Lub hom phiaj thiab qhov tseem ceeb ntawm kev ua cov ntaub nyoos hauv kev tsim cov ntaub abrasive

Nws yog ib qho tseem ceeb uas yog qhov zoo ntawm daim ntaub qub, lub ntsiab substrate ntawm cov abrasive siv, ua tau qee yam, tab sis nws kuj yog qhov tseem ceeb kom nws kho kom zoo. Lub hom phiaj ntawm daim ntaub thawj kev kho ntaub yog rau:

(1) Txhim kho qhov adhesion ntawm lub hauv ntej ntawm daim ntaub qub thiab cov xuab zeb-bonding txheej, uas yog, sau lub qhov nyob rau hauv daim ntaub los tiv thaiv lub hauv paus kua nplaum thiab ob lub kua nplaum los ntawm nkag mus rau hauv lub hauv paus khoom nyob rau hauv loj qhov ntau.

(2) Txhim kho lub tiaj tiaj thiab txuas ntxiv ntawm daim ntaub thawj ua kom cov kua nplaum-coated xuab zeb cog cov khoom sib txawv, uas yog qhov tshwj xeeb tshaj yog rau cov xuab zeb zoo nkauj. Lub tiaj ntawm cov khoom siv hauv paus tsis txhais tau tias smoothness. Cov ntawv pov thawj du thiab cov nplaum ntawm cov xuab zeb-khi txheej yog qhov me me, thiab txoj kev rov qab yuav ua rau plam lub sijhawm ua haujlwm, uas tsis xav.

(3) Ua kom lub hauv paus khoom ruaj khov, nruab nrab ntawm hardness thiab softness, txo elasticity thiab extension, thiab txhim kho tensile zog.

(4) Muab cov ntaub ntawv hauv paus rau cov roj thiab dej tsis kam, uas yog qhov tseem ceeb tshwj xeeb rau cov xuab zeb-resistant.

(5) Txhim kho cov tsos zoo ntawm cov khoom.
