Polyacrylamide (PAM) yog cov khoom siv dav siv polymer hauv kev lag luam textile vim nws cov kev siv ntau yam thiab cov txiaj ntsig. Hauv tsab ntawv no, peb yuav tshawb nrhiav kev siv polyacrylamide hauv kev lag luam textile.
- PAM feem ntau yog siv los ua flocculant hauv cov txheej txheem kho dej khib nyiab hauv cov chaw tsim khoom.
Kev tsim khoom siv textile suav nrog ntau yam txheej txheem tshuaj lom neeg uas tsim cov dej khib nyiab ntau uas muaj cov khib nyiab pov tseg thiab dyes. Polyacrylamide tuaj yeem khi cov khoom no ua ke, tsim cov flocs loj dua uas yooj yim dua thaum lub sij hawm sedimentation lossis pom cov txheej txheem. Qhov no pab txhim kho cov dej zoo thiab txo cov pa phem ib puag ncig los ntawm kev tsim textile.
- PAM tuaj yeem siv los ua tus neeg sawv cev sizing hauv kev tsim cov ntaub.
Sizing tus neeg sawv cev yog siv rau yarns ua ntej weaving los yog knitting los txhim kho lawv lub zog, smoothness, thiab tsis kam mus abrasion thaum lub sij hawm ua cov kauj ruam tom ntej xws li dyeing los yog xov. Polyacrylamide-based sizing agents muab cov khoom ua yeeb yaj kiab zoo heev, ua rau kev txhim kho ntaub thiab ua haujlwm ntev.
- PAM pom daim ntawv thov ua cov khoom tawg rau cov txheej txheem dyeing hauv kev lag luam textile.
Dye molecules zoo li agglomerate thaum ntxiv ncaj qha rau hauv dye da dej, ua rau cov xim tsis sib xws ntawm cov ntaub. Los ntawm kev ntxiv polyacrylamide-raws li dispersants rau hauv cov dye da dej, nws pab tiv thaiv clumping ntawm dye molecules thiab xyuas kom meej xim xim nkag mus rau hauv cov ntaub ntaub.
- PAM tuaj yeem ua raws li tus neeg sawv cev thickening rau luam ntawv pastes siv hauv textile luam ntawv ua haujlwm.
Printing pastes muaj cov pigments dispersed nyob rau hauv cov kua nruab nrab uas xav tau viscosity tsim nyog rau daim ntawv thov mus rau fabrics los ntawm kev tshuaj ntsuam los yog cov menyuam txoj kev. Qhov sib ntxiv ntawm PAM ua rau kom cov viscosity ntawm luam ntawv pastes tsis cuam tshuam rau lawv cov kev ruaj ntseg lossis xim siv.
Hauv kev xaus, polyacrylamide ua lub luag haujlwm tseem ceeb hauv ntau yam ntawm kev lag luam textile suav nrog kev kho dej khib nyiab, cov neeg ua haujlwm loj rau kev tsim cov ntaub, dispersants rau cov txheej txheem dyeing, thiab thickening agents rau luam ntawv pastes. Nws cov khoom siv ntau yam ua rau nws yog ib qho tseem ceeb ntawm kev ua haujlwm rau kev txhim kho kev ua tau zoo, kev ua tau zoo, thiab kev ruaj khov hauv cov haujlwm no.
