Polyurethane namira: Features uye nokurondedzerwa

Polyurethane guruu iri fuma ane yakawanda dhigirii. Chief pakati pavo vari ayo pakawanda. Rinogona kushandiswa gluing matombo, hukawanika regirazi, simbi, matanda, zvedongo, polyurethane uye polystyrene, uyewo zvimwe zvinhu. Izvi imhaka yakakwirira adhesion pakati murwiyo kune mhando dzose idzi nezvinhu. Sezvo bhainda zvino anoshanda polyurethane, kuti zviri pachena kubva rokuremekedza.

Remubatanidzwa rayo rubatsiro hukawanika kunovimbisa nemishonga kuti mishonga, tembiricha kunyanyisa, siyana kurwisa zvinhu zvakatipoteredza, matunhu tembiricha unyoro. remubatanidzwa kwakadaro kunogona kushanda mune navanopinda tembiricha siyana kubva -60 kusvika +120 Celsius. Uyezve, polyurethane namira inopa simba kubatana, akatsiga kusvikira migumisiro mananara zvakadai achitanga uye pathogenic notumwe. podvspenivaniya pfuma kunoita kuti tive nechokwadi chokuti nzvimbo pakati chokuedza hukawanika vave Akavazadza chose. Kusavapo ari zvokufembedzwa nezvinonhuhwira kunovimbisa kunonyanyisa kuchengeteka munguva oparesheni.

Pane vaviri-chinoumba uye mumwe-chikamu polyurethane namira. Kusarudza wechipiri nyore kushandisa uye usability kukuru. In ayo mamiriro pane isocyanate prepolymers. Nokuda mukuru viscosity zvibereko anopa kwazvo kutanga ezvinhu. kuita isocyanate pamwe mumhepo mwando kunotungamirira makemikari maitiro. Its mugumisiro ndiye paumbwe muchinjikwa samolecular zvisungo, saka kuti kubatana anova simba kwazvo.

Two-chinoumba polyurethane namira rine wayo maumbirwo vaviri yenhengo iyo kana kushandiswa chete vane pasi viscosity. Chete mushure zvokuimba vaiitawo akaita isocyanate remubatanidzwa uye polyol achirapa mumiriri, chinoguma nenzira kushanda mamiriro namira. Sanganisa zvakamisa hurongwa zvakafanira tichinyatsodzidza kuchengeta zvimwe muitiro zvinhu, i.e. zvinodiwa kukura, urefu nguva netembiricha. Kana zvakarurama nzira nzira yacho kwokukurukurirana yenhengo. Maererano zvose ezvinhu kunotungamirira ndechokuti simba zvechadenga kubatana achishandisa polyurethane namira rwakasimudzwa chaizvo.

Guruu kwakavakirwa polyurethane kunogona kubatsira zvikuru kuisa parquet paburiro. For ezvinhu Russian Zvinokurudzirwa kushandisa miviri-chinoumba Formulations dzinenge dzisina zvokufembedzwa kana mvura. nziyo kwakadaro vanokwanisa kukurira zvinhu chero uchishandisa mutoro, saka vanofanira kushandiswa kuisa bhodhi kana nguvo. The polyurethane namira angashandiswa zvinenge zvose mhando nezvigadziko pasina rinoda rokutanga priming. Vakasara hurongwa kubvisa chete zvakakwana. Polyurethane namira chendangariro refu fura simba.
