Nws lub hauv paus yog luv lub sijhawm ua tiav ib pawg los ntawm cov khoom ntws.

Cov txiaj ntsig:

• Kev Ua Haujlwm Zoo Tshaj Plaws: Yog tsis muaj kev cuam tshuam hluav taws xob, cov ntaub ntawv txuas ntxiv mus hauv lub cub tawg, txo lub sijhawm ua tiav ib pawg mus rau ob peb teev mus rau hnub.
• Kev Siv Hluav Taws Xob Tsawg: Los ntawm kev ua kom zoo tshaj plaws kev siv cua sov thiab txo qis cov voj voog cua sov uas tsis tseem ceeb, kev siv hluav taws xob ntawm cov khoom lag luam raug txo qis.
• Khoom Zoo Ruaj Khov: Kev tswj hwm thaj chaw kub thiab txias txo qhov kub hnyiab lossis tsis kub txaus, ua kom cov khoom sib xws.

Qhov Tsis Zoo:

• Cov Khoom Siv Nyuaj Siab: Yuav tsum tau tswj hwm qhov nrawm ntawm cov khoom siv, qhov chaw faib tawm ntawm thaj chaw kub, thiab lwm yam kev ntsuas kom meej, ua rau muaj qhov ntsuas siab.
• Kev Nqis Peev Thaum Pib Siab: Tus nqi tsim kho ntawm cov kab ntau lawm tas mus li yog siab dua li cov khoom siv ib txwm muaj.

III. Lub Tshuab Sib Tsoo Zoo (Cov Khoom Siv Pabcuam)

Lub Ntsiab Cai:
Lub tshuab sib tsoo ultrafine siv kev sib tsoo ceev ceev, shearing, thiab extrusion los ua kom cov roj av coke graphitized ua cov khoom me me micron (piv txwv li, 200 mesh), ua tau raws li qhov yuav tsum tau ua rau cov khoom me me rau cov ntawv thov tshwj xeeb xws li cov roj hmab ntxiv.

Cov txiaj ntsig:

• Kev Tswj Qhov Loj Me Me Uas Tseeb: Nws tuaj yeem tsim cov hmoov zoo heev txij li 0.001-0.1 hli, ua kom tau raws li kev xav tau ntawm kev ua lag luam siab.
• Tsim Kev Hnav Qis: Siv cov khoom siv superhard alloy rau kev sib tsoo rauj thiab cov nplhaib iav ua rau lub neej ntawm cov khoom siv ntev dua.
• Kev Siv Tshuab Siab: Kev sib xyaw ua ke ntawm kev faib tawm thiab kev sau cov txheej txheem txo qhov kev cuam tshuam ntawm tes, txhim kho kev ruaj khov ntawm kev tsim khoom.

Qhov Tsis Zoo:
