Muchinyorwa chakapfuura, takataura maitiro ekutonga kupera kwegonhi Hardware kuburikidza nepamusoro.Panguva ino tichataura pamusoro pechipi bvunzo chinoda kuitwa pakurapa kwepamusoro.Kupedzwa kwemidziyo yemusuwo haingokanganisa kunaka uye kunzwa kwegonhi Hardware, asi zvakare ine chekuita nekushongedzwa kweoxidation yegonhi Hardware, kunyanya munzvimbo dzemahombekombe kana nzvimbo dzine hunyoro hwemamiriro ekunze.Kana kupedzisa kwegonhi hardware kusina kuitwa zvakanaka, zvichava nyore kuisa oxidize uye kukonzera mavara machena pamusoro.
Ticharamba tichitora mubato wegonhi semuenzaniso munguva ino.Kupera kwemubato wegonhi kunonyanya kutariswa kuti ndeupi rudzi rwekurapa kwepamusoro mubato wegonhi unogadzirwa.Nekudaro, kune kumwe kuyedzwa kunodiwa kune ese epamusoro kurapwa.
1. Salt Spray Test.Nzira yakajairika yekuyedza kupfapfaidza munyu ndeyekuisa chigadzirwa mumudziyo wekupfapfaidza munyu, uye kuongorora kusaora kwechigadzirwa nekugadzira nharaunda inofananidzwa yekupfapfaidza munyu.Mhedzisiro yebvunzo inowanzova chiratidzo chakakosha chekusimba kwepamusoro kwechigadzirwa.Muyero wekuyedza unowanzo kupatsanurwa kuita 48h, 72h, 96h, etc. Iyo yakareba nguva, zviri nani kuramba kwecorrosion kwechigadzirwa.
2. Doro abrasion test.Kuputira huremu hwe500g ne gauze, inyika muine 95% yemishonga yedoro solution, uye woipukuta nekudzoka shure ka50 nekumhanya kwe 2 kumashure nekudzoka / sec mukati me 60mm kureba kwechigadzirwa.Kana iyo chigadzirwa chepamusoro chisati chapera sekukodzera, bvunzo iri kunyanya kuona kupikisa kwedoro kwechigadzirwa.
Kana iyo hardware yemusuwo ikapfuura bvunzo mbiri dziri pamusoro, zvinotoreva kuti pamusoro pechigadzirwa ichi chine hupenyu hurefu hwebasa, uye hazvisi nyore kuve nemavara machena uye ngura.Chimwezve chinhu chekutaura pano, kana kupera kwegonhi hardware iri pendi yekupfapfaidza, imwezve bvunzo inodiwa:cross-cut test.
Muchinjikwa-cheka bvunzondeye kushandisa cross-cut tester kudhirowa 10 * 10 1mm * 1mm magedhi madiki pamusoro pechigadzirwa, wobva washandisa 3M 600 tepi kunamira gidhi diki rakaedzwa, nekukasira kubvisa tepi, uye kuita bvunzo mbiri panguva imwe chete. chinzvimbo.Pendi peeling ratio inogona kukamurwa kuita 5B, 4B, 3B, 2B, 1B uye 0B.Iyo yakakura nhamba, iyo yakasimba yekunamatira kwepende, uye zvishoma zvingangoita kuti chigadzirwa chibude.
Nhasi kugovana kunopera pano, kana iwe uchida kuziva zvakawanda nezvemusuwo Hardware, unogamuchirwa kushanyira webhusaiti yedu.
