1. Intangiriro

Mubikorwa bigezweho byinganda, ubunyangamugayo burambye bwingingo zifatika biterwa cyane ningirakamaro kurinda ruswa na imikorere yo kurwanya ingese. Gakondo ya zinc hamwe na hot-dip galvanizing akenshi bigabanuka mubidukikije bikaze cyane nkibikorwa remezo byo ku nkombe, urubuga rwo hanze, uruganda rukora imiti, hamwe n’ibinyabiziga bitwara ibinyabiziga bigaragarira umunyu wo mu muhanda. Dacromet flange komatanya ibyiza byuburyo bwa flange-umutwe igishushanyo mbonera ingese na kurwanya ruswa imiterere ya zinc-aluminium flake.

Dacromet (izwi kandi nka zinc flake coating) ni uburyo bwo kuvura amazi adafite amashanyarazi, ashingiye kumazi. Irabika urwego ruto ariko rukora neza cyane rwa zinc na aluminiyumu ihujwe na matrix ya chromate, itanga bidasanzwe kurinda inzitizi, kurinda ibitambo, na kwikiza passivation. Byakoreshejwe kuri flange bolts, iyi coating itanga igihe kirekire cyizewe Kurwanya ingese utabangamiye urudodo rukwiye, urumuri rwukuri, cyangwa kwinjiza hydrogène ibyago.

Igicapo 1. Imbaraga-nyinshi Dacromet-yometse kuri bolts hamwe na silver-gray imwe irwanya ruswa

2. Flange Bolts hamwe na tekinoroji ya Dacromet

Ikibaho cya flange kirimo uruziga ruzengurutse munsi yumutwe wa mpande esheshatu zikora nkuwiyuhagira. Igishushanyo gikwirakwiza imbaraga zo gufatira hejuru yubunini bunini, kugabanya kwangirika kwubutaka no kunoza kurwanya ihindagurika ryatewe no guhindagurika. Iyo ibi byuma byakira Dacromet, igiteranyo gitanga umusaruro wihuta utanga imashini yizewe kandi isumba izindi Kurwanya ingese na Kurwanya ruswa imikorere. Ipitingi yoroheje (mubisanzwe 5-12 mm) ikomeza umurongo wa geometrie.

2.1 Igikoresho cyo gutwikira hamwe nuburyo bukoreshwa

Dacromet ni ikwirakwizwa ryamazi ya zinc flake, flake ya aluminium, na oxyde ya chromium. Inzira itari electrolytike mubisanzwe ikubiyemo: (1) gusukura hejuru hatarimo aside irike; (2) gusaba ukoresheje dip-spin, dip-drain cyangwa spray; na (3) gukiza hafi 300 ° C kugirango uhuze flake mubice byuzuye. Ibyuma bivamo ifeza-ibara rya firime itanga ibice byinshi Kurwanya okiside kandi byizewe inzitizi.

2.2 Uburyo bwo Kurinda Ruswa

Dacromet igera kubintu bidasanzwe kurwanya ruswa imikorere binyuze muburyo butatu bwo guhuza:

Kurinda inzitizi: Gufunga zinc na aluminiyumu bitera inzitizi yumubiri ya labyrintine ibuza amazi, ogisijeni, hamwe na ion zibora nka chloride.
Kurinda Ibitambo (Cathodic): Zinc flake ikunda kwangirika, ikora nka anode yigitambo irinda insimburangingo yicyuma kutagira ingese.
Passivation no Kwikiza: Chromate ivanze ikora firime ya pasiporo kandi irashobora kwimuka mukantu gato, itanga ubudahwema kwirinda ingesen'ubushobozi bwo kwikosora.

3. Ibyiza byingenzi bya Dacromet Flange Bolts

Ugereranije nubuvuzi busanzwe busanzwe, Dacromet flange bolts itanga ihuza ryihariye ryibyiza:

Kurwanya umunyu uruta iyindi: Mubisanzwe birenga amasaha 1.000.200 yo gupima umunyu utabogamye (ISO 9227) udafite ingese itukura - akenshi bikubye inshuro 7-10 kurenza amashanyarazi.
Impanuka ya Zeru Hydrogen: Inzira itari electrolytike ikuraho hydrogène, bigatuma Dacromet iba nziza kumbaraga zikomeye Icyiciro cya 8.8, 10.9, na 12.9.
Gitoya, Igipimo gifatika: Kuri 5-12 mm gusa, igipfundikizo kibika umurongo wukuri kandi cyemerera utubuto dusanzwe gukoreshwa tutongeye gukanda.
Kurwanya Ubushyuhe buhebuje: Igumana ubunyangamugayo bwo kurinda kugeza kuri 300 ° C, iruta kure cyane ibisanzwe bya zinc bitesha agaciro hejuru ya 100-200 ° C.
Ikirere kidasanzwe no kurwanya imiti: Irwanya ikirere cyinganda, umunyu wumuhanda, acide yoroheje na alkalis mugihe utanga igihe kirekire Kurwanya ingeseimikorere hanze.
Igenzura ryiza: Hamwe n'amavuta yo kwisiga atabishaka, coefficient de friction irashobora kugenzurwa cyane kugirango umutwaro wizewe.

4. Kugereranya imikorere hamwe na Gakondo gakondo

Imbonerahamwe ikurikira irerekana muri make itandukaniro ryingenzi muri kurinda ruswa n'ibiranga.

Umutungo	Dacromet	Amashanyarazi	Bishyushye
Ubunini	5-12 mm	5-15 mm	40-80 mm
Gusiga umunyu (nta ngese itukura)	≥1,000–1,200 h	100-300 h	500-800 h

Kurwanya Ubushyuhe	Kugera kuri 300 ° C.	≤100 ° C.	≤200 ° C.
Ingingo Ihuza Ingaruka	Ntarengwa / byiza	Buhoro	Akenshi bisaba kongera gukanda

Imbonerahamwe 1. Kugereranya imikorere ya Dacromet hamwe na zinc zisanzwe zifatika.

5. Porogaramu zisanzwe

Dacromet flange bolts igaragara ahantu hose hejuru Kurwanya ruswa bigomba guhuzwa no kwizerwa kwa mashini:

Imodoka: Chassis, guhagarikwa, sisitemu ya feri hamwe nibice bigize umunyu wo mumuhanda.
Ingufu z'umuyaga & offshore: Umunara wa flanges, inteko za nacelle hamwe nubusabane bwubatswe mukirere cyumunyu.
Construction & infrastructure: Ikiraro, inyubako zo ku nkombe, izamu risaba igihe kirekire kwirinda ingese.
Imashini ziremereye & gari ya moshi: Ibikoresho mubushuhe cyangwa imiti yibasiye aho kurwanya ruswaimikorere ni ngombwa.

6. Ibisobanuro rusange

Dacromet flange bolts ikorwa mubipimo mpuzamahanga byingenzi hamwe n amanota yimbaraga:

Parameter	Urwego rusanzwe / Indangagaciro
Ibipimo	DIN 6921, ISO 4162, GB / T 5787/5789, ASME B18.2.1

7. Kwishyiriraho imyitozo myiza & Umwanzuro

Kugwiza i kurwanya ruswa ubuzima bwa serivisi ya Dacromet flange bolts: koresha guhuza Dacromet yuzuye utubuto hamwe nogeshe aho bishoboka; gukurikiza indangagaciro za torque (kugenzurwa gushigikira gushyigikira umutwaro wuzuye); irinde kwangirika gukabije mu gihe cyo gukemura; kandi ubike ibifunga mubihe byumye mbere yo gukoresha.

Muncamake, Dacromet flange bolts yerekana igisubizo gikuze, cyihuse-cyihuse cyo gukemura gikemura neza ibisabwa bibiri byokwizerwa kandi birebire kurinda ruswa. Muguhuza ibyiza-byo kugabura imitwaro yuburyo bwa flange igishushanyo mbonera, cyoroshye cyane cya zinc-aluminium flake, ibyo bifunga bitanga ibintu byiza Kurwanya ingese imikorere, ikureho hydrogène ishobora kwanduza, kandi ukomeze kugenzura neza.

Mubidukikije aho amashanyarazi asanzwe ya elegitoronike cyangwa ashyushye-ashyushye yomekaho igihe kitaragera ingese no gutesha agaciro-inkombe, inyanja, ibinyabiziga, ninganda-Dacromet flange bolts itanga ubundi buryo bwagaragaye, burambye. Nibyiza cyane ikirere, Kurwanya okiside, na kurinda ibitambo uburyo butuma serivisi ziyongera kandi zikagabanya amafaranga yo kubungabunga, bigatuma bahitamo cyane kubashakashatsi n'abashushanya isi yose.
