Kuongorora Zvishandiso uye Zvimiro zveDziviriro Mafirimu

Iyo aluminium inodzivirira firimu ndiyo yakasarudzika fomula ye polyethylene (PE) firimu se substrate, polyacrylic acid (ester) resin sechinhu chekutanga chekumanikidza-sensitive adhesive, yakasanganiswa neakati wandei anonamira ekuwedzera kuburikidza nekupfeka, kucheka, kurongedza, uye mamwe maitiro. firimu rekudzivirira rakapfava, rine simba rakanaka rekunamira, nyore kunamira, nyore kusvuura. Pressure-sensitive adhesive stability yakanaka uye haizokanganisa nzvimbo yechigadzirwa ichinamirwa.

Chiyero chekushandisa: Inonyanya kushandiswa kune ese marudzi epurasitiki, yemapuranga ndiro (shiti) kudzivirira pamusoro, sePVC, PET, PC, PMMA-mbiri-mavara ndiro, foam board UV bhodhi, girazi, uye mamwe maplate nzvimbo mukutakura, kuchengetedza. , uye kugadzirisa, kuisa maitiro pasina kukuvara.

Chimiro uye zvinhu zvemukati zvekudzivirira firimu

Iyo inodzivirira firimu inowanzoita polyacrylate inodzivirira firimu, polyacrylate inodzivirira firimu reiyo yekutanga chimiro kubva kumusoro kusvika pasi: yekuzviparadzanisa layer, kudhinda layer, firimu, adhesive layer.

(1, yekuzviparadzanisa layer; 2, kudhinda layer; 3, firimu; 4, adhesive layer)

1. Firimu

Sezvishandiso, firimu rinowanzo gadzirwa repasi-density polyethylene (PE) uye polyvinyl chloride (PVC). Extrusion molding, jekiseni kuumba, uye kuputika kuumba kunogona kuwanikwa. Sezvo polyethylene yakachipa uye yakanyanya kushamwaridzana kwezvakatipoteredza, 90% yefirimu inogadzirwa nepolyethylene, ine kuvhuvhuta maitiro seyakanyanya kutariswa. Kune akawanda marudzi e polyethylene ane siyana ekunyunguduka uye densities.

2. Colloid

Maitiro ecolloid anosarudza kiyi kune yakanaka uye yakaipa yefirimu inodzivirira. Iyo inodzivirira firimu inoshandiswa mukumanikidza-inonamatira adhesive ine marudzi maviri: solvent-based polyacrylate adhesive uye mvura-soluble polyacrylate adhesive; vane maitiro akasiyana.

Solvent-based polyacrylate adhesive

Solvent-based polyacrylate adhesive is an organic solvent sepakati yekunyungudutsa iyo acrylic monomer; iyo colloid inonyatso kujeka, iyo yekutanga viscosity yakaderera, uye inopesana zvakanyanya nekuchembera kusvika kumakore gumi kana yaiswa kune ultraviolet chiedza; iyo colloid ichaporawo zvishoma nezvishoma. Mushure mekunge iyo firimu yaitwa corona-treated, polyacrylate adhesive inogona kuvharirwa zvakananga pasina primer. Polyacrylate adhesive yakanyanya kuoma uye ine hurombo husina mvura, saka inodzivirira firimu adhesion inotamba zvishoma nezvishoma; kunyangwe mushure mekumanikidzwa, iyo gel uye nepamusoro kuti itumirwe haigone kubatwa zvizere. Yakaiswa 30 ~ 60 mazuva gare gare, ichange yakanyatsobatana nechepamusoro kuti itumirwe kuitira kuti iwane kunamatira kwekupedzisira, uye kunamatira kwekupedzisira kunowanzova kukuru kudarika kunamatira kwekunamatira kwe 2 ~ 3 nguva, kunamatira kwe. iyo inodzivirira firimu, kana yakakodzera bhodhi fekitari yekucheka, iyo yekupedzisira-mushandisi kubvarura iyo firimu kana iripo Inogona kunge yakanyanya kuoma kana kunyange haigoni kubvarurwa.

Mvura-soluble polyacrylate adhesive

Mvura-inonyungudika polyacrylate adhesive inoshandisa mvura sesvikiro kunyungudutsa acrylic monomer. Iyo inewo hunhu hwe solvent-based polyacrylate adhesive, asi iyo colloid inofanirwa kudzivirirwa kuderedza kusangana nemhute yemvura uye kudzivirira yakasara glue. Nyika dzichiri kusimukira dzinowanzoshandisa colloid kugadzira firimu rekudzivirira nekuti mvura inonyungudika polyacrylate adhesive ine hushamwari kwezvakatipoteredza uye haidi solvent recovery device.

3. Hunhu hwecolloid

Adhesion

Inoreva nguva iyo firimu rinodzivirira kubva pamusoro rakanamirwa kune simba rinodiwa kusvuura. Simba rekunamatira rine hukama nechinhu chinofanira kuiswa, kudzvanywa, nguva yekushandisa, kona, uye tembiricha paunenge uchibvisa firimu. Zvinoenderana neCoating Online, kazhinji, nekukwira kwenguva nekumanikidza, simba rekunamatira rinosimukawo; iyo inodzivirira firimu inonamatira inogona kukwira zvakanyanya kuti ive nechokwadi chekuti hapana yakasara yekunamatira kana kubvarura firimu.Kazhinji, kunamatira kunoyerwa kuburikidza ne180-degree peeling test.

Kubatana

Inoreva kusimba kwecolloid mukati, sefirimu yekudzivirira yekubatana kwecolloid inofanira kuva yakakwirira kwazvo; kana zvisina kudaro, mukubvarura iyo inodzivirira firimu, iyo colloid ichatsemuka mukati, zvichiita kuti irambe yakanamatira. Kuyerwa kwekubatana: Iyo firimu inodzivirira ichanamirwa kune simbi isina tsvina, uye huremu chaihwo hunenge hwakarembera pane inodzivirira firimu kuyera kuti inguva yakawanda sei inodiwa kubvisa iyo inodzivirira firimu nehuremu. Kana simba rekunamatira rakakura kudarika simba rakabatana, bvarura iyo inodzivirira firimu, uye mamorekuru anonamatira akabatanidzwa pakati pechisungo achatyoka, zvichiita kuti pave nekunamatira.

Adhesion

Izvi zvinoreva simba rekubatanidza pakati pekunamatira uye firimu. Kana simba rekunamatira rakakura kudarika simba rekubatana, kana firimu yekudzivirira ikabviswa, chisungo pakati pemamolekemu anonamatira uye firimu ichaputsika, zvichiita kuti igare yakanamatira.

UV Kupokana

Polyacrylate adhesive is UV resistant, transparent polyacrylate adhesive firimu inodzivirira ine UV stabilizer; inoshingirira kuUV kwenguva inosvika 3 ~ 6 mwedzi. Kushandiswa kwakajairwa kwemidziyo yekuenzanisa yemamiriro ekunze kuyedza simba reUV remufirimu rinodzivirira nekugadzirisa tembiricha yemwaranzi, uye condensation kutevedzera shanduko yemamiriro ekunze maawa matatu ega ega ehunyoro hwepamusoro uye maawa manomwe eradio ultraviolet kutenderera kwemaawa makumi mashanu kutenderera kwekuyedza. zvakaenzana neinokwana mwedzi mumwe chete yekuiswa panze.
