Ingaruka yumuti urwanya amazi kumiterere yo gutwikisha impapuro

Hamwe niterambere ryihuse ryinganda zimpapuro, cyane cyane impapuro zometseho zatejwe imbere byihuse, inganda zo gucapa kubisabwa impapuro zujuje ubuziranenge ziragenda ziyongera. Kugirango umenye neza icapiro ryiza, hejuru yimpapuro zometseho zigomba kuba zifite ubushobozi bwo kurwanya ubushyamirane butose. Kurwanya ibishishwa bitose bivuga urwego rwo kwangirika hejuru yimpapuro nyuma yikibanza runaka cyimpapuro namakarito byatewe no guterana amagambo munsi yumuvuduko runaka, ibyo bikaba bigaragaza ubushobozi bwubuso bwimpapuro budashobora kurimburwa nubushuhe butose.

Kandi kubipapuro bitarimo amazi bitarimo amazi hamwe nibisabwa byihariye, kugirango bigire ubushobozi bwo kubona ubushobozi bwo kutagira amazi no kurwanya amazi, mugikorwa cyo gukora impapuro, hiyongereyeho uburyo bwo gupima ingano ya agent ingana na sizing agent, ingaruka yihuta ni ukongeramo inyongeramusaruro zamazi mugikorwa cyo gutegura igifuniko, kugirango igipfundikizo kibone amazi meza.

Muri icyo gihe, hashingiwe ku gutekereza ku mutekano no kurengera ibidukikije, ibisabwa mu rwego rw’igihugu ku mpapuro zipfunyika ibiryo hamwe n’impapuro zo mu rugo bigenda birushaho gukomera, none ubu ni byinshi byo gukoresha polyamide polyurea formaldehyde resin (PAPU) yangiza amazi. PAPU ikoreshwa cyane, kubera ko idafite fordehide yubusa, kandi irihuta, ikora iyo ivuye kuri mashini, kandi irashobora kandi kunoza neza guhuza nimpapuro zometse mugikorwa cyo gucapa.

PAPU ifite porogaramu ikomeye kuri pH agaciro, kandi viscosity ya PAPU yongewe kumarangi irahagaze kandi umuvuduko wo gukira urihuta. Urunigi rwa molekile ya PAPU rurimo itsinda rya chloroethanol hamwe nitsinda rya polyamine amatsinda abiri akora, murirwo tsinda rya chloroethanol hamwe nudusiga amarangi bitanga imiti ihuza imiti, itsinda rya polyamine hamwe nugusiga amarangi bifatanyiriza hamwe kugirango bibe ionic bond, guhuza imiyoboro ihuza imiyoboro ya firime ikiza, niyo soko nyamukuru yo kurwanya amazi ya PAPU.

Mu mikoreshereze nyayo, PAPU ntishobora gukora gusa imiti ihuriweho na krahisi isize, ariko kandi irashobora gukora ionic bond hamwe na styrene butadiene latex, kandi kurwanya ubukana bwamazi yo gutwikira byiyongera. Byongeye kandi, intege nke za cationic agent ya PAPU irwanya amazi irashobora kandi kubyara micro-flocculation hamwe na anion mugipfundikizo, kunoza ubunebwe, ububobere no kwemererwa kurwego, kandi binonosora imikorere yo gucapa impapuro zuzuye.

Umutungo wa rheologiya ni ikimenyetso cyingenzi cyerekana irangi, imiti yo mu bwoko bwa PAPU irwanya amazi irashobora kongera ubwiza bwirangi, ukongeraho imiti yo mu bwoko bwa PAPU irwanya amazi nyuma yo gutakaza amazi y’irangi kugabanuka, gufata amazi ni byiza. Ubwoko bwa PAPU bwihanganira amazi burakwiriye mugutegura irangi ryinshi ryinshi, kandi imikorere yo gufata amazi irangi nibyiza.
