Isebenza kanjani i-UV LED powder enamathela? Ukuze uqonde ukuthi lobu buchwepheshe busebenza kanjani, kubalulekile ukuhlukanisa nenqubo yendabuko yokushisa. Ekugqokeni okujwayelekile kwe-powder, ingxenye kufanele ibhake kuhhavini emazingeni okushisa aphezulu (imvamisa azungeze i-400 ° F) imizuzu engama-20 noma ngaphezulu ukwelapha. Ukuphulukiswa kwe-UV LED kushintsha lokhu kuguquka ngokuhlukanisa inqubo ibe yizigaba ezimbili ezihlukene: Lokhu kusebenza kahle kuyisizathu esikhulu sokuthi izimboni zamukele UV LED Curing for Coatings. Kunciphisa kakhulu ukusetshenziswa kwamandla kanye ne-footprint yomzimba yomugqa wokukhiqiza. Izinzuzo eziyinhloko ze-UV LED ye-Powder Uyini umehluko phakathi kwe-Thermal ne-UV Powder Coating? Ukumbozwa kwempuphu yokushisa kuncike ekushiseni kokubili ukuncibilika nokuphulukisa, kuyilapho i-UV powder enamathela isebenzisa ukushisa kuphela ukuncibilika nokukhanya kwe-UV ukwelapha. Ngenkathi ukuphulukiswa kwendabuko okushisayo kuhle kakhulu ezingxenyeni zensimbi ezingamelana nokushisa okuphezulu, kunciphisa lokho ongakugqoka. Ukwelashwa kwe-UV LED kuvula umnyango wezinto ezintsha. Ngezansi ...
