Qalabka Polyacrylamide

Polyacrylamide emulsion waxaa lagu diyaariyaa iyadoo la kala firdhinayo ama polymerization emulsion la soo celinayo, taas oo ah nooc dareere polyacrylamide ah oo jira. Marka laga reebo astaamaha polyacrylamide adag ee flocculants, iyada oo loo marayo silsiladda molecule ee kooxaha polar si ay u nuugiso qalabka adag ee la joojiyay ee qaybaha biyaha, emulsion waxay qaabeyn kartaa qaybaha waaweyn iyada oo loo marayo buurta u dhexeeya qaybaha ama korontada.

Polyacrylamide emulsion waxaa lagu qaybiyaa laba nooc, biyaha saliida, iyo biyaha biyaha. Ka duwan buudaha polyacrylamide, habka qalajinta ma loo baahan yahay habka wax soo saarka polyacrylamide nooca emulsion. Sidaa darteed, polyacrylamide emulsions miisaanka molekulka iyo biyaha lagu daro ayaa ka sarreeya miisaanka molekulka polyacrylamide ee isku mid ah. Biyaha ku jira saliida waxaa caadi ahaan biyo aan lagu xalin karin. Sidaa darteed, geedi socodka wax soo saarka polyacrylamide nooca emulsion, ama isticmaalka emulsion ka hor inta lagu dhaliyo geedi socodka dilution, baahida in lagu daro hydrophilic surfactant, si marka nooca emulsion ee biyaha dib u eego marxaladda, si emulsion lagu dhali karo biyaha. Laakiin biyaha biyaha ku jira waa mid aad u fudud in lagu dhaliyo, sidoo kale habka isku dhafka waa mid horumarsan. Ku xaliyo emulsion biyo si aad u isticmaasho xawaaraha sare ee shear marka wadada, si emulsion ee polyacrylamide hydrogel si buuxda ula xiriir biyo iyo si degdeg ah u kala firdhay biyaha. Haddii emulsion iyo biyaha si buuxda u xiriiri karaan kala firdhinta, waqtiga lagu dhaliyo guud ahaan waa kaliya 3-15 daqiiqo. Heerkulka kaydinta ee emulsion wuxuu ugu fiican yahay u dhexeeya 0 iyo 30 ° C, celceliska emulsion waxaa lagu kaydiyaa 6 bilood. Heerkulka qaboojinta emulsion waa ka hooseeya biyaha. Emulsion qaboojiyey ayaa sii wadi kara isticmaalka ka dib dhalaalka, waxqabadkeedu si weyn uma beddeli doono. Polyacrylamide granular waxaa sameeyaa AM (acrylamide) monomer polymerization colloid, burburinta iyo qalajinta kadibna la heli karo. Waxaa jira dhibaatooyin badan oo loogu talagalay buudada polyacrylamide, sida soo saarista boodh aad u badan, burburinta waxyeello silsilad molecule, qalajinta, isticmaalka isku dhaliyaha si loo xaliyo (wax badan oo waqti iyo isticmaalka tamarta ah), laakiin polyacrylamide qaybaha ugu weyn waa fudud in la gaadiido iyo kaydinta.

Marka lagu daro faa'iidooyinka polyacrylamide adag, flocculants emulsion sidoo kale waxay leeyihiin faa'iidooyin gaar ah sida xulashooyin weyn oo xiisaha ah, xawaaraha burburka, isticmaalka tamarta hooseeya, kaydinta iyo si fudud loo isticmaalo iyo wixii la mid ah. Marka la barbar dhigo alaabta caadiga ah ee polyacrylamide cationic, emulsion polyacrylamide oo loogu talagalay noocyo ballaaran oo qiimo PH ah, xasilloonida xiisaha sare, saameynta flo Sidoo kale waxay ku habboon yihiin goobaha dhismaha oo aan lahayn qalab weyn oo lagu rakibay.

Polyacrylamide emulsion waxaa si ballaaran loogu isticmaalaa biyaha wasakhda ee guriga, biyaha wasakhda kiimikada ah, biyaha wasakhda ee goobta saliida, biyaha wasakhda, warqadda iyo goobaha kale. Polyacrylamide biyo-saliid emulsion ayaa sidoo kale si ballaaran loogu isticmaalaa daaweynta biyaha wasakhda ee magaalooyinka, warshadaha beer, warshadaha starch, warshadaha cuntada iyo daaweynta kale ee biyaha wasakhda. Ka saarida flocculation ee qalabka adag ee dabiiciga ah ee ku jira biyaha caafimaadka ah ama caafimaadka ah ayaa si gaar ah loogu talagalay. Warshadaha warqadda, waxaa loo isticmaali karaa sidii shaandhig caawimaad ah oo la ilaaliyo, daaweynta biyaha wasakhda ah ee warqadda. Warshadaha saliida waxaa loo isticmaali karaa wakiilka daboolka emulsion ee qodista ama wakiilka dhirta.
