Momwe Polydadmac (poly diallyldimethylammonium chloride)

Chifukwa chiyani musankhe Polydadmac?

Monga kupanga mapepala ku China kwakhala kulamulidwa ndi zida za graminaceous chomera, ndipo ulusi wa herbaceous chomera ndi waufupi, wokhala ndi ma heterocyte ambiri, zamkati zaudzu zimakhala ndi kusungirako kochepa komanso kusefera kosauka kwamadzi popanga mapepala.

Polydadmac ikhoza kukonza vuto la kusungirako pang'ono komanso kusefa kwamadzi kosauka popanga mapepala, kupititsa patsogolo zokolola ndi kugwiritsa ntchito zipangizo zopangira, kuchepetsa mtengo wa matani a mapepala ndi kuwonongeka kwa chilengedwe.Polydadmac imathanso kupititsa patsogolo kusefera kwamadzi pazamkati komanso kupanga mapepala.

Nkhaniyi ikufufuza za kutsatsa, kusungidwa, ndi kusefera kwa Polydadmac yokhala ndi masikelo osiyanasiyana a mamolekyulu monga zowonjezera pazakudya za bango lowuchitsidwa, ndikupeza mawu otsatirawa.

1.Adsorption ya Polydadmac pa Reed Pulp

Kulemera kwa mamolekyu ang'onoang'ono a Polydadmac, kumachepetsanso kuchuluka kwa adsorption ndi kuchuluka kwa chithandizo, chomwe chingakhale chifukwa chakuti kuchepa kwa molekyulu ya Polydadmac, mphamvu yaikulu yogwira anions.Polydadmac yocheperako imafunikanso kuchuluka kwa anion mu dongosolo lodzaza.

2.Kusefa zotsatira za Polydadmac

Ndi kuchuluka kwa mlingo wa polydadmac, digiri ya kusefera imacheperachepera kenako ndikuwonjezeka, ndipo digiri ya kusefera imakhala pafupi kapena kupitilira yomwe ikusowekapo pamene kuchuluka kowonjezera kumafika ndikupitilira 0.8%.Izi zikutanthauza kuti Polydadmac yochuluka sikungathandize kusefa, koma kumawonjezera kusefera kwamadzi.Izi zikutanthauza kulemera kwa maselo a Polydadmac anali ndi zotsatira zosefera bwino asanakhutitse chiwopsezo choyipa pazamkati.

3.Kusunga zotsatira za Polydadmac

Mlingo wa Polydadmac ukachulukirachulukira, kuchuluka kwa madzi oyera a bango kumachepa pang'onopang'ono, kenako kumawonjezekanso.Kafukufukuyu akuwonetsa kuti kuwonjezera polydadmac ku bango zamkati kumatha kupititsa patsogolo kwambiri kusungidwa kwa ulusi waufupi ndi zigawo zabwino komanso kugwiritsa ntchito zinthu zopangira, komanso kuchepetsa kuchuluka kwa ngalande.Zinapezeka kuti mlingo woyenera wa polydadmac sukhudzidwa ndi kulemera kwawo kwa maselo;Kuchepetsa kulemera kwa maselo a polydadmac, kumapangitsanso kusungirako bwino.Koma kusiyana kwake sikodziwikiratu, ndipo ma molekyulu osiyanasiyana olemera a polydadmac amakhala ndi zotsatira zabwino zosungira pamwamba pa ulusi wodzaza zamkati zisanachitike milandu yoyipa.

Pomaliza:

1.Polydadmac yokhala ndi zolemetsa zosiyanasiyana zama cell imakhala ndi kusefera kwabwino komanso kusungirako zotsatira za bango;
2.Kusefedwa kwabwinoko ndi kusungirako zotsatira zomwe zapezeka pamene kuchuluka kwa polydadmac komwe kumagwiritsidwa ntchito kumakhala kochepa kusiyana ndi mtengo woipa pamwamba pa ulusi wodzaza zamkati;

3.Low molecular weight polydadmac hasgood retention effect.High molecular weight imakhala ndi zotsatira zabwino zosefera.Komabe, palibe kusiyana kwakukulu pakuchita bwino kwake pothandizira kusefera ndi kusunga.
