Zithini iiPolyamines?

IiPolyamines, edla ngokufinyezwa njenge-PA, ludidi lweekhompawundi ze-organic eziqulathe amaqela amaninzi e-amino. Ezi molekyuli zisebenziseka lula zifumana uluhlu olubanzi lwezicelo kumashishini ahlukeneyo, kwaye zibalulekile kakhulu kwicandelo lokunyanga amanzi. Abavelisi beekhemikhali zokunyanga amanzi badlala indima ebalulekileyo ekusebenziseni iingenelo ze-polyamines ukuqinisekisa ukucocwa nokhuseleko lwezixhobo zamanzi.

Enye indlela ebalulekileyo yokusebenzisa iipolyamines kukusebenza kwamanzi. Iikhemikhali zokunyanga amanzi Abavelisi basebenzisa iipolyamines njengee-coagulants kunye nee-flocculants ekucoceni amanzi. Iipolyamines zisebenza kakuhle ekususeni ukungcola, amasuntswana axhonyiweyo, kunye nezinto ze-colloidal emanzini, ngaloo ndlela ziphucula umgangatho wawo. Amandla eepolyamines okwenza ii-complexes ezinezingcolisi enza kube lula ukususwa kwazo ngemvula okanye ukuhlanganiswa, nto leyo ekhokelela kumanzi acacileyo nakhuselekileyo.

Kwimeko yokunyanga amanzi, iipolyamines zinegalelo ekusebenzeni kakuhle kwenkqubo yokunyanga ngokukhuthaza ukwakheka kwee-flocs ezinkulu nezixineneyo. Oku kunceda kwizigaba zokubola kunye nokuhluzwa, okwenza kube lula ukwahlula ukungcola emanzini.Abavelisi beekhemikhali zokucoca amanziSebenzisa iipropati ezikhethekileyo ze-polyamines ukuphucula iinkqubo zokujiya kunye nokuqunjelwa, ukuqinisekisa ukuveliswa kwamanzi ahlangabezana nemigangatho yomgangatho ongqongqo.

Iipolyamines zikwadlala indima ebalulekileyo kumashishini aquka ukugqitywa kwesinyithi kunye nokufakelwa kwe-electroplating. Kwezi zicelo, iipolyamines zisebenza njengee-complexing agents ezenza ii-complexes ezizinzileyo ezinee-ion zesinyithi. Le propati ibalulekile ekuthinteleni ukuna kwe-hydroxides zesinyithi, nto leyo enokubangela imiba yokusebenza kunye neenkxalabo zokusingqongileyo. Abavelisi beekhemikhali zokucoca amanzi bafaka iipolyamines kwiifomyula zabo ukujongana nemingeni enxulumene nokungcola okunesinyithi.

Ukongeza, iipolyamines zifumana ukusetyenziswa kwezolimo njengabalawuli bokukhula kwezityalo. Impembelelo yazo entle ekuphuhlisweni kwezityalo, ekudubuleni, nasekuveliseni iziqhamo ikhokelele ekusetyenzisweni kwazo ekuphuculeni isivuno sezityalo kunye nomgangatho. Ngokuphembelela iinkqubo ezahlukeneyo ze-physiological kwizityalo, iipolyamines zinegalelo ekuphuculeni ukunyamezela uxinzelelo kunye nokuqina ngokubanzi. Abalimi kunye nabasebenzi bezolimo baxhomekeke kwiipolyamines ukuphucula iimeko zokukhula kunye nemveliso yezityalo.

I-PAzisebenza njengekhompawundi enokusebenziseka ngeendlela ezahlukeneyo enezicelo eziquka unyango lwamanzi, ukugqitywa kwesinyithi, kunye nezolimo. Indima yazo ekudibaniseni, ukuqunjelwa, kunye nokwakheka okuntsonkothileyo kuzenza zibe luncedo kakhulu kubavelisi beekhemikhali zoNyango lwaManzi, zinegalelo kwimveliso yamanzi acocekileyo nakhuselekileyo. Ukusetyenziswa okwahlukeneyo kwe-polyamines kugxininisa ukubaluleka kwazo ekusombululeni imingeni kumashishini ahlukeneyo, kubonisa amandla azo okuqhubeka nophando kunye nokuvelisa izinto ezintsha.
