1. Siv dav hauv cov chaw pabcuam roj av, kev kho dej phwj tuaj, luam ntawv thiab zas xim, ua ntawv, kev lag luam tshuaj txhua hnub, tshuaj, textile, tawv thiab lwm yam lag luam.
2. DADMAC monomer siv rau hauv kev kho dej, kev lag luam ntawv, kev luam ntawv thiab kev lag luam dyeing, resin synthesis, thiab lwm yam
3. Cov tshuaj uas tuaj yeem ua tau nyob rau hauv ntau yam PH mob muaj kev tiv thaiv ntsev zoo heev thiab tiv thaiv alkali; Diallyldimethylammonium Chloride siv rau polymerization ntawm cov neeg pib dawb radical (xws li peroxides thiab azo compounds); Cationic monomer tuaj yeem homopolymerized lossis copolymerized nrog lwm cov vinyl monomers los qhia quaternary ammonium pawg rau hauv polymer, yog li nws muaj polarity muaj zog thiab affinity rau cov tshuaj anionic.
1. Cov pawg polymer uas muaj zog heev: Cov molecule Diallyldimethylammonium chloride muaj ob lub allyl ob chav bonds (-CH = CH₂), uas muaj cov haujlwm polymerization dawb radical muaj zog thiab tuaj yeem ua tiav homopolymerization (tsim PDADMAC) lossis copolymerization nrog monomers xws li acrylamide thiab acrylic acid sai. Cov xwm txheej polymerization yog qhov tsis hnyav (kev ua haujlwm tuaj yeem tshwm sim ntawm qhov kub thiab txias ib txwm muaj). Nws tsis xav tau cov txheej txheem nyuaj thiab tsim nyog rau kev tsim khoom lag luam loj.
2. Muaj zog cation charge density: Cov ntsev ammonium quaternary (-n⁺(CH₃)₂-) nqa ib qho zoo tas mus li thiab muaj qhov ceev charge siab (ntau dua li ntawm cov cationic monomers ib txwm muaj). Diallyl dimethyl ammonium chloride muaj peev xwm adsorption thiab neutralization muaj zog heev nrog cov tshuaj anionic (xws li cov khoom me me hauv cov dej khib nyiab, cov fibers pulp, thiab cov chaw tsis zoo ntawm cov pob zeb roj). Nws muaj kev ua haujlwm zoo.
3. Kev ruaj khov tshuaj zoo heev: DADMAC monomer tsis yooj yim rau kev lwj thaum khaws cia rau hauv chav tsev kub, muaj ntau yam kua qaub thiab alkali tsis kam (ruaj khov hauv pH 2-11), tsis yooj yim oxidized lossis txo qis, thiab muaj kev sib raug zoo nrog lwm cov tshuaj ntxiv (xws li flocculants thiab cov roj hloov chaw tus neeg sawv cev) tsis muaj kev tsis zoo.
4. Kev yaj dej muaj zog heev: CAS 7398-69-8 DADMAC tuaj yeem sib xyaw nrog dej hauv txhua qhov sib piv. Cov kua dej muaj pob tshab siab, tsis muaj nag lossis stratification, thiab yooj yim rau kev dilution, ntxiv lossis polymerization reactions tom qab tsis tas yuav ntxiv cov organic solvents ntxiv (txo qhov kev nyuaj siab thiab cov nqi ib puag ncig).
200L nruas/IBC nruas lossis qhov yuav tsum tau ua ntawm cov neeg siv khoom. Khaws Diallyl Dimethyl Ammonium Chloride kom deb ntawm lub teeb ntawm qhov kub hauv qab 25 ℃.
