IiPolyamineszimele udidi lweekhompawundi ze-organic ezibonakaliswa bubukho bamaqela amaninzi e-amino. Ezi khompawundi, ezihlala zingenambala, isisombululo esityebileyo kumanqanaba e-pH angathathi cala. Ngokongeza ii-amine ezahlukeneyo okanye ii-polyamines ngexesha lokuveliswa, iimveliso ze-polyamine ezinobunzima obahlukeneyo beemolekyuli kunye namanqanaba okuhluma zinokufunyanwa ukuze zilungelelanise neendawo ezahlukeneyo zonyango lwamanzi.
Ngoko ke, ukusetyenziswa kwe-polyamines kugubungela amashishini ahlukeneyo, kubandakanya ukucaciswa kwamanzi, ukwahlulwahlulwa kweoyile namanzi, ukususwa kombala, unyango lwenkunkuma, kunye nokujiya kwe-latex kwizityalo zerabha. Ezi khompawundi zikwaluncedo kushishino lokugquma kunye nephepha, kunye nokusetyenziswa okuhlukeneyo okufana nonyango lwenkunkuma yokucubungula inyama, njengakwinkunkuma yezityalo zenkukhu. Ii-polyamines ziyafumaneka kwiindidi ezahlukeneyo, kunye noxinzelelo oluqinileyo oluqala kwi-50 ukuya kwi-60%.
Iipolyamines zibalaseleyo ekudibaniseni i-colloidal dispersions, ngakumbi kwizicelo zolawulo lwedipozithi malunga ne-pulp, i-stock, iingcingo, okanye ii-felts. Zisusa ngokufanelekileyo izinto eziphilayo kunye nombala kwi-recirculating okanye kwi-diffuse streams kwi-pulp nakwi-paper mills. Nangona kunjalo, ukukhetha imveliso ye-polyamine engabizi kakhulu kufuna uvavanyo lokusebenza olulungiselelwe ukutya okanye umjelo othile ojoliswe kunyango. Iipolyamines zinokufakwa nokuba zicocekile okanye zixutywe kumgca kwindawo yonyango.
Iimfuno zomlinganiselo we-polyamines zixhomekeke kubunzima bengxaki ekhoyo. Ukulawula idiphozithi kwi-pulp okanye kwi-stock, idosi idla ngokuba phakathi kwe-0.25 ukuya kwi-2.5 yeekhilogram ze-polyamine ngetoni ye-pulp okanye kwi-stock (isiseko esomileyo). Xa kulungiswa imiba yediphozithi kwilaphu elenzayo, idosi ecetyiswayo iphakathi kwe-0.10 ukuya kwi-1.0 milliliters ngomzuzu ngenyawo lobubanzi belaphu.
Ukugcinwa kunye nokuphathwa kakuhle kweepolyamines kubaluleke kakhulu ukuze zihlale zisebenza kakuhle. Iipolyamines kufuneka zigcinwe kubushushu obuphakathi kwe-10–32°C. Ukuvezwa okwethutyana kumaqondo obushushu angaphandle kolu luhlu akudli ngokulimaza imveliso. Ukuba ikhenkcezisiwe, iipolyamines kufuneka zifudumale ziye kuma-26–37°C kwaye zixutywe kakuhle ngaphambi kokusetyenziswa. Ixesha lokugcinwa kweepolyamines lidla ngokufikelela kwiinyanga ezili-12.
Kwizicelo ezisebenzayo, indibaniselwano yeI-Polyamine FlocculantI-s ene-PAC (i-polyaluminum chloride) ibonakalise ukusebenza kakuhle kokususa i-turbidity kwiinkqubo zonyango lwamanzi. Indibaniselwano ye-PAC/polyamine inciphisa ngempumelelo idosi ye-PAC, yehlisa uxinzelelo lwee-ion ze-aluminium ezisele emanzini acociweyo, kwaye iphucula ukususwa kwe-turbidity.
Ngexesha lokugcina, iipolyamines kufuneka zigcinwe kwizikhongozeli zazo zokuqala ezineempuphu, kude nobushushu, nelanga elithe ngqo. Ukuze ufumane imiyalelo eneenkcukacha zokuphatha kunye namanyathelo okhuseleko, abasebenzisi kufuneka bajonge ilebheli yemveliso kunye nePhepha leDatha yoKhuseleko (SDS).
