Iipolyurethanes zisetyenziswa ngokubanzi iipolymers ezenziwe ngokuphendula i-polyols kunye ne-disocyanates phambi kweekhemikhali ezifana ne-catalysts kunye ne-additives.Zisetyenziselwa ukwenza iimveliso ezahlukeneyo phantse kuwo onke amashishini, afana ne-elektroniki, izithuthi, izihlangu, ulwakhiwo, ukupakishwa, njl., ukuba zibunjwe zibe ziimo ezingaqhelekanga kwaye ziphucule abathengi kunye neemveliso zemizi-mveliso.

Ipolyurethane isetyenziswa njengogwebu oluqinileyo kwiindonga kunye nokugquma uphahla, ugwebu olubhetyebhetye kwifanitshala, nanjengezinto zokuncamathelisa, izinto zokugquma, kunye nezitywini zangaphakathi zeemoto.Zonke ezi zinto zinokubonelela ngenzuzo121 BPSkwimakethi yepolyurethane ngexesha loqikelelo lweminyaka ye-2022-2032.

Ukusetyenziswa okuphambili kwe-polyurethane kwii-elastomers, amagwebu, kunye neengubo zokwaleka ezibonelela ngokugqwesa ukuxhathisa ukonakala.Amagwebu e-polyurethane eqinile asetyenziswa ngokubanzi njengezinto zokugquma ngenxa yokudityaniswa kweendleko-zokusebenza kunye nepropathi yokuhambisa ubushushu obuphantsi.Umgangatho olungileyo wobushushu obuphantsi, ukuguquguquka kolwakhiwo lwemolekyuli ebanzi, ixabiso eliphantsi, kunye nokuxhathisa okuphezulu kwe-abrasion zonke zixhasa ukukhula kwemarike.

Nangona kunjalo, amandla emozulu embi, amandla amancinci obushushu, ukutsha, njl. njl., kunokwenzeka ukuba kuthintele ukukhula kwemfuno ye-polyurethane kwiminyaka ezayo.

Isibhengezo:Eminye imixholo/imifanekiso kweli nqaku ivela kwi-Intanethi, kwaye umthombo uqatshelwe.Zisetyenziselwa kuphela ukubonisa izibakala okanye izimvo ezichazwe kweli nqaku.Zezonxibelelwano kunye nokufunda kuphela, kwaye azikho ezinye iinjongo zorhwebo.Ukuba kukho naluphi na ulwaphulo, nceda uqhagamshelane nathi ukuze ucime ngokukhawuleza.
