Polyaminessawv cev rau ib chav kawm ntawm cov organic tebchaw uas muaj nyob ntawm ntau pawg amino. Cov tebchaw no, uas feem ntau tsis muaj xim, cov tshuaj tuab ntawm ze li nruab nrab pH theem. Los ntawm kev ntxiv cov amines sib txawv los yog polyamines thaum lub sij hawm tsim khoom, polyamine cov khoom uas muaj qhov sib txawv molecular hnyav thiab qib ntawm cov ceg tuaj yeem tau txais los hloov kho rau cov dej sib txawv.
Yog li ntawd, cov ntawv thov ntawm polyamines nthuav dav ntau yam kev lag luam, suav nrog kev qhia dej, kev sib cais roj-dej, kev tshem tawm xim, kev kho cov khib nyiab, thiab latex coagulation hauv cov nroj tsuag roj hmab. Cov tebchaw no kuj pom muaj txiaj ntsig hauv cov txheej txheej thiab ntawv kev lag luam, nrog rau kev siv ntau yam xws li cov nqaij ua cov khoom pov tseg, xws li hauv cov nqaij qaib cog pov tseg. Polyamines muaj nyob rau hauv ntau qib, nrog rau cov concentration ntawm 50 mus rau 60%.
Polyamines ua tau zoo hauv coagulating colloidal dispersions, tshwj xeeb tshaj yog nyob rau hauv kev tswj kev tso nyiaj rau cov ntaub ntawv, cov khoom, cov xov hlau, los yog cov ntaub. Lawv zoo tshem tawm cov organics thiab xim los ntawm recirculating los yog kwj dej nyob rau hauv pulp thiab ntawv mills. Txawm li cas los xij, xaiv cov khoom lag luam polyamine tus nqi zoo tshaj plaws yuav tsum muaj kev ntsuas kev ua tau zoo raws li cov khoom noj tshwj xeeb lossis cov kwj dej npaj rau kev kho mob. Polyamines tuaj yeem siv tau zoo los yog diluted hauv kab ntawm qhov kev kho mob.
Kev noj tshuaj rau polyamines nyob ntawm qhov hnyav ntawm qhov teeb meem ntawm tes. Rau kev tswj kev tso nyiaj hauv cov ntaub so ntswg lossis cov khoom lag luam, qhov ntau npaum li cas ntawm 0.25 mus rau 2.5 kilograms ntawm polyamine ib tuj ntawm pulp lossis Tshuag (qhuav hauv paus). Thaum hais txog cov teeb meem kev tso nyiaj ntawm cov ntaub ntawv, qhov pom zoo ntau npaum li cas ntawm 0.10 mus rau 1.0 milliliters ib feeb ib ko taw ntawm cov ntaub dav.
Kev khaws cia kom zoo thiab tuav cov polyamines yog qhov tseem ceeb los tswj lawv cov kev ua tau zoo. Polyamines yuav tsum muab cia rau hauv qhov kub ntawm 10-32 ° C. Lub sij hawm luv luv rau qhov kub thiab txias sab nraum qhov no feem ntau tsis ua mob rau cov khoom. Yog tias khov, polyamines yuav tsum tau sov rau 26-37 ° C thiab sib tov kom huv si ua ntej siv. Lub txee lub neej ntawm polyamines feem ntau txuas mus rau 12 lub hlis.
Hauv kev siv tswv yim, kev sib xyaw ua ke ntawmPolyamine Flocculants nrog PAC (polyaluminum chloride) tau ua kom pom kev txhim kho turbidity tshem tawm efficiency hauv cov txheej txheem dej. PAC / polyamine ua ke ua tau zoo txo PAC ntau npaum li cas, txo qis aluminium ion concentration hauv dej kho, thiab txhim kho turbidity tshem tawm.
Thaum lub sij hawm cia, polyamines yuav tsum tau khaws cia rau hauv lawv cov vented ntim, deb ntawm tshav kub, ncaj qha tshav ntuj. Rau cov lus qhia ntxaws txog kev tuav thiab kev ceev faj txog kev nyab xeeb, cov neeg siv yuav tsum xa mus rau cov khoom lag luam thiab Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS).
