Dacromet Flange Bolts

Anti-lalata Flange Fasteners tare da Zinc-Aluminum Flake Coating

Dacromet flange bolts sun haɗu da ƙirar flange mai rarraba kayan aiki tare da murfin flake na Dacromet zinc-aluminum. Flange mai haɗaka ya maye gurbin mai wanki daban, yayin da murfin Dacromet yana ba da sa'o'i 500-1,200 na juriya na feshin gishiri ba tare da haɓakar hydrogen ba - manufa don kera, gini, da aikace-aikacen ruwa.

Sashe na 2 - Dacromet Coating

Dacromet shine tushen ruwa, rufin da ba na lantarki ba na tutiya mai rufi da flakes na aluminum wanda aka haɗa ta mahaɗan chromium. Ana amfani da shi ta hanyar hawan keke-spin-cure a 280-300 ° C, yana ba da kariya ta lalata mai Layer uku ba tare da haɓakar hydrogen ba.

Tsarin Kariya

Kariyar hadaya: Filayen Zinc suna lalata da kyau don kare karfe, koda lokacin da aka taso.
Shamaki na jiki: Filaye masu haɗe-haɗe suna toshe danshi, oxygen, da ions masu lalata.
Ƙimar kimiyya: Maharan Chromium suna jinkirin narkar da zinc da kuma warkar da micro-scratches.

Mabuɗin Amfani

Babu hydrogen embrittlement: Ba-electrolytic tsari - lafiya ga Grade 8.8-10.9 high-ƙarfi kusoshi.
Mafi girman juriya na lalata: 500-1,200 sa'o'i na gishiri gishiri (ISO 9227), 5-10x mafi kyau fiye da plating na zinc.
