1. Hoʻohana nui ʻia i nā mea kōkua o ke kahua ʻaila, ka mālama ʻana i ka wai ʻino, ka paʻi ʻana a me ka hoʻoluʻu ʻana, ka hana pepa, ka ʻoihana kemika o kēlā me kēia lā, ka lāʻau lapaʻau, ka lole, ka ʻili a me nā ʻoihana ʻē aʻe.
2. Hoʻohana ʻia ka monomer DADMAC i ka mālama wai, ʻoihana pepa, ʻoihana paʻi a me ka hoʻoluʻu ʻana, synthesis resin, a pēlā aku
3. ʻO nā hui i hiki ke hana ʻia ma lalo o nā kūlana PH like ʻole he kūpaʻa paʻakai maikaʻi loa a me ke kūpaʻa alkali; Hoʻohana ʻia ʻo Diallyldimethylammonium Chloride no ka polymerization o nā mea hoʻomaka radical manuahi (e like me nā peroxides a me nā hui azo); Hiki ke homopolymerized a copolymerized paha ka monomer cationic me nā monomers vinyl ʻē aʻe e hoʻolauna i ka hui ammonium quaternary i loko o ka polymer, no laila he polarity ikaika a me ka pilina no nā mea anionic.
1. Nā hui polymer hana nui: Loaʻa i ka molekole Diallyldimethylammonium chloride ʻelua mau pilina pālua allyl (-CH=CH₂), nona ka hana polymerization radical free ikaika a hiki ke hoʻokō koke i ka homopolymerization (hana ʻana i ka PDADMAC) a i ʻole copolymerization me nā monomers e like me ka acrylamide a me ka acrylic acid. He akahai nā kūlana polymerization (hiki ke hana i ka hopena ma ka mahana maʻamau a me ke kaomi). ʻAʻole pono ia i nā kaʻina hana paʻakikī a kūpono no ka hana ʻoihana nui.
2. Ka nui o ka hoʻouka cation ikaika: ʻO ka hui paʻakai ammonium quaternary (-n ⁺(CH₃)₂-) he hoʻouka maikaʻi mau loa a he nui ka nui o ka hoʻouka (ʻoi aku ke kiʻekiʻe ma mua o nā monomers cationic maʻamau). Loaʻa i ka Diallyl dimethyl ammonium chloride kahi hiki ke hoʻohuihui a me ka neutralization ikaika loa me nā mea anionic (e like me nā ʻāpana i hoʻokuʻu ʻia i loko o ka wai hoʻoneoneo, nā olonā pulp, a me nā wahi hoʻouka maikaʻi ʻole ma luna o nā pōhaku waihona aila). Loaʻa iā ia kahi pono kiʻekiʻe.
3. Paʻa kemika maikaʻi loa: ʻAʻole hiki ke pala ka monomer DADMAC i ka wā e mālama ʻia ai i ka mahana o ka lumi, he ākea ka pale ʻana o ka waikawa a me ka alkali (paʻa i loko o ka pH 2-11), ʻaʻole maʻalahi ka oxidized a i ʻole ka hoʻemi ʻia, a he kūpono maikaʻi me nā mea hoʻohui kemika ʻē aʻe (e like me nā flocculants a me nā mea hoʻohuihui mea hoʻoneʻe aila) me ka ʻole o nā hopena maikaʻi ʻole.
4. Ka wai hoʻoheheʻe ikaika loa: Hiki ke hui pū ʻia ka CAS 7398-69-8 DADMAC me ka wai ma kekahi ʻano. Loaʻa i ka wai ka transparency kiʻekiʻe, ʻaʻohe ua a stratification paha, a kūpono no ka dilution ma hope, hoʻohui a i ʻole nā hopena polymerization me ka ʻole o ka pono e hoʻohui i nā mea hoʻoheheʻe organik hou (e hōʻemi ana i ke kaomi a me nā kumukūʻai o ke kaiapuni).
Pahu 200L/Pahu IBC a i ʻole ke koi a nā mea kūʻai aku. E mālama iā Diallyl Dimethyl Ammonium Chloride mai ka mālamalama ma ka mahana ma lalo o 25 ℃.
