Black zinc-plated pini shaft kusimba? 

Ngatichekei kuburikidza nekushambadzira fluff. Kana mumwe munhu achinge abvunza nezve kusimba kwepini yakasviba zinc-yakapetwa, ivo vanowanzo tsvaga kuodzwa mwoyo kana kutarisira chishamiso. Haisi nyore hongu kana kwete. Mhinduro chaiyo inogara munharaunda yayakatarisana nayo, kunaka kwesimbi yepasi, uye kutaura chokwadi, maitiro ekuputira aidzorwa. Ndakaona mapini aya achikundikana mumwedzi uye anogara kwemakore, uye mutsauko unowanzo kudzika kune mamwe mapeji anoregeredza.

Iyo Core Kusanzwisisana: Black Zinc seKupera

Vanhu vazhinji vanonzwa zinc plating uye vanofunga kudzivirira ngura. Havana kukanganisa, asi chikamu chitema chinoshandura mutambo. Yakajairika yakajeka kana yebhuruu-inopenya zinc plating inopa kudzivirira kwechibairo. Iyo yakasviba kupera kazhinji ndeye chromate yekushandura coating yakaiswa pamusoro pe zinc. Iyi dema chromate layer inopa iyo ruvara uye yakati wandei kuramba kuonda kupfuura, toti, yero chromate, asi iri pamusoro pejasi. Kugara kwayo inhovo, kwete mhinganidzo yokuzviporesa. Kana iyo yakaonda dema dhiza yakakweshwa kana kupfekwa, iwe uri pasi kune zinc pazasi, uyezve kune simbi. Ndakave nevatengi vachigunun'una nezve ngura pamapini matsva eblack zinc mushure megungano nekuti chromate layer yakakanganiswa nekubata nemaoko kana maturusi isati yaiswa.

Iyo substrate inokosha zvikuru. Pini shaft yakagadzirwa kubva pasi-kabhoni simbi maringe neimwe kubva kugiredhi repamusoro senge 1045 kana kunyange isina tsvina ichave nemhedzisiro yakasiyana kana ngura yatanga. Iyo zinc plating inongova ganda. Kana iyo musimboti isina kusimba kana kungoita ngura mukati, kutadza kweplating ingori kutanga kwedambudziko. Iwe haugone kurongedza pamusoro pehurombo-mhando shaft uye kutarisira hupenyu hurefu.

Process control ndizvo zvese. Ndinorangarira ndichitsvaga maM6 nhema zinc dowel pins kubva kumutengesi wepano kuitira musangano usingakoshesi wemumba. Vaitaridzika zvakanaka. Asi mukati memwedzi mitanhatu munzvimbo inochengeterwa zvinhu ine mwando zvishoma, kuchena kuchena (zinc oxide) kwakatanga kutumbuka kuburikidza nejira dema. Nyaya yacho? Zvichida kusacheneswa kwakakwana kana kusukurudza tisati taputirwa, zvichisiya tsvina dzaiita kuti firimu riwedzere kuora. Kupera kweblack kwakavanza kusagadzirira zvakanaka kusvika nguva dzaenda.

Kuita Chaiyo-Yenyika: Zvese Nezvezvakatipoteredza

Kune yemukati, inodzorwa nharaunda - funga fenicha yehofisi, mukati mechanicha maassemblies, yakaoma ekuchengetedza masisitimu - yakanyatsoiswa dema zinc kupera inowanzogara yakasimba. Inopikisa kusvibiswa kweminwe uye inopa chimiro chakanaka, chakafanana. Kudzivirirwa kwecorrosion pano ndeyekudzivirira kusvibiswa pane kurwisa zvinhu zvine hukasha. Muzviitiko izvi, durability yakakwirira.

Ifambise kunze kana munzvimbo ine unyoro, uye nyaya inoshanduka. Kunyangwe hunyoro hunyoro hune tembiricha kutenderera kunogona kuve dambudziko. Ndakaita basa rekugadzira zvikwangwani zvekunze. Taishandisa mapini eblack zinc-plated for pivots. Vaitaridzika zvakanaka pakutanga, vachienderana nekunaka, asi muguta riri padyo nemahombekombe, ngura tsvuku yakatanga kuoneka painotakura nzvimbo mukati memwedzi gumi nemasere. Iko kusanganiswa kwehunyoro, dzimwe nguva munyu wekupfapfaidza, uye friction yaipfekwa kuburikidza nechromate uye zinc layer. Isu takadzidza kuti kune chero chine simba application kana kushandiswa kwekunze, zinc nhema chete ndeyekukanganisa pakusimba.

Kuvapo kwezvimwe zvinhu zvinokosha. Mumagungano ane aruminiyamu kana simbi dzakasiyana, galvanic corrosion inogona kudya pazinc plating nekukurumidza. Ndinoyeuka kukundikana kwembavha yemagetsi pakashandiswa pini yezingi nhema kuchengetedza bhasikoro remhangura. Vaviri vegalvanic vakawedzera corrosion, zvichikonzera kubatwa uye hope dzakaipa panguva yekugadziriswa. Iro dema rakaita kuti kuongorora kwekutanga kutaridzike kwakachena, kuvharidzira kuita kuri kuramba kuchiitika pazasi kusvika pini yanyatso sungirirwa panzvimbo.

Kuenzanisa kune Mamwe Mapedzi

Wadii kungoshandisa simbi isina tsvina? Mari uye galling, kazhinji. Asi nekuda kwekusimba mumamiriro ezvinhu akaoma, mapini asina tsvina kana kupisa-dip ari mune imwe ligi. Black zinc inoyevedza uye ine mwero-yekudzivirira sarudzo. Isu dzimwe nguva tinotsanangura dema zinc-yakarongedzwa mapini kubva kumugadziri akafanana Handan Zitai Fastener Kugadzira Co, Ltd. yemuchina wemukati umo iyo dema oxide inotaridzika inodiwa kuti yakaderera-mwenje kuoneka pakatarisana neakasviba mafuremu, asi isu tinoona kuti nharaunda yakavharwa uye nemafuta. Nzvimbo yavo muYongnian, iyo fastener yekugadzira hub, zvinoreva kuti vaona yese yekushandisa uye kutadza maitiro, ayo anowanzo shandura kune yakawedzera pragmatic maitiro ruzivo.

Mapoinzi Akakundikana: Kupi uye Sei Vachisakara

Kupokana ndiye muvengi mukuru. Chero pini shaft inoshanda sehinge, pivot, kana chinongedzo ichaona kupfeka. Iwo dema chromate uye zinc layers akakora mamicrons. Pasi pemitoro ye radial kana inotsvedza, vanomira nekukurumidza. Kana waenda, unowana simbi-pane-simbi kupfeka kana kukurumidza kuita ngura mugoro rakasakara. Ndakabvisa michina apo pakati pepini shaft paive nesimbi yakapenya, yakakwenenzverwa, uku migumo ichiri neblack coating. Kusimba kwacho kwaisava kwechinhu, asi kwekushandisa.

Migumo ine tambo (kana iripo) imwe nzvimbo isina simba. Iyo yekuisa pashinda inogona kukanganisa hukama hwe torque-tension uye inogerwa zviri nyore panguva yekuisa. Tambo dzebhaudhi dzepafudzi dema zingi dzinowanzoita ngura nekuti plating inokuvadzwa kana yadzvanywa panzvimbo. Icho chidimbu chinowanzo tariswa panguva yekutsanangurwa.

Hydrogen embrittlement imhondi yakanyarara, kunyanya kune simbi dzakasimba. Iyo acid yekuchenesa nhanho isati yaiswa zinc inogona kuunza haidrojeni musimbi, zvichitungamira kunonoke, brittle kuputsika pasi pemutoro. Iyi haisi nyaya yekupfeka asi kutadza kusimba kwekusimba. Vagadziri vane mukurumbira, senge iri pa https://www.zitafornasteers.com, ichange iine nzira yekubika yekubvisa iyi haidrojeni. Asi havasi vese vanoita, kunyanya nemabhechi akachipa. Uyu mubvunzo waunofanira kubvunza.

Kuita Kuti Ipedzisire: Inoshanda Kutsanangura uye Kubata

Usatarise dema zinc yekugara chete. Itarise kuti itaridzike nedivi rekusaonda, wobva wagadzira kuidzivirira. Ishandise mune static, yakaoma, kana lubricated application. Kana pini ichitenderera kana kutsvedza, ronga kubhura kana kuona kuti inogara ichizorwa. Iyo firimu yemafuta inowedzera dhizaini yekudzivirira iyo plating inoshaya.

Ongorora kupedzisa kana wagamuchira. Iyo yakanaka yeblack zinc plating inofanirwa kuve yakafanana, inoteedzera, uye isina mabhururu kana hupfu hwakasara. Ikweshe zvakasimba nemucheka muchena wakaoma. Kana masara matema akabuda, iyo chromate coating haina kuvharwa nemazvo uye inopa dziviriro shoma. Ndaramba kutumirwa kwebvunzo iri nyore.

Funga nezvekurapa kwepost-plating. Kune mamwe maapplication ari kudiwa zvishoma, wakisi kana mafuta dip mushure mekuputirwa inogona kuwedzera zvakanyanya kusaita ngura nekuisa chisimbiso ma pores ari muchromate layer. Iyo inhanho yakapfava, yakaderera-inodhura iyo vazhinji vatengesi vanopa asi haisi nguva dzose yakasarudzika.

Pakutenga vhoriyamu kubva kune hombe yekugadzira base, kujekesa mukutenga odha kwakakosha. Panzvimbo pekungoita zinc dema, tsanangura mwero (semuenzaniso, ASTM B633, Fe/Zn 5) uye inodiwa yemunyu yekupfapfaidza maawa ekuyedza (semuenzaniso, maawa makumi mapfumbamwe nematanhatu kusvika kuchena kuchena). Izvi zvinomanikidza nhaurirano yemhando yepamusoro. Kambani yakadai Handan Zitai Fastener, iri muchikamu chikuru cheChina chechikamu, chakagadzirirwa izvi zvikumbiro chaizvo. Kusvika kwavo kunzira huru dzekutakura zvinhu zvinoreva kuti vajaira kutakura kune dzakasiyana siyana mamiriro ekunze, izvo zvinoda kusimba kwakasimba kudzora maitiro.

Kutonga Kwekupedzisira: A Calculated Compromise

Saka, dema zinc-plated pini shaft inogara kwenguva refu? Inogona kuva, asi kwete pasi rose. Kugara kwayo kune zvimiso uye kazhinji kushoma pane tariro isingazivikanwe. Iko kupedzisa kunotengeserana yakanyanya corrosion kudzivirira kune chaiyo, yakaderera-glare aesthetic. Murudyi, nzvimbo yakadzivirirwa, ichapfuura muchina. Mune isiriyo, yakafumurwa, kana ine simba application, ichave yekugadziridza zvinyorwa.

Iyo nyanzvi inotora ndeyekuona sechikamu muhurongwa. Kusimba kwepini hakusi kwekuputira chete; iri pamusoro peimba, mutoro, mhepo, uye purogiramu yekugadzirisa. Ndakamira kuibata senge yakapfava isingaite ngura uye ndakatanga kuibata sechizoro chine mabhenefiti ekudzivirira ari pakati nepakati. Iko kushanduka kwepfungwa kunotungamira kune mamwe magadzirirwo akavimbika uye mashoma macallbacks.

Paunenge uchida iyo matte-dema kutaridzika, ishandise. Asi injinjini yakatenderedza zvisingakwanisi. Dzimwe nguva, mhinduro yakasimba ndeyekutsanangura pini yesimbi isina simbi uye iite black-oxided, kana kushandisa kabhoni simbi pini ine gobvu, yakasimba coating sejachi reupfu kune zvikamu zviri pachena. The dema zinc-yakarongedzwa pin shaft ine nzvimbo yaro—nzvimbo chaiyo, inonzwisiswa, uye yakanyatsosarudzwa. Kusimba kwayo kwechokwadi kunotemerwa kwete kufekitori, asi pabhodhi rako rekudhirowa uye munzvimbo yayo yekupedzisira yekushandisa.
