The mankhwala kusinthidwa wa Polyacrylamide ntchito posungira ndi ngalande zothandizira mu papermaking zambiri kusinthidwa mankhwala a polyacrylamide, kuphatikizapo anionic polyacrylamide (APAM), cationic Polyacrylamide (CPAM) ndi amphoteric Polyacrylamide (AmPAM), ndi wachibale maselo misa 2 miliyoni ~ 4 miliyoni. .
Nthawi zambiri, APAM imapanga dongosolo lovuta lomwe lili ndi zinthu zina za cationic kuti zithandizire kwambiri posungira.Mwachitsanzo, kuphatikiza ndi aluminiyamu sulphate kungapangitse kuti APAM ikhale yogwirizana kwambiri ndi ulusi, ulusi wabwino, zodzaza, ndi zina zotero, potero zimasintha kwambiri kusungidwa kwa ulusi wabwino ndi zodzaza.Mlingo wa chidwi.
CPAM ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri posungira popanga mapepala, ndipo zinthu zolemera kwambiri zamamolekyu komanso kachulukidwe kakang'ono zimagwiritsidwa ntchito.mlandu wake ndi wotsutsana ndi CHIKWANGWANI, ndipo angagwiritsidwe ntchito yekha kapena osakaniza bentonite, anion, etc., chifukwa flocculation pepala ndi bridging limagwirira mu pepala zakuthupi, ndipo akhoza kuonjezera mlingo posungira wa pepala filler ndi kulimbikitsa Kuchuluka kwa madzi oyera pansi pa ukonde kumachepetsedwa.Pamene CPAM ndi zoipa mlandu bentonite ntchito kupanga particulate posungira ndi ngalande thandizo dongosolo, kukula kwa flocs wa zinthu pepala aumbike powonjezera CPAM ndi lalikulu, ndipo pambuyo kugonjetsedwa ndi mkulu kukameta ubweya mphamvu pambuyo kudutsa zamkati mpope ndi. zipangizo zina, flocs anathyoledwa mu tiziduswa tating'ono, ndipo kuwonjezera zoipa mlandu bentonite pa nthawi ino adzabwezeretsanso mlatho tizidutswa tating'onoting'ono ndi kupanga flocs ang'onoang'ono kuposa flocs poyamba anapanga CPAM.Potero, kasungidwe kazinthu zamapepala kamakhala bwino, ndipo kagwiridwe kake ka pepala kamakhala bwino.
Pamene AMPAM imagwiritsidwa ntchito ngati chithandizo chosungira ndi madzi, magulu a anionic amachotsa zinyalala za anionic mu zamkati, ndipo magulu a cationic amaphatikizana ndi ulusi ndi ulusi wabwino.Chifukwa chake, kusungidwa kwa ulusi wabwino kumakula bwino.
