Iko kusarudzwa kwekurapwa kwemusoro idambudziko iro chero zviso zvese zvinogadzira. Kune akawanda marudzi ekurapa ekurapa ekurapa anowanikwa, uye mugadziri wepamusoro-soro haafanire kungofunga nezvehupfumi uye kushanda kweiyo dhizaini, asi zvakare teerera kugungano yegungano uye kunyange zvinodiwa nemamiriro ekunze. Pazasi pechiitiko pfupi kune zvimwe zvinowanzoshandiswa zvombo zvezvematanho zvinobva pamisimboti iri pamusoro apa, kureva nezvevarapi vezvimisikidzwa.
1. Electrollviizeiz
Zinc ndiye anonyanya kushandiswa kuunganidzwa kwekutengesa kwekutengesa. Mutengo wakachipa, uye kutaridzika kwakanaka. Mavara akajairika anosanganisira dema uye mauto girini. Nekudaro, maitiro ayo ekurwisa-corrosion ari avhareji, uye maitiro ayo ekurwisa-corrostion ndiyo yakaderera pakati pe zinc plating (coating) matanda. Kazhinji, kusarerekera kwemunyu kunosvimha mwero wegungwa kunoitwa mukati memaawa makumi manomwe neshanu, uye vanhu vakasarudzika vanoshandiswawo kuve nechokwadi chekuti kusarerekera kwemunyu kunopera kweanopfuura maawa mazana maviri. Nekudaro, mutengo unodhura, iro rine makirogiramu 5-8 izvo zvesimbi yakajairika yegungwa.
Maitiro ekugadzira emagetsi emagetsi abvumirana kuHydrogen embbrittlement, saka mabhebhi ari pamusoro pegiredhi 10.9 hazviwanzo kubatwa nearlanizing. Kunyangwe hydrogen inogona kubviswa ichishandisa oven mushure mekuputira, firimu rePassivation richakuvadzwa pakupisa pamusoro 60 ℃, saka hydrogen kubviswa mushure meMagetsi uye vasati vasati vapfuura. Izvi zvine preblability yakaipa uye yakakwirira yekugadzirisa mari. Muchokwadi, zvidyarwa zvizhinji zvekugadzira hazvibviri kubvisa hydrogen kunze kunze kwemvumo nevatengi chaiye.
Kuenderana pakati peTorque uye pre kusimbisa simba kwesimba rekuzvimirira kwakarongeka kune varombo uye kusagadzikana, uye hazviwanzo kushandiswa pakubatanidza zvikamu zvakakosha. Kuti uvandudze kuwirirana kweTorque preload, nzira yekubatanidza zvinhu zvinopenya mushure mekutanga inogona kushandiswawo kugadzirisa uye kuwedzera kubatana kweTorque preload.
2. Pephonzating
Iyi nheyo yakakosha ndeyekuti kudanwa kwacho kwakachipa kudhura kupfuura organizing, asi kupokana kwayo kwakashata kwakaipa pane organizing. Mushure mekufadzwa, mafuta anofanira kuiswa, uye kupokana kwaro kupesana kwakanyatsoenderana nekuita kwemafuta anoshandiswa. Semuenzaniso, mushure mekufadzwa, kushandisa general anti rust mafuta uye kuitisa kusarerekera kwemunyu kupfira bvunzo kwemazuva gumi egumi. Kushandisa yakakwirira-giredhi anti nzizi mafuta anokwanisa kutora kusvika kumaawa makumi manomwe nemasere-96. Asi mutengo wayo ndeyako katatu idzo dzaGeneral Fforating Mafuta.
Kune maviri anowanzo shandiswa mhando dzekufonera kune Fasteners, Zinc yakavakirwa phonzo uye manganese yakavakirwa. Zinc yakavakirwa phosphating ine basa rekunyora kupfuura manganse yakavakirwa pafoni, uye menganese yakavakirwa Inogona kushandiswa pakupisa kubva pamakumi maviri nemakumi maviri nemashanu kusvika mazana mana emadhigiria Fahrenheit (107-204 ℃). Kunyanya kubatana kwezvimwe zvakakosha zvikamu. Sekubatanidza tsvimbo bolts uye nzungu zveinjini, musoro wecylinder, mukuru kubereka, maFlywheel Bolts, vhiri bolts uye nzungu, nezvimwe.
Simba rakakwirira bolts dzinoshandisa kufonera, izvo zvinogona zvakare kudzivisa hydrogen embrittlement nyaya. Naizvozvo, mabhegi ari pamusoro pegiredhi 10.9 mumunda weindasitiri unowanzoshandisa phonzo yekufona.
3. Oxidation (blackening)
Blacking + Mafuta ndeyekuwedzera kuunganidza maindasitiri emaindasitiri nekuti ndiyo yakachipa uye inotaridzika zvakanaka usati washandiswa mafuta. Nekuda kwekutakura kwayo, hazvo hazvingangoita zvekudzivirira kwekudzivirira, saka zvichaitika nekukurumidza pasina mafuta. Kunyangwe muHupo hwemafuta, iyo Salt Spray bvunzo inogona kungogara kwemaawa 3-5.
4.. Electroplating kutsaura
Cadmium plating ine yakanakisa corrosion kuramba, kunyanya mumagariro emakemikidzi emakema, achienzaniswa nedzimwe nzvimbo yekurapa. Iyo marara yekurapa kurapwa kwemitengo yemubhadharo mukuita maElectroplating Cadmium yakakwira, uye mutengo wacho inenge makiromita gumi nemashanu ayo emagetsi eziso zinc. Saka hazvishandiswe mumaindasitiri evanhu, chete enzvimbo dzakananga. Fasteners anoshandiswa kune mafuta ekukwevera mafuta emuranda uye HNA Ndege.
5. Chromium plating
Iyo Chromic Coating yakamanikidzwa kwazvo mumamiriro ekunze, kwete nyore kuchinja ruvara uye kurasikirwa nekudyara, uye ine hutsinye uye nekuomarara kwakakwirira uye kunakisa kupfeka. Iko kushandiswa kwe chromium plating pane fasteners kunowanzoshandiswa kune zvinangwa zvekushongedza. Izvo hazviwanzo kushandiswa muminda yeindasitiri neyakanyanya kurwisa zvinodiwa zvinodiwa, sekunyepedzera kwakanaka kwekuzvidzora kwakaderera zvakaenzana nesimbi isina tsvina. Chete kana simbi yesimbi isina kukwana, chrome yakarongedzwa fasteners inoshandiswa pachinzvimbo.
Kuti udzivise Corrosion, mhangura uye nickel inofanira kutanga yatanga kutanga chrome pleting. Iyo chromium inobatanidza inogona kutsungirira tembiricha gumi nemaviri degrees Fahrenheit (650 ℃). Asi kune zvakare dambudziko re hydrogen embbrittlement, rakafanana neElectrollvizinization.
6. Nickel Plating
Inonyanya kushandiswa munzvimbo dzinoda zvese zvinopesana nehurongwa uye hukuru hwekuita. Semuenzaniso, magumo anobuda emabhatiri emotokari.
7. Kupisa-DIP arishenizing
Hot Dip Garanizing is a Hermal digfusion yekuvhara zinc yakatsikwa kune mvura. Kukakavara kukorama kuri pakati pegumi nemashanu kusvika zana μ m. Uye hazvisi nyore kudzora, asi zvine basa rakanaka rekushora uye rinowanzoshandiswa muinjiniya. Munguva yekupisa dip organizing maitiro, pane kusvibiswa kwakasimba, kusanganisira zinc marara uye zinc vapor.
Nekuda kwekukora kwekuchera, zvakakonzera matambudziko mukukwenenzvera mune zvemukati uye zvekunze tambo mumashandisirwo. Nekuda kwekudziya kwekupisa-dip kuwanda, hazvigone kushandiswa kune vanokurumidza pamusoro pegiredhi 10.9 (340 ~ 500 ℃).
8. Zinc Kupinda
Zinc indiltration is a solid metallurgical thermal digfusion coattion ye zinc poda. Yayo yekufanana kwayo yakanaka, uye yunifomu yunifomu inogona kuwanikwa mumarara nemakomba mapofu. Kuzeza uko ukobvu ndeye 10-110 μ m. Uye kukanganisa kunogona kudzorwa pa10%. Simba rayo rekubatanidza uye anti-corrostion performance neiyo substrate ndiyo yakanyanya kunaka muZinc machira (akadai maElectrolvizenizing, inopisa-dhiza-svutugadzike). Maitiro ayo ekugadzirisa arikusvibisa-akasununguka uye zvakanyanya zvakatipoteredza hushamwari.
9. Dachromet
Iko hakuna nyaya yehydrogen yembri yembri, uye iyo torque preload contragency kuita kwakanaka kwazvo. Pasina kufunga nezvechromium uye nenharaunda nyaya, Dachromet iri kunyatsokosha kune yakakwirira-simba masimba ane mishonga yakakwirira anti-corrosmion zvinodiwa.
