Polyurethane foam ke polymer e phahameng ea molek'hule.Sehlahisoa se entsoeng ka polyurethane le polyether se kopantsoeng ka bokhabane.Ho fihlela joale, ho na le mefuta e 'meli ea foam e tenyetsehang le foam e thata' marakeng.Har'a tsona, foam e thata ke sebopeho sa lisele tse koetsoeng, athe foam e tenyetsehang ke sebopeho sa lisele tse bulehileng.Mehaho e fapaneng e na le likarolo tse fapaneng tsa ts'ebeliso.
Te sebetsa ka polyurethane foam
Polyurethane foam e ka bapala karolo ea ho thibela.Ebang ke foam e thata kapa foam e tenyetsehang, thepa e ntle ebile e ka thijoa.Ha e le hantle, e ka boela ea e-ba le phello e thibelang molumo, 'me e ka sebelisoa libakeng tse ling ho arola melumo e meng hantle haholo.Ts'ebetso e tlase ea mocheso le ts'ebetso e ntle ea ho kenya mocheso oa mocheso.Ka foam e thata ea foam ea polyurethane, ho na le thepa e nang le mocheso oa mocheso le mesebetsi e sa keneleng metsi, e fokotsang mocheso oa mocheso.Likarolong tse ling, ho hlokahala hore ho be le sekontiri se joalo se tlaase sa mocheso, 'me li-adhesives tse ling ha lia lokela ho sebelisoa.
Thekopofoam ea polyurethane
Ho boloka matla le ho sireletsa tikoloho.Joaloka ho tlatsa, lekhalo le ka tlatsoa ka ho feletseng, 'me ts'ebetso ea sekhomaretsi e ka finyelloa.Ka mor'a ho phekola, e ka khomarela ka thata 'me e na le bophelo bo bolelele ba tšebeletso.
Compression le shockproof.Ha foam ea polyurethane e phekotsoe ka ho feletseng, ho ke ke ha e-ba le ho phunyeha, ho senya le ho senya.E na le mefuta e mengata ea lisebelisoa le mefuta e mengata ea lisebelisoa.E ka sebelisoa ka matla a macha, indasteri ea sesole, phekolo ea meriana, lifofane, likepe, lisebelisoa tsa elektronike, likoloi, lisebelisoa, lisebelisoa tsa motlakase, seporo se phahameng, joalo-joalo, ka conductivity e tlaase, ho hanyetsa mocheso o motle, le ho boloka mocheso.E sebelisoa ho lisebelisoa tsa elektroniki, phepelo ea motlakase le masimong a mang, e khona ho hanela tikoloho ea mocheso o phahameng le ho fana ka ts'ebetso ea ho futhumatsa mocheso.
Ho thibela molumo le ho sireletsa.Ha foam ea polyurethane e phekoloa ka ho feletseng, e ka thibela mongobo haholo le ho thibela metsi.Esita le tikolohong e lefifi le e mongobo, ho ke ke ha e-ba le mathata.
