Tshuaj hmoov txheej ncua kev kawm ntawv PAM yog ib tug nrov khoom siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv. Ua tsaug rau nws qhov tshwj xeeb muaj pes tsawg leeg, cov hmoov txheej txheej tshem tawm zoo tiv thaiv kev tsim ntawm agglomeration hauv kev ncua. Qhov no, nyob rau hauv lem, tso cai rau txhim kho lub dispersion thiab stability ntawm ncua kev kawm ntawv nrog tsawg kawg nkaus kev sib hais haum.
Ib qho ntawm cov kev siv tseem ceeb ntawm PAM yog nyob rau hauv kev lag luam coatings. Tus neeg sawv cev yog siv los txhim kho qhov adhesion thiab durability ntawm coatings ntawm ntau qhov chaw. Tsis tas li ntawd, nws yog ib qho tseem ceeb muaj nyob rau hauv kev tsim cov xim zoo nkauj, adhesives thiab inks. Kev suav nrog PAM hauv cov khoom lag luam no muaj txiaj ntsig zoo hauv kev txhim kho lawv cov kev ua tau zoo thiab txhim kho lawv qhov zoo tag nrho.
PAM kuj tseem siv rau hauv kev lag luam ntawv thiab cov ntaub so ntswg, qhov twg nws ua raws li cov khoom khaws cia. Tus neeg sawv cev pab txhim kho kev khaws cia ntawm cov fillers thiab lwm yam khoom ntxiv thaum lub sijhawm tsim khoom, yog li txo cov nqi tsim khoom tag nrho. PAM kuj tseem pab txhim kho lub zog thiab dej tsis kam ntawm daim ntawv, ua kom nws lub neej ntev thiab kav ntev.
Tsis tas li ntawd, PAM yog siv los ua flocculant hauv kev kho dej khib nyiab. Nrog nws qhov hnyav molecular hnyav thiab tus nqi anionic, tus neeg sawv cev zoo nyiam cov khoom tshem tawm hauv cov dej khib nyiab thiab khi rau cov khoom loj dua, hnyav dua sib sau ua ke thiab yooj yim tshem tawm. Cov txheej txheem no, hu ua flocculation, yog ib kauj ruam tseem ceeb hauv kev kho cov dej khib nyiab kom tshem tawm cov kab mob tsis zoo ua ntej lawv tawm mus rau ib puag ncig.
