Hlahisa:
Marangrang a pharaletseng a litsamaiso tsa likhoerekhoere tse ka tlas'a lefatše a phetha karolo ea bohlokoa ho bolokeng bophelo bo botle ba sechaba le bohloeki. Har'a mefuta e fapaneng ea liphaephe tse sebelisoang litsamaisong tsena, liphaephe tse nang le polyurethane li hlahile e le boqapi bo hlahelletseng. Blog ena e ikemiselitse ho hlakisa bohlokoa, melemo le ts'ebeliso ea liphaephe tse nang le polyurethane tšimong ealikhoerekhoeremolas.
Ithute ka phaephe e nang le polyurethane:
Phaephe e nang le polyurethane, eo hape e bitsoang phaephe e nang le PU, ke phaephe ea tšepe e nang le polyurethane ka mokhoa o ikhethileng oa tlhahiso. Lesela le na le khanyetso e ntle khahlanong le ho tsofala, ho bola le lik'hemik'hale, e leng se etsang hore e be e loketseng ho tsamaisa likhoerekhoere le lintho tse ling tse senyang.
Melemo ea liphaephe tse koahetsoeng ka polyurethane:
1. Ho tšoarella ho matlafalitsoeng: Lesela la polyurethane le thibela ho senyeha le ho taboha ha liphaephe, le eketsa bophelo ba liphaephe tsa hau haholo. E hanela ho senyeha ho bakoang ke marotholi a lebelo le phahameng, lintho tse tiileng le lintho tse ling tse senyang tse atisang ho fumanoa metsing a litšila.
2. Ho hanyetsa mafome: Polyurethane e na le khanyetso e ntle ea lik'hemik'hale le khanyetso ea mafome. Tšebeliso ea eona e le lesela la kahare e netefatsa tšireletso ea nako e telele khahlanong le lintho tse senyang tse atisang ho ba teng ka har'a likhoerekhoere, joalo ka hydrogen sulfide.
3. Phallo e boreleli: Bokaholimo bo boreleli haholo ba lesela la polyurethane bo fokotsa khohlano 'me bo khothalletsa phallo e tsoelang pele, e sa khaotseng. Sena se fokotsa tšebeliso ea matla, ho theoha ha khatello le monyetla oa ho bokellana ha lithōle, ho netefatsa phetiso e sebetsang hantle ea metsi a litšila.
Lisebelisoa tsa liphaephe tse koahetsoeng ka polyurethane:
1. Litsamaiso tsa likhoerekhoere tsa masepala: Liphaephe tse nang le polyurethane li sebelisoa haholo litsamaisong tsa likhoerekhoere tsa masepala ho tsamaisa likhoerekhoere ka katleho le ho fokotsa tlhokomelo. Ho hanyetsa mafome le bokhoni ba tsona ba ho mamella lebelo le phahameng la mokelikeli li etsa hore li be ntle bakeng sa ho tsamaisa metsi a litšila libakeng tsa bolulo, tsa khoebo le tsa indasteri.
2. Phekolo ea litšila tsa indasteri: Metsi a litšila a indasteri hangata a na le lintho tse khorofo le tse senyang, tse bakang mathata meralong ea motheo ea liphaephe tse teng. Liphaephe tse nang le polyurethane li fana ka tharollo e tšepahalang ka ho sireletsa khahlanong le khoholeho e bakoang ke likaroloana tse tiileng le lik'hemik'hale tse senyang.
3. Mesebetsi ea Merafo: Liphaephe tse nang le polyurethane li ntse li sebelisoa haholoanyane lits'ebetsong tsa merafo ka lebaka la ho hanyetsa ho tsofala ha tsona hantle. Li sebetsana ka katleho le ho tsamaisoa ha lerōle, li-tailings le lihlahisoa tse ling tsa merafo ha ka nako e ts'oanang li fokotsa nako ea ho sebetsa ka lebaka la tlhokomelo.
4. Indasteri ea oli le khase: Lefapheng la oli le khase, liphaephe tse nang le polyurethane li sebelisoa mekhahlelong e fapaneng e kang ho cheka, ho merafo le ho hloekisa. Li ipakile li sebetsa hantle ho sebetsaneng le lintho tse senyang, lik'hemik'hale tse senyang, esita le maro a mocheso o phahameng.
Ha re phethela:
Phaephe e nang le polyurethane e fetotse lefatše laphaephe e tjheseditsweng, e fanang ka melemo e kang ho tšoarella, ho hanyetsa mafome le thepa e ntlafetseng ea phallo. Tšebeliso ea tsona lits'ebetsong tsa likhoerekhoere tsa masepala, ho lahla litšila tsa indasteri, mesebetsing ea merafo, le indastering ea oli le khase e pakile ho tenyetseha ha tsona le ho tšepahala ha tsona. Ha linaha li ntse li loanela ho boloka meralo ea motheo ea taolo ea litšila e sebetsang hantle, kopanyo ea liphaephe tse koahetsoeng ka polyurethane e netefatsa botsitso ba nako e telele le katleho ea litšenyehelo.
