Ukonyusa Njani uKunyangwa koMkrwelo weeMpahla ezicacileyo zeMoto

Indlela entsha yokwandisa ukuchasana nokukrala kweedyasi ezicacileyo zemoto

Iqela labaphandi baseIran kutshanje beza nendlela entsha yokunyusa ukuxhathisa kwengubo ecacileyo yemoto.

Kumashumi eminyaka akutshanje, kuye kwakho inzame enkulu yokuphucula ukuxhathisa kweedyasi ezicacileyo zemoto ngokuchasene nokunxiba okugrumbayo kunye nokudilika. Ngenxa yoko, kuye kwacetywa iindlela ezininzi zobuchule kule njongo. Umzekelo wamva nje walo mva ubandakanya ukusetyenziswa kwezongezo ezisekelwe kwi-silicon ukunika ngcono umgangatho wokuchasa ukukrwela kwiindawo ezisetyenzisiweyo.

Abaphandi baye bakwazi ukudibanisa i-40 nm eguqulelwe kwi-silica nanoparticles kwi-acrylic / melamine ecacileyo-coat ukufumana ukuphakama ngokubhekiselele kwi-scratch resistance. Ukongeza kwaye njengenxalenye encedisayo kwisifundo sabo, baye baseka indlela entsha yokuphanda i-morphology yokukrala kunye neempawu ngokusebenzisa i-gonio-spectrophotometry.

Ngokweziphumo zolu phando lovavanyo, ukuphunyezwa kweengqungquthela ze-nano-size kuvumela ukufezekiswa kweedigri eziphezulu zokuphucula kwiipropati xa kuthelekiswa nezongezo eziqhelekileyo ezisekelwe kwi-silicon. Ngamanye amazwi, i-nanoparticles yayiza kuba nefuthe kwinkqubo yokunyanga yokugqoka kwaye yenze i-particle / i-coating yenethiwekhi yomzimba echasene ne-scratches.

Ngokusekelwe kuphando olwenziwayo, ukongezwa kwe-nanoparticles akugcini nje ukwandisa ubunzima, i-elasticity modulus, kunye nokuqina kwengubo kodwa kunciphisa ubuninzi benethiwekhi yayo kwaye iguqule i-morphology ye-scratch ukusuka kuhlobo lwe-fracture ukuya kuhlobo lweplastiki (ikhono lokuziphilisa). Ngenxa yoko, olu phuculo ludibene luzisa ukuqina ekusebenzeni kweedyasi ezicacileyo zemoto kunye nokunceda ukugcina inkangeleko yazo ebonakalayo.
