Phenolic resin ke e 'ngoe ea lisebelisoa tsa bohlokoa tse tala liindastering tse kang li-brake pads le abrasives. Metsi a litšila a hlahisoang nakong ea tlhahiso ea phenolic resin ke bothata bo boima ho bahlahisi.
Phenolic resin e hlahisoang ke metsi a litšila a na le likhahla tse ngata tsa phenols, aldehydes, resin le lintho tse ling tsa manyolo, 'me a na le litšobotsi tsa khatello e phahameng ea manyolo, chefo e phahameng le pH e tlase. Ho na le mekhoa e mengata ea ts'ebetso ea ho phekola metsi a litšila a nang le phenol, 'me mekhoa e sebelisoang haholo e kenyelletsa mekhoa ea lik'hemik'hale, mekhoa ea lik'hemik'hale tsa oxidation, mekhoa ea ho ntša metsi, mekhoa ea adsorption, le mekhoa ea ho tlosa khase.
Lilemong tsa morao tjena, ho hlahile mekhoa e mengata e mecha, e kang mokhoa oa catalytic oxidation, mokhoa oa ho arohana ha membrane ea metsi, joalo-joalo, empa mererong ea sebele ea phenolic resin ea ho hloekisa metsi a litšila, haholo-holo e le ho finyella litekanyetso tsa ho qhala, mekhoa ea biochemical e ntse e le mokhoa o tloaelehileng. Mohlala, mokhoa o latelang oa phenolic resin kalafo ea metsi a litšila.
Ntlha ea pele, etsa phekolo ea condensation holim'a metsi a litšila a phenolic resin, ntša le ho khutlisa resin ho eona. Joale, lik'hemik'hale le li-catalyst li kenngoa metsing a litšila a phenolic resin ka mor'a phekolo ea mantlha ea condensation, 'me phekolo ea bobeli ea condensation e etsoa ho tlosa phenol le formaldehyde.
Metsi a litšila a phenolic resin ka mor'a hore phekolo ea bobeli ea condensation e kopane le metsi a litšila a pompo, boleng ba pH bo fetoloa ho 7-8, 'me bo lumelloa ho ema. Ebe u tsoela pele ho eketsa ClO2 ho catalytically oxidize metsi a litšila ho fokotsa litaba tsa formaldehyde le COD. Ebe u eketsa FeSO4, 'me u fetole boleng ba pH ho 8-9 ho tlosa CloO2 e tlisoang ke mohato o fetileng.
Metsi a litšila a phenolic resin a hloekisitsoeng pele a tla fuoa kalafo ea biochemical ea SBR ho tlosa litšila tse ka metsing ka likokoana-hloko.
Metsi a litšila a hlahisoang ke phenolic resin a hloekisoa pele, ebe a tsosolosoa, e le hore metsi a litšila a ka fihla boemong bo tloaelehileng.
