Kev xeem nkag (PT) kuj yog ib hom kev kuaj tsis muaj kev puas tsuaj. Nws lub hauv paus ntsiab lus yog siv cov permeability zoo thiab capillary ua ntawm cov xim penetrants los yog fluorescent penetrants kom nqaim qhov khoob. Tom qab kev nkag mus, tshem tawm, thiab kho cov duab, qhov chaw tsis xws luag tau nthuav dav thiab nthuav tawm. , txhawm rau txiav txim qhov tsis xws luag, qhov chaw thiab qhov loj me. Kev ntsuam xyuas Penetrant yog siv kev tshuaj xyuas qhov muag lossis iav tsom iav kom pom qhov tsis sib xws hauv qhov qhib ntawm qhov chaw.hlau casting khoom. Txawm li cas los xij, kev ntsuas kev nkag mus tsis tuaj yeem cuam tshuam qhov xwm txheej, cov duab, qhov loj thiab qhov tob ntawm qhov tsis sib xws.
Penetrant yog cov khoom siv tseem ceeb tshaj plaws hauv kev tshuaj xyuas penetrant, thiab nws qhov zoo cuam tshuam ncaj qha rau qhov rhiab heev ntawm kev tshuaj xyuas. Penetrants yuav tsum muaj cov khoom ntub dej zoo heev los xyuas kom meej cov khoom nkag. Thaum cov penetrant tov nrog cov xim dyes lossis fluorescent dyes, nws muaj txiaj ntsig zoo rau kev txhim kho qhov tsis xws luag. Kev kuaj pom muaj xim tsis zoo siv cov xim dyes ua cov xim xim rau cov neeg nkag mus, thaum kuaj pom qhov tsis haum fluorescent siv cov hmoov fluorescent ua tus neeg sawv cev luminescent rau cov neeg nkag. Txoj kev ntxoov ntxoo tuaj yeem ua haujlwm hauv qhov chaw sab hauv lossis sab nraum zoov. Kev tshuaj xyuas fluorescent penetrant siv fluorescence emission nyob rau hauv ultraviolet lub teeb tawm los ntawm lub teeb dub los qhia qhov tsis xws luag, yog li nws yuav tsum tau ua hauv chav tsaus.
Castings uas xav tau kev soj ntsuam penetrant yuav tsum tau muab ntxuav ua ntej kev soj ntsuam, thiab lawv cov nto roughness yuav tsum tau raws li qhov zoo raws li qhov yuav tsum tau muaj. Cov xeb, nplai thiab xim, roj, noo noo, thiab lwm yam ntawm qhov chaw ntawm qhov casting yuav tsum raug tshem tawm. Tom qab kev soj ntsuam penetrant tiav lawm, qhov saum npoo ntawm cov casting yuav tsum tau muab tshem tawm los ntawm cov penetrant thiab tsim tawm, qhuav thiab, yog tias tsim nyog, tiv thaiv corrosion.
Cov yam ntxwv ntawm Kev Ntsuas Penetrant thiab Nws Scope of Application:
1. Cov txheej txheem thiab cov cuab yeej siv tau yooj yim thiab hloov tau.
2. Cov duab ntawm cov casting tsis txwv, thiab qhov roughness ntawm qhov chaw soj ntsuam yog muaj feem xyuam rau qib zoo ntawm cov casting.
3. Kev ua haujlwm yooj yim, siab rhiab heev, thiab tsis txwv los ntawm cov khoom siv.
4. Tsuas yog qhov tsis xws luag ntawm casting ntawm lossis ze ntawm qhov chaw ntawm qhov casting tuaj yeem kuaj pom.
