Dacromet Flat Washers: Cikakken Bayani 

1. Gabatarwa

Flat washers sune mahimman abubuwan haɗin gwiwa a cikin tsarin ɗauren injina. Wadannan siraran, fayafai masu lebur tare da rami na tsakiya suna rarraba nauyin ƙugiya ko dunƙule, suna kare abubuwan da aka haɗa daga lalacewa, da inganta amincin haɗin gwiwa. A cikin mahalli masu lalacewa-kamar waɗanda aka fallasa ga danshi, gishirin hanya, sinadarai, ko yanayin zafi mai tsayi-daidaitattun waɗanda ba a kula da su ba ko na'urar wanke ƙarfe da aka ɗora da zinc sau da yawa suna lalatawa da wuri, wanda ke haifar da raguwar ƙarfi, gazawar haɗin gwiwa, ko kulawa mai tsada.

Don magance wannan ƙalubalen, an haɓaka jiyya na gaba. Daga cikin mafi inganci shine Dacromet shafi, Tsarin flake na zinc-aluminum wanda aka yadu ana amfani da shi ga masu wanki masu lebur don motoci, gini, marine, da amfani da masana'antu. Wannan labarin yana gabatar da Dacromet flat washers, yana bayanin fasahar sutura, mahimman kaddarorin, ma'auni, fa'idodi, aikace-aikace, da kwatance tare da madadin ƙarewa.

2. Menene Dacromet Coating?

Dacromet (DACROMET®) ba na lantarki ba ne, rufin inorganic na tushen ruwa wanda ya ƙunshi tutiya da flakes na aluminium wanda aka tarwatsa a cikin mai ɗaure chromate. An samo asali ne a cikin 1970s don magance lalata-gishiri a kan ababen hawa, ana amfani da shi ta hanyar tsoma baki, feshi, ko hanyoyin tsomawa bayan lalatawar alkaline da tsabtace injin (ba a yi amfani da pickling acid). Sa'an nan kuma an warke murfin a kusan 300 ° C, yana samar da siririn (yawanci 5-15 μm), fim ɗin ƙarfe na azurfa-launin toka na yau da kullun wanda ke manne da ƙarfen karfe.

Tsarin kariyarsa yana aiki ta hanyoyi guda uku:

1. Kariyar shinge - tutiya mai cike da flakes na aluminium suna haifar da shingen jiki mai yawa daga danshi, iskar oxygen, da abubuwan lalata.
2. Katodic (hadaya) kariya - Zinc yana lalata da kyau, yana ba da kariya ga karfen da ke cikin ƙasa ko da an ɗan lalata murfin.
3. Abin sha'awa - mahadi na chromium suna haifar da tsayayyen fina-finan oxide waɗanda ke rage jinkirin lalata kuma suna taimakawa rufe ƙananan lahani.

3. Key Properties na Dacromet Flat Washers

3.1 Babban Juriya na Lalata

A cikin gwajin fesa gishiri mai tsaka-tsaki (ASTM B117 / ISO 9227), suturar Dacromet yawanci suna samun sa'o'i 500-1,000+ ba tare da tsatsa ba - yawanci sau 5-10 fiye da na yau da kullun na zinc electroplating na kauri. Ma'auni mafi girma (Grade B ko bambance-bambancen kauri) na iya wuce sa'o'i 1,000, yana tallafawa rayuwar sabis na shekaru 5-15 ko fiye a cikin matsanancin yanayi na waje ko na ƙasa.

3.2 Babban Juriya na Zazzabi

Rufin yana riƙe da mutuncinsa da kaddarorin kariya har zuwa kusan 300°C (572°F). Wannan yana sa masu wanki na Dacromet su dace da abubuwan da ke kusa da injuna, tsarin shaye-shaye, majalissar birki, da sauran hanyoyin zafi inda talakawan zinc plating zai yi laushi, bawo, ko rasa juriyar lalata.

3.3 Babu Ruwan Ruwa

Saboda tsarin ba electrolytic ba ne kuma yana guje wa tattarawar acid, Dacromet ba ya gabatar da haɗarin haɓakar hydrogen. Wannan babbar fa'ida ce ga masu wanki masu ƙarfi (masu taurin 200 HV, 300 HV da sama) kuma don amfani tare da manyan kusoshi masu tsayi (Grade 10.9 da mafi girma), inda fashewar hydrogen-induced yana da matukar damuwa tare da gamawa na gargajiya na lantarki.

3.4 Siriri, Fim ɗin Uniform da Ƙarin Fa'idodi

Tare da kaurin fim ɗin bushe-bushe na 5-12 μm kawai, rufin ba ya canza mahimmancin girma ko sharewar zaren, yana kiyaye daidaitaccen dacewa da aikin matsewa. Ƙarin fa'idodin sun haɗa da manne mai ƙarfi ga ma'auni, kyakkyawan fenti, daidaitawar juzu'i (musamman lokacin da aka yi amfani da suturar mai mai mai), da daidaituwar bimetallic tare da abubuwan aluminum.

4. Ma'auni, Kayayyaki, da Ƙididdiga

Dacromet lebur washers ana kerarre su zuwa manyan ka'idojin girma na duniya, gami da DIN 125, ISO 7089, DIN 9021, da ANSI/ASME B18.22.1. Tushen kayan suna da farko carbon karfe kawota a taurin maki kamar 100 HV, 140 HV, 200 HV, ko 300 HV; Hakanan ana samun nau'ikan bakin-karfe don buƙatu na musamman. Girman girma yawanci kewayo daga ƙananan diamita na awo (M1.6 / Φ1.7 mm) zuwa manyan masu girma dabam (M160 / Φ165 mm da bayan), suna rufe duka daidaitattun ma'auni da manyan diamita (fender). Rubutun maki yawanci Grade A (kimanin 24 g/m²) ko Grade B (kimanin 36 g/m²), akai-akai ana bayarwa tare da riguna na zaɓi waɗanda ke ƙara haɓaka aikin lalata ko lalata. Mashahuran masu samar da kayayyaki suna ba da rahotannin gwajin fesa gishiri, ma'aunin kauri, da takaddun shaida.

5. Fa'idodi akan Rubutun Al'ada

• Tsawaita rayuwar sabis - Kariyar lalata ta fi tsayi tana rage tazarar kulawa da farashin canji.
• Amintacce don masu ɗaure masu ƙarfi - cikakken rashi na hydrogen embrittlement hadarin.
• Matsakaicin daidaito - fim ɗin bakin ciki yana kiyaye haƙuri da haɗin kai mai dacewa.
• Zaman lafiyar thermal - ingantaccen aiki a wurare masu tsayi-zazzabi.
• Kyawawan farashin rayuwa - ko da yake farashin naúrar farko ya fi ginshiƙan tutiya na asali, tsawon rayuwar sabis da rage raguwar lokaci yakan haifar da ƙarancin ƙimar mallakar.

6. Aikace-aikace na yau da kullun

Mota: Chassis, dakatarwa, karkashin jiki, shaye-shaye, da na'urorin injin injin da aka fallasa ga gishiri da danshi na hanya. Yawancin OEMs da masu samar da Tier-1 na buƙatar musamman kayan kwalliyar zinc-flake kamar Dacromet don masu wanki masu mahimmanci da masu ɗaure.

Gina & Kayan Aiki: Hanyoyin haɗin ginin ƙarfe, gadoji, ramuka, dandamali na teku, shinge, shinge, da kayan aikin gine-gine na waje waɗanda dole ne suyi tsayin daka a waje.

Sauran sassa: Kayan aikin ruwa da na bakin teku, injinan noma da gine-gine, layin dogo da tsarin sufuri, hasumiyai masu ƙarfin iska da naceles, farar kaya da na'urori, da taron masana'antu na gabaɗaya waɗanda ke aiki a cikin gurɓataccen yanayi ko ƙarancin ɗanshi.

7. Kwatanta da Madadin Rufe

Zinc electroplating ba shi da tsada kuma yana da yawa, duk da haka yana ba da iyakacin juriya na fesa gishiri (yawanci awanni 72-200) kuma yana ɗaukar haɗarin haɓakar hydrogen akan sassa masu ƙarfi.

Hot-tsoma galvanizing yana ba da kyakkyawan kariyar lalata da halayen sadaukarwa, amma in mun gwada da kauri mai kauri na iya tsoma baki tare da dacewan zaren da daidaiton girma, yana sa ya zama ƙasa da dacewa da daidaito ko ƙananan wanki.

Sauran zinc-flake tsarin (misali Geomet®) yana ba da aiki a cikin aji ɗaya kamar Dacromet. Zaɓin ƙarshe yakan dogara da takamaiman takamaiman OEM, zaɓuɓɓukan saman riguna, da sarƙoƙin samar da yanki. Gabaɗaya, Dacromet yana ba da ingantacciyar ma'auni na kauri na fim ɗin bakin ciki, babban juriya na lalata, kwanciyar hankali na zafi, da 'yanci daga haɓakar hydrogen.

8. Kammalawa

Dacromet lebur washers sun haɗu da fa'idodin inji na masu wanki na al'ada - rarraba kaya da kariyar ƙasa - tare da ci-gaba mai ɗorewa na tutiya-aluminum flake wanda ke ba da ingantaccen juriya na lalata, babban yanayin zafi, da aminci ga aikace-aikacen ƙarfi mai ƙarfi. Fim ɗinsu na bakin ciki, iri ɗaya, tabbataccen ƙa'idar kera, da tsawon rayuwar sabis ya sa su zaɓi zaɓin da aka fi so a cikin abubuwan kera motoci, gine-gine, ruwa, da manyan masana'antu.

Lokacin zayyana waɗannan wankin, ya kamata a ba da hankali ga ƙimar taurin da ake buƙata, daidaitaccen ƙima (DIN, ISO, ko ANSI), nauyin sutura ko daraja, da duk wani buƙatu na manyan riguna masu lubricated. Haɗin kai tare da masana'antun waɗanda za su iya ba da bayanan gwajin fesa gishiri da takaddun kayan aiki yana taimakawa tabbatar da ingantaccen aiki a cikin sabis. A cikin aikace-aikace inda lalata, zafi, ko babban ƙarfi ke da mahimmancin abubuwa, masu wanke-wanke mai rufin Dacromet sun kasance tabbatacce kuma ingantaccen bayani.
