Ho Utloisisa Foam e Tiileng ea Polyurethane
Foam e tiileng ea polyurethane e khetholloa ka sebopeho sa eona sa lisele tse koetsoeng, se fanang ka tšireletso e ntle ea mocheso, matla a mechini le botsitso ba litekanyo. Litšobotsi tsena li etsa hore e be thepa e loketseng bakeng sa ho sireletsa mehaho, li-unit tsa sehatsetsing, le lits'ebetso tse ling moo ho boloka mocheso le botsitso ba sebopeho ho leng bohlokoa. Tlhahiso ea foam e tiileng ea boleng bo holimo e hloka taolo e nepahetseng holim'a lik'hemik'hale tse amehang, e leng moo Catalyst e leng teng.193 e bapala karolo ea bohlokoa.
Karolo ea Catalyst193
Sehokelo193 e hlophisitsoe ka ho khetheha ho nolofatsa ho thehoa ha foam e thata ea polyurethane ka ho potlakisa karabelo lipakeng tsa isocyanate le polyols. Likarabelo tsa mantlha tsa lik'hemik'hale tse amehang ho etseng foam ea polyurethane ke karabelo ea polymerization le karabelo ea ho foka.
1. Karabelo ea Polymerization: Ena ke karabelo pakeng tsa isocyanate le polyol, e lebisang ho thehoeng ha khokahano ea urethane, e leng mokokotlo oa polyurethane polymer.193 e khothalletsa karabelo ena, e netefatsa hore liketane tsa polymer li thehoa kapele le ka mokhoa o tsitsitseng.
2. Karabelo e Fokang: Sena se kenyeletsa karabelo ea li-isocyanate ka metsi ho hlahisa khase ea carbon dioxide, e leng se etsang sebopeho sa sele ea foam.193 e boetse e thusa karabelong ena, e netefatsa hore khase e hlahisoa ka ho lekana, e leng se lebisang boholong le kabong e tsitsitseng ea sele ka har'a foam.
Ho Ntlafatsa Matlotlo a Foam
Bokgoni ba Catalyst193 ho khothaletseng liketso tsena ho fella ka melemo e 'maloa ea bohlokoa bakeng sa foam e thata ea polyurethane:
- Ho Ntlafatsa ho Futhumatsa ha ThermalKa ho netefatsa sebopeho se tšoanang sa sele e koetsoeng,193 e thusa ho etsa foam e nang le thepa e ntle ea ho thibela mocheso, e leng se etsang hore e sebetse hantle haholo lits'ebetsong tsa ho boloka matla.
- Botšepehi ba Sebopeho: Karabelo e potlakileng le e tsitsitseng ea polymerization e khothaletsoang ke193 e fella ka foam e nang le matla a phahameng a mechini le ho tiea, e leng ea bohlokoa bakeng sa lits'ebetso tsa ho jara mojaro.
- Botsitso ba Tekanyo: Sehokelo193 e thusa ho fihlela foam ka ho fokotseha ho fokolang le botsitso bo boholo, e leng sa bohlokoa bakeng sa ho boloka botšepehi ba ho thibela mocheso kahong le sehatsetsing ha nako e ntse e ea.
Ts'ebetso ea Kopo
Ts'ebetsong ea tlhahiso, CatalystHangata 193 e kopanngoa le karolo ea polyol pele e kopanngoa le isocyanate. Ho kopanya hona pele ho nako ho netefatsa hore catalyst e ajoa ka ho lekana ho pholletsa le polyol, e leng se lebisang karabelong e tšoanang ha likarolo li kopanngoa. Motsoako oa karabelo o tšeloa kapa o kenngoa ka har'a hlobo kapa holim'a libaka, moo foam e thehoang le ho fola ka potlako.
Qetello
Sehokelo193 e emela tsoelo-pele e kholo tlhahisong ea foam e tiileng ea polyurethane, e fanang ka taolo e ntlafalitsoeng holim'a liketso tsa bohlokoa tse khethollang thepa ea foam. Ka ho potlakisa liketso tsa polymerization le tsa ho foka,193 e netefatsa tlhahiso ea foam ea boleng bo holimo e nang le ho thibela mocheso ho phahameng, matla a mechini le botsitso ba litekanyo. Ha liindasteri li ntse li tsoela pele ho batla thepa e fanang ka ts'ebeliso e ntle ea matla le ts'epo ea sebopeho, Catalyst193 e hlahella e le karolo ea bohlokoa ho fihlelleng litlhoko tsena, e leng se susumetsang boqapi 'marakeng oa foam ea polyurethane.
