Te polyurethane (nga paninga, te hiri, te whakapiri)

Ko te makuku i roto i te punaha PU ka tauhohe ki te isocyanate, ahakoa i roto i nga hua polyurethane kotahi-waahanga, e rua-waahanga ranei, e whakaputa ana i te amine me te hauhautanga, kei te noho tonu te amine ki te isocyanate, na reira ko tana kohi ki te tuku i te hau hau i te wa ano, ka puta he mirumiru i runga i te mata o te kiriata peita, ka paheke, ka paheke ranei te mahi o te kiriata peita.

2%~5% o te tatari rāpoi (paura) i roto i te pūnaha he rawaka ki te tango i te toenga makuku i roto i te pūnaha PU, engari te reira te mutunga i runga i te makuku i roto i te pūnaha.

Te paninga anti-corrosive

I roto i te epoxy zinc-taonga tuatahi, he nui te wai ka puta he tauhohenga nui ki te paura konutea, ka whakaputa i te hauwai, te whakanui ake i te pehanga i roto i te oko, te whakapoto i te ora o te mahi o te tuatahi, ka hua mai i te piri, te mau atete me te pakeke. o te kiriata paninga.Ko te tatari rapoi (paura) hei whakamaroke mo te tango wai, ko te whakaurunga tinana katoa, ka whakakore i te wai me te kore he tauhohe ki te tïpako.Na he haumaru, he watea hoki te tatari molecular mo te punaha whakakikorua anti-corrosive.

Te paninga paura whakarewa

He rite nga tauhohenga ka puta i roto i nga paninga paura whakarewa, penei i nga paninga paura konumohe.
