Kutheni le nto amanqaku eendlela ejika etyheli? Indima ye-UV kunye ne-Retin

Ukumakishwa kwendlela ityheli ngokuyintloko kubangelwa kukonakaliswa kwe-UV kunye nokuphelisa imozulu yemozulu, ukubonakala ngokubonakalayo kunye nokhuseleko. Nantsi indlela abahlangana ngayo:

1. Umonakalo we-UV
Ilanga le-Ultraviolet (UV) i-rays iqhekeza imichiza yekhemikhali kwimichiza yokumakisha. Ngophawu lwe-thermoplastic, ukuvezwa kwe-UV Ukuvezwa kwe-Oxiid Amanqaku amhlophe atatanium Dioxide (i-tio₂) yomxholo ophulukene nobumhlophe ngokukhawuleza, njenge-tio₂ izihlangu kwi-UV kodwa ithole ixesha elide.

2. Imozulu yemozulu
I-thermoplastic i-thermoplastic i-stoften kwiqondo lobushushu eliphezulu (180-230 ° C), ukukhawulezisa i-oxidation. Ukugcwala ngokugqithisileyo ngexesha lokufaka okanye ukubonakaliswa ixesha elide kuyamangalisa ukuphefumla, okhokelela kwityheli.
I-Aromatic TPU (isetyenziselwa iingubo ezithile) zithambekele kwi-UV-ye-UV-I-UVen ebutyheli ngenxa yesakhiwo se-Bezene, ngokungafaniyo ne-Aliiitic TPU ye-Aliittic.
Izisombululo
Yongeza i-Absings
Sebenzisa i-resity sulty sulty kunye ne-tio eyaneleyo (≥18%) yokuphucula ukumelana ne-UV.
Ukulawula ubushushu besicelo (180-200 ° C) ukuthintela ukonakala kwengqondo.
Ngokujongana no-UV kunye nozinzo, uphawu lwendlela lungagcina umbala kunye nokusebenza ixesha elide.
