Zvese Zvaunoda Kuziva Nezve Dzvinyiriro-Sensitive Adhesives mune Dziviriro Mafirimu

Iyo inonamira-inomira-inomira yakashandiswa mukatiMafirimu Anodzivirira inogona kuiswa muzvikamu zvina: natural rubber, synthetic rubber, water-soluble acrylic, uye solvent-based acrylic. Chinokosha kune chakanaka uye chakaipa chefirimu yekudzivirira inotarirwa nemaitiro ekunamatira, ane maitiro akasiyana.

1. Rabha yakasikwa ine kubatana kwepamusoro, saka kazhinji haibudisi rasara guruu. Iyo resin uye zvinowedzera zvinogadzirisa viscosity. Zvisinei, nzira yekuputira inonyanya kuoma; zvakakosha kuisa primer pafirimu kutanga kuvandudza simba repamusoro refirimu risati ravharwa nerabha rinogona kuputirwa paPE firimu.Munzvimbo dzemukati, rabha rechisikigo rinogona kuramba risina kuchinjika kweanosvika makore maviri, asi rinodzikisira uye zera mukati memwedzi 3-12 kana rakafumurwa nechiedza cheUV. Iyo UV-inodzivirira dema uye chena firimu rinodzivirira rinowanzo kuumbwa nezvikamu zvitatu: iyo yemukati-kati, dema, inogona kunyatsotora ultraviolet mwaranzi; chikamu chepakati, chichena, chinogona kuratidza chiedza kuitira kuti firimu rinodzivirira rikwanise kuderedza simba rekutora, kuderedza kuchembera kwegel, jira repamusoro: chena: inogona kuvhara zvachose dema remukati, ruvara ruchena runogona kudhindwa. zvakanyanyisa kunaka. Saka kunyangwe mushure memwedzi gumi nemiviri yekubuda kunze, rabha haizochembera. Bvisa kunetseka kwevagadziri. Typical natural rabha ine chiedza yeyero ruvara. Iko kusungirirwa kwekutanga kwerabha yechisikigo kwakanaka, uye zvinonetsa kusunungura guruu uye kunamatira zvakasangana.

2. Synthetic rubber inogona kupa yakakwira viscosity uye kuramba mamiriro ekunze

Synthetic rabha inogona kupa yakakwira viscosity uye kuramba kwemamiriro ekunze, asi kwenguva yakareba, glue inorapwa, uye yekutanga viscosity inodzikiswa, saka iyo yekugadzira rabha inowanzowedzerwa kune yakasikwa rabha.

3. Mvura-soluble acrylic imvura sechinhu chinopisa acrylic monomer

Sezvo zvakanyanya kushamwaridzana kwezvakatipoteredza uye zvisingade zvigadziriso zvekugadzirisa zvinonyungudutsa, nyika dzichiri kusimukira dzinowanzoshandisa colloid inonyungudika nemvura kugadzira firimu rinodzivirira. Mvura-soluble acrylic ine maitiro e-solvent-based protective film. Iyo inonamira pamusoro pemvura inonyungudika inodzivirira firimu inofanirwa kudzivirira uye kuderedza kusangana nemhute yemvura kudzivirira yakasara yakanamatira. Iyo inonyungudika nemvura inonamira inodzivirira firimu inoratidzirwa nekunyanya nyore uye nekukurumidza kubvarura. Mvura-soluble acrylic inodzivirira firimu muUnited States neAsia ine zvakawanda.

4. solvent-based acrylic ndiko kushandisa organic solvents sepakati kunyungudutsa acrylic monomer

Acrylic adhesive iri pachena uye inopesana nekuchembera kusvika kumakore gumi. Iyo inonamira zvakare inorapa zvishoma nezvishoma kana yaiswa kune UV mwenje. Kuenzaniswa nerabha, acrylic adhesives ane yakaderera yekutanga tack. Mushure mekunge iyo firimu yave yakarapwa korona, iyo acrylic adhesive inogona kuiswa zvakananga pasina primer. Mafirimu eAcrylic anoita jittery, ruzha rwakakasharara kana uchisununguka, ukuwo mafirimu erabha anofenda neruzha rwakapfava. Kuenzaniswa neyakanamatira acrylic, rabha yakatsetseka uye ine mvura yakanaka. Mushure mekudzvinyirirwa, inokurumidza kuita kusangana kwakazara nepamusoro kuti ishandiswe, saka iyo inonyanya kukosha yerubha-mhando yekudzivirira firimu ndeyokuti inonamira inokurumidza kuiswa, uye yekupedzisira adhesion inosvika nekukurumidza mushure mekumanikidzwa ne roller. . Yakakodzera kucheka nebhodhi fekitori uye yakanakira kwazvo kuti mushandisi wekupedzisira kubvarura iyo firimu. Kune nzvimbo dzakakasharara, mushure mekumanikidzwa, zvakanakira kuyerera kwakanaka kwemamorekuru erabha zviri pachena; vanogona kukurumidza kudzvinyirirwa mukuora mwoyo kwakasiyana-siyana uye kuve nekusangana kwakazara nechepamusoro.

Iyo acrylic rubber yakaoma uye ine kusafamba zvakanaka, saka kunamatira kweiyo acrylic inodzivirira firimu inotamba zvishoma nezvishoma; kunyangwe mushure mekumanikidzwa, iyo gel uye nepamusoro kuti itumirwe haigone kubatwa zvizere. Yakaiswa 30-60 mazuva gare gare, ichava yakazara kusangana nechepamusoro kuti itumirwe kuti ibudirire kusungirirwa kwekupedzisira, uye kusungirirwa kwekupedzisira kunowanzova kukuru kudarika kunamatira kwekunamatira kwe viscosity ye2-3 nguva.
