Niaj hnub no, tsheb nres ncoo cov tuam txhab tham txog cov teeb meem ib txwm muaj ntawm cov khoom siv semi-hlau hauv cov ntaub ntawv nres.

Yuav ua li cas los txhais cov khoom siv mis ntawm cov hlau nres: suav nrog cov hmoov av hlau, muab tso rau kom nce ntxiv, roj nplua nyeem hlau thiab cov hmoov av ntawm cov hmoov av muaj kwv yees li 40%.

2. Muaj plua plav (cov dej kub tsawg).

4. Siab thermal conductivity thiab cov cua sov cua sov yuav hloov cua sov mus rau lub sijhawm kub thiab ua kom nrawm nrawm, piston ntsaws ruaj ruaj thiab xa rov qab. Lub siab thermal conductivity tsuas yog ua rau lub thermal decomposition thiab siab qhov siab qhov kub ntawm cov ntaub ntawv tsis sib haum xeeb, uas yuav ua rau cov browed ob sab phling poob lossis tawg.

5. Lub zog adhesion, tsis yooj yim rau xeb. Tom qab corrosion, cov nplaum lossis kev puas tsuaj yog ob-txheej, thiab cov hnav yog aggragentated.

Feem pua ​​ntim yog qhov tseeb kom ntev rau kev ntsuas cov khoom sib txhuam. Tsim cov qauv engoties yuav tsum ua rau cov teg num to taub cov txiaj ntsig ntawm ntau cov txiaj ntsig ntawm cov txiaj ntsig ntawm micro thiab macro function ntawm Cov ntaub ntawv sib txhuam. Tam sim no, raws li kev nkag siab ntawm tsheb nres ncoo cov tuam txhab tsim, feem ntau cov qauv tsim qauv tsim yog raws li cov zauv sib piv. Txhawm rau kom tsis txhob muaj cov ntaub ntawv tseem ceeb ntawm cov haujlwm ntawm cov khoom xyaw, nws yog qhov tsis sib haum xeeb ntawm cov khoom xyaw nrog cov khoom xyaw yooj yim thiab meej, siab time, pressure pressure, holding time and degassing time, grinding method, two layers of material, data and other factors can affect the braking function anytime and anywhere during the braking process. As regards the formulation itself, it is not correct to determine the proportions of the various ingredients by theoretical means, nor can we quickly derive direct quantitative links between the formulation and the function, which depend primarily on accumulated experience over a long period of time.
