Ts'ebetso ea scouring ke ts'ebetso e rarahaneng ea physicochemical, ho kenyelletsa le mesebetsi ea ho kenella, ho etsa emulsifying, ho qhalakanya, ho hlatsoa le ho chelating, joalo-joalo.moemeli oa ho khoahlapisats'ebetsong ea scouring haholo-holo kenyeletsa lintlha tse latelang.
1.Ho koloba le ho phunyeletsa.
Ho phunyeletsa ho bohlokoa ts'ebetsong ea ho hloekisa.Ntlha ea pele, ts'ebetsong eak'hothonekholo, galacturonic acid ea pectin butle-butle e kopana le Ca2+le Mg2+metsing a ka tlas'a lefatše ho etsa matsoai a pectin a sa qhibiliheng ka metsing 'me ho leng thata ho a buduloa.Pectin e ajoa leboteng la mantlha la selulose 'me e thibela hygroscopicity ea lerako le ka hare la bobeli, le etsang karolo ea 98% ea selulose.Lintho tse nang le boka tse ka har'a fiber ea k'hothone le litšila tse mafura tse ka har'a sekala se setseng li etsa hore ho be thata hore sesebelisoa sa scouring se kenelle ka har'a fibrous.khoelelikheo tse nang le li-capillaries tse hokahantsoeng tsa boholo bo fapaneng.Taba ea bobeli, ts'ebetso ea scouring e etsoa ka tharollo ea soda ea caustic sebakeng se itseng.Hobane tsitsipano e ka holim'a metsi ea caustic soda solution e phahame haholo, ho thata hore sehloekisi se kenelle.E le ho etsa hore ts'ebetso ea scouring e atlehe, hoa hlokahala ho phunya likhoele le ho ntlafatsa thepa ea sehokelo pakeng tsa tharollo le fiber, e hlokang ho eketsa surfactant e loketseng e ka fokotsang tsitsipano ea tharollo le tsitsipano pakeng tsa tharollo le fiber.E le hore fiber e khone ho kopana le moemeli oa ho hloekisa ka botlalo le ho feta, ho potlakisa ho koloba le ho phunyeletsa.
Ho ea ka khopolo ea motheo ea ho kolobisa le ho phunyeletsa, ka adsorption holim'a sebopeho, li-surfactants li ka fokotsa haholo γLG le γLS, ho etsa hore ho be bonolo ho kolobisa.Ka nako e ts'oanang, e ka eketsa khatello e tsitsitseng ea metsi a capillary rising, e leng molemo bakeng sa ho phunyeletsa ho phunyeletsa karolong e ka hare ea likhoele.Boleng ba sesebelisoa sa ho hloekisa bo itšetlehile haholo ka bokhoni ba sona ba ho fokotsa tsitsipano ea holim'a metsi le sekhahla sa ho phunyeletsa.
2.Detergent ea ho hlatsoa.
Mosebetsi oa ho hlatsoa li-detergent nakong ea ho hloekisa o rarahane haholo.Taba ea pele, e tlameha ho fokolisa matla a sekhomaretsi lipakeng tsa waxy saponified substance le oli e mafura le masela le ho honyela sebopeho butle-butle.E ntan'o ntša mafura leselang ka ketso ea mochini ebe e kenya emulsion ea metsi a oli ho thibela ho silafatsoa hape.Li-surfactants tse seng tsa ionic hangata ke li-emulsifiers tse ntle haholo.Le hoja li-surfactants tsa anionic li tla etsa lera la li-electrode tse peli holim'a sebopeho sa boka / metsi ho thibela likaroloana tsa oli hore li se ke tsa kopana, seo se molemo ho theha tsamaiso e tsitsitseng ea emulsion.Taba ea bobeli, e tlameha ho qhalakanya ho bola ha alkaline ho thibela ts'oaetso hape, e tla sebelisa ts'ebetso ea ho qhalakanya ea li-surfactants, le ts'ebetso ea li-inorganic kapa organic chelating dispersing agents.
Mofuta o le mong kapa sebopeho sa surfactant ho thata ho finyella ka katleho liphello tse ka holimo ka nako e le 'ngoe, kahoo hoa hlokahala ho kopanya mefuta e fetang e' meli e fapaneng le mehaho e fapaneng ea li-surfactants.E ka fetola hantle mefuta ea bona, meaho le molao oa motheo ho fana ka eona e loketseng Hydrophile Lipophilic Balance (HLB) ho fihlela litlhoko tsa emulsifying litšila tsa mafura, 'me e na le molumo o lekaneng oa micellar le CMC e tlase e lekaneng le tsitsipano ea holim'a metsi (γCMC).E tla etsa hore sistimi ea scouring e boloke ts'ebetso e ntle haholo ea ho koloba le emulsification e ntle haholo, disperity le thepa ea ho hloekisa.
