Ibara rya polyurethane ni ugutwikira hasi bikoreshwa cyane mu nganda, ubucuruzi n'amashingiro. Igizwe na Polyurethane Resin, umukozi ushinzwe umukozi, pigment n'abahuze, n'ibindi, kandi afite kurwanya icyubahiro, imiti irwanya ikirere. Ibiranga nyamukuru bya polyurethane igorofa irimo:
1. Kwambara kwambara Ikomeye: Ibara rya Polyurethane rifite imbaraga nziza zo guhangana kandi zikwiranye ahantu hirengeye, nkamahugurwa, ububiko no guhaha.
2. Kurwanya imiti: Ifite imbaraga nziza kubintu bitandukanye bya shimi (nka peteroli, aside, nibindi), kandi bikwiranye nibidukikije nkibimera na laboratoire.
3. Ibyiza byiza: Irangi rya Polyurethane rifite urwego runaka rwa elastike, rushobora kurwanya neza ubumuga buto bwubutaka no kugabanya ibicamo.
4. Inda: Amabara atandukanye arashobora gutegurwa ukurikije ibikenewe. Ubuso buroroshye kandi bworoshye bwo gusukura, kuzamura ibihe byerekana ibidukikije.
Intambwe yo kubaka
Inzira yubwubatsi ya Polyurethane Igorofa iragoye kandi ikeneye gukurikiza intambwe zikurikira:
1. Gutunga cyane
Sukura: Menya neza ko hasi ari umukungugu, amavuta nubundi ntamwanda. Koresha imbunda yo mu rwego rwo hejuru cyangwa isuku yinganda ya vacuum yo gukora isuku.
Gusana: Gusana ibice hamwe nibinogo kuruhande kugirango urebe neza neza.
Gusya: koresha urusyo kugirango usubize hasi kugirango wongere amahano yo gupfuka.
2. Gusaba Primer
Hitamo Primer: Hitamo primer ikwiye ukurikije uko ibintu bimeze, mubisanzwe Polyurethane Pristers Prisr ikoreshwa.
Gukaraba: Koresha uruziga cyangwa gukubita imbunda kugirango ushyireho primer rwose kugirango wemeze ubwishingizi. Nyuma ya Prirs yumye, reba ahantu hose yabuze cyangwa ntanganiye.
3. Kubaka ikote hagati
Gutegura guhimba hagati: Tegura ikarito Hagati ukurikije amabwiriza yibicuruzwa, mubisanzwe wongeyeho umukozi.
Gukaraba: Koresha scraper cyangwa umwirondoro kugirango ushyire hamwe ikoti ryita hejuru kugirango wongere ubunini no kwambara ihohoterwa hasi. Nyuma yikoti hagati yo hagati yuzuye, umucanga.
4. Gusaba Topcoat
Tegura Topcoat: Hitamo ibara nkuko bikenewe kandi utegure Topcoat.
Gusaba: Koresha uruziga cyangwa gukubita imbunda kugirango ushyire hejuru ya Topcoat neza kugirango umenye neza. Nyuma ya Topcout yumye, reba uburinganire bwo kwipfuka.
5. Kubungabunga
Igihe cyo kubungabunga: Nyuma yo gushushanya irangiye, irakenewe neza. Mubisanzwe bifata iminsi irenga 7 kugirango hare neza ko amabara hasi yakize rwose.
Irinde igitutu gikomeye: Mugihe cyo gukiza, irinde gushyira ibintu biremereye kuruhande kugirango wirinde kuba wizeye ubuziranenge.
Ubushyuhe nubushuhe: Witondere ubushyuhe bwibidukikije nubushuhe mugihe cyo kubaka. Ingaruka yo kubaka mubisanzwe mubihe bya 15-30 ℃.
Kurinda umutekano: uturindantoki turinda, masike na Goggles bigomba kwambarwa mugihe cyo kubaka kugirango umutekano wemeze umutekano.
