Ndikhetha njani uhlobo lwePolyacyrrylam?

I-polyacybuslam. Isetyenziselwa ikakhulu ukubhalwa kunyango lwamanzi. Xa ukhetha, iintlobo ezahlukeneyo zamanzi amdaka anokukhetha iintlobo ezahlukeneyo. Kuya kufuneka ukhethe i-pim elungileyo ngokweempawu zotywala wakho. Kwangelo xesha, kuya kufuneka ucace gca apho inkqubo ye-polyacrylam iya kongezwa kwaye injongo ofuna ukuyiphumeza ngokuyisebenzisa.

Izalathi zezobuchwephesha zePolyacyrysam

I-1. Ubunzima bemolekyuli / i-viscosity

I-POLYACSTRYEDALY ineentlobo ngeentlobo zemilinganiselo yemolekyuli, ukusuka ezantsi ukuya phezulu kakhulu. Ubunzima bemolekyuli buchaphazela ukusebenza kwee-polymers kwizicelo ezahlukeneyo. I-polyacyracrylackas ephezulu yemolekyuli ihlala isebenza ngakumbi kwinkqubo yokuhlanjwa ngenxa yokuba imixokelelwane yabo yePolymere ide kwaye inokuqhagamshela amasuntswana amaninzi.

I-viscosity yesisombululo se-PAM iphezulu kakhulu. Xa i-ionsus izinzile, enkulu ubunzima bemoyari ye-polyacyrylamide, kokukhona viskosity yesisombululo. Kungenxa yokuba i-macromoralecular thein ye-polyacyrnide ide kwaye incinci, kwaye ukuxhathisa kwintshukumo kwisisombululo kuyinto enkulu kakhulu.

I-2. Inqanaba le-hydrolysis kunye ne-ionicy

I-ingonity ye-PAM inefuthe elikhulu kwiziphumo zalo zokusetyenziswa, kodwa ixabiso elifanelekileyo lixhomekeke kuhlobo kunye nohlobo lwezinto eziphathwayo, kwaye kukho amaxabiso ahlukeneyo ahlukeneyo kwiimeko ezahlukeneyo. Xa amandla e-ionic yezinto eziphathwayo iphezulu (i-Inorganic yezinto ezingaphezulu), i-ingonity ye-PAM isetyenzisiwe kufuneka iphakame, kungenjalo kufanele ukuba ibe sezantsi. Ngokubanzi, inqanaba le-anaion libizwa ngokuba yi-hydrolysis, kwaye inqanaba le-ion libizwa ngokuba yinqanaba le-cition.

Ungayikhetha njani iPolyacToryolamkuxhomekeke kuxinzelelo lweecolloids kwaye zinqunyanyisiwe emanzini. Emva kokuqonda ezi zikhombisi zingasentla, indlela yokukhetha i-pam efanelekileyo?

1. Qonda umthombo wokuntywila

Okokuqala, kufuneka siwuqonde umthombo, ubume, ukwakheka, umxholo oqinileyo, njl njl. Ye-Sludge.

Ngokubanzi, i-cudic polyacyriade isetyenziselwa ukuphatha i-Sludge ye-Ordluc, kwaye i-anaon Polyacysarackade isetyenziselwa ukuphatha isambuku. Xa i-PH iphakamileyo, i-cudic polyacyracylayide ayifanele isetyenziswe, kwaye nini, i-anaion polyacysaracyside akufuneki isetyenziswe. I-acidity eyomeleleyo yenza ukuba ingafanelekanga ukuba isebenzise i-anion polyacrysasside. Xa umxholo oqinileyo we-sludge uphakame, inani le-polyacyrnide ilukhulu.

2. Ukukhetha i-ionicy

I-sludge ekufuneka ikhutshiwe ngonyango oluhlaza, unokukhetha i-ionictions eyahlukileyo ngovavanyo oluncinci lokukhetha eyona nto ifanelekileyo ye-polyaczrylamide, enokuyifumana i-dosage, indleko.

3. Ukukhetha ubunzima bemolekyuli

Ngokubanzi, ukuphakamisa ubunzima beemolekyuli zePolyacyrylamide, okukhulu, kodwa kusetyenziswa, ukuphakama kobunzima bemveliso, okungcono ukusetyenziswa. Ngokusetyenziswa okuthile, ubunzima obufanelekileyo bemolekyuli ye-polyacrylamide kufuneka bugqitywe ngokommiselo wesicelo, umgangatho wamanzi kunye nezixhobo zonyango.

Xa uthenga kwaye usebenzise i-pam okokuqala, kuyacetyiswa ukuba unikezele ngemeko ethile yokuntywila kumvelisi we-floccuwst, kwaye siya kucebisa uhlobo olufanelekileyo lwemveliso. Kunye neesampulu zeposi zovavanyo. Ukuba unawo amava amaninzi kunyango lwakho lokuntywila, ungasixelela iimfuno zakho ze-loge, ungasixelela iimfuno zakho, amasimi esetyenziswayo, kunye neenkqubo, okanye usinike ngokuthe ngqo iisampulu zePAM ngoku, kwaye siya kukuthembisa ngePolyaczrylamide yasekunene.
