Polyurethane yoroshye yubushyuhe bwo hejuru hamwe nigitambara cyo kuzimya umuriro Igishusho

Ibisobanuro bigufi:

Imyenda ya PU ni polyurethane, ikozwe cyane cyane muri fibre fibre fibre igizwe, ifite ibintu bisa nimpu nyazo, gride yimyenda ihendutse, ikoreshwa ryinshi.Bitewe nibintu rusange byoroheje byimyenda ya pu, birashobora kuba byiza cyane kwirinda kwangirika kwamazi, kandi ingaruka zayo zo gufata amazi nibyiza cyane.Nyuma yo gukuramo amazi, ntihazabaho kubyimba cyangwa guhinduka.Igihe kimwe, biroroshye cyane kubyitaho.Nkuruhu, impumuro iroroshye kandi igiciro kirahendutse.

Ibyiza by'imyenda ya PU

Imyenda ya PU ikozwe cyane cyane muri fibre fibre fibre, ariko kandi ifite ibintu bisa, icyarimwe uburemere bworoshye, gukomera gukomeye, guhumeka, kutirinda amazi, ntibyoroshye kwaguka no kurengera ibidukikije, ibintu byiza byumubiri, kurwanya impinduramatwara, byiza ubwitonzi, imbaraga zingana cyane, hamwe no guhumeka ikirere.PU ni iyakabiri yuruhu rwinyuma rwinyuma rwinka, hanyuma igashyirwaho igipande cya PU resin hejuru, imyenda ya pu nayo yitwa firime yinka, ariko igiciro cyayo gihendutse, nigipimo kinini cyo kuyikoresha, ariko hamwe nimpinduka yimikorere yacyo nayo ikorwa mubyiciro bitandukanye byubwoko butandukanye, nkinka, kubera inzira idasanzwe, ubuziranenge buhamye, ubwoko bushya nibindi biranga.

Uburyo bwo guhitamo imyenda ya PU

Reba niba inkombe igororotse, niba hari burrs, ibice, ibyobo, nibindi.;Reba niba irangi rya spray risa neza, ntagituba, ububiko, nibindi.;Koresha ibice bike hamwe, reba niba ikidodo, kigenda neza, nta cyuho kinini kandi gito n'uburebure butandukanye;Amazi agomba kuba hagati ya 8 na 13%.

Uburyo bwo gufata neza imyenda ya PU

Koresha igice cyumye cyumye mugihe cyoza;Nibyiza gushashara rimwe mu gihembwe;Gerageza kwirinda guhura n'amazi menshi;Irinde guhanagura aside na alkaline y'amazi, kugirango utangiza ubuso;Irinde kwikubita hasi.
