Uruhu rwa pu rudafite solvent ni iki?

Uruhu rwa PU rudafite solvent ni uruhu rw'ubukorano rudahungabanya ibidukikije rugabanya cyangwa rukirinda burundu ikoreshwa ry'ibintu bihumanya ikirere mu ikorwa ryarwo. Uburyo gakondo bwo gukora uruhu rwa PU (polyurethane) bukunze gukoresha ibintu bihumanya ikirere nk'ibintu bigabanya ibidukikije cyangwa inyongeramusaruro, bishobora kugira ingaruka mbi ku bidukikije no ku buzima. Kugira ngo bigabanye iyi ngaruka, uruhu rwa PU rudafite solvent rukoresha uburyo butandukanye bwo gukora, nk'ikoranabuhanga rikoresha amazi cyangwa ubundi buryo burengera ibidukikije, kugira ngo rusimbuze ibintu bihumanya ikirere bisanzwe.

None se uruhu rwa PU rudafite solvent rukorwa rute?
Reka tubanze turebe uburyo uruhu rwa PU rudafite solvent rukorwa:
1. Gutegura igitambaro cyo hasi: Ubwa mbere, ugomba gutegura igitambaro cyo hasi, gishobora kuba ipamba cyangwa ibindi bikoresho by’ubukorikori. Iki gitambaro kizaba ishingiro ry’uruhu rwa PU,
2. Igikoresho cyo gusiga: Shyira urwego rwa primer ku mwenda wo hasi. Ubusanzwe iyi substrate iba ari polyurethane (PU), ifite ubushobozi bwo gufata neza kandi igakomeza kwangirika.
3. Gusiga urwego rwo hejuru: Iyo icyuma cy'imbere cyumye, shyiramo urwego rw'urukundo. Uru rwego kandi rukozwe muri polyurethane, rugena uko uruhu rwa PU ruteye n'uko rumera. Hari ibice bimwe na bimwe by'ubuso bishobora gukenera ubuvuzi bwihariye, nko gushushanya, gucapa cyangwa gukoresha uruhu rwigana, kugira ngo uruhu rwongere imiterere n'ubwiza bwarwo.
4. Kumisha no gusiga: Nyuma yo kurangiza gusiga irangi mu mpeshyi, uruhu rwa PU rwoherezwa mu cyumba cyo kumisha cyangwa binyuze mu bundi buryo bwo gusiga, kugira ngo primer n'urwego rw'ubuso bivurwe neza kandi bihuzwe.
5. Kurangiza no gukata: Nyuma y’uko uruhu rwa PU rutunganyijwe, hagomba gukorwa igikorwa cyo kurangiza, harimo no gukata imiterere n’ingano byifuzwa kugira ngo hakorwe ibikoresho bya nyuma by’uruhu, nk’amasakoshi, inkweto, nibindi. Ingingo y’ingenzi muri iki gikorwa cyose ni ugukoresha irangi rya polyurethane (PU) ridafite solvent. Izi plaque ntizisohora solvent organic cyangwa ngo zirekure solvent nke cyane mu gihe cyo gusiga, bityo bikagabanya umwanda w’ibidukikije n’ingaruka ku buzima bw’abakozi.

Kuki uruhu rwa pu rudafite solvent rurushaho gukundwa cyane muri iki gihe?
Ese twese dufite ikibazo, iyo tugiye mu isoko kugura sofa cyangwa ibikoresho byo mu nzu, tukabona sofa nziza kandi igezweho y'uruhu rwera cyangwa ibikoresho by'uruhu, twifuza kugura, ariko nanone tugahangayikishwa nuko sofa y'uruhu rwera idakira umwanda, idakira gushwaragurika, idakosoka neza, akenshi tuzayireka kubera iyi mpamvu, none ntugahangayike, nta ruhu rwa PU rufite solvo, dushobora kugufasha muri iki kibazo. Uruhu rwa PU rudafite Solvo rufite uburinzi bw'ibidukikije, rufite imikorere myiza kandi rufite imikorere myinshi, ariko kandi rufite imiterere yo kudashwara, kudashwara no koroshya gusukura, bityo dushobora guhitamo uruhu rwa PU rudafite solvo rukozwe muri sofa yera, ntitugomba guhangayikishwa nuko sofa yera idahumanye, ntitugomba guhangayikishwa nuko abana babi bashushanya kuri sofa bakoresheje ikaramu.
Uruhu rwa PU rudafite solvent ruhura n’ibyo abaguzi n’abakora ibikoresho bigezweho bakeneye ku bwiza bw’ibicuruzwa no kwita ku bidukikije, ibyo bigatuma rurushaho kuba rwiza ku bidukikije no ku bidukikije, bityo rukaba rukunzwe cyane ku isoko.
