Galvanizing zitsulo ndi manja awo: Njira yaikulu

mankhwala zitsulo pa ntchito kuwononga. Ngati chitetezo ku nthaka waya zitsulo. izi luso mankhwala mu nyumba ndi Kufikika ndithu. Nkofunika kusankha bwino mankhwala njira.

Kodi galvanizing

Ziwalo zonse zitsulo ongoyendayenda amawasonyeza mosiyanasiyana njira zikuwononga. Kuchita popanda izo. Ndipo ndondomeko izi zitha kulephereka. Ndi cholinga ichi, ndipo ntchito mankhwala ndi nthaka. Izi kusankha zinthu si mwangozi. kusankha wapangidwa potengera makhalidwe a zigawo ziwiri: zitsulo ndi nthaka. Nthaka ali zambiri electronegative mlandu, osati zitsulo. Zikagwiritsidwa ntchito m'myoyo ❖ kuyanika katundu zitsulo nthaka popangidwa ndi galvanic lumikiza pakati pa zitsulo ndi nthaka. Mu njira iyi, mchikakamizo cha zinthu zakunja yozungulira yatikhudza ndi nthaka. zosiyanasiyana mankhwala ndi nawo zitsulo mochedwa. Ndipo adzapitiriza kwa nthawi yaitali ❖ kuyanika nthaka si zinawonongekeratu.

Nthawi kumene ❖ kuyanika nthaka imaphwanya, chitetezo lidakali. Ichi ndi chifukwa chakuti nthaka amachitira ndi mpweya mu mlengalenga. Chifukwa cha mankhwala zako nthaka hydroxide aumbike. A mankhwala kuperekedwa komanso ali ndi katundu zozitetezera. Choncho, kanasonkhezereka zitsulo lidakali.

njira galvanizing

Galvanizing katundu zitsulo ndi njira yotchuka kwambiri kulimbana ndi dzimbiri. Ichi ndi chifukwa chiŵerengero mkulu chifukwa yoyesedwa ndi mtengo angagulidwe. The njira zotsatirazi ntchito kanasonkhezereka zitsulo:

• wozizira;
• chamoto;
• galvanic;
• thermodiffusion;
• matenthedwe kutsitsi.

Kusankha njira yabwino kwambiri, choyamba muyenera kudziwa zinthu zimene tinachita zidzagwiritsidwanso ntchito m'tsogolo. Galvanizing khalidwe zimadalira makulidwe ❖ kuyanika, nthawi ndi chitetezo kutentha. Galvanizing zitsulo ndi manja awo ndi Zimatheka m'njira ziwiri: ozizira ndi yokutidwa. Dziwani kuti durability mbali ngati ankachitira kudzadalira zinthu opaleshoni. Wosanjikiza nthaka mosavuta pansi mantha mawotchi.

otentha mafashoni

Hot galvanizing wa zitsulo ndi njira othandiza kwambiri. Mankhwala mankhwala reagents ntchito mankhwala pamwamba. Iwo amakonzedwa mwa ntchito zitsulo pachimake kwa ndondomekoyi. Ndi chifukwa ichi pali vuto zachilengedwe. The nthaka kukodzedwa ntchito ndondomekoyi. The mankhwala okonzeka chabe choviikidwa mu kusamba nthaka chosungunula.

zipangizo zina zapadera chofunika kwa ndondomekoyi. Choncho, njira imeneyi si abwino chifukwa zitsulo kanasonkhezereka kunyumba.

matenthedwe njira mayamwidwe

kanasonkhezereka zitsulo ndi ndondomeko amatenda malowedwe a maatomu nthaka mu kapangidwe ka mankhwala zitsulo kupanga aloyi chitsulo nthaka ndi dongosolo zovuta. Ntchito yonse kukuchitika kutentha kwambiri. Pa kutentha pa 2600 madigiri nthaka akudutsa mu boma gaseous. Sachoka malo, kumene katundu zitsulo, wodzazidwa ndi ufa nthaka-okhala. Oyenera njira kutsatira wosanjikiza, amene makulidwe kuposa 15 micrometers. Chifukwa ❖ kuyanika zoteteza kuti kukana angayerekezedwe ndi wosanjikiza ntchito ndi otentha. Chifukwa cha kufunika kwa kulenga zinthu zina si oyenera kudziletsa kuzindikira.

Gasi matenthedwe njira

Mu njira imeneyi, nthaka, umene uli mu mawonekedwe a ufa, otaya mpweya sprayed padziko katundu zitsulo. Pamaso kupopera zinthu anasungunuka ndi kutentha ndi boma ndi adatchithisira mwatsatanetsatane. Galvanizing zitsulo amakhala ndi Mofananamo milandu kumene katundu zitsulo ndi chachikulu.

Mbali A njira ndi wosanjikiza zoteteza ali zambiri pores. Kudzaza mankhwala awo ali ndi utoto. wosanjikiza Izi zipangizo awiri okhoza ukhale kwa zaka 30. njira zimenezi sizingatheke akuyendera kunyumba.

Cold galvanizing kunyumba

Palinso galvanizing ozizira. Kanasonkhezereka zitsulo njira imeneyi ntchito kwa zachitsulo nthaka mankhwala mu mawonekedwe a utoto. Opanga kupereka kusankha lonse la ndalama izi. Ndipo pachimake nyimbo (mwachitsanzo, nthaka misa kachigawo m'nkhaniyo) Kodi ndi wosiyana kwambiri ndi mzake. Zimaonekeratu kuti zotsatira za mankhwala adzakhala zosiyanasiyana.

Zikutanthauza kuti galvanizing ndi zingapo zochititsa. Ena amafuna mkulu amasokoneza maphunziro. Yotsirizira ndi otsika guluu wolimba luso, chifukwa amene pambuyo atayanika anayamba flake. Enanso okutidwa pambuyo ntchito "cobweb" kuchokera ming'alu. Chachinayi akhoza ntchito molumikizana yekha ndi solvents mtundu. Chachisanu amafuna kugwiritsa ntchito zipangizo zina zapadera.

Chida ichi ndi bayinare. Choncho, pamaso kugwiritsa ntchito zipangizo awiri (ufa ndi binder) ayenera wothira mzake. Kodi izi mu chiŵerengero 3 1 kapena 1 1. Ntchito yonse iyenera kuchitikira yekha akamaziwononga. Mlengalenga kutentha ayenera kukhala abwino ndi mu osiyanasiyana kuchokera madigiri 5 mpaka 40. Mu chinyezi choncho ndi ku 30 98%. Chipinda chimene ndondomeko ayenera kukhala mpweya wabwino. Pambuyo ntchito, ayenera bwinobwino kuiulutsa. Mtumiki umagwiritsidwa ntchito zigawo ziwiri ndi imeneyi pafupifupi 30 minutes. Pambuyo tsiku lina mankhwala akhoza TACHIMATA ndi nyimbo utoto. Pa galvanizing n'kofunika kusunga malamulo chitetezo. ntchito zonse ikuchitika ntchito zinthu zodzitetezera.

njira electroplating

Kanasonkhezereka zitsulo pakhomo angathe kuchitidwa ndi electroplating. Pakuti mankhwala koyamba kulitsuka. Kenako, item akutsikira kwa masekondi angapo (2 10) mu chidulo sulfuric. Pambuyo pake, mankhwala ndi osambitsidwa madzi. Pokonzekera izi kwa anodization amaliza. Pakuti unsembe pansi galvanizing mbale ayenera osankhidwa zipangizo inert, mwachitsanzo, galasi. Tara amusankha mu njira yakuti accommodates tsatanetsatane ndi elekitirodi Ufumuyo.

panopa gwero naupereka ndi 6-12 ndi 2-6 A. Mu okonzeka electrolyte zina - njira ya mchere iliyonse, kotero mu madzi. Zochita bwino kutenga nthaka mchere. Inu mukhoza kutenga asidi kuchepetsa sulfuric (monga batire) ndi kuwonjezera nthaka. Chifukwa cha zochita mankhwala lidzasinthidwa asidi insoluble mchere ndi precipitates. nthaka A kukhala mu njira. precipitate ayenera kuchotsedwa, chabe kukhetsa njira.

Nthaka elekitirodi amapangidwa chidutswa nthaka anathandiza pa waya mkuwa. Kuchokera "opanda" batire naupereka umaperekedwa kwa workpiece, ndi "kuphatikiza" - kuti nthaka. Choncho, elekitirodi nthaka uli kusungunuka ndipo maatomu onse nthaka kukhazikika pa workpiece lapansi.

Pomaliza

zitsulo galvanizing kunyumba - sikutha weniweni. Kukhazikitsa ake ayenera kugula zipangizo. Mwachitsanzo, utoto nthaka ofotokoza kapena kuzizira ndondomeko electroplating ndi nthaka chidutswa. Zodabwitsa ndizakuti, nthaka akhoza kukopedwa pa Msikiti zitsulo zotha.
