Irangi ryo hasi rya polyurethane ni irangi ryo hasi rikora neza cyane rikoreshwa cyane mu nyubako z'inganda, iz'ubucuruzi n'iz'abaturage. Rigizwe na polyurethane resin, icyuma gikingira, amarangi n'ibindi, kandi rifite ubushobozi bwo kudashira neza, rirwanya imiti ndetse rikanarwanya ikirere. Ibintu by'ingenzi biranga irangi ryo hasi rya polyurethane birimo:
1. Ingufu zikomeye zo kwangirika: Irangi ryo hasi rya polyurethane rishobora kwangirika neza kandi rikwiriye ahantu hahurira abantu benshi, nko mu maduka, mu bubiko no mu maduka.
2. Ubudahangarwa ku binyabutabire: Ifite ubudahangarwa bwiza ku bintu bitandukanye bya shimi (nk'amavuta, aside, alkali, nibindi), kandi ikwiriye ibidukikije nko mu bimera bya shimi na laboratwari.
3. Gukomera neza: Irangi ryo hasi rya polyurethane rifite ubushobozi bwo gukomera, rishobora kurwanya neza imiterere mito y'ubutaka no kugabanya icyuho.
4. Ubwiza: Amabara atandukanye ashobora gutegurwa hakurikijwe ibyo ukeneye. Ubuso buraryoshye kandi bworoshye gusukura, binoza ubwiza bw'ibidukikije.
Intambwe zo kubaka
Uburyo bwo kubaka irangi rya polyurethane hasi buragoye cyane kandi bugomba gukurikiza intambwe zikurikira:
1. Gutunganya ubuso bw'ibanze
ISUKU: Menya neza ko hasi nta mukungugu, amavuta n'indi myanda irimo. Koresha imbunda y'amazi ifite umuvuduko mwinshi cyangwa imashini isukura amazi mu nganda kugira ngo isukurwe.
Gusana: Gusana imyenge n'ibinogo biri hasi kugira ngo habeho ubuso bworoshye bw'ishingiro.
Gusya: Koresha icyuma gisya kugira ngo utunganye hasi kugira ngo wongere uburyo igitambaro gifatana.
2. Gukoresha primer
Hitamo primer: Hitamo primer ikwiye ukurikije uko ibintu bimeze, ubusanzwe primer ya polyurethane ikoreshwa.
Koza: Koresha agakoresho kabugenewe cyangwa imbunda itera imiti kugira ngo ushyireho primer neza kugira ngo urebe ko ipfundikiye. Iyo primer imaze kuma, reba aho ipfundikiye cyangwa aho ipfundikiye.
3. Imiterere y'amakoti yo hagati
Gutegura irangi ryo hagati: Tegura irangi ryo hagati ukurikije amabwiriza y'umuti, ubusanzwe wongeramo umuti uvura.
Koza: Koresha agakoresho ko gusya cyangwa gukaraba kugira ngo ushyireho neza agakoresho ko hagati kugira ngo wongere ubunini n'ubudasaza bw'ubutaka. Nyuma y'uko agakoresho ko hagati kamaze kuma, kasukure.
4. Gukoresha ikoti ryo hejuru
Tegura ikoti ryo hejuru: Hitamo ibara uko bikenewe hanyuma utegure ikoti ryo hejuru.
Gukoresha: Koresha imbunda ikoresha icyuma gishyushya cyangwa imbunda itera umwanda kugira ngo ushyireho topcoat neza kugira ngo ubuso bube bwiza. Nyuma yuko topcoat yumye, reba niba ipfundikizo ringana.
5. Kubungabunga
Igihe cyo kubungabunga: Nyuma yo gusiga irangi, hakenewe ko rikorwa neza. Ubusanzwe bifata iminsi irenga 7 kugira ngo irangi ryo hasi ribe ryakize neza.
Irinde igitutu gikomeye: Mu gihe cyo gushonga, irinde gushyira ibintu biremereye hasi kugira ngo wirinde kugira ingaruka ku bwiza bw'igitambaro.
Ubushyuhe n'ubushuhe: Itondere ubushyuhe n'ubushuhe bw'ikirere mu gihe cyo kubaka. Ingaruka zo kubaka akenshi ziba nziza iyo ikirere kiri hagati ya 15-30°C.
Uburinzi bw'umutekano: Udupfukantoki, udupfukamunwa n'amadarubindi bigomba kwambarwa mu gihe cyo kubaka kugira ngo umutekano ube mwiza.
