Polyamine ua haujlwm li cas?

Polyamine, ib qho tseem ceebcationic polyelectrolyte, ua haujlwm ua tus neeg sawv cev muaj zog hauv ntau yam kev siv vim nws cov yam ntxwv tshwj xeeb thiab cov txheej txheem. Cia peb kawm txog kev ua haujlwm ntawm polyamine thiab tshawb nrhiav nws cov ntawv thov ntau yam.

Cov yam ntxwv thiab kev siv ntawm Polyamines:

Polyamine yog ib homopolymer linear uas muaj cov dej zoo heev thiab sib xws, ua rau nws siv tau ntau yam hauv ntau yam lag luam. Nws qhov ruaj khov ua rau nws tsis cuam tshuam rau qhov sib txawv ntawm pH thiab tiv taus kev puas tsuaj ntawm chlorine, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv. Tsis tas li ntawd, polyamine muaj kev tiv taus kub thiab siab, nrog rau kev tiv taus chlorine lossis kev txiav ceev ceev, ua kom muaj kev ua tau zoo tshaj plaws hauv cov chaw nyuaj.

Ntxiv mus, polyamine tsis muaj tshuaj lom, txawm hais tias nws yuav ua rau khaus rau ntawm daim tawv nqaij thiab qhov muag, qhia txog qhov tseem ceeb ntawm kev tuav thiab kev ceev faj thaum siv nws.

Txoj Haujlwm Ua Haujlwm ntawm Polyamines:

Thaum siv ua flocculant, polyamine ua haujlwm los ntawm lub tshuab uas cuam tshuam nrog electrostatic neutralization thiab adsorption bridging. Qhov ua tau zoo ntawm polyamine ua flocculant sib raug zoo nrog qhov hnyav molecular ntawm cov polymer, qib ntawm cationicity, thiab qib ntawm branching. Qhov hnyav molecular siab dua, cationicity, thiab branching ua rau muaj kev ua tau zoo dua. Ntxiv mus, polyamine qhia txog kev sib koom tes, tshwj xeeb tshaj yog pom tseeb thaum ua ke nrog PAC (polyaluminum chloride), ua rau muaj kev cuam tshuam synergistic thiab kev ua haujlwm zoo dua.

Hauv kev siv ua haujlwm, kev siv thiab koob tshuaj ntawm polyamine zoo ib yam li PA (polyacrylamide) thiab PDADMAC (polydiallyldimethylammonium chloride). Txawm li cas los xij, polyamine muaj qhov ceev ceev dua, qhov hnyav molecular qis dua, cov monomers seem ntau dua, thiab cov yam ntxwv tshwj xeeb piv rau PA thiab PDADMAC.

Polyamine Ua Haujlwm Nrog PAC:

Polyamine muaj txiaj ntsig zoo kawg nkaus hauv kev tshem tawm cov organic matter thiab pigments ntawm cov pulp thiab cov dej rov ua dua lossis cov dej effluent ntawm lub tshuab pulp thiab cov ntawv. Thaum siv ua ke nrog PAC, polyamine txhim kho cov txheej txheem coagulation, ua rau kev tshem tawm turbidity zoo dua thiab txo qhov yuav tsum tau siv PAC. Kev koom tes no qhia txog kev sib koom tes ntawm polyamine thiab PAC hauv kev siv dej kho.

Ntim thiab Khaws Cia:

Feem ntau Polyamine raug ntim rau hauv 210 kg yas nruas lossis 1100 kg IBC (Intermediate Bulk Container). Nws yuav tsum tau khaws cia rau hauv qhov chaw qhuav, muaj cua nkag zoo ntawm chav tsev kub, kom ntseeg tau tias lub sijhawm khaws cia txog li 24 lub hlis.

Xaus lus, polyamine tshwm sim los ua ib qho kev daws teeb meem ntau yam nrog ntau yam kev siv hauv kev kho dej, kev sib cais roj-dej, thiab cov txheej txheem tswj cov khib nyiab. Nws cov yam ntxwv tshwj xeeb thiab kev sib koom tes nrog lwm cov tshuaj ua rau nws yog ib qho cuab yeej tseem ceeb hauv ntau qhov chaw lag luam, pab txhawb kev ua haujlwm zoo dua thiab kev ruaj khov ntawm ib puag ncig.

Peb qhov kev paub tshwj xeeb thiab dav dav hauvkev muab khoom thiab kev siv cov polyaminemuaj txiaj ntsig zoo rau peb cov neeg siv khoom hauv kev txhawb nqa thiab kev txawj ntse hauv kev ua kom cov txheej txheem zoo dua thiab kev lag luam ua haujlwm zoo dua.
