Nekufambira mberi kwetekinoroji kuri kuramba kuchienderera mberi, lamination isina solvent inogamuchirwa nevakawanda vanogadzira mapakeji anochinjika.
Zvakanakira zve lamination isina solvent zvinokurumidza, zviri nyore, zvisingakuvadzi nharaunda, uye zvisingadhuri zvakanyanya.
Zvakakosha kuti tizive maitiro ekutanga emakemikari panguva yekuyeresa pasina solvent kuti tigadzire huwandu hwakanaka.
Zvikamu zviviriNamatidza isina zvinonyungudutsayakagadzirwa ne polyurethane (PU), PU yakasanganiswa ne isocyanate(-NCO) inonyanya kunzi A component, uye polyol(-OH) inonyanya kunzi B component. Ruzivo rwe reaction ndapota tarisa pazasi;
Mhinduro huru iri pakati peA naB, -NCO ine makemikari anoita ne -OH, panguva imwe chete, nekuda kwekuti mvura inewo boka re -OH rinoshanda, mvura ine makemikari anoita neA component inoburitsa CO2.2,Kabhoni dhayokisaidhi. Uye polyurea.
Mutungamiriri weCO2 zvinogona kukonzera dambudziko remabubbles uye polyurea inogona kukonzera anti-heat seal. Kunze kwekuti kana hunyoro hwakakwira zvakakwana, mvura inoshandisa A component yakawandisa. Mugumisiro wacho ndewekuti glue haigone kupora 100% uye simba rekubatanidza rinodzikira.
Muchidimbu, tinokurudzira kuti;
Kuchengetera namatidza kunofanira kuchengetwa munzvimbo inotonhorera, yakaoma kure nehunyoro
Musha wekushandira unofanira kuchengetedza hunyoro huri pakati pe30% ~ 70%, uye unofanira kushandisa AC kudzora hunyoro.
Pamusoro apa pane maitiro ekutanga emakemikari pakati pezvinonamira zviviri, asi chinonamira chemono-component chichasiyana zvachose, tichazotanga maitiro emakemikari emono component mune ramangwana.
