Kusiyana kwa madzi kusamutsa madzi polyirethane payipi ndi kusinthitsa mafuta a polyurethane

Mipesa yosanja yolumikizira polyileblehane imagawika mitundu ingapo malinga ndi kugwiritsa ntchito zosiyana. Pakati pawo, kunyamula nkhuni za polyirethane Hosses ndi mitengo ya pourerethane yonyamula mafuta ndi magulu awiri wamba. Lero ndidzakumbutsa magulu awiriwa. Kusiyana pakati pa hoses.
Choyamba, hoses ya polyirethane ili ndi zofunikira zosiyanasiyana pamiyala pomwe amagwiritsidwa ntchito kunyamula madzi ndi mafuta. Ma Hosse ogwiritsa ntchito mayendedwe amadzi amafunikira kwambiri hydrophobicity wa TPU kuphimba kuwonongeka kwa nthawi yayitali. Hydrolysis, pomwe panyumba ya polyurethane yomwe imagwiritsidwa ntchito poyendetsa mafuta imafunikira kuti pakhale ndi madzi abwino kwambiri, ndipo payipiyo iyenera kukhala ndi magetsi osokoneza bongo, kuti chinthu chomwe chabisike chimatha kukwaniritsa . Nthawi zambiri, mabizinesi am'madzi a polyelirethane hoses amathanso kugwiritsidwa ntchito ngati hoses yamadzi, koma hoses yamadzi singagwiritsidwe ntchito popereka mafuta. Tinthu tating'onoting'ono tomwe timagwiritsidwa ntchito m'madzi a poldurethane nthawi zambiri zimakhala mtundu wa polyester, pomwe tinthu ta tpu zomwe zimagwiritsidwa ntchito pochotsa mafuta polyithethane nthawi zambiri. Chifukwa mitengo yamitundu yosiyanasiyana imasiyana kwambiri, motero kusamutsa mafuta polyirethane pamtengo wa hosset nthawi zambiri kumakhala kokulirapo kutanthauzira kofananako.
Chifukwa chake, pamene makasitomala amasankha hourethane hoses, ayenera kukhala momveka bwino za cholinga cha hoses, kenako kusankha hose yolingana malinga ndi kugwiritsa ntchito hoses. Kuyembekezera moyo kumachepetsedwa kwambiri, kapena ndalama zambiri zidzagwiritsidwa ntchito.
