Hot-dip galvanised bolts: birambye kubinganda? 

Urumva 'hot-dip galvanised' ukibwira ko 'idashobora kurimburwa, irambye, kujya-kurangiza.' Ariko iyo niyo nkuru yose hasi? Mumaze gushakisha no gutondekanya ibi mumyaka, nabonye itandukaniro riri hagati yamasezerano ya kataloge nukuri kuri convoyeur yinyeganyeza cyangwa mukibuga cyinyanja. Ikibazo kirambye ntabwo kireba zinc gusa; byerekeranye nubuzima bwose, kuva ikigega cyo gutoragura kugeza amaherezo azasimburwa. Reka tugabanye ibicuruzwa byo kwamamaza.

Inkinzo ya Zinc: Kurenza Igipfukisho

Icya mbere, reka tubyumve neza: hot-dip galvanizing (HDG) itanga uburinzi buhebuje bwo kwangirika binyuze mumurongo wa metallurgical hamwe nigikorwa cya anode. Icyo ni igitabo. Ariko kuramba kwukuri guterwa cyane nubwiza bwibanze bwibyuma no kugenzura inzira. Nabonye bolts kuva mubyiciro bizwi birananirana imburagihe kuko ibyuma byimbere byari bifite umwanda utera gufatana kuringaniza. Zinc yakoze akazi kayo, ariko yarwanaga nintambara kuva ku rufatiro rudakomeye. Ntabwo ari ugushira gusa; bijyanye nibyo urimo kwibiza.

Noneho hariho inzira ubwayo. Igikorwa gikwiye cya HDG gikubiyemo gutegura cyane-kugabanuka, gutonyanga, gutemba. Niba aside irike idacunzwe neza, ubona hydrogène yo kwinjiza, cyane cyane kumashanyarazi akomeye. Ndibuka umushinga aho twagize urukurikirane rwibipimo 8.8 bya bolts snap munsi ya tension. Intandaro? Guteka bidahagije nyuma yo gusya kugirango wirukane hydrogen. Ikirego kirambye kiratandukana niba ibice byananiranye muburyo mbere yuko ruswa ibona amahirwe.

Kandi kurangiza ntabwo ari kimwe no kwisiga. Ubona ibitonyanga, biruka, hamwe nibiranga spangle. Kubikorwa bimwe byubaka, nibyiza. Ariko kubiterane byuzuye aho kwihanganira ibipimo bigoye, ubwo bunini bwinyongera kumutwe burashobora kuba inzozi. Ukeneye kenshi gusubiramo ibinyomoro cyangwa gukoresha gukanda cyane, byongera ikiguzi kandi gikomeye. Guhitamo 'kuramba' ntabwo kuramba cyane niba kurema imyanda no kongera gukora hepfo.

Gupima Ibidukikije

Iyo abantu bavuga kuramba, akenshi batekereza kuramba. Ariko ikiguzi cyibidukikije cyumusaruro nigice kinini cyikigereranyo. Inzira ya HDG ikoresha ingufu nyinshi - gushyushya indobo nini za zinc kugeza kuri 450 ° C. Zinc ubwayo ni ibikoresho. Mugihe gishobora gukoreshwa, umusaruro wibanze ufite ikirenge cyacyo. Icyiciro cyo gutoranya gikoresha hydrochloric cyangwa acide sulfurike, bigakora imyanda ikenera kutabogama no kuyijugunya. Isuzuma rirambye rwose rigomba kubarwa.

Gereranya na plaque ya mashini cyangwa shyashya, yoroheje ya firime inorganic. Bashobora kuba bafite umutwaro wambere wibidukikije, ariko niba bakeneye gusimburwa inshuro ebyiri, urareba ibintu byinshi byinganda, ubwikorezi bwinshi, imirimo myinshi yo kwishyiriraho. Kubijyanye ninganda cyangwa ibikorwa remezo biremereye - tekereza iminara yohereza amashanyarazi, izamu ryumuhanda - intera ndende ya HDG ikomeza gutsindira isuzuma ryubuzima. Nubucuruzi-buke: ingaruka zambere imbere hamwe nigihe kirekire.

Nakoranye nuwahimbye uruganda rutunganya amazi mabi. Babanje gutekereza ibyuma bifata ibyuma bitagira umuyonga kubintu bimwe na bimwe byinjira, bagahuza ingufu za HDG. Ariko isesengura ryibiciro byubuzima ryerekanaga ko muri kiriya kirere cyangirika cyane, ndetse na 316 idafite ingese ishobora gukenera kwitabwaho, mugihe igicucu cyinshi, cyashyizwe mu bikorwa neza cya HDG ku cyuma cya karubone gishobora kuba cyarenze ikibaho ubwacyo. Icyemezo cyagarutse kuri HDG. Guhitamo kurambye ntabwo buri gihe ari hamwe nagatabo gasa nicyatsi kibisi.

Ibikoresho byo gutanga no gutanga urunigi

Dore ikintu impapuro zihariye zitakubwira: gushakisha ibintu bihoraho, byujuje ubuziranenge bwa HDG bifata ku gipimo ntabwo ari gito. Ubunini bwa coating burashobora gutandukana mugice kimwe. Nagize ibyatanzwe aho gusezerana kumutwe bidahuye kuko galvanizing yubatse byinshi mugice kimwe. Ukeneye utanga ibintu bifite gahunda igoye, ntabwo ari umurongo wa galvanizing gusa.

Aha niho gufatanya nu ruganda rwinjijwe mu bidukikije bikuze mu nganda bigira icyo bihindura. Fata isosiyete nka Hamagara zitai yihuta ukora co., Ltd.. Bikorewe muri Yongnian, Handan-umutima wumusaruro wihuse wubushinwa-bazengurutswe nuruhererekane rwo gutanga, kuva gushushanya insinga kugeza kumpera yanyuma. Aho biherereye hafi yinzira nini zo gutwara abantu (https://www.zitaifacens.com inoti zegeranye na gari ya moshi ya Beijing-Guangzhou na gari ya moshi) ntabwo ari aho kugurisha gusa; bivuze ko imyuka ihumanya ikirere kubikoresho fatizo nibicuruzwa byarangiye. Iyo uwaguhaye isoko ari hagati yikigo kinini gisanzwe cy’ibicuruzwa mu Bushinwa, barashobora kubona ubuziranenge bwibyuma hamwe nabafatanyabikorwa ba galvanizing bakoranye imyaka myinshi. Ukwo gushikama ninkingi yihishe yo kuramba-kugabanya ibyago byibyiciro bitagenda neza.

Uburyo bwo Kunanirwa: Mubyukuri bigenda nabi

Kuramba nabyo ni ukwirinda gutsindwa. Bolt ya HDG ntabwo yangirika gusa. Ingingo zananiranye zisanzwe ziri kumutwe, aho igifuniko gishobora kuba cyoroshye, kandi munsi yumutwaro urambye aho guhagarika umutima bishobora gutangirira. Nabonye bolts ku kwaguka kwikiraro aho guhora micro-kugenda yambaraga muri zinc mugace, biganisha kubwo kwihuta. Ibisigaye bya bolt byasaga nkibishya.

Ikindi kibazo cyihishe ni galvanic ruswa. Guhuza ibyuma bya HDG hamwe nicyuma gito (nka aluminium) ahantu hatose birashobora kwihuta kwangirika kwa aluminium. Ibinyuranye, kubihuza nicyuma cyiza cyane nkumuringa birashobora gutamba zinc ku gipimo cyihuse. Ugomba gutekereza ku nteko yose. Kugaragaza HDG utitaye kubikoresho byo gushyingiranwa ni ikosa rya rokie isanzwe ibangamira igihe kirekire uriha.

Noneho hari ubushyuhe. Ipitingi ya HDG ninziza mubihe byinshi bidukikije, ariko mugihe gikomeza ubushyuhe bwo hejuru (burigihe hejuru ya 200 ° C), zinc irashobora gukwirakwira mubyuma, igakora igicucu kandi igatakaza agaciro kayo. Kubikorwa byo gutekesha ibyuka, twagombaga guhindukira kuri cinc-nikel ikwirakwizwa. Byari isomo ko HDG isanzwe ifite aho igarukira, kandi kuyikoresha buhumyi ntabwo ari injeniyeri irambye.

Icyemezo: Yego Yujuje ibyangombwa, Hamwe n'amaso atyaye

None, ese hot-dip galvanised bolts irambye muruganda? Ibyo mfata ni yego yujuje ibyangombwa, ariko iyo bishyizwe mubikorwa byimbitse kandi byuzuye. Ni igisubizo gikomeye, cyemejwe kubikorwa byinshi byinganda rusange, ubwubatsi, nibikorwa remezo aho kurwanya ruswa igihe kirekire hamwe no kubungabunga bike niyo ntego. Kuramba kwabo kumurika mugice cyo gukoresha.

Ariko, ntabwo aribisobanuro rusange, bidafite ibitekerezo. Ikiramba kirambye gishingiye kubisobanuro bikwiye (urwego, ubunini bwikigero kugeza kurwego), kugenzura ubuziranenge mugihe cyo gukora, no gushiraho neza no guhuza nibindi bikoresho. Bisaba kubaza uwaguhaye ibibazo bikomeye kubijyanye nibikorwa byabo, inkomoko yicyuma, hamwe na protocole yabo yo kugerageza.

Mu kurangiza, kwihuta kurambye kuramba nimwe guhuza intego, bikozwe hamwe n’imyanda igenzurwa, kandi bikamara igihe cyose imiterere ifatanyijemo - ntakindi, nta munsi. Kubisabwa bitabarika, HDG ikubita icyo kimenyetso. Ariko dufate ko buri gihe ari igisubizo niho twe, nkinganda, dushobora kuba abanebwe. Nigikoresho, cyiza cyane, ariko ntabwo ari amarozi. Kuramba kwukuri guturuka kubuhanga inyuma yo guhitamo no gukoresha.
