Polyamine PA (EPI-DMA)
Ib pawg polyamine yog cov organic sib xyaw muaj ntau tshaj ob cov amino pab pawg. Alkyl polyamines tshwm sim ib txwm muaj, tab sis ib co yog cov khoom siv hluavtaws. Alkylpolyamines yog xim tsis muaj kob, hygroscopic, thiab dej-soluble. Ze rau ze rau nruab nrab pH, lawv muaj nyob ua ammonium derivatives.
Polyamine yog cov kua cationic polymer ntawm cov nyom molecular uas ua haujlwm sib cais ua cov txheej txheem ua ntej hauv cov txheej txheem sib cais ua ntau yam kev lag luam. Nws tau siv dav siv rau hauv kev tsim cov khoom lag luam ntawm ntau hom kev lag luam kev lag luam thiab dej phwj tuaj.

PA yog ntim rau hauv cov nruas yas
PA yuav tsum tau muab khi thiab muab cia rau hauv qhov chaw qhuav thiab txias. Nws yog tsis muaj zog, tsis muaj nplaim taws thiab tsis muaj txiaj ntsig. Nws tsis yog cov tshuaj txaus ntshai.
Thaum siv los kho cov dej sib txawv lossis dej khib nyiab, qhov ntau npaum li cas yog nyob ntawm qhov kev ua kom nruj thiab cov dej. Qhov kev lag luam ntau tshaj plaws yog raws li kev sim siab. Cov tshuaj pleev qhov chaw thiab cov kev sib xyaw ua ke yuav tsum tau ua tib zoo txiav txim siab tau tias cov tshuaj muaj peev xwm sib xyaw nrog lwm yam tshuaj noj hauv dej thiab cov flocs tsis tuaj yeem tawg. Nws yog qhov zoo dua rau koob tshuaj cov khoom tsis tu ncua.
1. Thaum siv nyob ib leeg, nws yuav tsum tau diluted rau ib co siab ntawm 0.05% -0.5%-raws cov ntsiab lus).
2. Thaum siv los kho cov dej sib txawv ntawm cov dej lossis dej khib nyiab, cov tshuaj noj yog ua raws li cov dej tsis muaj zog thiab cov pa ntawm cov dej. Qhov kev lag luam ntau tshaj plaws yog raws li kev sim siab. Cov tshuaj pleev qhov chaw thiab cov kev sib xyaw ua ke yuav tsum tau ua tib zoo txiav txim siab tau tias cov tshuaj muaj peev xwm sib xyaw nrog lwm yam tshuaj noj hauv dej thiab cov flocs tsis tuaj yeem tawg.
3. Nws yog qhov zoo dua rau koob tshuaj cov khoom tsis tu ncua.
