Nzira yekuyedza Adhesive Tape?

Zvinoenderana nebasa rayo, tepi inogona kupatsanurwa kuita: tepi yekupisa yepamusoro, kaviri - mativi tepi, insulating tepi, yakakosha tepi, kumanikidza - sensitive tepi, kufa - kucheka tepi, uye akasiyana mabasa akakodzera kune akasiyana indasitiri zvinodiwa. Tepi inoumbwa nezvikamu zviviri: substrate uye adhesive. Inobatanidza zvinhu zviviri kana kupfuura zvisina kubatanidzwa pamwechete kuburikidza nekubatana. A layer of adhesive yakaputirwa pamusoro payo. Nezve tepi yekunamatira, chinhu chinonyanya kunetseka chinofanira kunge chiri kunaka kwevhisikity yayo. Zvinoenderana nechiitiko chekushandiswa kweadhesive tepi, viscosity yayo inodzorwawo zvakanyanya. Nokudaro, zvinonyanya kukosha kuita mimwe miedzo pamatepi ekunamatira. Iyo inotevera mupepeti inokutora iwe kuti unzwisise zviyero zvekunamira tepi yekuyedzwa kubva pamaonero ekutanga viscosity, inosimudzira viscosity uye peel simba.

1. Peel simba rekuedza

Simba rePeel rinoreva simba rinodiwa kusvuura hupamhi hweyuniti yetepi yekunamira kubva pane yakanamira pamusoro pane imwe kona nekumhanya. Pane nzira mbiri dzekupeura bvunzo, yekutanga ndeye 180 ° kupepeta uye yechipiri ndeye 90 ° kupepeta. Pano ini ndichasuma nzira yekutanga, 180 ° peeling.

Chidimbu chetepi yekunamatira inonamirwa kune simbi isina simbi ndiro, uye simbi isina tsvina ndiro yakagadzikwa pane inogadziriswa yemuchina wekuyedza tensile. Imwe gadziriso yemuchina wekuyedza inosungirira iyo yemahara magumo eanonamira tepi pakona ye180 ° kune stainless simbi ndiro. Tepi yekunamira inodhonzwa nepakati pachiyero chakatarwa, uye simba rekusvuura rinoyerwa nechisimba chinodiwa kuti urambe uchipepeta tepi yekunamira kubva mundiro yesimbi isina tsvina uye ichishandurwa kuita peel simba.

2. 2. Adhesion test

Kunama (stiiness) zvinoreva kuramba kuri kuita pressure-sensitive tepi kana humwe huremu hwaturikwa wakatwasuka pahurefu hwechinhu chakanamirwa. Kana iyo inonamira yakashata, tepi inodonha nyore uye inotadza kuzadzisa chinangwa chekunamatira; kana kunamira kwakanyanyisa, chinhu chakanamatira chinotsemuka nyore kana chaparadzaniswa nechinhu chakanamirwa.

1. (1). Nzira yekuyedza ndeyekukungurutsa bhora resimbi pamusoro penzvimbo inonamira yetepi yekunamira yakaiswa sandara pandiro yakarerekera, uye kuongorora kunamatira kwayo kwekutanga zvichienderana nehukuru hwesimbi bhora saizi inogona kunamatira kune inonamira pamusoro pehurefu hwakatarwa; kana kukungurutsa bhora resimbi rehukuru hwakatarwa pamusoro pegoko rakarerekera uye kuyera nhambwe yarinokungurukira panzvimbo inonamira yetepi yekunamira pandiro yakachinjika kuti iongorore kunamatira kwayo kwekutanga.

2. (2). Mamiriro ekuedzwa: Kunze kwekunge zvataurwa neimwe nzira, tembiricha yemukamuri yekuyedza i23 ° C ± 2 ° C, uye hunyoro hwehukama i50% ± 10%. Usati wagadzirira muenzaniso, matepi ekunamatira anofanirwa kubviswa kubva pamidziyo yavo yekuisa uye kuiswa pasi pemamiriro e5.1 kweanopfuura maawa maviri pasina kupindirana.

3. 3. Yekutanga adhesion test

Initial tack ipfuma yezvinonamira, iyo inogonesa zvinonamira uye zvinonamatira kuti zvigadzire chisungo chine simba rinoyerwa nekukurumidza pasi pekumanikidzwa kwakaderera mushure mekusangana. Hunhu hwekutanga tack hunokanganisa zvakananga kunaka kwezvinonamira uye zvine zvakakosha zvakanyanya kukosha kune mamwe maapplication. Muyero unowanzo shandiswa pakuyedza yekutanga tack ndeye PT-6030 tepi yekutanga tack tester, inoda kuti sampu yetepi itevedzerwe neinonamira yakatarisa kumusoro pandiro yekuyedza ine inclination ye30 °. Mabhora esimbi anotorwa kubva kunhamba hombe uye anotenderwa kukunguruka akasununguka pamuenzaniso mukutevedzana. Nhamba yebhora inonamatira kumuenzaniso kweanopfuura 5 seconds inonyorwa seyokutanga tack kukosha kwe tepi.
