Binder le Crosslinkers bakeng sa UV Powder Coatings

Binder le Crosslinkers bakeng sa UV Liaparo tsa Powder

Mokhoa o loketseng ka ho fetisisa bakeng sa ho etsoa ha litlolo ke tšebeliso ea sekontiri se seholo le crosslinker. Cross¬linker e ka laola sekhahla sa marang-rang bakeng sa ho roala, ha sekontiri se etsa qeto ea thepa ea ho roala joalo ka discoloration, botsitso ba kantle, thepa ea mochini, joalo-joalo.

Ho feta moo, mokhoa ona o tla lebisa ho maikutlo a homogenous ho feta likopo tsa ho roala phofo e le sehlopha se tlisang papiso ea liphahlo tsa thermosetting moo ho sebelisoang li-crosslink tse kang TGIC le hydroxyl amides. Crosslinker e lokela ho hlahisa thepa e tobileng haholo bakeng sa kopo e reretsoeng: boima ba molek'hule; tshebetso e phahameng; le thepa ya mmele e tsamaellanang le tshebediso.

Li-Crosslinkers bakeng sa phofo ea ho roala UV e tlameha ho lumellana ka tsela e itseng le thepa ea li-crosslinkers tse boletsoeng ka holimo tse sebelisetsoang ho roala phofo ea thermosetting. Re hlophisitse le ho ithuta ts'ebetso ea crosslinking ea li-acrylic tse tharo le derivative e le 'ngoe ea allyl, e loketseng Liaparo tsa phofo tsa UV.
