Amabara ya zinc yashizwemo amabara: guhanga udushya? 

Urabona 'amabara ya zinc yashizwemo amabara' kurupapuro rwihariye cyangwa kurubuga rwabatanga isoko, kandi reaction ihita mumurongo wakazi yacu akenshi iba ivanze no gushidikanya namatsiko. Nuburyo bwo kwamamaza gusa, uburyo bwo kwishyuza byinshi kumashanyarazi asanzwe afite irangi ryirangi? Cyangwa hari impaka zukuri zubushakashatsi nibidukikije zashyinguwe munsi yurwo rwego rwa pigment? Njye namaze imyaka nshakisha kandi ngerageza kwizirika kubikorwa bitandukanye byo hanze no mubwubatsi, kandi ndashobora kukubwira, ikiganiro kijyanye nibi bice ni gake cyane umukara n'umweru - cyangwa muriki gihe, ifeza nubururu. Ikirego kirambye nicyo gifatika nyacyo, ariko cyahujwe nimpimbano yimikorere, shitingi ya chimie, hamwe nibintu bikaze bivuye hasi muruganda.

Kurenga Ubwiza: Imikorere nyayo yamabara

Reka tugabanye imyumvire ya mbere yibeshya: ibara ntabwo ahanini rigaragara. Nukuri, yemerera amabara-code muguterana cyangwa guhuza inyubako, ifite agaciro. Ariko muburyo bukora, iyo koti yamabara-mubisanzwe ihinduranya chromate isize irangi cyangwa kashe kama-nakazi keza. Isahani isanzwe isobanutse cyangwa yubururu-yuzuye ya zinc itanga uburinzi bwo kwangirika, ariko igihe cyayo cyo kurwanya ingese yera, cyane cyane ahantu h’ubushuhe cyangwa ku nkombe, birashobora kuba bigufi. Igice cyamabara, akenshi kibyibushye cyane cyangwa kitari hexavalent chromate layer, ikora nkinzitizi ikomeye cyane. Ifunga ikariso ya zinc munsi. Nabonye ibice bisanzwe bya zinc bivuye mubice byerekana kwangirika kwera nyuma yamasaha 48 mugupimisha umunyu, mugihe iridescent yumuhondo kuva murwego rumwe yari ikiri isuku mumasaha 96. Itandukaniro ntabwo ryisiga; ni kuzamura shingiro mukurwanya ruswa.

Ibi biganisha muburyo butaziguye. Niba bolt imara inshuro ebyiri cyangwa eshatu mbere yo kwangirika, urimo kugabanya inshuro zisimburwa, imyanda yibikoresho, hamwe nakazi / imbaraga zo kubungabunga. Iyo ni inyungu ifatika yubuzima. Ariko-kandi ni binini ariko-ibi bishingiye rwose ku busugire bwurwo rugendo rwamabara. Kwiyuhagira kugenzurwa nabi, igihe cyo kwibiza kidahuye, cyangwa kwoza bidahagije birashobora kugusiga igice gisa nkicyiza uhageze ariko bikananirana imburagihe. Ibara rishobora guhisha ibyaha byinshi murwego rwibanze rwa zinc, niyo mpamvu kwiringira kugenzura ibikorwa byawe bitaganira.

Ndibuka umushinga wa gari ya moshi yo ku nyanja. Umwubatsi yashakaga umuringa wijimye wihariye. Twashakishije amabara ya zinc bihuye neza. Biboneka ko bari batagira inenge. Mu mezi 18, twagize raporo zerekana ingese. Isesengura rya nyuma yo gutsindwa ryerekanaga urwego rwa zinc rworoshye kandi ruto; ikoti nziza nziza yari yipfutse gusa akazi keza ka plaque. Ibicuruzwa biramba, biramba byabaye isoko yo kunanirwa imburagihe no guta. Isomo ntabwo ryari uko ikoranabuhanga ari ribi, ariko ko imikorere yaryo iterwa rwose nibikorwa.

Guhindura Chimie: Kuva Hex-Cr Kuri Trivalent na Hanze

Igikoresho cyo kuramba cyahinduye muburyo bwa chimie inyuma yiyi myenda. Mu myaka ibarirwa muri za mirongo, igipimo cya zahabu cyo kurwanya ruswa cyane ni chromate ya hexavalent (Hex-Cr) passivation layer. Yabyaye ibyo biranga umuhondo cyangwa iridescent birangira kandi byari byiza cyane. Ariko kandi ni uburozi cyane na kanseri, biganisha ku mategeko akomeye y’ibidukikije n’abakozi (RoHS, REACH). Kwita Hex-Cr yatwikiriwe na bolt birambye byaba bisekeje, utitaye kuramba.

Guhanga udushya-intambwe nyayo irambye-yabaye iterambere rya chromate trivalent trivalent na chromium (urugero, zirconium, ishingiye kuri silika) impuzu zishobora guhinduka amabara. Ibi ntibishobora guteza akaga. Iyo utanga isoko nka Hamagara zitai yihuta ukora co., Ltd. ivuga kubyerekeranye na plaque ya zinc ibara ubungubu, rwose baravuga kuri chimisties nshya. Iherereye muri Yongnian, umutima w’umusaruro wihuse w’Ubushinwa, bari mu karere kagomba guhuza byihuse n’ibipimo by’ibidukikije ku isi. Guhindura ntabwo byemewe kubohereza ibicuruzwa hanze.

Ariko, impaka zingirakamaro impaka nukuri. Chromates yambere itajyanye na Hex-Cr yo kwikiza cyangwa kurwanya umunyu. Ikoranabuhanga ryafashe ku buryo bugaragara, ariko risaba kugenzura neza inzira. Chimie yo kwiyuhagira ntishobora kubabarira. Nagize reps tekinike yo gutwikisha uruganda rukora imiti yemera ko niba pH cyangwa ubushyuhe bugenda bugabanuka, guhuza ibara hamwe no kwangirika kwimikorere yibintu bitatu birashobora gutandukana kurenza ibya kera, uburozi. Noneho, ubundi buryo burambye busaba ubuhanga buhanitse kubukora. Ntabwo byoroshye guta-gusimburwa.

Tanga Urunigi Ukuri hamwe na Yongnian Factor

Iyo ucukuye hasi aho ibi amabara ya zinc biva, ingano nini inyura mumatsinda nkakarere ka Yongnian muri Handan. Kwibanda kubuhanga nibikorwa remezo biratangaje. Isosiyete nka Handan Zitai Fastener, ihagaze hafi yinzira nini zitwara abantu, ikubiyemo igipimo nubushobozi bwiki kigo. Bashobora gukora urunigi rwose: umutwe ukonje, urudodo, kuvura ubushyuhe, isahani, hamwe namabara. Uku guhuza guhagaritse nurufunguzo rwo kugenzura ubuziranenge mubikorwa byoroshye nkibisahani byamabara.

Ariko igipimo kizana ibibazo byacyo. Mugihe gikenewe cyane, Nabonye ubuziranenge buhoraho bubabaza akarere kose. Icyiciro cyamabara, akenshi intambwe yanyuma, irashobora guhinduka icyuho. Kwoza neza cyangwa kugabanya igihe cyo kumisha mbere yo gupakira birashobora gutuma habaho kubika amazi - kwangirika kugaragara muri transit kuko ubuhehere busigaye bufashwe na bolt. Wakiriye agasanduku k'amabara meza afite amabara atangiye guhinduka ingese zera mumirongo. Ibi ntabwo ari kunanirwa kw'igicuruzwa, ahubwo ni ibikoresho byo gutanga umusaruro n'amarembo meza. Nibyibutsa bifatika ko kuramba bitajyanye na chimie ya coating gusa; bijyanye na disipuline yose yo gukora ikumira imyanda.

Urubuga rwabo, zitiFasTeners.com, yerekana intera-kuva mubisanzwe galvanised to Ibara rya Zinc amahitamo. Ibyo utabona ni ishoramari ryihishe inyuma yo gutunganya amazi mabi kumirongo yabo ya plaque, kikaba ari igice kinini cyibiciro nyabyo byibidukikije. Ubwitange bwumutanga mugutunganya imyanda iva muburyo bwo gusiga no gusiga amabara, uko mbibona, ni ikimenyetso cyerekana imyifatire yabo irambye kuruta ibara rya bolt ubwayo.

Gusaba Ibisobanuro byihariye: Aho Bituma Byumvikana (n'aho Bitabikora)

None, ni ryari ugaragaza amabara ya zinc-yashizwemo? Ntabwo ari ukuzamura isi yose. Kubidukikije, byumye, birakabije; zinc isanzwe irahenze cyane. Ikibanza kiryoshye kiri mubikorwa byo hanze aho hakenewe kurwanya ruswa iringaniye kandi ndende, ariko ibyuma bidafite ingese birabuza ikiguzi, kandi gushyushya-gushya ni binini cyane cyangwa bikabije kubiterane. Tekereza uruzitiro rw'amashanyarazi, gushiraho HVAC, gushiraho imirasire y'izuba, ibikoresho byo gukiniraho, hamwe nibyuma byububiko.

Twabikoresheje neza kurukurikirane rwa modular yo hanze yo kumurika. Bolt yari ikeneye kuvanga hamwe numuringa wijimye wijimye no kwihanganira ikirere cyumujyi. Ibara ryibara rya chromate bolts ryatanze ruswa irwanya ruswa hamwe nuburanga bwiza. Imyaka itanu muri, nta kubungabunga, baracyareba kandi bakora neza. Iyo niyo ntsinzi yo kuramba-nta gusimburwa, nta kizinga, nta guhamagarwa.

Ariko hariho imipaka. Twagerageje kubikoresha muburyo bukabije, bwinyeganyeza cyane kumashini zubuhinzi. Ipitingi y'amabara, nubwo irwanya ruswa, yari yoroheje kandi yambaraga vuba mugihe cyo hejuru, byerekana zinc iri munsi kwambara vuba. Kunanirwa. Yatwigishije ko kurwanya abrasion ari umutungo utandukanye rwose. Udushya twihariye; ikemura ikibazo cyo kwangirika / kumenyekanisha, ntabwo kwambara imashini.

Icyemezo: Yego Yujuje ibisabwa, Amaso Yuguruye

Nibintu bishya birambye? Nibyo, ariko hamwe nubushobozi buremereye. Kwimuka uva muburozi Hex-Cr ujya mumiti ya chimisties itagira ingano cyangwa idafite chrome ni intsinzi yibidukikije nubuzima. Ubushobozi bwo kongera ubuzima bwa serivisi binyuze murwego rwo hejuru kurinda inzitizi bigabanya imyanda. Ngiyo ishingiro ryurubanza rurambye.

Nyamara, ijambo rirambye rigenda ryoroha niba inzira yo gukora isesagura cyangwa igenzurwa nabi, biganisha ku gipimo cyo kwangwa cyane cyangwa kunanirwa imburagihe mu murima. Agashya ntabwo kari muri bolt kuba ubururu cyangwa umuhondo; ni muri chimie yateye imbere, igenzurwa ikoreshwa neza neza hejuru yijwi rya zinc substrate. Irasaba uwabikoze ubishoboye, ushora imari.

Inama nakugira? Ntugategeke gusa ukoresheje ibara. Baza inzira. Baza raporo yikizamini cya spray yumunyu (ASTM B117) yerekana amasaha kugeza ingese yera numutuku kugirango irangire ryamabara yihariye. Baza ibijyanye no gucunga amazi mabi. Kugenzura niba ubishoboye. Kuramba kwukuri, nibikorwa, biva muburyo burambuye inyuma yamabara. Kubatanga ibicuruzwa bakora murwego rwo kugenzura hamwe, kimwe nabari muri Yongnian base bamenyereye, byerekana intambwe yateye imbere. Kubandi, ni ibyuma byamabara gusa. Kumenya itandukaniro nibintu byose.
