I-Polyacrylamide (PAM) kunye nesicelo sayo kuNyango lwaManzi

I-Polyacrylamide (PAM) kunye nokusetyenziswa kwayo kunyango lwamanzi

Ulawulo longcoliseko lwamanzi kunye nolawulo yinxalenye ebalulekileyo yokhuseleko lokusingqongileyo kunye nokulahlwa kokucocwa kwamanzi amdaka ahlawulelwe ngakumbi nangakumbi.

I-Polyacrylamide (PAM), i-polymer e-soluble yamanzi emgca, ibaluleke kakhulu kwintsimi yonyango lwamanzi ngenxa yobunzima be-molecular, i-soluble yamanzi, ukulawulwa kobunzima be-molecular kunye nokuguqulwa kwezinto ezahlukeneyo zokusebenza.

I-PAM kunye ne-derivatives yayo ingasetyenziselwa njenge-flocculants esebenzayo, i-ejenti yokuqina, i-ejenti yokunciphisa i-drag, isetyenziswe ngokubanzi ekuqhutyweni kwamanzi, ukwenza iphepha, i-petroleum, amalahle, i-geology, ukwakhiwa kunye namanye amacandelo oshishino.

Kumanzi aphantsi komhlaba, kumanzi angaphezulu kunye nogutyulo, ukungcola kunye nezingcolisi zidla ngokubakho njengamasuntswana amaninzi amancinane kakhulu ukuba angahlala phantsi komxhuzulane.Ngenxa yokuba i-sedimentation yendalo ayikwazanga ukuhlangabezana neemfuno, ngoncedo lweekhemikhali ukukhawuleza ukuhlaliswa kweteknoloji isetyenziswe kwimveliso.Umzekelo, imolekyuli yePAM ifunxa kumasuntswana amaninzi kwaye yenze ifloc enkulu, ke ngoko, ukuhlaliswa kwamasuntswana kuyakhawuleza.

Xa kuthelekiswa ne-inorganic flocculant, i-PAM ineengenelo ezininzi ezibalulekileyo: iinguqulelo ezininzi zeemeko ezahlukeneyo, ukusebenza kakuhle okuphezulu, idosi encinci, i-sludge encinci eyenziwe, lula emva kokunyanga.Oku kuyenza ibe yeyona flocculant ifanelekileyo.

Kumalunga nedosi ye-inorganic coagulant 1/30 ukuya kwi-1/200.

I-PAM ithengiswa ngeendlela ezimbini eziphambili: umgubo kunye ne-emulsion.

I-powder PAM kulula ukuyihambisa, kodwa akulula ukuyisebenzisa (izixhobo zokuchithwa zifunekayo), ngelixa i-emulsion ayilula ukuyihambisa kwaye inobomi obufutshane bokugcina.

I-PAM inokunyibilika okukhulu emanzini, kodwa inyibilika kancinane kakhulu.Ukuchithwa kubiza iiyure ezininzi okanye ubusuku bonke.Ukuxuba okulungileyo komatshini kuya kunceda ukunyibilikisa i-PAM.Soloko wongeza kancinane iPAM kumanzi axutyiweyo - hayi amanzi kwiPAM.

Ukufudumeza kunokunyusa kancinane izinga lokunyibilika, kodwa ubushushu akufunekanga budlule kuma-60°C.

I-PAM yoxinaniso oluphezulu lwesisombululo se-polymer yi-0.5%, i-concentration ye-PAM ephantsi ye-molecular inokulungiswa kwi-1% okanye iphakamileyo encinci.

Isisombululo sePAM esilungisiweyo kufuneka sisetyenziswe kwiintsuku ezininzi, ngaphandle koko ukusebenza kwe-flocculation kuya kuchaphazeleka.
