E nwekwara ike ghara ebibi na metal, ma wetara si aesthetic echiche, na onu - yellowing nke agba.

Ugbu a, ndị chemical ụlọ ọrụ na-arụpụta ọtụtụ iche iche nke okpomọkụ na-eguzogide ink e maka egosipụta metal ebupụta, dabere na okpomọkụ gburugburu ebe obibi nke ga-ejikwara site otu ma ọ bụ ọzọ ngwaahịa.

The ọkara nke metal n'elu bụ kpụ ọkụ n'ọnụ ka okpomọkụ nke 80 ° C, enye ohere iji ihe ọ bụla nke ágbá.

The okpomọkụ na-eguzogide agba maka metal, mere dabeere na alkyd na acrylic resins, eji maka dyeing owuwu gụrụ okpomọkụ ruo 100 ° C, o nwere a pụrụ iche okpomọkụ na-eguzogide ha nwekwara, nke gbochie n'elu yellowing mgbe ewe iwe. A, nke a na umu-eji maka staining nke ezinụlọ radiators na-ekpo ọkụ mmiri na usoro.

N'ihi na staining nke dị iche iche na usoro na bughi ọcha na-arụ ọrụ na okpomọkụ ruo 120 ° C iji okpomọkụ na-eguzogide agba maka metal, mere iji ihe epoxy primer na na mgbakwunye na nke zinc na zinc-phosphate mmiri. Epoxy Enamel nwekwara ike ga-eji na elu okpomọkụ - ruo 200 Celsius C.

Mgbe okpomọkụ ọchịchị ruo 400 ° C na-atụ aro iji otu-akụrụngwa mkpuchi, isi nwere ethyl silicate na epoksiefirnye resin. Mgbe a na okpomọkụ, ot pigments oké ike ọgwụgwụ na-adị instantaneously, otú a okpomọkụ na-eguzogide agba nwere a metal ya mejupụtara a metal ntụ ntụ. Nke a mgbanwe nwere ike etinyere ibuotikọ ke otu oyi akwa.

Na-arụ ọrụ ọnọdụ, ngwaahịa ma ọ bụ Ọdịdị na a okpomọkụ nso ruo 650ºC, ndị ọkachamara nwere ike ikwu na iji otu akụrụngwa mkpuchi, isi nwere silicone resin. Na nke a, na okpomọkụ na-eguzogide agba na-etinyere na metal n'elu a nnọọ mkpa oyi akwa na-enwe a uru nke si 30 ka 100 microns.

The okpomọkụ ọchịchị na ngafe nke 650ºC-agụnye iji dị ka a agba? Ihe mkpuchi arụpụtara na ndabere nke okpomọkụ na-eguzogide iko na mejupụtara ihe.
