Kuki wahitamo polyurethane ku bikoresho byo mu nganda kandi ni izihe nyungu zayo?

Polyurethane (PU), izina ryuzuye rya polyurethane, ni polymer compound, yakozwe mu 1937 na Otto Bayer n'abandi. Polyurethane ifite ibyiciro bibiri by'ingenzi: polyester na polyether. Zishobora gukorwamo plastiki za polyurethane (cyane cyane ifuro), fibre za polyurethane (zizwi nka spandex mu Bushinwa), polyurethane rubber na elastomer. Polyurethane ni ibikoresho bya polymer byiza gukoreshwa nk'igipfukisho cy'uruziga mu gukora ibikoresho by'inganda bicukura.

Ibyiza by'ingenzi bya polyurethane casters ni ibi bikurikira:

Ubwa mbere, imikorere y'urwego rushobora guhindurwa

Ibipimo by'imikorere bifatika n'ibijyanye n'imikorere bishobora guhindurwa binyuze mu guhitamo ibikoresho fatizo n'amafimu, mu buryo butandukanye bwo guhindura ibintu, kugira ngo bihuze n'ibyo umukoresha akeneye mu mikorere y'ibicuruzwa.

Icya kabiri, kurwanya cyane kwangirika kw'ibinure
Iyo hari amazi, amavuta n'ibindi bikoresho bitose, polyurethane casters irwanya kwangirika kw'ibikoresho bisanzwe bya kabutike inshuro nyinshi kugeza ku nshuro nyinshi. Ibikoresho by'icyuma nk'icyuma n'ibindi bikomeye, ariko si ngombwa ko birwanya kwangirika!

Icya gatatu, uburyo bwo gutunganya, uburyo bwo gukoresha ibintu mu buryo bwagutse
Elastome za polyurethane zishobora gutegurwa hakoreshejwe plastike, kuvanga no gukurura (MPU); zishobora kandi gukorwamo plastike y'amazi, gusuka no gushushanya cyangwa gutera, gufunga no gushushanya centrifugal (CPU); zishobora kandi gukorwamo ibikoresho bya granular na plastike isanzwe hakoreshejwe inshinge, gusohora, gushushanya, gukurura no gukoresha izindi nzira (CPU). Ibice byabumbwe cyangwa bikozwe mu ishinge, biri mu rwego runaka rw'ubukana, bishobora kandi gucibwa, gusya, gucukura no gutunganya ubundi buryo bwa mashini.

Icya kane, kurwanya amavuta, kurwanya ozone, kurwanya gusaza, kurwanya imirasire, kurwanya ubushyuhe buke, gutuma amajwi akwirakwira neza, imbaraga zikomeye zo gufata neza, guhuza neza mu binyabuzima no guhuza amaraso. Izi nyungu ni zo mpamvu nyazo zituma elastomer za polyurethane zikoreshwa cyane mu bya gisirikare, mu by’indege, mu by’amajwi, mu binyabuzima n’ahandi.
