I-Polyacrylamide (PAM) kunye nokusetyenziswa kwayo kunyango lwamanzi

Ulawulo longcoliseko lwamanzi kunye nolawulo luyinxalenye ebalulekileyo yokhuseleko lokusingqongileyo kunye nokulahlwa kwamanzi amdaka.

I-Polyacrylamide (PAM), i-polymer enyibilikayo emanzini ethe ngqo, inendima ebaluleke kakhulu kwicandelo lokunyanga amanzi ngenxa yobunzima obukhulu beemolekyuli, ukunyibilika emanzini, ukulawulwa kobunzima beemolekyuli kunye nokuguqulwa okuhlukeneyo kokusebenza.

I-PAM kunye nezinto eziphuma kuyo zingasetyenziswa njenge-flocculants ezisebenzayo, i-agent yokuqinisa, i-agent yokunciphisa ukutsalwa, esetyenziswa kakhulu ekucutshungulweni kwamanzi, ekwenzeni amaphepha, kwi-petroleum, kumalahle, kwi-geology, ekwakheni nakwamanye amacandelo emizi-mveliso.

Kumanzi angaphantsi komhlaba, emanzini angaphezulu namanzi amdaka, ukungcola kunye nokungcola kuhlala kukho amasuntswana amaninzi amancinci kakhulu ukuba angahlala phantsi komxhuzulane. Ngenxa yokuba ukutsalwa kwendalo akukwazanga ukuhlangabezana neemfuno, ngoncedo lweekhemikhali, iteknoloji iyasebenza ekuveliseni. Umzekelo, imolekyuli ye-PAM ifunxa amasuntswana amaninzi kwaye yenze i-floc enkulu, ngoko ke, ukuhlaliswa kwamasuntswana kuyakhawuleziswa.

Xa kuthelekiswa ne-flocculant engaphiliyo, i-PAM ineenzuzo ezininzi ezibalulekileyo: iintlobo ezininzi zeemeko ezahlukeneyo, ukusebenza kakuhle, idosi encinci, ukungcola okuncinci okuveliswayo, kulula emva konyango. Oku kuyenza ibe yeyona flocculant ifanelekileyo.

Imalunga nomthamo we-inorganic coagulant ukusuka kwi-1/30 ukuya kwi-1/200.

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

I-PAM yomgubo kulula ukuyithutha, kodwa ayilula ukuyisebenzisa (kufuneka izixhobo zokunyibilikisa), ngelixa i-emulsion ilula ukuyithutha kwaye inobomi obufutshane bokugcina.

I-PAM inokunyibilika okukhulu emanzini, kodwa inyibilika kancinci kakhulu. Ukunyibilika kubiza iiyure ezininzi okanye ubusuku bonke. Ukuxuba kakuhle ngomatshini kuya kunceda ukunyibilikisa i-PAM. Soloko ufaka i-PAM kancinci emanzini axutyiweyo - hayi amanzi kwi-PAM.

Ukufudumeza kunokunyusa kancinci izinga lokunyibilika, kodwa ubushushu akufuneki budlule kwi-60°C.

Uxinzelelo oluphezulu lwe-PAM kwisisombululo se-polymer yi-0.5%, uxinzelelo lwe-PAM ye-molecular ephantsi lunokulungiswa lube yi-1% okanye ngaphezulu kancinci.

Isisombululo se-PAM esilungisiweyo kufuneka sisetyenziswe kwiintsuku ezimbalwa, kungenjalo ukusebenza kwe-flocculation kuya kuphazamiseka.
