Indima Yomlingo yePolyacrylamide Kwintsimi Yokwenza Iphepha

I-Polyacrylamideligama eliqhelekileyo lee-homopolymers ze-acrylamide okanye ii-copolymers kunye nezinye ii-monomers. Yenye yezona polymers zinyibilikayo emanzini ezisetyenziswa kakhulu. I-Polyacrylamide ikhona ngohlobo lweegranules ezimhlophe kwaye inokwahlulwa ibe ziintlobo ezine: i-non-ionic, i-anionic, i-cationic, kunye ne-amphoteric ionic.

Ukusetyenziswa kwePolyacrylamide kwiCandelo lokwenza iphepha

Inkqubo yokwenza iphepha inamanqanaba aliqela, kuquka ukucola, ukuhluza, ukucoca, ukucokisa, kunye nokwenziwa. Ngexesha lezi nkqubo, kuvela ukungcola okuhlukeneyo okufana neefayibha, izizalisi, kunye neefines. Ukuba oku kungcola akususwanga kakuhle kwi-pulp, kunokukhokelela kwiingxaki ezinje ngokuphuma kwamanzi kakubi kunye nokuqina kwephepha okuphantsi. I-Polyacrylamide isetyenziswa kakhulu njenge-dispersant, i-retention aid, i-drainage aid, i-flocculant, kunye ne-sizeing agent kwinkqubo yokwenza iphepha.

Ⅰ. Isisasazi

Ukongeza i-polyacrylamide dispersant ngexesha lenkqubo yokwenza iphepha kunokuthintela ngempumelelo ukuhlangana kweefayibha kwaye kuphucule ukufana kwephepha. Ubungakanani obuncinci bokongeza bunokukhuthaza ukusasazeka okuhle kweefayibha zokwenza iphepha kwaye bufezekise isiphumo esihle sokwenza iphepha. Bunokuphucula ukufana kwepulp kunye nokuthamba kwephepha, kwaye buphucule iimpawu zokuqina kwephepha. Ifanelekile kwiimveliso ezahlukeneyo zephepha zasekhaya ezifana nephepha langasese, ii-napkin, izicubu zobuso, kunye namanye amaphepha amancinci. Kwezinye iifektri zephepha, inokuthatha indawo yePolyethylene Oxide (PEO) ngokupheleleyo.

Ⅱ. Uncedo Lokugcina Impahla

I-PAM isetyenziswa kakhulu njengesixhobo sokugcina izinto kwishishini lokwenza amaphepha ukuze kwandiswe izinga lokugcina izinto ezisetyenzisiweyo kunye nokunciphisa ukukhutshwa kwamanzi amdaka. Umgaqo wayo osebenzayo kukwenza ii-flocs ezinkulu ezinamasuntswana amancinci, anokususwa ngokulula kwi-pulp ngokuhluza okanye ngokudibanisa inkunkuma.

Ⅲ. Uncedo lokuhambisa amanzi

I-PAM ikwanceda ekukhupheni amanzi kwinkqubo yokwenza iphepha. Iyandisa izinga lokukhupha amanzi, ivumela ukucocwa kwamanzi ngokukhawuleza nangokufanelekileyo kwephepha kumatshini wephepha. Oku kunceda ukwandisa isantya sokuvelisa nokunciphisa ukusetyenziswa kwamandla ngokunciphisa ixesha lokomisa elifunekayo ephepheni.

Ⅳ. Iarhente yokulinganisa

Kwezinye iimeko, i-polyacrylamide isetyenziswa njenge-ejenti yokulinganisa ekwenzeni iphepha ukulawula ukungena kwamanzi kunye nolunye ulwelo kwiphepha lephepha. Oku kunceda ekufezekiseni iipropati ezifunekayo ezifana nokumelana namanzi kunye nokubamba i-inki, ngakumbi xa iphepha lifuna ukumelana nokufuma okanye iinkqubo zokuprinta.

Ⅴ. I-Flocculant

Ngexesha lenkqubo yokucocwa kwamanzi amdaka kwiifektri zamaphepha, i-polyacrylamide ingasetyenziswa njenge-flocculant ukususa izinto eziqinileyo ezixhonyiweyo kunye nongcoliseko emanzini amdaka. Inceda ekwenzeni amasuntswana amakhulu abizwa ngokuba yi-flocs, anokususwa ngokulula ngenkqubo yokunyibilikisa okanye yokuhluza. Oku kunceda ekunciphiseni ungcoliseko lwamanzi kunye nokuphucula uzinzo lokusingqongileyo lweshishini lokwenza amaphepha.

Lilonke, iipropati ezahlukeneyo ze-polyacrylamide zenza ukuba ibe sisongezelelo esibalulekileyo kwishishini lokwenza iphepha, nto leyo enegalelo ekuphuculeni ukusebenza kakuhle, umgangatho wemveliso, kunye nokusebenza kakuhle kweemveliso zephepha. Ukusetyenziswa kwe-polyacrylamide kwicandelo lokwenza iphepha kugubungela lonke uthotho lweshishini lokwenza iphepha, ukusuka ekuvelisweni kwephepha ukuya kunyango lwamanzi amdaka. Ayiphuculi nje kuphela umgangatho kunye nokusebenza kakuhle kwephepha, inciphisa iindleko zemveliso, kodwa ikwanegalelo elihle ekukhuselweni kokusingqongileyo.
