Binder ndi Crosslinkers kwa UV Powder zokutira

Binder ndi Crosslinkers kwa UV Zovala za Powder

Njira yabwino kwambiri yopangira zokutira ndikugwiritsa ntchito chomangira chachikulu komanso cholumikizira. The cross¬linker akhoza kulamulira kachulukidwe netiweki kwa ❖ kuyanika, pamene binder amaona katundu ❖ kuyanika monga ma discoloration, kukhazikika panja, makina katundu, etc.

Kuonjezera apo, njira iyi idzatsogolera ku lingaliro lofanana kwambiri mu ntchito zokutira ufa monga gulu lobweretsa mafanizidwe a zokutira za thermosetting kumene crosslinkers monga TGIC ndi hydroxyl amides amagwiritsidwa ntchito. A crosslinker ayenera kupereka katundu mwachindunji kwa ntchito cholinga: molecular kulemera; mkulu magwiridwe antchito; ndi katundu wakuthupi n'zogwirizana ndi ntchito.

Ma crosslinkers a ufa wopaka-UV ayenera mwanjira ina yake kufanana ndi zomwe zatchulidwa pamwambapa zomwe zimagwiritsidwa ntchito popaka ufa wa thermosetting. Tapanga ndikuphunzira kuphatikizika kwa ma acrylic atatu ndi chotengera chimodzi cha allyl, choyenera Zovala za UV powder.
