1. Cov kuab tshuaj-raws li txheej: Cov txheej txheem no suav nrog kev siv cov kuab tshuaj-raws li txheej rau TPU nto thiab tso cai rau cov kuab tshuaj kom evaporate thaum ziab, ua rau cov txheej txheej tsis sib xws. Cov kuab tshuaj-raws li txheej yog tus nqi- siv tau yooj yim thiab siv tau; lawv muab cov khoom sib xws nrog kev hnav thiab kev tiv thaiv corrosion, ua rau lawv xaiv los tiv thaiv TPU cov khoom.
2. Electroplating: Electroplating yog txheej txheem uas siv cov hluav taws xob tam sim no thiab cov hlau ions kom tso cov txheej hlau rau ntawm TPU nto. Nws txhim kho qhov hnav tsis kam, tiv thaiv corrosion, thiab zoo nkauj rov hais dua. Txawm li cas los xij, electroplating entails tus nqi siab dua thiab muaj peev xwm txwv txog txheej thickness; Tsis tas li ntawd, kev kho dej khib nyiab yuav tsum tau xav txog.
3. Nplaim oxidation txheej: Cov txheej txheem no suav nrog kev txau cov nplaim hluav taws kub - kub mus rau TPU nto kom induce oxidation thiab tsim txheej txheej. Thaum cov txheej txheem ceev yog siab, lub durability ntawm txheej yuav raug txwv, yuav tsum xaiv cov ntaub ntawv txheej tsim nyog raws li qhov tshwj xeeb daim ntawv thov ib puag ncig.
4. Vapor deposition txheej: Vapor deposition yog txheej txheem uas gaseous tebchaw tso rau ntawm TPU nto los ua ib tug nyias zaj duab xis. Cov txheej txheem no tsim cov txheej txheem nrog cov khoom tshwj xeeb- xws li hnav tsis kam lossis dej tsis kam- ntawm TPU nto. Nws yuav tsum muaj cov cuab yeej tshwj xeeb thiab kev txawj ntse tshaj lij, uas ua rau cov nqi qis dua.
