Kuki ibimenyetso byumuhanda bihinduka umuhondo? Uruhare rwa UV & Resin ikirere

Kumenyekanisha umuhanda biterwa cyane cyane na UV gutesha agaciro kandi usukuye ikirere, uteshutse no kubara. Dore uko bakorana:

1. Uv ibyangiritse
Imirasire yizuba (UV) rays igabanya imiti yimiti mubikoresho biranga. Kubiranga my Ibimenyetso byera hamwe na titanium yo hasi (tio₂) gutakaza igikundira vuba, nka tio₂ ingabo irwanya uv ariko degrade mugihe.

2. Resin ikirere
Ibishishwa bya thermoplastique biroroshye ku bushyuhe bwinshi (180-230 ° C), kwihuta. Kurenza urugero mugihe cyo gusaba cyangwa kurasa byizuba byihuta byangiza resin gutesha agaciro, biganisha kumuhondo.
Aromatic TPU resins (ikoreshwa mubice bimwe) ikunda uv-itera umuhondo utera uv-yashizwemo inzego za bengene, bitandukanye na aliphatic tpu.
Ibisubizo
Ongeraho UV AVorbers (urugero, ibice bya BenzotriaZole) kugirango uhagarike, guhagarika 270-38nm uv rays.
Koresha resion nziza cyane hamwe na tio₂ ihagije (≥18%) kugirango wongere uv irwanya.
Kugenzura ubushyuhe bwo gusaba (180-200 ° C) kugirango wirinde kwangirika.
Mugukemura uv kandi resin ituje, ibimenyetso byumuhanda birashobora kugumana ibara nigikorwa igihe kirekire.
