I-Polyurethane Dehydration

I-polyurethane (ama-coatings, ama-sealants, ama-adhesives)

Umswakama ohlelweni lwe-PU usabela nge-isocyanate, kungakhathaliseki ukuthi ku-single-component noma emikhiqizweni emibili ye-polyurethane, ekhiqiza i-amine ne-carbon dioxide, i-amine iyaqhubeka nokusabela nge-isocyanate, ukuze ukusetshenziswa kwayo ukukhulula i-carbon dioxide gas ngesikhathi esifanayo, yenza ama-bubbles ebusweni befilimu kapende, okuholela ekuwohlokeni noma ngisho nokusebenza kokuhluleka kwefilimu kapende.

I-2% ~ 5% yesisefo samangqamuzana (impushana) ohlelweni yanele ukususa umswakama osele ohlelweni lwe-PU, kodwa ekugcineni kuya ngomswakama ohlelweni.

I-anti-corrosive coating

Ku-primer ecebile ye-zinc epoxy, inani elincane lamanzi lizoveza ukusabela okuhle nge-zinc powder, likhiqize i-hydrogen, likhulise ingcindezi emgqonyeni, lifinyeze impilo yesevisi ye-primer, okuholela ekuqineni, ukumelana nokugqoka kanye nobunzima. yefilimu yokugqoka.Isisefo samangqamuzana (impuphu) njenge-desiccant yokumunca amanzi, okuyi-adsorption ebonakalayo ngokuphelele, izowaqeda amanzi futhi ngaphandle kokusabela nge-substrate.Ngakho-ke isisefo samangqamuzana siphephile futhi silungele isistimu yokuhlanganisa evimbela ukubola.

I-Metal powder enamathela

Ukusabela okufanayo kungenzeka ezimbotsheni zempushana zensimbi, njengasezimbozweni eziyimpushana ze-aluminium.
