Polydadmac.

Badanaa waxaa loo isticmaalaa sidii flocculant mararka qaarna waxaa lagu daraa algicide. Magacyada ganacsiga waxaa ka mid ah agequat400, St flocculant, casaanka lagu daaweeyo, cat floc, iwm. PDMDAAC waxay leedahay saameyn isku-dhafan oo leh wscp iyo poly (2-hydroxypropyl dimethyl ammonium chloride). 413 waxaa guud ahaan loo isticmaalaa sidii gargaar coagulant ah daaweynta biyaha warshadaha. Ka dib marka lagu daro alum coagulant, qiyaasta coagulant waxaa lagu badbaadin karaa 30%. Tusaale ahaan, ka dib marka lagu daro 20 mg / L polyaluminium chloride, ku dar 0.1-0.2 mg / L Polydimethyldiallyl ammonium chloride si loo kordhiyo waxtarka.

Kala duwanaanshaha miisaanka molecular-ka ee PDADMAC badanaa waa 50000 ilaa 700000, iyo isku-dhafka firfircoon ee 20% xalka biyaha waa 50-700cps; Miisaanka molecular-ka ee alaabada leh heerka sare ee polymerization waxay gaari kartaa 1000000 ilaa 300000, iyo isku-dhafka firfircoon waa 1000-3000 CPS. Isku-dhafka gudaha waa 80-300ml / g, iyo isku-dhafka sare wuxuu gaari karaa 1440ml / g. Badeecadu guud ahaan waa xal 10-50% ah oo leh cufnaan ah 1.02-1.10 g / ml. Qiyaasta biyaha la cabbo waxaa looga baahan yahay inay ka yar tahay 10mg / L (Taiwan).

Dhaqanka viscosity-ga ee xalka biyaha ee PDMDAAC wuxuu leeyahay saameyn polyelectrolyte oo muhiim ah. viscosity-ga gudaha ayaa hoos u dhaca marka la kordhiyo xaddiga milixda lagu daray. Marka fiirsashada NaCl ay ka weyn tahay 1 m, isbeddelka viscosity-ga gudaha ee fiirsashada milixda lagu daray waa mid aad u yar. viscosity-ga gudaha waxaa lagu cabbiraa Ubbelohde viscometer oo ku jira xalka 1 M NaCl 30 ℃, miisaanka molecular-ka ee celceliska viscosity-ga waxaa lagu heli karaa iyadoo loo eegayo qaacidada.

Miisaanka molecular-ka ee PDMDAAC waxaa laga heli karaa qaacidada soo socota, taas oo lagu cabbiro isku-dhafka gudaha ee xalka 1 M NaCl ee 30 ℃: 407.

Huang iyo Reichert waxay barteen miisaanka kulaylka ee PDMDAAC ee heerarka heerkulka kala duwan. Miisaanka oo luma 53.3-130 ℃ waxaa sabab u ah biyo la'aanta; Iskama beddelin inta u dhaxaysa 130-200 ℃; Miisaanka oo luma 200-310 ℃ waa 41.4%, taasoo ay ugu wacan tahay kala-go'a kulaylka. Ma jirin meel dhalaalaysa oo la helay intii lagu jiray habka kuleylka oo dhan. Heerkulka kala-guurka galaaska ee PDMDAAC oo leh miisaanka molecular-ka ee 33 kDa waa 8 ℃.

PDADMAC waxay ka sun yar tahay kalluunka rout-ka qaanso roobaadka marka loo eego chitosan (Waller et al. 1993). Si kastaba ha ahaatee, PDADMAC ee daaweynta biyaha waxay leedahay xaddidaad ku saabsan waxa ku jira monomer.

PDMDAAC ee Shiinaha waxay leedahay maaddo monomer sare leh. PDMDAAC ee laba warshadood oo kiimiko ah ayaa la tijaabiyay waxaana la ogaaday in maaddo monomer ay ahaayeen 12.5% ​​iyo 7.89% (lagu xisaabiyay inay adag tahay. Marka loo beddelo 40%, maaddo ku jirta badeecaddu waxay ahayd 5.0% iyo 3.2%), taasoo aad uga weynayd Heerka Mareykanka ee 0.2% iyo heerka Yurub ee 0.5% 380 ee alaabada leh maaddo monomer aan la cayimin, maaddo monomer ah ayaa laga yaabaa inay ka sarreyso. Dheelitirka gudaha ee monomer-ka ka kooban PDMDAAC waxaa lagu bixiyaa qaacidada soo socota: 411.
