Batho ba bangata ba nang le mathata a ho phekola metsi, ba lokisa bubble ea pele, bubble holim'a metsi, bubble, bubble, bubble, peroxide e potolohang pheko ea metsi ea foam ea bactericide ea cic le e seng oxidizing, joalo-joalo, ka hona, kalafo ea metsi ke e 'ngoe ea ts'ebeliso e tloaelehileng. ea ho tlosa bubble agent, pampiri ena e hlahisa molao-motheo oa defoaming agent, lihlopha, khetho le tšebeliso.
Mokhoa oa ho tlosa foam
1. Mekhoa ea 'mele
Nahana ka mokhoa oa fisiks ho tlosa mekhoa ea foam haholo-holo e kenyelletsa baffle kapa mesh, mochini o susumetsang, electrostatic, sehatsetsi, ho futhumatsa, ho hlahisa mouoane, mahlaseli, lebelo le phahameng la centrifugal, khatello ea khatello, vibrate e phahameng, ho tsoa hang-hang le ultrasonic acoustic liquid (taolo) , joalo-joalo, ea mekhoa ena ka tekanyo e fapaneng e khothalletsoang ka tekanyo le lera la mokelikeli lipheletsong tse peli tsa filimi ea bubble ea khase ea drainage, The stabilizing factor of the bubbles are less than decaying factors, le palo ea bubble butle-butle fokotseha.Empa bothata bo tloaelehileng ba mekhoa ena ke hore ts'ebeliso ea litšitiso tsa maemo a tikoloho, sekhahla sa defoaming ha se phahame, molemo o teng ts'ireletsong ea tikoloho, sekhahla se phahameng sa ho sebelisoa hape.
2. Mekhoa ea lik'hemik'hale
Mekhoa ea ho tlosa li-foam ho tsoa ponong ea lik'hemik'hale e kenyelletsa karabelo ea lik'hemik'hale le ho eketsa defoamer.
Chemical reaction method e bua ka karabelo ea lik'hemik'hale lipakeng tsa li-reagents tse ling le ntho e phophomang ho hlahisa lintho tse sa qhibiliheng, ka hona, e fokotsa bongata ba ntho e kenang ka har'a filimi ea mokelikeli le ho khothalletsa ho phatloha ha lekoeba.Leha ho le joalo, mokhoa ona o na le mefokolo joalo ka sebopeho se sa tsitsang sa moemeli oa foaming le lintho tse kotsi tse sa tsitsang lisebelisoa tsa sistimi.Hona joale mokhoa o sebelisoang ka ho fetisisa oa ho tlosa lekoba mefuteng eohle ea bophelo ke mokhoa oa ho eketsa ntho e senyang lekoba.Monyetla o moholo oa mokhoa ona ke hore o sebetsa hantle ebile o bonolo ho o sebelisa, empa senotlolo ke ho fumana moemeli ea nepahetseng le ea sebetsang hantle oa ho tlosa lefome.
Molao-motheo oa defoamer
Defoaming agent, eo hape e tsejoang e le defoaming agent, e na le melao-motheo e latelang:
1. Khatello ea sebaka sa sebaka sa foam e fokotsehile, e fella ka ho phatloha ha foam
Mochine o qala ha joala bo phahameng kapa oli ea meroho e sebelisoa ho foam, eo, ha e qhibiliha ka foam, e fokotsa haholo tsitsipano ea holim'a metsi moo.Hobane lintho tsena hangata ha li qhibilihe ka metsing, phokotso ea tsitsipano e holim'a metsi e lekanyelitsoe sebakeng sa sebaka sa foam, athe tsitsipano e holim'a foam e sa fetohe.Karolo ea tsitsipano e fokotsehileng holim'a metsi e huloa ka matla ka mahlakoreng 'ohle, e atolosoa,' me qetellong e phunye.
2, senya elasticity ea filimi le ho lebisa ho phatloha ha bubble
Ha sesebelisoa sa defoaming se eketsoa tsamaisong ea foam, se tla hasana ho sebopeho sa mokelikeli oa khase, se etsa hore ho be thata ho motho ea nang le foam e tsitsitseng ho khutlisa elasticity ea filimi.
3, ho khothaletsa drainage ea filimi ea metsi
Defoaming moemeli ka khothalletsa metsi filimi drainage, fella ka bubble phatlohile, tekanyo ea foam drainage ka bonahatsa botsitso ba bubble, phaella ka ho re lintho tse bonahalang tse ho potlakisa foam drainage, ka boela phetha karolo ea defoaming.
4, ho eketsa likaroloana tse tiileng tsa hydrophobic ho ka lebisa ho phatloha ha bubble
Likaroloana tse tiileng tsa hydrophobic tse holim'a li-bubble li tla hohela pheletso ea hydrophobic ea li-surfactants, e le hore likaroloana tsa hydrophobic li hlahise hydrophilicity mme li kenelle mothating oa metsi, e le hore li ka bapala karolo ea ho senya.
5, solubilizing foam surfactant e ka lebisa ho phatloha ha bubble
Lintho tse ling tse tlase tsa limolek'hule tse tsoakaneng hantle le mokelikeli li ka qhibilihisa "bubbling surfactant" le ho fokotsa khatello ea eona e sebetsang.Lintho tse tlase tsa limolek'hule tse nang le phello ena, joalo ka octanol, ethanol, propanol le lino tse ling tse tahang, li ke ke tsa fokotsa feela mahloriso a surfactant holim'a lera, empa hape li qhibiliha ka har'a lera la adsorption, li fokotsa ho tiea lipakeng tsa limolek'hule tse surfactant, ka hona tsa fokolisa botsitso ba foam.
6. Electrolyte e qhaqha lera le habeli la surfactant
Bakeng sa surfactant ka thuso ea bubble habeli lera lera tshebedisano, botsitso ba foaming mokelikeli, phaella ka ho re tloaelehileng electrolyte ka putlama surfactant habeli lera motlakase ho phetha karolo ea defoaming.
