IntshayeleloOfI-USeYePolyacrylamide
Sele siyiqondile imisebenzi kunye nemiphumo yeearhente zonyango lwamanzi ngokweenkcukacha. Kukho ulwahlulo oluninzi olwahlukeneyo ngokwemisebenzi kunye neentlobo zazo. I-Polyacrylamide yenye yee-polymers ezithe ngqo, kwaye uthotho lwayo lweemolekyuli lunenani elithile lee-radicals. Ingafunxa amasuntswana aqinileyo axhonywe emanzini, ii-bridge ions okanye amasuntswana ahlanganisiweyo abe yi-flocs enkulu ngokuthomalalisa itshaja, ikhawulezise ukutsalwa kwe-sedimentation yamasuntswana axhonyiweyo, ikhawulezise ukucaciswa kwesisombululo, kwaye iphucule isiphumo sokucoca. Ukusetyenziswa kwayo ngokweenkcukacha kuya kwaziswa apha ngezantsi kuwe.
1. Ukusetyenziswa ekususeni amanzi odaka
Xa isetyenziselwa ukucocwa kwenkunkuma, i-cationic polyacrylamide inokukhethwa ngokwe-sludge, enokuyicocwa ngempumelelo inkunkuma ngaphambi kokuba inkunkuma ingene kwi-filter press. Xa icocwa, ivelisa ii-flocs ezinkulu, ayinamatheli kwilaphu lesihluzo, kwaye ayisasazeki ngexesha lokucocwa kwesihluzo. Ikeyiki yodaka ityebile kwaye ukusebenza kakuhle kokuphelelwa ngamanzi kuphezulu.
2. Ukusetyenziswa ekunyangweni kwamanzi amdaka endalo
Xa isetyenziswa ekunyangweni kwamanzi amdaka asekhaya kunye namanzi amdaka endalo, afana namanzi amdaka okutya notywala, amanzi amdaka avela kwizityalo zokunyanga amdaka asezidolophini, amanzi amdaka ebhiya, amanzi amdaka asefektri ye-MSG, amanzi amdaka eswekile, amanzi amdaka okutya, njl.njl., Isiphumo se-cationic polyacrylamide singcono kuneetyuwa ze-anionic, ezingezizo ze-ionic kunye ne-inorganic amaxesha amaninzi okanye amashumi amaxesha aphezulu, kuba olu hlobo lwamanzi amdaka ngokubanzi lune-negative charge.
3. Ukucocwa kwamanzi angavuthwanga emilanjeni nasemachibini
I-Polyacrylamide ingasetyenziselwa ukunyanga amanzi empompini ngamanzi omlambo njengomthombo wamanzi. Ngenxa yokuba iphantsi kakhulu, inefuthe elihle kwaye ixabisa kancinci, ingakumbi xa isetyenziswa kunye nee-flocculants ezingaphiliyo, ngoko ke iya kusetyenziswa kwizityalo zamanzi njenge-flocculant evela kuMlambo iYangtze, uMlambo iYellow kunye nezinye izitya.
Oku kungasentla kukusetyenziswa okuneenkcukacha kwe-polyacrylamide. Njengearhente yokucoca amanzi, inamandla ngakumbi ekucoceni amdaka. Nangona kunjalo, ukongeza kwiindlela zayo ezibalulekileyo zokusetyenziswa kwezi nkalo zintathu zingasentla, ingasetyenziswa njengearhente yokuqinisa kunye nezinye izongezo ekwenzeni iphepha ukwandisa izinga lokugcina izizalisi kunye neepigment, kunye nokwandisa amandla ephepha; njengezongezo ze-oyile, ezifana nodongwe oluchasene nokudumba. Yiarhente yokuqina kwe-oyile ye-asidi; ingadlala indima enkulu kwiarhente yokulinganisa ilaphu, ukusebenza kokulinganisa okuzinzileyo, ubungakanani obuncinci, izinga eliphantsi lokuphuka kwelaphu, kunye nomphezulu welaphu ogudileyo.
