Nā poliaminahōʻike i kahi papa o nā pūhui organik i ʻike ʻia e ka nui o nā pūʻulu amino. ʻO kēia mau pūhui, ʻaʻohe waihoʻoluʻu, ʻano mānoanoa ma kahi kokoke i nā pae pH kū ʻole. Ma ka hoʻohui ʻana i nā amine ʻokoʻa a i ʻole polyamines i ka wā o ka hana ʻana, hiki ke loaʻa nā huahana polyamine me nā paona molekala like ʻole a me nā degere o ka lālā no ka hoʻololi ʻana i nā māla mālama wai like ʻole.
No laila, hoʻohana ʻia nā polyamines i nā ʻoihana like ʻole, e like me ka hoʻomaʻamaʻa wai, ka hoʻokaʻawale ʻana i ka wai aila, ka wehe ʻana i ka waihoʻoluʻu, ka mālama ʻana i ka ʻōpala, a me ka coagulation latex i nā mea kanu lāʻau. Loaʻa kēia mau pūhui i ka pono i loko o ka ʻoihana uhi a me ka pepa, a me nā noi like ʻole e like me ka mālama ʻana i ka ʻiʻo, e like me ka ʻōpala mea kanu moa. Loaʻa nā polyamines i nā māka he nui, me nā ʻano paʻa paʻa mai 50 a 60%.
ʻOi aku ka maikaʻi o nā polyamines i ka coagulating colloidal dispersions, ʻoi aku ka nui ma nā noi mālama waihona e pili ana i ka pulp, stock, wires, a i ʻole felts. Hoʻopau maikaʻi lākou i nā mea kūlohelohe a me ka waihoʻoluʻu mai ka recirculating a i ʻole nā kahawai wai i loko o ka pulp a me ka wili pepa. Eia naʻe, ʻo ke koho ʻana i ka huahana polyamine ʻoi aku ka maikaʻi loa e pono ai kahi loiloi hana i kūpono i ka hānai kikoʻī a i ʻole ke kahawai i manaʻo ʻia no ka mālama ʻana. Hiki ke lawelawe ʻia nā polyamines ma kahi o ka lāʻau maʻemaʻe a hoʻoheheʻe ʻia paha.
ʻO nā koi no nā polyamines e pili ana i ka paʻakikī o ka pilikia ma ka lima. No ka mālama ʻana i ka waihona i loko o ka pulp a i ʻole ka waihona, ʻo ke ʻano maʻamau mai ka 0.25 a i ka 2.5 kilokani o ka polyamine no ke tona o ka pulp a i ʻole ke kumu (ke kumu maloʻo). I ka wā e kamaʻilio ai i nā pilikia waiho kālā ma ka lole hana, ʻo ke ʻano i ʻōlelo ʻia mai ka 0.10 a i ka 1.0 milliliters i kēlā me kēia minuke no ka wāwae o ka laulā lole.
ʻO ka mālama pono a me ka mālama ʻana i nā polyamines ka mea nui e mālama i ko lākou pono. Pono e mālama ʻia nā polyamines i loko o ke ana wela o 10-32°C. ʻAʻole maʻamau ka hoʻopōʻino i ka huahana i ka ʻike pōkole i nā mahana ma waho o kēia pae. Inā maloʻo, pono e hoʻomaʻamaʻa ʻia nā polyamines i 26-37 ° C a hui maikaʻi ʻia ma mua o ka hoʻohana ʻana. ʻO ka lōʻihi o ka mālama ʻana o nā polyamines e hoʻonui i 12 mau mahina.
Ma nā hoʻohana pono, ka hui ʻana oʻO Polyamine Flocculants me PAC (polyaluminum chloride) ua hōʻike i ka hoʻonui ʻana i ka pono hoʻoneʻe turbidity i nā kaʻina hana mālama wai. ʻO ka hui pū ʻana o PAC/polyamine e hōʻemi pono i ka nui o ka PAC, e hoʻohaʻahaʻa i ke koena o ka alumini ion i loko o ka wai i mālama ʻia, a hoʻomaikaʻi i ka wehe ʻana i ka turbidity.
I ka wā o ka mālama ʻana, pono e mālama ʻia nā polyamines i loko o kā lākou mau pahu i hoʻokuʻu ʻia, mai ka wela a me ka lā pololei. No nā ʻōlelo kikoʻī e pili ana i ka mālama ʻana a me ka mālama palekana, pono nā mea hoʻohana e nānā i ka lepili huahana a me ka Pepa ʻIkepili Palekana (SDS).
ʻO mākou ka ʻoihanamea hoʻolako polyamineno ka lapaau hana. ʻO Polyamine no ke kūʻai aku i kā mākou hui hiki ke hana nui no ka manawa lōʻihi! E hui pū me mākou! ( leka uila:sales@yuncangchemical.com )
