Urabona iki kibazo kigaragara muri spes na RFQs igihe cyose. Igisubizo kigufi, kigerageza akenshi ni yego, ni zinc-yuzuye, nibyiza. Ariko niba warabaye kurubuga ureba imyaka yimiterere, cyangwa birushijeho kuba bibi, ukemura ikibazo cyo guhamagarwa kumurongo watsinzwe, uziko bidakunze kuba byoroshye. Igisubizo nyacyo kibaho muburyo burambuye bwibidukikije, ubwiza bwamasahani, kandi mvugishije ukuri, icyo kuramba bivuze mubyukuri mubuzima bwumushinga ugereranije no kuba icyatsi kibisi. Reka dukureho ibyo.

Allure nukuri kwukuri kwa Zinc

Electro-galvanizing irashimishije kubwimpamvu. Mubisanzwe birahenze cyane kuruta gushyushya-gushiramo kandi bigatanga isuku, yoroshye isa neza neza neza mumasanduku. Inzira ikubiyemo amashanyarazi ya zinc kumurongo wibyuma. Ibipimo by'ingenzi buri wese aterera hirya no hino ni ugutwikiriza ubunini, akenshi bigamije kugera kuri microne zigera kuri 5-8 kuri elegitoroniki isanzwe. Uru rupapuro rutanga kurinda inzitizi. Irinda ibyuma kumubiri nubushuhe.

Ariko dore hiccup yambere ifatika: icyo gipimo ni gito. Kandi ntabwo ihujwe nicyuma nko muri hot-dip. Nabonye ibyiciro aho igipfundikizo kitaringaniye, cyane cyane mumutwe no munsi yumutwe - ahantu nyine guhangayika. Utanga isoko ashobora gusaba guhuza na ASTM B633, vuga, SC Ubwoko bwa 2, ariko udafite igenzura rihoraho, ubona ibibanza bidakomeye. Isosiyete nka Hamagara zitai yihuta ukora co., Ltd., ishingiye ku isoko rikuru ry’ibicuruzwa byihuta mu Bushinwa i Yongnian, Hebei, ryaba rifite ubushobozi bwo gukora ibintu byinshi, ariko inshingano iri ku baguzi kugira ngo barebe niba ireme ry’ibicuruzwa biva hanze, atari ukubitekereza gusa.

Noneho, kubusitani bwubatswe mubihe byumye? Birashoboka ko ari byiza kumyaka. Kuri gariyamoshi ya balkoni yinyanja, ibikoresho byikiraro mukarere k’imvura, cyangwa inyubako iyo ari yo yose ifite uruziga rwumye? Iyo nzitizi yoroheje, ishobora kuba idatunganye ihinduka ihuriro ridakomeye. Ikirego kirambye gitangira gucika mugihe ibicuruzwa bikeneye gusimburwa mumyaka 5.

Uburyo bwo kwangirika: Ntabwo ari ingese gusa

Abantu batekereza hanze no gushushanya ingese. Ukuri kuribanze kandi ni mubi. Ibice bibiri nyamukuru byica amashanyarazi ya elegitoronike hanze ni ingese yera na ruswa ya galvanic.

Ingese yera niyo powdery kubitsa byera ubona kuri zinc. Bibaho mugihe igifuniko cya zinc gihora gitose kandi ntigishobora gukora patina yacyo ikingira (karubone ya zinc). Ahantu hihishe hanze aho amazi yicaye-nko hagati yubuso bufunze cyangwa mumyobo ya bolt idafite amazi-zinc irabora ibitambo kandi vuba. Nakuyeho guhuza nyuma yibihe bibiri kugirango nsange zinc ahanini ihinduka ifu yera, hasigara ibyuma hafi.

Ruswa ya Galvanic numwicanyi ucecetse. Hindura amashanyarazi ya electro-galvanis hamwe na aluminiyumu, cyangwa birushijeho kuba bibi, umuringa cyangwa ibyuma bidafite ingese, imbere ya electrolyte (amazi y'imvura arahagije), hanyuma ugakora bateri. Zinc, kuba anodic, yangirika vuba kugirango irinde ibindi byuma. Ndibuka umushinga ukoresha electro-sulvanize kurinda umutekano wumuringa. Icyerekezo cyihuse. Mugihe cyamezi 18, imitwe ya bolt yapfushije ubusa, ibangamira gukosorwa. Gukosora byari gusimburwa byuzuye, bihenze hamwe nibyuma bidafite ingese. Kuzigama kwambere byavanyweho.

Kwambika Ubunyangamugayo n'ikibazo cyinsanganyamatsiko

Ingingo yububabare yihariye ni insanganyamatsiko. Inzira ya electroplating irashobora gusiga igicucu, cyubatswe hejuru hejuru yumutwe. Mugihe cyo kwishyiriraho, iyi coating irashobora gukata cyangwa kuzimya. Noneho ufite impungenge ziterwa no kurinda ruswa. Twatangiye kwerekana chromate ihinduranya (iridite yumuhondo cyangwa ubururu busobanutse) kuri bolts ya electro-galvanised kugirango irinde gato, ariko nubwo aribwo buryo bwa passivation gusa kuri zinc, ntabwo ari ugukosora ibyangiritse. Kumanura hejuru ya bolt birashobora kuyikuraho hejuru yumutiba cyangwa umwobo wafashwe.

Ikiburanwa: Umushinga Uruzitiro Ruto-Igiciro

Urugero rufatika kuva mumyaka mike ishize. Parike ya komine yashakaga gushyiraho metero amagana y'uruzitiro rw'ibyuma. Ingengo yimari yari mike. Ikirangantego cyahamagaye ibisumizi. Rwiyemezamirimo, agamije gupiganira isoko rito, yashakishije amashanyarazi ahendutse ya electro-galvanised, bishoboka ko yaturutse ku bicuruzwa byinshi. Basaga neza cyane mugushiraho.

Ihute mbere yimyaka itatu, mukarere gafite ikirere giciriritse cyinganda hamwe no gutera umunyu mumuhanda mugihe cy'itumba. Uruzitiro rwuruzitiro rwari rwiza (hot-dip galvanised), ariko buri mutwe wa bolt numutobe byari akajagari k'ingese zitukura hamwe nigitaka cyera. Ruswa yari mbi cyane kuburyo hafashwe imbuto zimwe, bisaba gusya inguni kugirango ziveho muri retrofit. Iterambere rirambye ryari zeru - guta akazi kenshi nibikoresho byo gusana imburagihe. Iyaba icyerekezo cyasabye mu buryo bweruye ibyuma bifata ibyuma bishyushye (HDG) kugirango bihuze umwenda w'uruzitiro, cyangwa birushijeho kuba byiza, gukanika imashini kugirango bifatanye neza, ubuzima bwaba bwikubye kabiri cyangwa gatatu.

Aha niho gushakisha amakuru bifite akamaro. Aho uruganda ruherereye, nka Zitai Fastener yegeranye ninzira nini zo gutwara abantu (Gari ya moshi ya Beijing-Guangzhou, Expressway), ivuga imikorere yibikoresho, ntabwo ibereye ibicuruzwa. Ugomba gucukumbura uburyo bwihariye bugenzura kubikorwa byo hanze-electro-galvanizing, niba ndetse bayitanga nkumurongo wabigenewe.

Iyo Birashoboka ko Electro-Galvanised Akazi Hanze?

Ntabwo ari ibyago byose. Hano hari ibibanza. Ihamagarwa ry'urubanza riva ku buremere bw’ibidukikije no kugerwaho no kubungabunga.

Imbere cyangwa yuzuye hanze yimikorere yo hanze (nko muri sisitemu yumuyaga ya truss ihumeka irinzwe nikirere gitaziguye), amashanyarazi arahagije rwose. Kurwanya ruswa birahagije kurwanya ubushuhe bwikirere bwonyine.

Ikindi kintu ni icyerekezo cyo hanze cyagenewe gusenywa no kongera gukoresha mugihe gito, vuga imyaka 1-3. Kurangiza neza bituma gukora byoroshye. Na none, niba icyuma kigiye gusiga irangi cyangwa gusiga ifu nkigice cyiteraniro, igikoresho cya electro-galvanised gitanga urufunguzo rwiza, rusukuye kuri sisitemu yo gusiga amarangi kandi ikongeramo urwego rwuburinzi. Ariko sisitemu yo gusiga irangi igomba kuba idahwitse kandi igashyirwa mubikorwa neza - gushushanya mugihe cyo kwishyiriraho cyangwa serivisi bizashiraho ingingo yibanda kuri ruswa.

Icyemezo: Kuramba ni Imikorere Yubuzima

Noneho, subira kubibazo byibanze. Ese amashanyarazi ya elegitoronike arashobora gukoreshwa hanze? Ibyo mfata, kuva kurwana naya mahitamo inshuro nyinshi, nibi: birashoboka, ariko gusa mugihe gito cyane cyibintu bidakunze kuboneka muburyo rusange bwo hanze.

Kuramba kwukuri bisobanura guhitamo ibikoresho bikwiye kubuzima bwa serivisi buteganijwe hamwe nibidukikije kugirango wirinde gutsindwa imburagihe no gusimburwa. Kubintu byinshi bisabwa hanze - inyanja, ubuhehere bwinshi, inganda, de-icing yumunyu, cyangwa ibyubaka bihoraho - ibyuma bisanzwe bya elegitoronike ni amahitamo menshi. Amahitamo arambye arashyushye cyane, ashizwemo imashini, cyangwa ibyuma bidafite ingese (nka 304 cyangwa 316, bitewe na chloride). Igiciro cyabo cyo hejuru cyambere cyahinduwe mugihe kirekire cyane, ubuzima bwa serivisi butarangwamo serivisi.

Igitekerezo cya nyuma: burigihe ugaragaze neza. Ntukandike gusa galvanised. Kugaragaza inzira (urugero, ASTM A153 ya hot-dip), uburebure bwa coating, hamwe nubuvuzi ubwo aribwo bwose. Kandi kubice bikomeye, tekereza kugenzura aho icyiciro cya mbere cyiziritse. Ikizamini cyihuta cyumunyu kuri ASTM B117, niyo yagenzura amasaha 96 gusa, irashobora guhishura byinshi kubyerekeranye nubwiza bwabatanga nibisabwa na catalog. Ikiza isi yububabare bwumutwe nyuma, ihindura imyumvire irambye yibikorwa bifatika, kubutaka.
