Dacromet Hex Bolts Iyobora Umuhengeri Ukurikira wo Kurwanya Ruswa 

Bitandukanye na zinc gakondo ya zinc, inzira ya Dacromet ntabwo yinjiza hydrogène muri substrate. Ibi bivanaho ibyago byo kwinjiza hydrogène - inyungu ikomeye mugihe utwikiriye imbaraga zikomeye za hex zo mu cyiciro cya 8.8, 10.9, na 12.9. Igisubizo ni a rust-hex bolt igumana ubunyangamugayo bwuzuye mugihe itanga ruswa iruta kure iyisanzwe isanzwe.

Impamvu Hex Bolts Yunguka Byinshi muri Dacromet

Hex bolts- cyane cyane ibyuma biremereye byubatswe - byerekanwe cyane mubiraro, iminara yingufu zumuyaga, imashini ziremereye, hamwe na chassis yimodoka. Izi porogaramu zisaba kwizirika zihuza neza imyitwarire ya torque-tension hamwe nimyaka-mirongo kurwanya ruswa ubuzima. Dacromet yujuje ibisabwa byombi:

• Ubwishingizi bumweku nsanganyamatsiko igoye ya geometrie idafite ubwubatsi bujyanye na hot-dip galvanizing, ikomeza uburinganire bwukuri hamwe nu murongo.
• Coefficient igenzurwa(mubisanzwe μ = 0.12–0.18 hamwe na topcoat), ituma umutwaro uhoraho hamwe nibikorwa byinshi.
• Nta hydrogène ishobora guterwa, gukora Dacromet ikunzwe Kurwanya ingesekurangiza kuri-tensile hex bolts ikoreshwa mumutekano-uhuza umutekano.
• Kurwanya ubushyuhe bugera kuri 300 ° C., birenze kure imipaka ifatika ya zinc electroplated.

Imikorere ya ruswa: Dacromet na Coatings gakondo

Kwipimisha muri laboratoire yigenga byerekana ko ibyo Dacromet-yometse kuri hex Kurusha zinc electroplated zinc hamwe na hot-dip ya galvanised yiziritse mumashanyarazi atabogamye (ASTM B117 / ISO 9227) hamwe nibizamini bya ruswa. Ikigereranyo gikurikira cyerekana muri make ibisubizo bisanzwe kuri sisitemu yo gutwikira:

Imbonerahamwe 1. Kugereranya imikorere yingenzi yo kurwanya ruswa kuri hex bolts (indangagaciro za laboratoire).

Mu bushakashatsi bumwe bwavuzwe cyane kuri ASTM A490 imbaraga zikomeye zubatswe, ibice bya Dacromet byerekanwe ingese zitukura nyuma yamasaha 1.000 yumunyu-spray uhoraho, mugihe imashini ya galvanisike yerekanaga ingese zitukura zirenga 85% hejuru yingenzi. Ndetse nyuma yamasaha 5.000, ingero za Dacromet zerekanaga ingese zitukura zigera kuri 6% gusa - zirusha cyane imbaraga zishyushye zishyushye zigeze hafi ya ruswa.

Siyanse Yihishe Kurinda Kurwanya Rust

Ntibisanzwe kurwanya ruswa imikorere ya Dacromet ikomoka muburyo butatu bwuzuzanya:

1. Kurinda inzitizi- Gufunga zinc na aluminiyumu bigira ingabo yuzuye, igizwe ningingo nyinshi ibuza ubushuhe na ion ya chloride.
2. Kurinda ibitambo (cathodic)- Zinc flake ikunda kwangirika, kurinda ibyuma byimbere nubwo igifuniko cyangiritse mukarere.
3. Passivation / kwikiza- Chromium-oxyde ivanze muri binder ikora firime ihamye itinda cyane kwangirika kwiterambere.

Isoko ryo kureba hamwe ninganda Inganda

Mugihe ibikorwa remezo byisi byihuta kandi urubuga rwimodoka rwimuka rugana ibyuma bikomeye, bisaba kwizerwa kurwanya ruswa na ingese ibisubizo byihuse bikomeje kwiyongera. Indorerezi mu nganda zerekana ibintu byinshi bishimangira:

• Gukura- Ibipimo byinshi byubwubatsi (harimo ivugururwa rijyanye na ASTM F3125 yubatswe) ubu tumenye neza sisitemu ya zinc-flake nka Dacromet nkibishobora kwemerwa muburyo busanzwe bwa galvanizing kubikorwa byimbaraga nyinshi.
• Ibitekerezo birambye- Amazi ya Dacromet ashingiye kumazi atanga imyanda itari mike kurusha imirongo myinshi ya electroplating, ihuza no gukaza amategeko agenga ibidukikije.
• Igiciro cyose cya nyirubwite- Nubwo igiciro cyibice gishobora kuba hejuru kurenza plaque ya zinc, igihe kinini cya serivisi no kugabanya kubungabunga Dacromet hex kenshi utange ubuzima buke mubuzima bwangirika.

Ubuyobozi bufatika kubisobanura

Iyo uhitamo Dacromet-yometse kuri hex, injeniyeri agomba kugenzura igipimo cyo gutwikira (urugero, Icyiciro A cyangwa B ukurikije uburemere bwa coating), akemeza guhuza amavuta yo kwisiga ayo ari yo yose hamwe n’umubyigano wa torque-tension, kandi akemeza ko ibihindu byombi hamwe nimbuto / byogejwe byakira neza birangiye. Kubika neza no gufata neza bikomeza kuba ingenzi: mugihe igifuniko ari kinini Kurwanya ingese, ibyangiritse mbere yo kwishyiriraho birashobora kugabanya kurinda.

Umwanzuro

Tekinoroji ya Dacromet imaze gukura kuva mumodoka yihariye irangiza muburyo rusange kurwanya ruswa igisubizo kubikorwa-byo hejuru hex bolts. Ihuza ryayo ridasanzwe rya firime yoroheje, kutagira hydrogène, ubushobozi bwubushyuhe bwo hejuru, hamwe no kwerekana amasaha ibihumbi-amasaha menshi yo kurwanya umunyu-spray birwanya umwanya wambere aho ariho hose. ingese kwizerwa ntabwo biganirwaho.

Nka banyiri ibikorwa remezo, abashinzwe guteza imbere umuyaga, hamwe n’imodoka OEM bakomeje gushyira imbere kuramba no kugabanya kubungabunga, Dacromet hex Biteganijwe gufata umugabane wagutse wisoko rya premium yihuta-gutanga Kurwanya ingese imikorere yubuhanga bugezweho busaba.
