters i kēlā me kēia minuke no kēlā me kēia kapuaʻi o ka laulā o ka lole.
ʻO ka mālama pono ʻana a me ka lawelawe ʻana i nā polyamines he mea nui ia e mālama i ko lākou pono. Pono e mālama ʻia nā polyamines i loko o ka pae mahana o 10-32°C. ʻO ka ʻike pōkole ʻana i nā mahana ma waho o kēia pae, ʻaʻole ia e hōʻino i ka huahana. Inā hoʻopaʻahau ʻia, pono e hoʻomehana ʻia nā polyamines i 26-37°C a kāwili maikaʻi ʻia ma mua o ka hoʻohana ʻana. ʻO ka lōʻihi o ke ola o nā polyamines he 12 mau mahina.
Ma nā hana maoli, ʻo ka hui pū ʻana oMea hoʻoheheʻe polyamineUa hōʻike ʻo s me PAC (polyaluminum chloride) i ka hoʻonui ʻia ʻana o ka pono o ka wehe ʻana i ka turbidity i nā kaʻina hana mālama wai. ʻO ka hui pū ʻana o PAC/polyamine e hōʻemi pono ana i ka nui o ka PAC, hoʻohaʻahaʻa i ke koena o ka ion alumini i loko o ka wai i mālama ʻia, a hoʻomaikaʻi i ka wehe ʻana i ka turbidity.
I ka wā e mālama ai, pono e mālama ʻia nā polyamines i loko o kā lākou mau pahu puka mua, kahi e pale aku ai i ka wela a me ka lā pololei. No nā ʻōlelo kuhikuhi kikoʻī no ka lawelawe ʻana a me nā hana palekana, pono nā mea hoʻohana e nānā i ka lepili huahana a me ka Palapala ʻIkepili Palekana (SDS).
ʻO mākou ka poʻe loeamea hoʻolako o nā polyaminesno ka mālama ʻana i ka ʻoihana. Hiki i ka Polyamine no ke kūʻai aku ma kā mākou hui ke hana nui no ka manawa lōʻihi! E leka uila mai iā mākou! (Leka uila:sales@yuncangchemical.com )
