Tlhaloso ea mantlha ea thepa ea Pu
Pu e emela Polyurethane, lisebelisoa tsa polymer tse sebelisoang haholo indastering e fapaneng. Polyurethane e hlahisoa ke karabelo ea lik'hemik'hale pakeng tsa isocyatate le polyol, 'me e na le thepa ea lik'hemik'hale e leng' mele le ea lik'hemik'hale. Hobane PO a ka ba le thepa ea eona e fetotsoeng ka ho fetola sebopeho sa eona, e sebelisoa likopo tse fapaneng tsa likopo, ho tloha Aparella ho ea lisebelisoa tsa kaho.
Classifice le thepa ea Pu
Polyurethane e ka khetholloa liforomo tsa mefuta e fapaneng, ho kenyelletsa makhasi a thata, foams, li-elatomers, bolaoli le likhakanyo le likhau Litšiea tse thata li sebelisoa hangata bakeng sa likonopo tsa likhoho, ha li ntse li sebelisoa lifofane tse sebelisoang haholo ka thepa ea thepa le materase. Ka lehlakoreng le leng, li-elatomers tse pontšang elashe ka tsela e kang ea li-elaches 'me li sebelisetsoa seo se le seng, lithaere le joalo. Ka lebaka la phetoho ea eona e ntle, ho hanyetsa oli ea absion, ho hanyetsa oli ea absion le ho hanyetsa oli le botsofali.
Ts'ebeliso ea Pu ho indasteri e fapaneng
Polyurethane e na le lits'ebetso tse fapaneng tsa lits'ebetso libakeng tse fapaneng. Ka mohlala, indastering ea mankana, P e sebelisoa hangata ho hlahiseng letlalo la maiketsetso, e nang le sebopeho se ts'oanang le letlalo empa se bonolo ho se hlokomela. Indastering ea kaho, foam e sebelisoa e le thepa ea boleng bo holimo, e ratoang haholo bakeng sa boitšoaro bo bongata bo bobe le ho hanyetsa. Makhole a koloi, lisebelisoa tsa Puri li sebelisetsoa ho iketsetsa litulo le likarolo tse kahare tsa trim ha li fana ka matšeliso a matle le ho tšoarella.
