Polyamine ua haujlwm li cas?

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

Cov yam ntxwv thiab kev siv ntawm Polyamines:

Polyamine yog homopolymer linear uas muaj cov dej solubility zoo heev thiab kev sib raug zoo, ua rau nws muaj ntau yam thoob plaws kev lag luam sib txawv. Nws qhov xwm txheej ruaj khov ua rau nws tsis hnov ​​​​tsw rau pH hloov pauv thiab tiv taus cov tshuaj chlorine degradation, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv. Tsis tas li ntawd, polyamine nthuav tawm qhov kub thiab txias tsis kam, nrog rau kev ua haujlwm siab rau cov tshuaj chlorine lossis kev kub ceev shear, kom ntseeg tau tias kev ua haujlwm zoo hauv qhov xav tau ib puag ncig.

Tsis tas li ntawd, polyamine tsis muaj tshuaj lom, txawm hais tias nws yuav ua rau khaus ntawm daim tawv nqaij thiab qhov muag, hais txog qhov tseem ceeb ntawm kev tuav kom raug thiab ceev faj txog kev nyab xeeb thaum siv.

Ua hauj lwm Mechanism ntawm Polyamines:

Thaum ua hauj lwm raws li ib tug flocculant, polyamine ua hauj lwm los ntawm ib tug mechanism uas muaj electrostatic neutralization thiab adsorption bridging. Kev ua tau zoo ntawm polyamine raws li flocculant cuam tshuam nrog qhov hnyav molecular ntawm cov polymer, qib ntawm cationicity, thiab degree ntawm branching. Siab molecular hnyav, cationicity, thiab branching ua rau superior kev ua tau zoo. Tsis tas li ntawd, polyamine nthuav tawm kev sib koom tes muaj peev xwm, tshwj xeeb tshaj yog tshwm sim thaum ua ke nrog PAC (polyaluminum chloride), uas ua rau muaj kev sib koom ua ke thiab txhim kho kev ua haujlwm zoo.

Hauv kev siv cov tswv yim, kev siv thiab ntau npaum li cas ntawm polyamine yog zoo li cov PA (polyacrylamide) thiab PDADMAC (polydiallyldimethylammonium chloride). Txawm li cas los xij, polyamine muaj cov nqi ntau dua, qhov hnyav dua molecular, ntau dua cov monomers, thiab cov yam ntxwv tshwj xeeb piv rau PA thiab PDADMAC.

Polyamine hauv kev koom tes nrog PAC:

Polyamine nthuav tawm cov txiaj ntsig zoo tshaj plaws hauv kev tshem tawm cov organic teeb meem thiab cov pigments los ntawm cov ntaub so ntswg thiab cov ntawv zeb recirculating los yog cov dej effluent. Thaum siv ua ke nrog PAC, polyamine txhim kho cov txheej txheem coagulation, uas ua rau kev txhim kho turbidity tshem tawm thiab txo cov kev xav tau ntawm PAC. Qhov kev sib koom tes no qhia txog kev sib koom ua ke ntawm polyamine thiab PAC hauv cov ntawv thov kev kho dej.

Ntim thiab Cia:

Polyamine feem ntau ntim rau hauv 210 kg yas nruas lossis 1100 kg IBC (Intermediate Bulk Container) tso tsheb hlau luam. Nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated ntawm chav tsev kub, ua kom lub neej txee ntev txog 24 lub hlis.

Hauv kev xaus, polyamine tshwm sim los ua ntau yam kev daws teeb meem nrog ntau yam kev siv hauv kev kho dej, kev sib cais roj-dej, thiab kev tswj cov txheej txheem pov tseg. Nws cov yam ntxwv tshwj xeeb thiab muaj peev xwm sib koom tes nrog lwm cov tebchaw ua rau nws yog ib qho cuab yeej tseem ceeb hauv ntau qhov chaw tsim khoom, pab txhawb kev txhim kho kev ua tau zoo thiab kev ruaj ntseg ib puag ncig.

Peb qhov tshwj xeeb thiab dav kev paub hauv lubkhoom siv thiab siv polyamineyog qhov txiaj ntsig tshwj xeeb rau peb cov neeg siv khoom raws li kev txhawb nqa thiab kev txawj ntse hauv kev txhim kho cov txheej txheem thiab kev lag luam kev lag luam. Yog tias koj xav tau cov khoom no thov hu rau peb.
