Ngilukhetha kanjani uhlobo lwe-polyyacrylamide?

Polycrylamide(UPam) ngokuvamile angahlelwa nge-anionic, i-cationic, ne-nonion ngohlobo lwe-Ion. Isetshenziselwa ikakhulukazi i-floccution ekwelashweni kwamanzi. Lapho ukhetha, izinhlobo ezahlukene zamanzi amdaka angakhetha izinhlobo ezahlukene. Udinga ukukhetha i-pam efanele ngokwezimpawu zokukhucululwa kwendle yakho. Ngasikhathi sinye, kufanele futhi ucacise ukuthi i-polycacide izongezwa yiphi inqubo futhi nenhloso ofuna ukuyifinyelela ngokuyisebenzisa.

Izinkomba zezobuchwepheshe zePolayirylamide ngokuvamile zifaka isisindo se-molecular, i-degree of hydrolysis, i-inicity, i-viscosity, okuqukethwe okuseleyo, okuseleyo okuseleyo, njll. Lezi zinkomba kufanele zicaciswe ngokuya ngamanzi angcolile oyelaphayo.

1. Isisindo se-molecular / i-viscosity

I-PolyAcrylamide inezinsimbi ezahlukahlukene zamangqamuzana, ukusuka eziphansi kuya phezulu kakhulu. Isisindo samangqamuzana sithinta ukusebenza kwama-polymers kuzicelo ezihlukile. Isisindo esiphakeme se-molecular polylacrylamide sivame ukusebenza ngempumelelo kwinqubo ye-floccation ngoba amaketanga awo we-polymer mude futhi angaxhumana nezinhlayiya eziningi ndawonye.

I-viscosity yesixazululo sePam iphakeme kakhulu. Lapho i-Ionization iqinile, incithakale isisindo samangqamuzana ePoliyacrylamide, kukhula okukhulu kwekhambi layo. Lokhu kungenxa yokuthi i-macromolecular chain ye-polyracrylamide yinde futhi ibe mncane, futhi ukumelana nokunyakaza kwikhambi kukhulu kakhulu.

2. Degree of hydrolysis kanye ne-inicicity

I-Ionicity of Pam inethonya elikhulu emphumeleni walo wokusebenzisa, kepha inani layo elifanele lincike othandweni kanye nohlobo lwezinto eziphikiwe, futhi kunamanani ahlukile aphezulu ezimweni ezihlukile. Lapho amandla e-Ionic e-Prepated Material aphezulu (udaba olungaphezulu), i-Ionicity ye-PAM esetshenzisiwe kufanele ibe ngaphezulu, uma kungenjalo kufanele kube phansi. Ngokuvamile, izinga le-anion libizwa ngokuthi ama-degree of hydrolysis, futhi izinga le-ion livame ukubizwa ngokuthi izinga le-cation.

Ungayikhetha kanjani i-polyyacrylamideKuya ngama-colloids ama-colloids futhi amiswe ama-solids emanzini. Ngemuva kokuqonda izinkomba ezingenhla, kanjani ukukhetha i-pam efanelekile?

1. Qonda umthombo wokukhucululwa kwendle

Okokuqala, kufanele siqonde umthombo, imvelo, ukwakheka, okuqukethwe okuqinile, njll.

Ngokuvamile, i-cationic polyyacrylamide isetshenziselwa ukwelapha i-organic sludge, futhi i-anionic polyyamide isetshenziselwa ukwelapha i-inorganic sludge. Lapho i-PH iphakeme, i-cationic polyyacrylamide akufanele isetshenziswe, futhi lapho, i-anionic polyyacrylamide akufanele isetshenziswe. I-acidity enamandla yenza kungalungele ukusebenzisa i-anionic polyyamide. Lapho okuqukethwe okuqinile kwe-sludge kuphezulu, inani lama-polyyamide asetshenzisiwe likhulu.

2. Ukukhetha kwe-Ionicity

Okokubhodleni okudinga ukukhishwa emanzini ekwelashweni kwendle, ungakhetha ama-flocculant nge-ionicicity ehlukene ngokusebenzisa izivivinyo ezincane ukukhetha i-polycrylamide efanelekile, ongafinyelela umthelela omuhle kakhulu we-flocrylaling futhi unciphise umthamo, izindleko zokonga.

3. Ukukhetha isisindo molecular

Ngokuvamile, kuphakama isisindo samangqamuzana emikhiqizo ye-polycalide, kukhuphuka kakhulu, kepha kusetshenziswa, kukhuphuka isisindo se-molecular somkhiqizo, umphumela ongcono wokusebenzisa. Ngokusetshenziswa okuthile, isisindo esifanele sama-polycacrylamide kufanele sinqunywe ngokuya ngomkhakha wohlelo lwangempela, ikhwalithi yamanzi kanye nemishini yokwelashwa.

Uma uthenga futhi usebenzisa uPam okokuqala, kunconywa ukuhlinzeka ngesimo esithile sendle kumenzi we-flocculant, futhi sizoncoma uhlobo lomkhiqizo olufanele kakhulu kuwe. Namasampula eposi wokuhlola. Uma unesipiliyoni esiningi ekwelashweni kwakho kwendle, ungasitshela izidingo zakho ezithile, izinkambu zohlelo lokusebenza, nezinqubo, noma zisinike ngqo amasampula e-pam owusebenzisayo njengamanje, futhi sizokufanisa ne-polysacrylamide efanelekile.
