Polyamine PA
Polyamine yog ib qho organic compound uas muaj ntau tshaj ob pawg amino.Alkyl polyamines tshwm sim lawm, tab sis qee qhov yog hluavtaws.Alkylpolyamines tsis muaj xim, hygroscopic, thiab dej-soluble.Nyob ze nruab nrab pH, lawv muaj nyob ua ammonium derivatives.
Polyamine yog cov kua cationic polymer ntawm qhov sib txawv ntawm qhov hnyav molecular uas ua haujlwm tau zoo raws li thawj coagulant thiab them tus neeg sawv cev nruab nrab hauv cov txheej txheem sib cais ua kua hauv ntau yam kev lag luam.Nws tau siv dav hauv kev tsim khoom ntawm ntau hom kev lag luam thiab kev kho dej phwj tuaj.

PA yog ntim rau hauv lub nruas yas
PA yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw qhuav thiab txias.Nws yog tsis muaj mob, tsis muaj-flammable thiab non-explosive.Nws tsis yog tshuaj lom neeg txaus ntshai.
Thaum siv los kho cov dej sib txawv lossis cov dej khib nyiab, qhov ntau npaum li cas yog nyob ntawm qhov turbidity thiab qhov concentration ntawm cov dej.Kev noj nyiaj txiag tshaj plaws yog nyob ntawm qhov kev sim.Qhov chaw txhaj tshuaj thiab qhov sib tov sib xyaw yuav tsum tau ua tib zoo txiav txim siab los lav tias cov tshuaj tuaj yeem sib xyaw nrog lwm cov tshuaj hauv dej thiab cov flocs tsis tuaj yeem tawg.Nws yog qhov zoo dua los txhaj cov khoom tsis tu ncua.
1. Thaum siv ib leeg, nws yuav tsum tau diluted mus rau ib qho concentration ntawm 0.05% -0.5% (raws li cov ntsiab lus khoom).
2. Thaum siv los kho qhov sib txawv ntawm cov dej los yog cov dej khib nyiab, qhov ntau npaum li cas yog nyob ntawm qhov turbidity thiab qhov concentration ntawm cov dej.Kev noj nyiaj txiag tshaj plaws yog nyob ntawm qhov kev sim.Qhov chaw txhaj tshuaj thiab qhov sib tov sib xyaw yuav tsum tau ua tib zoo txiav txim siab los lav tias cov tshuaj tuaj yeem sib xyaw nrog lwm cov tshuaj hauv dej thiab cov flocs tsis tuaj yeem tawg.
3. Nws yog qhov zoo dua los txhaj cov khoom tsis tu ncua.
