Joang Polydadmac(poly diallyldimethylammonium chloride)

Hobaneng u khetha Polydadmac?

Joalo ka ha China ea ho etsa pampiri e 'nile ea laoloa ke lihlahisoa tse tala tsa limela tsa graminaceous,' me likhoele tsa limela tsa herbaceous li khutšoanyane, li na le li-heterocyte tse ngata, makhasi a joang a na le ho boloka tlaase le ho sefa metsi a fokolang ha ho etsoa pampiri.

Polydadmac e ka ntlafatsa bothata ba ho boloka metsi a tlaase le ho hloekisa metsi a fokolang ka mokhoa oa ho etsa pampiri, ho ntlafatsa tlhahiso le tšebeliso ea lihlahisoa tse tala, ho fokotsa litšenyehelo tsa lithane tsa pampiri le tšilafalo ea tikoloho.Polydadmac e ka boela ea ntlafatsa ts'ebetso ea ho hloekisa metsi ea makhasi le ho thehoa ha pampiri ea pampiri.

Sengoliloeng sena se etsa lipatlisiso ka litšobotsi tsa adsorption, ho boloka le ho sefa ha Polydadmac e nang le litekanyo tse fapaneng tsa limolek'hule e le li-additives ho makhasi a lehlaka le soeufalitsoeng, 'me u fumane sephetho se latelang.

1.Adsorption ea Polydadmac ho Reed Pulp

Boima bo bonyenyane ba limolek'hule tsa Polydadmac, bo fokotsa sekhahla sa adsorption ka bongata bo ntseng bo eketseha, bo ka bakoang ke hore boima ba molek'hule oa Polydadmac bo na le bokhoni bo boholo ba ho tšoasa anion.Ho hlokahala polydadmac e fokolang bakeng sa palo e lekanang ea anion tsamaisong e tletseng.

2.Tlhahiso ea ho hloekisa ea Polydadmac

Ka tekanyo e ntseng e eketseha ea polydadmac, tekanyo ea filtration e atisa ho fokotseha ebe e eketseha, 'me tekanyo ea filtration e haufi kapa e feta ea sekheo ha palo ea tlatsetso e fihla le ho feta 0.8%.Sena se bolela hore Polydadmac e ngata haholo e ke ke ea thusa ho sefa, empa e mpefatsa tlhoekiso ea metsi ea makhasi.Seo se bolela hore boima ba limolek'hule bo fapaneng Polydadmac bo bile le phello e ntle ea ho sefa pele ba tlatsa tefiso e mpe holim'a fiber ea pulp.

3. Tšusumetso ea ho boloka Polydadmac

Ha tekanyetso ea Polydadmac e ntse e eketseha, metsi a masoeu a makhasi a lehlaka a fokotseha butle pele, ebe a eketseha hape.Patlisiso ena e bonts'a hore ho eketsa polydadmac ho makhasi a lehlaka ho ka ntlafatsa haholo ho bolokoa ha likhoele tse khutšoane le likarolo tse ntle le tšebeliso ea thepa e tala, le ho fokotsa meroalo ea drainage.Ho ile ha fumanoa hore tekanyo e nepahetseng ea polydadmac ha e amehe ke boima ba tsona ba molek'hule;E nyane boima ba molek'hule ea polydadmac, e ntlafatsa phello ea ho boloka.Empa phapang ha e bonahale, 'me limolek'hule tse fapaneng tsa boima ba polydadmac li na le litlamorao tse ntle tsa ho boloka holim'a likhoele tsa pulp pele liqoso tse mpe li etsahala.

Qetello:

1.Polydadmac e nang le litekanyo tse fapaneng tsa limolek'hule e na le liphello tse ntle tsa ho hloekisa le ho boloka lehlaka la lehlaka;
2. Liphello tsa eona tse molemo tsa ho hloekisa le ho boloka sebaka se fihletsoeng ha palo ea polydadmac e sebelisitsoeng e le tlase ho tefiso e mpe holim'a likhoele tsa pulp tse tletseng;

3.Low molecular weight polydadmac hasgood retention effect.Boima ba molek'hule bo phahameng bo na le phello e ntle ea ho hloekisa.Leha ho le joalo, ha ho na phapang e kholo katlehong ea eona ho thusa ho sefa le ho boloka.
