GEOMET® (Jumete) Mai Rufaffen Hexagonal Bolts-Gabatarwa na Fasaha 

1. Gabatarwa zuwa GEOMET® (久美特) Rufi

GEOMET® (wanda aka fi sani da Sinanci a matsayin 久美特 ko Jumete) ba shi da chromium, rufin flake na tutiya-aluminum mai tushen ruwa wanda NOF Metal Coatings Group ya haɓaka a matsayin magajin muhalli ga tsarin DACROMET® na gargajiya. Yana ba da kyakkyawan kariya ga lalata kayan haɗin ƙarfe, musamman maƙallan hexagonal, yayin da cikakken cika ka'idodin muhalli na zamani kamar RoHS, REACH, ELV (2000/53/EC), da ISO 10683.

Rufin ya ƙunshi passivated zinc da aluminum flakes daure da wani inorganic matrix. Ana amfani da su ta hanyar dip-spin ko hanyoyin fesa kuma ana warkewa a ƙananan yanayin zafi, GEOMET® yana samar da fim ɗin siraren ƙarfe na azurfa-launin toka (yawanci 6-12 μm) wanda baya shafar girman zaren ko dacewa. Saboda tsarin ba shi da wutar lantarki, yana kawar da haɗarin haɓakar hydrogen gaba ɗaya - muhimmiyar fa'ida ga ƙwanƙwasa mai ƙarfi (darussan dukiya 8.8, 10.9 da 12.9).

Lokacin ƙayyade GEOMET® kusoshi hexagonal, la'akari da waɗannan:

1. Ajin lalata da ake buƙata → zaɓi GEOMET 321 (misali), 500 (mai sarrafa gogayya) ko 720 (mafi girman kariya).
2. Ƙarfin injina → zaɓi nau'in dukiya 8.8, 10.9 ko 12.9 bisa ga abubuwan nauyi da aminci.
3. Nau'in zaren → ɓangaren ɓangaren zaren (ISO 4014) don haɗin kai mai mahimmanci; Cikakken zaren (ISO 4017) don matsakaicin haɗin gwiwa.
4. Ƙimar juzu'i → ƙididdige PLUS® topcoat idan dangantakar tashin hankali mai sarrafawa yana da mahimmanci.
5. Bukatun muhalli & tsari → GEOMET® ya gamsar da RoHS, REACH da ELV ba tare da ƙarin keɓewa ba.

4.3 Bayanan Tabbacin Inganci

Mashahurai masu amfani da shafi suna kula da takaddun shaida (ISO 9001) kuma galibi suna riƙe amincewar OEM (Toyota, GM, da sauransu). Ya kamata a tabbatar da kauri mai rufi, manne (gwajin tef), aikin fesa gishiri da ƙimar juzu'i bisa ga ISO 10683 da zanen abokin ciniki. Siffar gani iri ɗaya ce ta azurfa-launin toka; bambance-bambancen baƙar fata (GEOBLACK®) kuma ana samun su lokacin da kayan ado ko ganowa ke buƙatar sa.

5. Kammalawa

GEOMET® (久美特) mai rufi hexagonal bolts sun haɗu da ingantattun amincin injiniyoyi na madaidaicin hex-head fasteners tare da na zamani, chromium-free zinc-aluminum flake shafi wanda ke ba da kariya ta musamman na lalata, yarda da muhalli da 'yanci daga haɓakar hydrogen. Ko ana amfani da shi a cikin chassis na mota, aikin ƙarfe na tsari ko injunan masana'antu, waɗannan masu ɗaure suna ba da ingantacciyar hanyar fasaha da ingantaccen bayani don aikace-aikace masu buƙata.

Don takamaiman shawarwarin aiki, ƙayyadaddun shafi ko bayanan kadarorin inji, tuntuɓi daidaitattun ka'idodin ISO (4014, 4017, 898-1, 10683) da takaddun bayanan fasaha da NOF Metal Coatings Group ya bayar ko masu neman izini.
