Ama-Polyamine, evame ukufushaniswa ngokuthi i-PA, iyisigaba samakhemikhali e-organic aqukethe amaqembu amaningi ama-amino. Lawa ma-molecule aguquguqukayo athola ukusetshenziswa okubanzi kuzo zonke izimboni ezahlukene, okubaluleke kakhulu emkhakheni wokwelashwa kwamanzi. Amakhemikhali Okwelapha Amanzi Abakhiqizi badlala indima ebalulekile ekusebenziseni izinzuzo zama-polyamine ukuqinisekisa ukuhlanzwa nokuphepha kwemithombo yamanzi.
Ukusetshenziswa okubalulekile kwama-polyamine kusemkhakheni wokwelashwa kwamanzi. Amakhemikhali Okwelapha Amanzi Abakhiqizi basebenzisa ama-polyamine njengama-coagulant nama-flocculant ekuhlanzweni kwamanzi. Ama-polyamine asebenza kahle kakhulu ekususeni ukungcola, izinhlayiya ezilengayo, nezinto ze-colloidal emanzini, ngaleyo ndlela kuthuthukiswe ikhwalithi yawo. Amandla ama-polyamine okwakha ama-complexes anokungcola enza kube lula ukususwa kwawo ngemvula noma ukuhlanganiswa, okuholela emanzini acacile futhi aphephile.
Uma kubhekwa ukwelashwa kwamanzi, ama-polyamine anegalelo ekusebenzeni kahle kwenqubo yokwelapha ngokukhuthaza ukwakheka kwama-floc amakhulu namakhulu. Lokhu kusiza ezigabeni zokuthungwa kanye nokuhlunga, okwenza kube lula ukuhlukanisa ukungcola emanzini.Abakhiqizi Bamakhemikhali Okwelapha AmanziSebenzisa izakhiwo ezihlukile ze-polyamines ukuze uthuthukise izinqubo zokugaya kanye nokuxubana kwamanzi, uqinisekise ukukhiqizwa kwamanzi ahlangabezana nezindinganiso zekhwalithi eziqinile.
Ama-polyamine nawo adlala indima ebalulekile ezimbonini ezihilela ukuqeda insimbi kanye nokufaka i-electroplating. Kulezi zicelo, ama-polyamine asebenza njengezinto eziyinkimbinkimbi ezakha ama-complexes azinzile ngama-ion ensimbi. Lesi sici sibalulekile ekuvimbeleni ukukhukhuleka kwama-hydroxide ensimbi, okungaholela ezinkingeni zokusebenza kanye nokukhathazeka ngemvelo. Amakhemikhali Okwelapha Amanzi Abakhiqizi bafaka ama-polyamine ekwakhiweni kwabo ukuze babhekane nezinselele ezihambisana nokungcola okuqukethe insimbi.
Ngaphezu kwalokho, ama-polyamine athola ukusetshenziswa kwezolimo njengabalawuli bokukhula kwezitshalo. Umthelela wawo omuhle ekuthuthukisweni kwezitshalo, ekuqhakazeni nasekutheleni izithelo uholele ekusetshenzisweni kwawo ekuthuthukiseni isivuno sezitshalo kanye nekhwalithi. Ngokuthonya izinqubo ezahlukahlukene zomzimba ezitshalweni, ama-polyamine anegalelo ekuthuthukiseni ukubekezelela ukucindezeleka kanye nokuqina okuphelele. Abalimi kanye nabasebenzi bezolimo bathembele kuma-polyamine ukuze bathuthukise izimo zokukhula kanye nokukhiqiza kwezitshalo.
I-PAzisebenza njengenhlanganisela eguquguqukayo enezicelo ezihlanganisa ukwelashwa kwamanzi, ukuqeda insimbi, kanye nezolimo. Indima yazo ekuhlanganiseni, ukugoqa, kanye nokwakheka okuyinkimbinkimbi izenza zibe usizo kakhulu kubakhiqizi bamakhemikhali okwelapha amanzi, zinegalelo ekukhiqizweni kwamanzi ahlanzekile naphephile. Ukusetshenziswa okuhlukahlukene kwama-polyamine kugcizelela ukubaluleka kwazo ekubhekaneni nezinselele ezimbonini ezahlukahlukene, okubonisa amandla azo okuhlola okuqhubekayo kanye nokusungula izinto ezintsha.
