Olee otú Polydadmac (poly diallyldimethylammonium chloride)

Kedu ihe kpatara ịhọrọ Polydadmac?

Dị ka China si papermaker kemgbe ogologo oge na-achịkwa graminaceous osisi fiber raw material, na herbaceous osisi eri dị mkpụmkpụ, na elu ọdịnaya nke heterocytes, ahịhịa pulp nwere obere njide na ogbenye mmiri filtration na papermaking usoro.

Polydadmac nwere ike imeziwanye nsogbu nke nkwụsịtụ na mmiri na-adịghị mma na usoro nhazi akwụkwọ, meziwanye arụpụtaghị ihe na iji ihe eji eme ihe, belata ọnụ ahịa nke akwụkwọ na mmetọ gburugburu ebe obibi.Polydadmac nwekwara ike imeziwanye arụmọrụ nzacha mmiri nke pulp na nhazi mpempe akwụkwọ.

Edemede a na-enyocha njirimara mgbasa ozi, njide na nzacha nke Polydadmac nwere oke igwe dị iche iche dị ka mgbakwunye na pulp ahịhịa acha ọcha, wee nweta nkwubi okwu a.

1.Adsorption nke Polydadmac na Reed Pulp

Obere molecular arọ nke Polydadmac, na-abawanye mbelata nke mgbasa ozi na ọnụ ọgụgụ na-arịwanye elu nke inyeaka, nke nwere ike ịbụ n'ihi na ịdị arọ nke Polydadmac dị ntakịrị, na-enwekwu ike ijide anions.A na-achọrọ obere polydadmac maka otu ego anion na sistemu juru.

2.Nyocha mmetụta nke Polydadmac

Site na ọnụọgụ na-abawanye nke polydadmac, ogo nzacha na-achọ ibelata wee na-abawanye, na ogo filtration dị nso ma ọ bụ karịa karịa nke oghere mgbe ego mgbakwunye ruru ma gafere 0.8%.Nke a pụtara na ọtụtụ Polydadmac enweghị ike inye aka nzacha, mana ọ na-akawanye mma nzacha mmiri nke pulp.Nke ahụ pụtara ịdị arọ molekụla dị iche iche Polydadmac nwere mmetụta nzacha ka mma tupu ha ejuo ụgwọ na-adịghị mma n'elu elu fiber pulp.

3.Retention mmetụta nke Polydadmac

Ka usoro onunu ogwu nke Polydadmac na-abawanye, mkpokọta mmiri ọcha nke ahịhịa ahịhịa na-eji nwayọọ nwayọọ na-ebelata nke mbụ, wee na-abawanye ọzọ.Nnyocha a na-egosi na ịgbakwụnye polydadmac na pulp ahịhịa nwere ike imeziwanye njide nke obere eriri na ihe ndị dị mma na iji akụrụngwa eme ihe, ma belata ibu mmiri.Achọpụtara na usoro ọgwụgwọ kachasị mma nke polydadmac adịghị emetụta ịdị arọ ha;Dị ntakịrị arọ molekụla nke polydadmac, ka mmetụta njide dị mma.Mana ọdịiche ahụ apụtachaghị, yana polydadmac dị arọ molekụla dị iche iche nwere mmetụta njide ka mma n'elu eriri pulp juputara tupu ebubo ọjọọ emee.

Mmechi:

1.Polydadmac dị iche iche dị arọ dị iche iche nwere ezigbo nzacha na njigide mmetụta na ahịhịa ahịhịa;
2.Its mma filtration na njigide mmetụta areachieved mgbe ego nke polydadmac eji bụ ihe na-adịghị mma ụgwọ n'elu nke jupụtara pulp eriri;

3.Low molecular arọ polydadmac hasgood retention effect.High molecular arọ nwere ezigbo nzacha mmetụta.Otú ọ dị, ọ dịghị nnukwu ọdịiche dị na irè ya n'inyere nzacha na njigide.
