Dacromet Hexagonal Bolts-Intangiriro Yuzuye Kumikorere Yinshi-Ruswa-Kurwanya-Kwizirika 

2. Gutwika Dacromet ni iki?

Dacromet ni sisitemu yo gutwikisha ibintu idasanzwe igizwe na ultrake nziza ya zinc flake, ifu ya aluminium, hamwe na chromium ishingiye (cyangwa idafite chromium). Ikoreshwa nk'amazi asakaye kandi igakira hafi ya 300 ° C, ikora amorphous binder ihuza ibyuma byuzuzanya muri firime ikingira. Ubunini busanzwe butwikiriye ni 4-8 mm gusa - biroroshye cyane kuruta gushiramo imbaraga (50-80 mm) - nyamara bitanga uburinzi bukabije. Ubuso bwuzuye bufite ifeza-imvi imwe isa.

Ibyingenzi: zinc flake (60-80%) mukurinda ibitambo, ifu ya aluminiyumu (5-15%) kubintu byongerewe imbaraga za barrière, umuhuza wa organic organique unyura hejuru yubutaka, hamwe namazi ya deionion nkuburyo bwo gutwara.

3. Ibyiza byingenzi bya Dacromet Hexagonal Bolts

3.1 Kurwanya ruswa idasanzwe

Ububiko bwa Dacromet ya 4-8 mubisanzwe birwanya amasaha arenga 1.000-1200 yo gupima umunyu utabogamye (ASTM B117) udafite ingese itukura - hafi inshuro 7 kugeza ku 10 imikorere ya electro-galvanizing (amasaha 100-300). Impamyabumenyi-yo hejuru irashobora kurenza amasaha 2000. Imiterere ya flake yibice byinshi ikora nkinzitizi yumubiri hamwe na anode yigitambo, itanga uburinzi bwigihe kirekire mubidukikije, ku nganda, no mumihanda-umunyu.

3.2 Umudendezo wo Kwinjiza Hydrogene

Gukoresha amashanyarazi gakondo birimo gutoranya aside hamwe na electrolysis, bishobora kwinjiza hydrogène mubyuma bikomeye kandi bigatera kuvunika gutinda-cyane cyane mubyiciro 10.9 na 12.9. Inzira ya Dacromet ikoresha gusa isuku yubukanishi hamwe nogukoresha amashanyarazi, bikuraho burundu ibyago byo kwinjiza hydrogène. Ibi bituma ibifuniko byatoranijwe kuburinzi-bukomeye-buringaniye buringaniye.

3.3 Kurwanya Ubushyuhe budasanzwe

Ipfunyika ya Dacromet ikomeza kuba nziza kandi ikingira ubushyuhe bukomeza bugera kuri 300 ° C. Ibisanzwe bya zinc bitangira kugabanuka hejuru ya 70-100 ° C kandi birashobora gukuramo 200-300 ° C. Ihindagurika ryumuriro rituma Dacromet ihinduranya impande esheshatu nziza kubice bya moteri, sisitemu yo kuzimya, hamwe nubushyuhe bwo hejuru bwinganda.

3.4 Ibipimo bihamye hamwe nu murongo uhuza

Ipfunyika ya ultra-thin, ihuza ntabwo ihindura cyane ibipimo byurudodo cyangwa diameter. Imbuto ziteranya neza nta gukanda gukabije akenshi bisabwa nyuma yo gushyuha. Ipfunyika kandi yinjira mu mwobo wimbitse, mu mwobo, no hejuru yimbere amashanyarazi adashobora kurinda byimazeyo. Byongeye kandi, firime ihuza neza na substrate kandi ikemera ibinyabuzima byakurikiranye cyangwa amarangi hamwe no gufatana neza.

4. Uburyo bwo gukora no gutwikira

Hexagonal bolts ikorwa mubyuma biciriritse cyangwa ibyuma bivangwa nicyuma gikonje cyangwa guhimba bishyushye, bigakurikirwa no kuzunguruka no kuvura ubushyuhe kugirango ugere kumurongo ukenewe (mubisanzwe 8.8, 10.9, cyangwa 12.9). Nyuma yo gukora isuku neza, igifuniko cya Dacromet gikoreshwa kuburyo bukurikira:

1.Itegurwa ry'ubutaka: Kugabanuka kwa alkaline hamwe no gukanika imashini (nta gufata aside).

2.Gusaba porogaramu: Kwibiza kwibiza kubintu byinshi cyangwa gutera ibice binini; gutwikira birenze byavanyweho na centrifugation.

3.Gukiza: Guteka hafi 300-320 ° C muminota 15-30 kugirango ukore flake ikingira.

4.Ikoti ryemewe: Ikidodo cyangwa amavuta birashobora gukoreshwa kugirango byongere ruswa kandi bigenzure coefficient de frais.

5. Porogaramu zisanzwe

Dacromet ya mpande esheshatu zirasobanuwe neza aho kwizerwa kuramba mugihe cyangirika cyangwa ubushyuhe bwo hejuru ni ngombwa:

Imodoka: Chassis, guhagarikwa, sisitemu ya feri, ibyuma bigizwe na moteri, hamwe nibice byerekana umunyu wo mumuhanda.

Ingufu z'umuyaga & amashanyarazi: Umunara wubatswe hamwe nudukingirizo twubatswe kuruhande rwumuyaga wumuyaga.

Marine & offshore: Ibyuma byububiko hamwe nuburyo bwa platform byerekanwe kumasoko yumunyu wamazi.

Construction & infrastructure: Guhuza ibyuma, ibice byikiraro, hamwe nuburyo bwo hanze bwubatswe.

Gari ya moshi, imashini ziremereye, icyogajuru & defence: Ingingo zikomeye zifatika ziterwa no kunyeganyega, ikirere, hamwe no guhangayika.

6. Kugereranya na Coatings gakondo

Ibikorwa byingenzi bitandukanye byerekana impamvu Dacromet ikundwa kumikorere-ya mpande esheshatu:

Umubyimba wuzuye: Dacromet 4-8 μm |  Amashanyarazi-5-5 μm |  Gushyushya-gushiramo 50-80 mm

Kurwanya umunyu (nta ngese itukura): Dacromet ≥1,200 h |  Amashanyarazi 100-300 h |  Gushyushya-500-800 h

Impanuka ya hydrogène: Dacromet - Ntayo |  Gukoresha amashanyarazi - Hejuru |  Bishyushye - Hagati

Kurwanya ubushyuhe bwo hejuru: Dacromet igera kuri 300 ° C |  Amashanyarazi -100 ° C |  Gushyushya -200 ° C.

Ingingo ikwiye: Dacromet ikomeza kwihanganira neza; hot-dip galvanizing akenshi bisaba indishyi.

7. Ibipimo, amanota, nibisobanuro

Bolt ya Dacromet itandatu ikozwe mubipimo mpuzamahanga harimo ISO 4014/4017, DIN 931/933, ANSI / ASME B18.2.1, na GB / T 5782/5783. Ibyiciro byumutungo rusange ni 4.8, 8.8, 10.9, na 12.9 (metric) cyangwa icyiciro cya 5 nicyiciro cya 8 (santimetero). Ibikoresho birimo ibyuma bya karubone hamwe nibyuma nka 35CrMo, 40Cr, na 42CrMo. Ingano isanzwe ni M5 kugeza M36 (ingano nini iboneka kubisanzwe bidasanzwe), mumurongo-wuzuye cyangwa igice-cy-ibice. Imodoka nyinshi za OEM urutonde Dacromet cyangwa ibingana na zinc-flake nkuko byemejwe birangirira imbaraga zikomeye.

8. Ibidukikije

Gakondo ya Dacromet ikubiyemo chromium ya hexavalent muri binder. Mugihe igifuniko cyakize gihamye kandi inzira ikabyara amazi mabi cyane kuruta amashanyarazi, amabwiriza y’ibidukikije yatumye habaho iterambere ry’ubundi buryo butagira chromium nka Geomet® hamwe n’ubundi buryo bugezweho bwa zinc-flake. Ibi bigumana ibyiza byibanze bya Dacromet mugihe byujuje ibisabwa RoHS hamwe na REACH ibisabwa.

Muri rusange, inzira ya Dacromet ifatwa nkibidukikije cyane kuruta amashanyarazi asanzwe kuko ikuraho ubwogero bwa aside, ibisubizo bya cyanide, hamwe no gutunganya amazi mabi. Ubuhanga bwa chimie bushingiye kumazi nabwo butera imyuka ihumanya ikirere (VOC).

9. Umwanzuro

Dacromet ya mpande esheshatu zitanga igisubizo-cyiza cyibisubizo bisaba kwizerwa no gukingira igihe kirekire. Guhuza kwabo gukomeye cyane ariko gukomeye cyane, ubwisanzure bwuzuye bwo kwinjiza hydrogène, kurwanya ubushyuhe buhebuje, no kugenzura neza ibipimo bituma biba iby'igiciro cyinshi kubifata imbaraga nyinshi mumashanyarazi, ingufu, inyanja, nubwubatsi.

Mugihe amabwiriza y’ibidukikije agenda atera imbere, chromium idafite zinc-flake yambarwa ikomoka ku buhanga bwa mbere bwa Dacromet ikomeje kwagura uburyo bwo guhitamo. Byaba bisobanuwe nka Dacromet ya kera cyangwa ibisa nayo igezweho, ibyo biti bitwikiriye impande esheshatu bitanga igihe kirekire byerekana igihe kirekire kandi bikagabanya amafaranga yo kubungabunga ibidukikije byangirika kandi bifite ubushyuhe bwinshi. Kubintu bikomeye aho kunanirwa atari amahitamo, Dacromet ya mpande esheshatu ikomeza kuba imwe mubisubizo byizewe kandi byikoranabuhanga byihuta byihuse biboneka uyumunsi.
