Uruhu rwa PU ni iki? Nigute dushobora gutandukanya uruhu rwa PU nimpu nyazo?

‌Uruhu rwa PU ni ibikoresho byakozwe n'abantu. Ni uruhu rwubukorikori rusanzwe rufite isura kandi rukumva uruhu nyarwo, ariko ruhendutse, ntiruramba, kandi rushobora kuba rufite imiti. ‌
Uruhu rwa PU ntabwo ari uruhu nyarwo. Uruhu rwa PU ni ubwoko bwuruhu rwubukorikori. Ikozwe mubikoresho bya fibre fibre, mugihe uruhu nyarwo rukozwe kandi rutunganywa kuruhu rwinyamaswa. Uruhu nyarwo ruvugwa ku isoko muri rusange ni urwego rwa mbere rwuruhu naho urwego rwa kabiri rwuruhu.
Uruhu rwa PU, izina ryuzuye ni uruhu rwa polyurethane, ni ibikoresho bya sintetike bikozwe mugukoresha polimeri yubukorikori hejuru yububiko bwinyamaswa. Iyi myenda isanzwe irimo polyurethane. Uruhu rwa PU rufite imbaraga zo kwambara neza, guhumeka, kurwanya gusaza no guhinduka. Ingaruka yo kugaragara isa cyane nimpu nyayo, kandi niyo iruta uruhu rusanzwe mubintu bimwe bifatika. Ariko, ugereranije nimpu nyazo, uruhu rwa PU rufite itandukaniro muburyo burambye, kubungabunga no kurengera ibidukikije.
Nigute uruhu rwa PU rukozwe? Izina ryuzuye ryuruhu rwa PU ni uruhu rwa polyurethane. Ikozwe mugukoresha polyurethane resin kumyenda cyangwa imyenda idoda, hanyuma ikanyuzwa mubikorwa nko gushyushya no gushushanya kugirango igire amabara atandukanye, imiterere nubunini. Uruhu rwa PU rushobora kwigana isura no kumva uruhu rutandukanye nyarwo, nk'inka, uruhu rwintama, uruhu rwingurube, nibindi.

Ni izihe nyungu z'uruhu rwa PU? Ubwa mbere, uruhu rwa PU rworoshye kandi ntiruremerera ibirenge. Icya kabiri, uruhu rwa PU rwihanganira kwambara kandi ntabwo byoroshye gushushanya cyangwa kwangirika. Icya gatatu, uruhu rwa PU rworoshye kurwoza, gusa ruhanagure nigitambaro gitose. Hanyuma, uruhu rwa PU rwangiza ibidukikije kandi ntiruzangiza inyamaswa cyangwa imyanda.

None, ni izihe ngaruka mbi z'uruhu rwa PU? Ubwa mbere, uruhu rwa PU ntiruhumeka, rutuma ibirenge ibyuya cyangwa binuka byoroshye. Icya kabiri, uruhu rwa PU ntirurwanya ubushyuhe bwinshi kandi rukunda guhinduka cyangwa gusaza. Icya gatatu, uruhu rwa PU ntabwo rworoshye kandi rworoshye bihagije, kandi ntirufite ubuhanga kandi rukwiranye nimpu nyazo. Hanyuma, uruhu rwa PU ntabwo ruri hejuru kandi rufite ubushyuhe buhagije, kandi ntirufite ububengerane nuburyo bwuruhu rwukuri.
‌Uburyo bwo gutandukanya uruhu rwa PU nimpu nyazo zirimo:

‌Ibikoresho n'ibigize: Uruhu nyarwo ruva mu ruhu rw'inyamaswa, kandi nyuma yo gutwika hamwe nibindi bikorwa, rufite imiterere yihariye kandi ikoraho. Uruhu rwa PU ni uruhu rwubukorikori, hamwe na polyurethane resin nkibintu byingenzi, bikozwe nubushakashatsi bwimiti, hamwe no kurwanya neza kwambara, kurwanya crease no kurwanya gusaza.
Kugaragara no gukoraho: Uruhu nyarwo rutanga uburyo busanzwe kandi nyabwo hamwe nuburyo budasanzwe. Nubwo uruhu rwa PU rushobora kwigana imiterere no gukoraho uruhu nyarwo, iracyagaragara muri rusange. Uruhu nyarwo rufite imirongo isobanutse neza, kandi buri gice kiratandukanye. Imirongo yimpu ya PU irarenze kandi yonyine. Uruhu nyarwo rwumva rworoshye kandi rworoshye, rworoshye kandi rworoshye. Uruhu rwa PU rwumva rufite intege nke kandi rukomeye.

Kuramba: Uruhu nyarwo rusanzwe ruramba, rufite ubukana bwinshi kandi bworoshye, kandi rushobora kurwanya ingaruka ziterwa no guterana amagambo. Nubwo uruhu rwa PU rufite imbaraga zo kurwanya kwambara, rushobora gusaza, guturika nibindi bibazo nyuma yo gukoresha igihe kirekire.
Kubungabunga no kwitaho: Uruhu nyarwo rusaba kubungabungwa no kubitaho buri gihe, kandi ibikoresho byihariye byo kwita kumpu bikoreshwa mugusukura, kubitsa no kwirinda amazi. Uruhu rwa PU rworoshye kubyitaho, gusa uhanagure nigitambaro gitose.
Kurinda ibidukikije ‌: Uruhu nyarwo ruva mu ruhu rw’inyamaswa, kandi usanga hari imyanda mike hamwe n’umwanda mubikorwa byayo. Nkuruhu rwubukorikori, uruhu rwa PU rushobora gutera umwanda mubidukikije mugikorwa cyarwo.
Ibyerekeye umunuko: Uruhu nyarwo rufite impumuro isanzwe yimpu, kandi ruba impumuro nziza uko ibihe bigenda bisimburana. Uruhu rwa PU ruzaba rufite impumuro nziza ya plastike. Uruhu nyarwo ruzagabanuka kandi impumuro yumusatsi waka iyo uhuye numuriro. Uruhu rwa PU ruzashonga kandi runuka nka plastiki yaka iyo ihuye numuriro.
Gukoreshwa mubihe bitandukanye

Kwambara buri munsi: Kubicuruzwa byuruhu byo kwambara burimunsi, nkinkweto namashashi, abaguzi barashobora guhitamo bakurikije ibyo bakeneye na bije. Niba ukurikirana ihumure no guhumeka, uruhu nyarwo ni amahitamo meza; niba witaye cyane kubiciro no kugaragara bitandukanye, uruhu rwa PU narwo ni amahitamo meza.

Ibihe bidasanzwe: Mubihe bimwe bidasanzwe, nk'inama zubucuruzi, gusangira ibyokurya bisanzwe, nibindi, ibicuruzwa byimpu byukuri byerekana ubwiza nubushake bwiyubashye. Mubihe bimwe bisanzwe, nka siporo yo hanze, ingendo, nibindi, ibicuruzwa byuruhu rwa PU bitoneshwa kubera ubworoherane nigihe kirekire.
Muncamake, uruhu rwa PU nimpu nyazo buriwese afite ibimuranga hamwe nibintu byakoreshwa. Abaguzi bagomba guhitamo bakurikije ibyo bakeneye na bije mugihe baguze.
