Acrylamide plays lub luag haujlwm tseem ceeb hauv kev kho dej, feem ntau los ntawm nws cov derivative polyacrylamide:

Tshem tawm impurities
Tsim flocculants: Acrylamide 99.9% Kev Kho Dej yog lub monomer rau kev tsim cov polyacrylamide (PAM), uas yog ib qho zoo heev flocculant thiab siv tau los tshem tawm cov khib nyiab, colloids thiab roj los ntawm dej, thiab lwm yam. Nws qhov hnyav molecular ua rau nws yog ib qho tseem ceeb flocculant siv hauv cov dej phwj tuaj thiab siv tau los tshem tawm cov khib nyiab, colloids thiab roj los ntawm dej, thiab lwm yam. Acrylamide thiab nws cov derivatives ua lub luag haujlwm tseem ceeb hauv thaj chaw xws li kev kho dej khib nyiab, kev lim dej haus, thiab dej hiav txwv desalination.
Txo turbidity: Hauv kev kho cov dej tsawg -turbidity, qhov feem ntawm cov organic teeb meem nyob rau hauv qis - kub thiab qis - turbidity dej kuj loj. Thaum tsuas yog flocculants xws li txhuas sulfate los yog PAC ntxiv, qhov turbidity ntawm lub supernatant yuav zoo li nce tom qab ncav cuag ib tug nqi, thiab cov tsim flocs yuav muaj ib tug xoob qauv, lub teeb thiab ntab, thiab yuav nyuaj rau khom, ua rau cov kev kho mob tsis zoo. After adding PAM as a coagulant aid, the volume of flocs increases, the density rises, the sedimentation rate accelerates, the sedimentation capacity rapidly improves, and the turbidity of the effluent significantly decreases. Ntxiv PAC nrog rau ntau qhov sib txawv ntawm PAM rau coagulation thiab sedimentation tuaj yeem ua kom nrawm nrawm nrawm. Thaum cov koob tshuaj ntawm PAM nce mus txog 0.03mg / L, lub sij hawm sedimentation tuaj yeem luv luv los ntawm ib nrab thiab qhov ntau npaum ntawm PAC tuaj yeem txo los ntawm 22%. Tsis tas li ntawd, qhov sib ntxiv ntawm PAM tuaj yeem ua rau cov khoom siv lim dej kom ua kom cov dej ntim ntau ntxiv thaum ua kom cov dej zoo thaum ua haujlwm dhau, txhim kho kev siv cov khoom siv thiab txo cov nqi.
Sludge dewatering
Cationic polyacrylamide feem ntau yog siv hauv sludge dewatering thiab huab cua flotation thiab lwm yam kev kho mob. Polyacrylamide muaj qhov hnyav molecular hnyav heev, uas ua rau cov kev sib txuas thiab kev cuam tshuam muaj zog. Nws tuaj yeem tsim cov flocs loj dua, thiab cov sedimentation ceev ntawm flocs yog sai dua, txo lub sij hawm sedimentation thiab ua kom zoo dua rau sludge dewatering.

Txhim kho dej kom zoo
Txo qhov ntau npaum li cas ntawm flocculants: Nyob rau hauv lub ntsiab lus ntawm kev ua tiav cov dej zoo tib yam, thaum PAM siv nrog rau lwm cov inorganic flocculants, qhov ntau npaum ntawm flocculants tuaj yeem txo qis.
