1. Teflon nonstick lauj kaub.
Teflon yog cov ntawv sau npe ua lag luam siv los ntawm DuPont ntawm cov khoom lag luam fluoropolymer. DuPont tau txij li tsim ntau yam khoom dhau ntawm Teflon cob.
2, ceramic txheej tsis-pas lauj kaub.
Ceramics tau ua lub luag haujlwm tseem ceeb hauv kev kho dua tshiab ntawm cov lauj kaub uas tsis yog pas. Ceramics ruaj khov thiab tau sim rau ntau txhiab xyoo los ua pov thawj lawv qhov kev nyab xeeb. Siv nanotechnology los ua qhov saum npoo ntawm cov khoom sib xyaw thiab tsis ntxeem tau, kom ua tiav cov nyhuv ntawm tsis muaj nplaum.
