Itandukaniro nyamukuru riri hagati y’amazi ashingiye ku ruhu rwa PU n’uruhu rusanzwe rwa PU ni kurengera ibidukikije, ibintu bifatika, uburyo bwo kubyaza umusaruro hamwe n’uburyo bukoreshwa.
Kurengera ibidukikije: Uruhu rwa PU rushingiye ku mazi rukoresha amazi nk'uburyo bwo gukwirakwiza mu buryo bwo kubyaza umusaruro, bityo rero ntabwo ari uburozi, ntibwaka, kandi ntibuhumanya ibidukikije. Ifite ibiranga kuzigama ingufu, umutekano no kurengera ibidukikije. Ibinyuranye, uruhu rusanzwe rwa PU rushobora kubyara imyanda yangiza kandi yangiza imyanda n’amazi mabi mugihe cyo kuyakoresha no kuyakoresha, bigira ingaruka runaka kubidukikije no kubuzima bwabantu.
Imiterere yumubiri: Uruhu rushingiye ku mazi rwa PU rufite imiterere myiza yumubiri, harimo imbaraga zishishwa ryinshi, kwihanganira cyane, kwihanganira kwambara cyane, nibindi. Nubwo uruhu rusanzwe rwa PU narwo rufite ibintu bimwe na bimwe bifatika, ntibishobora kuba byiza nkuruhu rwa PU rushingiye kumazi mubijyanye no kurengera ibidukikije no kuramba.
Igikorwa cyo kubyaza umusaruro: Uruhu rwa PU rushingiye ku mazi rukozwe mu buryo bwihariye bushingiye ku mazi hamwe n’ibikoresho byangiza ibidukikije, kandi bifite ibyiza byo kwihanganira kwambara neza no kurwanya ibishishwa, hamwe no kurwanya hydrolysis ndende. Izi nyungu zikomoka kubutaka bushingiye kumazi hamwe nubufasha bufasha, bikubye kabiri imyambarire yabwo ndetse no kurwanya ibishushanyo, bikubye inshuro zirenga 10 ugereranije n’ibicuruzwa bisanzwe by’uruhu rusanzwe. Igikorwa cyo gukora uruhu rusanzwe rwa PU ntirushobora kubamo kurengera ibidukikije hamwe nikoranabuhanga ritezimbere imikorere.
Ahantu hashyirwa mu bikorwa: Uruhu rwa PU rushingiye ku mazi rukoreshwa cyane mu bice byinshi nk'inkweto, imyambaro, sofa, n'ibicuruzwa bya siporo bitewe no kurengera ibidukikije ndetse n'imiterere myiza y'umubiri, kandi byujuje ibisabwa bitandukanye kugira ngo urusheho kubungabunga ibidukikije mu ruhu no mu mahanga. Nubwo uruhu rusanzwe rwa PU narwo rukoreshwa cyane mugushushanya imifuka, imyambaro, inkweto, ibinyabiziga nibikoresho byo mu nzu, aho ikoreshwa birashobora gukumirwa mu rwego rwo kurushaho kubungabunga ibidukikije.
Muri make, uruhu rwa PU rushingiye kumazi rufite ibyiza bigaragara kuruhu rusanzwe rwa PU mubijyanye no kurengera ibidukikije, imitungo yumubiri, uburyo bwo kubyaza umusaruro ndetse nuburyo bukoreshwa, kandi ni ibikoresho byujuje neza ibisabwa bigezweho byo kurengera ibidukikije nibisabwa cyane.
