Tsim Tus Txheej Txheem: Cov Nias Txias Txias
Cov txheej txheem no muaj kev sib xyaw ua ke cov khoom yas ntawm cov hlau. Los ntawm kev thov siab, nws flattens microscopic convex peaks ntawm workpiece nto, yog li txo qhov av roughness. Kev kub siab yog tau tshaj tawm nyob rau hauv cov pwm kab noj hniav los ua cov tshuaj tuab moulding blanks, nrog cov tswv yim suav nrog yob thiab extrusion. Nws yog qhov tsim nyog rau cov ntaub ntawv xws li Polycarbonate thiab polypropylene. Txias xovxwm yuav ua tau zoo txhim kho cov khoom siv tensile lub zog thiab Elastic Modulus.
