Tsiaj txiab yog ua los ntawm ntau yam ntaub ntawv, xws li stainless hlau, ceramics, tungsten steel, thiab lwm yam. Tsiaj txiab ua los ntawm cov khoom sib txawv muaj cov yam ntxwv sib txawv, qhov zoo thiab qhov tsis zoo.
1. Cov khoom siv stainless hlau
Stainless hlau tam sim no yog cov khoom siv feem ntau siv rau tsiaj txiab. Nws yog dav siv vim nws tsis yooj yim rau xeb, yooj yim los ntxuav, thiab pheej yig. Muaj ntau ntau yam khoom siv stainless hlau. Judging los ntawm hardness ntawm stainless hlau, 440C stainless hlau yog tam sim no feem ntau siv.
2. Cov khoom siv ceramic
Cov khoom siv ceramic yog suav hais tias yog cov khoom siv zoo tshaj plaws rau cov tsiaj txhu vim nws qhov hnyav thiab tsis kam hnav thiab tsim kua muag. Txawm li cas los xij, cov ntaub ntawv ceramic yog qhov nyuaj rau kev tsim khoom thiab kim dua, yog li koj yuav tsum tau ceev faj ntau dua thaum siv lawv los tiv thaiv kev sib tsoo thiab ntog.
3. Cov khoom siv tungsten steel
Tungsten steel yog siv dav hauv kev tsim cov txiab tsiaj vim nws lub zog siab thiab lub neej ntev, tshwj xeeb tshaj yog thaum txiav cov khoom tawv xws li chains. Txawm li cas los xij, tungsten steel cov ntaub ntawv nyuaj ua thiab kim, thiab xav tau kev saib xyuas tsis tu ncua los xyuas kom meej lawv lub neej kev pab.
