Sei Polydadmac (poly diallyldimethylammonium chloride)

Sei uchisarudza Polydadmac?

Sezvo kuChina kugadzira mapepa kwagara kuchidzorwa negraminaceous plant fiber raw materials, uye herbaceous plant fibers ipfupi, ine yakakwirira yeheterocytes, uswa pulp ine yakaderera kuchengetwa uye kusachena kwemvura kusefa mukugadzira mapepa.

Polydadmac inogona kuvandudza dambudziko rekudzikisa uye kusvibiswa kwemvura kwakashata mukugadzira mapepa, kuvandudza kubereka uye kushandiswa kwezvinhu zvakasvibirira, kuderedza mari yematani emapepa uye kusvibiswa kwezvakatipoteredza.Polydadmac inogona zvakare kuvandudza kusefa kwemvura kuita kwe pulp uye kuumbwa kwepepa bepa.

Ichi chinyorwa chinoongorora adsorption, kuchengetwa, uye kusefa hunhu hwePolydadmac ine akasiyana mamorekuru uremu sekuwedzera pane yakasvibiswa tsanga pulp, uye uwane mhedzisiro inotevera.

1.Adsorption yePolydadmac paReed Pulp

Huremu hudiki hwemamorekuru ePolydadmac, ndiko kuwedzera kuderera kweyero yekushambadza nekuwedzera huwandu hwekubatsira, izvo zvingave zvichikonzerwa nekuti idiki huremu hwePolydadmac, kugona kukuru kubata anions.Iyo shoma polydadmac inodiwa kune imwecheteyo anion mune yakazara saturated system.

2.Kusefa mhedzisiro yePolydadmac

Nekuwedzera kwedosi yepolydadmac, dhigirii rekusefa rinoita kudzikira uye richibva rawedzera, uye dhigirii rekusefa riri pedyo kana kutopfuura iro repasina kana huwandu hwekuwedzera hwasvika nekupfuura 0.8%.Izvi zvinoreva kuti yakawandisa Polydadmac haigone kubatsira kusefa, asi inowedzera kusefa kwemvura kwepulp.Izvi zvinoreva kuti akasiyana molecular uremu Polydadmac yaive nani kusefa mhedzisiro isati yazadza iyo yakaipa charge pane pulp fiber pamusoro.

3.Kuchengetedza mhedzisiro yePolydadmac

Sezvo dosage yePolydadmac inowedzera, iyo chena yemvura yetsanga pulp zvishoma nezvishoma inodzikira kutanga, yobva yawedzera zvakare.Ongororo iyi inoratidza kuti kuwedzera polydadmac kune tsanga pulp kunogona kuvandudza zvakanyanya kuchengetwa kwemafiber mapfupi uye zvikamu zvakanaka uye kushandiswa kwezvinhu zvakasvibiswa, uye kuderedza mitoro yemvura.Yakawanikwa kuti iyo yakakwana dosage yepolydadmac haina kukanganiswa nehuremu hwavo hwema molecular;Iyo idiki iyo molecular huremu hwepolydadmac, zviri nani kuchengetedza maitiro.Asi mutsauko hausi pachena, uye akasiyana mamorekuru huremu polydadmac ane mhedzisiro irinani yekuchengeta pamusoro peakazara pulp fibers kusati kwaitika mhosva dzisina kunaka.

Mhedziso:

1.Polydadmac ine uremu hwakasiyana hwema molecular ine filtration yakanaka uye mhedzisiro yekuchengeta patsanga pulp;
2.Its better filtration and retention effects areachieved apo uwandu hwepolydadmac hunoshandiswa huri shoma pane yakaipa mhosva pamusoro pe saturated pulp fibers;

3.Low molecular weight polydadmac hasgood retention effect.High molecular weight ine yakanaka yekusefa.Nekudaro, hapana misiyano yakakosha mukubudirira kwayo mukubatsira kusefa nekuchengetedza.
