Gukoresha polyacrylamide munganda zimpapuro —— Bitandukanye, flocculant

Bitatanye, flocculant

Ikwirakwizwa rya polyacrylamide mu nganda zimpapuro ahanini ni cacic polyacrylamide ifite uburemere buke bwa molekile.Kuberako urunigi rwa molekuline rurimo amatsinda ya carboxyl, igira ingaruka zo gukwirakwiza fibre zishizwemo nabi, irashobora kongera ububobere bwimbuto, ifasha guhagarika fibre, kandi irashobora gukora neza Irashobora kunoza uburinganire bwimpapuro, kandi nibikorwa byiza cyane ikwirakwiza kuri fibre ndende.Amphoteric polyacrylamide ikoreshwa nka flocculant yo gutunganya amazi muruganda rwimpapuro.Itsinda ryacyo rya amide rishobora gukora hydrogène ihuza ibintu byinshi mumazi y’amazi, bityo irashobora guhuza ibice byanyanyagiye mumazi hamwe no kubiteranya.Yorohereza gutuza no kuyungurura ibice.Ugereranije n’ibindi binyabuzima bitagira umubiri, amphoteric polyacrylamide ifite ibyiza byubwoko bwuzuye, gukoresha bike mu musaruro, umuvuduko ukabije wihuse, umusaruro muke, hamwe n’ubuvuzi bworoshye nyuma y’ubuvuzi, nibindi, bishobora kuzuza ibisabwa mu gutunganya amazi mabi atandukanye.

Muri make, polyacrylamide igira uruhare runini mubikorwa byimpapuro.Irashobora gukoreshwa nkibikoresho byo kuringaniza impapuro, gushimangira umukozi, gutatanya, infashanyo zungurura, nibindi. Intego yabyo nukuzamura uburinganire bwimpapuro, kuzamura neza ubwiza nimbaraga zimpapuro, ndetse no kuzamura igipimo cyo kugumana ibyuzuye na fibre nziza, kugabanya Kugabanya igihombo cyibikoresho fatizo, kunoza imikorere yo kuyungurura no kugabanya ibidukikije.

CPAM ikoreshwa nkibikoresho bishimangira, binyuze mugushinga ionic isano hagati ya cations na anion kuri fibre, irashobora kwamamazwa kuri fibre fibre, mugihe amide amide ihuza hamwe na hydroxyl mumatsinda kugirango ibeho imigozi ya hydrogène, ikazamura imbaraga zihuza fibre.Ongera imbaraga zimpapuro. Kwiyongera gukurikiranye kwa APAM wongeyeho rosin na aluminium sulfate nabyo birashobora kubona ingaruka nziza zo gushimangira iyo bikoreshejwe pulp, ariko ingaruka zo gushimangira APAM zizagabanuka hamwe no kwiyongera kwuzuye.
