Polyacrylamide (Pam)Ua si lub luag haujlwm tseem ceeb hauv kev lag luam qab zib los ntawm kev txhim kho kev ua haujlwm ntawm cov piam thaj. Raws li kev sib txuam flocculant, PAM yog qhov tseem ceeb tshaj plaws rau cov kua txiv kom meej, ua kom zoo dua cov txheej txheem, thiab txhim kho cov paib. Tsab ntawv no tshawb nrhiav lub luag haujlwm ntawm Pam, tshwj xeeb tshaj yog anionic pam, nyob rau hauv cov txheej xwm ntau lawm, thiab nws qhov tseem ceeb hauv kev tswj kom siab- nplej zom zom.
Lub Suab Qab Zib Raug
Kev tsim cov piam thaj los ntawm cov piam thaj lossis qab zib beet cuam tshuam ntau theem, suav nrog:
Sau qoob loo: suab thaj lossis qab zib beet yog sau los ntawm liaj teb thiab thauj los ua cov nroj tsuag. Nws yuav tsum raug sau tseg tias cov kab muaj sia liab tsis tuaj yeem siv los ua qab zib.
Pob zeb tsoo: cov khoom siv raw yog crushed rau extract kua txiv, tawm hauv qab fibrous bagasse raws li byproduc.
Cov kua txiv rho tawm: cov kua txiv rho tawm yog cov dej sib xyaw nrog dej thiab lim kom tshem tawm cov khoom loj.
Cov ntsiab lus meej: Nyob rau theem no, PAM FLOCC tau ntxiv rau tshem tawm cov ntawv raug tshem tawm zoo thiab tsis txaus los ntawm cov kua txiv.
Evaporation: Cov kua txiv kom pom tseeb yog rhaub kom yaj cov dej ntau dhau, ua cov photrated syrup.
Crystallization: lub syrup yog txuas ntxiv los ua cov suab thaj muaju.
Kom qhuav & ntim khoom: cov suab thaj ua kom qhuav, ua kom zoo, thiab ntim rau kev faib tawm.
Ntawm cov theem no, meej yog qhov twg polyacrylamide tuaj rau hauv kev ua si.
* Hais meej thiab lub luag haujlwm ntawm polyacrylamide
Thaum lub ntsiab lus meej, cov kua txiv nyoos muaj impurities xws li hmoov zoo, fibers, thiab tshem tawm cov khib nyiab. Cov impurities yuav tsum tau muab tshem tawm kom muab cov kua txiv ntshiab, uas yog qhov tseem ceeb rau high- rab txob qab zib zoo. PamFlocculants, tshwj xeeb anionic pam, tau ntxiv rau cov kua txiv rau cov neeg raug tshem tawm, ua kom muaj cov flocs loj dua los ntawm kev ua kom yooj yim los ntawm kev ua kom pom tseeb lossis pom.
Vim li cas siv PAM Flotighants nyob rau hauv qab zib ntau lawm
{{0 {}} txhim kho kom pom tseeb
Pam flocculants txhim kho cov sedimentation ntawm cov khib nyiab, ua rau cov kua txiv sai dua thiab ntshiab. Qhov no ua kom pom tseeb tias kev hloov pauv thiab cov theem siv crystallization ua tiav tsis muaj kev paug.
{{0- tus nqi -} ua hauj lwm zoo
Siv polyacrylamide nyob rau hauv qab zib manufacturing txo qhov kev xav tau rau lwm cov lus qhuab qhia. Kev txhim kho kev ua tau zoo kuj tseem nkim, ua rau cov nqi txuag tau nyiaj.
{{0 {}} cov qauv kev nyab xeeb thiab kev nyab xeeb
Pam siv hauv kev lag luam qab zib yog zaub mov - qib thiab ua raws li nws tsis cuam tshuam rau qhov zoo lossis kev nyab xeeb ntawm cov khoom qab zib kawg.
- Kev pab ib puag ncig ib puag ncig
Pam pab txo kev siv dej hauv qab zib los ntawm kev txhim kho cov kev ua kom pom tseeb thiab rov ua dua cov txheej txheem dej. Nws ua tau zoo kuj tseem txo cov tshuaj pov tseg, pab txhawb kom muaj kev ua haujlwm ntau.
Cov yam ntxwv ntawm Anionic Pam rau kev lag luam qab zib
-} siab molecular hnyav
Anionic Pam nrog lub cev hnyav dua muab cov bridging zoo tshaj plaws ntawm cov ntsiab lus, ua kom yooj yim dua cov sedimentation.
- Txheem Kev Tiv Thaiv Iionic
Cov qib ntawm anionic tus nqi tuaj yeem hloov kho kom haum kom haum cov kua txiv tshwj xeeb, ua rau nws ntau yam rau ntau qhov chaw ntau lawm.Aquaenjoy, raws li kev kho mob dej kev ua haujlwm, tuaj yeem muab cov kev pabcuam customized.
-} muaj zog froc tsim
Pam flocculants tsim cov flocs uas tiv thaiv txhua yam kev ntxhov siab thaum lub sijhawm ua haujlwm lossis sib cais.

Hauv cov ntsiab lus, polyacrylamide tau dhau los ua kev tsis tseem ceeb hauv kev lag luam qab zib. Nws lub peev xwm los txhim kho cov kev qhia meej, txhim kho cov txheej txheem ua haujlwm, thiab txo cov nqi ua rau nws xaiv qhov kev xaiv qab zib zoo tshaj plaws.Yog xav paub ntxiv txog Pam flocculants thiab lawv cov ntawv thov, tiv tauj peb kom tshawb peb cov kev daws teeb meem!
