Iipolyaminesimele iklasi ye-organic compounds ebonakaliswe kubukho bamaqela amaninzi e-amino. Ezi khompawundi, eziqhelekileyo ezingenambala, isisombululo esityebileyo kumanqanaba asezantsi e-pH. Ngokungongeza i-amines okanye i-polyamines ezahlukeneyo ngexesha lokuvelisa, iimveliso ze-polyamine ezinobunzima obuhlukeneyo be-molecular kunye ne-degrees of branching zingafumaneka ukulungelelanisa kwiindawo ezahlukeneyo zokunyanga amanzi.
Ke ngoko, usetyenziso lweepolyamines luthatha indawo yamashishini ahlukeneyo, kubandakanya ukucaciswa kwamanzi, ukwahlula amanzi e-oyile, ukususwa kombala, ukucocwa kwenkunkuma, kunye ne-latex coagulation kwizityalo zerabha. Ezi khompawundi zikwafumana into eluncedo kwishishini lokugquma kunye nephepha, kunye nakwizinto ezahlukeneyo zokusebenza ezifana nokucocwa kwenkunkuma yokwenziwa kwenyama, njengakwinkunkuma yezityalo zenkukhu. Iipolyamines zifumaneka kumabakala amaninzi, kunye nokugxilwa okuqinileyo ukusuka kwi-50 ukuya kwi-60%.
Iipolyamines zigqwesa ekudibaniseni i-colloidal dispersions, ngakumbi kwizicelo zolawulo lwediphozithi malunga ne-pulp, stock, iingcingo, okanye iifets. Basusa ngokufanelekileyo i-organics kunye nombala kwi-recirculating okanye imilambo emdaka kwi-pulp kunye nephepha lokusila. Nangona kunjalo, ukukhetha eyona mveliso yepolyamine inexabiso eliphantsi kufuna uvandlakanyo lokusebenza olulungiselelwe ukondla okuthile okanye umjelo olungiselelwe unyango. Iipolyamines zinokulawulwa nokuba zicocekile okanye zixutywe emgceni kwindawo yonyango.
Iimfuno zethamo kwiipolyamines zixhomekeke kubunzima bomba okhoyo. Ukulawulwa kwediphozithi kwi-pulp okanye kwi-stock, i-dosage ngokuqhelekileyo isuka kwi-0.25 ukuya kwi-2.5 kilogram ye-polyamine ngetoni ye-pulp okanye i-stock (isiseko esomileyo). Xa ulungisa imiba yediphozithi kwilaphu lokubumba, idosi ecetyiswayo isuka kwi-0.10 ukuya kwi-1.0 milliliters ngomzuzu ngonyawo lobubanzi belaphu.
Ukugcinwa ngokufanelekileyo kunye nokuphathwa kwe-polyamines kubaluleke kakhulu ukugcina ukusebenza kwazo. Iipolyamines kufuneka zigcinwe ngaphakathi kwinqanaba lobushushu le-10-32 ° C. Ukuvezwa kwexesha elifutshane kumaqondo obushushu ngaphandle kolu luhlu ngokuqhelekileyo akuyonzakalisi imveliso. Ukuba iqhwa, i-polyamines kufuneka ifudumale ukuya kwi-26-37 ° C kwaye ixutywe kakuhle ngaphambi kokusetyenziswa. Ubomi beshelufu yeepolyamines buhlala bufikelela kwiinyanga ezili-12.
Kwizicelo eziphathekayo, indibaniselwano yePolyamine Flocculants nge-PAC (i-polyaluminium chloride) ibonise ukususwa kwe-turbidity ephuculweyo kwiinkqubo zokucoca amanzi. I-PAC/polyamine indibaniselwano inciphisa ngokufanelekileyo idosi yePAC, yehlisa intsalela ye-aluminiyam ion concentration kumanzi acociweyo, kwaye iphucula ukususwa kwe-turbidity.
Ngexesha lokugcinwa, i-polyamines kufuneka igcinwe kwimigqomo yabo yokuqala, kude nokushisa, ukukhanya kwelanga. Ukufumana imiyalelo ecacileyo yokuphatha kunye nokukhusela ukhuseleko, abasebenzisi kufuneka babhekisele kwileyibhile yemveliso kunye nePhepha leDatha loKhuseleko (SDS).
Singabantu abaqeqeshiweyoumthengisi weepolyamineskunyango lwamashishini. I-Polyamine ethengiswayo kwinkampani yethu inokusebenza kakhulu ixesha elide! Qhagamshelana nathi! ( imeyile:sales@yuncangchemical.com )
