I. Impamvu ikoranabuhanga rya Polyurethane ari ingenzi mu bwubatsi bwa none ku isi
Ibifunga bya polyurethane (PU) n'ibifunga bya kole byabaye ibintu by'ingenzi mu bwubatsi, inganda, n'ibikorwa remezo. Uko amahame y'ubwubatsi ku isi akomeje kwiyongera—bisaba ubushobozi bwo kugenda neza, igihe kirekire cyo gukora, kurwanya ikirere, no guhuza neza n'ibintu bitandukanye—ikoranabuhanga rya PU ritanga ubushobozi bwo koroshya ibintu, gukomera no kuramba ugereranije n'ibindi bikoresho bisanzwe bifunga ibintu.
Mu bidukikije birimo imihangayiko myinshi nko ku nkuta ndende, inyubako za sima zakozwe mbere, imashini z'inganda, ibikoresho byo gutwara abantu n'ibintu, ndetse n'ubuhanga bwo mu mazi, sisitemu za polyurethane zitanga uruvange rwaUburimbane bwinshi, gufatana igihe kirekire, gukomera kwa mashini, no kurwanya imihindagurikire y'ikirereibyo bituma ziba nziza cyane ku bijyanye n'ibikenewe mu ikoranabuhanga rigezweho.
Siway, ikigo mpuzamahanga cy’inganda zikoraibifunga bya polyurethane, kole za PU, ifuro rya PU, n'imyambaro ya PU idakingirwa n'amazi, itanga ibikoresho bigezweho bikoreshwa mu bihugu birenga 60. Hamwe n'uruvange rwaUbushobozi bwo gukora ubushakashatsi n'iterambere, serivisi za OEM, ibyemezo by'ubuziranenge mpuzamahanga, n'ubushobozi bwo gukoraSiway itanga ibisubizo bya polyurethane ku mishinga minini y’ubuhanga, abakora façade, abakora imodoka, ndetse n’imiyoboro y’inganda ku isi yose.
II. Ubumenyi bw'ibifunga bya Polyurethane: Ni iki gitandukanya PU?
Sisitemu za PU zo mu rwego rw'umwuga zituruka muri Siway zishinzwe:
-
--Ubushobozi bwo kugenda cyane (± 20% kugeza ± 50%)
-
--Gukira nyuma yo gukanda cyangwa kongera igihe
-
--Kurwanya umunaniro mwinshi ukabije
-
--Gukingira umuyaga n'ingaruka zawo
Ibi bituma baba amahitamo meza kuri:
-

Uburyo bwo gusimbuza butanga kandi uburyo bukomeye bwo gufatana ku bintu bifite imyenge nka sima n'amabuye, bigatuma PU irushaho kuba nziza kurusha izindi sealant.
2. Gukomera, Kugarura Ubuyanja, no Gukorana neza kw'Imikoranire
Ibifunga bya PU byakozwe kugira ngo bikurure imiterere y'inyubako bidacika cyangwa ngo bibure gufatana.
3. Imikorere igereranya ugereranije na Silicone, MS, na Acrylic Sealants
| Umutungo | Polyurethane (PU) | Silikoni | MS Polymer | aruleri |
|---|---|---|---|---|
| Imbaraga za mekanike | Hejuru | Hagati | Hagati-hejuru | Hasi |
| Ubudahangarwa bw'ingufu | Byiza cyane | Intege nke | Hagati | Intege nke |
| Gusiga irangi | Yego | No | Igice | Yego |
| Ingano y'ubushyuhe | –40°C kugeza +90°C | –50°C kugeza +150°C | Hagati | Iringaniye |
| Gufata kuri beto | Icy'ikirenga | Hafi | Byiza | Hafi |
| Imikoreshereze y'inyubako | Imiterere y'igice | Inyubako (silicone) | Ibidashingiye ku miterere | No |
Ibifunga bya PU bitanga uruvange rwagukomera kwa mekanike, imikorere y'ingendo, naubwiza bw'ubutakantagereranywa n'izindi shimi.
