Impamvu imashini zikoresha polyurethane zidakomeza igihe kirekire iyo zisigaye

Akenshi abakiriya batubaza ko ibikoresho bya polyurethane byashyizwemo igihe kirekire, birasaza, byoroshye kubyangiza n'ibindi bintu, mu by'ukuri iki si ikibazo cya polière, ni ibintu bisanzwe.

Ubwa mbere, impamvu zo gusaza kw'ibice bya polyurethane
Impamvu zituma imiterere y’urumuri rwa polyurethane isaza ziratandukanye. Muri rusange, impamvu nyamukuru zituma imiterere y’urumuri rwa polyurethane isaza zirimo oxidation, imirasire ya ultraviolet, ubushuhe, ubushyuhe bwinshi, ubushyuhe buke, imiti ivangavanze n’ibindi bintu bidukikije, ndetse n’uruhererekane rwa molekile rwa polymer rw’imiterere yayo n’ubudahangarwa bwa shimi n’ibindi bintu.

Icya kabiri, ingaruka zo gusaza za polyurethane caster
Kugendana n'ubusaza bwa polyurethane caster, imiterere yayo ifatika n'iya shimi izahinduka, ikagaragara nk'ibara ryijimye, gucika kw'ubuso, kugabanuka k'ubukana, kugabanuka k'ubudahangarwa. Uko urwego rw'ubusaza rugenda rwiyongera, imikorere y'ibice bya polyurethane caster izagenda itakaza imikorere, amaherezo bigatera kwangirika kw'ibikoresho. Mu bikorwa bifatika, nko gufunga ibikoresho by'ubwubatsi, ibikoresho by'uruhu rw'ubukorano, intebe z'imodoka n'ibindi, ibice bya polyurethane caster bishobora guteza akaga gashobora guterwa n'umutekano.

Icya gatatu, niba gusaza kwa polyurethane bizatuma ibintu byoroha
Nyuma yo gusaza kwa polyurethane caster, ubukana n'ubudahangarwa bw'ibikoresho biragabanuka, bishobora gutuma ibintu byoroha, ariko iyi si yo nzira yonyine yo kugaragaza gusaza. Urugero, kugabanuka k'imiterere yo gukanda kw'ibikoresho bya polyurethane caster bishobora gutuma ibikoresho bihinduka. Birumvikana ko ibimenyetso by'imikorere nk'ubukana n'ubudahangarwa bw'ibikoresho bya polyurethane caster bihinduka mbere na nyuma yo gusaza, iki kikaba ari kimwe mu bimenyetso by'ingenzi byerekana urwego rwo gusaza kw'ibikoresho.
