Polyurethane dehydration

I-Polyurethane (ukumbona, ama-sealants, anamathela)

Ukuswakama kohlelo lwe-PU kuphendula nge-isocyanate, akunandaba nengxenye eyodwa noma ingxenye ye-polyurethane emibili, ekhiqiza i-Amine ne-Carbon DIOXIDE, ukuze kusetshenziswe ama-ashone, kuholele ekuwohlokeni noma ekusebenzeni kokwehluleka kwefilimu.

2% ~ 5% wesihluthuli se-molecular (i-powder) ohlelweni kwanele ukususa umswakama osalayo ohlelweni lwe-pu, kepha ekugcineni kuye ngokuya ngomswakama ohlelweni.

I-coating elwa ne-corlosive

Ku-epoxy zinc-rich primer, inani lamanzi elilandelwayo lizokhiqiza ukusabela okuhle nge-zinc powder, likhiqize i-hydrogen, linciphise ingcindezi emgqonyeni, okuholela ekuqiniseni, ukugqoka ukumelana nobulukhuni befilimu yokuhlanganisa. Isihlungo se-molecular (i-powder) njenge-desiccant yokuthola amanzi, okuyinto ebonakalayo ngokuphelele e-adsorption, izosusa amanzi futhi ngaphandle kwanoma yimuphi usabela nge-substrate. Ngakho-ke isihlungo se-molecular siphephile futhi silungele uhlelo lokuhlanganisa lokuhlanganisa lokuhlanganisa.

I-metal powder coating

Ukuphendula okufanayo kungenzeka embonweni we-metal powder, njengokumbona kwe-aluminium powder.
