Maitiro Ekuwedzera Kukwenya Kupokana kweMotokari Clear Coats

Iyo Nyowani nzira yekuwedzera kukwenya kuramba kwemajasi akajeka emotokari

Chikwata chevaongorori veIran munguva pfupi yapfuura vauya nenzira nyowani yekuwedzera kuramba kwekupokana kwemajasi akajeka emotokari.

Mukati memakumi emakore achangopfuura, pakave nekuedza kukuru kwekuvandudza kuramba kwemajasi emotokari akajeka achipokana neabrasive uye erosive kupfeka. Nekuda kweizvozvo, huwandu hwehunyanzvi hwakarongwa hwechinangwa ichi. Muenzaniso wezvino wekupedzisira unosanganisira kushandiswa kwesilicon-based additives kupa zvirinani anti-scratching quality kune yakashandiswa nzvimbo.

Vatsvakurudzi vakakwanisa kubatanidza 40 nm yakagadziridzwa silica nanoparticles mu acrylic / melamine clear-coat kuti vawane hukuru maererano nekurambana. Pamusoro pezvo uye sechikamu chechikamu chekudzidza kwavo, vakagadzira hurongwa hutsva hwekuongorora morphology nehunhu kuburikidza negonio-spectrophotometry.

Zvinoenderana nemhedzisiro yeiyi tsvakiridzo yekuyedza, kuitiswa kwenano-saizi zvimedu zvinoita kuti kubudirira kwepamusoro madhigirii ekuvandudza mumidziyo zvichienzaniswa neyakajairwa silicon-based additives. Mune mamwe mazwi, iyo nanoparticles yaizopesvedzera nzira yekurapa yekupfekedza uye kugadzira zvidimbu / kupfekedza network network iyo inopokana nekukwenya.

Kubva pane tsvakurudzo yakaitwa, kuwedzerwa kwe nanoparticles hakungowedzere kuoma, elasticity modulus, uye kuoma kwechifukidzo asi zvakare kunoderedza kusimba kwayo kwetiweki uye kunoshandura scratch morphology kubva kumhando yekuputsika kuenda kumhando yepurasitiki (kuzviporesa). Nekuda kweizvozvo, kuvandudzwa uku pamwe chete kunounza kusimba mukuita kwemotokari akajeka-majasi uye anobatsira kuchengetedza chitarisiko chavo.
