1. Gabatarwa

A cikin aikin injiniya da masana'antu na zamani, amincin haɗin gwiwar da aka kulle yana da mahimmanci ga daidaiton tsari, aminci, da aiki na dogon lokaci. Nau'i na al'ada sau da yawa suna fama da lalata, musamman a cikin yanayi mai tsauri da ya shafi danshi, gishiri, sinadarai, ko yanayin zafi. Dacromet flange bolts suna magance waɗannan ƙalubalen ta hanyar haɗa ƙwanƙwasa na musamman na zinc-aluminum flake tare da fa'idodin injin ƙirar ƙirar flange.

A Dacromet flange bolt ne mai babban aiki fastener cewa integrates ginannen a cikin wanki-kamar flange karkashin kai tare da nonelectrolytic zinc-flake shafi da aka sani da Dacromet (ko zinc flake rufi tsarin samu daga gare ta). Wannan haɗin yana ba da juriya na musamman na lalata, daidaitaccen ƙarfi, da 'yanci daga haɓakar hydrogen - yana mai da shi dacewa musamman don aikace-aikacen ƙarfi mai ƙarfi a cikin motoci, gini, ruwa, makamashi, da sassan masana'antu.

2. Menene Dacromet Coating?

Dacromet shine tushen ruwa, inorganic zinc-aluminum flake shafi tsarin da aka samo asali a cikin 1970s. Ya ƙunshi flakes na zinc da aluminum da aka dakatar a cikin abin ɗaure chromate (ko chromium-free). Ana amfani da murfin ta hanyar dip-spin, spray, ko hanyoyin nutsewa sannan kuma a warke a yanayin zafi mai tsayi (yawanci a kusa da 300 ° C), yana samar da siriri, mai yawa, fim mai kariya mai yawa.

Mahimman halayen sutura sun haɗa da:

Kaurin fim mai kauri: Yawanci 4-12 μm (yawanci 6-8 μm), wanda ke kula da madaidaicin haƙurin zaren.

Shamaki + Kariyar hadaya: Filayen ƙarfe masu haɗaka suna haifar da shinge na jiki yayin da zinc ke ba da kariya ta galvanic (hadaya).

Babu hydrogen embrittlement: Tsarin da ba na lantarki ba yana guje wa tsinkar acid da electrolysis, yana kawar da haɗarin jinkirta jinkirin da hydrogen ya haifar a cikin ƙananan ƙarfe.

Juriya mai zafi: Barga har zuwa kusan 300°C ci gaba da zafin sabis.

Bayyanar: Ƙarfe azurfa-launin toka matte gama.

Lura cewa "Dacromet" sunan alamar kasuwanci ne; irin wannan tsarin zinc-flake (irin su Geomet, wanda ba shi da chromium) ana amfani da su sosai a yau don saduwa da ƙa'idodin muhalli na zamani (RoHS, REACH, ELV).

3. Menene Flange Bolts?

Kullin flange (wanda kuma ake kira flanged hex head bolt ko frame bolt) yana da fasalin madauwari madauwari a ƙarƙashin shugaban hexagonal wanda ke aiki azaman mai wanki. Wannan zane yana rarraba nauyin ƙwanƙwasa a kan wani yanki mafi girma, yana rage haɗarin haɗawa a cikin kayan da aka haɗa, inganta juriya ga sassaukar girgiza, kuma sau da yawa yana kawar da buƙatar mai wanki daban.

Nau'o'in gama-gari sun haɗa da:

Hex flange kusoshi (mafi na kowa)

Serared flange bolts (tare da serration karkashin-kai don hana jujjuyawar)

Socket head ko wasu bambance-bambancen flange na musamman

Lokacin da aka haɗe shi da murfin Dacromet, waɗannan kusoshi suna ba da ingantaccen aikin injina da kuma kyakkyawan yanayin muhalli.

4. Kwatanta da Rubutun gama-gari

Tebur mai zuwa yana taƙaita bambance-bambancen aiki na yau da kullun:

Dukiya	Dacromet	Electro-Zinc	Hot-Dip Galv.	Bakin
Salt Spray (hrs)	1,000-1,500+	100-300	500-1,000+	Mahimmanci
Rufi Kauri	4-12 m	5-15 m	40-100+ μm	N/A
H Hatsarin Hatsari	Babu	Babban (na ≥10.9)	Ƙananan-Matsakaici	Babu
Max Temp Temp.	~300°C	~ 100-120 ° C	~200°C	Babban
Tasiri Fit Fit	Karamin	Ƙananan	Mahimmanci	Babu

Lura: Aiki na gaske ya bambanta tare da darajar shafi, kauri, topcoat, da yanayin muhalli. Tsarukan flake na zinc marasa Chromium (misali, Geomet) suna ba da irin wannan kariyar lalata yayin saduwa da ƙaƙƙarfan ƙa'idodin muhalli.

5. Manyan Yankunan Aikace-aikace

Dacromet flange bolts ana amfani da su sosai a cikin kayan aikin chassis, tsarin dakatarwa, hawan injin, taron birki, tsarin shaye-shaye, da tsarin jiki. Suna jure wa gishirin hanya, hawan keke mai zafi, girgiza, da yanayin zafi mai tsayi yayin da suke samar da abin dogaro mai dogaro.

A cikin gadoji, hasumiya mai watsawa, sifofin ƙarfe, da wuraren bakin teku, waɗannan kusoshi suna ba da kariya ta dogon lokaci daga lalatawar yanayi kuma suna rage mitar kulawa.

Tushen injin turbin daga bakin teku, tsarin hawan hasken rana, ginin jirgi, da kayan aikin tashar jiragen ruwa suna amfana daga babban juriya na fesa gishiri da kuma iya yin suturar hadaddun geometries iri ɗaya.

Kayan aikin da aka fallasa ga takin zamani, sinadarai, danshi, da abrasion-kamar injinan noma, famfo, bawuloli, da na'urorin sarrafawa—yawan ƙayyadaddun na'urorin flange mai rufin Dacromet don tsawan rayuwar sabis.

6. Maki na gama gari, Ma'auni, da Jagorar Zaɓi

Azuzuwan dukiya: Dacromet flange bolts suna samuwa a cikin azuzuwan dukiya 4.8, 8.8, 10.9, da 12.9 (metric), kazalika da Grade 5 da Grade 8 (sarauta). Matsayi mai ƙarfi (10.9 / 12.9) musamman suna amfana daga rashin haɗarin haɓakar hydrogen.

Ma'auni mai girma: Nassoshi gama gari sun haɗa da ma'auni na ma'auni na ISO metric flange, DIN, GB (Sinanci), da ASME/ANSI don jerin inch.

Bayani dalla-dalla: Ana yin ƙayyadaddun ayyuka sau da yawa ta mafi ƙarancin ɗaukar nauyi (misali, Grade A ≈ 24 g/m², Grade B ≈ 36 g/m²) da buƙatun fesa gishiri. Za a iya ƙara manyan riguna don ingantacciyar mai, launi, ko ƙarin kariyar shinge.

Nasihun zaɓi: Daidaita tsarin sutura zuwa nau'in lalata na muhalli (misali, C3-C5 ta ISO 12944). Don ƙaƙƙarfan tsarin haɗin gwiwa, tabbatar da bayanan tashin hankali tare da takamaiman shafi da suturar saman. Fi son tsarin marasa chromium lokacin da ake buƙatar bin muhalli.

7. Shigarwa da La'akari da Aiki

Kula da kulawa: Kodayake murfin yana da mannewa mai kyau, kauce wa lalacewar injiniya mai tsanani a lokacin sarrafawa da shigarwa.

Ikon wutar lantarki: Yi amfani da ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun abin da mai siyar ya bayar. Tsarukan Dacromet mai mai mai suna samar da daidaiton nauyin matsi fiye da suturar tutiya maras mai.

Daidaituwa: Dacromet gabaɗaya ya dace da yawancin gasket da kayan rufewa kuma ana iya yin fentin fiye da kima idan an buƙata.

Dubawa: Duban gani don ci gaban shafi da gwajin mannewa (inda aka ƙayyade) ya kamata ya zama wani ɓangare na kulawar inganci.

8. Kammalawa

Dacromet flange bolts suna wakiltar babban balagagge, babban aiki mai ɗaukar nauyi wanda ya sami nasarar daidaita kariyar lalata, amincin injina, da daidaitaccen tsari. Ta hanyar kawar da haɗarin haɓakar hydrogen yayin isar da aikin fesa gishiri wanda ya fi na tutiya na yau da kullun, sun zama zaɓin da aka fi so don buƙatar aikace-aikace a sassan motoci, makamashi, gini, da masana'antu.

Yayin da ka'idojin muhalli ke ci gaba da fitar da tsarin ba da chromium-flake na zinc, fasahar tana ci gaba da haɓakawa yayin da take riƙe ainihin fa'idodinta. Lokacin da aka keɓance kayan ɗamara don yanayin lalata ko yanayin zafin jiki - musamman inda ake buƙatar maki masu ƙarfi - Dacromet (ko daidai zinc-flake) ƙwanƙolin flange mai rufi ya kamata a yi la’akari da shi sosai azaman ingantaccen bayani mai inganci da tsada akan rayuwar sabis na taron.

Ana ƙarfafa injiniyoyi da masu siye don tuntuɓar masu samar da kayan shafa don cikakkun takaddun bayanan fasaha, ƙididdigar ƙira, da rahoton gwajin fesa gishiri musamman ga tsarin da aka zaɓa da buƙatun aikace-aikace.

Ba Da. Na gaba.
