Polydadmac.

Inowanzoshandiswa sekufa uye dzimwe nguva yakasanganiswa neyakagwinya. Mazita ekutengeserana anosanganisira zerac400, st floculant, pink kurapa, katsi floc, etc. pdmdaac ine wscp uye poly (2-hydroxypropyl amberide chloride). 413 inowanzoshandiswa sebetsero yekubatikana mumvura yemaindasitiri. Mushure mekuwedzera alum coagulant, iyo dosage yeCoagulant inogona kuponeswa ne30%. Semuenzaniso, mushure mekuwedzera 20 mg / l polandaminium chloride, Wedzera 0.1-0.2 mg / l polydimethyldillallllallyl amponium chloride kuti uwedzere kushanda zvakanaka.

Iyo molecular uremu hwePdadmac inowanzo kuve 50000 kusvika 700000, uye iyo Dynamic viscosity ye20% mhinduro mhinduro ndeye 50-700cps; Iyo smecular uremu hwezvigadzirwa zvine mwero wakakwira wePolymerization inogona kusvika 1000000 kusvika 300000, uye iyo Dynamic viscosity ndeye 1000-3000 CPS. Iyo intrinsic viscosity iri 80-300ml / g, uye yakakwira viscosity inogona kusvika 1440ml / g. Chigadzirwa chinowanzoitika 10-50% mhinduro ine density ye1.02-1.10 g / ml. Iyo Dosage mumvura yekunwa inofanirwa kuve isingasviki 10mg / l (Taiwan).

Iyo viscosity maitiro ePDMDAAC Tool Solution ine yakakosha polyelelectrony. Iyo intrinsic viscosity inoderera nekuwedzera kweiyo yakawedzerwa munyu yepazasi. Kana iyo NACL yekuvhara yakakura kupfuura 1 m, shanduko yeiyo intrinsic viscosity neiyo yakawedzerwa munyu yakasarudzika idiki. Iyo intrinsic viscosity inoyerwa neUbbelohde viscometer mu 1 m nacl solution pa30 ℃, uye viscosity avhareji molecular uremu hunogona kuwanikwa maererano neforamu.

Uremu hwePDMDAACT

[in] = 1.12 * 10-4m0. makumi masere nevaviri

HUang naReichert vakadzidza iyo inopisa uremu uremu hwePDMDAAC mune dzakasiyana tembiricha. 53.3-130 ℃ Kurasikirwa uremu kuri nekuda kwekurasikirwa kwemvura; Ramba usina kuchinjika pakati pe130-200 ℃; Kurema uremu muna 200-310 ℃ is 41.4%, iyo inokonzerwa nekuora kwekunyora. Hapana nzvimbo yekunyungudika yakawanikwa panguva yese yekudzidzisa. Iyo girazi transition tembiricha yePDMDAAC ine molecular uremu hwe33 Kda ndeye 8 ℃.

PDADMAC haina kuderera zvine muchetura kune muraraungu trout pane chitosan (Waller et al. 1993). Nekudaro, Pddmac yekubatwa kwemvura ine zvirambidzo pane monomer.

PDMDAAC muChina ine yakakwira monoomer. Iyo PDMDAAC yezvirimwa zviviri zvemakemikari zvakaedzwa uye akawana kuti Monomer Zviri mukati mae.5% uye 7.8% muChigadzirwa, iyo yechigadzirwa uye 3.2%), iyo yaive yakakura kupfuura iyo America Chiyero che 0,2 uye iyo European Standard ye 0.5%. 380 Zvezvigadzirwa zvine zvisingataurwe Monomer zvemukati, iyo monermer yezviri inogona kunge yakakwira. Iyo Intrinsic viscosity yePDMDAac ine Monomer inopihwa neiyo inotevera formula: 411.
