Diallyldimethylammonium Chloride DADMAC Cas 7398-69-8
Diallyldimethylammonium chloride (CAS 7398-69-8) imagwiritsidwa ntchito kwambiri m'mafakitale othandizira mafuta, kukonza zimbudzi, kusindikiza ndi kupaka utoto, kupanga mapepala, makampani opanga mankhwala tsiku ndi tsiku, mankhwala, nsalu, zikopa ndi mafakitale ena.

1. Amagwiritsidwa ntchito kwambiri m'mafakitale othandizira mafuta, kukonza zimbudzi, kusindikiza ndi kupaka utoto, kupanga mapepala, makampani opanga mankhwala tsiku ndi tsiku, mankhwala, nsalu, zikopa ndi mafakitale ena.
2. DADMAC monomer yomwe imagwiritsidwa ntchito pochiza madzi, makampani opanga mapepala, makampani osindikiza ndi kupaka utoto, kupanga utomoni, ndi zina zotero
3. Mankhwala omwe angapangidwe pansi pa mikhalidwe yosiyanasiyana ya PH ali ndi kukana kwabwino kwa mchere komanso kukana kwa alkali; Diallyldimethylammonium Chloride yomwe imagwiritsidwa ntchito popolisha ma free radical oyambitsa (monga peroxides ndi azo compounds); Cationic monomer ikhoza kupolimitsidwa kapena kupolimitsidwa ndi ma vinyl monomers ena kuti ilowetse gulu la quaternary ammonium mu polima, kotero imakhala ndi polarity yamphamvu komanso kuyanjana kwa zinthu za anionic.
1. Magulu a polima omwe amagwira ntchito kwambiri: Molekyulu ya Diallyldimethylammonium chloride ili ndi ma bond awiri a allyl double (-CH=CH₂), yomwe ili ndi mphamvu yamphamvu ya polymerization ya free radical ndipo imatha kupanga homopolymerization mwachangu (kupanga PDADMAC) kapena copolymerization ndi ma monomers monga acrylamide ndi acrylic acid. Mikhalidwe ya polymerization ndi yofatsa (kuchitapo kanthu kumatha kuchitika kutentha kwabwinobwino ndi kupanikizika). Sikufuna njira zovuta ndipo ndi yoyenera kupanga mafakitale akuluakulu.
2. Kuchuluka kwa mphamvu ya cation: Gulu la mchere wa quaternary ammonium (-n ⁺(CH₃)₂-) limakhala ndi mphamvu yokhazikika ya positive ndipo lili ndi mphamvu yayikulu ya cationic (yokwera kwambiri kuposa ya ma monomers wamba a cationic). Diallyl dimethyl ammonium chloride ili ndi mphamvu yamphamvu kwambiri ya adsorption ndi neutralization ndi zinthu za anionic (monga tinthu tomwe timapachikidwa m'madzi otayira, ulusi wa pulp, ndi malo opanda mphamvu pamwamba pa miyala yosungiramo mafuta). Ili ndi mphamvu yayikulu.
3. Kukhazikika kwabwino kwa mankhwala: DADMAC monomer siiwonongeka ikasungidwa kutentha kwa chipinda, imakhala ndi mitundu yosiyanasiyana ya asidi ndi alkali resistance (yokhazikika mkati mwa pH 2-11), siisungunuka mosavuta kapena kuchepetsedwa, ndipo imagwirizana bwino ndi zina zowonjezera mankhwala (monga flocculants ndi zigawo zamafuta osunthika) popanda zotsatirapo zilizonse zoyipa.
4. Kusungunuka kwa madzi mwamphamvu kwambiri: CAS 7398-69-8 DADMAC ikhoza kusakanikirana ndi madzi molingana ndi momwe zilili. Yankho lamadzi lili ndi mawonekedwe owonekera bwino, palibe mvula kapena kugawikana, ndipo ndi losavuta kusungunuka, kuwonjezera kapena kupopera popanda kufunikira kuwonjezera zosungunulira zina zachilengedwe (kuchepetsa kupsinjika kwa chilengedwe ndi ndalama).
Drum ya 200L/IBC kapena zomwe makasitomala akufuna. Sungani Diallyl Dimethyl Ammonium Chloride kutali ndi kuwala pa kutentha kosakwana 25℃.
