Njani Polydadmac(poly diallyldimethylammonium chloride)

Kutheni ukhetha iPolydadmac?

Njengoko iphepha laseTshayina kudala lilawulwa yi-graminaceous plant fiber ekrwada, kunye nemicu yesityalo esine-herbaceous imfutshane, inomxholo ophezulu we-heterocytes, i-pulp yengca inokugcinwa okuphantsi kunye nokuhluzwa kwamanzi okungahambi kakuhle kwinkqubo yokwenza iphepha.

I-Polydadmac inokuphucula ingxaki yokugcinwa okuphantsi kunye nokuhluthwa kwamanzi okungahambi kakuhle kwinkqubo yokwenza iphepha, ukuphucula imveliso kunye nokusetyenziswa kwezinto eziluhlaza, ukunciphisa iindleko zeetoni zephepha kunye nokungcola kwendalo.I-Polydadmac inokuphucula ukusebenza kokucoca kwamanzi kwi-pulp kunye nokwakhiwa kwephepha lephepha.

Eli nqaku liphanda i-adsorption, ukugcinwa, kunye neempawu zokuhluza ze-Polydadmac ezinobunzima bemolekyuli ezahlukeneyo njengezongezo kwi-pulp yengcongolo ejiyiweyo, kwaye ufumane esi sigqibo silandelayo.

1.IAdsorption yePolydadmac kwiReed Pulp

Ubunzima bemolekyuli obuncinci bePolydadmac, kokukhona ukuncipha kwesantya se-adsorption kunye nesixa esonyukayo soncedo, olunokuthi lube ngenxa yokuba buncinci ubunzima bemolekyuli yePolydadmac, amandla amakhulu okubambisa iianion.I-polydadmac encinci iyadingeka kwixabiso elifanayo le-anion kwinkqubo egcweleyo.

2.Isiphumo sokuhluza sePolydadmac

Ngokunyuka kwedosi ye-polydadmac, idigri yokucoca ithande ukuhla kwaye inyuke, kwaye idigri yokuhluza isondele okanye ide igqithe kwisithuba esingenanto xa isixa esongezelelweyo sifikelela kwaye sidlula i-0.8%.Oku kuthetha ukuba iPolydadmac eninzi kakhulu ayinakunceda ukuhluzwa, kodwa yenza mandundu ukuhluzwa kwamanzi kwipulp.Oko kuthetha ukuba ubunzima bemolekyuli yePolydadmac yaba nefuthe elingcono lokucoca ngaphambi kokuba igcwalise intlawulo embi kumphezulu wefiber.

3.Isiphumo sokugcinwa kwePolydadmac

Njengoko idosi yePolydadmac isanda, ukuxinwa kwamanzi amhlophe kwi-pulp yengcongolo yehla ngokuthe ngcembe kuqala, kwaye yonyuka kwakhona.Olu phando lubonisa ukuba ukongeza i-polydadmac kwi-pulp yengcongolo kunokuphucula kakhulu ukugcinwa kweentsinga ezimfutshane kunye namacandelo amahle kunye nokusetyenziswa kwezinto eziluhlaza, kunye nokunciphisa imithwalo yamanzi.Kwafunyaniswa ukuba i-dosage efanelekileyo ye-polydadmac ayichaphazeli ubunzima babo be-molecular;Ubuncinci ubunzima bemolekyuli yepolydadmac, ngcono isiphumo sokugcina.Kodwa umahluko awubonakali, kwaye i-molecular weight polydadmac eyahlukileyo ineziphumo ezingcono zokugcina kumphezulu we-pulp fibers egcweleyo ngaphambi kokuba kuhlawulwe kakubi.

Isiphelo:

I-1.I-Polydadmac enezisindo ezahlukeneyo ze-molecular ine-filtration efanelekileyo kunye nemiphumo yokugcinwa kwi-pulp yengcongolo;
I-2.Imiphumo engcono yokucoca kunye nokugcinwa kwendawo efunyenweyo xa inani le-polydadmac elisetyenzisiweyo lingaphantsi kwentlawulo engalunganga kumphezulu wemicu ye-pulp egcweleyo;

I-3.I-molecular weight ephantsi ye-polydadmac inefuthe elihle lokugcina.Nangona kunjalo, akukho mmahluko obalulekileyo ekusebenzeni kwayo ekuncedeni ukuhluzwa kunye nokugcinwa.
