PU Uruhu?

Uruhu rwa PU rwitwa Uruhu rwa Polyurethane, ni uruhu rwa synthique rukozwe mubikoresho bya Polyurethane. PU Uruhu ni uruhu rusanzwe, rukoreshwa cyane mubicuruzwa bitandukanye byunganda, nk'imyenda, inkweto, ibikoresho by'imbere n'ibikoresho, gupakira n'izindi nganda.

Kubwibyo, uruhu rufata umwanya wingenzi muruhu rwimpu.

Duhereye ku musaruro no kurinda ibidukikije, uruhu rwa PU rugabanijwe cyane mu bwoko bubiri bw'uruhu rwa PU hamwe n'uruhu gakondo rwa PU.

Ni irihe tandukaniro riri hagati yubwoko bubiri bw'uruhu?

Reka tubanze turebe itandukaniro mubikorwa byabo.

Gakondo ya PU Uruhu:

1. Intambwe yambere mu gukora uruhu rwa PU ni ugukora Polyurethane, na Polypon) na PolyOl) na polyet, polyet hamwe nibikoresho fatizo bikozwe muri Polurethane reaction.

2. Gufunga substrate, Polyurethane Rein yahitanye substrate, nkubuso bwuruhu, substrate irashobora guhitamo imyambaro itandukanye, nka papa, umwenda wa polyester, nibindi bikoresho bya synthete.

3. Gutunganya no kuvura, subst substrate yatunganijwe kandi ikavurwa, nko kwinjirira, gusohora, gusiga irangi nibindi bikorwa, kugirango habeho imiterere isabwa, ibara nibisabwa. Izi ntambwe zitunganya zirashobora gutuma PU uruhu rusa nkuruhu nyarwo, cyangwa rufite ingaruka zihariye.

4. Nyuma yo kuvurwa: Nyuma yo kurangiza gutunganya, uruhu rwa PU rushobora gukenera kurwara intambwe nyuma yo kuvura, nko kurinda amata atatanga amazi, nibindi, byongera iherezo ryayo nibiranga.

5. Kugenzura ubuziranenge no kwipimisha: Mubyiciro byose byo gutanga umusaruro, kugenzura ubuziranenge no kugenzura bizakorwa kugirango ihuze uruhu rwuruhure kandi rusabwa ibisabwa.

Igikorwa cyo gutanga umusaruro wa PU Uruhu:

1. Kusanya no gusubiramo imyanda ya Polyurethane, nkibicuruzwa bya kera bya PU, imyanda yumusaruro, nyuma yo gutondeka no gusukura imyanda n'umwanda, hanyuma ukore ibintu byumisha;

2. Kurambura ibikoresho bisukuye muri Polyurethane muduce duto cyangwa ifu;

3. Koresha ivanga kugirango uvange ibice bya Polyurethane cyangwa ifu ya Polyurethane, filers, Antioxiders, Antioxiders, nibindi., Hanyuma ubishyire mubikoresho byo gushyushya kugirango bibe matrix nshya Polyurethane. Matrix polyethane noneho ikorerwa muri firime cyangwa imiterere yagenwe yo guta, guhinga cyangwa kubungabunga.

4. Ibikoresho byakozwe birashyushye, bikonje kandi bikizwa kugirango hakemure imitungo n'imiti yimiti.

5. Yakize pu uruhu, rwinjiye, rwanditse, rurangishwa no kuvura hejuru kugirango ubone isura yifuzwa;

6. Kora ubugenzuzi bwiza kugirango byujuje ubuziranenge nibisabwa. Noneho ukurikije ibisabwa byabakiriya, gabanya muburyo butandukanye nuburyo bwuzuye uruhu rwarangiye;

Binyuze mu buryo bweruye, birashobora kumvikana ugereranije n'uruhu gakondo rwa PU, Uruhu rwa PU rwita cyane ku kurengera ibidukikije no gutunganya ibikoresho byo gutunganya ibidukikije, kugabanya umwanda w'ibidukikije. Dufite ibyemezo bya GRS kuri PU na PVC, bikaba byita ku iterambere rirambye no kurengera ibidukikije, kandi imyitozo yo kubyaza.
