Yog vim li cas rau deterioration ntawm polyacrylamide thiab kev daws teeb meem:
Yog vim li cas ib tug: polyacrylamide raws li ib tug organic polymer thiab polymer, nrog ib tug zoo noob pab pawg neeg, vim muaj zog flocculation adsorption, yog hais tias lub Yin humid qhov chaw, nws yog ib qho yooj yim mus nqus noo noo thiab tsim ib tug thaiv, tshwj xeeb tshaj yog ib co nag lossis daus loj heev, huab cua ntub , tshwj xeeb tshaj yog yooj yim los ua metamorphism.
Kev daws: polyacrylamide cia hauv qhov txias dua li qhov chaw ntub dej, tib lub sijhawm sab hauv tsev yuav tsum muaj qee qhov cua, yog tias nws los nag yuav tsum tau kaw nruj me ntsis, luv luv, tsis txhob sib cuag nrog cov kua dej.
Yog vim li cas 2: Tom qab siv cov polyacrylamide, vim yog kev ua haujlwm tsis khoom, lub sijhawm tsis nco qab qhib lub hnab polyacrylamide los tuav dua, ua rau polyacrylamide nqus dej hauv huab cua thiab tsis zoo.
Kev daws: tsis muaj teeb meem thaum twg thiab qhov twg, tsuav yog qhib lub hnab ntim polyacrylamide, tam sim ntawd los qhwv, tsis txhob muab cua me ntsis, airtight zoo.
Yog vim li cas peb: lub txee lub neej ntawm polyacrylamide tas sij hawm, txawm hais tias kev siv ntawm polyacrylamide nws lub txee lub neej tsis zoo ib yam, tab sis lub sij hawm ntawm lub txee lub neej, nws yog tag nrho invalid.
Kev daws: Txhua yam khoom muaj qee qhov txee lub neej, ntxiv rau lub txee lub neej, ces txawm tias kev tiv thaiv kev tiv thaiv yuav tsum ua kom nruj dua, nws tsis pab, vim tias ntxiv rau qhov tseem ceeb ntawm qhov teeb meem, sab nraud ua raws li qhov cuam tshuam, nws pom zoo kom tsis txhob yuav polyacrylamide ntau dhau lawm, sai sai khiav tawm mus yuav, tsis txhob muab cov polyacrylamide mus sij hawm ntev.
Qhov laj thawj plaub: polyacrylamide tsis muaj teeb meem, tab sis tom qab kev teeb tsa ua tiav ntawm cov tshuaj polyacrylamide, ntau tshaj 24 teev, uas yog, hauv 24 teev tsis siv cov tshuaj polyacrylamide.
Kev daws: nruj me ntsis hais lus, tsuav yog qhov ua tiav kev teeb tsa ntawm cov tshuaj polyacrylamide, nws yuav tsum tau siv tam sim ntawd hauv ob peb teev, vim tias lub sijhawm cia tom qab kev teeb tsa ntawm cov tshuaj raug txwv, txwv tsis pub hydrolysis ntawm polyacrylamide cov tshuaj tiv thaiv tes rau qhov cuam tshuam, nws tau pom zoo siv hauv 24 teev.
Raws li cov kws tshaj lij kev tshawb fawb hais tias lub sijhawm zoo ntawm polyacrylamide yog 1 xyoo, yog tias ntau tshaj li lub sijhawm no, leej twg thov tuaj tsis muaj txiaj ntsig, tsis tsuas yog poob nyiaj txiag thiab khoom siv, thiab tseem tuaj yeem ncua lub sijhawm tsim kho.
Kev khaws cia ntawm polyacrylamide kom raug
Hnub tas sij hawm yog qhov xwm txheej ntawm tag nrho cov khoom, thiab tib yam muaj tseeb rau cov neeg ua haujlwm kho dej. Txawm hais tias nws yog khoom los yog kua, lub sij hawm tas sij hawm tau dhau mus, thiab kev pheej hmoo ntawm kev ua tsis tiav yog siab heev. Yog li cas koj qhia yog tias polyacrylamide ua tsis tiav?
Txog polyacrylamide, ntau hom polyacrylamide, lub sijhawm txee lub neej txawv. Qhov no muaj ntau yam ua rau nws cov qauv, lub sijhawm siv tau ntawm anionic polyacrylamide yog li 2 xyoos, lub txee lub neej ntawm cationic polyacrylamide yog 1 xyoos. Yog tias hnub tas sij hawm dhau mus, hnub tas sij hawm yuav raug tas sij hawm.
Qhov chaw cia ntawm polyacrylamide muaj kev cuam tshuam zoo rau nws lub neej txee. Lub txee lub neej ntawm polyacrylamide tuaj yeem txuas ntxiv rau hauv qhov cua, qhuav thiab qhov chaw txias. Nyob rau hauv qhov kub thiab txias ib puag ncig, polyacrylamide txee lub neej yog luv luv.
Hauv qee qhov chaw, vim muaj huab cua ntub, qee cov dej phwj tuaj ntawm polyacrylamide tsub zuj zuj rau lub sijhawm ntev, ntim lub qhov ncauj tsis muaj zog, hygrophilic caking, rau lub caking ntawm polyacrylamide flocculant, ntau tus neeg muaj lus nug txog seb nws puas siv tsis tau. Yog li ntawd, qhov tsis ua tiav ntawm polyacrylamide tuaj yeem txiav txim los ntawm ob yam. Ua ntej, qhov viscosity raug txo, thiab cov nyhuv flocculation tsis zoo thaum siv.
Txoj kev khaws cia kom raug ntawm polyacrylamide:
1, polyacrylamide cia, yuav tsum ua kom ib puag ncig kaw, qhuav, tsis txhob lub teeb, tiv thaiv kub, tsis txhob ya raws, decomposition thiab deterioration.
2, lub sij hawm cia ntawm polyacrylamide yuav tsum tsis txhob ntev dhau. Txwv tsis pub, nws yuav ua rau aging decomposition, feem ntau lub thinner lub concentration, lub sij hawm luv luv.
3, polyacrylamide flocculant thiab high hlau ions yog ib qho yooj yim los tsim insoluble gel, yog li nws yuav tsum tsis txhob muab cia rau hauv kev sib cuag nrog hlau ntim rau lub sij hawm ntev.
Yog li ntawd, peb tab tom hloov qhov chaw cia ntawm polyacrylamide. Qhov kub thiab txias yog qhov tseem ceeb. Qhov kub cia yuav tsum nruj me ntsis tswj hauv qab 50 degrees kom tsis txhob raug ncaj qha. Qhov thib ob, ib qho me me ntawm stabilizer tuaj yeem muab ntxiv rau cov tshuaj polyacrylamide, xws li sodium thiocyanate, thiurea, sodium nitrite thiab non-solvent methanol, ua kom cov tshuaj polyacrylamide ruaj khov.
