Irangi rya Polyurethane rirwanya ingese rishingiye ku mazi ry’umwuga

*Imiterere y'ibicuruzwa:

Irangi rya polyurethane rirwanya kwangirika rishingiye ku mazi ni irangi rigizwe n'ibice bibiri birimo resin ya polyurethane ituruka mu mazi, amarangi arwanya ikirere, inyongeramusaruro zitandukanye, n'umuhondo uturuka ku mazi, rifite ubushobozi bwiza bwo kurwanya kwangirika kandi ririnda ibidukikije. Iki gicuruzwa gifite VOC nkeya cyane, cyujuje ibisabwa bigezweho byo kurengera ibidukikije mu gihe gitanga imikorere yo kurinda nk'uko irangi risanzwe rikoreshwa mu gushonga.

*Ibiranga Ibicuruzwa:

● Gukoresha amazi nk'amazi asukura, atagira impumuro, adahumanya, adatwika kandi ntaturika.

● Ubudahangarwa bw'umuhondo, budahangarwa n'ikirere, ubwiza n'amabara bigumana neza.

● Irabagirana cyane kandi irabyibushye neza.

● Gufata neza cyane, gukomera cyane, no kudashira cyane.

● Amazi meza cyane, amavuta, imiti ishongesha ndetse n'imiti irwanya cyane.

● Irwanya ubushyuhe n'ubushuhe ndetse n'umunyu uterwa neza.

*Ikoreshwa ry'ibicuruzwa:

Amarangi ya polyurethane akoreshwa mu mazi akoreshwa cyane mu makoti yo hanze afite isura nziza, nko mu mashini, mu matangi yo kuvanga, mu biraro, mu matangi yo kubikamo ibintu, mu masanduku, mu bwato, cyane cyane mu modoka. Ashobora kandi gukoreshwa mu mavuta ya pulasitiki, atanga amabara n'uburinzi ku bicuruzwa bya pulasitiki nk'udusanduku tw'ibikoresho by'ikoranabuhanga, ibikinisho, n'ibikoresho byo mu rugo.

*Amakuru ya tekiniki:

*Ubuvuzi bw'ubuso:

Kugira ngo habeho gufatana kw'urushundura no kurinda ingese igihe kirekire, ubuso bw'urushundura bugomba gusukurwa neza amavuta, ingese, ingano, irangi rishaje n'imyanda idafite ishingiro mbere yo gukoresha. Amabwiriza yo gutegura agomba kuba yujuje ibi bikurikira::

Ubuso bwose bugomba gusigwa bugomba kuba busukuye, bwumye kandi budafite umwanda. Mbere yo gusiga irangi, ubuso bwose bugomba kuba bukurikije ISO_{8504: 2000}isuzuma n'itunganywa bisanzwe.

Icyuma gikozwe mu gipimo cyaturikijwe kuri Sa_2.5urwego, ubukana bw'ubuso ni 30-75μm, cyangwa byakuwemo ibinyampeke, byakuwemo kandi bitavamo umwuka;

Icyuma kidafite okiside cyaturikiye muri Sa_2.5urwego, cyangwa se irangi ryakozwe kugeza kuri St₃urwego rufite umugozi wo gusya ukoresheje umwuka cyangwa amashanyarazi;

Ibyuma bisizwe irangi rya primer yo mu nzu byangiritse, ingese n'ingufu z'umweru kuri primer ya zinc powder bigomba gukurwaho ingese kabiri, ingese z'umweru zigakurwaho hanyuma zigashyirwa kuri St.₃.

Ibindi bicuruzwa Iki gicuruzwa gikoreshwa ku bindi bikoresho, nyamuneka gisha inama ishami ryacu rya tekiniki.

Ubuso buvuwe bugomba kuba busukuye, bwumutse, budafite amavuta, nta mukungugu, kandi bugasigwa irangi mu masaha 6 nyuma yo guturitsa umucanga kugira ngo hirindwe ingese ku buso.

*Imiterere y'inyubako:

Ubushyuhe bwa substrate ntiburi munsi ya 5 ℃, kandi nibura 3 ℃ iri hejuru y'ubushyuhe bw'ikirere kandi ubushyuhe buri munsi ya 85% (ubushyuhe n'ubushuhe bigomba gupimwa hafi y'substrate). Kubaka birabujijwe cyane mu gihe cy'ibihu, urubura n'umuyaga mwinshi.

*Imiterere y'inyubako:

Ubushyuhe bwa substrate ntiburi munsi ya 5 ℃, kandi nibura 3 ℃ iri hejuru y'ubushyuhe bw'ikirere kandi ubushyuhe buri munsi ya 85% (ubushyuhe n'ubushuhe bigomba gupimwa hafi y'substrate). Kubaka birabujijwe cyane mu gihe cy'ibihu, urubura n'umuyaga mwinshi.

*Intambwe zo kubaka:

Intambwe ya 1: Gutegura ubuso bw'ubutaka (IyoUrufunguzoIntambwe)

Ubwiza bw'itegurwa ry'ubuso bugena neza uburyo icyuma gifatana n'igihe kizamara irangi.

Ubuso bw'icyuma bugomba gukurwaho amavuta kandi butagira ingese (ku bipimo bya Sa2.5 cyangwa St3) kugira ngo ubuso bw'icyuma bugomba gusigwa irangi bube busukuye neza, bwumye rwose, kandi budafite umwanda nka amavuta, amavuta, umukungugu, umunyu, igipimo, n'irangi rishaje ridafite ubushyuhe. Ubushuhe cyangwa ubukonje bugaragara ntibyemewe.

Ubuso bwavuwe bugomba kuba bwujuje ibisabwa mu isuku n'ubukana, kandi irangi rigashyirwa vuba bishoboka kugira ngo hirindwe ko ingese yongera kugaruka cyangwa kwanduzwa n'ibindi.

Intambwe ya 2: Shyiraho Primer

Kugira ngo urebe ko byangiza neza, tanga igitekerezo cy'umuti 1 urwanya ingese, ushobora kunoza gufatana kw'ubutaka kandi ufite ubushobozi bwiza bwo kurinda ingese.

Intambwe ya 3: Shyira irangi rya poliyuretani rishingiye ku mazi

Nyuma yo gufungura indobo, kangura neza ukoresheje amashanyarazi kugeza igihe ibara n'ubushyuhe bihuye, suka buhoro buhoro igice cya B (umuti uvura) mu gice cya A (irangi), neza ukurikije igipimo cyagenwe (ukurikije uburemere). Nyuma yo kuvanga burundu, reka imvange ihagarare iminota 5-10 kugira ngo ikure. Hanyuma imvange ivanze ikoreshwe mu masaha 4 (igihe cyo kuyikoresha mu nkono). Hanyuma woze/uyizungurutse cyangwa uyitere, gutera umwuka udafite umwuka bitanga umusaruro mwiza kandi bitanga ubwiza bwiza bwa firime y'irangi. Niba ufite ibikoresho by'umwuga n'ubuhanga, bizaba byiza cyane. Ikoreshwa ry'irangi ry'abahanga ni 0.2kg/m²/coat. (Ikoreshwa nyaryo rishobora gutandukana bitewe n'imiterere y'ubuso, imiterere y'ubuso, uburyo bwo kuyikoresha n'uburyo bwo kuyikoresha.)

*Niba bikenewe koroshya, shyiramo amazi yakuwemo iyoni hakurikijwe ubukana n'uburyo bwo kuyikoresha (gusukura, kuyizunguza, cyangwa kuyitera). Hindura ubukana kugira ngo bujyane n'uburyo bwihariye bwo kuyikoresha.

* Igipimo cyo gushonga cya 5-20% ukurikije uburemere. Kugabanya cyane bizagira ingaruka mbi ku miterere ya firime, imbaraga zo guhisha, no kuramba kwayo igihe kirekire.

* Mbere yo gushyiramo agapira gakurikira, menya neza ko agapira kabanje kakize neza, gasukuye, kumutse, kandi nta bihumanya byose byandujwe.

* Irinde gukangura cyane kugira ngo wirinde ko habaho uduheri twinshi.

* Intera yo kongera gusiga: Mu bidukikije byangiza gahoro gahoro: agapira 1 k'umukara + agapira 2 k'umukara + agapira 2 k'umukara; mu bidukikije byangiza cyane, ongera ubugari bw'agapira.

*Uburyo bwo kubaka:

Gutera: Gutera umwuka cyangwa gutera umwuka. Ni byiza gukoresha umuti utera umwuka udafite umwuka mwinshi.

Gusukura/Gutemba: Ubugari bwa firime yumye bugomba kugerwaho.

*Ibikwiye kwitabwaho:

▶ Ubushyuhe bw'inyubako ni 5℃-35℃ (Impinduka zihariye zikorwa hakurikijwe imiterere y'ibicuruzwa, ubushuhe ni ≤80%.

▶ Gufata umwuka mwiza kugira ngo byoroshye guhumeka kw'ubushuhe no gusiga irangi.

▶ Irinde gukonjesha mu gihe cyo kubika.

▶ Ibikoresho byo kurinda bigomba kwambarwa mu gihe cyo guturitsa umucanga

▶ Igihu, imvura, urubura, umuyaga n'imvura birabujijwe cyane kubaka.

*Kubika no Kwikorera:

▅ Bika mu bubiko bw'inzu bukonje, bwumye kandi bufite umwuka mwiza, ku bushyuhe buri hagati ya 5-35 ℃, wirinde konjesha n'izuba ryinshi;

▅ Igihe cyo kubaho ni amezi 12. Iyo ibicuruzwa birengeje igihe cyo kubibika bishobora gukoreshwa nyuma yo kubikora.

*Pake:

Irangi: 20kg/indobo, Icyuma gikingira/gitanga umuti: 4Kg/indobo cyangwa uhindure
