Polydadmac

Badanaa waxaa loo isticmaalaa sida flocculant oo mararka qaarkood lagu daro algicide.Magacyada ganacsiga waxaa ka mid ah agequat400, St flocculant, daawo casaan ah, floc bisadaha, iwm. PDMDAAC waxay leedahay saameyn isku mid ah wscp iyo poly (2-hydroxypropyl dimethyl ammonium chloride).413 waxaa guud ahaan loo isticmaalaa gargaarka xinjirowga ah ee daaweynta biyaha warshadaha.Ka dib marka lagu daro alum coagulant, qiyaasta xinjirowga 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.

Miisaanka kelli ee PDADMAC inta badan waa 50000 ilaa 700000, iyo viscosity firfircoon ee 20% xal aqueous waa 50-700cps;Miisaanka kelli ee alaabooyinka leh heerar sare oo polymerization ah waxay gaari karaan 1000000 ilaa 300000, viscosity firfircooni waa 1000-3000 CPS.Viscosity-ka gudaha waa 80-300ml/g, viscosity sarena wuxuu gaari karaa 1440ml/g.Badeecada guud ahaan waa 10-50% xal cufnaanta 1.02-1.10 g / ml.Qiyaasta biyaha la cabbo waxaa looga baahan yahay inay ka yaraato 10mg/L (Taiwan).

Dhaqanka viscosity ee PDMDAAC aqueous aqueous wuxuu leeyahay saamayn polyelectrolyt ah oo muhiim ah.Viscosity-ga gudaha ayaa hoos u dhacaya marka ay korodho xoogga milixda ee lagu daray.Marka fiirsashada NaCl ay ka weyn tahay 1 m, isbeddelka viscosity-ga gudaha ee xoojinta milixdu waa mid yar.Viscosity-ka gudaha waxa lagu qiyaasaa Ubbelohde viscometer ee 1 M NaCl xal 30 ℃, iyo celceliska viscosity miisaanka kelli waxa lagu heli karaa si waafaqsan qaacidada.

Miisaanka molecular ee PDMDAAC waxaa laga heli karaa qaacidooyinka soo socda, kaas oo viscosity gudaha lagu qiyaasay 1 M NaCl xal 30 ℃: 407.

Huang iyo Reichert waxay barteen dhimista kulaylka ee miisaanka kulaylka ee PDMDAAC heerar heerkul kala duwan.53.3-130 ℃ miisaanka oo yaraada waxaa sabab u ah biyo lumin;Iska ilaali inta u dhaxaysa 130-200 ℃;Miisaanka dhimista ee 200-310 ℃ waa 41.4%, taas oo ay ugu wacan tahay kuleylka kuleylka.Ma jiro meel dhalaalaysa oo la helay intii lagu jiray habka kuleylka oo dhan.Heerkulka kala-guurka dhalada ee PDMDAAC ee leh miisaanka kelli ee 33 kDa waa 8 ℃.

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

PDMDAAC ee Shiinaha waxay leedahay maaddo monomer sare leh.PDMDAAC ee laba warshadood oo kiimiko ah ayaa la tijaabiyey waxaana la ogaaday in waxa ku jira monomer ay ahaayeen 12.5% ​​iyo 7.89% (lagu xisaabiyey sidii adag. Loo beddelay 40%, waxa ku jira alaabtu waxay ahayd 5.0% iyo 3.2%), taas oo aad uga weyn tan Maraykanka. Heerka 0.2% iyo heerka Yurub ee 0.5%.380 ee alaabta leh ka kooban monomer aan la cayimin, waxa ku jira monomer ayaa laga yaabaa in uu sareeyo.Mawduuca hoose ee PDMDAAC ka kooban monomer waxa lagu bixiyaa qaacidooyinka soo socda: 411.
