Umuyoboro wa Polyurethane
Umuyoboro wibyuma bya polyurethane nigicuruzwa kinini cyihanganira kwambara, gikoreshwa cyane mumiyoboro itunganya amabuye y'agaciro hamwe no gukwirakwiza imirizo.Sitasiyo y’amavuta y’ibinyabuzima ikoresha umuyoboro wa sisitemu yo gukuraho amakara n’ivu, ndetse no mu nganda za peteroli, imiti, sima n’inganda.
Ibiranga
1. Kwambara
2.Kwirinda gupima
3. Kurwanya ruswa
4. Kurwanya gusaza hydrolysis
5. Ubuhanga bukomeye
6. Kurwanya Amashanyarazi
7. Kwisiga amavuta
Arex ihitamo premium master batch hamwe nano-yahinduwe kugirango imbaraga zumurimo wa polyurethane.Ituma polyurethane itondekanya ibicuruzwa bifite imiterere ihamye ya chimique kandi ikerekana guhuza n'imiterere yabyo.
Polyurethane itondekanya umuyoboro w'icyuma, nk'imwe mu ipatanti yo mu gihugu ikomoka mu bucukuzi bw'amabuye y'agaciro muri Arex, irazwi kandi ikoreshwa n'abakiriya bacu bacukura amabuye y'agaciro.
Kugereranya imitungo hagati ya polyurethane isanzwe na nano yahinduwe na polyurethane
