Kev txhais thiab yam ntxwv ntawm cov hlau txheej

Cov txheej txheem hlau yog ib hom tshiab ntawm cov khoom siv uas muaj cov txheej txheem qis- melting- taw tes, qis- cov khoom siv tawv tawv yog coated rau saum npoo ntawm qhov siab - hardness, siab - lub zog hlau khoom. Lub thickness ntawm txheej txheej yog feem ntau ntawm 1-5 mm. Cov yam ntxwv tseem ceeb ntawm cov hlau txheej yog raws li nram no:

High Hardness: Cov txheej txheej hlau muaj siab hardness, tiv taus hnav thiab khawb, yog li txhim kho lub neej kev pab cuam ntawm cov khoom hlau.

Lub zog muaj zog: Cov txheej txheej hlau muaj lub zog siab, ua kom cov khoom thauj -cov kabmob muaj peev xwm thiab tensile lub zog ntawm cov khoom hlau, txhim kho nws cov kev ua tau zoo.

Zoo Corrosion Resistance: Cov txheej txheej hlau muaj qhov zoo corrosion kuj, zoo tiv thaiv corrosion thiab puas los ntawm corrosion.

Kev ua tau zoo sealing: Cov txheej txheej hlau muaj kev sib khi zoo, tiv thaiv kev tawm hauv cov khoom hlau.
