Udindo Wamatsenga wa Polyacrylamide M'munda Wopanga Mapepala

Polyacrylamidendi mawu wamba kutanthauza homopolymers acrylamide kapena copolymers ndi monomers ena. Ndi imodzi mwa ma polima osungunuka m'madzi omwe amagwiritsidwa ntchito kwambiri. Polyacrylamide ilipo mu mawonekedwe a ma granules oyera ndipo imatha kugawidwa m'mitundu inayi: ionic ionic, anionic, cationic, ndi amphoteric ionic.

Kugwiritsa Ntchito Polyacrylamide M'munda Wopanga Mapepala

Kupanga mapepala kumakhala ndi magawo angapo, kuphatikiza pulping, kuwunika, kuyeretsa, kuyenga, ndi kupanga. Pazigawozi, zonyansa zosiyanasiyana monga ulusi, ma fillers, ndi chindapusa zimapangidwa. Ngati zonyansazi sizikuchotsedwa bwino pazamkati, zimatha kuyambitsa mavuto monga kukhetsa madzi komanso kutsika kwamphamvu kwa pepala. Polyacrylamide amagwiritsidwa ntchito makamaka ngati dispersant, posungira thandizo, ngalande thandizo, flocculant, ndi sizing wothandizira pa papermaking ndondomeko.

Ⅰ. Wobalalitsa

Kuwonjezera polyacrylamide dispersant pa papermaking ndondomeko angathe kuteteza agglomeration ulusi ndi kusintha kufanana kwa pepala. Kuchulukitsa kocheperako kumatha kulimbikitsa kufalikira kwabwino kwa ulusi wopangira mapepala ndikukhala ndi zotsatira zabwino kwambiri zopanga mapepala. Ikhozanso kupititsa patsogolo kufanana kwa zamkati ndi kufewa kwa pepala, ndikuwonjezera mphamvu za pepala. Ndizoyenera pazinthu zosiyanasiyana zamapepala apanyumba monga mapepala akuchimbudzi, zopukutira, zomatira kumaso, ndi mapepala ena owonda. M'mafakitale ena a pepala, amatha kusinthanso Polyethylene Oxide (PEO).

Ⅱ. Thandizo Losunga

PAM imagwiritsidwa ntchito nthawi zambiri ngati chithandizo chosungirako mumakampani opanga mapepala kuti awonjezere kuchuluka kwa fiber ndikuchepetsa kutulutsa kwamadzi. Mfundo yake yogwirira ntchito ndi kupanga ma flocs akuluakulu okhala ndi tinthu tating'onoting'ono, tomwe timatha kuchotsedwa mosavuta kuchokera ku zamkati kudzera mu kusefera kapena matope.

Ⅲ. Thandizo la Ngalande

PAM itha kukhalanso ngati thandizo la ngalande popanga mapepala. Imawonjezera kuchuluka kwa ngalande, kupangitsa kuti madzi azitha mwachangu komanso moyenera pamapepala pamakina. Izi zimathandiza kuonjezera liwiro la kupanga ndi kuchepetsa mphamvu yogwiritsira ntchito mphamvu pofupikitsa nthawi yowuma yofunikira pa pepala.

Ⅳ. Sizing Agent

Nthawi zina, polyacrylamide imagwiritsidwa ntchito ngati choyezera pakupanga mapepala kuwongolera kulowa kwamadzi ndi zakumwa zina papepala. Izi zimathandiza kukwaniritsa zomwe mukufuna monga kukana madzi ndi inki yosungiramo inki, makamaka pamapulogalamu omwe pepala liyenera kupirira chinyezi kapena kusindikiza.

Ⅴ. Flocculant

Pa ndondomeko ya madzi onyansa mu mphero mapepala, Polyacrylamide angagwiritsidwe ntchito ngati flocculant kuchotsa inaimitsidwa zolimba ndi zoipitsa mu madzi oipa. Zimathandiza kupanga tinthu tating'onoting'ono totchedwa flocs, zomwe zimatha kuchotsedwa mosavuta kudzera mu sedimentation kapena kusefera. Izi zimathandizira kuchepetsa kuipitsidwa kwa madzi ndikuwongolera kukhazikika kwa chilengedwe cha bizinesi yopanga mapepala.

Ponseponse, mawonekedwe osunthika a polyacrylamide amapangitsa kuti ikhale chowonjezera chofunikira pamakampani opanga mapepala, zomwe zimathandizira kuti ntchitoyo ikhale yabwino, mtundu wazinthu, komanso magwiridwe antchito amapepala. Kugwiritsa ntchito polyacrylamide m'munda wopanga mapepala kumayambira pamakampani opanga mapepala, kuyambira kupanga mapepala kupita kumadzi onyansa. Sikuti amangowonjezera ubwino ndi kupanga bwino kwa mapepala, amachepetsa ndalama zopangira, komanso amathandiza kwambiri kuteteza chilengedwe.
