Maitiro Ekuongorora Coating Adhesion-Tape Test
Kusvika kure bvunzo yakapararira yekuongorora kupfeka kunamatira ndiyo bvunzo yetepi-uye-peel, yakashandiswa kubvira kuma1930. Mushanduro yaro yakapfava chidimbu chetepi yekunamira inotsikirirwa pairi pendi firimu uye kuramba uye dhigirii rekubvisa firimu rinocherechedzwa kana tepi yadhonzwa. Sezvo firimu rakasimba rine adhesion inoyemurika risingabviswe zvachose, kuomarara kwebvunzo kunowanzo kuwedzeredzwa nekucheka mufirimu mufananidzo X kana muchinjikwa wakachonywa patani, usati waisa nekubvisa tepi. Adhesion inozoyerwa nekuenzanisa firimu rakabviswa pachiyero chakagadzwa chechiyero. Kana iyo firimu yakasimba yakasvunurwa zvakachena ne tepi, kana kuti ikabatana nekucheka mukati mayo pasina kushandisa tepi, ipapo kunamatira kunotaridzirwa sehurombo kana hurombo zvikuru, kuongororwa kwakanyatsojeka kwemafirimu akadaro asiri mukati mekukwanisa kweizvi. test.
Shanduro yemazuva ano inoshandiswa nevakawanda yakatanga kubudiswa muna 1974; nzira mbiri dzekuyedza dzakafukidzwa mune iyi chiyero. Nzira mbiri dzekuedza dzinoshandiswa kuona kana kunamatira kwejasi kune substrate kuri padanho rakakwana; zvisinei ivo havasiyanisi pakati pemazinga epamusoro ekunamatira ayo anodiwa nzira dzakaoma kunzwisisa dzekuyera.Mitemo mikuru yetepi bvunzo ndeyekunzwa kwayo kuderera, kushanda chete kune machira ezvisungo zvishoma, uye kusatsunga kwekunamatira kune substrate. uko kukundikana kunoitika mukati mejasi rimwe chete, senge pakuyedza maprimers ega, kana mukati kana pakati pejasi mune multicoat masisitimu. Kune ma multicoat masisitimu uko kukundikana kwekunamatira kunogona kuitika pakati kana mukati mejasi, kunamatira kweiyo coating system kune substrate haina kutsanangurwa.
Kudzokororwa mukati meimwe rating unit is generally akacherechedzwa zvekunamira pasimbi kune ese ari maviri nzira, nekuberekana kweimwe kusvika kumayuniti maviri. Iyo tepi bvunzo inonakidzwa nemukurumbira wakapararira uye inoonekwa se "yakapusa" pamwe chete nemutengo wakaderera. Yakaiswa kune simbi, ine mari kuita, inokweretesa pachayo kune basa saiti application, uye zvakanyanya kukosha, mushure memakumi emakore ekushandiswa, vanhu vanonzwa vakasununguka nazvo.
Kana tepi yakanamatira inogadziriswa inoshandiswa kune yakavharwa yakaoma substrate pamusoro uye yobva yabviswa, nzira yekubvisa yakatsanangurwa maererano ne "peel phenomenon," sezvinoratidzwa muFig. X1.1.
Kubvisa kunotanga pa "mazino" kumucheto (kurudyi) uye kunoenderera mberi neadhesive / interface kana coating / substrate interface, zvichienderana nekusimba kwechisungo. Zvinofungidzirwa kuti kubviswa kwekuvhara kunoitika kana simba rekumanikidza rinogadzirwa pamwe neiyo yekupedzisira interface, inova basa reiyo rheological maitiro einotsigira uye adhesive layer zvinhu, yakakura kupfuura iyo bond simba pane coating-substrate interface (kana cohesive simba re). the coating).Chaizvoizvo, zvisinei, simba iri rinogoverwa pamusoro pechinhambwe (OA) muFig. X1.1, iyo inoenderana zvakananga nemidziyo inotsanangurwa, isina kuisirwa pane imwe nzvimbo (O) muFig.
Sezviri muchiitiko chedzidziso-kunyangwe simba rekusimba rakakura pamavambo kune ese ari maviri. Simba rakakosha rekumanikidza rinomuka kubva pamhinduro ye tepi inotsigira zvinhu kusvika pakutambanudzwa. Saka ese ari maviri anomanikidza uye anomanikidza masimba anobatanidzwa mukunamatira tepi bvunzo.
Kunyatsoongorora kwe tepi bvunzo maererano nemhando ye tepi yakashandiswa uye zvimwe zvikamu zvemaitiro pachayo zvinoratidza zvinomwe.ral zvinhu, imwe neimwe kana chero musanganiswa wayo unogona kukanganisa zvakanyanya mhedzisiro yebvunzo sezvakakurukurwa (6).
