Polydadmac.

Ngokuqhelekileyo isetyenziswa njenge-flocculant kwaye ngamanye amaxesha idityaniswe ne-algicide.Amagama okurhweba aquka i-agequat400, i-St flocculant, i-pink cure, i-cat floc, njl.I-413 isetyenziswa ngokubanzi njengoncedo lwe-coagulant kunyango lwamanzi kwimizi-mveliso.Emva kokongeza i-alum coagulant, umthamo we-coagulant unokugcinwa ngama-30%.Ngokomzekelo, emva kokufaka i-20 mg / L i-polyaluminium chloride, yongeza i-0.1-0.2 mg / L I-Polydimethyldiallyl ammonium chloride ukwandisa ukusebenza kakuhle.

Uluhlu lwe-molecular weight ye-PDADMAC ngokuqhelekileyo luyi-50000 ukuya kwi-700000, kwaye i-viscosity eguquguqukayo ye-20% isisombululo samanzi yi-50-700cps;Ubunzima be-molecular yeemveliso ezinezinga eliphezulu le-polymerization linokufikelela kwi-1000000 ukuya kwi-300000, kunye ne-viscosity eguquguqukayo yi-1000-3000 CPS.I-intrinsic viscosity yi-80-300ml / g, kwaye i-viscosity ephezulu inokufikelela kwi-1440ml / g.Imveliso ngokubanzi isisombululo se-10-50% kunye noxinano lwe-1.02-1.10 g / ml.Umthamo kumanzi okusela kufuneka ube ngaphantsi kwe-10mg / L (Taiwan).

Ukuziphatha kwe-viscosity ye-PDMDAAC isisombululo samanzi sinesiphumo esibalulekileyo se-polyelectrolyte.I-intrinsic viscosity iyancipha ngokunyuka kwe-concentration yetyuwa eyongezelelweyo.Xa i-concentration ye-NaCl ingaphezu kwe-1 m, utshintsho lwe-viscosity yangaphakathi kunye ne-concentration yetyuwa eyongezelelweyo incinci.I-intrinsic viscosity ilinganiswa ngu-Ubbelohde viscometer kwisisombululo se-1 M NaCl kwi-30 ℃, kunye ne-viscosity avareji ubunzima be-molecular inokufumaneka ngokwefomula.

Ubunzima be-molecular of PDMDAAC bunokufumaneka kwifomula elandelayo, apho i-viscosity yangaphakathi ilinganiswa kwisisombululo se-1 M NaCl kwi-30 ℃: 407.

U-Huang kunye noReichert bafunde ukwehla kobunzima be-thermal yePDMDAAC kwiindawo ezahlukeneyo zobushushu.53.3-130 ℃ ukwehla kobunzima ngenxa yokulahleka kwamanzi;Gcina ungatshintshi phakathi kwe-130-200 ℃;Ukulahleka kwesisindo kwi-200-310 ℃ yi-41.4%, okubangelwa ukubola kwe-thermal.Akukho ndawo yokunyibilika ifunyenwe ngexesha lonke lenkqubo yokufudumeza.Ubushushu beglasi benguqu yePDMDAAC enobunzima bemolekyuli ye-33 kDa yi-8 ℃.

I-PDADMAC ayinatyhefu encinci kwi-rainbow trout kune-chitosan (Waller et al. 1993).Nangona kunjalo, iPDDMAC yonyango lwamanzi inezithintelo kumxholo we-monomer.

I-PDMDAAC e-China inomxholo ophezulu we-monomer.I-PDMDAAC yezityalo ezimbini zeekhemikhali zavavanywa kwaye zafumanisa ukuba iziqulatho ze-monomer ziyi-12.5% ​​kunye ne-7.89% (ibalwa njengento eqinile. Iguqulelwe kwi-40%, umxholo wemveliso wawuyi-5.0% kunye ne-3.2%), eyayinkulu kakhulu kune-American. Umgangatho we-0.2% kunye nomgangatho waseYurophu we-0.5%.I-380 yeemveliso ezinomxholo we-monomer ongachazwanga, umxholo we-monomer unokuba phezulu.I-intrinsic viscosity yePDMDAAC equlethe i-monomer inikwa le fomula ilandelayo: 411.
