4. Dacromet Coating - Babban Kariyar Lalacewa

Dacromet fasaha ce ta tutiya-flake mai rufi (wanda aka samo asali ta Metal Coatings International). Ya ƙunshi flakes na tutiya da aluminium da aka dakatar a cikin ɗaure na inorganic, ana amfani da su ta hanyar dip-spin ko hanyoyin fesa kuma an warke a kusan 300-340 ° C. Sakamakon bakin ciki, mai yawa, fim ɗin launin toka na azurfa yana ba da kariyar lalata kayan aiki da yawa ba tare da haɗarin haɓakar hydrogen ba - fa'ida mai mahimmanci ga masu ƙarfi masu ƙarfi kamar Grade 10.9 da 12.9.

5. Haɗe-haɗe Abũbuwan amfãni & Na yau da kullum Aikace-aikace

Lokacin da ƙarfin Grade 10.9, hexagonal head geometry, da Dacromet shafi aka haɗu, sakamakon faɗuwar yana ba da ingantaccen ma'auni na aikin injiniya, dacewa da taro, da dorewa na dogon lokaci a cikin mahalli masu lalata.

Fa'idodin Farko

1.High clamp load capability - yana ba da damar ƙirar haɗin gwiwa mai sauƙi da aminci mafi girma a ƙarƙashin rawar jiki da nauyin nauyi.

2.Superior lalata juriya - gishiri-fesa yi nisa ya wuce na al'ada tutiya plating yayin da tsare thread daidaito.

3.Hydrogen-embrittlement free - mahimmancin yanayin aminci don ƙarfin ƙarfe mai ƙarfi.

4.Controlled gogayya - lubricated Dacromet bambance-bambancen karatu samar da tsinkaya karfin juyi-tension dangantaka, inganta taro daidaito.

5.Thermal kwanciyar hankali - ya kasance mai karewa a yanayin zafi mai zafi da aka samu a cikin ɗakunan injin da kayan aikin masana'antu.

Filayen Aikace-aikace na yau da kullun

Mota: chassis, dakatarwa, hawan injin, abubuwan haɗin wutar lantarki
Ƙarfin iska: hasumiya flanges, nacelle Tsarin, tushe anchors
Babban gini & ababen more rayuwa: gadoji na karfe, hasumiya mai watsawa, titin jirgin kasa
Injin noma da gine-gine suna aiki a waje
Kayan aikin ruwa da na teku (tare da zaɓin matakin da ya dace)

6. Kammalawa

Mataki na 10.9 Dacromet hexagon head bolts yana ba da ingantaccen haɗin gwiwa mai ƙarfi mai ƙarfi, ƙirar shigarwa mai amfani, da kariya ta lalata na dogon lokaci. Ta hanyar saduwa da ƙayyadaddun buƙatun inji na ISO 898-1 Class 10.9, daidai da ƙa'idodin ƙima kamar ISO 4014, da kuma amfani da murfin tutiya-flake-free na hydrogen-embrittlement, waɗannan masu ɗaure suna ba injiniyoyin ingantacciyar mafita don mahimman hanyoyin haɗin gwiwa da aka fallasa ga duka matsalolin injiniya da mahalli.
