Litaba - Valve ea Thipa ea Polyurethane e nang le Mela e Felletseng e Hanelang ho Hlōla

Valve ea heke ea thipa ea polyurethane ke eng?

Valve ea heke ea thipa ea polyurethanee bolela valve ea heke ea thipa e nang le tiiso ea setulo sa valve ea polyurethane.Polyurethane (PU)E na le litšobotsi tsa ho hanyetsa oli, ho hanyetsa ho tsofala, ho hanyetsa mocheso o tlase, ho hanyetsa botsofali, ho thatafala ho hoholo, ho tenyetseha ho hoholo le ts'ebetso e ntle ea ho thibela chefo. Hangata e sebelisoa bakeng sa likaroloana tse thata haholo le liphaephe tse mahareng tse nang le khase le mokelikeli. E na le ts'ebetso e ntle ea ho koala le ho hanyetsa ho tsofala ho matla haholo.

Polyurethane e tsejoa e le "rabara e sa tsofaleng". Khanyetso ea eona ea oli ha e tlase ho feta ea rabara ea nitrile 'me e lekana le rabara ea polysulfide. E loketse haholo liphaephe tse fapaneng tse mahareng tse hlokang ho koaloa ho hoholo le khoholeho ea likaroloana tse matla haholo.
