Nyob rau hauv lub ntiaj teb no ntawm kev ntsuam xyuas cov ntaub ntawv, tshwj xeeb tshaj yog coatings thiab pleev xim rau, kev nkag siab abrasion kuj yog ib qho tseem ceeb heev. Qhov no yog qhov chaw kuaj kev puas tsuaj (tseem hu ua cov tshuab kuaj hnav lossisabrasive xeem tshuab) tuaj rau hauv. Cov tshuab no yog tsim los ntsuas cov khoom muaj peev xwm tiv taus kev sib txhuam thiab hnav, uas yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kav ntev ntawm ntau yam khoom.
ASTM (American Society for Testing and Materials) tau tsim ntau yam qauv coj los kuaj kev puas tsuaj. Ob tus qauv tseem ceeb yog ASTM D2486 thiab ASTM D3450, uas tsom mus rau qhov sib txawv ntawm kev kuaj kev puas tsuaj.
Cov qauv ASTM feem ntau yuav siv tau rau koj qhov kev kuaj puas muaj xws li:
ASTM D 2486 Cov khoom siv- Qhov no yog tus qauv ntsuas ntsuas qhov tsis kam ntawm cov xim rau kev yaig los ntawm kev txhuam.
ASTM D 3450 Cov Lus Qhia- Qhov no yog tus qauv xeem txoj kev rau washability khoom ntawm sab hauv architectural txheej.
ASTM D 4213 Cov khoom lag luam- Qhov no yog ib qho qauv qauv ntawm kev sim cov tshuaj txhuam hniav ntawm cov xim los ntawm kev puas tsuaj hnyav.
ASTM D 4828 Cov khoom lag luam- Qhov no yog tus qauv xeem txoj hauv kev rau kev ua tau zoo ntawm cov organic coatings.
ASTM F1319 Cov Lus Qhia- Qhov no yog ib txoj kev sim ntsuas uas piav qhia txog tus txheej txheem rau kev txiav txim siab npaum li cas ntawm cov duab xa mus rau saum npoo ntawm daim ntaub dawb los ntawm kev txhuam.
ASTM D2486 yog tus qauv tshwj xeeb tsim los ntsuas qhov kev tiv thaiv ntawm cov coatings los txhuam corrosion. Qhov kev sim no yog qhov tseem ceeb tshwj xeeb rau cov neeg tsim khoom pleev xim thiab txheej vim nws simulates qhov hnav thiab tsim kua muag uas tshwm sim hauv kev siv tiag tiag. Qhov kev sim no suav nrog kev ua kom lub ntsej muag coated rau kev txhuam (feem ntau nrog cov khoom siv abrasive) los txiav txim siab lub peev xwm los tiv thaiv kev puas tsuaj. Cov txiaj ntsig tau muab kev nkag siab zoo rau kev ua haujlwm ntev ntawm cov txheej txheem, pab cov tuam ntxhab txhim kho cov qauv thiab ua kom lawv cov khoom ua tau raws li cov neeg siv khoom xav tau.
ASTM D3450, ntawm qhov tod tes, deals nrog lub washability ntawm sab hauv architectural txheej. Cov qauv no yog qhov tseem ceeb rau kev soj ntsuam seb qhov chaw tuaj yeem ntxuav tau yooj yim npaum li cas yam tsis muaj kev puas tsuaj rau txheej txheej. Kev ntsuam xyuas suav nrog kev siv cov tshuaj ntxuav tshwj xeeb thiab txhuam qhov saum npoo los ntsuas cov txheej txheem tiv thaiv kev puas tsuaj thiab nws lub peev xwm los tswj nws qhov zoo li lub sijhawm. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov coatings siv nyob rau hauv cov chaw tsheb loj lossis qhov chaw uas yuav tsum tau ntxuav tas li, xws li chav ua noj thiab chav dej.
Ob leeg ASTM D2486 thiab ASTM D3450 hais txog qhov tseem ceeb ntawm kev siv tus ntsuas kev puas tsuaj los ua qhov kev xeem no kom raug. Cov tshuab no tau nruab nrog ntau yam ntawm cov yam ntxwv los tswj cov kev sim ntsuas, ua kom ntseeg tau thiab rov ua tau zoo dua. Los ntawm kev siv ibabrasive xeem tshuab, manufacturers tuaj yeem nkag siab tob txog qhov kev ua tau zoo ntawm lawv cov khoom thiab txiav txim siab paub txog kev hloov kho lossis kev txhim kho cov khoom.
Ntxiv nrog rau cov qauv ASTM no, kev siv cov tshuaj txhuam hniav tsis txwv rau cov xim thiab cov txheej txheem. Kev lag luam xws li automotive, aerospace, thiab kev tsim kho kuj vam khom rau kev kuaj kev puas ntsoog los ntsuas qhov ua tau zoo ntawm cov khoom siv hauv lawv cov khoom. Piv txwv li, cov tshuab no tuaj yeem siv los ntsuas qhov ua tau zoo ntawm cov txheej txheem tiv thaiv ntawm lub tsheb lossis kev hnav tsis kam ntawm cov ntaub ntawv hauv pem teb kom ntseeg tau tias lawv ua tau raws li cov qauv kev lag luam thiab cov neeg siv khoom xav tau.
ASTMKev kuaj kev puas tsuaj, tshwj xeeb tshaj yog ASTM D2486 thiab ASTM D3450, ua lub luag haujlwm tseem ceeb hauv kev ntsuam xyuas qhov ua tau ntev ntawm cov xim thiab cov txheej txheem. Siv lub tshuab kuaj abrasion yog qhov tseem ceeb rau kev ua cov kev ntsuam xyuas no kom zoo, muab cov neeg tsim khoom nrog cov ntaub ntawv lawv xav tau los txhim kho lawv cov khoom. Raws li kev lag luam tseem ceeb tshaj qhov ua tau zoo thiab kev ua haujlwm ntev, qhov tseem ceeb ntawm kev kuaj kev puas tsuaj tsuas yog nce ntxiv, ua rau cov qauv no thiab cov tshuab ntsuas cov cuab yeej tseem ceeb hauv cov khoom siv science thiab engineering.
