Diphanele tsa sandwich ke thepa ea kaho ea sejoale-joale e sebelisoang haholo lits'ebetsong tsa kaho le tsa meaho ka lebaka la ho thibela mocheso hantle, thepa e bobebe le matla a mechini. Thepa ea mantlha e sebelisoang ho tlatsa liphanele tsena e bapala karolo ea bohlokoa ho khetholleng litšobotsi tsa tsona tsa ts'ebetso. E 'ngoe ea thepa e sebelisoang haholo bakeng sa ho tlatsa liphanele tsa sandwich ke foam ea polyurethane.
Foam ea Polyurethane: Thepa ea Bohlokoa e Ratoang
Foam ea polyurethane ke khetho e tsebahalang bakeng sa ho tlatsa liphanele tsa sandwich ka lebaka la thepa ea eona e phahameng ea ho thibela mocheso, tlhaho e bobebe, le botšepehi ba sebopeho. Ke mofuta oa polymer o hlahisoang ke ho kopanya diisocyanate le polyols, e leng se fellang ka foam e ka fetoloang ho latela litlhoko tse itseng tsa bongata le matla. Ho feto-fetoha hona ho etsa hore foam ea polyurethane e be e loketseng mefuta e mengata ea lits'ebetso, ho tloha mehahong ea bolulo ho ea lits'ebetsong tsa indasteri.
Matlotlo a ho Sireletsa Thermal
Lebaka le leng la mantlha leo ka lona foam ea polyurethane e ratoang bakeng sa ho tlatsa liphanele tsa sandwich ke litšobotsi tsa eona tse ntle tsa ho thibela mocheso. Foam ea polyurethane e na le conductivity e tlase ea mocheso, e leng se bolelang hore e fokotsa phetiso ea mocheso lipakeng tsa tikoloho ea kahare le kantle. Thepa ena e bohlokoa bakeng sa ho boloka ts'ebetso e ntle ea matla mehahong, kaha e thusa ho boloka libaka tsa kahare li futhumetse mariha le ho pholile lehlabula, ka hona e fokotsa tlhoko ea ho futhumatsa le ho pholisa ho feteletseng.
Matla a Bobebe le a Sebopeho
Ho sa tsotellehe tlhaho ea eona e bobebe, foam ea polyurethane e fana ka matla a bohlokoa a sebopeho ho liphanele tsa sandwich. Sebopeho sa sele sa foam se tlatsetsa bokgoning ba eona bo phahameng ba ho jara moroalo le ho hanyetsa khatello. Motsoako ona oa bobebe le matla o molemo haholo kahong, moo ho fokotsa boima ba thepa ea kaho ho ka lebisang ho bolokeng litšenyehelo mabapi le lipalangoang le ho kenya, ntle le ho beha seriti sa sebopeho sa moaho kotsing.
Khanyetso ea Mollo le ho Tšoarella
Lifomo tsa polyurethane tsa sejoale-joale tse sebelisoang liphanele tsa sandwich hangata li entsoe ho ntlafatsa ho hanyetsa mollo, li fihlela litekanyetso tse thata tsa polokeho. Ho feta moo, foam ea polyurethane e tšoarella ebile e hanela mongobo, lik'hemik'hale le ho senyeha ha baeloji, e leng se netefatsang hore liphanele tsa sandwich li phela nako e telele. Ho tšoarella hona ho etsa hore liphanele tsa sandwich tse tletseng polyurethane e be khetho e tšepahalang bakeng sa maemo a fapaneng a leholimo le maemo a tikoloho.

Ho tenyetseha ha foam ea polyurethane e le thepa ea ho tlatsa ho atolosa ts'ebeliso ea eona ho feta meaho e tloaelehileng ea meaho. Liphanele tsa sandwich tse nang le li-core tsa polyurethane li sebelisoa libakeng tsa polokelo tse batang, likoloing tse sehatsetsing, esita le kahong ea likamore tse hloekileng le libakeng tse laoloang moo ho hlokahalang taolo e thata ea mocheso le mongobo.
Qetello
Qetellong, foam ea polyurethane e hlahella e le thepa e ratoang bakeng sa ho tlatsa liphanele tsa sandwich ka lebaka la ho thibela mocheso ka mokhoa o ikhethang, sebopeho se bobebe empa se le matla, ho hanyetsa mollo le ho tšoarella. Ho ikamahanya ha eona le bongata le matla a fapaneng ho e etsa hore e lokele mefuta e mengata ea lits'ebetso, ho tloha mehahong ea bolulo le ea khoebo ho ea lits'ebetsong tse ikhethileng tsa indasteri. Jwalo ka mofani oa li-catalyst tsa polyurethane, re ananela karolo ea bohlokoa eo foam ea polyurethane ea boleng bo holimo e e bapalang ho ntlafatseng ts'ebetso le katleho ea liphanele tsa sandwich, 'me re ikemiselitse ho tšehetsa boqapi bo tsoelang pele le nts'etsopele ea thepa ena ea bohlokoa ea kaho.
