Polymer ke eng?
Li-polymerske metsoako e entsoeng ka limolek'hule tse kopantsoeng hammoho ka liketane. Hangata liketane tsena li telele 'me li ka phetoa ho eketsa boholo ba sebopeho sa molek'hule. Limolek'hule tsa motho ka mong ka ketane li bitsoa monomers, 'me sebopeho sa ketane se ka sebelisoa kapa sa fetoloa ho fihlela thepa le thepa e itseng.
Ho thehoa ha letsopa le nang le merero e mengata ke ts'ebeliso ea meaho e fetotsoeng ea limolek'hule tsa polymer. Sengoliloeng sena, leha ho le joalo, re tla tsepamisa maikutlo ho li-polymers indastering,ka ho khetheha phekolo ea metsi a polymer.
Li-polymers li ka sebelisoa joang ho hloekisa metsi?
Li-polymers li thusa haholo ho hloekisa metsi a litšila. Ka kutloisiso ea motheo, mosebetsi oa liketane tsena tsa limolek'hule ke ho arola karolo e tiileng ea metsi a litšila ho tsoa ho mokelikeli oa 'ona. Hang ha likarolo tse peli tsa metsi a litšila li arohane, ho bonolo ho phethela ts'ebetso ka ho arola ho tiileng le ho hloekisa metsi, ho siea metsi a hloekileng e le hore a ka lahloa ka mokhoa o sireletsehileng kapa bakeng sa lisebelisoa tse ling tsa indasteri.
Ka kutloisiso ena, polymer ke flocculant - ntho e sebetsanang le lintho tse tiileng tse leketlileng ka metsing ho etsa lihlopha tse bitsoang floc. Sena se na le thuso haholo lits'ebetsong tsa ho hloekisa metsi a litšila, ka hona, li-polymers hangata li sebelisoa li le mong ho etsa hore ho be le flocculation, e ka tlosang lintho tse tiileng habonolo. Leha ho le joalo, e le hore u fumane liphello tse molemo ka ho fetisisa ts'ebetsong ena, li-polymer flocculants li atisa ho sebelisoa ka li-coagulants.
Li-coagulants li nka mokhoa oa flocculation ho li isa boemong bo latelang, li bokella lihlopha hammoho ho etsa lesela le teteaneng la seretse se ka tlosoang kapa sa phekoloa ho ea pele. Polymer flocculation e ka etsahala pele ho tlatsetso ea li-coagulants kapa e ka sebelisoa ho potlakisa ts'ebetso ea electrocoagulation. Hobane electrocoagulation e na le melemo le mathata ka bobeli, tšebeliso ea li-polymer flocculants ho ntlafatsa ts'ebetso ke tlhahiso e khahlang bakeng sa batsamaisi ba setsi.
Mefuta e fapaneng ea li-polymers tsa ho hloekisa metsi
Phekolo ea metsi a polymer e ka sebetsa ka mekhoa e fapaneng ho latela mofuta oa monoma o sebelisitsoeng ho etsa ketane ea polymer. Li-polymers ka kakaretso li oela likarolong tse peli tse pharaletseng. Ke cationic le anionic, e buang ka litefiso tse amanang le liketane tsa limolek'hule.
Li-polymer tsa anionic ho phekola metsi
Li-polymer tsa anionic li qosoa hampe. Sena se etsa hore li tšoanelehe ka ho khetheha bakeng sa ho phalla ha lintho tse thata tse sa tsitsang, joalo ka letsopa, silt kapa mefuta e meng ea mobu, ho tsoa litharollong tsa litšila. Metsi a litšila a tsoang mererong ea merafo kapa indastering e boima e kanna ea ba le lintho tse ngata tse tiileng, kahoo li-polymer tsa anionic li ka ba molemo haholo lits'ebetsong tse joalo.
Li-polymers tsa cationic ka ho hloekisa metsi
Mabapi le tefiso e lekanyelitsoeng, polymer ea cationic ha e le hantle e fapane le polymer ea anionic hobane e na le tefiso e ntle. Tefiso e ntle ea li-polymers tsa cationic li etsa hore e be tse loketseng bakeng sa ho tlosa lintho tse tiileng tse tsoang mefuteng ea metsi a litšila kapa metsoako. Hobane liphaephe tsa likhoerekhoere tsa sechaba li na le lintho tse ngata tse phelang, li-polymers tsa cationic li atisa ho sebelisoa libakeng tsa tsamaiso ea likhoerekhoere tsa masepala, le hoja lisebelisoa tsa temo le lijo le tsona li sebelisa li-polymers tsena.
Li-polymers tse tloaelehileng tsa cationic li kenyelletsa:
Polydimethyl diallyl ammonium chloride, polyamine, polyacrylic acid / sodium polyacrylate, cationic polyacrylamide, joalo-joalo.
