Polydadmac. (kana kuti Polydadmac).

Inowanzo shandiswa seflocculant uye dzimwe nguva inosanganiswa nealgicide. Mazita ekutengeserana anosanganisira agequat400, St flocculant, pink cure, cat floc, nezvimwewo. PDMDAAC ine simba rekubatana ne wscp uye poly (2-hydroxypropyl dimethyl ammonium chloride). 413 inowanzo shandiswa se coagulant aid mukurapa mvura mumaindasitiri. Mushure mekuwedzera alum coagulant, chiyero che coagulant chinogona kuponeswa ne30%. Semuenzaniso, mushure mekuwedzera 20 mg / L polyaluminium chloride, wedzera 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride kuti uwedzere kushanda zvakanaka.

Huremu hwePDADMAC hunowanzova pakati pe50000 kusvika 700000, uye simba re dynamic viscosity ye 20% aqueous solution i50-700cps; Huremu hwe molecule yezvigadzirwa zvine polymerization yakakura hunogona kusvika 1000000 kusvika 300000, uye simba re dynamic viscosity i1000-3000 CPS. Simba re intrinsic viscosity i80-300ml / g, uye simba re high viscosity rinogona kusvika 1440ml / g. Chigadzirwa ichi chinowanzova 10-50% solution ine density ye 1.02-1.10 g / ml. Muyero uri mumvura yekunwa unofanirwa kunge uri pasi pe 10mg / L (Taiwan).

Maitiro ekusviba kwemvura yePDMDAAC ane simba guru repolyelectrolyte. Kusviba kwemukati kunoderera nekuwedzera kwehuwandu hwemunyu wakawedzerwa. Kana huwandu hweNaCl hwakakura kupfuura 1 m, kuchinja kwehusviba hwemukati nehuwandu hwemunyu wakawedzerwa kushoma. Kusviba kwemukati kunoyerwa neUbbelohde viscometer mu 1 M NaCl solution pa 30 ℃, uye avhareji yehuremu hwemamorekuru inogona kuwanikwa zvichienderana nefomula.

Huremu hwemamorekuru ePDMDAAC hunogona kuwanikwa kubva mufomura inotevera, umo viscosity yemukati inoyerwa mu 1 M NaCl solution pa 30 ℃: 407.

Huang naReichert vakadzidza nezvekudzikira kwehuremu hwePDMDAAC mukupisa kwakasiyana. Kudzikira kwehuremu kwe53.3-130 ℃ kunokonzerwa nekurasikirwa nemvura; Chengeta zvisina kuchinja pakati pe130-200 ℃; Kudzikira kwehuremu pa200-310 ℃ i41.4%, izvo zvinokonzerwa nekuora kwekupisa. Hapana nzvimbo yekunyunguduka yakawanikwa panguva yese yekupisa. Tembiricha yekuchinja kwegirazi yePDMDAAC ine huremu hwe33 kDa i8 ℃.

PDADMAC haina chepfu yakawanda ku rainbow trout kupfuura chitosan (Waller et al. 1993). Zvisinei, PDADMAC yekuchenesa mvura ine zvirambidzo pahuwandu hwe monomer.

PDMDAAC muChina ine huwandu hwakawanda hwe monomer. PDMDAAC yezvirimwa zviviri zvemakemikari yakaedzwa ndokuwana kuti huwandu hwe monomer hwaive 12.5% ​​uye 7.89% (yakaverengerwa seyakasimba. Yakashandurwa kuita 40%, huwandu hwechigadzirwa hwaive 5.0% uye 3.2%), hwakakura kupfuura American Standard ye0.2% uye chiyero cheEuropean che0.5%. 380 yezvigadzirwa zvine huwandu husina kutaurwa hwe monomer, huwandu hwe monomer hunogona kunge hwakakwira. Kuwanda kwe PDMDAAC ine monomer kunopiwa nefomula inotevera: 411.
