Polyurethane (zomatira, zosindikizira, zomatira)

Chinyezi mu dongosolo PU amachitira ndi isocyanate, ziribe kanthu mu chigawo chimodzi kapena awiri chigawo polyurethane mankhwala, amene amapanga amine ndi mpweya woipa, amine kupitiriza kuchita ndi isocyanate, kuti mowa wake kumasula mpweya woipa wa carbon dioxide nthawi yomweyo. kupanga thovu pamwamba pa filimu ya utoto, zomwe zimabweretsa kuwonongeka kapena ngakhale kulephera kwa filimu ya utoto.

2% ~ 5% ya sieve ya molekyulu (ufa) m'dongosolo ndiyokwanira kuchotsa chinyezi chotsalira mu dongosolo la PU, koma pamapeto pake zimatengera chinyezi m'dongosolo.

Anti-corrosive zokutira

Mu epoxy zinc olemera primer, kuchuluka kwa madzi kumatulutsa kuchitapo kanthu kwakukulu ndi nthaka ufa, kupanga haidrojeni, kuonjezera kupanikizika mu mbiya, kufupikitsa moyo wautumiki wa primer, zomwe zimabweretsa kulimba, kukana kuvala ndi kuuma. wa filimu yophimba.Sieve ya molekyulu (ufa) ngati desiccant yotengera madzi, yomwe imakhala yowoneka bwino, imachotsa madzi ndipo popanda kuchitapo kanthu ndi gawo lapansi.Chifukwa chake sieve yama cell ndi yotetezeka komanso yabwino kwa anti-corrosive coating system.

Metal ufa wokutira

Zofananazo zitha kuchitika mu zokutira zaufa zachitsulo, monga zokutira zaufa za aluminiyamu.
