Fa'idodi da Cikakken Kwatancen Kwatancen Babban Tsarin Jiyya na Sama don Fasteners 

I. Babban Tsarin Jiyya na Sama ga Masu Fasteners da Babban Fa'idodin Su

1. Electrogalvanizing (ciki har da Blue-White Zinc da Zinc Launi)

Electrogalvanizing (sanyi galvanizing) wani tsari ne wanda ke ajiye nau'in tutiya na bai daya a saman filaye ta hanyar lantarki, ana samun su a nau'ikan irin su zinc-fari mai launin shuɗi da zinc launi. Ita ce hanya mafi ƙasƙanci da aka karɓo ta hanyar magani mai rahusa don masu ɗaure kasuwanci. Babban fa'idodinsa sun haɗa da fasahar balagagge, ƙarancin farashi, kauri mai sarrafawa (5-15μm), babban ƙarewa, da zaɓuɓɓukan launi masu yawa, yana sa ya dace da buƙatun buƙatun a cikin yanayin yanayin hana lalatawar haske na cikin gida. Don ƙananan maɗauran zaren zaren (misali, ƙasa M8), electrogalvanizing ba ya toshe zaren ko ramummuka, yana ba da kyakkyawan aikin taro, samun babban kasuwa, da gajerun zagayowar sarrafawa.

Ya kamata a lura cewa electrogalvanizing yana da ɗan haɗari na haɓakar hydrogen kuma yana aiki ne kawai ga masu ɗaure tare da taurin ƙasa HRC38. Bugu da ƙari, aikin anti-lalata yana da matsakaici. Gwajin feshin gishiri mai tsaka tsaki (NSS) na yau da kullun na electrogalvanizing shine yawanci sa'o'i 24-96, wanda za'a iya tsawaita zuwa sama da awanni 200 bayan jiyya tare da sealants na musamman, amma farashin zai karu da sau 5-8 daidai da haka.

2. Non Electrolytic Zinc Flake Coating (Dacromet/DACROMET)

Dacromet wani sabon nau'in sutura ne wanda ya ƙunshi foda na zinc, foda na aluminum, da chromic acid, wanda aka samo ta ta hanyar tsoma murfin da kuma yin burodi. Yana da tsarin da aka fi so don hana lalata na dogon lokaci a cikin yanayi mai tsanani, tare da manyan fa'idodi masu mahimmanci: babu haɗarin haɓakar hydrogen, yana sa ya dace da maɗauran ƙarfi mai ƙarfi; kyakkyawan juriya na lalata, tare da gwajin gwajin gishiri mai tsaka tsaki (NSS) na tsawon sa'o'i 500-800 don Layer ɗaya da sa'o'i 1500-2000 don nau'i biyu, tare da kyakkyawan juriya na zafin jiki (dogon lokaci ≤250 ℃); daidaitaccen sarrafa aikin gogayya, wanda ke tabbatar da daidaiton ƙarfi don haɗin kai mai mahimmanci kuma ya dace da yanayin yanayi tare da manyan buƙatu don amincin haɗin gwiwa.

Rashin hasaransa shine rashin daidaituwa ga ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan ƙananan M8 ko na'urorin haɗi na ciki, kamar yadda shafi na iya rinjayar taro; Matsayin matsakaicin farashi, wadatar kasuwa gabaɗaya, da Dacromet na gargajiya sun ƙunshi chromium hexavalent, don haka ana buƙatar kulawa da kiyaye muhalli.

3. Hot-Dip Galvanizing

Hot-tsoma galvanizing wani ma'auni tsari ne na waje nauyi anti-lalata al'amuran, kafa wani shafi ta nutse fasteners a zub da jini tutiya a 440-460 ℃. Babban fa'idodinsa shine mai kauri mai kauri (50-100μm), mannewa mai ƙarfi sosai, da ingantaccen juriya na lalacewa. Ko da scratches faruwa a kan surface, zai iya ci gaba da tsayayya da lalata ta hanyar hadaya anode sakamako na zinc, tare da wani NSS duration na 300-1000 hours bayan passivation. Wannan tsari yana fasalta matsakaicin farashi, kyakkyawar wadatar kasuwa, da ƙarancin haɗarin haɓakar hydrogen don babban ƙarfi mai ƙarfi, yana mai da shi yadu amfani da kayan aikin waje.

Iyakokinsa ba su da ƙarancin ƙarewa, ba su dace da madaidaicin yanayin taron ba; kananan-size threaded fasteners a kasa M8 bukatar na biyu tapping bayan jiyya, tasiri yadda ya dace; da aiki tsari na iya haifar da tempering taurin canje-canje, don haka an haramta yin amfani da 12.9-grade ko gami karfe sa sassa.

4. Maganin Black Oxide (Blueing).

Black oxide (blueing) magani yana samar da fim ɗin tetroxide mai kauri na 1-3μm (Fe₃O₄). Babban fa'idodinsa sune ƙananan farashi, gajerun hanyoyin sarrafawa, kuma babu wani tasiri akan daidaiton girman girman fastener, yana mai da shi dacewa da ainihin rigakafin tsatsa na ƙananan madaidaicin sassa a cikin gida mara lahani. Wannan tsari ba ya buƙatar wutar lantarki, ba ya haifar da haɗarin haɓakar hydrogen, kuma yana aiki azaman zaɓi na tattalin arziƙi don sassan da ba a fallasa su kamar abubuwan watsawa na ciki na kayan aikin injin da haɗa sassan tushen kayan aiki.

Its anti-lalata yi shi ne mafi rauni, tare da tsaka tsaki gishiri SPRAY gwajin duration na kawai 4-24 hours, wanda za a iya mika zuwa 48-72 hours bayan man nutsewa sealing, kawai saduwa da asali tsatsa rigakafin bukatun, da kuma surface sheki ne low, ba tare da wani kayan ado dukiya.

II. Daidaita Kwatancen Manyan Ayyuka na Babban Tsari

Don ƙarin nasiha na musamman, ana ba da shawarar shawarwarin fasaha na ƙwararru.
