Polyurethane Dehydration

I-polyurethane (iingubo, izitywini, izincamathelisi)

Ukufuma kwinkqubo ye-PU isabela kunye ne-isocyanate, kungakhathaliseki ukuba i-single-component okanye i-component-component ye-polyurethane yeemveliso, ezivelisa i-amine kunye ne-carbon dioxide, i-amine iyaqhubeka isabela nge-isocyanate, ukwenzela ukuba ukusetyenziswa kwayo ukukhulula i-carbon dioxide gas ngexesha elifanayo, yenza amaqamza kumphezulu wefilimu yepeyinti, ekhokelela ekuwohlokeni okanye nasekusebenzeni kokusilela kwefilimu yepeyinti.

I-2% ~ 5% ye-molecular sieve (powder) kwinkqubo yanele ukususa umswakama oseleyo kwinkqubo ye-PU, kodwa ekugqibeleni kuxhomekeke kumswakama kwinkqubo.

I-anti-corrosive coating

Kwi-epoxy zinc-rich-rich primer, umkhondo wamanzi uya kuvelisa ukusabela okukhulu kunye ne-zinc powder, ukuvelisa i-hydrogen, ukwandisa uxinzelelo kwi-barrel, ukunciphisa ubomi benkonzo ye-primer, kubangele ukuxinana, ukuxhathisa kunye nobunzima. yefilimu yokugquma.I-molecular sieve (powder) njenge-desiccant yokufunxa amanzi, eyi-adsorption yomzimba ngokupheleleyo, iya kuphelisa amanzi kwaye ngaphandle kokuphendula kunye ne-substrate.Ke i-molecular sieve ikhuselekile kwaye ilungele inkqubo yokwaleka okuchasana nomhlwa.

Metal powder ukutyabeka

Iimpendulo ezifanayo zinokwenzeka kwiingubo zomgubo zesinyithi, ezinje ngomgubo we-aluminium.
