Amashanyarazi ya Dacromet: Incamake Yuzuye 

1. Intangiriro

Gukaraba neza ni ibintu by'ingenzi muri sisitemu yo gufunga imashini. Iyi disiki yoroheje, iringaniye hamwe nu mwobo wo hagati ikwirakwiza umutwaro wa bolt cyangwa screw, kurinda ubuso bwahujwe kwangirika, no kunoza ubwizerwe bwihuza. Mu bidukikije byangirika - nk'ibishobora guhura n'ubushuhe, umunyu wo mu muhanda, imiti, cyangwa ubushyuhe bwo hejuru - ibyuma bisanzwe bitavuwe cyangwa bikozwe muri zinc bikozwe mu byuma akenshi byangirika imburagihe, bigatuma imbaraga zo gufatana, kunanirwa hamwe, cyangwa kubungabunga amafaranga menshi.

Kugira ngo iki kibazo gikemuke, hateguwe uburyo bwo kuvura hejuru. Mubikorwa byiza cyane ni Igikoresho cya Dacromet, sisitemu ya flake ya zinc-aluminiyumu ikoreshwa cyane kumesa ikozwe mumodoka, ubwubatsi, inyanja, ninganda zikoreshwa. Iyi ngingo itangiza Dacromet yogeje, isobanura tekinoroji yo gutwikira, ibintu byingenzi, ibipimo, ibyiza, porogaramu, no kugereranya nibindi bisoza.

2. Gutwika Dacromet ni iki?

Dacromet (DACROMET®) ni amashanyarazi adafite amashanyarazi, ashingiye ku mazi adashingiye ku mazi agizwe na zinc na aluminiyumu yatatanye muri chromate. Mu ntangiriro yakozwe mu myaka ya za 70 mu rwego rwo kurwanya ruswa y’umunyu ku binyabiziga, ikoreshwa hakoreshejwe uburyo bwa dip-spin, spray, cyangwa dip-drain nyuma yo kwangirika kwa alkaline no gusukura imashini (nta gutoragura aside ikoreshwa). Igipfundikizo noneho kirakira hafi ya 300 ° C, kibyara ubunini (ubusanzwe 5-15 mm), icyuma kimwe cya silver-cyera cyuma gifatanye neza nicyuma.

Uburyo bwayo bwo kurinda bukora muburyo butatu bwuzuzanya:

1. Kurinda inzitizi - gufunga zinc na aluminiyumu bigira inzitizi yumubiri irwanya ubushuhe, ogisijeni, hamwe na ruswa.
2. Kurinda Cathodic (ibitambo) - zinc ikora neza, ikingira ibyuma byimbere nubwo igifuniko cyangiritse gato.
3. Passivation - ibibyimba bya chromium bikora firime ihamye ya okiside itinda kwangirika no gufasha gufunga inenge ntoya.

3. Ibyingenzi byingenzi bya Dacromet Flat Wamesa

3.1 Kurwanya Ruswa Kuruta

Mu gupima umunyu utabogamye (ASTM B117 / ISO 9227), impuzu za Dacromet zisanzwe zigera ku masaha 500-1000 + zidafite ingese zitukura - mubisanzwe zikubye inshuro 5-10 ugereranije na zinc electroplating yubunini busa. Ibipimo birebire cyane (Grade B cyangwa uburebure bwimbitse) birashobora kurenza amasaha 1.000, bifasha ubuzima bwa serivisi yimyaka 5-15 cyangwa irenga mugihe gikabije cyo hanze cyangwa munsi yabantu.

3.2 Kurwanya Ubushyuhe Bwinshi

Igifuniko kigumana ubusugire bwacyo hamwe nuburinzi bugera kuri 300 ° C (572 ° F). Ibi bituma Dacromet yogeje ikwiranye nibice biri hafi ya moteri, sisitemu yo kuzimya, guteranya feri, hamwe nandi masoko yubushyuhe aho isahani ya zinc isanzwe yoroshye, igashishwa, cyangwa igatakaza ruswa.

3.3 Nta hydrogène yinjiza

Kubera ko inzira itari electrolytike kandi ikirinda gufata aside, Dacromet nta ngaruka ishobora guterwa na hydrogène. Iyi ni akarusho gakomeye kubwogeje imbaraga nyinshi (gukomera kwicyiciro cya 200 HV, 300 HV no hejuru) no gukoreshwa hamwe na bolts-tensile (Grade 10.9 na hejuru), aho hydrogène iterwa na hydrogène ihangayikishijwe cyane no kurangiza amashanyarazi gakondo.

3.4 Ntoya, Filime imwe ninyungu zinyongera

Hamwe nubusanzwe bwa firime yumye yuburebure bwa 5-12 mm gusa, igifuniko ntigihindura cyane ibipimo bikomeye cyangwa umurongo wogosha, bikomeza gukora neza kandi bifatanye. Izindi nyungu zirimo kwizirika cyane kuri substrate, gusiga irangi neza, coefficente igenzurwa no guterana amagambo (cyane cyane iyo hashyizweho ikote ryamavuta), hamwe na bimetallic ihuza nibice bya aluminium.

4. Ibipimo, Ibikoresho, nibisobanuro

Gukaraba neza kwa Dacromet bikozwe mubipimo mpuzamahanga bizwi cyane, harimo DIN 125, ISO 7089, DIN 9021, na ANSI / ASME B18.22.1. Ibikoresho fatizo nibyuma byuma bya karubone bitangwa mubyiciro bikomeye nka 100 HV, 140 HV, 200 HV, cyangwa 300 HV; ibyuma bidafite ibyuma nabyo birahari kubisabwa byihariye. Ingano isanzwe iva kuri metero ntoya (M1.6 / Φ1.7 mm) kugeza ku bunini bunini (M160 / Φ165 mm no hejuru yayo), ikubiyemo ibipimo bisanzwe kandi binini-byo hanze-diameter (fender). Ibyiciro byo gutwikira mubisanzwe ni Icyiciro cya A (hafi 24 g / m²) cyangwa Icyiciro B (hafi 36 g / m²), gitangwa kenshi hamwe namakoti yabigenewe ateza imbere amavuta cyangwa imikorere ya ruswa. Abatanga ibyamamare batanga raporo yikizamini cyumunyu-spray, gupima ubunini, hamwe nimpamyabumenyi.

5. Inyungu hejuru yimyenda isanzwe

• Igihe kinini cya serivisi - kuburyo bugaragara kurinda ruswa bigabanya cyane intera yo kubungabunga hamwe nigiciro cyo gusimbuza.
• Ufite umutekano wimbaraga zikomeye - kubura burundu ibyago byo kwinjiza hydrogène.
• Ibipimo bifatika - firime yoroheje irinda kwihanganira no guhuza imigozi ikwiye.
• Ubushyuhe bukabije - imikorere yizewe ahantu hazamutse-ubushyuhe.
• Ikiguzi cyubuzima bwiza - nubwo igiciro cyambere cyibiciro kiri hejuru yibyingenzi bya zinc, igihe kirekire cyumurimo no kugabanuka kumasaha mubisanzwe bitanga igiciro gito cya nyirubwite.

6. Ibisanzwe

Imodoka: Chassis, guhagarikwa, munsi yumuntu, umunaniro, hamwe na moteri ifata ibyuma byumunyu wumuhanda nubushuhe. Abatanga OEM benshi hamwe na Tier-1 batanga cyane cyane ibifuniko bya zinc-flake nka Dacromet kubwo gukaraba no gufunga.

Ubwubatsi & Ibikorwa Remezo: Guhuza ibyuma byubaka, ibiraro, tunel, urubuga rwo hanze, scafolding, uruzitiro, hamwe nibikoresho byububiko byo hanze bigomba kwihanganira igihe kirekire cyo hanze.

Indi nzego: Ibikoresho byo mu nyanja no ku nkombe, imashini z’ubuhinzi n’ubwubatsi, sisitemu ya gari ya moshi n’ubwikorezi, iminara y’ingufu n’umuyaga na nacelles, ibicuruzwa byera n’ibikoresho, hamwe n’inteko rusange y’inganda ikorera ahantu habi cyangwa h’ubushuhe bwinshi.

7. Kugereranya nubundi buryo bwo gutwikira

Zinc amashanyarazi ihendutse kandi iraboneka henshi, nyamara itanga imbaraga nke zo kurwanya umunyu-spray (mubisanzwe amasaha 72-200) kandi itwara hydrogène-iterwa no kugabanuka kubice bikomeye.

Ashyushye cyane itanga uburinzi buhebuje bwo kurinda ruswa hamwe nigitambo cyo gutamba, ariko igipfundikizo cyinshi gishobora kubangamira urudodo rukwiranye nukuri neza, bigatuma bidakwiranye neza cyangwa byogejwe.

Ubundi sisitemu ya zinc-flake (kurugero Geomet®) gutanga imikorere mubyiciro rusange nka Dacromet. Ihitamo rya nyuma akenshi riterwa na OEM yihariye, amahitamo ya topcoat aboneka, hamwe nuruhererekane rwo gutanga isoko. Muri rusange, Dacromet itanga uburinganire bwiza bwa firime yoroheje, irwanya ruswa nyinshi, ituze ryumuriro, nubwisanzure bwo kwinjiza hydrogène.

8. Umwanzuro

Amashanyarazi ya Dacromet ahuza inyungu zogukoresha ibikoresho bisanzwe byogejwe - gukwirakwiza imizigo no kurinda ubuso - hamwe na flake ya zinc-aluminiyumu igezweho itanga imbaraga zo kurwanya ruswa, imikorere yubushyuhe bwo hejuru, n'umutekano kubikoresha imbaraga nyinshi. Filime yabo yoroheje, imwe, yerekanwe mumodoka, hamwe nigihe kirekire cyo gukora bituma bahitamo guhitamo mumodoka, ubwubatsi, inyanja, ninganda nini.

Mugihe cyo kwerekana aba bakaraba, hagomba kwitonderwa urwego rukenewe rukomeye, urwego rupima (DIN, ISO, cyangwa ANSI), uburemere bwikigereranyo cyangwa urwego, hamwe nibikenewe byose hejuru yamakoti. Gufatanya nababikora bashobora gutanga amakuru yikizamini cyumunyu-spray hamwe nimpamyabushobozi ifasha kwemeza imikorere yizewe muri serivisi. Mubisabwa aho ruswa, ubushyuhe, cyangwa imbaraga nyinshi aribintu bikomeye, Dacromet isize isabune yogeje ikomeza kuba igisubizo cyemewe kandi cyigiciro.
