Inkqubo ye-scouring yinkqubo enzima ye-physicochemical, kubandakanywa nemisebenzi yokungena, ukufaka i-emulsifying, ukusabalalisa, ukuhlamba kunye nokutshiza, njl. njl.i-arhente yokucocakwinkqubo yokukhuhla ikakhulu ibandakanya le miba ilandelayo.
1.Ukumanzisa kunye nokungena.
Ukungena kubalulekile kwinkqubo yokukhuhla.Okokuqala, kwinkqubo yeumqhaphuukukhula, i-galacturonic acid yepectin idibanisa kancinane neCa2+kunye noMg2+kumanzi aphantsi komhlaba ukwenza iityuwa zepectin ezinganyibilikiyo emanzini kwaye kunzima ukufunxa.I-Pectin isasazwa eludongeni oluphambili lwe-cellulose surface kwaye ivimbela i-hygroscopicity yodonga lwangaphakathi lwesibini, olubalelwa kwi-98% ye-cellulose.Izinto ze-waxy kwifayibha yomqhaphu kunye nokungcola okunamafutha kwi-arhente yokulinganisa okushiyekileyo kwenza kube nzima kwi-agent ekhuhlayo ukuba ingene kwi-fibrous.umsontoIzikhewu ezibandakanya ii-capillaries ezidibeneyo zobukhulu obahlukeneyo.Okwesibini, inkqubo yokucoca iqhutyelwa kwisisombululo sesoda ye-caustic kwindawo ethile.Ngenxa yokuba uxinzelelo lomphezulu lwesisombululo se-caustic soda luphezulu kakhulu, kunzima ukuba i-agent ekhuhlayo ingene.Ukuze wenze inkqubo yokucoca iphumelele, kuyimfuneko ukukhupha iifiber kunye nokuphucula ipropati ye-interface phakathi kwesisombululo kunye nefayibha, efuna ukongeza i-surfactant efanelekileyo enokunciphisa ukuxinwa komphezulu wesisombululo kunye noxinzelelo phakathi kwesisombululo kunye nefayibha.Ukuze i-fiber iqhagamshelane ne-agent ehlanjululweyo ngakumbi kwaye ingcono, ikhawuleza ukumanzisa kunye nokungena.
Ngokwethiyori esisiseko yokumanzisa kunye nokungena, nge-adsorption kwi-interface, i-surfactants inokunciphisa kakhulu i-γLG kunye ne-γLS, ukwenza ukumanzisa kube lula.Kwangaxeshanye, inokonyusa ulwelo ikholamu static uxinzelelo lwe capillary ukunyuka, nto leyo enenzuzo scouring agent ukuba ingene kwindawo yangaphakathi imicu.Umgangatho we-ejenti yokukhuhla ixhomekeke kakhulu kumandla ayo okunciphisa ukuxinezeleka komhlaba kunye nesantya sokungena.
2.Ukuhlamba i-detergent.
Umsebenzi wokuhlamba i-detergent kwinkqubo yokucoca unzima kakhulu.Okokuqala, kufuneka yenze buthathaka amandla okuncamathelisa phakathi kwe-waxy saponified substance kunye neoyile kunye namalaphu kwaye icuthe ujongano ngokuthe ngcembe.Kwaye emva koko isusa igrisi kwilaphu ngokwenza ngoomatshini kwaye ifake i-emulsion yamanzi e-oyile ukunqanda ukuba ingangcoliswa kwakhona.Ii-non-ionic surfactants ngokubanzi zigqwesile zokumisela imixube.Nangona i-anionic surfactants iya kwenza i-electrode ephindwe kabini kwi-waxy / interface yamanzi ukukhusela i-oil particles ukuba idibanise kunye, oko kunenzuzo ukwenza inkqubo ye-emulsion ezinzile.Okwesibini, kufuneka isasaze ukubola kwe-alkali ukuthintela ukungcoliseka kwakhona, okuya kusebenzisa umsebenzi wokusasaza we-surfactants, kunye nomsebenzi wezinye i-inorganic okanye i-organic chelating dispersing agents.
Uhlobo olulodwa okanye ulwakhiwo lwe-surfactant lunzima ukufezekisa ngempumelelo ezi ziphumo zingentla ngexesha elinye, ngoko ke kuyimfuneko ukudibanisa ngaphezu kweentlobo ezimbini ezahlukeneyo kunye nezakhiwo ezahlukeneyo ze-surfactants.Iyakwazi ukulungelelanisa ngokufanelekileyo iintlobo zazo, izakhiwo kunye nomgaqo-siseko ukuze zinike i-Hydrophile Lipophilic Balance (HLB) efanelekileyo ukuhlangabezana neemfuno ze-emulsifying ukungcola kwegrisi, kwaye inomthamo owaneleyo we-micellar kunye ne-CMC ephantsi ngokwaneleyo kunye noxinzelelo lwangaphandle (γCMC).Iya kwenza inkqubo ye-arhente yokucoca igcine ukusebenza kakuhle kokumanzisa kunye ne-emulsification egqwesileyo, ukusasazeka kunye neempawu zokucoca.
