Polyacrylamide (PAM), alias: flocculant, anion, cation,
polymer; Polymers, khaws cia thiab pom AIDS, khaws cia AIDS, dispersants; Polymer, oil displacement agent, thiab lwm yam.
Cov yam ntxwv cuam tshuam rau kev siv dej phwj tuaj:
1. Sludge yog ib yam khoom uas tsis muaj kev kho dej phwj tuaj. Ua ntej ntawm tag nrho cov, peb yuav tsum to taub lub hauv paus, xwm, muaj pes tsawg leeg thiab cov ntsiab lus ntawm sludge. Raws li cov ntsiab lus tseem ceeb ntawm sludge, sludge tuaj yeem muab faib ua cov organic sludge thiab inorganic sludge. Feem ntau hais lus, cationic polyacrylamide yog siv rau kev kho mob ntawm cov organic sludge, anionic polyacrylamide yog siv rau kev kho mob ntawm inorganic sludge. Nws tsis yooj yim rau siv cationic polyacrylamide thaum cov alkaline muaj zog heev, thiab nws tsis tsim nyog siv anionic polyacrylamide thaum cov ntsiab lus ntawm sludge siab.
2. Ion degree xaiv: rau cov sludge kom lub cev qhuav dej, flocculant nrog txawv ion degree tuaj yeem soj ntsuam los ntawm kev sim me me los xaiv cov polyacrylamide uas tsim nyog, kom nws tuaj yeem ua tiav cov nyhuv flocculant zoo dua, tab sis kuj tuaj yeem ua kom tsawg kawg nkaus, txuag nqi.
3. Qhov loj ntawm flocs: flocs me me heev yuav cuam tshuam rau kev ceev ntawm cov kua dej, flocs dhau los ua ke rau flocs khi dej ntau thiab txo cov av nkos biscuit degree. Qhov loj ntawm flocs tuaj yeem hloov kho los ntawm kev xaiv qhov hnyav molecular ntawm polyacrylamide.
4. Lub zog ntawm flocs: flocs yuav tsum nyob ruaj khov thiab tsis tawg nyob rau hauv qhov kev txiav txim ntawm shear. Ua kom qhov hnyav molecular ntawm polyacrylamide los yog xaiv cov qauv molecular tsim nyog yuav pab tau kom muaj kev ruaj ntseg ntawm flocs.
5. Kev sib xyaw ntawm polyacrylamide thiab sludge: polyacrylamide nyob rau hauv ib qho chaw ntawm cov khoom siv lub cev qhuav dej yuav tsum tau ua kom tiav nrog sludge, flocculation. Yog li ntawd, cov viscosity ntawm cov tshuaj polyacrylamide yuav tsum tsim nyog, thiab nws tuaj yeem sib xyaw nrog cov sludge nyob rau hauv cov khoom siv uas twb muaj lawm. Txawm hais tias ob qho tib si sib xyaw ua ke yog qhov tseem ceeb rau kev vam meej. Lub viscosity ntawm cationic polyacrylamide kua muaj feem xyuam rau nws qhov hnyav molecular thiab kev npaj concentration.
6. Lub dissolution ntawm cationic polyacrylamide: yaj zoo kom muab tag nrho ua si rau flocculation. Qee lub sij hawm nws yog ib qho tsim nyog yuav tsum ua kom nrawm nrawm nrawm, thaum cov ntsiab lus ntawm cov tshuaj polyacrylamide tuaj yeem txiav txim siab.
